Safety and efficacy of trans-afferent loop endoscopic ultrasound-guided pancreaticojejunostomy for post pancreaticoduodenectomy anastomotic stricture using the forward-viewing echoendoscope: a retrospective study from Japan: Ahmed Sadek, Kazuo Hara, Nozomi Okuno, Shin Haba, Takamichi Kuwahara, Toshitaka Fukui, Minako Urata, Takashi Kondo, Yoshitaro Yamamoto, Kenneth Tachi; Received April 12, 2024 Accepted May 31, 2024 Published online August 26, 2024; DOI: https://doi.org/10.5946/ce.2024.089 [Epub ahead of print]

Graphical Abstract Abstract PDF Supplementary Material PubReader ePub: Background
/Aims: Endoscopic ultrasound (EUS)-guided pancreatic duct drainage is a well-established procedure for managing pancreaticojejunostomy anastomotic strictures (PJAS) post-Whipple surgery. In this study, we examined the effectiveness and safety of EUS-guided pancreaticojejunostomy (EUS-PJS).
Methods
This retrospective, single-arm study was performed at Aichi Cancer Center Hospital on 10 patients who underwent EUS-guided pancreaticojejunostomy through the afferent jejunal loop using a forward-viewing echoendoscope when endoscopic retrograde pancreatography failed. Our primary endpoint was technical success rate, defined as successful stent insertion. The secondary endpoints were early and late adverse events.
Results
A total of 10 patients underwent EUS-PJS between February 2019 and October 2023. The technical success rate was 100%. The median procedure time was 23.5 minutes. No remarkable early or late adverse events related to the procedure, except for fever, occurred in two patients. The median follow-up duration was 9.5 months, and the median number of stent exchanges was two. A stent-free state was achieved in three patients.
Conclusions
EUS-PJS for PJAS management after pancreaticoduodenectomy appears to be an effective and safe procedure with the potential advantages of fewer reinterventions and the creation of a permanent drainage fistula.

The evolution and current state of bariatric endoscopy in Western countries: Maria Valeria Matteo, Vincenzo Bove, Valerio Pontecorvi, Loredana Gualtieri, Giorgio Carlino, Cristiano Spada, Ivo Boškoski; Received September 29, 2023 Accepted January 14, 2024 Published online May 24, 2024; DOI: https://doi.org/10.5946/ce.2023.253 [Epub ahead of print]

Abstract PDF PubReader ePub: With the alarmingly increasing prevalence of obesity in the Western world, it has become necessary to provide more acceptable treatment options for patients with obesity. Minimally invasive endoscopic techniques are continuously evolving. Currently, metabolic and bariatric endoscopies encompass several different techniques that can offer significant weight loss and improvement in comorbidities with a favorable safety profile. Restrictive bariatric procedures include the use of intragastric balloons and gastric remodeling techniques with different suturing devices. Several studies have demonstrated the efficacy and safety of these techniques that are widely used in clinical practice. Small intestine-targeted metabolic endoscopy is an intriguing and rapidly evolving field of research, although it is not widespread in routine practice. These techniques include duodenal-jejunal bypass liners, duodenal mucosal resurfacing, and incisionless anastomoses. The aim of this review article is to provide a detailed update on the currently available bariatric endoscopy techniques in Western countries.

Prevalence and natural course of incidental gastric subepithelial tumors: Dae-Hyuk Heo, Min A Yang, Jae Sun Song, Won Dong Lee, Jin Woong Cho; Clin Endosc 2024;57(4):495-500. Published online March 29, 2024; DOI: https://doi.org/10.5946/ce.2023.124

Graphical Abstract Abstract PDF PubReader ePub

Background
/Aims: Gastric subepithelial tumors (SETs) are often encountered during the upper gastrointestinal endoscopic screening. We assessed the prevalence of gastric SETs and the risk factors for their progression.
Methods
We reviewed the electronic medical records of 30,754 patients who underwent upper gastrointestinal endoscopic screening at our medical center between January 2013 and December 2016.
Results
Among the 30,754 patients examined, 599 (1.94%) had gastric SETs. The prevalence increased with age and was 9.56% in patients aged ≥70 years. In total, 262 patients underwent serial endoscopy for more than 6 months. The median age was 68 years (interquartile range [IQR], 61–74), and the number of females was 167 (63.7%). During a median follow-up of 58 months (IQR, 38–75), 22 patients (8.4%) showed significant changes in tumor size. An irregular border (odds ratio, 4.623; 95% confidence interval, 1.093–19.558; p=0.037) was a significant risk factor for progression. Seven patients underwent surgical or endoscopic resections. The pathologies of gastric SETs included leiomyomas (n=3), gastrointestinal stromal tumors (n=2), and lipomas (n=2).
Conclusions
The prevalence of gastric SETs increases with age. Most gastric SETs do not progress during long-term endoscopic examinations, and the risk of an increase in size is low in asymptomatic small SETs without irregular borders.

Graphical Abstract Abstract PDF PubReader ePub

Background
/Aims: Hypoxemia is a common side effect of propofol sedation during endoscopy. Applying mild positive airway pressure (PAP) using a nasal mask may offer a simple way to reduce such events and optimize the conditions for diagnostic and therapeutic upper gastrointestinal endoscopies.
Methods
We compared overweight patients (body mass index >25 kg/m2) with a nasal PAP mask or standard nasal cannula undergoing upper gastrointestinal endoscopies by non-anesthesiologists who provided propofol sedation. Outcome parameters included the frequency and severity of hypoxemic episodes.
Results
We analyzed 102 procedures in 51 patients with nasal PAP masks and 51 controls. Episodes of hypoxemia (oxygen saturation [SpO2] <90% at any time during sedation) occurred in 25 (49.0%) controls compared to 8 (15.7%) patients with nasal PAP masks (p<0.001). Severe hypoxemia (SpO2 <80%) occurred in three individuals (5.9%) in both groups. The mean delta between baseline SpO2 and the lowest SpO2 recorded was significantly decreased among patients with nasal PAP mask compared to controls (3.7 and 8.2 percentage points difference, respectively). There were significantly fewer airway interventions performed in the nasal PAP mask group (15.7% vs. 41.2%, p=0.008).
Conclusions
Using a nasal PAP mask may be a simple means of increasing patient safety and ease of examination.

Abstract PDF PubReader ePub

In the highly contagious coronavirus disease 2019 pandemic, aerosol-generating procedures (AGPs) are associated with high-risk of transmission. Upper gastrointestinal endoscopy is a procedure with the potential to cause dissemination of bodily fluids. At present, there is no consensus that endoscopy is defined as an AGP. This review discusses the current evidence on this topic with additional management. Prevailing publications on coronavirus related to upper gastrointestinal endoscopy and aerosolization from the PubMed and Scopus databases were searched and reviewed. Comparative quantitative analyses showed a significant elevation of particle numbers, implying that aerosols were generated by upper gastrointestinal endoscopy. The associated source events have also been reported. To reduce the dispersion, certain protective measures have been developed. Endoscopic unit protocols are recommended for the concerned personnel. Therefore, upper gastrointestinal endoscopy should be classified as an AGP. Proper practices should be adopted by healthcare workers and patients.

Abstract PDF PubReader ePub

Over the past decade, technological advances in deep learning have led to the introduction of artificial intelligence (AI) in medical imaging. The most commonly used structure in image recognition is the convolutional neural network, which mimics the action of the human visual cortex. The applications of AI in gastrointestinal endoscopy are diverse. Computer-aided diagnosis has achieved remarkable outcomes with recent improvements in machine-learning techniques and advances in computer performance. Despite some hurdles, the implementation of AI-assisted clinical practice is expected to aid endoscopists in real-time decision-making. In this summary, we reviewed state-of-the-art AI in the field of gastrointestinal endoscopy and offered a practical guide for building a learning image dataset for algorithm development.

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: This study aimed to assess the efficacy of a novel aerosol-exposure protection (AP) mask in preventing coronavirus disease in healthcare professionals during upper gastrointestinal endoscopy and to evaluate its clinical feasibility.
Methods
In Study 1, three healthy volunteers volitionally coughed with and without the AP mask in a cleanroom. Microparticles were visualized and counted with a specific measurement system and compared with and without the AP mask. In Study 2, 30 patients underwent endoscopic resection with the AP mask covering the face, and the SpO2 was measured throughout the procedure.
Results
In Study 1, the median number of microparticles in volunteers 1, 2, and 3 with and without the AP mask was 8.5 and 110.0, 7.0 and 51.5, and 8.0 and 95.0, respectively (p<0.01). Using the AP mask, microparticles were reduced by approximately 92%. The median distances of microparticle scattering without the AP mask were 60, 0, and 68 in volunteers 1, 2, and 3, respectively. In Study 2, the mean SpO2 was 96.3%, and desaturation occurred in three patients.
Conclusion
The AP mask could provide protection from aerosol exposure and can be safely used for endoscopy in clinical practice.

Abstract PDF Supplementary Material PubReader ePub

Endocytoscopy (EC) is a contact-type optical endoscope that allows in vivo cellular observation during gastrointestinal endoscopy and is now commercially available not only in Japan but also in Asian, European Union, and Middle Eastern countries. EC helps conduct a highly accurate pathological prediction without biopsy. Initially, EC was reported to be effective for esophageal diseases. Subsequently, its efficacy for stomach and colorectal diseases has been reported. In this narrative review, we searched for clinical studies that investigated the efficacy of EC. EC seems to accurately diagnose gastrointestinal diseases without biopsy. Most of the studies aimed to clarify the relationship between endocytoscopic findings of gastrointestinal neoplasia and pathological diagnosis. Some studies have investigated non-epithelial lesions or diseases, such as inflammatory bowel disease or infectious diseases. However, there are few high-level pieces of evidence, such as randomized trials; thus, further studies are needed.

Abstract PDF PubReader ePub

Hypoxemia is a frequent and potentially fatal complication occurring in patients during gastrointestinal endoscopy. The administration of propofol sedation increases the risk of most complications, especially hypoxemia. Nevertheless, propofol has been increasingly used in the United States, and the trend is likely to increase in the years to come. Patient satisfaction and endoscopist satisfaction along with rapid turnover are some of the touted reasons for this trend. However, propofol sedation generally implies deep sedation or general anesthesia. As a result, hypopnea and apnea frequently occur. Inadequate sedation and presence of irritable airway often cause coughing and laryngospasm, both leading to hypoxemia and potential cardiac arrest. Hence, prevention of hypoxemia is of paramount importance. Traditionally, standard nasal cannula is used to administer supplement oxygen. However, it cannot sufficiently provide continuous positive airway pressure (CPAP) or positive pressure ventilation. Device manufacturers have stepped in to fill this void and created many types of cannulas that provide apneic insufflation of oxygen and CPAP and eliminate dead space. Such measures decrease the incidence of hypoxemia. This review aimed to provide essential information of some of these devices.

Background
/Aims: The coronavirus disease 2019 (COVID-19) pandemic has necessitated modifications to allow the safe practice of clinical gastroenterology and gastrointestinal endoscopy. This study aimed to investigate the characteristics of clinical gastroenterology and gastrointestinal endoscopy practices during the COVID-19 pandemic in Indonesia.
Methods
This cross-sectional study enrolled physician members of the Indonesian Society for Digestive Endoscopy. We used an online self-administered questionnaire disseminated via social media. The 32-item survey determined the baseline characteristics of the participants, characteristics of clinical gastroenterology and gastrointestinal endoscopy practices, involvement of the physicians in the management of COVID-19, and overall impact of the pandemic on practice. All collected data were analyzed using descriptive statistics.
Results
The 200 participants in this study had a median age of 50 (34–76) years. Modifications in clinical gastroenterology practice were frequently reported in the outpatient (95.5%) and inpatient (100%) settings. All participants reported changes in the gastrointestinal endoscopy practice patterns. Of the participants, 86.0% were working in high-risk zones, and several of them reported inadequate protective personal equipment (34.0%). The median overall impact score of the pandemic on practice was 9 (2–10).
Conclusions
Physicians practicing clinical gastroenterology and gastrointestinal endoscopy in Indonesia work in high-risk settings. Modifications in clinical gastroenterology and gastrointestinal endoscopy practices are prevalent during the COVID-19 pandemic.

Abstract PDF PubReader ePub

The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

Introduction to Starting Upper Gastrointestinal Endoscopy: Proper Insertion, Complete Observation, and Appropriate Photographing: Kyung Sik Park; Clin Endosc 2015;48(4):279-284. Published online July 24, 2015; DOI: https://doi.org/10.5946/ce.2015.48.4.279

Abstract PDF PubReader ePub

Diagnostic upper gastrointestinal endoscopy is the most basic of endoscopy procedures and is the technique that trainee doctors first learn. Mastering the basics of endoscopy is very important because when this process is imprecise or performed incorrectly, it can severely affect a patient's health or life. Although there are several guidelines and studies that consider these basics, there are still no standard recommendations for endoscopy in Korea. In this review, basic points, including proper endoscope insertion, precise observation without blind spots, and appropriate photographing, for upper gastrointestinal endoscopy will be discussed.

Social networks are useful in the study of relationships between individuals or entire populations, and the ties through which any given social unit connects. Those represent the convergence of the various social contacts of that unit. Consequently, the term "social networking service" (SNS) became extremely familiar. Similar to familiar SNSs, International Digestive Endoscopy Network (IDEN) 2014 was based on an international network composed of an impressive 2-day scientific program dealing with a variety of topics for gastrointestinal (GI) diseases, which connects physicians and researchers from all over the world. The scientific programs included live endoscopic demonstrations and provided cutting-edge information and practice tips as well as the latest advances concerning upper GI, lower GI, and pancreatobiliary endoscopy. IDEN 2014 featured American Society for Gastrointestinal Endoscopy-Korean Society of Gastrointestinal Endoscopy (ASGE-KSGE)-joint sessions prepared through cooperation between ASGE and KSGE. Furthermore, IDEN 2014 provided a special program for young scientists called the 'Asian Young Endoscopist Award Forum' to foster networks, with many young endoscopists from Asian countries taking an active interest and participation.

Early Gastric Cancer-Like Advanced Gastric Cancer versus Advanced Gastric Cancer-Like Early Gastric Cancer: Hyun Sik Park, Sun-Young Lee, Sung Noh Hong, Jeong Hwan Kim, In-Kyung Sung, Hyung Seok Park, Chan Sup Shim, Choon Jo Jin; Clin Endosc 2013;46(2):155-160. Published online March 31, 2013; DOI: https://doi.org/10.5946/ce.2013.46.2.155

Abstract PDF PubReader ePub

Background/Aims

Improvements in the endoscopic evaluation and management of gastric cancer have made it possible to determine the depth of invasion during endoscopic examination. The aim of this study was to elucidate the differences between early gastric cancer (EGC) that resembles advanced gastric cancer (AGC) and AGC that resembles EGC.

Methods

We retrieved cases of EGC-like AGC and AGC-like EGC from consecutive gastric cancers that had been completely resected. The endoscopic diagnoses and clinicopathological findings were analyzed.

Results

AGC-like EGCs were located mainly in the distal part of the stomach, whereas EGC-like AGCs were located mainly in the proximal part of the stomach (p<0.001). Sixty percent of AGC-like EGCs were moderately differentiated adenocarcinomas, while 64% of EGC-like AGCs were poorly differentiated adenocarcinomas (p=0.015). According to Lauren's classification, 68% of AGC-like EGCs were intestinal type, whereas 71% of EGC-like AGCs were diffuse type (p=0.020).

Conclusions

AGC-like EGCs predominate in the distal part of the stomach, while EGC-like AGCs predominate in the proximal part. When evaluating the depth of a gastric cancer, care should be taken not to underestimate measurements in proximal gastric cancers since they tend to be poorly-differentiated adenocarcinomas, in Lauren's diffuse type, and invade deeper than their endoscopic appearance might suggest.

Management of Non-Variceal Upper Gastrointestinal Bleeding: Seung Young Kim, Jong Jin Hyun, Sung Woo Jung, Sang Woo Lee; Clin Endosc 2012;45(3):220-223. Published online August 22, 2012; DOI: https://doi.org/10.5946/ce.2012.45.3.220

Abstract PDF PubReader ePub

Upper gastrointestinal bleeding (UGIB) is a critical condition that demands a quick and effective medical management. Non-variceal UGIB, especially peptic ulcer bleeding is the most significant cause. Appropriate assessment and treatment have a major influence on the prognosis of patients with UGIB. Initial fluids resuscitation and/or transfusion of red blood cells are necessary in patients with clinical evidence of intravascular volume depletion. Endoscopy is essential for diagnosis and treatment of UGIB, and should be provided within 24 hours after presentation of UGIB. Pre-endoscopic use of intravenous proton pump inhibitor (PPI) can downstage endoscopic signs of hemorrhage. Post-endoscopic use of high-dose intravenous PPI can reduce the risk of rebleeding and further interventions such as repeated endoscopy and surgery. Eradication of Helicobacter pylori and withdrawal of non-steroidal anti-inflammatory drugs are recommended to prevent recurrent bleeding.

Published online May 25, 2011

Abstract PDF: Rectal foreign bodies are rare clinical problem in South Korea. Although many foreign bodies can be extracted safely using endoscopic procedures, some patients require surgery. Here we describe the case of a 35-year-old male who presented with a rectosigmoid foreign body, a large carrot measuring 28×7 cm. Sigmoidoscopy revealed a carrot in the upper rectum extending to the sigmoid colon. Endoscopic removal failed. The surgeon unsuccessfully attempted to extract the carrot using various tools without spinal anesthesia. During the extraction attempt, the patient complained of sudden abdominal pain, and a simple x-ray revealed pneumoperitoneum. An emergency colotomy and removal of the foreign body was performed, followed by primary repair of the perforation and a colostomy. Three months later, the colostomy was repaired.

Published online April 28, 2011

Abstract PDF: The Korean Society of Gastrointestinal Endoscopy (KSGE) developed regulations and a gastrointestinal endoscopy board in 1995. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. Although endoscopic examinations are supervised by a specialist during a GI fellowship, some types of GI endoscopic examinations and treatments are difficult to obtain exposure. Fellows should acquire endoscopic skills through repeated independent endoscopic examinations after a GI fellowship. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform endoscopic examinations without a supervisor. This document is intended to provide the principles that the Committee of Education and Training of KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. KSGE will contribute to improving the quality of GI endoscopy by providing guidelines for fellowships and supervisors. (Korean J Gastrointest Endosc 2011;42:207-214)

A Deep Neck Infection Due to Esophageal Perforation That Was Caused by Upper Gastrointestinal Endoscopy: Sung Gon Shim, M.D., Hang Rak Lee, M.D., Kang Nyeong Lee, M.D., Oh Young Lee, M.D., Byung Chul Yoon, M.D., Ho Soon Choi, M.D., Joon Soo Hahm, M.D. and Kyung Tae, M.D.*; Korean J Gastrointest Endosc 2009;38(4):205-209. Published online April 30, 2009

Abstract PDF: Diagnostic upper gastrointestinal endoscopy is a very commonly performed procedure. Physicians use it as a safe diagnostic tool to evaluate patients with a wide range of problems and complaints, but it can cause several complications in few cases. Esophageal perforation is a rare complication of upper gastrointestinal endoscopy, but it is associated with a relatively high mortality rate. Surgical management is required in most such cases. However, medical treatment can be considered for selected patients who are without a large perforation or systemic effects such as sepsis. Deep neck abscess can develop in patients who have had difficult intubations, and this may be related to retropharyngeal trauma or unapparent perforations. We experienced a case of deep neck infection due to an esophageal perforation that developed as a complication of diagnostic upper gastrointestinal endoscopy, and we successfully treated this patient with incision and drainage.

The Evalution of Patient Anxiety Associated with Upper Gastrointestinal Endoscopy: Jin Su Jang, M.D., Moon Kyung Joo, M.D., Jin Nam Kim, M.D., Yong Sik Kim, M.D., Yoon Tae Jeen, M.D., Hoon Jai Chun, M.D., Hong Sik Lee, M.D., Sang Woo Lee, M.D., Jai Hyun Choi, M.D., Chang Duck Kim, M.D. and Ho Sang Ryu, M.D.; Korean J Gastrointest Endosc 2007;34(2):65-70. Published online March 2, 2007

Abstract PDF: Background
/Aims: Upper gastrointestinal (UGI) endoscopy is a necessary procedure for making the diagnosis of UGI diseases. However, it may evoke anxiety due to the procedural discomfort before endoscopy. There have been few detailed studies that have evaluated the anxiety of patients who undergo UGI endoscopy in Korea. The aim of this study is to evaluate the patient's anxiety associated with UGI endoscopy and to determine the methods to improve the tolerance of patients to UGI endoscopy. Methods: From May to September 2004, we assessed 38 patients who received UGI endoscopy for the first time as outpatients at Korea University, Anam Hospital. One group was examined with UGI endoscopy after being sedated. The patient's anxiety was rated at baseline and immediately before the procedure. Results: Endoscopy was associated with a significant increase in anxiety (prior to procedure, 48.53 vs. baseline, 43.58, p＜0.001) but not trait anxiety (43.92 vs. 43.63, p=0.70). The procedural anxiety was not influenced by gender, age or the education level, but it was correlated with conscious sedation (without CS, 5.67±0.23 vs. with CS, 4.06±0.16, p＜0.05). Conclusions: Sedating the patient during UGI endoscopy is an effective method to lower procedural anxiety.

Two Cases of Vocal Cord Paralysis Complicated by Upper Gastrointestinal Endoscopy: Sung Won Jung, M.D.; Korean J Gastrointest Endosc 2006;33(1):32-36. Published online July 30, 2006

Abstract PDF: Upper Gastrointestinal endoscopy is extensively used these days and its various complications, including cardiopulmonary disease, bleeding, perforation and infection, have been reported on, but vocal cord paralysis as a complication of endoscopy has not been reported on. The pressure on the larynx by the endoscopic tip itself or the gag reflex during endoscopy could cause vocal cord paralysis as the endoscopic tip passes through the pyriform sinus, which is close to the recurrent laryngeal nerve and arytenoid cartilage. We experienced two cases of vocal cord paralysis as complications of upper Gastrointestinal endoscopy and we report on them here. (Korean J Gastrointest Endosc 2006;33:32⁣36)

A Case of an Acute Huge Hemorrhagic Gastric Ulcer after an Endoscopic Mucosal Biopsy: So Ri Kim, M.D., Kyung Hoon Min, M.D., Sang Woo Nam, M.D., Hyun Chul Kim, M.D.,Yong Keun Cho, M.D., In Hee Kim, M.D., Soo Teik Lee, M.D. and Deuk Soo Ahn, M.D.; Korean J Gastrointest Endosc 2005;31(2):111-115. Published online August 30, 2005

Abstract PDF: Although most diagnostic upper gastrointestinal endoscopic procedures are performed on an outpatient basis with relatively low risk, complications related with these procedures can occur. The reported complications are cardiopulmonary complications, drug side effects, perforation, hemorrhage and infection. Hemorrhage may occur from the site of biopsy or polyp removal. It is usually minimal and heals spontaneously with or without endoscopic treatment and rarely requires transfusion or surgery. Acute hemorrhagic ulceration associated with endoscopic mucosal biopsy is very rare. We report a case of a 46-year-old woman with an acute hemorrhagic gastric ulcer after an endoscopic mucosal biopsy. She has been receiving upper gastrointestinal endoscopic examinations annually for the gastric polyp detected 4 years ago. Endoscopic mucosal biopsy was performed without complications. Twelve hours later, she admitted to the emergency room because of melena. Emergent upper gastrointestinal endoscopy showed an acute huge hemorrhagic ulceration along the antrum. She was treated conservatively and discharged 5 days later. (Korean J Gastrointest Endosc 2005;31:111⁣115)

Ingestion of a Mouthpiece Fragment during Intravenous: Seung Ryong Lee, M.D., Byoung Sik Mun, M.D., Heok Soo Ahn, M.D. and Seung Ok Lee, M.D.; Korean J Gastrointest Endosc 2003;26(1):31-34. Published online January 30, 2003

Abstract PDF: The demand for intravenous sedated upper gastrointestianl endoscopy is currently increasing steeply. Despite this trend, patient status complication due to this procedure is largerly neglected by most physicians. Recently, in three patients, mouthpiece fragment were left within the patients' body after intravenous sedated upper gastrointestinal endoscopy. They were transferred to our institution for the removal of the fragment. The patients complained of an uneasy sensation from within their body, around their necks and chests. After conducting therapeutic endoscopy, the fragment could be located around the distal part of their esophagus and within their stomach. The fragment were removed successfully by using snare in two patients, and by using forceps in another patient. (Korean J Gastrointest Endosc 2003; 26:31⁣34)

수면내시경 검사에서 Midazolam 전처치와 Flumazenil 길항작용에 대한 연구 ( Effectiveness of Flumazenil against Midazolam as Premedication for Upper Gastrointestinal Endoscopy ): Korean J Gastrointest Endosc 2000;21(1):518-524. Published online November 30, 1999

Abstract PDF: Background
/Aims : Midazolam is utilized as a premedication for uppoer gastrointestinal endoscopy. Midazolam has a more rapid onset of reaction than that of diazepam and its duration is shorter. But the Consciousness of premedicated patients has not been regained sooner. The Purpose of this study was to examine the effectiveness of flumazenil against midazolam as premedication for upper gastrointesinal endoscopy. Methods : Sixty patients underwent upper gastrointestinal endoscopy. These patients were divided to three groups: Group I included twenty patients without premedication; Group Ⅱ Included twenty patients with premedication of midazolam and then were not given an antisedative agent excluign of normal saline; and Group Ⅲ included the others with midazolam and flumazenil as an antisedative agent. Results : There was no change in vital signs after midazolam and flumazenil as an antisedative agent. Results : There was no change in vital signs after midazolam injection, compared with presedation value. Modified Steward Coma Scale showed a significant increase after flumazenil injection as an antagonist of midazolam. The assessment of the endoscopist and the comfort of patients were satisfactory. When the 40 patients were asked about their willingness to undergo the same procedure in the future, thirty-four patients responded favorably. Conclusion : Midazolam was safe and effective for sedation for upper gastrointestinal endoscopy. There was rapid regaining of consciousness with flumazenil indection after midazolam, so the use of flumazenil against midazolam injection also appeared to be effective.

상부 위장관 내시경 검사 시 전처치로서의 Propofol의 효과 ( Propofol as Premedication for Upper Gastrointestinal Endoscopy ): Korean J Gastrointest Endosc 2000;20(3):165-170. Published online November 30, 1999

Abstract PDF: Background
/Aims: Benzodiazepine is generally used when sedation is required for endoscopy, while propofol, a phenol-derived intravenous anesthetic agent, appears to have a more suitable phamacokinetic profile. The aim of this study was to evaluate the effectiveness and safety of propofol as premedication for upper gastrointestinal endoscopy. Methods: Between July 1998 and October 1998, 44 male patients and 70 female patients were involved in this study. The relative ease of upper gastrointestinal endoscopy, patient's tolerance, and amnestic effects on 64 patients with propofol was compared with 50 patients with non-sedation. Pulse rate and arterial oxygen saturation was monitored. The endoscopist and patients replied to a questionnaire. Results: Patients receiving propofol tolerated endoscopy much more than patients with non-sedation (p＜0.01). The change in pulse rate was less variable but arterial oxygen saturation showed a statistically significant decrease in patients receiving propofol (p＜0.01). Propofol induced complete amnesia in 93.7% of the patients and partial anesthesia in 4.7%. Most of the patients receiving propofol accepted the same sedative methods in their next endoscopy (p＜0.01). Conclusions: Propofol is highly effective, with a short recovery time and satisfaction of the patients, but careful monitoring is recommended because of its untoward effect of hypoxia. It is recommended that propofol be used as a premedication especially in patients who are apprehensive about a repeated endoscopy.

Propofol 지속정주를 이용한 상부소화관 내시경 ( Gastrointestinal Endoscopy under Sedation with a Continuous Infusion of Propofol ): Korean J Gastrointest Endosc 1999;19(5):706-715. Published online November 30, 1998

Abstract PDF: Background
/Aims: Propofol is a short-acting intravenous sedative-hypnotic agent that can be used as a hypnotics for upper gastrointestinal endoscopy. A study was conducted to evaluate the effectiveness and safety of propofol as a hypnotic agent for upper gastrointestinal endoscopy. Methods: From June to October 1998, twenty eight patients undergoing upper gastrointestinal endoscopy were to receive propofol. Vital signs and peripheral oxygen saturation (SpO2) were monitored by pulse oximetry during continuous infusion of propofol. Propofol (1% solution) was initially infused by 26.7 mg/kg/hr until loss of eyelash reflex and then titrated to 6∼10 mg/kg/hr according to the patient's response and vital sign. Propofol infusion was discontinued while the endoscopic fiber was removed. Recovery time was defined from discontinuation of infusion to positive Romberg test. Evaluation was made from the endoscopists' assessment, patients' satisfaction, patients' recall of the procedure, and consciousness of the patients. Results: It was discovered that systolic, diastolic pressure and heart rate were significantly decreased, compared to control group. But clinically significant changes were not found. Apnea did not exist. And the respiration rate was significantly increased during propofol infusion. Peripheral oxygen saturation (SpO2) was transiently decreased during endoscopy. 14 patients (50%) complained of transient dizziness. Pain and redness over the infusion site was not found. The mean total dose of propofol was 133.6 mg. The mean infusion time of propofol was 6.2 minutes. Mean response and recovery time was 3.7 2.1, 20.9 5.4 minutes. Endoscopists' assessment and patients' comfort for endoscopy were satisfactory. When we asked 28 patients about willingness to undergo the same procedure in the future, 27 patients (96.4%) agreed. Degree of amnesia after examination revealed total amnesia in 27 patients (96.4%), partial amnesia in 1 patients (3.6%), and recall was not. Conclusions: Propofol has beneficial effects as hypnotic for upper gastrointestinal endoscopy without significant alteration in cardiopulmonary parameters. Patients' and endoscopists' assessment is good. This suggest that propofol may be used more frequently as a kind of premedication, especially in the cases of repeated endoscopy.
