Endoscopic Hemostasis for Non-Variceal Upper Gastrointestinal Bleeding: New Frontiers: Adam Kichler, Sunguk Jang; Clin Endosc 2019;52(5):401-406. Published online July 16, 2019; DOI: https://doi.org/10.5946/ce.2018.103

Abstract PDF PubReader ePub

Non-variceal upper gastrointestinal bleeding (NVUGIB) refers to blood loss from the gastrointestinal tract proximal to the ligament of Treitz due to lesions that are non-variceal in origin. The distinction of the bleeding source as non-variceal is important in numerous aspects, but none more so than endoscopic approaches for successful hemostasis. When a patient presents with acute overt blood loss, NVUGIB is a medical emergency, which requires immediate intervention. There have been major strides in pharmacologic and endoscopic interventions for successful induction and remission of hemostasis in the last two decades. Despite achieving tangible improvements, the burden of the disease and the consequent mortality remain high. To address endoscopic outcomes better, several new technologies have emerged and have been subsequently incorporated to the armamentarium of hemostatic tools. This study aims to provide a succinct review on novel technologies for endoscopic hemostasis.

Endoscopic Therapy and Radiologic Intervention of Acute Gastroesophageal Variceal Bleeding: Jeong Eun Song, Byung Seok Kim; Clin Endosc 2019;52(5):407-415. Published online September 30, 2019; DOI: https://doi.org/10.5946/ce.2019.178

Abstract PDF PubReader ePub

Acute gastroesophageal variceal hemorrhage is a dreaded complication in patients with liver cirrhosis. Endoscopic therapy and radiologic intervention for gastroesophageal bleeding have rapidly developed in the recent decades. Endoscopic treatment is initially performed to stop variceal hemorrhage. For the treatment of esophageal variceal bleeding, endoscopic variceal ligation (EVL) is considered the endoscopic treatment of choice. In cases of gastric variceal hemorrhage, the type of gastric varices (GVs) is important in deciding the strategy of endoscopic treatment. Endoscopic variceal obturation (EVO) is recommended for fundal variceal bleeding. For the management of gastroesophageal varix type 1 bleeding, both EVO and EVL are available treatment options; however, EVO is preferred over EVL. If endoscopic management fails to control variceal hemorrhage, radiologic interventional modalities could be considered. Transjugular intrahepatic portosystemic shunt is a good option for rescue treatment in refractory variceal bleeding. In cases of refractory hemorrhage of GVs in patients with a gastrorenal shunt, balloon-occluded retrograde transvenous obliteration could be considered as a salvage treatment.

Endoscopic Management of Peptic Ulcer Bleeding: Recent Advances: Philip WY Chiu; Clin Endosc 2019;52(5):416-418. Published online August 13, 2019; DOI: https://doi.org/10.5946/ce.2018.182

Abstract PDF PubReader ePub

Bleeding peptic ulcers remained as one of the commonest causes of hospitalization worldwide. While endoscopic hemostasis serves as primary treatment for bleeding ulcers, rebleeding after endoscopic hemostasis becomes more and more difficult to manage as patients are usually poor surgical candidates with multiple comorbidities. Recent advances in management of bleeding peptic ulcers aimed to further reduce the rate of rebleeding through—(1) identification of high risk patients for rebleeding and mortality; (2) improvement in primary endoscopic hemostasis and; (3) prophylactic angiographic embolization of major arteries. The technique and clinical evidences for these approaches will be reviewed in the current article.

Endoscopic Therapy for Acute Diverticular Bleeding: Masayuki Kato; Clin Endosc 2019;52(5):419-425. Published online August 20, 2019; DOI: https://doi.org/10.5946/ce.2019.078

Abstract PDF PubReader ePub

Diverticular bleeding accounts for approximately 26%–40% of the cases of lower gastrointestinal bleeding. Rupture of the vasa recta at the neck or dome of the diverticula can be the cause of this bleeding. Colonoscopy aids in not only the diagnosis but also the treatment of diverticular bleeding after a steady bowel preparation. Endoscopic hemostasis involves several methods, such as injection/thermal contact therapy, clipping, endoscopic band ligation (EBL), hemostatic powder, and over-the-scope clips. Each endoscopic method can provide a secure initial hemostasis. With regard to the clinical outcomes after an endoscopic treatment, the methods reportedly have no significant differences in the initial hemostasis and early recurring bleeding; however, EBL might prevent the need for transcatheter arterial embolization or surgery. In contrast, the long-term outcomes of the endoscopic treatments, such as a late bleeding and recurrent bleeding at 1 and 2 years, are not well known for diverticular bleeding. With regard to a cure for diverticular bleeding, there should be an improvement in both the endoscopic methods and the multilateral perspectives, such as diet, medicines, interventional approaches, and surgery.

Abstract PDF PubReader ePub

The Korean Society of Gastrointestinal Endoscopy introduced the Accredited Endoscopy Unit Program to enhance endoscopy unit quality through systematic quality management in 2012. It was gradually expanded from training hospitals to institutions with 100+ beds, and the criteria for certification were applied according to the actual conditions of each institution. On the basis of the continuous communication with the institutions and feedback, the Accredited Endoscopy Unit Program certification criteria were revised in 2019 and introduced as follows: (1) the qualification criteria for endoscopy doctors and nurses; (2) facilities and equipment; (3) endoscopic examination process; (4) performance; (5) disinfection and infection control; and (6) endoscopic sedation. The assessment items consist of essential and recommended items. All essential items must be met for accreditation to be awarded. The assessment criteria for each evaluation area were revised as follows: (1) upgrading assessment criteria; (2) qualification of endoscopists and reinforcement of quality control education; (3) detailed standards for safety, disinfection, endoscopic sedation, and management instructions; and (4) presentation of new performance measurement of endoscopy and colonoscopy.

Abstract PDF PubReader ePub

A thorough disinfection and infection control process associated with gastrointestinal endoscopy is highly important for the health and safety of the examinee and the medical staff involved in the procedure. Endoscopic reprocessing and disinfection are two of the most important steps in quality control of endoscopy. In 2019, the Korean Society of Gastrointestinal Endoscopy updated the Accreditation of Qualified Endoscopy Unit assessment items for these quality indicators. Assessment of disinfection and infection control comprises 28 mandatory items in the categories of disinfection education, pre-cleaning, cleaning, disinfection, rinsing, drying, reprocessing, storage, endoscopic accessories, water bottle and connectors, space/facilities, personal protective equipment, disinfection ledger, and regulations regarding infection control and disinfection.
The updated Accreditation of Qualified Endoscopy Unit assessment items are useful for improving the quality of endoscopy by ensuring thorough inspection of endoscopic disinfection and infection control.

Sedation, defined as the depressed level of consciousness, induced by drug administration, is widely used for gastrointestinal endoscopy to relieve a patient’s anxiety and discomfort. In addition, successful procedure is anticipated with control of unintended movements. Endoscopic sedation, however, cannot be free from the risk of serious adverse events, e.g., cardiopulmonary compromise. Therefore, principles on personnel, facility and equipment, as well as performance itself, should be followed to prevent unfavorable incidents. In this article, sedation guidelines for the Accreditation of Qualified Endoscopy Units, issued by the Korean Society of Gastrointestinal Endoscopy, are presented.

Background
/Aims: Food bolus impaction is the most common form of esophageal foreign body impaction observed in adults. Clinical guidelines recommend using the push technique or retrieval methods in such cases. The push technique can cause injuries in certain clinical situations. Notably, conventional retrieval methods are time and effort consuming. Cap-assisted endoscopic extraction of an impacted food bolus is an easy and effective technique; however, more data are needed for its validation. This study compared the capassisted extraction technique with conventional methods.
Methods
This prospective observational multicenter study compared the success and en bloc removal rates, total procedure time, and adverse events in both techniques..
Results
The study included 303 patients who underwent food bolus extraction. The push technique was used in 87 patients (28.7%) and a retrieval procedure in 216 patients (71.3%). Cap-assisted extraction was performed in 106 patients and retrieval using conventional methods in 110 patients. The cap-assisted technique was associated with a higher rate of en bloc removal (80.2% vs. 15%, p<0.01), shorter procedure time (6.9±3.5 min vs. 15.7±4.1 min, p<0.001), and fewer adverse events (0/106 vs. 9/110, p<0.001).
Conclusions
Cap-assisted extraction showed no adverse events, higher efficacy, and a shorter procedure time compared with conventional retrieval procedures.

Immunohistochemical Expression of Epithelial-Mesenchymal Transition Markers in Early Gastric Cancer: Cancer Tissue versus Noncancer Tissue: Hee Jae Jung, Su Jin Hong, Shin Hee Kim; Clin Endosc 2019;52(5):464-471. Published online May 22, 2019; DOI: https://doi.org/10.5946/ce.2018.181

Abstract PDF PubReader ePub

Background
/Aims: Epithelial-mesenchymal transition (EMT) is a developmental process, wherein the epithelial cells show reduced intercellular adhesions and acquire migratory fibroblastic properties. EMT is associated with downregulation in epithelial marker expression, abnormal translocation of E-cadherin, and upregulation in mesenchymal marker expression. Here, we investigated the immunohistochemical (IHC) expression of EMT markers in early gastric cancer (EGC) between cancer and noncancer tissues.
Methods
Tissue samples were prospectively obtained from 19 patients with EGC that underwent endoscopic submucosal dissection (ESD). We compared the expression level of transforming growth factor (TGF)-β, vascular endothelial growth factor (VEGF), E-cadherin, α-smooth muscle actin (α-SMA), and vimentin between cancer and noncancer tissues using IHC. Among the 19 patients, 15 patients had follow-up biopsy at 3 months after ESD for EGC.
Results
Cancer tissues presented higher values of EMT mesenchymal markers (α-SMA/vimentin/TGF-β/VEGF) than the noncancerous tissues (p<0.05) that were significantly low after ESD (p<0.05). No significant correlation was reported for tumor location and initial Helicobacter pylori infection.
Conclusions
The mesenchymal expression of EMT markers was higher in the cancerous tissues than in the noncancer tissues.

Abstract PDF PubReader ePub

Background
/Aims: Platelet-rich plasma (PRP) has been used for wound healing in various medical fields. The aim of this study was to evaluate the clinical efficacy and safety of local PRP injections after endoscopic submucosal dissection (ESD).
Methods
Patients were non-randomly divided into the following two groups: (1) control group in which patients were administered only an intravenous proton pump inhibitor (PPI), and (2) a study group in which patients were administered an intravenous PPI and a topical PRP injection. We assessed the reduction in the ulcer area and stage of the ulcer after the procedure (24 hours, 48 hours, and 28 days after endoscopic surgery).
Results
We enrolled 7 study and 7 control patients. In the study group, the rate of ulcer reduction was 59% compared to 52% in the control group (p=0.372), 28 days after ESD. There were 5 patients in the S stage and 2 patients in the H stage in the study group compared to no patient in the S stage and 7 patients in the H stage in the control group (p=0.05), 28 days after ESD. There were no serious complications in either group.
Conclusions
The local injection of PRP is a safe and effective procedure for ulcer healing after ESD.

Abstract PDF PubReader ePub

Background
/Aims: This study aimed to examine the diagnostic ability of endoscopic ultrasonography (EUS) for major vascular invasion in pancreatic cancer and to evaluate the relationship between EUS findings and pathological distance.
Methods
In total, 57 consecutive patients who underwent EUS for pancreatic cancer before surgery were retrospectively reviewed. EUS image findings were divided into four types according to the relationship between the tumor and major vessel (types 1 and 2: invasion, types 3 and 4: non-invasion). We also compared the EUS findings and pathologically measured distances between the tumors and evaluated vessels.
Results
The sensitivity, specificity, and accuracy of EUS diagnosis for vascular invasion were 89%, 92%, and 91%, respectively, in the veins and 83%, 94%, and 93%, respectively, in the arteries. The pathologically evaluated distances of cases with type 2 EUS findings were significantly shorter than those of cases with type 3 EUS findings in both the major veins (median [interquartile range], 96 [0–742] µm vs. 2,833 [1,076–5,694] µm, p=0.012) and arteries (623 [0–854] µm vs. 3,097 [1,396–6,000] µm, p=0.0061). All cases with a distance of ≥1,000 µm between the tumors and main vessels were correctly diagnosed.
Conclusions
Tumors at a distance ≥1,000 µm from the main vessels were correctly diagnosed by EUS.

A Nationwide Assessment of the “July Effect” and Predictors of Post-Endoscopic Retrograde Cholangiopancreatography Sepsis at Urban Teaching Hospitals in the United States: Rupak Desai, Upenkumar Patel, Shreyans Doshi, Dipen Zalavadia, Wardah Siddiq, Hitanshu Dave, Mohammad Bilal, Vikas Khullar, Hemant Goyal, Madhav Desai, Nihar Shah; Clin Endosc 2019;52(5):486-496. Published online May 27, 2019; DOI: https://doi.org/10.5946/ce.2018.190

Abstract PDF PubReader ePub

Background
/Aims: To analyze the incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) sepsis in the early (July to September) and later (October to June) academic months to assess the “July effect”.
Methods
The National Inpatient Sample (2010–2014) was used to identify ERCP-related adult hospitalizations at urban teaching hospitals by applying relevant procedure codes from the International Classification of Diseases, 9th revision, Clinical Modification. Post-ERCP outcomes were compared between the early and later academic months. A multivariate analysis was performed to evaluate the odds of post-ERCP sepsis and its predictors.
Results
Of 481,193 ERCP procedures carried out at urban teaching hospitals, 124,934 were performed during the early academic months. The demographics were comparable for ERCP procedures performed during the early and later academic months. A higher incidence (9.4% vs. 8.8%, p<0.001) and odds (odds ratio [OR], 1.07) of post-ERCP sepsis were observed in ERCP performed during the early academic months. The in-hospital mortality rate (7% vs. 7.5%, p=0.072), length of stay, and total hospital charges in patients with post-ERCP sepsis were also equivalent between the 2 time points. Pre-ERCP cholangitis (OR, 3.20) and post-ERCP complications such as cholangitis (OR, 6.27), perforation (OR, 3.93), and hemorrhage (OR, 1.42) were significant predictors of higher post-ERCP sepsis in procedures performed during the early academic months.
Conclusions
The July effect was present in the incidence of post-ERCP sepsis, and academic programs should take into consideration the predictors of post-ERCP sepsis to lower health-care burden.

New Diagnostic Approach for Esophageal Squamous Cell Neoplasms Using Linked Color Imaging and Blue Laser Imaging Combined with Iodine Staining: Masato Tsunoda, Yoshimasa Miura, Hiroyuki Osawa, Tsevelnorov Khurelbaatar, Mio Sakaguchi, Hisashi Fukuda, Alan Kawarai Lefor, Hironori Yamamoto; Clin Endosc 2019;52(5):497-501. Published online April 16, 2019; DOI: https://doi.org/10.5946/ce.2018.195

Abstract PDF PubReader ePub

A 62-year-old man with a flat early esophageal cancer was referred for endoscopic treatment. White light imaging revealed a pale red lesion, whereas linked color imaging (LCI) and blue laser imaging (BLI) yielded purple and brown images, respectively. Iodine staining demonstrated a large unstained area with a homogenous but very weak pink-color sign. This area appeared more clearly as purple and green on LCI and BLI, respectively; however, a different colored portion was observed at the 4 o’clock position inside the iodineunstained area. Histopathology findings of the resected specimen revealed squamous intraepithelial neoplasia at the 4 o’clock position and an esophageal squamous cell carcinoma in the remaining iodine-unstained area. LCI and BLI combined with iodine staining produce characteristic images that overcomes the pink-color sign, reflecting the histological features of a flat esophageal neoplasm. This new method is useful for detailed evaluation of early flat squamous cell neoplasms.

Endoscopic Submucosal Dissection Followed by Concurrent Chemoradiotherapy in Patients with Early Esophageal Cancer with a High Risk of Lymph Node Metastasis: Hee Kyung Kim, Weon Jin Ko, Chang-Il Kwon, Ga Won Song, In Kyun Yoo, Ji Hyun Song, Hak Su Kim, Joo Young Cho; Clin Endosc 2019;52(5):502-505. Published online May 14, 2019; DOI: https://doi.org/10.5946/ce.2018.176

Abstract PDF PubReader ePub

Endoscopic submucosal dissection is recommended as an alternative therapy for early esophageal cancer. However, achieving curative resection in this procedure remains controversial since precise prediction of lymph node metastasis can be difficult. Here, we present the preliminary results of endoscopic submucosal dissection followed by concurrent chemoradiotherapy for early esophageal cancer with a high risk of lymph node metastasis. From May 2006 to January 2014, six patients underwent concurrent chemoradiotherapy after endoscopic submucosal dissection with a median follow-up period of 63 months. No complications were encountered during concurrent chemoradiotherapy. Although local recurrence did not occur in all patients, two patients were diagnosed with metachronous cancer. Overall, the survival rate was 100%. Thus, endoscopic submucosal dissection followed by concurrent chemoradiotherapy may be a feasible treatment for early esophageal cancer in patients with a high risk of lymph node metastasis. Future prospective large-scale studies are warranted to confirm our results.

Duodenal Stricture due to Necrotizing Pancreatitis following Endoscopic Ultrasound-Guided Ethanol Ablation of a Pancreatic Cyst: A Case Report: Jung Won Chun, Sang Hyub Lee, Jin Ho Choi, Woo Hyun Paik, Ji Kon Ryu, Yong-Tae Kim; Clin Endosc 2019;52(5):510-515. Published online July 4, 2019; DOI: https://doi.org/10.5946/ce.2018.191

Abstract PDF PubReader ePub

The frequency of incidental detection of pancreatic cystic lesions (PCLs) is increasing because of the frequent use of cross-sectional imaging. The appropriate treatment for PCLs is challenging, and endoscopic ultrasound-guided ablation for PCLs has been reported in several studies. Although the feasibility and efficacy of this therapeutic modality have been shown, the safety issues associated with the procedure are still a concern. We present a case of a 61-year-old man who underwent ultrasound-guided ethanol ablation for PCL and needed repeated endoscopic balloon dilatation for severe duodenal stricture caused by necrotizing pancreatitis after the cyst ablation therapy.
