Submucosal Endoscopy, a New Era of Pure Natural Orifice Translumenal Endoscopic Surgery (NOTES)
Suck-Ho Lee, Won Young Cho, Joo Young Cho
Clin Endosc 2012;45(1):4-10.   Published online March 31, 2012
DOI: https://doi.org/10.5946/ce.2012.45.1.4
AbstractAbstract PDFPubReaderePub

Natural orifice translumenal endoscopic surgery (NOTES) involves the intentional perforation of the viscera with an endoscope to access the abdominal cavity and perform an intraabdominal operation. In a brief time period, NOTES has been shown to be feasible in laboratory animal and human studies. Easy access to the peritoneal cavity and complete gastric closure should be secured before NOTES can be recommended as an acceptable alternative in clinical practice. The concept of submucosal endoscopy has been introduced as a solution to overcome these two primary barriers to human NOTES application. Its offset entry/exit access method effectively prevents contamination and allows the rapid closure of the entry site with a simple mucosal apposition. In addition, it could be used as an endoscopic working space for various submucosal conditions. Herein, the detailed procedures, laboratory results and human application of the submucosal endoscopy will be reviewed.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

There is indirect evidence to suggest that 80% of colorectal cancers (CRC) develop from adenomatous polyps and that, on average, it takes 10 years for a small polyp to transform into invasive CRC. In multiple cohort studies, colonoscopic polypectomy has been shown to significantly reduce the expected incidence of CRC by 76% to 90%. Colonoscopic polypectomy is performed frequently in primary outpatient clinics and secondary and tertiary medical centers in Korea. However, there are no evidence-based, procedural guidelines for the appropriate performance of this procedure, including the technical aspects. For the guideline presented here, PubMed, Medline, and Cochrane Library literature searches were performed. When little or no data from well-designed prospective trials were available, an emphasis was placed on the results from large series and reports from recognized experts. Thus, these guidelines for colonoscopic polypectomy are based on a critical review of the available data as well as expert consensus. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data become available. This guideline is intended to be an educational device to provide information that may assist endoscopists in providing care to patients. This guideline is not a rule and should not be construed as a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment. Clinical decisions for any particular case involve a complex analysis of the patient's condition and the available courses of action.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

Now colorectal cancer is the second most common cancer in males and the fourth most common cancer in females in Korea. Since most of colorectal cancers occur after the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish Korean guideline for colorectal cancer screening and polyp detection. The guideline was developed by the Korean Multi-Society Take Force and we tried to establish the guideline by evidence-based methods. Parts of the statements were draw by systematic reviews and meta-analyses. Herein we discussed epidemiology of colorectal cancers and adenomas in Korea and optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

AbstractAbstract PDFSupplementary MaterialPubReaderePub

Postpolypectomy surveillance has become a major indication for colonoscopy as a result of increased use of screening colonoscopy in Korea. In this report, a careful analytic approach was used to address all available evidences to delineate the predictors for advanced neoplasia at surveillance colonoscopy and we elucidated the high risk findings of the index colonoscopy as follows: 3 or more adenomas, any adenoma larger than 10 mm, any tubulovillous or villous adenoma, any adenoma with high-grade dysplasia, and any serrated polyps larger than 10 mm. Surveillance colonoscopy should be performed five years after the index colonoscopy for those without any high-risk findings and three years after the index colonoscopy for those with one or more high risk findings. However, the surveillance interval can be shortened considering the quality of the index colonoscopy, the completeness of polypectomy, the patient's general condition, and family and medical history.

Background/Aims

It is believed that disposable biopsy forceps are more costly than reusable biopsy forceps. In this study, we evaluated performance and cost of disposable forceps versus reusable forceps in esophagogastroduodenoscopic biopsy.

Methods

Between October 2009 and July 2010, we enrolled 200 patients undergoing esophagogastroduodenoscopic biopsy at Seoul St. Mary's Hospital. Biopsies were performed with 100 disposable or 5 reusable forceps by random assignment. Seventy-five additional patients were studied to estimate durability of reusable forceps. The assisting nurses estimated the performance of the forceps. The evaluation of costs included purchase prices and reprocessing costs. The adequacy of the sample was estimated according to the diameter of the obtained tissue.

Results

Performance of disposable forceps was estimated as excellent in 97.0%, good in 2.0% and adequate in 1.0%. Reusable forceps were estimated as excellent in 36.0%, good in 36.0%, adequate in 25.1% and inadequate in 2.9%. The performance of reusable forceps declined with the number of uses. The reprocessing cost of reusable forceps for one biopsy session was calculated as ₩8,021. The adequacy of the sample was excellent for both forceps.

Conclusions

Disposable forceps showed excellent performance. Considering the reprocessing costs of reusable forceps, usage of disposable forceps with a low price should be considered.

Background/Aims

Cryotherapy is the therapeutic application for tissue ablation. Clinical applications of cryotherpy such as in pulmonology have increased. Until now, its development in gastroenterology has been insignificant. But, as clinical application such as mucosal ablation on Barrett's esophagus became possible, various applications have been developed. Therefore, it is important to make standards of tissue injury's extent in cryotherapy prior to clinical trial. We evaluated the tissue injury according to the application of cryoprobe with a pig model.

Methods

Cryoprobe was applied to several different segments of the esophagus and stomach for various lengths of time using various number of probe's contact in a pig model. After 48 hours, esophagus and stomach were harvested and histological tissue injury was assessed. The extent of tissue injury was decided by the injury of the deepest layer.

Results

Endoscopic application of cryoprobe on esophagus and stomach resulted in a dose-dependent injury: esophageal necrosis was limited to the submucosa after 10 seconds of cryotherapy, and extended to involve the transmural necrosis after over 15 seconds. Necrosis on stomach was extended to involve the transmural necrosis after over 20 seconds.

Conclusions

Positive relationship was seen between the duration and frequency of cryoprobe application and the extent of tissue injury.

AbstractAbstract PDFPubReaderePub
Background/Aims

Telemedicine is a convenient and efficient tool for remote education in various fields. The telemedicine system can also be used to educate doctors and medical students. The aim of our study was to establish the effectiveness of the telemedical system for use in a live endoscopic multichannel demonstration conference and to test the effectiveness and usefulness of a multicenter-based live endoscopic demonstration through live, interactive, high resolution video transmission using advanced networks and the digital video transport system (DVTS).

Methods

This study is a prospective multicenter pilot study. A live demonstration of an endoscopic submucosal dissection (ESD) and an endoscopic retrograde cholangiopancreatography (ERCP) using advanced network technology was performed.

Results

The DVTS successfully transmitted uncompressed, high-resolution, digital lectures with endoscopy video during a multichannel endoscopic live demonstration of ESD and ERCP over multiple advanced networks. The overall satisfaction rating when the endoscopic lecture demonstration was performed by combining DVTS was generally good.

Conclusions

We believe that a multicenter-based live endoscopic demonstration is a very effective conferencing method when using advanced networks and DVTS.

AbstractAbstract PDFPubReaderePub
Background/Aims

The placement of self expandable metal stent (SEMS) is one of the palliative therapeutic options for patients with unresectable malignant biliary obstruction. The aim of this study was to compare the effectiveness of a covered SEMS versus the conventional plastic stent.

Methods

We retrospectively evaluated 44 patients with unresectable malignant biliary obstruction who were treated with a covered SEMS (21 patients) or a plastic stent (10 Fr, 23 patients). We analyzed the technical success rate, functional success rate, early complications, late complications, stent patency and survival rate.

Results

There was one case in the covered SEMS group that had failed technically, but was corrected successfully using lasso. Functional success rates were 90.5% in the covered SEMS group and 91.3% in the plastic stent group. There was no difference in early complications between the two groups. Median patency of the stent was significantly prolonged in patients who had a covered SEMS (233.6 days) compared with those who had a plastic stent (94.6 days) (p=0.006). During the follow-up period, stent occlusion occurred in 11 patients of the covered SEMS group. Mean survival showed no significant difference between the two groups (covered SEMS group, 236.9 days; plastic stent group, 222.3 days; p=0.182).

Conclusions

The patency of the covered SEMS was longer than that of the plastic stent and the lasso of the covered SEMS was available for repositioning of the stent.

Clin Endosc 2012;45(1):84-88.   Published online March 31, 2012

AbstractAbstract PDFPubReaderePub
Background/Aims

Immediate postpolypectomy bleeding (IPPB) increases the procedure time and it may disturb performing a safe polypectomy. The purpose of this study is to investigate whether clipping before snare polypectomy of large pedunculated polyps is useful for the prevention of IPPB.

Methods

This is a single arm, pilot study. We enrolled patients with pedunculated colorectal polyps that were 1 cm in size or more from 4 university hospitals between June 2009 and June 2010. Clips were applied at the stalk and snare polypectomy was then performed. The complications, including IPPB, were investigated.

Results

Fifty six pedunculated polyps in 47 patients (Male:Female=36:11; age, 56±11 years) were included. The size of the polyp heads was 17±8 mm. Tubular adenoma was most common (57%). The number of clips used before snare polypectomy was 2±0.5. The procedure was successful in all cases. IPPB occurred in 2 cases (3.6%), and both of these were managed by additional clipping. Delayed bleeding occurred in another one case (1.8%), which improved with conservative treatment. No perforation occurred.

Conclusions

We suggest that clipping before snare polypectomy of pedunculated polyps may be an easy and effective technique for the prevention of IPPB, and this should be confirmed in large scale, prospective, controlled studies.

AbstractAbstract PDFPubReaderePub

As a rare complication of percutaneous endoscopic gastroscopy (PEG), a gastrocolocutaneous fistula may occur after PEG placement. This paper reports an interesting case which PEG tube unintentionally penetrated transverse colon during PEG. A 72-year-old female patient who suffered from medullary infarction underwent PEG procedure for enteral nutrition, and fecal materials were observed 6 days after the procedure. Transverse colon located in antero-superior site of stomach was observed through abdominal computed tomography, and also the wrong inserted tube was found through gastroscopy and colonoscopy. Endoscopic treatment for the fistula was performed by the use of hemo-clip and detachable snare, closure of the fistula was finally confirmed 6 days after the endoscopic procedure. Therefore, the gastrocolocutaneous fistula should be considered as one of the complications of PEG when fecal material is observed through PEG tube in a few days after PEG procedure and endoscopic treatment can be feasible in this case.

AbstractAbstract PDFPubReaderePub

Obstructive jaundice is very rarely caused by impaction of a pancreatic stone in the papilla. We report here on a case of obstructive jaundice with acute cholangitis that was caused by an impacted pancreatic stone in the papilla in a patient with chronic pancreatitis. A 48-year-old man presented with acute obstructive cholangitis. Abdominal computed tomography with the reconstructed image revealed distal biliary obstruction that was caused by a pancreatic stone in the pancreatic head, and there was also pancreatic ductal dilatation and parenchymal atrophy of the pancreatic body and tail with multiple calcifications. Emergency duodenoscopy revealed an impacted pancreatic stone in the papilla. Precut papillotomy using a needle knife was performed, followed by removal of the pancreatic stone using grasping forceps. After additional sphincterotomy, a large amount of dark-greenish bile juice gushed out. The patient rapidly improved and he has remained well.

AbstractAbstract PDFPubReaderePub

Colorectal cancer is rare in teenagers, especially without known risk factors. Colon cancer in young age is more likely to be diagnosed at advanced-stage, to present unfavorable tumor histology such as mucinous carcinoma, and poor outcome. We report a case of sporadic mucinous adenocarcinoma of the colon in a 19-year-old male patient without any risk factors. He complained of severe left abdominal pain that developed 1 month ago. He had a distended abdomen with severe tenderness on the left lower quadrant. A distal descending colon mass causing mechanical obstruction was observed on abdominal computed tomography. Emergency colonoscopy showed a large, fungating mass obstructing the lumen at 40 cm from the anal verge. Biopsy of the colonic mass suggested a mucinous adenocarcinoma. After decompression by colonic stent, the patient was transferred to the general surgery department for left hemicolectomy. The lesion was confirmed to be a mucinous adenocarcinoma (7.0×4.5 cm). For hereditary nonpolyposis colorectal cancer evaluation, immunohistochemical staining for MLH1 and MSH2 was normal. Reverse transcription polymerase chain reaction analysis did not detect microinstability in any of the markers tested. The patient had no familial history of cancer. Mucinous adenocarcinoma has high frequencies of poor differentiation, advanced tumor stage, loss of mismatch repair gene expression, and increased MUC2 expression. A mucinous histology is considerably more frequent in children and adolescent than in adults. Adequate invasive study is also necessary for young age patients.
