Background
/Aims: Frequent bleeding after endoscopic resection (ER) has been reported in patients with end-stage renal disease (ESRD). We aimed to evaluate the association and clinical significance of bleeding with ER in ESRD patients on dialysis.
Methods
Between February 2008 and December 2018, 7,571 patients, including 47 ESRD patients on dialysis who underwent ER for gastric neoplasia, were enrolled. A total of 47 ESRDpatients on dialysis were propensity score-matched 1:10 to 470 non-ESRD patients, to adjust for between-group differences in variables such as age, sex, comorbidities, anticoagulation use, tumor characteristics, and ER method. Matching was performed using an optimal matching algorithm. For the matched data, clustered comparisons were performed using the generalized estimating equation method. Medical records were retrospectively reviewed. Frequency and outcomes of post-ER bleeding were evaluated.
Results
Bleeding was more frequent in the ESRD with dialysis group than in the non-ESRD group. ESRD with dialysis conferred a significant risk of post-ER bleeding (odds ratio, 6.1; 95% confidence interval, 2.7–13.6; p<0.0001). All post-ER bleeding events were controlled using endoscopic hemostasis except in 1 non-ESRD case that needed surgery.
Conclusions
ESRD with dialysis confers a bleeding risk after ER. However, all bleeding events could be managed endoscopically without sequelae. Concern about bleeding should not stop endoscopists from performing ER in ESRD patients on dialysis.

A Case of Primary Small Bowel Melanoma Diagnosed by Single-Balloon Enteroscopy
Jun Young Shin, In Suh Park, Byoung Wook Bang, Hyung Kil Kim, Yong Woon Shin, Kye Sook Kwon

AbstractAbstract PDFPubReaderePub
Although metastasis from cutaneous malignant melanoma to the small intestine is not uncommon, primary small bowel melanoma (SBM) is extremely rare. This case report describes a rare case of primary SBM, diagnosed by single-balloon enteroscopy. A 74-year-old man presented with recurrent melena. Upper endoscopy and colonoscopy were unremarkable. Abdominal computed tomography (CT) revealed an ileal mass with ileo-ileal intussusception. Subsequent single-balloon enteroscopy identified an ileal tumor, which was histologically diagnosed as melanoma. Extensive clinical examination did not reveal any primary cutaneous lesions. To the best of our knowledge, this is the first case of primary SBM in South Korea.

Twenty-Second versus Sixty-Second Dilation Duration in Endoscopic Papillary Balloon Dilation for the Treatment of Small Common Bile Duct Stones: A Prospective Randomized Controlled Multicenter Trial
Byoung Wook Bang, Tae Hoon Lee, Tae Jun Song, Joung-Ho Han, Hyun Jong Choi, Jong Ho Moon, Chang-Il Kwon, Seok Jeong

Background/Aims

Endoscopic papillary balloon dilation (EPBD) has been advocated as an alternative therapy to endoscopic sphincterotomy for the treatment of common bile duct (CBD) stones. However, there is no established consensus on the optimal balloon dilation duration (BDD). We prospectively evaluated the efficacy and post-endoscopic retrograde cholangiopancreatography (ERCP) complications between the 20- and 60-second EPBD groups.

Methods

A total of 228 patients with small CBD stones (≤12 mm) were randomly assigned to undergo EPBD with a 20- or 60-second duration at six institutions. We evaluated baseline patient characteristics, endoscopic data, clinical outcomes, and procedure-related complications. In addition, we analyzed risk factors for postprocedural pancreatitis.

Results

CBD stones were removed successfully in 107 of 109 patients (98.1%) in the 20-second group and in 112 of 119 patients (94.1%) in the 60-second group (p=0.146). Post-ERCP pancreatitis developed in seven patients (6.4%) in the 20-second group and nine patients (7.5%) in the 60-second group (p=0.408). In multivariate analysis, contrast dye injection into the pancreatic duct is a significant risk factor for post-EPBD pancreatitis.

Conclusions

Based on the data showing that there were no significant differences in safety and efficacy between the two BDD groups, 20 seconds of BDD may be adequate for treatment of small CBD stones with EPBD.

A Case of Esophageal Fibrovascular Polyp That Induced Asphyxia during Sleep
Jin-Seok Park, Byoung Wook Bang, Junyoung Shin, Kye Sook Kwon, Hyung Gil Kim, Yong Woon Shin, Suk Jin Choi
Clin Endosc 2014;47(1):101-103.   Published online January 24, 2014
DOI: https://doi.org/10.5946/ce.2014.47.1.101
AbstractAbstract PDFPubReaderePub

Esophageal fibrovascular polyps are rare, benign, submucosal tumors of the upper digestive tract that usually have an indolent course until the lesion attains a very large size. The most frequent complaints associated with these tumors include dysphagia and foreign body sensation. However, a long pedunculated polyp can regurgitate into the pharynx or oral cavity and cause asphyxia and sudden death if the larynx is occluded. We describe the case of a 51-year-old man who experienced snoring and occasional asphyxia during sleep. Upper endoscopy was performed, which indicated the presence of a pedunculated esophageal polyp that regurgitated into the vocal cords. The polyp was removed using a polypectomy snare and was confirmed to be a fibrovascular polyp based on pathologic examination findings. Three months after the excision of the polyp, the patient was found to be doing well without any further occurrence of asphyxia or sleep disturbances.

Peroral Endoscopic Myotomy for Treating Achalasia in an Animal Model: A Feasibility Study
Byoung Wook Bang, Young Chul Choi, Hyung Gil Kim, Kye Sook Kwon, Yong Woon Shin, Don Haeng Lee, Joon Mee Kim
Clin Endosc 2013;46(1):54-58.   Published online January 31, 2013

AbstractAbstract PDFPubReaderePub
Background/Aims

Laparoscopic Heller myotomy with antireflux procedure is considered to be a standard treatment for achalasia. Recently, peroral endoscopic myotomy (POEM) was developed and performed on patients with achalasia. However, there is no report on POEM use in South Korea. The aim of this study was to evaluate the technical feasibility of POEM in a porcine model.

Methods

POEM was performed on two mini pigs. We performed upper endoscopy under general anesthesia. A submucosal tunnel was created and the circular muscle layer was incised using several knives. The mucosal entry was closed using resolution clips. We performed a follow-up endoscopy and sacrificed the pigs 2 weeks after the POEM. The myotomy site was evaluated grossly and histologically.

Results

POEM was successfully performed on the two mini pigs. No injuries to any abdominal or mediastinal structures occurred. Two weeks after the POEM, the esophageal mucosa healed without any endoscopic evidence of complications. Necropsy revealed that the circular muscle layer was completely lost and replaced with fibrotic tissue.

Conclusions

We found that POEM is a technically feasible method which can be performed on an animal model. However, to ensure safe use on patients with achalasia, further studies on technical methods and long-term follow-up examinations are required.

Two Cases of Ileal Dieulafoy Lesion with Massive Hematochezia Treated by Single Balloon Enteroscopy
Young Chul Choi, Sang Hyun Park, Byoung Wook Bang, Kye Sook Kwon, Hyung Gil Kim, Yong Woon Shin
Clin Endosc 2012;45(4):440-443.   Published online November 30, 2012
DOI: https://doi.org/10.5946/ce.2012.45.4.440
AbstractAbstract PDFPubReaderePub

Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It can be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. Ileal Dieulafoy lesion is hard to recognize due to inaccessibility and normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic and therapeutic approaches including enteroscopy have recently been performed for small bowel bleeding. We report two cases of massive ileal Dieulafoy lesion bleeding diagnosed and treated successfully by single balloon enteroscopy with a review of the literature.
