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.

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

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

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.


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.


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.


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.

Case Report
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
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.
