Abstract PDF: Background
/Aims: The ingestion of foreign bodies in the upper gastrointestinal tract usually happens as a result of accidental swallowing, and rarely produces symptoms. Although most foreign bodies are eliminated spontaneously, 10∼20% of cases need treatment with endoscopy. We evaluated the role of endoscopy for removing foreign bodies from the upper gastrointestinal tract. Methods: We analyzed one hundred and thirty-nine cases of foreign bodies in the upper gastrointestinal tract which were endoscopically treated at Chungnam National University Hospital from January 2001 to July 2004. Results: Patients' age ranged from 6 months to 96 years old (mean 36.0 years old). The ratio of males to females was 1.2：1. The common foreign bodies included coins (29 cases) and fish bones (23 cases), animal bones (19 cases), and stones (15 cases) follows in order. The most common location was the esophagus (79.9%). In most cases (73.4%), the foreign body was removed using an alligator tooth and a grasping forceps. Twenty-eight among one hundred and thirty-nine patients had a co-morbid condition, such as esophageal disease, diabetes mellitus, hypertension, stomach cancer, or a psychiatric disorder. Conclusions: Endoscopic removal is a very powerful and useful method for removing foreign bodies from the upper gastrointestinal tract. Nevertheless, a simpler and more efficient endoscopic equipment is required. (Korean J Gastrointest Endosc 2005;31:135⁣139)

The Usefulness of Capsule Endoscopy in Patients with Obscure Gastrointestinal Bleeding: Hyun Jeong Kim, M.D., Chan Sup Shim, M.D., Sang Ho Lee, M.D., In Seop Jung, M.D., Su Jin Hong, M.D., Chang Bum Ryu, M.D., Jin Oh Kim, M.D., Joo Young Cho, M.D., June Seong Lee, M.D., Moon Sung Lee, M.D. and Boo Sung Kim, M.D.; Korean J Gastrointest Endosc 2005;31(3):140-146. Published online September 30, 2005

Abstract PDF: Background
/Aims: Obscure gastrointestinal bleeding (OGIB) is defined as recurrent bleeding for which no source has been identified by routine endoscopic and contrast studies. This study was performed to determine the utility of capsule endoscopy in patients with OGIB. Methods: This retrospective study included 21 patients with GIB which were not identified by esophagogastroduodenoscopy and colonoscopy. Those were sixteen patients with overt OGIB (including 6 ongoing overt bleeding) and five with occult OGIB. All underwent capsule endoscopy with Given M2A video capsule system. Results: Definite bleeding of small intestine were identified in 9 of 21 patients (42.9%) and 8 of 9 patients presenting as overt OGIB (50.0%, 8/16). Additionally, 5 of 6 patients with ongoing bleeding on the day of capsule endoscopy were found to have the lesion in small intestine (83.3%, 5/6). Ulcers were found in 6 patients, diverticulitis in 2 patients, and a tumor in 1 patients. Conclusions: Capsule endoscopy, providing a good visualization of small intestine, is safe and well tolerated. Capsule endoscopy is an useful diagnostic tool for OGIB, especially for ongoing overt bleeding, and can guide the subsequent therapy and expand diagnostic yield in OGIB.

Published online September 30, 2005

Abstract PDF: Background
/Aims: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is a technique used to distinguish benign and malignant pancreatic mass histologically. The aim of this study was to determine the value and safety of EUS-FNA for the differential diagnosis of pancreatic solid mass. Methods: The records of forty patients (M：F=24：16, median age: 56 yr) who underwent EUS-FNA for the diagnosis of pancreatic solid masses between October 2003 and July 2004 were analyzed. Histological findings obtained by EUS-FNA were compared with the final diagnosis. The sensitivity, specificity, overall diagnostic accuracy, and the rate of complication of EUS-FNA were analyzed. Results: The sites of the lesions were as follows: pancreatic head, n=20 (50%); body, n=10 (25%); tail, n=7 (18%); multifocal, n=3 (8%). The sensitivity, specificity, accuracy and negative predictive values were 71%, 78%, 73%, and 64%, respectively. The diagnostic accuracy was 90% in body lesions, however 65% in head lesions. Transient abdominal pain occurred in one patient (3%) after the procedure; however, there was no case of severe complication. Conclusions: EUS-FNA is shown to be an effective and safe procedure for establishing a tissue diagnosis in patients with solid pancreatic masses. (Korean J Gastrointest Endosc 2005;31:147⁣154)

Clinical Application and Safety of Endoscopic Pancreatic Sphincterotomy in 339 Cases: Hyun Young Son, M.D., Sung Koo Lee, M.D., Moon Hee Song, M.D., Ji Min Han, M.D., Eun Kwang Choi, M.D., Jong Cheol Kim, M.D., Sang Soo Lee, M.D., Dong Wan Seo, M.D. and Myung-Hwan Kim, M.D.; Korean J Gastrointest Endosc 2005;31(3):155-160. Published online September 30, 2005

Abstract PDF: Background
/Aims: Endoscopic pancreatic sphincterotomy (EPST) has been performed more frequently in recent years. However, it is less widely practiced than biliary sphincterotomy due to lack of firm scientific data regarding its indication and safety. The aims of this study are to evaluate EPST with regard to indications, complications, and safety. Methods: We retrospectively reviewed and analyzed the results of EPST performed in three hundred thirty nine patients from January 2000 to April 2004. Results: Complications occurred in 37 patients (10.7%) which included pancreatitis, hemorrhage, perforation, cholangitis, sepsis, and stenosis of sphincterotomy site. They were successfully managed by medical treatment. No mortalities were reported. Conclusions: EPST is a relatively safe procedure in various pancreatic diseases. Incidence of long-term complications awaits further investigations. EPST enlarges our endotherapeutic armamentarium and deserves additional evaluation. (Korean J Gastrointest Endosc 2005;31:155⁣160)

Endoscopic Mucosal Resection in Early Gastric Cancer Involving Duodenum: Jee Hyun Park, M.D., Dong In Kim, M.D., Sung Jo Bang, M.D., In Du Jeong, M.D., Jung Woo Shin, M.D., Neung Hwa Park, M.D., Yang Won Nah, M.D.*, Jae Hee Suh, M.D.^† and Do Ha Kim, M.D.; Korean J Gastrointest Endosc 2005;31(3):166-170. Published online September 30, 2005

Abstract PDF: It is difficult to perform endoscopic mucosal resection (EMR) in case of early gastric cancer involving duodenal bulb. To achieve complete resection, we applied a new method: that is, EMR with an insulation-tipped diathermic knife (IT knife) was peformed by the retroflexion of endoscope in the bulb. This method was tried in 4 patients. For the antral side of the tumor, EMR was done using a needle knife or IT knife. The duodenal side of the tumor was resected by IT knife with the retroflexion of endoscope in the bulb. The complete resection was performed in 2 patients, an incomplete resection in one patient, and the laparoscopic subtotal gastrectomy was performed in the remaining one patient because reconstruction of partitional resection was very difficult and adenocarcinoma was found to involve the muscularis mucosa. We think that EMR with IT knife by endoscopic retroflexion in the bulb is effective for some cases of early gastric cancer involving the duodenal bulb. (Korean J Gastrointest Endosc 2005;31:166⁣170)

A Case of Endoscopic Polypectomy Using a Hand-Made Detachable Snare Made of Nylon Fishing Line: Jong Chun Nah, M.D., Jong Sung Lee, M.D., Young Kwan Kim, M.D., Jin Kwang Lee, M.D., Seong Eun Kim, M.D., Soo Hyung Ryu, M.D., Jung Whan Lee, M.D.,You Sun Kim, M.D. and Jeong Seop Moon, M.D.; Korean J Gastrointest Endosc 2005;31(3):185-188. Published online September 30, 2005

Abstract PDF: Hemorrhage is the most common complication of polypectomy. Though most bleeding stops spontaneously and can be managed with conservative therapies, some may necessitate intensive therapies. The detachable snare was firstly introduced in 1986. It has been reported that the use of detachable snare can effectively prevent both immediate and delayed bleeding. The detachable snare has been reformed, and now a commercial article is used in practice. But, it is expensive and cannot be used in larger polyps measuring over its fixed size of loop. A hand-made detachable snare made of nylon fishing line was introduced to prevent postpolypectomy bleeding in 2003. We have further improved it and experienced a case of successful removal of a large colonic polyp using our hand-made snare. The hand-made detachable snare is inexpensive and seems to be practical in ligating the polyp regardless of its size. (Korean J Gastrointest Endosc 2005;31:185⁣188)

Published online September 30, 2005

Abstract PDF: Colonoscopy is a relatively safe procedure with few complications. However, it may be accompanied with complications such as bleeding, perforation and, rarely, acute appendicitis. Acute appendicitis occurs when the appendiceal opening is obstructed by lymphoid hyperplasia, fecalith or foreign materials. In case of late detection, acute appendicitis can results in perforation and panperitonitis. Therefore early diagnosis and proper management is mandoctory. We experienced a 70-year-old female patient who visited for abdominal pain and tenderness after the diagnostic colonoscopy and was found to develop acute appendicitis. Herein, we report the case with the review of literatures. (Korean J Gastrointest Endosc 2005;31:189⁣192)

A Case of Acute Appendicitis following Diagnostic Colonoscopy: Yeong Seop Yun, M.D., Oh Young Lee, M.D., Ho Yong Park, M.D., Sung Hee Han, M.D., Sun Young Yang, M.D., Dae Won Jun, M.D., Yong Chul Jeon, M.D., Dong Soo Han, M.D., Ho Soon Choi, M.D. and Byung Chul Yoon, M.D.; Korean J Gastrointest Endosc 2005;31(3):189-192. Published online September 30, 2005

Abstract PDF: Colonoscopy is a relatively safe procedure with few complications. However, it may be accompanied with complications such as bleeding, perforation and, rarely, acute appendicitis. Acute appendicitis occurs when the appendiceal opening is obstructed by lymphoid hyperplasia, fecalith or foreign materials. In case of late detection, acute appendicitis can results in perforation and panperitonitis. Therefore early diagnosis and proper management is mandoctory. We experienced a 70-year-old female patient who visited for abdominal pain and tenderness after the diagnostic colonoscopy and was found to develop acute appendicitis. Herein, we report the case with the review of literatures. (Korean J Gastrointest Endosc 2005;31:189⁣192)

Tubular Adenoma of the Common Bile Duct: Endoscopic Diagnosis and Treatment: Jin Hyuck Chang, M.D., Dong Ki Lee, M.D., Tae Woong No, M.D., Min Su Kim, M.D., Kuen Man Lee, M.D., Se Joon Lee, M.D., Sang In Lee, M.D. and Seok Woo Yang, M.D.*; Korean J Gastrointest Endosc 2005;31(3):193-197. Published online September 30, 2005

Abstract PDF: Biliary adenoma of the common bile duct is a rare disease found in biliary tract encounterd in biliary mass lesion, and it is difficult to differentiate from their malignant counterparts. Symptoms and signs of these tumors can mimic choleliathiasis and malignant tumors. Therefore, this tumor is rarely diagnosed preoperatively. In addition, there has been no reported case of a tubular adenoma of the common bile duct in Korea, until recently. We experienced a case of tubular adenoma of the common bile duct, which was diagnosed and partially resected by percutaneous transhepatic cholangioscopy. The patient was a 84-year-old male who showed abnormal liver function test. Abdominal ultrasonography showed a dilated common bile duct, and a soft tissue was observed on endoscopic retrograde cholangiography. This was initially thought as a stone, but it became partially detachable from the common bile duct during an endoscopic retrograde cholangioscopic basket removal. The mass lesion was partially resected by a percutaneous transhepatic cholangioscopic snare. This resected tissue was confirmed as a tubular adenoma. (Korean J Gastrointest Endosc 2005;31:193⁣197)

A Case of Hemobilia Caused by Chronic Acalculous Cholecystitis: Hyun A Oh, M.D., Tae Neyun Kim, M.D., Eun Ju Lee, M.D., Hyung Chul Lee, M.D., Jun Hwan Kim, M.D., Byung Ik Chang, M.D. and Heon Ju Lee, M.D.; Korean J Gastrointest Endosc 2005;31(3):198-203. Published online September 30, 2005

Abstract PDF: Hemobilia is a status of bleeding into the biliary tract and occurs when the communication between the biliary tract and blood vessels was injured. Almost all the hemobilia orginated in the gallbladder were related to gallstones and rarely it was reported to be associated with acalculous cholecystitis. A 61-year-old man visited due to continuous right upper quadrant pain and endoscopy revealed oozing blood around the ampulla of Vater. Eighteen days later, laparoscopic cholecystectomy was performed and pathologic examination of the resected gallbladder disclosed acalculous cholecystitis and no stone was found. We report a case of hemobilia with acalculous cholecystitis. (Korean J Gastrointest Endosc 2005;31:198⁣203)

A Case of Intraductal Papillary Mucinous Tumor of the Pancreas with Scant Mucin Production: Won Jae Yoon, M.D., Jun Kyu Lee, M.D., Kwang Hyuck Lee, M.D., Ji Kon Ryu, M.D., Yong-Tae Kim, M.D. and Yong Bum Yoon, M.D.; Korean J Gastrointest Endosc 2005;31(3):204-208. Published online September 30, 2005

Abstract PDF: Intraductal papillary mucinous tumors of the pancreas (IPMT) commonly produce large amount of mucin. However, rare cases of IPMTs with scant mucin production were reported. Although such tumors seem to produce little or no mucin at all, immunohistochemical staining usually reveals the histologic evidence of mucin production. We report a case of intraductal papillary mucinous tumor of the pancreas with scant mucin production. (Korean J Gastrointest Endosc 2005;31:204⁣209)
