A Case of Zenker Diverticulum Treated by Transparent Cap and Needle Knife / 대한내과학회지

Zenker diverticulum is a rare condition with a reported prevalence of 0.01% to 0.11% in the general population. Challenges that can arise when treating a Zenker diverticulum through flexible endoscopy include maintaining a stable position and avoiding hemorrhage or perforation. Nevertheless, this approach is associated with less morbidity and a shorter hospital stay than conventional treatment consisting of open surgery or rigid endoscopic treatment with diverticuloscopy. We report a case of transparent cap-assisted flexible endoscopic septoplasty using a needle knife.

A Case of Gastric Bezoar Treated with a Distal Attachment Device / 대한소화기내시경학회지

Bezoars are collection of indigestible materials in the gastrointestinal tract. Many endoscopic techniques for removal of bezoars have been reported recently, but these methods need much equipment. We treated a gastric bezoar with a distal attachment device easily available for an endoscope. A 74-year-old man with a history of diabetes mellitus was admitted to hospital with hematemesis. On the second endoscopic examination, a gastric bezoar (6x4x4 cm) was detected in the stomach. Then, using a distal attachment device, we injected Coca-Cola directly into the bezoar by an injector. With tension force, the bezoar was easily broken due to the impulse of the distal attachment device. The endoscopic technique used in our case can be easily performed and has fewer complications compared to those of other techniques. Therefore, we report here on this new treatment modality that uses a distal attachment device.
