A Case of a Removal of Pyloric Stent That Was Partially Embeded in the Mucosa after Temporary Stenting for the Benign Pyloric Stenosis and It Was Removed Using Argon Plasma Coagulation / 대한소화기내시경학회지

Generally, self expandable metallic stents (SEMSs) are widely used for the treatment of malignant gastrointestinal stenosis due to their effectiveness and low complication rate. On the contraty, balloon dilatation or Bougie dilatation is commonly used for treating benign gastrointestinal stenosis as non-invasive methods. However, their such complications such as recurrence, hemorrhage and perforation are problematic when these dilation techniques are used. Temporary placement of a SEMS in a benign gastric outlet obstruction is expected to be a promising therapeutic modality despite of several major complications such as migration. Rarely, stent removal can, on rare occasions, be difficult or cause bleeding or perforation when the stent is embeded in the mucosa due to mucosal hyperplasia at the tips of the stent. We report here on a case of a stent, partially embeded in the mucosa after temporary stenting for treating a benign pyloric stenosis, which was successfully removed using argon plasma coagulation.

A Case of Endoscopic Stenting for Anastomotic Leakage after Total Gastrectomy / 대한소화기내시경학회지

Anastomotic leakage after gastrectomy has significant morbidity and mortality, and the mortality rate has been reported to be over 60%. There have been very few reports concerning endoscopic stenting for the management of anastomotic leakage. Successful treatment of anastomotic leakage with covered self-expanding metallic stents (stent) has recently been reported. A 62-year-old man with melena was diagnosed with advanced gastric cancer and he underwent total gastrectomy. At the 3rd day after surgery, anastomotic leakage was found by an upper gastrointestinal series (UGI). He underwent laparoscopic primary repair on the 5th day after surgery. The leakage resumed thereafter. At the 12th day after the primary repair, the leakage was successfully managed by stent insertion and the patient improved thereafter. At the 11th week after stent insertion, the stent was removed without complications and the leakage was completely closed. At 1 year after stent removal, no stricture has been found on the anastomosis site. We report here on a case of anastomotic leakage after gastrectomy, and this was completely managed by stent insertion.

A Case of Small Bowel Bleeding Treated by Single Balloon Enteroscopy in a Patient on Maintenance Hemodialysis / 대한신장학회지

Anemia is a common complication of hemodialysis. It reduces the quality of life and is recognized as adverse risk factor. The cause of anemia in CKD (chronic kidney disease) include lack of erythropoietin, gastrointestinal (GI) bleeding, hypothyroidism, hidden infection, and blood loss in hemodialysis. GI bleeding is not unusual complication in patient on maintenance hemodialysis, caused by uremia, medicine (NSAIDS, antiplatelet agents, anticoagulants), angiodysplasia, and ulcer. In CKD patients, GI bleeding is found in various sites over the whole bowel. Small bowel bleeding is one of the most common causes of obscure GI bleeding and constitutes 2-10% of all GI bleeding. Regarding the small bowel bleeding, diagnosis and treatment are much improved recently with the help of wireless capsule endoscopy and double or single balloon enteroscopy. We report a case of GI bleeding due to erosion of small bowel, which was diagnosed and treated with the single-balloon enteroscopy in patients on maintenance hemodialysis.
