Drainage of gastric intramural abscesses using lumen-apposing metal stents

Abstract

BACKGROUNDGastric intramural abscesses are rare and often related to foreign body trauma. Owing to location and general nonresponse to broad-spectrum antimicrobial therapy, endoscopic drainage is often used.To date, there are few cases in the literature. Prior methods described for endoscopic drainage include needle-knife fenestration 1-3 and pigtail catheter placement. 4 Recently, lumen-apposing metal stents (LAMSs) were designed for drainage of pancreatic fluid collections and are recommended as a first-line alternative to plastic stents. 5 However, the use of LAMSs in drainage of a gastric intramural abscess has not previously been reported.This video case presentation highlights an 83-year-old man with a history of diabetes mellitus and prostate carcinoma that had previously been resected and treated with taxotere. The patient presented with abdominal pain, nausea, and intermittent fever. He was found to have a leukocytosis, and CT of the abdomen/pelvis with intravenous contrast demonstrated a large gastric intramural ab-
