Percutaneous endoscopic gastropexy for postcolostomy internal hernia of the stomach: a rare case report

Colostomy-associated internal hernia is a rare postoperative complication, and gastric incarceration through the lateral defect between a lifted sigmoid colostomy and the abdominal wall is exceedingly uncommon, with only three previously reported cases, all of whom were surgically managed for preventing recurrence. We report a rare case of gastric incarceration following sigmoid colostomy in which percutaneous endoscopic gastropexy was performed as a minimally invasive strategy for recurrence prevention. A 59-year-old male presented with vomiting 11 months after undergoing Hartmann's procedure with an intraperitoneal sigmoid colostomy for sigmoid volvulus. Computed tomography revealed gastric herniation through the lateral defect, causing significant gastric distension. Symptoms resolved following nasogastric decompression, and spontaneous hernia reduction was confirmed. Percutaneous endoscopic gastropexy was subsequently performed without complications. The patient had an uneventful recovery and remained recurrence free at the 4-month follow-up.
