# A Case of Perforated Peritonitis Caused by the Migration of a Single‐Puncture Gastric Wall Fixation Device Following Percutaneous Endoscopic Gastrostomy

## TL;DR

An elderly man developed peritonitis after a medical device used in a stomach procedure migrated and caused a stomach wall tear.

## Contribution

This is the first reported case of peritonitis caused by T-fastener migration outside the gastric wall.

## Key findings

- A single-puncture gastric wall fixation device migrated and caused gastric perforation.
- The patient required emergency surgery due to acute peritonitis six days after the procedure.

## Abstract

We report an uncommon case of perforated peritonitis resulting from the migration of a single‐puncture gastric wall fixation device following percutaneous endoscopic gastrostomy. An 83‐year‐old male developed acute peritonitis 6 days post‐procedure, requiring emergency surgery. One fixation device was found embedded in the abdominal wall, and gastric perforation was identified. To our knowledge, this is the first reported case of peritonitis caused by T‐fastener migration outside the gastric wall.
