Tension Pneumoperitoneum Following Upper Gastrointestinal Endoscopy

Tension pneumoperitoneum (TPP) is a potentially lethal complication of numerous iatrogenic procedures, including upper gastrointestinal (UGI) endoscopy. This report details the case of a 78-year-old woman with abdominal pain who developed TPP and cardiac arrest after undergoing UGI endoscopy. She was successfully resuscitated with needle decompression. The patient underwent laparoscopic gastrorrhaphy for gastric ulcer perforation. Unfortunately, the patient developed a disseminated intravascular coagulation and multiple-organ failure, and died on postoperative day 5.
