Tension pneumoperitoneum as a nontraumatic complication of upper gastrointestinal endoscopy

One More ‘T’ for the Mnemonic of the Management of Pulseless Electrical Activity: Tension Pneumoperitoneum

The approach in Advanced Cardiac Life Support provided by the American Heart Association and the European Resuscitation Council guidelines for the management of pulseless electrical activity emphasizes on the search of reversible causes. Tension pneumoperitoneum is an uncommon surgical emergency encountered in the accident and emergency department. We report a case of pulseless electrical activity secondary to tension pneumoperitoneum in an elderly woman. Restoration of spontaneous circulation was immediately achieved after needle decompression. The management of tension pneumoperitoneum is discussed.

Tension pneumoperitoneum: a rare complication of upper gastrointestinal endoscopy

INTRODUCTION

Tension pneumoperitoneum is defined as the massive accumulation of air in the peritoneal cavity, which results in a sudden increase in intraabdominal pressure. Various iatrogenic procedures are responsible for this complication. We herein report a case of tension pneumoperitoneum resulting from upper gastrointestinal endoscopy.

CASE DESCRIPTION

A 45-y-old man was referred to our department because of melena. Esophagogastroscopy was unsuccessful because of failure to inflate the stomach, and sudden abdominal distension was noted immediately after the procedure. The hemodynamic status of the patient was compromised, and the imminent collapse was prevented with emergent needle paracentesis. Decompression of the abdominal cavity restored vital signs to normal allowing definitive surgical treatment.

DISCUSSION

Upper gastrointestinal endoscopy is a rare cause of this life-threatening complication. The combination of acute abdominal distension with hemodynamic instability following endoscopic procedures should raise suspicion of tension pneumoperitoneum. Needle decompression is life-saving and should be performed instantly upon recognition of this condition.

Tension pneumoperitoneum after heart-lung transplantation

Tension pneumoperitoneum is a medical emergency. We report 2 cases in which tension pneumoperitoneum occurred after heart-lung transplantation and was related to positive-pressure ventilation and a transdiaphragmatic passage of omentum used to wrap the airway anastomosis. Management in these patients was targeted toward decompression of intraperitoneal air with percutaneous needle or tube placement without exploratory laparotomy, and tube thoracostomy for the concomitant pneumothorax.
