AbstractWe report a case of tension pneumothorax, which occurred secondary to colonic perforation during a colonoscopy. The patient was a 77-year-old woman in whom acute respiratory decompensation developed suddenly during a diagnostic colonoscopy for iron deficiency anemia. We diagnosed bilateral pneumothoraces, tension pneumothorax, pneumomediastinum, pneumoperitoneum, and emphysema of the face, neck, and chest. At laparotomy, a posterior colonic perforation was identified at the site of an ileocolic anastomosis performed 3 years earlier. We performed a primary repair and the patient was discharged from hospital 12 days later. Although diagnostic colonoscopy-induced intestinal perforation is rare, it is the most common and serious complication associated with this procedure. Occasionally, air spreads from the retroperitoneum into continuous tissue planes and decompresses into the adjacent structures. To our knowledge, this is the first report of two unique manifestations of diagnostic colonoscopy-induced intestinal perforation: tension pneumothorax and perforation at the site of a previous anastomosis. Both of these conditions should be considered in the event of acute respiratory failure in the endoscopy suite.
