Fatal Colonic Explosion During Colonoscopic Polypectomy
A patient is described who sustained the first reported colonic explosion during colonoscopic polypectomy. Mannitol solution was used for bowel preparation, and the colon was completely clean. During snare removal of a cecal polyp using high-frequency current a loud explosion occurred. In spite of emergency surgery with transfusion of 45 units of blood, uncontrollable hemorrhage persisted from multiple bleeding points, and the patient died.
