Recurring enteric peritonitis associated with non-perforating colon carcinoma.
Peritonitis of enteric origin may occur during treatment with peritoneal dialysis due to visceral perforation or injury or, in the absence of perforation, due to transmural migration of enteric bacteria across the bowel wall into the peritoneal cavity. To the best of our knowledge, peritonitis has not previously been reported associated with carcinomatous colon polyp in the absence of bowel wall perforation. We describe the case of a 31-year-old female who experienced recurring episodes of enteric peritonitis associated with a clinically occult adenocarcinoma of the colon, without having any other known risk factors for peritonitis. A 15 mm carcinomatous polyp was not visible on CT scan but was found at colonoscopy with polypectomy. She proceeded to transverse colectomy; the resected colon showed no evidence of bowel wall perforation. This case demonstrates that a non-perforating carcinomatous polyp of the colon may predispose to enteric peritonitis in the setting of peritoneal dialysis, and it emphasizes the importance of making an aggressive search for underlying pathology, in patients who present with recurring enteric peritonitis or unusual presentations of enteric peritonitis.
