Acute abdomen and Clostridium difficile colitis: still a lethal combination

With the steadily prevalent appropriate and inappropriate use of antimicrobial agents, Clostridium difficile colitis has continued to be noticed as a common problem in hospitalized patients. The aim of this communication is to highlight a subset of C. difficile colitis patients who presented with an acute abdomen.

This is a retrospective study of 10 patients who underwent laparotomy for an 'acute abdomen' with an intraoperative or postoperative diagnosis of C. difficile colitis.

All patients received antibiotics (mean 9.5 days) for other illnesses. The mean APACHE II score was 18.8 (range 8-25) and the mortality rate was 80%. Two patients had colostomies created. One patient underwent a subtotal colectomy, and another underwent a Hartmann procedure; the rest had a nontherapeutic procedure.

We conclude that C. difficile colitis presenting as an 'acute abdomen' still represents a lethal entity. Patients who present with an 'acute abdomen', with a history of recent or current antibiotic intake, and without findings which mandate an exploration should have C. difficile colitis urgently excluded. Timely diagnosis of C. difficile colitis through bedside sigmoidoscopy or a CT scan could spare the critically ill patient an unneccessary and risky operation. Furthermore, if laparotomy is subsequently needed then having a preoperative diagnosis of C. difficile colitis will allow appropriate surgical therapy to be implemented.
