Short-term Outcomes of Chait Trapdoor for Antegrade Continence Enema in Adults

Objective To examine our short-term experience of antegrade continence enema (ACE) delivered via a Chait Trapdoor (Cook Medical, Bloomington, IN) in adults with intractable neurogenic bowel. Methods We performed a retrospective review at the Universities of Utah and Minnesota of 15 patients with Chait Trapdoor placed for the purpose of ACE from 2011 to 2013. Our primary outcome was continued utilization of the Chait Trapdoor. Secondary outcomes included volume of ACE used and time to produce a bowel movement. Results All patients had neurogenic bowel refractory to conventional bowel regimen. Mean follow-up was 6 months (range, 1-17 months). Thirteen patients had the Chait Trapdoor placed in the splenic flexure and 2 had it placed in the cecum. Of the 15 patients, 12 (80%) were still using the Chait Trapdoor at last follow-up. A median of 425 mL (range, 120-1000 mL) of fluid was used to produce a bowel movement in 5-120 minutes. Two patients developed postoperative wound infections, requiring return to the operating room (Clavien IIIb). Long-term complications included 5 patients with a dislodged tube requiring replacement by interventional radiology and 2 patients with local cellulitis. Two patients had the Chait Trapdoor moved to a new location to improve efficacy. Conclusion Although the revision, removal, and complication rates were high, 80% of the patients were satisfied with the function and continued to use the Chait Trapdoor. The volume of irrigation required for ACE and the time it takes to produce a bowel movement vary significantly between patients.
