Modified technique of antegrade continence enema using a stapling device.

Abstract

PURPOSE: We present a stapling technique for constructing an antegrade continence enema (ACE) conduit that is helpful in cases of insufficient appendiceal luminal length or when a concomitant appendiceal Mitrofanoff stoma is required. MATERIALS AND METHODS: In 6 patients with a mean age of 9.5 years who required an ACE procedure the cecum was tubularized in continuation with the orthotopic appendix at its base, using a stapling device to construct an ACE conduit. The tubularized segment was imbricated with permanent suture material. In 3 cases appendiceal length after tubularization was sufficient to allow splitting for the concomitant creation of an appendiceal Mitrofanoff stoma. RESULTS: Patients have been followed an average of 16.5 months. Stomal continence was achieved in all cases as well as reliable catheterization of the appendiceal cecostomy in 6 and the Mitrofanoff conduit in 3. CONCLUSIONS: This modification of the ACE procedure with cecal tubularization in continuation with the appendix using a stapling device is an excellent approach in cases of inadequate appendiceal length. It successfully creates a catheterizable stoma with a reliable flap valve continence mechanism. The complex reconstructive procedure is simplified by eliminating the need to use tapered small intestine, while allowing the creation of a concomitant appendiceal Mitrofanoff stoma as necessary.
