Coming face to face with the stenotic MACE-combined Maceoscopy and colonoscopy (the rendez-vous procedure): a preliminary report

Objective The aim of our study was to review the management of stomal stenosis after the Malone antegrade continence enema (MACE) procedure at our center, and to describe and assess the early outcomes of 2 novel procedures used in the management of conduit stenosis: Maceoscopy and the rendez-vous . Subjects/patients and methods We retrospectively reviewed 45 consecutive MACE cases performed by 1 surgeon at St George's hospital over a 13-year period. Results Until April 2002, 5 cases presented with difficulty catheterizing their MACE. This was attributed to stenosis without further investigation, and the MACE revised surgically. Of 13 cases presenting with suspected stenosis since May 2002, 8 channels turned out to be patent when assessed and catheterized endoscopically via Maceoscopy. Two truly stenotic MACEs were revised; patency of the other 3 was reestablished by means of a new double-endoscopic procedure we have termed the rendez-vous.
