In brief
Retrospective study of 106 patients comparing bowel segment choices for simultaneous urinary and fecal continent catheterizable channels. Split-appendix technique showed shorter operative times and hospital stays without compromising long-term revision rates compared to Monti channels or appendix-only approaches.

Abstract
Introduction
When creating a continent catheterizable channel (CCC) the choice of bowel segment used as the conduit should be tempered with the morbidity associated with it. The split-appendix technique allows the creation of both a urinary and fecal CCC without the need for a bowel anastomosis. However, there is concern that by splitting the appendix there is compromise to its blood supply and may affect outcomes. We aim to compare what affect the bowel segment used for urinary and fecal CCCs has on perioperative and long-term outcomes in patients undergoing simultaneous urinary and fecal reconstruction.
Methods
A retrospective review was performed analyzing all patients that underwent simultaneous continent catheterizable urinary and fecal CCC between the years 2010–2016. Patient demographics, channel characteristics, perioperative complications and clinical success rate were analyzed.
Results
A total of 106 patients were identified that had simultaneous fecal and urinary CCC created at time of reconstruction. For urinary CCC, there were 64 patients (60.4%) that underwent a split-appendix technique, 27 patients (25.4%) underwent a Monti, and 15 patients (14.2%) had the appendix used only for the urinary channel. Those patients undergoing a split-appendix technique had median operative time of 447 min compared to 619 min when a Monti channel was created. The median length of hospital stay was 9 days for the split-appendix technique compared to 12 and 13 day median hospital stay when the appendix was used only for the urinary channel or a Monti was created, respectively. There was no difference seen in revision free survival of the channel following surgery of any of the channels with median follow-up of 44.5 months. However, there were more subfascial revisions of urinary CCC in those that underwent a Monti (5 patients, 18.5%) compared to other bowel segments (0 patients).
Conclusions
Utilizing a split-appendix approach for creation of urinary and fecal CCCs does not affect 30-day complications or long-term revision rates compared to other established techniques. This technique minimizes the potential surgical morbidity of a bowel anastomosis and provide shorter operative times, when feasible, at time of simultaneous creation of fecal and urinary CCC.
