Modified seromuscular tube: serosa lined bowel wall imbrication as a continent outlet for continent cutaneous urinary diversion
Abstract
PURPOSE: We created a simplified modification of the seromuscular tube technique for continent cutaneous urinary diversion.
MATERIALS AND METHODS: We applied a simplified modification of our seromuscular tube technique in 1 woman and 2 men with a mean age of 53 years in whom outlet failure developed after continent cutaneous urinary diversion, and in whom adiposity and postoperative adhesions rendered revision difficult. We constructed a continent outlet conduit by imbricating the whole bowel wall and suturing it into a tube.
RESULTS: At a followup of 4 to 13 months (mean 7) all 3 patients are completely continent without leakage. Catheterization is performed at 3 to 5-hour intervals (mean 4) with 14 to 16Fr catheters.
CONCLUSIONS: The wall imbrication technique involves the flap valve principle, as does the seromuscular tube, and it is easy to perform. To date followup is too short for judging the long-term reliability of this continence mechanism. If the outcome stands the test of time in this series, which represents the worst case scenario, application of this technique may be extended to continent cutaneous urinary diversion.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
