Background: Although the number of cases of locally advanced colorectal cancer related to familial adenomatous polyposis (FAP) has decreased as a result of a better understanding of the disease, the condition still can offer therapeutic challenges.
Case presentation: We report a case of a rectal tumor with prostate invasion associated with FAP, treated with neoadjuvant radiotherapy and total extended proctocolectomy with cystoprostatectomy. The reconstruction was undertaken with a double-barreled ileostomy with ureteral reimplantation on the distal segment of the ileostomy. Data including surgical aspects, post-operative complications, and outcome were evaluated.
Conclusion: The double-barreled wet ileostomy is a technically straightforward and safe procedure that is easily executed and may be an alternative to simultaneous diversion in extreme situations. To the best of our knowledge, this is the first description of this procedure in the literature.
