Simultaneous laparoscopic proctocolectomy (TaTME) and robot-assisted radical prostatectomy for synchronous rectal and prostate cancer.

OBJECTIVE: We would like to present a patient with a history of ulcerative colitis suffering from a synchronous rectal and prostate cancer treated with a laparoscopic total proctocolectomy (with TaTME) and Retzius sparing RARP simultaneously.

METHODS: Retzius sparing RARP with bilateral lymph node harvesting was performed first. Afterwards, TaTME was commenced with the placement of a Lonestar® retractor and GelPort® . Anterior dissection was troubled unexpectedly by outspoken fibrosis. For that reason, it was completed laparoscopically. We then continued with the laparoscopic total proctocolectomy. Last, a transanal circular stapled ileoanal anastomosis was created and a derivating ileostomy was installed.

RESULTS: Postoperative proctoscopy showed a patent ileoanal anastomosis. After removal of the Foley catheter on day 21, the patient was immediately continent. Prostate specimen revealed a pT2cN1M0 transmural invasive adenocarcinoma with a Gleason score of 7 (3 + 4). Pathology analysis of the rectum revealed a stage IIIc transmural invasive moderately differentiated rectal adenocarcinoma (pT3N2bM0) with free margins. He was referred for adjuvant chemotherapy.

CONCLUSIONS: In this case, the combination of TaTME and Retzius sparing RARP for synchronous rectal and prostate cancer was feasible and safe. We suggest performing the anterior TaTME dissection last, due to disturbing blood flow into the operating field after prostatectomy.
