Robotic-assisted laparoscopic surgery for synchronous primary rectal and prostate cancer: Initial case series.

Few studies have reported the simultaneous resection of synchronous rectal and prostate cancers. Here, we report five patients undergoing simultaneous robotic-assisted laparoscopic surgery (RALS) for synchronous rectal and prostate cancer. Rectal cancer operative procedures were high anterior (n =1), intersphincteric (n =2), or abdominoperineal (n =2) resection, followed by radical prostatectomy with vesico-urethral anastomosis. There were no conversions to open surgery, with R0 resection achieved for all rectal cancer cases. The median operative time was 629 (range, 431-764) minutes, and the median estimated blood loss was 100 (range, 20-345) mL. There was one case of colorectal anastomotic leakage requiring covering ileostomy, and two cases of vesico-urethral anastomotic leakage requiring Foley catheter reinsertion. Ileostomies were finally closed in all patients. Pad-free or safety-pad usage for post-surgical urinary incontinence at 6 and 12 months was 3/5 and 5/5, respectively. Simultaneous RALS for synchronous rectal and prostate cancer may offer a safe and feasible approach in selected patients.
