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.
