Port sites of daVinci^® robot-assisted low anterior resection of the rectum and laparoscopic radical prostatectomy. Asterisk Right lateral 8-mm port below the umbilicus which was used to 12-mm trocar for introduction of endo-GIA during robotic assisted low anterior resection. For robot-assisted laparoscopic radical prostatectomy, 8-mm working arm was reinserted with secure suture to prevent CO2 leakage. Hash The extraction site of both specimens which was closed once after robotic assisted LAR and 12-mm trocar was replaced for robot-assisted laparoscopic radical prostatectomy
