Cancer - Bladder, Pelvis, Ureter & Others(구연) (NP-020) 방광암에서 로봇 근치적 방광절제술은 개복수술에 비해 안전한가? 분당서울대학교병원 비뇨기과학교실 김학주, 오종진 Aims: To compare perioperative outcomes and complications of robot assisted radical cystectomy and open radical cystectomy for bladder cancer. Methods: Retrospective revision of 319 patients who underwent radical cystectomy for bladder cancer between 2003 and 2018 with at least 3 months of follow-up. Group 1 with open radical cystectomy of 206 patients and group 2 with robot assisted radical cystectomy of 113 patients. Results: 319 patients, 270 men and 49 women, with a median age of 67 years and mean follow-up of 29.6 months underwent RC. A RARC was performed in 113cases, of whom 73 were ileal conduits and 49 neobladders, and open RC in 206 cases, of whom 178 were ileal conduits and 28 neobladders. The median operative time was 437 min in RARC group, and 385min in open RC group. And length of hospital stay was 15.6 days in RARC group, and 21.8days in open RC group. Patients who had postoperative complications were 71 in RARC group and 134 in open RC group, with no significant difference. The clavian dindo classification also showed no significant difference between the two groups. There were 19 people who performed intraoperative transfusions in RARC group and 153 in open RC group. Conclusions: RARC surgery is thought to reduce the possibility of bleeding during surgery compared to openRC surgery and can be inferred that it shows a rapid recovery after surgery. keywords : bladder cancer, radical cystectomy, robotic surgery
