Cancer - Bladder, Pelvis, Ureter & Others(구연) MP Session Ⅱ (MP-014) Geumkang Hall (Avenue 2F) 11월 28일(수) 17:00-18:00 로봇 보조 근치적 방광절제술 및 체외요로전환술 후 합병증 발생에 미치는 요인 성균관대학교 의과대학 비뇨기과학교실 이충언, 최형찬, 유지웅, 강민용, 성현환, 전황균, 한덕현, 전성수, 이현무, 서성일, 정병창 Introduction and Objective: Robot assisted radical cystectomy(RARC) is known to have less postoperative morbidity and complications than open radical cystectomy. However, various complications yet have been reported after RARC with extracorporeal urinary diversion. In this study, we tried to find factors to predict complications of RARC. Materials and Methods: From August 2008 to November 2017, we retrospectively reviewed 126 patients who underwent RARC with extracorporeal urinary diversion. Overall complications and factors that may affect complications were analyzed with logistic regression model. Complications were defined as those related to surgery during hospitalization and were classified according to the Clavien-Dindo system. Results: Complications occurred in 78 (61.9%) of 126 patients. 20 (15.9%) for grade Ⅰ, 53 (42.1%) for grade Ⅱ, 2 (1.6%) for grade Ⅲa, and 3 (2.4%) for grade Ⅲb were observed. Complications of grade Ⅳ or higher not occurred. Table 1. shows the specific complications. In the multivariate regression model, previous intravesical instillation (OR 3.374 (1.116-10.197), p = 0.0312), preoperative hemoglobin (OR = 0.751 (0.588-0.96), p = 0.022), and estimated blood loss(EBL) (OR = 3.949 (1.682-9.27), p = 0.0016) were significantly associated with the occurrence of complication. (Table 2) Conclusion: RARC had less serious complications (4.0%). Predictors postoperative complications after RARC with extracorporeal urinary diversion were hemoglobin, intravesical instillation history, and high EBL during surgery. keywords : Bladder cancer, Robot assisted radical cystectomy, Complication
