Robot-assisted laparoscopic vs open radical cystectomy: comparison of complications and perioperative oncological outcomes in 200 patients
Menée sur 200 patients atteints d'un cancer de la vessie traité entre 2006 et 2010, cette étude rétrospective compare les données péri-opératoires (stade de la maladie, nombre de ganglions réséqués, taux de marges de résection positives) et le taux de complications d'une cystectomie radicale laparoscopique assistée par robot et d'une cystectomie radicale par voie ouverte
Objective : To compare perioperative morbidity and oncological outcomes of robot-assisted laparoscopic radical cystectomy (RARC) to open RC (ORC) at a single institution. Patients and Methods : A retrospective analysis was performed on a consecutive series of patients undergoing RC (100 RARC and 100 ORC) at Wake Forest University with curative intent from 2006 until 2010. Complication data using the Clavien system were collected for 90 days postoperatively. Complications and other perioperative outcomes were compared between patient groups. Results : Patients in both groups had comparable preoperative characteristics. The overall and major complication (Clavien ≥3) rates were lower for RARC patients at 35 vs 57% (P = 0.001) and 10 vs 22% (P = 0.019), respectively. There were no significant differences between groups for pathological outcomes, including stage, number of nodes harvested or positive margin rates. Conclusion : Our data suggest that patients undergoing RARC have perioperative oncological outcomes comparable with ORC, with fewer overall or major complications. Definitive claims about comparative outcomes with RARC require results from larger, randomised controlled trials.
