Quality and outcomes of robotic lymphadenectomy for prostate cancer in obese and morbidly obese patients

Abstract

RESULTS: Mean BMI among the 819 patients was 30kg/m2 (1852kg/m) with 421 of BMI 30kg/m, 358 obese, and 40 morbidly bese and no difference among groups in proportion of high-risk atients. Mean total operative time was 148min, 157min, and 78min for normal, obese, and morbidly obese patients, respectively p 0.05). Estimated blood loss was 109mL, 128mL and 156mL p 0.05) with transfusion rate of only 0.4% and none in the moridly obese group. Mean hospitalization was 1.0d in all three groups. ean nodal yields were 9.6, 9.9, and 10.6 nodes for normal, obese nd morbidly obese patients (p NS). Extended PLND was perormed in 18%, 19%, and 15% with mean yields of 16.7, 15.3, and 16.5 odes, respectively (p NS). Node positivity was identified in 5.2%, .7%, and 12.5% (p NS). Complications of PLND occurred in 2%, %, and 5%, which were mostly symptomatic lymphoceles.
