Influence of body mass index on the outcomes of robotic-assisted laparoscopic: A comparative retrospective study

Objective. - The aim of our study was to assess the impact of body mass index (BMI) on a robot-assisted laparoscopic sacrocolpopexy (RALS) to treat genital prolapse. Methodology. - The study focused on a group of 56 women who went through a robot-assisted laparoscopic sacrocolpopexy (RALS) between 2009 and 2013. Patients were divided into 3 groups according to their BMI (kg/m(2)): BMI < 25 (n = 28), 25 <= BMI < 30 (n = 16), BMI >= 30 (n = 12). The operating parameters, results and short-term complications were analysed according to the patients' BMI. Results. - The median BMI was 22.5 kg/m(2) in group 1, 26.1 kg/m(2) in group 2, and 31.6 kg/m(2) in group 3 (P < 0.001). The operation time was respectively 250 minutes (130-380), 230 minutes (150-410) and 255 minutes (170-370), for groups 1, 2 and 3 (P = 0.689). The 3 groups spent 4 days in the hospital (P=0.562). Only one laparotomy in group 3 was reported (P = 0.214). The rate of early complications was similar in groups 1, 2 and 3 with 3/28, 0/16 and 0/12 respectively. Anatomical short-term results were identical in the 3 groups with a satisfactory anatomical correction in 100% of all cases (ICS POP-Q < 2). Conclusion. - In this small group, we observed that the BMI had no impact neither on the operation time nor on the rate of complication. (C) 2013 Elsevier Masson SAS. All rights reserved.
