Abstract

We aimed to examine whether body mass index (BMI) had an impact on clinical outcomes of laparoscopic radical cystectomy with intracorporeal urinary diversion. Furthermore, we analyzed the optimization of enhanced recovery protocols (ERPs) on the impact of BMI on clinical outcomes. By searching our database, data of 83 consecutive patients were retrospectively collected, including 37 patients with a BMI <24 kg/m2 (group A) and 46 patients with a BMI ≥24 kg/m2 (group B). The baseline and peri-operative variables of the two groups were compared. Subgroup analysis was conducted for ERPs (11 patients in group A1, 18 patients in group B1) and conventional recovery protocols (CRPs; 26 patients in group A2, 28 patients in group B2). The primary outcomes were 30-day overall complication rate and ΔALBmin (reduction proportion of minimum albumin). The secondary outcomes were operative time and length of stay. The baseline variables were similar between the two groups (P>0.05). The 30-day overall complication rate, operative time, and length of stay were similar between the two groups (P>0.05). But post-operative nausea and vomiting (PONV) was higher in group A than in group B (32.4% vs. 8.7%, P=0.014). Group A was associated with lower serum albumin level pre-operatively and on post-operative days 1-3. ΔALBmin was higher in group A than in group B (33.08%±9.88% vs. 27.92%±8.52%, P<0.05). In the subgroup analysis, the CRPs group presented similar results, with group A2 showing higher PONV rate, lower albumin level pre- and post-operatively, and higher level of reduction proportion (P<0.05). For the ERPs group, the PONV rate, pre-operative albumin level, and reduction proportion were similar between group A1 and B1 (P>0.05). Multivariable analysis showed that PONV and CRPs were independently associated with ΔALBmin ≥34% (P<0.05). BMI had no impact on the 30-day overall complication rate, operative time, and length of stay of patients who underwent laparoscopic radical cystectomy with intracorporeal urinary diversion. BMI <24 kg/m2 was associated with higher PONV rate and more albumin loss, both of which could be optimized by ERPs. 2021 Translational Andrology and Urology. All rights reserved.
