An audit of early complications of radical cystectomy using Clavien-Dindo classification

Abstract

Introduction: Despite the major improvements in surgical technique and perioperative care, radical cystectomy (RC) remains a major operative procedure with a significant morbidity and mortality. The present study analyzes the early complications of RC and urinary diversion using a standardized reporting system. Materials and Methods: Modified Clavien-Dindo classification was used to retrospectively assess the peri-operative course of 212 patients who had RC with urinary diversion between October 2003 and October 2014 at a single institution. The indications for surgery were muscle invasive urothelial carcinoma, high-grade nonmuscle invasive bladder cancer (BC), and Bacillus Calmette-Guerin-resistant nonmuscle invasive BCs. Data on age, sex, comorbidities, smoking history, American Society of Anaesthesiologists score, and peri-operative complications (up to 90 days) were captured. Statistical analysis was performed using SPSS 20.0 software (Chicago, USA). Results: The mean age was 56.15 ΁ 10.82. Orthotopic neobladder was created in 113 patients, ileal conduit in 88 patients, and cutaneous ureterostomy in 11 patients. A total of 292 complications were recorded in 136/212 patients. 242 complications (81.16%) occurred in the first 30 days, with the remaining 50 complications (18.83%) occurring thereafter. The rates for overall complication were 64.1%. The most common complications were hematologic (21.6%). Most of the complications were of Grade I and II (22.9% and 48.9%, respectively). Grade IIIa, IIIb, IVa, IVb, and V complications were observed in 10.2%, 8.9%, 3.4%, 2.7%, and 2.7% of the patients, respectively. Conclusions: RC and urinary diversion are associated with significant morbidity. This audit would help in setting a benchmark for further improvement in the outcome.
