Does previous abdominal surgery adversely affect perioperative and oncologic outcomes of laparoscopic radical cystectomy?

BACKGROUND Laparoscopic radical cystectomy (LRC) has been shown to have less estimated blood loss (EBL), transfusion rate, narcotic analgesic requirement, earlier return of bowel function, and shorter hospital stay. The aim of this study was to investigate the feasibility, peri-operative and oncologic outcomes of laparoscopic radical cystectomy (LRC) in patients with previous abdominal surgery (PAS). METHODS We retrospectively reviewed 243 patients undergoing open radical cystectomy (ORC) or LRC with bilateral pelvic lymph node dissection and urinary diversion or cutaneous ureterostomy at a single center from January 2010 to December 2015. Demographic parameters, intra-operative variables, peri-operative records, pathologic outcomes, and complication rate were reviewed to assess the impact of PAS on peri-operative and oncologic outcomes. RESULTS Patients in both ORC and LRC subgroups were homogeneous in terms of demography characteristics including age, gender, BMI, ASA score, and comorbidity. Estimated blood loss (EBL) was higher in patients with PAS undergoing ORC compared to those with no PAS (P = 0.008). However, there was no significant difference of EBL among patients undergoing LRC with or without PAS (P = 0.896). There was no statistical difference in peri-operative parameters and pathological outcomes. Patients with PAS undergoing ORC and ileal conduit had a higher vascular injury rate (P = 0.017). Comparing patients with PAS performed by LRC and ORC, the number of patients with the vascular injury was higher in ORC groups regardless of the type of diversion (ileal conduit, P = 0.001, cutaneous ureterostomy, P = 0.025). There is no significant difference in other complications. CONCLUSION The presence of adhesions from PAS is not a contraindication to LRC. Patients with PAS may benefit from LRC with lower estimated blood loss, fewer transfusion rates, and vascular injuries. Furthermore, the overall oncologic outcomes and complication rate are similar between LRC and ORC patients with PAS.
