Whether laparoscopic ICIC is superior to extracorporeal ileal conduit （ECIC） and whether laparoscopic ICIC should be promoted is still controversial. The aim of the study was to compare surgical and early oncological outcomes between patients undergoing laparoscopic radical cystectomy （LRC） with ICIC and ECIC. Methods： From January 2011 to June 2016, a total of 45 patients with bladder cancer underwent LRC with ileal conduit at our department, of whom 20 patients underwent LRC with ECIC and 25 patients underwent LRC with ICIC. Data of each patient＇s characteristics, surgical outcomes, and short-term oncological outcomes were collected and analyzed. Results： LRC with ileal conduit was performed successfully on all 45 patients. There were no significant differences in patients＇ characteristics, mean total operative time, and mean estimated blood loss between the ICIC and ECIC groups. Median time of flatus and oral intake was shorter in the ICIC group compared with the ECIC group （3 vs. 5 days, P = 0.035; 4 vs. 5 days, P = 0.002）. The complications rates did not show significant difference between the two groups within the first 90 days postoperatively （P = 0.538）. Cancer staging showed 45% of patients in the ECIC group and 36% in the ICIC group had a pathologic stage of T3 or T4, and 50% of patients in the ECIC group and 44% in the ICIC group had a pathologic stage of N1 or N1＋. Kaplan-Meier analysis showed no significant difference in overall survival at 24 months （60% vs. 62%, P = 0.857） between the ECIC and ICIC groups. Conclusions： ICIC after LRC may be successful with the benefits of faster recovery time. No significant difference was found in complications and oncological outcomes between ICIC and ECIC. However, larger series with longer follow-up are needed to validate this procedure.展开更多
