[Application of Endo-GIA stapler in laparoscopic radicalcystectomy]

Objective: To explore the application of Endo-GIA stapler in laparoscopic radical cystectomy, especially in the treatment of lateral bladder ligament, and to evaluate its clinical feasibility and practicability. Methods: A retrospective analysis of clinical data about 38 cases of laparoscopic radical cystectomy (LRC) treated in the Department of Urology, Chaoyang Hospital of Beijing and Cancer Hospital, Chinese Academy of Medical Sciences from July 2017 to June 2019 were conducted. The patients were divided into Endo-GIA stopler group(18 cases) and non-Endo-GIA stopler group (20 cases) according to whether Endo-GIA stapler were used. The basic clinical data, operation time of bladder lateral ligament, operation time of bladder lateral wall, operation time of bladder resection, amount of bleeding during operation, pathological data after operation and related indicators of recovery after operation were compared between the two groups. Results: All 38 patients underwent radical cystectomy (RC) successfully under 3-D laparoscopy without conversion to open surgery. The operation time of bladder lateral ligament in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(3.25±0.75) min vs (9.20±2.95) min, P=0.042]; the operation time of bladder lateral wall in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(8.06±1.66) min vs (14.30±3.37) min, P=0.016]. The operation time of cystectomy in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(47.06±4.70) min vs (61.60±14.91) min,P=0.003]. The amount of bleeding in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(37.77±21.30) ml vs (114.50±39.80) ml, P=0.015]. The time of drainage tube removal in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(5.83±1.54) d vs (7.30±3.00) d, P=0.002]. The length of post-hospitalization in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(7.67±1.78) d vs (9.60±3.25) d,P=0.036]. However, there was no significant difference in other basic clinical data, post-operative pathology and post-operative recovery related indicators. Conclusions: Laparoscopic radical cystectomy using Endo-GIA stapler device is safe and feasible. It is easy to operate, shorten the operation time significantly, and reduce the amount of bleeding. To a certain extent, it is conducive to the recovery of patients after operation to some extent, and worthy of clinical application.
