Evaluation of surgical complications incidence after radical cystectomy

Objective: to study the frequency of surgical complications and postoperative mortality after radical cystectomy (RCE). Material and methods. In study included 107 patients who underwent RCE by one surgeon. Starting in 2015, the protocol for accelerated recovery of patients after surgery, ERAS was applied in all patients undergoing RCE. The frequency of complications and mortality was studied depending on the age of the patients and the ERAS protocol. There were 84 male (78.5 %) and 23 female (21.5 %) in this study. All patients were divided into 2 groups: 1st group - 89 (83.0 %) people younger 75 years and 2nd group - 18 (17.0 %) people from 75 years and older. Depending on the application of the ERAS protocol, patients in each group were divided into 2 subgroups. Group 1st consists of subgroups: 1(A) - 40 (45.0 %) patients with ERAS protocol, 1(B) - 49 (55.0 %) patients without ERAS protocol. Group 2nd also consists of subgroups: 2(A) - 8 (44.4 %) patients with ERAS protocol, 2(B) - 10 (55.6 %) patients without ERAS protocol. The average age of the patients was 65.5 (32-85) years. Results. Totally, over the 90-day period after the operation, 55 cases (51.4 %) of complications were recorded: Clavien-Dindo I-II in 1st group - 27 (30.3 %), in 2nd group - 8 (44.4 %). Complications of Clavien-Dindo III-IV in the 1st group - 15 (16.8 %), in the 2nd group - 5 (27.7 %). The overall 90-day mortality was 10 cases (9.3 %): in 1st group - 8 (9.0 %) patients, in 2nd group - 2 (11.1 %) patients. According to the comparative study of the use of the ERAS protocol in subgroup 1(A), the incidence of complications of the Clavien-Dindo I-II category was noted in 11 (27.5 %) patients, and in subgroup 1(B) in 16 (32.6 %) patients. Complications of Clavien-Dindo III-IV in subgroup 1(A) were observed in 5 (12.5 %) patients and in subgroup 1(B) - in 10 (20.4 %) patients; in subgroup 2(A), the incidence of Clavien-Dindo I-II complications was noted in 3 (37.5 %) patients, and in subgroup 2(B) - in 5 (50.0 %) patients. Complications of Clavien- Dindo III-IV in subgroup 2(A) were observed in 2 (25.0 %) patients and in subgroup 2(B) - in 3 (30.0 %) patients. Thus, the ERAS proto- col decreased the number of complications in the subgroup 1(A) compared to the subgroup 1(B) (z = 1.44; p = 0.08) and between the subgroup 2(A) and 2(B) (z = 1.39; p = 0.09). Also there was an increase in the number of complications in older subgroups: in subgroup 2(B) compared with subgroup 1(B) (z =1.86; p = 0.068). The 90-day mortality in subgroup 1(A) was in 3 (7.5 %) cases, 1(B) - 5 (10.2 %) cases. The 90-day mortality in subgroups 2(A) was in 1(12.5 %) case, in subgroup 2(B) was 1(10.0 %) cases. Repeated hospitalization for the first 90 days was 14 (13.0 %) cases, with differences in the frequency of rehospitalization depending on age and application of the ERAS protocol. Conclusion. RCE is an acceptable method of treatment in patients of the older age group and should be performed in hospitals with experience of regular treatment of this nosology. Application of the ERAS protocol (accelerated recovery after surgery) in patients undergoing RCE allows, regardless of age, to reduce the incidence of early postoperative surgical complications and mortality.
