Operative Outcomes
Operative characteristics of the patients are listed in Table 2. There were no statistically significant differences in urinary diversion type, drain and nasogastric tube withdrawal time, intestinal motility, mobilization and length of stay between the groups. Open RC was performed in 419 (84.8 %) patients and 75 (15.2 %) patients underwent laparoscopic RC (p=0.008). The mean operative time was 317.1±92.1, 339.2±112.1, and 360.6±120.2, in Group 1, 2 and 3, respectively. Among the groups, more convenient inferences were obtained in Group 3, including longer operation time and oral feeding start (p=0.019, p<0.001). Patients’ readmission to hospital within 30 and 90 days of surgery were 13.2% and 16.2%, respectively, and there was no difference between the groups (p=0.710, and p=0.275 respectively). The mean number of removed lymph nodes was 19.5±14.9, 20.1±12.8 and 19.3±10.4 in Group 1, 2 and 3, respectively. There was no difference between the 3 groups in terms of lymph node positivity (p=0.210). Groups were also similar in terms of surgical margin positivity (p=078).
Perioperative complication was seen in 17(8.4%), 4(1.9%) and 5(6.5%) patients in Group 1, 2 and 3, respectively and Group 2 had significantly fewer complication rate\souts compared with Group 1 and 3 (p=0.01). Statistically significant major complication rate was observed in Group 3 compared to Group 1 and 2 (p=0.025 ). There was no significant difference between groups in terms of transfusion (perioperative, postoperative) and readmission rates (30-day, 90-day) (Table 3 ). All of the pathological characteristics of the patients were found to be similar among the groups (Table 4 ).
