ABSTRACT
Objective:To analyze the learning effect of laparoscopic radical cystectomy(LRC)+ modified ileal conduit(MIC).Methods:From 2014 to 2019, 42 patients underwent MIC and their clinical data was retrospectively analyzed. 34 operations were performed by surgeon 1 and 8 operations by surgeon 2. We divided the 34 patients of surgeon 1 into three groups according to their surgical sequence (group A, 1st to 12th; group B, 13th to 23th; group C, 24 th to 34 th), the 8 cases of surgeon 2 was regarded as group D. The history of abdomen surgery in the 4 groups were 0, 1, 4, 3 cases, respectively ( P<0.05). There was no significant difference of the other baseline characteristics, such as age, BMI, American Society of Anesthesiologists. Then we compared several variables between the 4 groups like operation time, time of ileal conduit construction, blood loss, complication rate, lymph node yield, surgical margin, etc. The key steps of the MIC included isolating terminal ileum when the mesentery was transilluminated, performing end-to-end reflux ureterointestinal anastomosis after the efferent loop was fixed, closing the rent of the retroperitoneum. Results:All operations were performed intracorporeally with no transition to open surgery. The operative time for group A, B, C were 330.0(320.0, 360.0)min, 300.0(250.0, 308.0)min, 270.0(216.0, 324.0)min, respectively ( P =0.010). The time of ileal conduit construction of the 3 groups were 136.5(131.3, 147.5)min, 92.0(79.0, 119.0)min, 79.0(72.0, 115.0)min, respectively ( P <0.001). In addition, the difference of the two variables above between A and B, A and C groups separately reached statistical significance ( P<0.05), while the difference between B and C groups did not ( P>0.05). Other variables, such as blood loss, complication rate, lymph node yield, surgical margin, between the 3 groups reached no statistical significance ( P>0.05). The operative time of group D was 420.0(350.0, 450.0)min, and it reached statistical significance ( P<0.05) when compared with group A. There were no significant differences in other variables, such as blood loss, complication rate, lymph node yield, surgical margin, among the 2 groups ( P>0.05). Conclusions:The learning effect of LRC+ MIC was obvious. When surgeon volume increased, the operative time decreased significantly. Variables like estimated blood loss and complication rate of the 2 surgeons did not reached significant difference, which indicated reproductivity and safety of this procedure.
