ABSTRACT
Objective:To explore the effect of enhanced recovery after surgery (ERAS) protocols in patients undergoing laparoscopic radical cystectomy (LRC) and intracorporeal urinary diversion (ICUD).Methods:A total of 83 patients who received LRC+ ICUD in Beijing Chaoyang Hospital from March 2014 to September 2020, were divided into 2 groups based on different perioperative management, including 29 ERAS cases and 54 conventional recovery after surgery (CRAS) cases. The ERAS group included 26 males and 3 females , with an average age of (62.07 ± 9.26) years. There were 26 patients with ASA class Ⅰ-Ⅱ, 3 patients with ASA class Ⅲ, 4 patients received neoadjuvant chemotherapy, and 7 patients had a history of abdominal surgery in ERAS group. The CRAS group included 44 males and 10 females , with an average age of (61.59 ± 10.16) years. There were 50 patients with ASA class Ⅰ-Ⅱ, 4 patients with ASA class Ⅲ, 9 patients received neoadjuvant chemotherapy, and 10 patients had a history of abdominal surgery in CRAS group. There were no statistically significant differences in the baseline characteristics between the two groups. The patients in both groups underwent LRC+ ICUD procedures. The perioperative results and complications between the two groups were compared.Results:In the ERAS group, there were 20 patients who underwent Bricker ileal conduit surgery and 9 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 3, 3, 7, 7, 5 and 4 cases in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 23, 2, 3 and 1 patient with pathological stage N 0, N 1, N 2 and N 3, respectively. Pathological diagnosis included 3 cases of low-grade urothelial carcinoma, 24 cases of high-grade urothelial carcinoma, and 2 cases of other histological subtypes. In the CRAS group, there were 31 patients who underwent Bricker ileal conduit surgery and 23 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 5, 3, 12, 9, 15 and 10 patients in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 35, 6, 7 and 6 patients with pathological stage N 0, N 1, N 2, and N 3, respectively. Pathological diagnoses included 6 cases of low-grade urothelial carcinoma, 45 cases of high-grade urothelial carcinoma, and 3 cases of other histological subtypes. There were no statistically significant differences ( P>0.05) in surgical methods, pathological staging, or pathological types between the ERAS and CRAS groups. ERAS group presented less albumin loss [(25.73±8.63)% vs. (32.63±9.05)%, P=0.001], shorter hospital stay [9(7, 13)d vs. 12(9, 16)d, P=0.006], less 30-day overall complications [55.2% (16/29) vs. 83.3% (45/54), P=0.009]. In multivariable analysis, maximum albumin loss≥20% was independently associated with 30-day minor complications ( P=0.049), and maximum albumin loss ≥25% was independently associated with hospital of stay≥10 days ( P=0.038), respectively. Conclusions:For patients who received LRC+ ICUD, ERAS was associated with reduced perioperative albumin loss, shorter length of stay, less 30-day complications, accelerated recovery time, improved clinical outcome and less albumin injection.
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.
