ABSTRACT
Objective To investigate the clinic efficacy of two section and three leaves approach on laparoscopic radical cystectomy (LRC) or robot assisted radical cystectomy (RARC).Methods A retrospective statistical analysis collected a total of 103 cases with bladder cancer undergoing LRC or RARC,from Jan 2013 to Dec 2015 in our center.Those patients were divided into two groups,including two section and three leaves approach group (46 cases) and conventional group (57 cases).The two section,which means that to cut lateral prostate gland and lateral vesical gland respectively,the three leaves include lateral lobe of lateral vesical gland (superior vesical arteries and veins),medial lobe of lateral vesical gland and lateral prostate gland.In two groups,whose age ranged from 35 to 84 years,the median age were (63.3 ± 9.8) years and (63.7 ± 9.1) years,respectively.The median BMI values were (23.2 ± 2.9) kg/m2 and (23.0 ± 2.2) kg/m2,respectively.The occurrence of history of abdominal surgery were 4 (8.7％) cases and 9(15.8％) cases,respectively.In two section and three leaves approach,the ASA scores of 1,2,3 were found in 5,35,6 cases,respectively.In conventional group,the ASA scores of 1,2,3 were found in 12,38,7 cases,respectively.The difference between two groups in age distribution,BMI value,ASA score,history of abdominal surgery,urinary diversion,surgical methods,pathological staging and grading had no statistical significance (P ＞ 0.05).Then,the operation time,the blood loss and the time to remove drainage tube,et al of the above two groups were compared.Patients with BMI≥24 kg/m2 in the two groups were 24 cases and 20 cases,respectively,following the strategy based on BMI ≥24 kg/m2 and BMI ＜ 24 kg/m2 to compare the difference of subgroups in the operation time and the bleeding amount,for the purpose of corroborating the applied effectiveness of two section and three leaves approach compared with the conventional measure on LRC or RARC for patients with BMI ≥ 24 kg/m2.Results All endoscopic operations were completed successfully.No conversion was recorded.In two groups,the median operation time were (255.1 ± 99.3) min and (284.2 ± 171.3) min,respectively,the difference was statistically significant (P =0.011).The blood loss was (233.1 ± 196.9)ml and (272.0 ±268.8) ml,respectively(P =0.009).The time to remove drainage tube were (10.6 ± 5.0) d and (9.9 ± 4.4) d,respectively (P =0.880).In addition,the difference in the intraoperative blood transfusion rate(10.9％ vs.21.1％),occurrence of lymph fistula (13.0％ vs.17.5％),gastric extubation time [(4.3 ± 1.9) d vs.(4.0 ± 1.9) d],time for flatus recovery [(3.9 ±1.2) d vs.(3.7 ± 1.7) d],the incidence of perioperative complications (26.1％ vs.36.8％) and postoperative hospital stay [(13.3 ± 5.5) d vs.(13.5 ± 4.8) d] were no statistical significance (P ＞0.05).The results of comparisons for patients with BMI ≥ 24 kg/m2 between subgroups included the operation time were (264.3 ± 68.1) min and (298.5 ± 80.2) min,respectively.The blood loss were (247.8 ± 199.4) ml and (295.3 ± 204.5) ml,respectively,both of them were statistical significance (P ＜0.05).The two section and three leaves approach was significantly better than those patients operated by conventional method.Conclusions Compared with conventional method undergoing LRC or RARC,two section and three leaves approach could shorten operative time and reduce the blood loss markedly,especially for patients with BMI≥24 kg/m2.
ABSTRACT
Objective To summarize the surgical experience and primary follow-up results for robotic assisted radical cystectomy ( RARC ) , as well as to evaluate the safety and feasibility of this procedure.Methods From Jan 2013 to Oct 2015, we retrospectively analysis the perioperative data and primary follow-up data from 35 patients who underwent radical cystectomy with Da VinCi robotic laparoscopic in urological institution of Changhai Hospital.The median age was 65 (ranging from 46 to 78) years.The amount of male cases were 34, the female case were 1.There were three kinds of urinary diversion, ureterocutaneostomy, Bricker operation and orthotopic neobladder, were 2, 26 and 7 respectively.We collected the parameters including operating time, estimated blood loss, blood transfusion volume, time to flatus,length of hospital stay,perioperative complication,time of recurrence,time of death and the reason of death.Results All of the related operations had been accomplished successfully, none of which had been converted to the open procedure.The estimated operating time of ureterostomy was (315.0 ±106.1) min, Ideal conduit was ( 443.2 ±93.2 ) min, Orthotopic bladder was ( 488.3 ±80.6 ) min.The estimated intraoperative blood loss was 260.0 ±108.6(100 to 500 )ml.5 cases of all patients were transfused 400ml red cell suspension, the transfusion rate was 14.2%.The mean time to flatus was 3.1 ±1.6(1 to 7) d.The estimated time to remove the gastric tube and the drainage tube was 4.2 ±2.2d(2-10d),10.8 ±5.1d(4-25d),respectively.The length of hospital stay after surgery was 12.4 ±5.17(6 to 25) d.Overall,17,8, 10,31 and 4 of these patients had
