RESUMO
Objective To discuss the effect and value of wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy as urinary diversion after radical cystectomy.Methods The clinical data of 12 cases(7 males and 5 females)with bladder cancer during January 2016 and September 2017 were retrospectively analyzed.The median age was 77 years (range 75-83),and the course of the disease was 5 days to 2 years.11 cases had gross hematuria,5 cases had frequent and urgent urination,1 case had lower abdominal pain,and 1 case had no obvious clinical symptoms.9 cases had a history of transurethral prostatic resection.8 cases had a complication of hypertension,5 cases had a complication of diabetes,7 cases had a complication of cardiovascular and cerebrovascular diseases,and 6 cases had a complication of anemia.The ASA level was 3 in 9 cases and was level 4 in 3 cases.All the patiants were diagnosed of bladder urothelial carcinoma by biopsy.There were 8 cases with T3 tumor and 4 cases with T4.All the patients underwent laparoscopic radical cystectomy under general anesthesia,and wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy was used for urinary diversion.Take a segment of 3-5 cm wide pedicle omentum,which is covered from the distal end of the ureter to the end,and use a 4-0 absorbable line to fix the omentum and ureteral outer membrane,and then perform ureterocutaneostomy.The incidence of postoperative anastomotic stenosis,hydronephrosis and wound infection were observed.Results All the operations were performed successfully without obvious operative complications.The mean operating duration was125 (95-217) mins,estimated volume of blood loss 120 (50-600)ml.5 days after surgery,1 patient developed incision infection,which was cured by strengthening anti-infection drug therapy and wound dressing.No complications such as urinary fistula,intestinal fistula and peripheral hernia occurred.No death was reported during perioperative period.Single J tube was removed 1-3 months after surgery.Within a follow-up of 12 (3-23) months,1 case died of cerebral infarction 3 months after surgery,1 case occurred papilla light constriction without special treatment,no ureteral stenosis and necrosis cases and there were no cases of hydronephrosis.All the patients were satisfied with the quality of life after surgery.Conclusions Wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy is simple,safe and effective as urinary diversion after radical cystectomy.
RESUMO
Objective To investigate the difference of surgical efficacy between extended lymph node dissection and standard lymph node dissection in laparoscopic radical cystectomy.Methods We retrospectively analyzed 62 bladder cancer cases,icluding 52 males and 10 females patients in our hospital from January 2011 to October 2016,who underwent laparoscopic radical cystectomy and pelvic lymph node dissection.Their mean age was (62.5 ± 9.6) years,ranged from 42 to 83 years.27 cases were underwent extended lymph node dissection and 35 cases were underwent standard lymph node dissection respectively.The basic characters,operative time,intraoperative blood loss,intraoperative and postoperative complications,postoperative eating time,postoperative activity time,postoperative hospital stay,lymph nodes positive rate,lymph node density,and cancer-free survival were evaluated.Results All patients were underwent successful operation.There was no significant difference in operation time [(326.2 ± 77.5) min vs.(345.5 ± 66.8) min,P =0.297],blood loss [(198.2 ± 77.5) ml vs.(213.7 ± 160.0) ml,P =0.590],intraoperative complications (0/27 vs.5/35,F =0.063),postoperative complications (8/27 and 9/35,P =0.732),postoperative eating time[(4.8 ±2.2)d vs.(4.6 ± 1.9)d,P =0.817],postoperative activity time[(1.9 ± 0.8) d vs.(1.9 ± 0.9) d,P =0.838] and postoperative hospital stay[(15.6 ± 7.5) d vs.(16.0 ± 5.9)d,P =0.483].In this study,994 lymph nodes and 100 positive lymph nodes were dissected.There were significant differences in the number of lymph nodes dissected in the two groups (23.2 ±6.6 vs.10.5 ±3.6,P ＜0.01).40.74％ (11/27) of cases in ePLND were lymph node positive and the lymph node density was 11.7％ (73/626),which was higher than that of the sPLND group (28.57％ vs.7.34％,respectively).In regard to prognosis,the cancer-free survival rate (DFS) of ePLND group was 96％,91％,80％ and 71％ at 3,6,12 and 24 months follow-up respectively.The other group was 97％ 94％,84％,80％ correspondingly.And no significant difference was detected (P =0.546).Although there was no significant difference (P ＞ 0.05),DFS of ePLND group tended to be higher than that of sPLND group in lymph node positive subgroups.Conclusions Extended lymph node dissection and standard lymph node dissection have similar surgical safety and prognosis,and appropriate surgical procedures should be selected according to the patient's condition.
