Objective To evaluate the feasibility and efficacy of laparoscopic repair of vesicovaginal fistula (VVF) with omentum shift.Methods Sixteen VVF patients were reviewed retrospectively from July 2007 to July 2011,aged from 34 to 72 years with a mean age of 48 years.The history of leakage of urine ranged from 1 month to 30 years,of which 15 cases due to uterine operation complication and 1 case due to IUD perforation.All cases were single fistula,with the fistula diameter ＜ 1 cm in 13 cases and ＞ 1 cm in 3 cases.Fourteen cases of fistulas were in the vaginal wall,and 2 cases were in the cervix.Surgical techniques were transabdominal laparoscopic local displacement of the great omentum and conventional layered suture repair of vesicovaginal fistula.Results All surgeries were successful.The operation time was 120 -175 min,with an average of 150 min.The blood loss was 50 -300 ml,with an average of 120 ml.The postoperative hospital stay was 6 to 10 d,with an average of 8.5 d.The catheter indwelling time was 14 to 21 d,with an average of 17 d.During the period of follow-up for 3 to 45 months with an average of 23months,14 cases cured,1 case improved and 1 case failed.No major complications such as intestinal injury occurred.Conclusions Laparoscopic repair of VVF with great omentum shift has the characteristics of less damage,less pain and positive effect.The key points of the surgery are local filling of great omentum and delicate layered suture.

Objective To summarize the causes and treatment strategies for laparoscopic vascular injuries.Methods We had retrospectively reviewed 1858 cases of laparoscopic surgeries from March 2006 to February 2011.There were 10 cases (6 males and 4 females) had intraoperative vascular injuries.The mean age of these 10 patients was 49 years (ranged from 21 to 78 years).2 cases were aortic injuries,2 cases were vena cava injuries,4 cases were renal vein injuries,1 case was iliac vein injury and 1 case was iliac artery injury.The causes of vascular injuries included 2 cases caused by lack of anatomical understanding; 1 cases occurred during establishment of the first puncture site ; 2 cases caused by forced operation during the procedure; 2 cases caused due to ectopic anatomy; 3 cases caused due to adhesions and difficulties in dissection.Treatment strategies were maintaining pneumoperitoneum pressure and rapidly increasing the pressure to 2.6Kpa if a large amount of bleeding in a short time.With the help of suction,the bleeding sites could be identified.If necessary,an additional trocar was added to help exposure.The bleeding was closed with 4-0 vessel sutures.For arterial bleeding,the upper and lower ends of blood vessel ruptures were clipped with bulldog clamp,then follow the same procedures of variceal bleeding sutures if the bleeding were controlled.Results In 7 of the 10 cases,the bleedings were successfully controlled by laparoscopic technique,while the other 3 were converted to open surgery for bleeding control.The average laparoscopic hemostasis time in the 7 cases was 14 min (range from 8 to 25 min),the average blood loss was 530 ml (range from 150 to 1600 ml).Rupture size were 0.2-1.0 cm.One aortic injury case had complication of big post operative local hematoma which was spontaneously absorbed 3 months after surgery.And the other 9 patients did not have air embolism,hemorrhage and other complications.Conclusions Laparoscopic vascular injuries can be caused by a variety of causes.The strategies of controlling the bleeding are calmness and the fine suturing to control bleeding.A skillful assistant also plays an important role in dealing with this complication.

ObjectiveTo investigate the feasibility,technique and clinical effect of applying laparoscopic plastic surgery in the treatment of horseshoe kidney.Methods Eleven patients with horseshoe kidney were admitted from Mar.2006 to Mar.2011.There were 5 males and 6 females with mean age of 27years (14 to 46 years).Clinical manifestations included lower-back pain in 8 cases,lower-back pain and hematuria in 2 cases,lower-back pain and fever in 1 case.There were 6 cases accompanied with kidney calculi.All the cases with calculus were in left kidney and there was 1 case with multiple calculi.There were 11 cases accompanied with left hydronephrosis.Of which,there were moderate hydronephrosis in 6 cases,severe hydronephrosis in 5 cases.There were 3 cases accompanied with mild right hydronephrosis.There were 2 patients with renal insufficiency,1 patient with urinary tract infection.The surgery procedures included laparoscopic isthmectomy and plastic surgery in 3 cases,isthmectomy and plastic surgery and pelviolithotomy in 6 cases,isthmectomy and vascular compression release in 2 cases.ResultsAll patients had successful surgeries with the mean operative time of 145 min (95 - 190 min).The average blood loss was 250 ml ( 100 -400 ml).Average postoperative hospital stay was 10 d (7 - 15 d).One patient suffered from urinary leakage after surgery and recovered after anti-inflammatory therapy and local drainage.One patient suffered from secondary hemorrhage controlled with DSA.All the patients were followed up with a mean of 17 months (6 -28 months).In 6 cases with moderate hydronephrosis,5 patients recovered to mild hydronephrosis and 1 case improved from preoperative renal hydronephrosis 3.5 cm to postoperative 3.0 cm.In 5 cases with severe hydronephrosis,3 patients improved to moderate hydronephrosis,2 patients to mild hydronephrosis.One patient with kidney stone had 0.4 cm residual stone.Three patients complained of occasional mild backache.One patient suffered from hematuria and urinary tract infection,recovered after antiinflammatory therapy for 2 weeks.The remaining 6 patients were in good conditions during the follow-up.ConclusionTransperitoneal laparoscopic plastic surgery is able to deal with horseshoe kidney isthmus malformation and comorbidities,and is another alternative for the treatment of horseshoe kidney.
