Laparoscopic radical cystectomy for 43 patients with invasive bladder carcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>To report initial experience with laparoscopic radical cystectomy in 43 patients with invasive bladder carcinoma.</p><p><b>METHODS</b>From December 2003 to October 2006, 29 men and 14 women underwent laparoscopic radical cystectomy with extracorporeal-assisted urinary diversion for transitional cell carcinoma of the bladder (n=40), adenocarcinoma (n=2) and squamous cell arcinoma (n=1). We report the specific technical details and present initial results of our series.</p><p><b>RESULTS</b>The mean operative time of laparoscopic radical cystectomy with pelvic lymph node dissection was 195.4 min, the mean blood loss 273.7 ml, and the transfusion rate 6.9%. Two procedures converted to open techniques. Lymphadenectomy detected lymph node metastasis in three patients.</p><p><b>CONCLUSIONS</b>We demonstrate that the combination of laparoscopic radical cystectomy and extracorporeal urinary diversion is possible and remains a safe, feasible, and repeatable surgical technique. The laparoscopic surgery with extracorporeal urinary reconstruction is emerging as a viable alternative to open radical cystectomy while characterized by less trauma, short recovery time and low complications. Intermediate oncologic outcomes are encouraging and comparable to those of open series. To determine the oncologic outcome long-time follow-up will be necessary.</p>

Combination of laparoscopic and open procedure in dismembered pyeloplasty: report of 51 cases / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Laparoscopic dismembered pyeloplasty with less trauma than open surgery is commonly performed for ureteropelvic junction obstruction despite a longer operating time and a long learning curve. We describe in this paper a new technique, which combines laparoscopic and open procedure in dismembered pyeloplasty, that we have developed in 51 patients and achieved excellent results.</p><p><b>METHODS</b>The surgical procedure can be divided into two steps: laparoscopic dissection of the renal pelvis and proximal ureter transperitoneally; then accomplishing the pyeloplasty through the extended port incision above the ureteropelvic junction as in open surgery.</p><p><b>RESULTS</b>All 51 operations were successful without conversion to open surgery. No intraoperative complications were observed. The operating time was 40 minutes to 90 minutes with an average of 57.5 minutes. The estimated blood loss was 15 ml to 30 ml with an average of 21.2 ml. Aberrant artery vessel and primary stricture as the cause of ureteropelvic junction obstruction was noted in 2 and 49 patients, respectively. Thirty-nine patients had fever to differing extents in the 4 days postoperation and no severe infection was observed. Four patients had urinary leakage with their drains being retained for 6 days, 6 days, 5 days or 8 days after the operation. The mean followup was 10.8 months (range 3 months to 36 months). The followup showed good results with symptom resolution in all the patients. Renal ultrasonography demonstrated that the average separation of the collecting systems decreased from preoperative 2.7 cm (range 2.0 cm to 4.7 cm) to postoperative 1.5 cm (range 1.0 cm to 2.3 cm). Excretory urography at 3 months postoperatively showed improved drainage. Of the 51 patients, 35 underwent two or more excretory urograms, demonstrating stable renal function, improved drainage and no evidence of recurrent obstruction. At the last followup visit, each patient was doing well.</p><p><b>CONCLUSIONS</b>Combination of laparoscopic and open procedure in dismembered pyeloplasty offers a simpler, timesaving method in a minimally invasive fashion with low morbidity for patients with ureteropelvic junction obstruction. Ensuring quality of repair, the method provides a minimally invasive alternative with good results. It is worth future clinical application.</p>

Laparoscopic technique combined with open surgical technique in pyeloplasty(report of 45 cases) / 中华泌尿外科杂志

Objective To assess the laparoscopic technique combined with open surgical technique in pyeloplasty.Methods Overall,45 patients with ureteropelvic junction obstruction underwent laparo- scopic dissection of the renal pelvis and upper ureter transperitoneally,and pyeloplasty was performed through a expanded trocar-incision(extension of 1-2 cm)as open surgery was performed.Results The opera- tion was successful in all 45 patients.The mean operative time was 58 min(range,40-85 min),and the mean blood loss was 22 ml(range,15-30 ml).No complication was observed during and after operation. Follow-up for 3-36 months was available in 34 patients.Intravenous urography(IVU)showed no obstruc- tion of the anastomotic stoma,and B-ultrasound indicated relief of hydronephrosis.Conclusions Laparo- scopic approach combined with open surgery in pyeloplasty is an effective way to treat ureteropelvic junction obstruction.This technique can simplify the operative manipulation and shorten the operative time without more trauma to the patients.It is worth general application in clinical practice.
