Laparoscopic Radical Cystectomy with Orthotopic Ileal Neobladder for Bladder Cancer: Oncologic Results of 171 Cases With a Median 3-Year Follow-up

BACKGROUND Radical cystectomy (RC) with pelvic lymph node dissection (PLND) is the standard treatment for muscle-invasive and high-risk non-muscle-invasive bladder cancer (BCa). Large series with long-term oncologic data after laparoscopic RC (LRC) are rare. OBJECTIVE To report oncologic outcomes of LRC for 171 cases with a median 3-yr follow-up. DESIGN, SETTING, AND PARTICIPANTS From December 2002 to June 2009, 171 consecutive patients with BCa who underwent LRC with orthotopic ileal neobladder (OIN) at our institution were enrolled in this retrospective study. INTERVENTION All patients underwent LRC OIN. Adjuvant chemotherapy was administered to patients with non-organ-confined disease or positive lymph nodes. MEASUREMENTS The demographic, perioperative, complication, pathologic, and survival data were collected and analysed. RESULTS AND LIMITATIONS Most tumours were transitional cell carcinoma (TCC; 160, 93.6%). Tumours were organ confined in 113 patients (pT1-T2; 66.1%) and non-organ confined in 58 patients (pT3-T4a; 33.9%). There was involvement of the lymph nodes in 38 patients (22.2%). Surgical margins were all tumour free. The mean number of removed lymph nodes was 16 (5-46). Follow-up ranged from 3 to 83 mo, and 54 (31.6%) patients completed 5-yr follow-up. Two patients (1.2%) had local recurrence and distant metastasis, 9 patients (5.3%) had local recurrence alone, and 23 patients (13.5%) had distant metastasis. One patient (0.6%) had port-site seeding. One hundred twenty-four patients (72.5%) were alive with no evidence of recurrence; 28 patients (16.4%) died, 20 from metastasis and 8 from tumour-unrelated causes. The estimated 5-yr overall survival, cancer-specific survival, and recurrence-free survival rates were 73.7%, 81.3%, and 72.6%, respectively. The relatively low percentage of patients reaching 5-yr follow-up is a limitation of this retrospective study. CONCLUSIONS Surgical technique of LRC with OIN can achieve the established oncologic criteria of open surgery, and our oncologic outcome is encouraging. Long-term follow-up is needed for further confirmation.

Laparoscopic Radical Cystectomy with Orthotopic Ileal Neobladder: A Report of 85 Cases

PURPOSE The preliminary results of laparoscopic radical cystectomy in 85 patients are presented in this study. The functional and oncologic outcomes of this procedure in these patients are discussed. PATIENTS AND METHODS Between December 2002 and May 2006, we performed 85 laparoscopic radical cystectomies with orthotopic ileal neobladder for bladder cancer in 77 men and 8 women. A 5-port transperitoneal approach was applied. The standard bilateral pelvic lymphadenectomy was performed first, then radical cystectomy was completed laparoscopically. The construction of the ileal neobladder and the anastomosis of ureter-neobladder were performed extracorporeally. The neobladder was anastomosed to the urethral stump under laparoscopy. A nerve-sparing procedure was performed for eight patients. RESULTS The median operative time was 320 min, and the median blood loss was 280 mL. Conversion to open surgery was not necessary in any of the patients. The average time to oral intake after operation was 3.9 days. There were no perioperative mortalities. The complication rate was 14.1% (12/85), including such complications as three uretero-pouch anastomotic strictures, one vesicourethral anastomotic stricture, one pouch-vaginal fistula, one colonic pouch fistula, one ileo-pouch fistula, three ileus, one pneumonia, and one pyelonephritis. The daytime continence rate was 91.2%, and the nighttime continence rate was 82.4% at 6 months postoperatively. The neobladder capacity was about 343 mL. Surgical margins were tumor free for all patients. Of the eight patients who underwent a nerve-sparing procedure, four patients had potency for intercourse. During a follow-up period of 1 to 41 months (average 21.3 months), three patients had local recurrence, one patient had trocar site seeding, and five patients had distant metastasis, of whom four died. CONCLUSIONS Laparoscopic radical cystectomy with extracorporeal formation of a neobladder is a feasible procedure with low morbidity and acceptable neobladder function. Long-term follow-up is needed to confirm the oncologic outcomes.

A prospective randomised controlled trial of laparoscopic vs open radical cystectomy for bladder cancer: perioperative and oncologic outcomes with 5-year follow-upT Lin et al.

Background:Laparoscopic radical cystectomy (LRC) is increasingly being used for muscle-invasive bladder cancer. However, high levels of clinical evidence comparing laparoscopic vs open radical cystectomy (ORC) are lacking.Methods:A prospective randomised controlled clinical trial comparing LRC vs ORC in patients undergoing radical cystectomy for bladder cancer. Thirty-five patients were eligible for final analysis in each group.Results:The median follow-up was 26 months (range, 4–59 months) for laparoscopic vs 32 months (range, 6–60 months) for ORC. Significant differences were noted in operative time, estimated blood loss (EBL), blood transfusion rate, analgesic requirement, and time to resumption of oral intake. No significant differences were noted in the length of hospital stay, complication rate, lymph node yield (14.1±6.3 for LRC and 15.2±5.9 for ORC), positive surgical margin rate, postoperative pathology, or recurrence rate (7 for LRC and 8 for ORC). The 5-year recurrence-free survival with laparoscopic vs ORC was 78.5% vs 70.9%, respectively (P=0.773). The overall survival with laparoscopic vs ORC was 73.8% vs 67.4%, respectively (P=0.511).Conclusion:Our study demonstrated that LRC is superior to ORC in perioperative outcomes, including EBL, blood transfusion rate, and analgesic requirement. We found no major difference in oncologic outcomes. The number of patients is too small to allow for a final conclusion.

Hybrid Laparoscopic Endoscopic Single-Site Surgery for Radical Cystoprostatectomy and Orthotopic Ileal Neobladder: An Initial Experience of 12 Cases

BACKGROUND AND PURPOSE Laparoscopic endoscopic single-site surgery (LESS) has recently emerged as an attempt to enhance cosmetic benefits and reduce morbidity; however, LESS for radical cystectomy is still not well established. Here we describe the technique of hybrid LESS for radical cystoprostatectomy and orthotopic ileal neobladder (RC-OIN), and evaluate its feasibility and safety. PATIENTS AND METHODS Between November 2008 and October 2009, 12 men with bladder cancer underwent hybrid LESS for RC-OIN. A homemade multichannel port, made from two stretchable rings and a surgical glove with trocars and valves attached to its fingers, was placed into a 4- to 5-cm midline incision in the lower abdomen and was used for laparoscopic instruments. Another subumbilical port was placed for the laparoscope. Extended bilateral pelvic lymphadenectomy was performed by the lateral view; radical cystoprostatectomy was completed laparoscopically; construction of the ileal neobladder was performed extracorporeally; and the neobladder was anastomosed to the urethral stump laparoscopically, with a slipknot running suture technique. Perioperative, functional, oncologic data and complications were collected and analyzed. RESULTS All operations were performed successfully without conversion to conventional laparoscopic radical cystectomy or open surgery. There was no perioperative mortality or port-related complications. The median operative time was 383 minutes. Median blood loss was 150 mL. A median of 25 lymph nodes were removed. Surgical margins were tumor free in all cases. CONCLUSIONS Hybrid LESS for RC-OIN is technically feasible with effects similar to those of conventional laparoscopic procedures. Further instrument and technique improvement are necessary to shorten operative time and reduce intraoperative difficulties.

Surgical management of nutcracker phenomenon presenting as left varicocele in adolescents: a novel approach.

OBJECTIVE To present a new approach using a shunt operation for the management of nutcracker phenomenon presenting as left varicocele in adolescent patients. MATERIALS AND METHODS 12 adolescent patients with the nutcracker phenomenon presenting as left varicocele underwent a shunt operation consisting of anastomosis of the proximal part of the spermatic vein and inferior epigastric vein to lower the left renal vein (LRV) pressure. A simple ligation of the left spermatic vein was then used to repair the varicocele. RESULTS 12 patients underwent surgery, and symptoms of hematuria, proteinuria, scrotum discomfort, and flank pain disappeared post surgery in all patients. Patients were followed for 24-72 months (mean 48 months). The diameters of the proximal LRV and the peak velocities in the aortomesenteric portion of the LRV were significantly decreased after surgery (p < 0.001). Left testicular volume significantly increased after surgery. One patient had recurrence of the left varicocele and one adolescent had minimal hydrocele requiring no intervention. No major complications were observed during and after surgery. CONCLUSION Anastomosis of the proximal part of the spermatic vein and inferior epigastric vein is an efficacious and safe surgical approach for the management of nutcracker phenomenon presenting as left varicocele in adolescents.
