The morbidity of laparoscopic radical cystectomy: analysis of postoperative complications in a multicenter cohort by the European Association of Urology (EAU)-Section of Uro-Technology

PURPOSE

To analyze postoperative complications after laparoscopic radical cystectomy (LRC) and evaluate its risk factors in a large prospective cohort built by the ESUT across European centers involved in minimally invasive urology in the last decade.

METHODS

Patients were prospectively enrolled, and data were retrospectively analyzed. Only oncologic cases were included. There were no formal contraindications for LRC: Also patients with locally advanced tumors (pT4a), serious comorbidities, and previous major abdominal surgery were enrolled. All procedures were performed via a standard laparoscopic approach, with no robotic assistance. Early and late postoperative complications were graded according to the modified Clavien-Dindo classification. Multivariate logistic regression was performed to explore possible risk factors for developing complications.

RESULTS

A total of 548 patients were available for final analysis, of which 258 (47%) experienced early complications during the first 90 days after LRC. Infectious, gastrointestinal, and genitourinary were, respectively, the most frequent systems involved. Postoperative ileus occurred in 51/548 (9.3%) patients. A total of 65/548 (12%) patients underwent surgical re-operation, and 10/548 (2%) patients died in the early postoperative period. Increased BMI (p = 0.024), blood loss (p = 0.021), and neoadjuvant treatment (p = 0.016) were significantly associated with a greater overall risk of experiencing complications on multivariate logistic regression. Long-term complications were documented in 64/548 (12%), and involved mainly stenosis of the uretero-ileal anastomosis or incisional hernias.

CONCLUSIONS

In this multicenter, prospective, large database, LRC appears to be a safe but morbid procedure. Standardized complication reporting should be encouraged to evaluate objectively a surgical procedure and permit comparison across studies.

A dual-centre, cohort comparison of open, laparoscopic and robotic-assisted radical cystectomy

INTRODUCTION

The role of minimally invasive radical cystectomy as opposed to open surgery for bladder cancer is not yet established. We present comparative outcomes of open, laparoscopic and robotic-assisted radical cystectomy

MATERIAL AND METHODS

Prospective cohort comparison of 158 patients from 2003-2008 undergoing open radical cystectomy (ORC) (n = 52), laparoscopic radical cystectomy (LRC) (n =58) or robotic-assisted radical cystectomy (RARC) (n = 48) performed by a team of three surgeons at two hospitals. Peri-operative data, complication rates, length of hospital stay, oncological outcome (including lymph node status) and survival were recorded. Statistical analyses were adjusted to account for potential confounding factors such as ASA grade, gender, age, diversion type and final histology.

RESULTS

RARC took longer than LRC and ORC. Patients were about 30 times more likely to have a transfusion if they had ORC than if they had RARC (p < 0.0001) and about eight times more likely to have a transfusion if they had LRC compared with RARC (p < 0.006). Patients were four times more likely to have a transfusion if they had ORC as compared with LRC (p < 0.007). Patients were four times more likely to have complications if they had ORC than RARC (p = 0.006) and about three times more likely to have complications with LRC than with RARC (p = 0.02). Hospital stay was mean 19 days after ORC, 16 days after LRC and 10 days after RARC.

CONCLUSIONS

Despite study limitations, RARC had the lowest transfusion and complication rates and the shortest length of stay, although taking the longest to perform.

Analysis of early complications of robotic-assisted radical cystectomy using a standardized reporting system

OBJECTIVE

To analyze the early complications of robotic-assisted laparoscopic radical cystectomy (RARC) with extracorporeal ileal conduit or orthotopic (Studer) bladder reconstruction using the Clavien Classification, the management of these complications, and possible preventive measures.

MATERIALS AND METHODS

Detailed data on all patients undergoing RARC were recorded prospectively on an encrypted database, including intraoperative or postoperative complications within 90 days of surgery. Outcome data during follow-up of up to 4 years was also collected prospectively.

RESULTS

A total of 50 patients (M:F 44:6) underwent RARC and extracorporeal ileal conduit urinary diversion (n = 45) or orthotopic bladder reconstruction (n = 5) between 2004 and 2008. The overall perioperative complication rate was 17 of 50 (34%), including 3 (6%) Clavien I, 9 (18%) Clavien II, and 5 (10%) Clavien III. Final histology showed 9 (18%) patients had no residual disease pT0, 7 (14%) pTa, 11 (22%) pT1, 9 (18%) pT2, 11 (22%) pT3, and 3 (6%) pT4.

CONCLUSION

Radical cystectomy remains a complex and morbid procedure with significant complication rate regardless of surgical approach. Using the Clavien reporting system, we identified early complications in 34% of patients, of which five required a significant intervention. Use of this standardized reporting system has allowed us to stratify complications after RARC, allowing easy comparison to other techniques and targeting further reductions in the future.

The learning curve of robot-assisted radical cystectomy: results from the International Robotic Cystectomy Consortium

BACKGROUND

Robot-assisted radical cystectomy (RARC) has evolved as a minimally invasive alternative to open radical cystectomy for patients with invasive bladder cancer.

OBJECTIVE

We sought to define the learning curve for RARC by evaluating results from a multicenter, contemporary, consecutive series of patients who underwent this procedure.

DESIGN, SETTING, AND PARTICIPANTS

Utilizing the International Robotic Cystectomy Consortium database, a prospectively maintained and institutional review board-approved database, we identified 496 patients who underwent RARC by 21 surgeons at 14 institutions from 2003 to 2009.

MEASUREMENTS

Cut-off points for operative time, lymph node yield (LNY), estimated blood loss (EBL), and margin positivity were identified. Using specifically designed statistical mixed models, we were able to inversely predict the number of patients required for an institution to reach the predetermined cut-off points.

RESULTS AND LIMITATIONS

Mean operative time was 386 min, mean EBL was 408 ml, and mean LNY was 18. Overall, 34 of 482 patients (7%) had a positive surgical margin (PSM). Using statistical models, it was estimated that 21 patients were required for operative time to reach 6.5h and 8, 20, and 30 patients were required to reach an LNY of 12, 16, and 20, respectively. For all patients, PSM rates of <5% were achieved after 30 patients. For patients with pathologic stage higher than T2, PSM rates of <15% were achieved after 24 patients.

CONCLUSIONS

RARC is a challenging procedure but is a technique that is reproducible throughout multiple centers. This report helps to define the learning curve for RARC and demonstrates an acceptable level of proficiency by the 30th case for proxy measures of RARC quality.

Robotic assisted radical cystectomy: short to medium-term oncologic and functional outcomes

PURPOSE

To report short- and medium-term oncological and functional outcomes of the first robotic-assisted laparoscopic radical cystectomy (RARC) series from the UK.

MATERIALS AND METHODS

Thirty patients underwent RARC between 2004 and 2007 at our unit. We report oncological and functional outcomes of this procedure in 20 patients (17 ileal conduit and three Studer Pouches), who have completed at least 6 months of follow up.

RESULTS

There were 17 men and three women, median age 66 years (range 38-77 years). Median operating time was 330 min (range 295-510 min), and median blood loss 150 ml (range 100-1150 ml). There were two major complications (10%); a port site bleed and a rectal injury. The median follow up of this cohort is 23 months (range 7-44 months). One patient died of distant metastases at 8 months, and another developed a right ureteric tumour at 7 months. None of the patients had local pelvic or port site recurrence. The overall and disease-free survival are 95% and 90% respectively. Functional complications included a neovesico-urethral stricture at 3 months, a left upper ureteric stricture at 6 months and an incisional hernia at 12 months.

CONCLUSION

Robotic-assisted laparoscopic radical cystectomy is an emerging minimally invasive procedure which at short- to medium-term follow up, in our experience, is oncologically and functionally equivalent to open radical cystectomy.

Delayed bowel perforation following suprapubic catheter insertion

Background

Complications of suprapubic catheter insertion are rare but can be significant. We describe an unusual complication of a delayed bowel perforation following suprapubic catheter insertion.

Case presentation

A gentleman presented with features of peritonitis and feculent discharge along a suprapubic catheter two months after insertion of the catheter.

Conclusion

Bowel perforation is the most feared complication of suprapubic catheter insertion especially in patients with lower abdominal scar. The risk may be reduced with the use of ultrasound scan guidance.
