title: Comparison of laparoscopic and open cystectomy for bladder cancer: a single center of 110 cases report.
abstract: OBJECTIVE
  We compared the operative time, complications, blood loss, total cost, and hospital days of laparoscopic cystectomy vs. open cystectomy for bladder cancer.
  
  
  METHODS
  This retrospective, nonrandomized study was conducted between January 2004 and March 2011 on 110 patients (17 women and 93 men) who underwent radical cystectomy for bladder cancer. A total of 45 cystectomies were performed laparoscopically and 65 by open surgery. Mean patient age was 62.9±10.4 years. The age, gender, American Society of Anesthesiologists score, histopathological results etc. were reviewed in this article.
  
  
  RESULTS
  Intraoperative blood loss was significantly lower in the laparoscopic surgery group (821±776 vs. 1112±706 mL, P=0.044) while operative time was significantly lower in the open surgery group (376±90 vs. 445±119 min, P=0.001). The total costs were also significantly lower in the open surgery group 51,726±13,589 yuan (about $8000) vs. 63,053±19,378 yuan (about $10,000), P<0.001). There was no statistically significant difference in complication rates, postoperative days in hospital between the two groups.
  
  
  CONCLUSIONS
  Laparoscopic cystectomy can reduce intraoperative blood loss significantly. Open cystectomy requires less operative time and has a lower cost than laparoscopic cystectomy for bladder cancer. There was no statistically significant difference in postoperative complication rates in the hospital between the two groups.
