title: [Comparison of gas and gasless laparoscopy in the treatment of benign ovarian tumors].
abstract: OBJECTIVE
  The aim of the study was to compare the outcomes of the gas and gasless laparoscopy in the treatment of benign ovarian tumors.
  
  
  METHODS
  Retrospective analysis of 48 gas and gasless laparoscopic cystectomies (24 in each group) performed between 2004-2005 in Holy Family Obstetrics and Gynecology Hospital in Warsaw was carried out. An ovarian tumor considered to be benign was the indication to operation. All gas laparoscopies and 25% gasless laparoscopies were performed under general anesthesia. Remaining 75% gasless laparoscopies were performed under epidural anesthesia.
  
  
  RESULTS
  The average time of gasless laparoscopy was 53 minutes and gas laparoscopy 48 minutes. In all cases histopatologic examination during surgery was done. Those assessments revealed that all tumors had been benign. The hospitalization time in both groups lasted to 72 hours after operation. An average blood loss during the surgery, pain felt during the first 24 h after the surgery and the number of complications were similar (statistically insignificant) in both groups.
  
  
  CONCLUSIONS
  Gasless laparoscopic cystectomy is equally efficient and safe as gas laparoscopy. The lack of necessity of producing and maintaining pneumoperitoneum during the surgery was additional advantage of gasless laparoscopy in comparison to gas laparoscopy, because it was possible to perform it in epidural anesthesia.
