Laparoscopic surgery is not inherently dangerous for patients presenting with benign gynaecologic pathology. Results of a meta-analysis.
BACKGROUND
Laparoscopic surgery presents a large number of advantages over laparotomy. The goal of this work was to check whether these benefits outweigh any greater risk of complications.


METHODS
The study design was a meta-analysis of published data from prospective randomized clinical trials (RCT). For the period 1966 to June 2000 we searched Medline and Cochrane Controlled Trial Registers and asked the investigators for further details. Meta-analysis was carried out with the Cochrane review manager software RevMan 4.1.


RESULTS
A total of 27 prospective RCT including 3611 women (1809 treated by operative laparoscopy and 1802 treated by laparotomy) were enrolled in the meta-analysis. The overall risk of complications was significantly lower for patients operated by laparoscopic surgery [relative risk (RR) 0.59; 95% confidence interval (CI) 0.50-0.70]. There was no statistically significant difference concerning the risk of major complications with respect to the approach used (RR 1.0; 95% CI 0.60-1.65). The risk of minor complications was significantly lower for patients operated by laparoscopic surgery (RR 0.55; 95% CI 0.45-0.66). Concerning the risks of readmission, second procedure and blood transfusion, there was no difference between the two groups. Identical results were found when we performed a sensitivity analysis including or excluding studies according to the methodological score. Subgroup analysis according to how serious the surgery was (minor, major, advanced) showed a significant increase in the risk of transfusion for advanced procedures performed by laparotomy.


CONCLUSIONS
Laparoscopic surgery is not inherently dangerous for patients presenting benign gynaecological pathologies. The potential risk of complications should no longer be advanced as an argument against using laparoscopic surgery rather than laparotomy for an operation when the indication allows the choice.
