Background:
The choice between single-port laparoscopic hysterectomy (SPLH) and conventional laparoscopic hysterectomy (CLH) remains unclear.
Objectives:
To evaluate the feasibility, safety, and comparative effectiveness of SPLH and CLH.
Search Strategy:
PubMed, Web of Science, and the Cochrane Library were searched in February 2015 using combinations of the terms "single port," "single incision," "single site," "laparoscopic hysterectomy," and "laparoendoscopic hysterectomy."
Selection Criteria:
Randomized controlled trials (RCTs) and retrospective studies comparing SPLH and CLH were included if they reported at least one quantitative outcome.
Data Collection And Analysis:
Study characteristics, quality, and outcomes were assessed. The primary outcomes were procedure failure and perioperative complications. Odds ratio (ORs) and 95% confidence intervals (CIs) were calculated.
Main Results:
Eighteen studies (6 RCTs, 12 retrospective studies) were included. As compared with CLH, SPLH had a higher failure rate (OR 6.37, 95% CI 3.34-12.14; P<0.001). The frequency of perioperative complications did not differ (OR 0.89, 95% CI 0.45-1.74; P=0.73).
Conclusions:
There is no significant difference in the frequency of perioperative complications between SPLH and CLH. However, the higher rate of procedure failure in SPLH should be taken into consideration.
