Total Laparoscopic Hysterectomy Versus Vaginal Hysterectomy: A Systematic Review and Meta-Analysis

Hysterectomies performed laparoscopically have greatly increased within the last few decades and even exceed the number of vaginal hysterectomies (VHs). This systematic review, conducted according to the Meta-analysis of Observational Studies in Epidemiology guidelines, compares surgical outcomes of total laparoscopic hysterectomy (TLH) and VH to evaluate which approach offers the most benefits. A literature search was performed in PubMed, Embase, and Web of Science for all relevant publications from January 2000 to February 2016. All randomized controlled trials and cohort studies for benign indication or low-grade malignancy comparing TLH with VH were considered for inclusion. From the literature search, 24 articles were found to be relevant and included in this review. The results of our meta-analysis showed no difference between the 2 groups for overall complications (OR 1.24 [.68, 2.28] for major complications; OR .83 [.53, 1.28] for minor complications), risk of ureter and bladder injuries (OR .81 [.34, 1.92]), intraoperative blood loss (mean difference [MD] -30 mL [-67.34, 7.60]), and length of hospital stay (-.61 days [-1.23, -.01]). VH was associated with a shorter operative time (MD 42 minute [29.34, 55.91]) and a lower rate of vaginal cuff dehiscence (OR 6.28 [2.38, 16.57]) and conversion to laparotomy (OR 3.89 [2.18, 6.95]). Although not significant, the costs of procedure were lower for VH (MD 3889.9 dollars [2120.3, 89 000]). Patients in the TLH group had lower postoperative visual analog scale scores (MD -1.08, [-1.74, -.42]) and required less analgesia during a shorter period of time (MD -.64 days, [-1.06, -.22]). Defining the best surgical approach is a dynamic process that requires frequent re-evaluation as techniques improve. Although TLH and VH result in similar outcomes, our meta-analysis showed that when both procedures are feasible, VH is currently still associated with greater benefits, such as shorter operative time, lower rate of vaginal dehiscence and conversion to laparotomy, and lower costs. Many factors influence the choice for surgical approach to hysterectomy, and shared decision-making is recommended.
