Surgical approach to hysterectomy for benign gynecological disease

RHL Summary

13 April 2016
Close-up of a laparoscopic hysterectomy

Key findings

  • No statistically significant differences between abdominal hysterectomy (AH), vaginal hysterectomy (VH) and laparoscopic hysterectomy (LH) in women’s satisfaction and quality of life
  • No data on perioperative mortality and in most of the major long-term complications (pelvic pain, bowel, sexual or pelvic floor dysfunction)
  • VH showed shorter hospital stay compared to AH and LH
  • Statistically, both VH and LH were equally associated with shorter return to normal activities compared to AH, however LH was significantly associated with longer operation time and higher costs.
  • LH was significantly associated with higher risk of urinary tract injuries compared with AH but no statistically significant difference when compared with VH.

Evidence included in this review

The review included 5102 women from 47 randomized controlled trials comparing the effectiveness and safety of vaginal hysterectomy, abdominal hysterectomy and laparoscopic hysterectomy for benign gynecological conditions.

Quality assessment

There was significant heterogeneity in the quality of the included trials with most of them having moderate-to-high risk of bias.

Clinical implications

There is insufficient evidence to make a strong recommendation regarding the optimal surgical management of benign gynecological conditions. However, VH was associated with shorter hospital stay, fewer complications and lower cost than LH or AH and should probably be considered the first option whenever feasible technically. The interpretation of these findings should be considered with caution due to the significant variability in the quality of the trials included the review.

Further research

Further large randomized trials with high quality methodology and power are recommended to inform policy regarding the effectiveness and safety of different surgical approaches to hysterectomy for benign gynaecological conditions. Issues of special relevance to address in future trials include the expertise of surgeons, quality of life and short- and long-term outcomes.

Abstract

Background

The four approaches to hysterectomy for benign disease are abdominal hysterectomy (AH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH) and robotic-assisted hysterectomy (RH).

Objectives

To assess the effectiveness and safety of different surgical approaches to hysterectomy for women with benign gynaecological conditions.

Search methods

We searched the following databases (from inception to 14 August 2014) using the Ovid platform: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PsycINFO. We also searched relevant citation lists. We used both indexed and free-text terms.

Selection criteria

We included randomised controlled trials (RCTs) in which clinical outcomes were compared between one surgical approach to hysterectomy and another.

Data collection and analysis

At least two review authors independently selected trials, assessed risk of bias and performed data extraction. Our primary outcomes were return to normal activities, satisfaction, quality of life, intraoperative visceral injury and major long-term complications (i.e. fistula, pelvi-abdominal pain, urinary dysfunction, bowel dysfunction, pelvic floor condition and sexual dysfunction).

Main results

We included 47 studies with 5102 women. The evidence for most comparisons was of low or moderate quality. The main limitations were poor reporting and imprecision.

Vaginal hysterectomy (VH) versus abdominal hysterectomy (AH) (nine RCTs, 762 women)

Return to normal activities was shorter in the VH group (mean difference (MD) -9.5 days, 95% confidence interval (CI) -12.6 to -6.4, three RCTs, 176 women, I2 = 75%, moderate quality evidence). There was no evidence of a difference between the groups for the other primary outcomes.

Laparoscopic hysterectomy (LH) versus AH (25 RCTs, 2983 women)

Return to normal activities was shorter in the LH group (MD -13.6 days, 95% CI -15.4 to -11.8; six RCTs, 520 women, I2 = 71%, low quality evidence), but there were more urinary tract injuries in the LH group (odds ratio (OR) 2.4, 95% CI 1.2 to 4.8, 13 RCTs, 2140 women, I2 = 0%, low quality evidence). There was no evidence of a difference between the groups for the other primary outcomes.

LH versus VH (16 RCTs, 1440 women)

There was no evidence of a difference between the groups for any primary outcomes.

Robotic-assisted hysterectomy (RH) versus LH (two RCTs, 152 women)

There was no evidence of a difference between the groups for any primary outcomes. Neither of the studies reported satisfaction rates or quality of life.

Overall, the number of adverse events was low in the included studies.

Authors' conclusions

Among women undergoing hysterectomy for benign disease, VH appears to be superior to LH and AH, as it is associated with faster return to normal activities. When technically feasible, VH should be performed in preference to AH because of more rapid recovery and fewer febrile episodes postoperatively. Where VH is not possible, LH has some advantages over AH (including more rapid recovery and fewer febrile episodes and wound or abdominal wall infections), but these are offset by a longer operating time. No advantages of LH over VH could be found; LH had a longer operation time, and total laparoscopic hysterectomy (TLH) had more urinary tract injuries. Of the three subcategories of LH, there are more RCT data for laparoscopic-assisted vaginal hysterectomy and LH than for TLH. Single-port laparoscopic hysterectomy and RH should either be abandoned or further evaluated since there is a lack of evidence of any benefit over conventional LH. Overall, the evidence in this review has to be interpreted with caution as adverse event rates were low, resulting in low power for these comparisons. The surgical approach to hysterectomy should be discussed and decided in the light of the relative benefits and hazards. These benefits and hazards seem to be dependent on surgical expertise and this may influence the decision. In conclusion, when VH is not feasible, LH may avoid the need for AH, but LH is associated with more urinary tract injuries. There is no evidence that RH is of benefit in this population. Preferably, the surgical approach to hysterectomy should be decided by the woman in discussion with her surgeon.
