Summary
Total laparoscopic hysterectomy (TLH) is a safe and effective procedure for women across all body mass index (BMI) categories. Obesity does not negatively impact outcomes, demonstrating TLH
Area of Science:
- Minimally Invasive Gynecologic Surgery
- Surgical Outcomes Research
- Obesity Medicine
Background:
- Total laparoscopic hysterectomy (TLH) is increasingly utilized for benign gynecologic conditions and early-stage cancers.
- Patient selection for TLH often considers body mass index (BMI), with concerns regarding outcomes in obese individuals.
- Evidence is needed to confirm the safety and efficacy of TLH across the full spectrum of BMI.
Purpose of the Study:
- To evaluate the outcomes, safety, and efficacy of total laparoscopic hysterectomy (TLH).
- To specifically analyze outcomes stratified by body mass index (BMI), with a focus on high-BMI patients.
- To determine if obesity is a contraindication for successful TLH.
Main Methods:
- Retrospective cohort study of 2,266 patients undergoing TLH for benign or early-stage gynecologic malignancies (September 1996 - October 2017).
- Patients were stratified into BMI categories: normal/underweight (<24.9), overweight (25.0-29.9), class I obese (30.0-34.9), class II obese (35-39.9), and class III obese (>40.0).
- Analysis focused on surgical duration, estimated blood loss, complication rates, unplanned laparotomy, and reoperation rates across BMI groups.
Main Results:
- Surgical duration and estimated blood loss were comparable across all BMI classes.
- Obese class II patients demonstrated significantly fewer complications compared to normal BMI patients (OR = 0.27).
- While unplanned laparotomy was slightly higher in class III obese patients, reoperation rates were lowest in class II obese patients and highest in normal BMI patients.
Conclusions:
- Total laparoscopic hysterectomy (TLH) is a feasible and safe surgical option for obese women, irrespective of their BMI classification.
- Obesity should not be considered a contraindication for achieving favorable outcomes with laparoscopic hysterectomy.
- The study supports the use of TLH in a diverse patient population, including those with higher BMIs.
