Background: The study aimed at estimating the effect of body mass index (BMI), used to classify non-obese, obese, and morbidly obese patients, on clinical outcomes in total laparoscopic hysterectomy (TLH) cases. Methods: This retrospective cohort study included 153 patients who underwent TLH for benign, premalignant, or malignant conditions between August 2010 and June 2013. Patients were divided into 3 groups according to BMI, and the following variables were analyzed: operation time, conversion rate, blood loss, total complications, and length of hospital stay. Results: The mean BMI was 33.5 kg/m2 (range, 22-61). Forty-four patients were non-obese (BMI <30), 73 were obese (30≤ BMI <40), and 36 were morbidly obese (BMI ≥40). In 138 patients (90.2%), hysterectomy was performed using an endoscopic technique. The rate of conversion to laparotomy (9.8%; 95% confidence interval (CI), 5.1-14.5), blood loss (70.5 ml; range, 10-700), total complications (5.9%), and length of hospital stay (2.9 d; range, 1-8) did not vary according to BMI. Operation time was longer in obese (p = 0.003) and morbidly obese (0.002) patients than in non-obese patients. Conclusion: TLH could be considered a safe and feasible alternative to abdominal hysterectomy in obese and morbidly obese patients.
