Cusimano MC, Simpson AN, Dossa F, et al. - Via performing a systematic review, researchers sought to assess conversion to laparotomy and perioperative complications after laparoscopic and robotic hysterectomy in patients with endometrial cancer and obesity (body mass index, ≥ 30 kg/m²). Searching MEDLINE, EMBASE, and Evidence-Based Medicine Reviews (January 1, 2000, to July 18, 2018), they included 51 observational studies reporting on 10,800 patients with endometrial cancer and obesity (study-level body mass index, 31.0–56.3 kg/m²). Among patients with a body mass index of ≥ 30 kg/m², the pooled proportions of conversion from laparoscopic and robotic hysterectomy were 6.5% (95% confidence interval, 4.3–9.9) and 5.5% (95% confidence interval, 3.3–9.1), respectively, and among patients with body mass index of ≥ 40 kg/m², the respective values were 7.0% (95% confidence interval, 3.2–14.5) and 3.8% (95% confidence interval, 1.4–9.9). They observed similar rates of perioperative complications in correlation to robotic vs laparoscopic hysterectomy in patients with endometrial cancer and obesity. However, because of positional intolerance in patients with morbid obesity, robotic hysterectomy may reduce conversions.
