Overcoming extreme obesity with robotic surgery

Abstract

Background: Obesity is often associated with endometrial cancer and has posed a challenge in surgical management. Complications such as wound breakdown, respiratory challenges, cardiac complications and difficult intubations are associated with obesity. For the patient with uterine cancer, surgery is necessary for staging, control of symptoms and cure. With the advent of the da Vinci(™) intuitive robot, alternative surgical options can now be offered to these patients. While surgery is the principal modality for the treatment and management of uterine cancer, the morbidly obese patient faces increased complications and longer postoperative recovery. As studied in the LAP2, comparable outcomes have been noted in laparotomy vs laparoscopic surgery. Recently, minimally invasive surgery has been refined with the advent of the da Vinci robotic system. Applying a minimally invasive technique further enhanced with the da Vinci robotic system, a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy was performed on a patient with a BMI of 98.

Methods: A 35 year-old G0 woman with a BMI of 98 presented with heavy vaginal bleeding and anaemia. She was diagnosed with endometrioid adenocarcinoma of the uterus, FIGO grade 1. She was treated with a robotically assisted total laparoscopic hysterectomy and bilateral salpingo-oophorectomy.

Results: Her postoperative course was uncomplicated and she was discharged home on post-operative day 1.

Conclusions: Since obesity is a significant risk factor for endometrial cancer and the prevalence of obesity is increasing, developing surgical techniques to appropriately manage these patients is important. Minimally invasive surgery, specifically with robotic assistance, has increased the possibilities of performing minimally invasive surgery in morbidly obese women. It allows navigation around anatomical barriers and decreases the fatigue experienced by the surgeons. With the increasing obesity of our population and the high prevalence of uterine cancer, further advancement of equipment, anaesthesia and surgical techniques to accommodate the larger patient while decreasing complications have yet to be standardized.
