Robot-assisted Laparoscopic Excision of Abdominal Wall Endometrioma Utilizing Intraoperative Ultrasound and Transabdominal Needle Placement

In patients with endometriosis, extra pelvic endometriosis is estimated to have an incidence of 11% and a rare subset of extra pelvic lesions include abdominal wall endometriosis with an incidence of 0.03% to 3.5% [1,2]. Evaluation for and surgical management of abdominal wall endometriosis are an essential skill set for the advanced gynecologic surgeon. In this video, we demonstrate a surgical technique for robot-assisted laparoscopic excision of abdominal wall endometriosis with intraoperative ultrasound-guided needle placement.Description and demonstration of surgical technique.A patient with previous history of 2 cesarean sections and right lower quadrant cyclic abdominal wall pain; a tertiary care, academic center.Intraoperative ultrasound-guided needle placement to map location and boundaries of the lesion followed by minimally invasive resection of the lesion with the intermittent advancement and withdrawal of needles to confirm clear margins.Minimally invasive resection of abdominal wall endometriosis using intraoperative ultrasound-guided needle placement is an effective technique to guide surgical dissection and allow for clear surgical margins and successful treatment of this rare condition.
