Robotic Low Anterior Resection and Partial Bladder Resection for Management of Locoregional Endometrial Cancer Recurrence

Abstract

To demonstrate a robotic tumor debulking for management of locoregional endometrial cancer recurrence. Case report. Tertiary referral center in New Haven, CT. A 70-year-old patient with a history of stage IB endometrioid endometrial cancer presented with rectal bleeding 3 years after the completion of treatment. A mass involving the distal sigmoid colon/upper rectum and bilateral distal periureteral masses were visualized on imaging. There was no distant metastatic disease. Colonoscopic biopsies were consistent with endometrial cancer recurrence. Because the patient was symptomatic with rectal bleeding and had no distant metastasis, it was recommended that she undergo surgical resection for management of this locoregional recurrence. The patient was placed in reverse Trendelenburg position with a rightward tilt to mobilize the splenic flexure. Once the cephalad aspect of the descending colon mobilization was completed, the patient was placed in Trendelenburg lithotomy position to expose the pelvis. A robot was docked at this point and the pelvic avascular spaces were delineated. A medial-to-lateral approach was used in mobilization of the sigmoid colon mesentery. The left ureter was identified and the sigmoid branches of inferior mesenteric artery were sealed. The descending/sigmoid colon junction was stapled. After complete mobilization of the sigmoid colon, the tumor-free upper rectum was delineated and stapled. Attention was then turned to the distal peri-ureteral masses. The 2-cm mass on the right, which was densely adherent to the distal right ureter, was completely resected after extensive ureterolysis. The resection of the 4-cm mass on the left which involved both the distal left ureter and the bladder dome required an intentional cystotomy and a partial cystectomy to attain negative margins (Supplemental Figure 1). The procedure was continued with the bowel anastomosis. The anvil was introduced through the vagina and was placed into the proximal limb through an antimesenteric incision. An end-to-end tension-free anastomosis was performed and adequate vascularization was confirmed with intravenous indocyanine green. Robotic low anterior resection and partial bladder resection were performed without any complications with negative margins. Robotic tumor debulking should be considered in appropriate patients when managing locoregional recurrence of endometrial cancer [1,2].
