Robot‐assisted laparoscopic surgery with a fluorescent near‐infrared ray ureteral catheter for a rectal cancer patient with pelvic kidney: A case report

Abstract

An 85‐year‐old woman presented with a stomachache after a meal and was admitted to the previous clinic. Multi‐detector computed tomography (CT) of the abdomen showed wall thickening in the rectum and right ectopic pelvic kidney. Colonoscopy revealed a mass at the rectum, and a biopsy showed adenocarcinoma. CT showed no lymphadenopathy or distant metastasis. Hartmann's procedure with fluorescent near‐infrared ray ureteral catheters was used to avoid causing urinary injury. Robotic surgery was performed while checking the route of the ureter in near‐infrared mode. The patient was discharged on postoperative day 14 without specific complications. This case appears to be the first of robot‐assisted laparoscopic surgery for a rectal cancer patient with pelvic kidney.

Robot‐assisted low anterior resection in a patient with rectal cancer who had a urinary reservoir: A case report

“…Using these functions, even highly complex surgeries can be performed safely 8,9 . Hasegawa et al showed that robotic surgery is beneficial for procedures such as pelvic kidney surgery, where the surgical field of view is obstructed by organs, especially due to the ability to eliminate the physical interference of the forceps thanks to their articulated function 10 . Moreover, in our case, the benefits of using ICG were especially valuable.…”

The local injection into the mucosa near the tumor not only pinpointed the tumor but also highlighted the lymphatic vessels within the mesorectum.…”
