Robot-Assisted Ileocecal Resection for Cecal Cancer with a Common Trunk of the Middle Colic and Ileocolic Arteries: A Case Report.

INTRODUCTION

Vascular variations around the superior mesenteric vessels increase the technical difficulty and risk of injury during right-sided colon surgery. We report a rare case of cecal cancer with a common arterial trunk formed by the middle colic artery (MCA) and ileocolic artery (ICA) treated by robot-assisted surgery.

CASE PRESENTATION: A man in his 70s was diagnosed with cecal cancer during evaluation for anemia. Preoperative CT revealed that the MCA and ICA originated from a common arterial trunk. Robot-assisted ileocecal resection with lymphadenectomy was performed. After identification of the common trunk, only the ICA was divided following confirmation of the bifurcation. Intracorporeal overlap anastomosis was completed using the double bipolar method.

CONCLUSIONS

Robot-assisted surgery with precise preoperative imaging enables safe management of rare mesenteric vascular variations and provides important educational value.
