ABSTRACT
Objective: To investigate the feasibility of transumbilical single-incision plus one port (SIPOP) robotic total mesorectal excision. Methods: Clinical data of a 70-year-old male patient with BMI 22.1 kg/m(2) who successfully underwent transumbilical single-incision plus 1 port robotic total mesorectal resection of upper rectal cancer at the General Surgery Department of Daping Hospital of Army Military Medical University on September 18, 2019 were retrospectively analyzed. Preoperative colonoscopy revealed that the distance of upper rectal cancer to anal edge was 14 cm, and the tumor size was 2.5 cm×1.5 cm×1 cm. Pathological result confirmed rectal moderately differentiated adenocarcinoma. The preoperative abdominal CT showed thickened bowel-wall of upper rectum and the blurred perirectal fat, suggesting tumor infiltration. Results: The operation was successful. There were no conversion to laparotomy or abdominal auxiliary incision, and the mesorectum of the specimen was intact. The operation time was 165 minutes, the blood loss was about 20 ml, and there were no complications such as injury to peripheral organs. Postoperative pathology showed ulcerative moderately differentiated adenocarcinoma of the upper rectum with TNM stage IVA (T4N2b). The postoperative recovery was smooth. Patient ambulated on the 1st day, the catheter was removed on the 7th day, and discharged from the hospital on the 8th day. Conclusion: The transumbilical SIPOP robotic total mesorectal excision is safe, effective and feasible.
