Background: An adenocarcinoma of the hepatic colic flexure associated to liver invasion was diagnosed in a 55 year-old woman, who consulted for weight loss and anemia. The patient was submitted to neoadjuvant chemotherapy and, after 4 cycles, an en bloc laparoscopic right hemicolectomy and atypical hepatectomy of segment VI was proposed.
Video: The surgeon stood between the patient’s legs, and the cameraman to the patient’s left. Four trocars were placed in the abdomen. The right mesocolon was opened at the root of the ileocaecal vessels, which were meticulously dissected and clipped. The arterial and venous branch of the middle colic vessels were sectioned as well. The right mesocolon was freed from the duodenum respecting Toldt’s fascia. The proximal transverse colon and the distal ileum were divided by firing of a linear stapler (purple and white loads). Peroperative ultrasonography permitted exclusion of other hepatic lesions and the delimitation of the en bloc resection of segment VI. The hepatic parenchyma was transected using the coagulating hook. A laparoscopic manual side-to-side ileocolic anastomosis by 2 runnings sutures was performed. The mesocolic defect was closed, and the specimen was retrieved through a protected suprapubic incision.
Results: Operative time was 180 minutes and estimated blood loss 150 mL. The patient was discharged on the 5th postoperative day. Pathology evidenced a pT4N1 colic adenocarcinoma. She underwent additional adjuvant chemotherapy, and was doing well at the time of the last office visit.
Conclusion: Advanced colic cancer associated to hepatic invasion can be safely treated by laparoscopy.
