Indocyanine Green Fluorescence Imaging-Guided Laparoscopic Right Posterior Sectionectomy with Glissonean Approach and Modified Hanging Maneuver.

Background: In the era of innovating minimal invasive surgery, laparoscopic right posterior sectionectomy (RLPS) is considered a technically challenging procedure for its deeply anatomic location. Performed by experienced surgeons, it has been shown to be a safe and feasible procedure. The purpose of this video was to show the technique of a RLPS.

Methods: This is the case of a 70-year-old man who was treated for a mid-rectum adenocarcinoma with two synchronous liver metastases located in the posterior sector of the right liver. Tumor board decision was chemoradiotherapy followed by a simultaneous rectal and hepatic surgery.

Results: An extrahepatic Glissonian approach of the right posterior pedicle was performed. After selective clamping of the right posterior pedicle and injection of indocyanine green, the right portal fissure between the two sectors of the right liver appeared. The parenchymal transection performed in a caudal approach, along a perfectly marked plane. One metastasis was in contact with the right hepatic vein. Because R1 vascular surgery has demonstrated similar oncological outcomes to R0 resection, we detached the metastasis from the vein to preserve a good venous drainage of the remaining right liver. The procedure was completed with a laparoscopic anterior resection of the rectum. The duration of the liver resection was 200 min, and blood loss was 300 ml. Postoperative course was uneventful, and the patient was discharged on postoperative Day 10.

Conclusions: Laparoscopic right posterior sectionectomy is a safe and feasible procedure. However, it is technically challenging and requires advanced experience in liver and laparoscopic surgery..
