Laparoscopic hepatic left lateral sectionectomy using the LaparoEndoscopic Single Site approach: evolution of minimally invasive liver surgery

Laparoscopic liver surgery is attracting wider interest for the treatment of benign and malignant neoplasms. Laparoscopy is a safe and feasible approach for lesions located in the left liver lobe. As the emphasis on minimizing the technique continues, single-port access surgery is quickly evolving. We present our initial experience of single-port laparoscopic liver surgery using a LaparoEndoscopic Single Site (LESS) approach with the TriPort System (ASC; Advanced Surgical Concepts, Bray, Ireland) to perform a left lateral sectionectomy via a single supraumbilical incision. The abdomen was approached through a 15 mm supraumbilical incision and a single-port access device was used to perform a left lateral sectionectomy in a patient with a single colorectal metastasis. The total operative time was 145 min, with 50 ml blood loss. Hospital stay was 4 days. Single-port laparoscopic left lateral sectionectomy is a feasible procedure, when performed by experienced laparoscopic surgeons. It has to be determined whether or not this approach would offer benefit to patients, except in terms of cosmesis, compared to standard laparoscopic liver resection.
