Background: The left lateral segmentectomy (LLS) (segments II and III of Couinaud) is the more frequently carried out laparoscopic liver resection. The objective of this study is to evaluate the feasibility to perform laparoscopic LLS in porcine model and to compare the results with the open technique. Methods: Ten animals were undergone to LLS. In 4 cases the procedure was performed by open technique and in 6 cases by laparoscopy. The operative time, bleeding and weight of the resected liver segment was registered in a prospective database. Autopsy was performed at the seventh postoperative day. Results: The operative time was 77 ± 19 minutes in the open LLS group and 52 ± 38 minutes in the laparoscopic LLS group. Intraoperative bleeding was of 185 ± 67 and 70 ± 52 ml. in the open and laparoscopic LLS group respectively. The weight of the extracted segment was of 128 ± 27 and of 128 ± 16 grams in the open LLS and laparoscopic LLS group respectively. One animal in the open group presented a wound infection. There were no other complications or deaths. Conclusions: Laparoscopic LLS in porcine model is a feasible procedure. Less intraoperative bleeding was observed in the animals operated by laparoscopic technique. The operative time and weight of the specimen is comparable in both techniques. The implementation of this procedure in an animal model could be useful in the development of research, acquisition of laparoscopic skills in liver surgery and implementation of the technique in humans
