Volume 26, Issue 7 / July , 2019

Abstract

Background

The ventral approach differs completely from the caudal approach because of differences in surgical views and the direction of the parenchymal transection.1–4 A three-dimensional (3D) laparoscopy provides the advantages of better depth perception and spatial orientation.5,6 We present a 3D ventral approach with the modified liver-hanging maneuver during laparoscopic right hemihepatectomy (LRH).

Methods

This was a case of a 78-year-old woman with a 4 cm sized cystic tumor located at the right hemiliver. A 3D flexible laparoscope (Olympus Medical Systems Corp., Tokyo, Japan) was used to provide a bird’s-eye view of the surgical field similar to that in an open approach. In the early phase, parenchymal transection was initiated in the cranioventral area of the liver. The liver parenchyma was transected in a ventral-to-dorsal direction. The segment V hepatic vein was dissected and ligated after identifying the main root of the middle hepatic vein. In the late phase, the dorsal area of the liver around the inferior vena cava and the segment VIII hepatic vein were dissected and ligated using the hanging technique.7,8

Results

The operation time was 240 min, with an estimated blood loss of 70 mL. Total pringle time was 30 min. Final pathologic diagnosis was a 4.0 cm sized mucinous cystic neoplasm with low-grade dysplasia. The patient was discharged on postoperative day 7 without any complications.

Conclusion

The 3D ventral approach with the modified liver-hanging maneuver in LRH is a feasible and useful technique because it resembles open right hemihepatectomy with respect to the surgical concept.
