Treatment:
We performed a robotic subsegmentectomy of liver
segment III via trocars placed in the lower abdomen (Fig. 2a). A
resection map was preoperatively prepared (Fig. 2b). Surgery was
performed using the intrahepatic glissonean approach in which the S3
Glisson’s sheath was dissected first (Fig. 2c). The liver was then
dissected along the ischemic line (Fig. 2d, e). The operative time was
318 minutes and there was 63 ml of intraoperative blood loss.
Macroscopically, there was a septated and loculated cavity within liver
section III (Fig. 2f). The resection margin was 10 mm.
Microscopically, there were peribiliary glands located around
the cyst. The cyst was lined by a single layer of cylindrical
epithelium without cytological atypia (Fig. 3a, b). This epithelium was
not underlined by an ovarian-like hypercellular stroma, and the
cyst was pathologically diagnosed as a hepatic peribiliary cyst
