Hepatectomy for metastatic liver tumors complicated with right umbilical portion

, : Hepatectomy for metastatic liver tumors complicated with right umbilical portion. Hepato-Gastroenterology 58(107-108): 984-987

We report the case of a 76-year-old man, presenting with a right umbilical portion (RUP), with two liver metastases of rectal cancer, 2cm and 1 cm tumors in the caudate lobe and anterior segment, respectively. The portal first branch ran to the right posterior segment and the remaining formed a left trunk, thereafter forming RUP. The tumor in the caudate was close to the right posterior segment's Glissonean pedicle. On 3-dimensional CT analysis under tubography via an endoscopic naso-biliary tube, the anatomical patterns of the arteries and bile ducts were complicated. On laparotomy, the gallbladder was located to the left of the round ligament. Right posterior segmentectomy plus partial caudate resection and partial hepatectomy of the anterior segment was performed after skeletonization of the biliovascular structures at the hepatic hilum. Precise examination of the biliovascular structures is needed to safely perform hepatectomy in patients complicated with RUP.
