Abstract

It has been reported that parenchyma-preserving hepatectomy (PPH) might lower surgical curability with an increased likelihood of bile duct resection margins (BDRMs). Apparently, PPH is indicated for patients expected to achieve curative resection. The author herein presents a case of a 77-year-old male patient with type IV perihilar cholangiocarcinoma and decreased cardiac function treated with hepatic segments I + IV resection and bile duct resection. During the operation, he underwent two hepatic parenchymal transections matched with right trisectionectomy and left hepatectomy. After removing segments VI and I and extrahepatic bile duct, six hepatic duct openings were exposed at the left and right hila. As some of them were conjoined, two hepaticojejunostomies at the right liver and one hepaticojejunostomy at the left lateral section were performed consecutively. This operation took 7 hours. Eight sessions of intraoperative frozen-section biopsy were performed. All BDRMs were tumor-negative. According to the 8th edition of the American Joint Committee on Cancer staging system, the extent of the tumor was pT2bN2M0. It was regarded as stage IVA tumor. The patient recovered uneventfully. He was discharged on the 18th postoperative day. The patient underwent concurrent chemoradiation therapy and adjuvant chemotherapy. The patient has been doing well without tumor recurrence for the past 24 months to date. In conclusion, PPH can lead to curative resection and improved outcomes through reasonable adjustment of the extent of hepatectomy.
