Hepatic artery restriction operation combined with ALPPS (HARO-ALPPS), a novel ALPPS procedure for the treatment of hepatocellular carcinoma with severe fibrosis: retrospective clinical cohort study.

BACKGROUND: Associating liver partition with portal vein ligation for staged liver resection (ALPPS) has been used in the treatment of patients with advanced or massive liver cancer without sufficient future liver remnant, but concerns remain regarding tumor outcomes and surgical safety. This study aims to evaluate the efficacy and safety of a new procedure, hepatic artery restriction operation combined with ALPPS (HARO-ALPPS), in the treatment of hepatocellular carcinoma (HCC) patients especially with severe fibrosis. METHODS: This retrospective study analyzed 8 patients who underwent HARO-ALPPS for HCC and compared their outcomes with 64 patients who underwent conventional ALPPS. The primary outcomes assessed were liver regeneration ability (measured by relative and absolute kinetic growth rates), postoperative complications, and mortality. The secondary outcomes included overall survival and disease-free survival. RESULTS: HARO-ALPPS significantly restricted the blood supply of the hepatic artery. One week after surgery, the blood flow of the right hepatic artery dropped to 62.1%. At the same time, HARO-ALPPS shows superior liver regeneration ability, which is particularly prominent in the background of liver fibrosis. No serious complications occurred after HARO-ALPPS. The overall survival rate of HARO-ALPPS was 75%, which was higher than that of ALPPS (64%, P =0.816). CONCLUSION: Compared to conventional ALPPS, HARO-ALPPS exhibits a better liver regeneration ability, and favorable long-term outcomes. Further prospective studies are needed to validate these findings and evaluate the long-term oncologic outcomes of this novel procedure.

Left Hepatectomy Combined with Right Hepatic Artery Resection and Reconstruction for Hilar Cholangiocarcinoma.

BACKGROUND: Hepatectomy combined with hepatic artery reconstruction in the operation for hilar cholangiocarcinoma (Klatskin tumor) is a challenging procedure. We present a video of left hepatectomy combined with right hepatic artery reconstruction for hilar cholangiocarcinoma. PATIENT AND METHODS: The patient was a 60-year-old male who presented with obstructive jaundice. The imaging examination showed that the confluence of left and right hepatic ducts and the wall of common hepatic duct were thickened, the local lumen was narrowed, the intrahepatic bile duct was dilated, and the right hepatic artery was invaded by tumors nearly 2.3 centimeters. Left hepatectomy with total caudate lobectomy, resection with reconstruction of right hepatic artery, hilar lymphadenectomy, and Roux-en-Y hepaticojejunostomy were performed. RESULTS: The operation time was 345 min, and the amount of bleeding was about 400 ml. There was no blood transfusion. The pathology showed poorly differentiated adenocarcinoma, with negative margins of common bile duct and right hepatic duct, and negative results of all lymph nodes. The patient's recovery was uneventful and he was discharged on postoperative day 14. The patient was disease free at 12-month follow-up evaluation. CONCLUSIONS: Hepatic artery resection and reconstruction procedure is safe and feasible for hilar cholangiocarcinoma in a highly tertiary hepatobiliary center.

Hepatectomy and pneumectomy combined with targeted therapy for primary hepatic neuroendocrine carcinoma: Case report and review of the literature.

Primary hepatic neuroendocrine carcinoma (PHNEC) manifests as a rare type of liver tumor. PHNEC is not specifically clinical or radiographical and is often misdiagnosed and mistreated. Here, we present a case report of PHNEC in a 50-year-old woman who was admitted to our department with concealed pain in the right upper abdomen. The initial diagnosis was a probable hepatic space-occupying lesion with tumor bleeding. The patient was subjected to a partial right hemihepatectomy, cholecystectomy, partial resection of the lower lobe of the right lung, partial resection of the diaphragm, and resection of the right perirenal fat sac to alleviate her symptoms. After surgery, gene sequencing was performed to determine the possible cause of the condition. However, five months after discharge, the patient was hospitalized again because of retroperitoneal and peritoneal multiple metastases. Nine months after surgery, the patient died. This case is likely to aid in furthering our understanding of PHNEC to improve the future diagnosis and treatment of this disease.
