Objective To evaluate the reoperation of abdominal metastasis after liver resection for hepatocellular carcinoma(HCC).Methods The data of 2748 patients with liver cancer undergoing surgi-cal resection at the Department of Hepatobiliary and Pancreatic Surgery of Li Huili Hospital of Ningbo Medi-cal Center from January 2010 to January 2022 were retrospectively screened.A total of 19 patients with abdominal metastases after liver resection undergoing reoperation were enrolled,which were all males with a median age of 53 years(27 to 68).The surgical procedures and diagnosis for abdominal metastases were recorded,and the recurrence and survival of patients were followed up.Results During the follow-ups of initial resection of HCC,10 patients were diagnosed with postoperative abdominal metastasis by enhanced CT,and seven patients were diagnosed by MRI.MRI and PET/CT were negative in two patients.Abdominal metastasis was found during reoperation in one case and liver transplantation in the other case due to postop-erative liver recurrence.All 19 patients successfully underwent radical resection of abdominal metastases.Eighteen patients underwent open surgery and one underwent laparoscopic surgery.Among them,nine cases underwent simple metastases resection,six combined liver resection,one combined liver resection and right hemicolectomy,one combined partial rectal resection,one combined partial small bowel resection,and one combined liver transplantation.The 1-year,3-year,and 5-year disease-free survival rates were 26.3％,15.8％,10.5％,respectively.The 1-year,3-year,and 5-year overall survival rates were 94.7％,26.3％,15.8％,respectively.Three patients are currently surviving disease-free for 154.3 months,67.3 months,and 33.4 months,respectively.These three patients all had single abdominal metastase and did not receive any targeted or immune treatments after surgery.Conclusion For patients with localized or single abdomi-nal metastases after HCC surgery,reoperation for metastases can bring survival benefits.
