Perioperative And Oncologic Outcomes Of Right Anterior Sectionectomy For Liver Disease: A Single-Center Experience With 415 Patients

Background Right anterior sectionectomy (RAS) is technically difficult and performed infrequently, so there are few published reports about experiences with this surgery. We describe 10 years' worth of clinicopathologic and oncologic outcomes associated with RAS. Methods We retrospectively reviewed the medical records of 415 patients treated with RAS for hepatic tumors located at segment five and/or eight between January 2008 and December 2017. Results All patients underwent RAS with the alternative Glissonean pedicle clamp and Kelly clamp-crushing methods for transection. The mean operative time was 165 min, and the mean transection time was 28 min. Major morbidity (>= grade III) occurred in 28 cases (6.7%). Bile leakage occurred in 63 patients (15.1%), but no patients required reoperation. Grade A, B, and C post-hepatectomy liver failure occurred in 39 (9.4%), 7 (1.7%), and 0 patients, respectively. There were no in-hospital deaths caused by postoperative complications. The mean hospital stay was 13.3 days. The mean tumor size was 3.8 cm. Among hepatocellular carcinoma (HCC) patients (n = 361, 87.0%), the 5- and 10-year overall survival rates were 78.3%, 64.4%, and the 5- and 10-year disease-free survival rates were 57.2%, 37.7%, respectively. Conclusions RAS was associated with acceptable procedure-related morbidity and mortality as well as appropriate oncologic outcomes for HCC patients.
