Repeat laparoscopic liver resection after an initial open hepatectomy.

ABSTRACT

BACKGROUND: Repeat open hepatectomy (ROH) for recurrent liver tumors is the preferred approach especially after initial open hepatectomy (OH). The aim of this study is to assess feasibility and safety of repeat laparoscopic hepatectomy (RLH) after initial OH in 2 high volume hepato-biliary hospitals. METHODS: Patients were retrieved from prospective data bases from 2012 to 2020. The patients were divided into two groups according to the approach used for repeat hepatectomy, ROH and RLH groups. RESULTS: Sixty-seven patients matched the criteria, 20 in RLH and 47 in ROH. Diagnoses were hepatocellular carcinoma in 52.3%, intrahepatic cholangiocarcinoma in 7.7% and colorectal liver metastases in 40%. Median operative time and blood loss were lower in RLH (199 vs 260 min, and 100 vs 400 ml respectively), as well as overall postoperative complications (20% vs 49%). There were 2 conversions (10%) due to adhesions and one died of postoperative pancreatitis in RLH. Median hospital stay was lower in RLH (5 vs 9 days). CONCLUSION: RLH is a feasible, safe technique and a realistic option to be considered in selected patients after previous OH. Early conversion should be considered when adhesions are more severe than expected.
