Hanging maneuver in right hepatectomy for recurrent metastases with diaphragmatic infiltration after radiofrequency ablation: a new indication

Abstract

The liver hanging maneuver is a safe technique to prevent bleeding during transection when a right hepatectomy by an anterior approach, without previous mobilization of the liver, is required. This article proposes a new indication for this technique. The liver hanging maneuver may be useful during right hepatectomy for local recurrence of liver metastases previously treated by radiofrequency ablation (RFA). In these cases, necrosis or fibrosis induced by RFA and local recurrence may cause strong adhesions between liver parenchyma and the diaphragm, thus increasing the risk of bleeding during liver mobilization. Between January 2003 and March 2006, seven patients with recurrent colorectal liver metastases of the right hemiliver, after previous treatment by RFA, underwent right hepatectomy. Liver resection was feasible with the proposed technique in all patients. In four cases, a limited diaphragmatic resection was associated. There was no mortality. Postoperative morbidity was 42.8 per cent. An anterior approach with the liver hanging maneuver for recurrent liver metastases after RFA should be recommended when the metastases are located posteriorly, are not detachable from the diaphragm, and the preliminary mobilization of the right liver may be difficult.
