Various methods, devices, and techniques have been developed to improve safety during laparoscopic hepatectomy procedures. Among these, the Pringle maneuver PM is widely used to minimize blood loss during liver transections ; however, the risk of ischemic injury associated with this technique is increased by poor hepatic reserve and regeneration dysfunction secondary to liver cirrhosis. This retrospective study evaluated the short-term outcomes and feasibility of precoagulation for endoscopic

Eleven patients with liver cirrhosis who also underwent endoscopic hepatectomy for hepatocellular carcinoma were recruited to undergo either microwave tissue coagulation or radiofrequency ablation for precoagulation before liver transection. A wedge resection without the PM was performed in all patients, with seven patients selected for bipolar radiofrequency ablation and four patients for microwave coagulation therapy. The procedures included video-assisted thoracoscopic hepatectomy in two patients and laparoscopic hepatectomy in nine patients. One patient who underwent radiofrequency ablation developed postoperative bleeding Clavien-Dindo grade . In conclusion, precoagulation can help to minimize intraoperative blood loss without the PM, contributing to effective resection of liver tumors. We propose that precoagulation could serve as a standard technique for endoscopic hepatectomy in patients with cirrhosis.
