RESUMO
Objective To evaluate the clinical application of Helix water-jet dissector in complex hepatectomy. Methods Clinical data were retrospectively analyzed in 47 patients who received complex hepatectomy using Helix water-jet dissector for the parenchymal division. It was evaluated for the intraoperative blood loss, operation time, postoperative hepatic function and complications in these patients.Results Forty seven patients including 10 cases of hepatic giant cavernous hemangioma, 34 cases of hepatocellular carcinoma, and 3 cases of miscellaneous liver tumors. Among these patients, caudate lobe resection was performed in 6 cases, hepatic segment Ⅵ + Ⅷ resection in 19 cases, segment Ⅳ + Ⅴ + Ⅷresection in 9 cases, segment Ⅷ resection in 5 cases and right hepatic trisegmentectomy in 8 cases. The operation time was (240 ±85) min, intraoperative blood loss was (950 +650) ml, 13 out of 47patients (27.7%) received heterologous packed red blood cell (PRBC) transfusion for more than 2 units per case.Length of stay in hospital was ( 12. 5 ±4. 7) days. Post-operative complications included ascites in 6 cases,hydrothorax in 4 cases, atelectasis in 2 cases and pulmonary infection in 4 cases. No severe complications and death occurred in this group. Conclusion Water-jet dissector may increase operation accuracy,decrease massive blood loss and postoperative complications, therefore, it should be widely used in complex hepatectomy.
