ObjectiveTo investigate the efficacy of disposable water-cooled non-stick bipolar electrocoagulation for liver resection. MethodsA total of 122 patients with primary liver cancer undergoing elective hepatectomy in our hospital were selected and were divided into observation group and the control group using random number table, with 61 cases in each group. During the operation, the disposable water-cooled non-stick bipolar electrocoagulation was used in the observation group and the conventional unipolar electrocoagulation in the control group. The operation-related indicators (including operation duration, intraoperative blood loss, number of cases with intraoperative blood transfusion and hospital stay), complications during hospitalization (including ascites, bile leakage, hypoproteinemia and intra-abdominal infection) and the liver function indices ［such as albumin (ALB) and alanine aminotransferase (ALT)］ before operation and after 3 days of operation were recorded in both groups. ResultsThe operation duration was longer, but the intraoperative blood loss, number of cases with intraoperative blood transfusion and hospital stay were less in the observation group compared to the control group（P＜0.05）. The ALB levels significantly decreased and ALT levels significantly increased in both groups compared to the preoperative levels（P＜0.05）. After operation, the serum ALB level was higher and the ALT level was lower in the observation group compared to control group(P＜0.05). The total incidence of complications during hospitalization in the observation group was significantly lower than that in the control group (P＜0.05). ConclusionThe disposable water-cooling non-stick bipolar electrocoagulation achieves a significant application effect, and can reduce intraoperative blood loss, can control the proportion of cases with blood transfusion, can reduce the degree of liver function damage, and is beneficial to the prognosis of patients.
