To evaluate the biological tolerance of the human liver to prolonged warm ischemia, 20 patients who underwent liver resections with hepatic inflow occlusion are reported. Biopsy of liver were performed during and after consecutive periods of hepatic ischemia, and speciments were observed under light and electron microscope. The results showed that hepatic vascular occlusion for ＜30 min, resulted in atotissular temporary but reversible pathologic and ultrastructural changes in liver, even patients with liver cirrhosis had better recovery from the operation when the hepatic ischemia was lengthen up to 40 min.
ObjectiveTo analyze the efficacy and safety of complete excision of the external capsule in the treatment of hepatic echinococcosis.MethodsThe clinical data of 90 patients with hepatic cystic echinococcosis admitted to our hospital from January 2016 to March 2018 were retrospectively analyzed. According to the different surgical methods, this patients were divided into two groups: the partial hepatectomy group and complete excision of the external capsule group, 45 cases in each group. The patient's general condition and the situation during hospitalization were analyzed, and the intraoperative conditions, postoperative complications, recurrence and mortality after one year in different surgical methods were compared.ResultsThe operative time and intraoperative blood loss in the partial hepatectomy group was significantly longer or more than that in the complete excision of the external capsule group (P<0.05), respectively. There was no significant difference between the two groups in hospitalization time (P>0.05). The incidence of postoperative complications was 11.11% in the partial hepatectomy group and 8.88% in the complete excision of the external capsule group. There was no significant difference between the two groups (P>0.05). After 1 year of followed-up, the recurrence rate of the partial hepatectomy group was 4.44%, and there was no recurrence in the complete excision of the external capsule group, and there was no significant difference between the two groups (P>0.05). There was no death in both groups.ConclusionsIn the surgical treatment of hepatic cystic echinococcosis, the most appropriate surgical method should be selected according to the specific conditions of the patient, and the complete excision of the external capsule has higher therapeutic effect and safety in the treatment of hepatic echinococcosis. It is worthy of clinical promotion.
ObjectiveTo improve the calculation method of the sum of residual hepatic lobe volume and total liver volume after partial hepatectomy in rats.MethodsOne hundred and thirty-five SD rats of different body sizes were divided into five groups by completely random design. The body length, tail length, chest circumference, body weight and length of hepatic triangle lobe of the rats were measured before surgery. Then, according to the classic Higgins and Anderson methods, different lobectomies of liver were performed for each group: middle lobe + left inner lobe, left outer lobe, bilateral papillary lobe, triangular lobe, and right lateral lobe were removed; the proportion of theoretical liver resection in each group was 38.1%, 30.1%, 7.9%, 7.8% and 15.3%, respectively. The actual liver resection volume and residual liver volume were measured after surgery. we finally analyzed statistical differences of liver volume calculated by different indirect methods. In addition, the correlation analysis and regression analysis were conducted between the preoperative measured rat body surface parameters and the measured whole liver volume, so as to explore a more simple and accurate volume measurement method.ResultsThe actual proportion of liver resection in each group was 35.0%, 29.2%, 7.1%, 4.9% and 12.0%, respectively. Compared with the residual liver lobe volume actually measured, that calculated by using the indirect method of substitution of the theoretical liver resection proportion was statistically different in all the other four groups except the left outer lobe group. However, there was no statistical difference between the residual liver lobe volume actually measured and that calculated by the actual liver resection proportion in the 5 groups. In addition, in the preoperative measurement of 5 kinds of basic parameters of rats, the body length has the best correlation with whole liver volume, and the regression equation is \begin{document}$\hat Y = - 27.667 + 0.899X$\end{document}.ConclusionsThe liver volume calculated by indirect method using the actual liver resection proportion, compared with the theoretical liver resection proportion, is more accurate. Compared with the body weight, the body length has the better correlation with whole liver volume.
ObjectiveTo investigate the feasibility of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) combined with mixed reality holographic imaging in treating the massive hepatocellular carcinoma.MethodThe clinicopathologic data of 1 patient with massive hepatocellular carcinoma underwent the ALPPS combined with mixed reality holographic imaging in the Guangdong Second Traditional Chinese Medicine Hospital on January 2019 were retrospectively analyzed.ResultsA 58-year-old female patient, the preoperative CT scan and enhanced scan of the abdomen revealed a 12.0 cm×10.5 cm×17.0 cm mass in the right lobe of the liver, with preoperative Child-Pugh grade A liver function. The ALPPS was performed after the preoperative evaluation. The associating liver partition and portal vein ligation was performed and the mixed reality holographic imaging was used during the stage Ⅰ operation. On day 21 after the stage Ⅰ operation, the CT results of the volume of left lateral lobe of liver was approximately 57.64%. On day 24 after the stage Ⅰ operation, the patient underwent the stage Ⅱ operation (radical hepatectomy). The patient received the chemotherapy after the operation. The courses of those operations were successful. And no severe complications occurred after the operation. The postoperative pathological results showed a moderately differentiated hepatocellular carcinoma with multiple foci and a maximum diameter of 13 cm. Six months after the last operation, there was no new intrahepatic metastasis and other metastases were found.ConclusionsALPPS combined with mixed reality holographic imaging is effective in treatment of massive hepatocellular carcinoma. Mixed reality holographic imaging could show anatomical details with three dimensions, it is beneficial for estimating future liver reserve before operation and locating during operation, and there is also a positive significance of postoperative recovery.
ObjectiveTo explore the risk factors for failure of enhanced recovery after surgery (ERAS) in partial hepatectomy. MethodsA retrospective analysis was performed on 344 patients who underwent partial hepatectomy at the Division of Liver Surgery, Department of General Surgery in West China Hospital of Sichuan University from January 2019 to December 2019. All patients were treated with ERAS after partial hepatectomy. Univariate and multivariate logistic regression analysis were used to evaluate the risk factors associated with failure of the ERAS after partial hepatectomy. ResultsA total of 344 patients were included in the study, including 44 patients in the ERAS failure group and 300 patients in the ERAS success group. Multivariate logistic regression showed that combined with chronic diseases [OR=2.32, 95%CI (1.07, 4.93), P=0.03] and intraoperative fluid replacement volume ≤2 475 mL [OR=2.16, 95%CI (1.06, 4.42), P=0.03] were risk factors for failure of ERAS. ConclusionChronic diseases and intraoperative fluid volume ≤2 475 mL are risk factors for the failure of ERAS after partial hepatectomy and can affect prognosis.
