Application of liver three-dimensional visualization technologies in the treatment planning of hepatic malignant tumor / 中华外科杂志

Objective@#To discuss the application of three dimentional(3D)visualization technologies in treatment plan of hepatic malignant tumor.@*Methods@#The clinical data of 300 patients with liver malignant tumor who received treatment from January 2016 to January 2017 in the Third Department of Hepatic Surgery of Eastern Hepatobiliary Surgery Hospital was retrospectively analyzed in this study, including 221 male and 79 female patients aged from 7 to 76 years with median age of 54 years. The median height was 168 cm (115-183 cm), the median weight was 65 kg (20-105 kg) and the median tumor volume was 142 ml (23-2 493 ml). Three-dimensional visualization technology was used in all patients to reconstruct liver three-dimensional graphics. Also, two and three-dimensional methods were taken respectively to evaluate patients and develop treatment strategy. The change of treatment strategy caused by 3D evaluation, actual surgical plan, operation time, time of hepatic vascular occlusion, intraoperative blood loss, volumes of blood transfusion and postoperative complications was observed.@*Results@#After three-dimensional visualization technology was applied, 75(25%) of 300 patients′ treatment strategies had been changed. The range of hepatectomy was extended in 25 patients. And 7 of them were due to hepatic venous variation, which resulted in increasing drainage area. In other 4 patients, liver resections were extended due to lack of perfusion of the liver parenchyma after the removal of portal vein. And hepatectomy was expanded in 14 patients in order to increase the surgical margin. The range of hepatectomy was reduced in 8 patients, 4 of which were due to hepatic venous variation, such as hepatic vein of segment 4 or lower right posterior hepatic vein. The remaining 4 cases were because of insufficient residual liver volume.The surgical resection was performed in 278 cases, 257 of which received operation directly. Left hepatectomy was performed in 24 patients and right hepatectomy was performed in 33 patients. Left trisectionectomy was carried out in 12 patients and right trisectionectomy was carried out in 11 patients. Caudate lobectomy was applied in 10 patients. There were 18 cases of left lateral sectionectomy, 7 cases of right anterior sectionectomy, 25 cases of right posterior sectionectomy and 18 cases of mesohepatectomy. Single or multi segment resection was performed in 99 patients. The treatment strategy of thirty-six patients was converted to staged hepatectomy (ALPPS 11 cases and portal vein embolization 25 cases). The median operation time was 130 minutes (90-360 minutes) and the median inflow blood occlusion time was 20 minutes (0-75 minutes). Median blood loss volume was 200 ml (20-1 600 ml). Thirty-seven of 278 patients received transfusions, and the average red blood transfusion volume was (4.4±1.7)units (0-8 units). Median hepatic resection volume was 530 ml(30-2 600 ml). There were 117 cases of pleural effusion after operation, including 3 patients needing invasive therapy. Ascites occurred in 23 patients, 6 of whom needed invasive therapy. Biliary leakage was observed in 30 patients. Eight patients occurred hepatic cutting surface hemorrhage, 6 of whom received blood transfusion, and 4 of whom underwent laparotomy to stop bleeding. Three patients had pulmonary infection after surgery and 3 patients appeared biliary obstruction. Deep vein thrombosis took place in 2 patients and portal vein thrombosis was observed in 4 patients. No postoperative liver failure and death ever happened in our study group.@*Conclusion@#Three-dimensional visualization technique can optimize the treatment strategy of patients with liver malignant tumor, improve surgical safety.

Objective:To observe the effect of Governor Vessel-unblocking and mind-calming acupuncture on insomnia and further develop the academic idea on Gao’s lineage acupuncture. Methods:A total of 68 insomnia cases were randomly allocated into an acupuncture group (n=34) and a medication group (n=34) according to their sequences of consultation. Patients in the acupuncture group received acupuncture treatment once a day, 5 d a week, for 4 weeks. Patients in the medication group took 1 mg of Estazolam before sleep for each dose, one dose a day, for 4 weeks. Before and after treatment, the sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI), and the efficacy was assessed using the PSQI reductive rate. Results:After treatment, the global PSQI score and scores of each component in the acupuncture group were significantly decreased (allP<0.01). The global PSQI score in the medication group was significantly decreased (P<0.01). Except for sleep disturbance, scores of the rest of components were significantly decreased (P<0.01 orP<0.05). The between-group difference was statistically significant in global PSQI score (P<0.01). Except for sleep latency and duration, scores of the sleep quality, efficiency, disturbance and daytime dysfunction in the acupuncture group were significantly lower than those in the medication group (allP<0.05). In addition, the recovery and marked effect rate in the acupuncture group was significantly higher than that in the medication group (P<0.05). Conclusion:The Governor Vessel-unblocking and mind-calming acupuncture is safe, reliable for insomnia and has better efficacy than Estazolam.
