Alveolar echinococcosis (AE) is a rare anthropozoonotic parasitic disease, which can affects the liver, lungs and other organs. R0-radical liver resection is the sole curative therapy for the patients with AE. Size of the parasitic foci, distant dissemination, and involvement of main liver vessels – all this information allows the surgeon to make the right decision about practicability and volume of operation. Formerly, ultrasonography (US) was not method of choice for the qualitative pre-operative diagnostic of AE. Nevertheless nowadays development of new technologies allows US to be an equal to CT and MRI.The aim:to estimate the possibilities of US in the planning of surgery in patients with AE.Materials and methods.The data of 64 patients who were undergone complete liver resection or reduction surgery in A.V. Vishnevsky Surgery Institute in period from January 2008 to December 2016 we respectively analyzed. Specificity and sensitivity of US, CT and MRI were analyzed and ROC-curves were constructed. Statistical significance was calculated using Chi-square.Results.The efficiency of US was significantly comparable to CT and MRI when we analyzed the involved of porta hepatis, vena cava, hepatic veins. Assessment of involvement of liver arteries and vena porta was not statistical significant.Conclusion.Accumulated experience of A.V. Vishnevsky Surgery Institute shows the possibility of qualitative preoperationUS evaluation of AE-lesion, which has to include assessment of distant dissemination and involvement of the liver main vessels. In a big surgical hospitals, which has an experience of AE treatment, pre-operative US can become the method of choice in planning of surgical operation.

INTRODUCTION: Minimally invasive laparoscopic liver surgery is being performed with increased frequency. Lesions located on the anterior and lateral liver segments are easier to approach through laparoscopy. On the other hand, laparoscopic access to posterior and superior segments is less frequent and technically demanding. AIM: Technical description for laparoscopic transthoracic access employed on hepatic wedge resection. TECHNIQUE: Laparoscopic transthoracic hepatic wedge resection on segment 8. CONCLUSION: Transthoracic approach allows access to the posterior and superior segments of the liver, and should be considered for oddly located tumors and in patients with numerous previous abdominal interventions.

We report the first documented case of leiomyosarcoma at zone II-III of inferior vena cava with thrombi in three hepatic veins undergoing ex vivo liver resection and autotransplantation (ELRA) and hepatic veins thrombectomy. A 33-year-old female patient presented with abdominal distention and lower extremities edema. Abdominal wall varicosis and shifting dullness were positive on physical examination. Her liver function was classified as Child-Pugh B and a solid tumor at retro-hepatic vena cava extending to right atrium with thrombi in three hepatic veins were confirmed. The diagnosis of leiomyosarcoma with Budd-Chiari syndrome was highly suspected with preoperative ultrasound, echocardiogram, CT scan, and three-dimensional reconstruction. A zone II-III leiomyosarcoma of IVC origin was confirmed at surgery and ex vivo liver resection and autotransplantation, and hepatic vein thrombectomy with atrial reconstruction were performed under cardiopulmonary bypass (CPB). Operative time, anhepatic time, and CPB time were 12 h, 128 min, and 84 min, respectively. The patients experienced post-operative liver dysfunction and was cured with conservative therapy. Hepatic recurrence two years after surgery was managed with radiofrequency. The patient was alive with liver metastasis three years after surgery. Despite being regarded as an extremely aggressive procedure, ELRA could be considered in the treatment of advanced leiomyosarcoma with Budd-Chiari syndrome and hepatic vein thrombi.

Hanging Maneuver

The philosophy of aggressive surgical approach, its complete implementation in liver trauma surgery did not appear efficient. No matter of permanenent development of diagnostic imaging methods, anesthesia, intensive therapy, medical technology and suture materials, operational theater and operative techniques, major liver resections in trauma had mortality rate up to 60%. With introduction of computerized tomography ( CT,1981) in everyday clinical praxis and with better evaluation of trauma patients, the whole approach to liver trauma patient has been redesigned. Based on AAST - OIS classification, almost 70% of traumatized with grade I,II and III should be treated non - operatively, hospitally, with repeating FAST (focused abdominal ultrasound in trauma) and abdominal CT scans. The rest of traumatized patients, with grade IV and V injuries of juxtahepatic structures demand complexive surgical treatment. The modalities of surgical treatment depend on trauma mechanisms, extensivity, anatomical localization and affection of vascular structures. Hanging Manuevr- the Method of French surgeon Belghiti bases on anterior approach in liver resection is a try for fast solution for fatal bleeding in liver trauma. It consists of placing the elastic cord throughout the anterior surface of VCI or ligamentum venosusm, of upper end of the cord is located in superior part of VCI where hepatic veins are emerging. Lower end of the cord is located in subhepatic part of VCI between 3 Glisonian pedicles. Concerning hepatic veins liver is divided in 3 sections, which derives blood in right hepatic vein RHV, middle hepatic vein MHV and left hepatic vein LHV. Belghiti proposed the usage of hanging maneuver when resecting the right liver, while the cord is placed throughout retrohepatic VCI, lower end between elements of Glisonian pedicle and upper end between hepatic veins. Complications like bleeding from caudal veins are minimal, then speed in liver resection in hemodynamic unstable and ishemic patient, defects like bleeding because compressing tapes or lesions IVC tile mobilazion of liver for conventional resection.

Background: Researching specification and evaluating early results after hepatectomy that it’s used with Sonastar ultrasonic tool. Materials and methods: We prospectively examined data of 19 patients who underwent hepatectomy at Hue Central Hospitalfrom 7/2019to 7/2020. Results: The mean ages was 60,7 ± 10,5 range (19 – 90) and males/females was 6:1.. Patients with solitary liver tumor accounted for 79%; while tumors that have satellite cores accounted for 21% of all cases. 68,4% of all patients have tumor that is more than 5cm in size. Blocking hepatic blood flow by clamping of hepatoduodenal ligament accounts for 57,9%, while right and left hepatic vein clamp accounted for 68,4% and 36,8% respectively. In 78,9% of the cases, surgicel was used to cover the liver resection margin, while the in the remainder 21,5% of the cases, BioGlue was used. Large liver resection (2 and more lobes resected) accounted for 73,7% of all cases. Mean liver resection time was 50 ( 45-110) minutes, mean operation time was 125 (90-280) minutes, mean blood loss amount was 250 (150-650)ml. On average, post-operative time was 8 days (7-23). Post-operative complications was observed in 15,9% of cases, and there was 5,3% deceased. Conclusion: Application of Sonastar ultrasonic tool in hepatectomy reduces blood loss, help better manage hepatic veins, thus reducing complications such as bile leakage. It also helps surgeons manage the liver resection margin, minimalizing recurrences cancer
