Currently, the strategy for preoperative management of patients with malignant obstructive jaundice is not defined. The indications for biliary drainage procedures, the choice of biliary drainage technique and duration of preoperative drainage are still disputable. Analysis of international trials revealed that routine preoperative biliary drainage procedures are not recommended. The indications for biliary drainage in resectable tumors are determined considering severity of obstructive jaundice, cholangitis, dates of major surgery and Bismuth-Corlette tumor type in case of proximal biliary stricture. The choice of retrograde or antegrade preoperative biliary drainage depends on the type of biliary stricture (distal or proximal) and possibilities of medical institution. The majority of studies showed that retrograde (endoscopic) biliary drainage procedures are preferred for distal strictures, antegrade (transhepatic) – for proximal ones. Duration of preoperative biliary drainage depends on normalization of biochemical values. Prolonged drainage may be followed by increased incidence of early postoperative complications. The optimal period of preoperative biliary drainage is 2 weeks. It is necessary to determine the causes of obstructive jaundice as early as possible for successful treatment. This is also essential to define optimal treatment strategy in certain case. Advisability and certain technique of biliary decompression should be determined in accordance with the chosen treatment strategy.

Aim. To analyze complications of percutaneous transhepatic cholangiostomy depending on biliary obstruction level and drainage type.Material and methods. Percutaneous transhepatic biliary drainage was carried out in 974 patients with mechanical jaundice of different genesis. External drainage was predominantly performed for distal obstruction, external-internal suprapapillary – for proximal obstruction. Strictures of biliodigestive anastomosis were managed using percutaneous balloon dilatation and long-term external-internal drainage.Results. Overall morbility was 19.1%. Significant relationship between morbidity and obstruction level, drainage type and tubes quantity was detected. Drainage tube dislocation was the most common drainage-related complication both in proximal and distal obstruction. External-internal transpapillary drainage was followed by suppurative cholangitis and acute pancreatitis in 81.5% of cases. External-internal suprapapillary drainage was accompanied by acute cholangitis in 17.1% of patients and was determined by disconnection of subsegmental ducts that required additional drainage tubes placement. In most cases, complications were corrected by minimally invasive surgery and nonsurgical treatment. Overall mortality was 1.3% (0.3% in cases of distal obstruction and 1.8% in cases of proximal obstruction).Conclusion. Percutaneous transhepatic biliary drainage is a routine non-traumatic method of biliary decompression that may be successfully used irrespective to obstruction level and cause of jaundice. External-internal suprapapillary drainage is preferable for proximal biliary obstruction while external-internal transpapillary drainage should be avoided.

Aim . To compare early and long-term outcomes of laparoscopic and robot-assisted liver resections with open procedures. Material and Methods. Retrospective case-control study was performed. Pseudo-randomization was used to compare homogeneous data. We have assessed survival in patients with various forms of cholangiocellular carcinoma and colorectal cancer metastases after minimally invasive liver resections. Results. For the period 2013–2017 two hundred and fifteen minimally invasive liver resections were performed including 49 robot-assisted and 166 laparoscopic ones. Malignant tumors were in 45% of cases, benign tumors – in 42%, parasitic neoplasms – in 13%. Early results of minimally invasive resections and 70 comparable open liver resections were compared. All procedures were carried out within the same period at one institution. Immediate results were significantly better after minimally invasive liver resections both before pseudo-randomization and after that. There were 60 pairs of patients after pseudo-randomization. In groups of minimally invasive and open resections blood loss was 396 (0–3400) and 853 (20–6000) ml respectively, time of surgery – 319 (85–580) and 376 (180–775) min, incidence of severe (Clavien–Dindo II and over) complications – 10% (n = 6) and 23% (n = 14), length of postoperative hospital-stay – 9 (3–90) and 12 (2–39) days, respectively. 3-year survival after mini-invasive liver resections for colorectal cancer metastases was 70%, various forms of cholangiocellular carcinoma – 40%. Conclusion. Conventional liver resections can be successfully performed in laparoscopic or robot-assisted fashion in certain patients at specialized center of surgical hepatology with sufficient experience in open and laparoscopic liver surgery.

Aim: to assess the role of hepatobiliary scintigraphy for prognosis of hepatic failure after liver resection; to determine threshold index of hepatic uptake of radioactive agent as an indication for surgical prevention of hepatic failure. Material and Methods. The study included 2 groups of patients who underwent hepatobiliary scintigraphy. The 1st group consisted of 50 patients with diffuse liver diseases (chronic hepatitis, liver cirrhosis) in whom histological examination of liver was performed according to METAVIR. 49 patients with liver tumors underwent advanced liver resections (over segments by Couinaud). Results. The highest median of hepatic uptake (2,86) was revealed in patients with liver fibrosis F1, the lowest (2,02) – in patients with liver fibrosis F4. Threshold value of hepatic uptake was 2,4. In 18 patients with hepatic uptake index
