Abstract: The experience of treating 247 patients with obstructive jaundice admitted to the 1st clinic of SamMI in the period from 2010 to 2020 was analyzed. For the differential diagnosis of obstructive jaundice, non-invasive and invasive research methods were used. The efficiency of mechanical lithotripsy reached 86%. The main method for completing percutaneous transhepatic endobiliary interventions, if it is impossible to perform traditional surgical intervention, is endoprosthetics of the bile ducts. When choosing a method of bile removal, it is necessary to take into account the level of obstruction of the biliary tract, the spread of the pathological process and the patient's condition. The two-stage method of treating obstructive jaundice syndrome allowed to reduce the number of postoperative complications by 17%, and the mortality rate to 2.8%.

INTRODUCTION
The problem of treating jaundice of mechanical etiology (obstructive, obstructive, subhepatic) remains one of the most intractable problems of clinical surgery so far [2, 3, 4, 13, 15].
Despite the vast arsenal of modern research methods, differential diagnosis of obstructive jaundice is difficult, and late identification of its true cause leads to a significant delay in performing the necessary surgical intervention. Certain achievements in the treatment of this severe category of patients are associated, first of all, with the introduction of modern (laparoscopic, endoscopic, ultrasound, X-ray television) minimally invasive technologies into clinical practice in medical institutions [1, 3, 4, 10, 17, 18].
MATERIALS AND METHODS
The experience of diagnostics and treatment of 247 patients with obstructive jaundice, admitted to the 1st clinic of SamMI in the period from 2010 to 2020, was analyzed. The patients were between 17 and 81 years old, including 114 women and 133 men.
Traditional surgical treatment of patients with obstructive jaundice complicated by purulent cholangitis, hepatic failure, thrombohemorrhagic syndrome, etc., is very risky and is accompanied by high mortality [5, 8, 9]. Postoperative mortality in patients with non-neoplastic jaundice is 10.4-25.2%, and in patients with neoplastic jaundice it can reach 40% [3, 6, 12]. The high mortality rate after traditional operations performed against the background of prolonged obstructive jaundice required to divide the treatment process in this severe category of patients into two main stages: at the first stage, decompression of the biliary tract using minimally invasive technologies (percutaneous, endoscopic). After a slow elimination of biliary hypertension (rapid decompression is undesirable, as it can lead to worsening liver failure, hemobilia), elimination of endogenous intoxication (by infusion therapy, hemodilution, according to plasmapheresis indications), improvement of the functional state of the liver proceeded to the final second stage of treatment. In recent years, this two-stage approach to the treatment of this severe category of patients has found an increasing number of supporters [7, 9, 11, 14, 16]. In recent years, our widespread introduction into clinical practice of new tactical and technological schemes for treating patients with obstructive jaundice through the use of sparing methods of decompression of the biliary tract and methods of sanitation of the ducts has significantly improved the results of treatment. Indications for the use of one or another method of decompression of the biliary tract using modern minimally invasive technologies (endoscopic, laparoscopic operations, operations from a mini-access,
The most appropriate was the use of endoscopic methods of biliary excretion in cholangiolithiasis (especially choledocholithiasis), lesions of the terminal section of the common bile duct (non-extended strictures, stenosis of BSDK, papillitis, etc.)
RESULTS
The high diagnostic efficacy of ERCP in 192 (77.73%) patients was favorably combined with the possibility of performing therapeutic procedures (papillosphincterotomy, litextraction and lithotripsy, nasobiliary drainage, sanitation of bile ducts, implantation of endoprostheses, etc.) (Table 1).

Therapeutic tactics for choledocholithiasis has now become more active in connection with the development of various methods of litextraction and lithotripsy. Litextraction is indicated for patients with a burdened anamnesis, when it is undesirable to conduct repeated X-ray contrast studies, with the danger of concretions in the terminal section of the CBD, with multiple small stones. The procedure is contraindicated when the diameter of the calculus exceeds the diameter of the CBD and the size of the papillotomy opening. The need for literacy arose in 20.57% of patients. The efficiency of mechanical lithotripsy reached 86%. Nasobiliary drainage with a thin catheter, as a rule, became the final stage of endoscopic interventions. The wide possibilities of nasobiliary drainage have made it possible to increase the efficiency of endoscopic treatment methods and reduce the number of possible complications. Nasobiliary drainage in 66 (23.4%) patients was of great importance for endoprosthesis in 21, treatment of external biliary fistula in 3, cholangiogenic abscesses in 7, aspiration of bile for biochemical, cytological and bacteriological studies, temporary drainage of bile ducts in case of impossibility of arthroplasty in 45 patients. In 47 patients with tumor obstruction of the biliary tract, after a contrast study, PST was performed, and in 21 patients - nasobiliary drainage with endoprosthetics (stenting) of the extrahepatic ducts and separate endoprosthetics of the hepatic ducts. Endoscopic retrograde drainage greatly facilitated patient preparation, without worsening their condition, to subsequent operations on the biliary tract, and arthroplasty was the final stage of treatment in 16 inoperable patients. If it was impossible to use or inexpedient endoscopic methods of decompression and drainage of the bile ducts ("high block" of the bile ducts), percutaneous transhepatic cholangiostomy (PTS) was used in 29 patients under the control of ultrasound and X-ray television. External-internal drainage is the most physiological. The intervention was ended with dosed decompression of the biliary tract under conditions of CChS, followed by the final restoration of the outflow of bile in an operative manner. Dosed decompression of the bile ducts was carried out by adjusting the lumen of the draining catheter. The high level of occlusion in all patients was due to the oncological process and dictated the only possible method of decompression - CChS. In all cases, the aim was to recanalize the tumor with external-internal drainage for subsequent prosthetics or stenting of the CBD. When the lobar hepatic ducts were disconnected, their separate drainage was performed, which was performed in 8 patients. In conditions of purulent cholangitis, preference was given to external drainage until complete sanitation of the bile ducts and antibacterial therapy, taking into
account the association of aerobic and anaerobic microbial flora in 70.1% of cases. In 5 cases of unresectable tumors, external drainage was transferred to external-internal drainage, followed by endoprosthetics. External cholecystostomy is most acceptable in the complex therapy of acute pancreatitis, complicated by obstructive jaundice. Laparoscopic cholecystostomy was performed in 14 patients, percutaneous transhepatic cholecystostomy under ultrasound control - 29. Bile excretion through cholecystostomy with tumor lesion is limited due to possible tumor stenosis of the cystic duct orifice. The main method for completing percutaneous transhepatic endobiliary interventions, if it is impossible to perform traditional surgical intervention, is endoprosthetics of the bile ducts. Endoprosthetics was performed, as a rule, at the second stage (after stabilization of the patient's condition), and in uncomplicated cases it was performed simultaneously with drainage of the bile ducts. Transhepatic endoprosthetics of the bile ducts in 29 patients with obstructive jaundice, caused by unresectable tumors of the hepatopancreatoduodenal zone, was an effective method of internal drainage, representing one of the options for modern minimally invasive technologies, and was considered by us as an alternative to surgical operations in 12 patients. Out of 164 (66.40%) patients with diseases causing acute obstruction of the bile ducts, with the syndrome of painful obstructive jaundice, after stage I - decompression of the biliary system, 137 (83.54%) were subsequently operated on. Treatment of 27 (16.46%) patients was limited to stage I endoscopic surgical interventions (PST - 20 (14.6%), temporary stenting - 7 (5.11%).

was performed after stopping the phenomena of liver failure and normalizing the level of bilirubin in the blood (mean 4.8 days). Laparoscopic cholecystectomies were performed in 63 (28.64%) patients after performing PST, cholelitoextraction. After unsuccessful attempts at endoscopic cholelithotripsy and "fixed" large concrements of the CBD, 44 (32.12%) patients underwent traditional cholecystectomy with intraoperative choledochoscopy, cholelithotomy, and drainage of the CBD in 17 (12.41%), with choledochoduodenoanastomosis in 27 (19.71%) %) of patients. This group of patients was characterized by the largest number of performed radical surgical interventions, of which more than 50% - by the endovideosurgical method. It should be noted that jaundice in these patients quickly gave in to relief as a result of stage I surgical procedures, and the phenomena of hepatic-renal failure were noted only in 17.4% of cases with SVR syndrome (acute pancreatitis, cholangitis, biliary sepsis). Out of 83 (33.60%) patients with diseases causing chronic (tumor) obstruction of the spruce ducts, with the syndrome of painless

CONCLUSION
When choosing bile duct, it is necessary to take into account the level of obstruction of the biliary tract (proximal or distal), the spread of the pathological process to the surrounding organs and tissues and the patient's condition (is it planned to perform radical surgery after drainage of the bile ducts and decompression), the projected life time after minimally invasive intervention, if radical the operation is not indicated, the likelihood of possible complications, material and technical support and the level of preparedness of the surgeon for one or another type of operation.
