[Comparative analysis of side-by-side antegrade stenting and Y-biliary stenting for malignant biliary stricture]. / Sravnitel'nyi analiz antegradnogo stentirovaniia side-by-side i Y-stentirovaniia pri zlokachestvennoi zhelchnoi strikture vorot pecheni.

In the time period from 2009 to 2017 in Botkin Hospital (Moscow) bilateral biliary stenting was performed in 43 patients with malignant common hepatic duct stricture. Patients were divided into 2 statistically homogeneous groups: 'side-by-side' stenting in 28 patients and percutaneous 'Y'-biliary stent placement in 15 patients. The causes of malignant obstruction were as follows: in the 1st group 13 (46.4%) patients with extrahepatic cholangiocarcinoma (46.4%), 8 (28.6%) patients with intrahepatic cholangiocarcinoma, 4 (14.3%) patients with gallbladder cancer, 3 (10.7%) patients with metastatic cancer. In the 2nd group 6 (40%) patients with extrahepatic cholangiocarcinoma, 4 (26.6%) patients with intrahepatic cholangiocarcinoma, 2 (13.3%) patients with gallbladder cancer, 3 (20%) patients with metastatic cancer. Characteristics of patients: age - 1st group 71.2±5.1 years, 2nd group 74.3±5.5 years; sex - (m/f) 1st group 18/10, 2nd group 9/6; location of stricture - 1st group Bismuth IIIa/IIIb 17/11, 2nd group Bismuth IIIa/IIIb 11/4; mean level of bilirubin - 1st group 284±8.2 µmol/l; 2nd group 311±7.4 µmol/l. Technically all procedures were successful (100%). No complications and mortality associated with the procedure was recorded. Clinically significant results were achieved in 26 (92.8%) patients in Group 1 and in 13 (86.7%) patients in Group 2 (p=0.043). Following stenting procedures, 23 (82.1%) patients in Group 1 and 11 (68.8%) patients in the Group 2 had chemotherapy (p=0.047). 19 patients from the 1st group and 10 patients from the 2nd group died due to tumor progression of the underlying disease, other patients are under care of a physician. Median survival rate: 1st group (12 patients - 50 days, 7 patients - 100 days, 9 patients are alive at the time of writing); 2nd group (7 patients - 50 days, 4 patients - 100 days, 4 patients are alive at the time of writing). The results of this study showed that 6 (21.4%) patients from the 1st group and 4 (26.7%) patients from the 2nd group had biliary stent occlusion (p=0.041). The average period of stent function in the 1st group was 78±4.5 days, and 63±4.8 days in the 2nd group (p=0.036). Based on the obtained results, it is recommended to use the 'side-by-side' method of bilobar biliary stenting in patients with malignant common hepatic duct strictures.

[Metal self-expanding stents for malignant obstruction of stomach outlet and duodenum]. / Opyt primeneniia metallicheskikh samorasshiriaiushchikhsia stentov pri zlokachestvennoi obstruktsii vykhodnogo otdela zheludka i dvenadtsatiperstnoi kishki.

AIM: To compare different types of self-expanding stents (partially coated or uncovered) for malignant pyloroduodenal obstruction (MPDO). MATERIAL AND METHODS: 89 MPDO patients underwent stenting at the Botkin City Hospital (Moscow) for the period 2008-2016. The causes of malignant obstruction were: stomach cancer - 53 (59.5%), pancreatic cancer - 31 (34.8%), compression by retroperitoneal lymph nodes - 3 (3.4%), duodenal cancer - 2 (2.2%). Patients were divided into two homogeneous groups. In group 1 (32 patients) partially coated stents were used, in group 2 (57 patients) - uncovered stents. Mean age was 68.3±6.2 and 64.3±5.7 years in both groups respectively; male/female ratio 18/14 in group 1, 32/25 in group 2. Length of stricture was 51±5.1 mm in group 1, 48±4.8 mm in group 2. GOOSS score in group 1: 0-8, 1-13, 2-11, 3-0, in group 2 0-14, 1-25, 2-18, 3-0 (p=0.03). RESULTS AND DISCUSSION: Technical success was achieved in 32 patients of group 1 (100%) and in 57 patients of group 2 (100%). There were no procedure-associated complications and mortality. Clinical success was observed in 29 (90.6%) patients of group 1 and in 50 (87.7%) patients of group 2. GOOSS score of group 1: 0-8, 1-8, 2-10, 3-12, group 2: 0-3, 1-15, 2-19, 3-20. There were 3 distal dislocations of the stent within 1 - days in group 1, in group 2 dislocations were absent. Postoperative chemotherapy was prescribed in 20 (62.5%) patients of group 1 and 38 (66.7%) patients of group 2 (p=0.08). 27 patients of group 1 and 49 patients of group 2 died due to progression of the disease, others are under observation. Mean life expectancy: group 1 (18 patients - 50 days, 9 patients - 100 days, 5 patients were alive by the moment of study); group 2 (32 patients - 50 days, 100 days - 17 patients, 8 patients were alive by the moment of study). 3 patients (9.4%) in group 1 and 7 (12.3%) patients in group 2 had stent dysfunction (p=0.02). Mean period of partially covered stent function was 138±3.9 days, uncovered stent - 96±4.8 days (р=0.003). CONCLUSION: Our study showed that time of stent function corresponds to median survival. Greater number of stent migration in group 1 is due to stent coverage, higher incidence of stent dysfunction in group 2 - due to malignant invasion.

[Efficacy of transcutaneous endobiliary procedures in patients with obstructive jaundice].

Transcutaneous endobiliary procedures (TEP) were performed in 378 patients with obstructive jaundice (OJ). External decompression of the biliary ducts was carried out as the first stage of treatment in all the patients with OJ of various etiology. This procedure led to reduction of cholangitis symptoms and hepatic failure, improvement of general condition of the patients before radical surgery. Endoprosthesis of the bile ducts made in 121 patients allowed physiological passage of bile into the intestine and improved quality of life especially in inoperable patients with hepatic and pancreatoduodenal tumors. During external drainage in 27 (7.1%) patients dislocation of drainage of the common bile duct occurred. Postoperative lethality was 8.5%. After open surgeries 2 (1.2%) patients died.

Results of examination of 324 biopsies from hepatopancreatoduodenal zone were analyzed. The biopsy was performed as roentgentelevision- or US-guided procedure with Pro-Mag 2.2 device. There were no complications. Percutaneous endoprosthesis of biliary ducts was performed in 127 patients (89% of them were older than 65 years) with obstructive jaundice. Roentgen- or gastroscopy-guided hepaticogastroanastomosis was formed in 36 patients with different diseases. The follow-up was to 18 months in malignant tumors, and to 26 months in benign strictures. Video-assisted drainage of gall bladder in acute cholecystitis was performed in 436 patients with cholelithiasis and severe concomitant diseases. Results of many-stage treatment of 207 patients with choledocholithiasis were analyzed, residual disease was revealed in 11 (5.6%) patients.
