Results of the study and their discussion. It is advisable to distinguish four groups of patients with acute and chronic cholangitis: I group. The pathological process is localized only in the lumen of the main ducts. Surgical tactics of treatment of these patients is urgent endoscopic papilosphincterotomy (EPST) and clearence of the ductal system. II group. The walls of the main bile ducts are involved in the pathological process, which led to their deformation and stricture. The vast majority of operations in this group are the reconstruction of the biliary tree. III group. Patients with chronic recurrent cholangitis who have already undergone biliary reconstruction, but which did not prove to be effective or was complicated by various types of new strictures. IV group. Patients with obstruction of the biliary tract caused by a cause localized outside the biliary system. In these patients, as a rule, the phenomena of cholangitis are mild, and the manifesting symptoms are biliary hypertension and liver failure. Conclusions. The use of the proposed classification, based on the pathogenetic features of the development of cholangitis in various pathomorphological conditions, makes it possible to clearly define the issues of surgical tactics.","PeriodicalId":405037,"journal":{"name":"Kharkiv Surgical School","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134262056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem of tumor lesions of the colon remains one of the main in clinical medicine due to the widespread prevalence and tendency to increase colorectal cancer (CRC), the lack of effective methods for preventing and treating dangerous complications that often develop. \u0000Aim. The improvement of the results of surgical treatment of patients with CRC by studying the possibilities of video laparoscopy and choosing the optimal tactics based on assessing the severity of the condition and cytokine status of the patient. \u0000Material and methods. The results of treatment of 155 patients with CRC who were treated at the clinic of the State Institution “Zaitsev V.T. IGUS of the National Academy of Medical Sciences of Ukraine”, which is the clinical base of the Department of surgery #1 of KhNMU, were studied. When choosing treatment tactics for patients, the stage of the tumor lesion, the level of acute intestinal obstruction (AIO), the level of endogenous intoxication assessed on the APACHE II and SAPS severity scales, as well as the state of the immune system – on the level of IL-6 in the blood were taken into account. \u0000Results. In all cases, the nature and time of preoperative preparation was determined based on the study of clinical and laboratory parameters of the IL-6 level in the blood serum, as well as a point assessment of the severity of the physiological state of patients on the APACHE II and SAPS integral scales. With the correct selection of patients, laparoscopically assisted operations were performed, which give a lower percentage of complications, a more favorable postoperative period, and a shorter hospitalization period than traditional operations. Thus, in emergency patients, intestinal motility appeared on the third day after surgery (3.85±0.11), and gas discharge began 4 days later (4.33±0.04), the appearance of independent emptying was noted on the fifth day after surgery. \u0000Conclusions.

To analyze the results of surgical treatment of patients with chronic ischemia of the lower extremities after using modern types of surgical approaches and technologies in the short term. \u0000Materials and methods. The results of surgical treatment of 420 patients were studied. Since 2019, 198 patients (the main group) have been treated using the updated ESVS international guidelines. Both groups of patients (the main group and the comparison group) were comparable in terms of sex, age, location of the lesion, and type of surgical intervention. \u0000A total of 98 (23.3 %) patients were operated on by the open method, 243 (57.9 %) by the endovascular method, and 79 (18.8 %) by the hybrid method. We studied such indicators as: postoperative thrombosis, limb amputations, mortality, as well as repeated operations performed due to complications or unsatisfactory results of the primary operation. \u0000Results and their discussion. The most recent results of surgical interventions revealed that the largest number of complications was found in the group of patients with multilevel occlusive-stenotic lesions of arteries, which correlates with the data of international studies. The direct effectiveness of endovascular interventions is higher than that of open revascularization and hybrid operations, and the trauma of miniinvasive endovascular techniques is significantly less compared to the methods of open reconstructive surgery. \u0000When analyzing the short-term results of surgical interventions, it was found that the largest number of complications was found in the group of patients with multilevel occlusive-stenotic lesions of arteries.
