[Preoperative radiation navigation in determining surgical strategy for liver echinococcosis]. / Predoperatsionnaya luchevaya navigatsiya v opredelenii khirurgicheskoi taktiki pri ekhinokokkoze pecheni.

OBJECTIVE: To analyze the technology for diagnostic modeling of liver echinococcosis. MATERIAL AND METHODS: In the Botkin Clinical Hospital, we developed a theory of diagnostic modeling of liver echinococcosis. Treatment outcomes were analyzed in 264 patients who underwent various surgical interventions. RESULTS: A retrospective group enrolled 147 patients. When comparing the results of diagnostic and surgical stages, we identified 4 models of liver echinococcosis. The choice of surgical intervention in the prospective group was based on previous models. Diagnostic modeling reduced the number of general surgical and specific complications, as well as mortality in the prospective study group. CONCLUSION: The technology for diagnostic modeling of liver echinococcosis made it possible not only to identify 4 models of liver echinococcosis, but also determine the most optimal surgical intervention for each of model.

[Selecting the most appropriate surgical treatment of true splenic artery aneurysm]. / Vybor sposoba khirurgicheskogo lecheniya istinnykh anevrizm selezenochnoi arterii.

OBJECTIVE: To analyze the results of diagnosis and treatment of true splenic artery aneurysms. MATERIAL AND METHODS: We analyzed the results of diagnosis and treatment of 27 patients with true splenic artery aneurysm. All ones underwent surgical treatment at the Botkin Municipal Clinical Hospital between 2017 and 2021. Splenic artery aneurysm >1 cm was an indication for surgical treatment. Surgical option depended on aneurysm location. Laparoscopic splenectomy and aneurysmectomy were performed in 4 cases (14.8%), 5 (18.5%) patients underwent endovascular intervention, laparoscopic clipping was performed in 18 (66.7%) cases. Methods of surgical treatment, general and specific postoperative complications according to the Clavien-Dindo and ISGPS classifications were analyzed. RESULTS: Laparoscopic clipping was accompanied by fewer general and specific postoperative complications. Specific complications after laparoscopic splenectomy occurred in 2 patients (BL according to the ISGPS 2016 classification). There was one case of acute pancreatitis after endovascular interventions. In long-term postoperative period, aneurysm recanalization after endovascular intervention was observed in 1 case. CONCLUSION: Surgical treatment of splenic artery aneurysms requires a differentiated approach based on topographic and anatomical assessment of aneurysm relative to the arterial vessel.
