[Vacuum-assisted laparostomy for advanced peritonitisis]. / Rol' vakuum-assistirovannoi laparostomy v lechenii rasprostranennogo peritonita.

OBJECTIVE: To evaluate the efficacy of negative pressure therapy in patients with peritonitis. MATERIAL AND METHODS: The study included 127 patients with advanced secondary peritonitis between 2019 and 2022. All patients were divided into 2 groups. All ones underwent staged sanitation of the abdominal cavity. In the first group (n=76), re-laparotomies were accompanied by skin suture only and passive abdominal drainage. The second group included patients (n=51) with open abdominal cavity strategy and negative pressure therapy (vacuum-assisted laparostomy). We analyzed the number of surgeries, postoperative complications, duration of hospital-stay and mortality. RESULTS: In the second group, there were significantly lower morbidity, mean number of surgeries and hospital-stay. In addition, incidence of fascial closure of abdominal cavity was higher and mortality rate was lower in the same group. CONCLUSION: Vacuum-assisted laparostomy in patients with advanced peritonitis can reduce the number of secondary purulent complications and mortality, as well as increase the incidence of fascial closure of abdominal cavity. This approach reduces the number of surgical interventions and duration of in-hospital treatment.

[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.

[Preoperative biliary drainage for malignant biliary obstruction: to drain or not to drain? And if drain, in what way?] / Predoperatsionnaya biliarnaya dekompressiya pri opukholevoi zheltukhe: drenirovat' ili net? I esli drenirovat', to kakim sposobom?

On the basis of the conducted literary search, a number of conclusions can be drawn. When performing preoperative biliary drainage (PBD), it is necessary to have a clear understanding: why is this procedure performed (severe liver failure, cholangitis, long preoperative preparation is required due to comorbid status, neoadjuvant chemotherapy is necessary, etc.)? Routine use of PBD is impractical. In the presence of indications for PBB in perihilar cholangiocarcinoma, percutaneous decompression is preferable, in periampullary tumors, endoscopic. Moreover, both methods can be alternative (for example, in case of technical failure of the first priority). There is also no convincing evidence of the superiority of metal stents over plastic ones for PBD (except in cases of long-term preoperative preparation or neoadjuvate treatment) for periampular tumors. To date, a decrease in overall survival and a higher incidence of implantation metastases have not been proven when using the antegrade PBD method. Large multicenter studies are required with differentiation of patients according to the nosological principle in order to more accurately understand the place of each method, as well as to determine clear indications for PBD and those clinical situations when its implementation is impractical.
