The purpose of the study. To evaluate the immediate and long–term results of the introduction of nerve‑s paring radical hysterectomy into the practice of the center, namely, the frequency of complications, duration of surgery, blood loss, genitourinary disorders and compare the data obtained with the data of the world literature on this issue.Patients and methods. In the period from August 2019 to October 2022, 55 patients diagnosed with cervical carcinoma who underwent nerve‑ sparing radical hysterectomy type III/C1 were treated in the conditions of the regional clinical oncological dispensary. The age category ranged from 31 to 69 years, the average age was 47.3 years. The following postoperative indicators were analyzed: duration of surgery, blood loss, amount of residual urine, duration of hospital stay after surgery, complications, mortality, number of lymph nodes examined. The analysis of long‑term oncological results in patients with a follow‑up period of more than 12 months (42–12 months) was carried out, the frequency of relapses, the frequency of progression, and mortality from progression were estimated.Results. The obtained postoperative averages, such as: the duration of the operation, amounted to 286 minutes; blood loss – 216.1 ml, the volume of residual urine on the 5th day 52.4 ml, the duration of hospital stay after surgery 11.1 days, complications of the II degree according to Clavien–Dindo – 3.6 %, complications of the III degree according to Clavien‑ Dindo – 3.6 %, there was no postoperative mortality, the number of lymph nodes examined was 18.3. During the follow‑up period, the recurrence rate was 0 %, relapse‑free survival was 91 %, progression and mortality from progression were 7 % and 3.5 (4 and 2 patients), respectively. The effectiveness of the implementation of the methodology was evaluated by comparing it with the data given in the world literature on a similar issue. At the same time, it was found that the duration of the operation, blood loss, the frequency of complications and genitourinary disorders, the frequency of relapse and progression did not differ significantly from the data of the international literature.Conclusion. The introduction of the technology of nerve‑ sparing hysterectomy of the uterus type III/C1, in cervical cancer surgery is relatively safe and approachable in a regional oncology hospital.

The use of an artificial circulation and endovascular technologies in the treatment of liver metastases of uveal melanoma is a highly relevant area. Uveal melanoma is a rare cancer from the uveal tract of the eye. The liver is the most common site of metastasis and is affected in 70-90% of cases, being the only site of metastasis in about 50% of cases. Survival ranges from two to three months. This literature review describes the following methods of treatment of liver metastases of uveal melanoma using a heart-lung machine: arterial (arterio-caval), portal (porto-caval), arterio-porto-caval, retrograde arterio-portal. Special attention is paid to the endovascular method of treatment.Literature sources were searched in the following electronic libraries: elibrary.ru, pubmed.ncbi.nlm.nih.gov, researchgate.net.

Background. Metastatic liver injury is a distinct oncological problem, irrespective of primary malignancy. Resection surgery is not always feasible in such patients. Isolated liver chemoperfusion is a promising treatment option in multiple small-focal metastatic organic lesions. This technique is technically complex, which limits its broader evaluation and adoption in clinical practice. The diversity of isolated liver chemoperfusion techniques does not allow an adequate assessment of world experience and requires further research. The important considerations with introducing isolated liver chemoperfusion are: an optimal surgical technique, liver isolation control method, as well as physiological arterial and portal blood flow maintenance.Materials and methods. A total of 21 patients were surveyed over June 2020 — December 2021. The patients were divided into 3 prospective cohorts: A) arteriocaval chemoperfusion, midline laparotomy access, technical-guided liver isolation, B) arteriocaval chemoperfusion, “in J laparotomy” access, ICG-guided liver isolation, C) arterio-porto-caval chemoperfusion, “in J laparotomy” access, ICG-guided liver isolation. A procedure’s tolerance was assessed with: the duration of surgery, postoperative ICU bed-days, total postoperative bed-days, hepatic cytolysis rates, chemotherapy side-effects severity.Results and discussion. The duration of surgery shortened with “in J laparotomy”. Haemotoxicity did not differ between cohorts A and B, albeit appearing significantly lower in cohort C. The cytolytic syndrome duration statistically significantly reduced in C vs. A and B cohorts.Conclusion. All the isolated liver chemoperfusion techniques employed are patient-safe. In ICG-guided liver isolation, the agent leakage into systemic blood flow is less likely, indicating a lower haemotoxicity. Arterioportal isolated chemoperfusion is more physiological compared to other techniques, thus facilitating lower hepatotoxicity. The use of “in J laparotomy” significantly reduces liver mobilisation and vascular cannulation times.

Aim. Analysis of inhospital and long-term outcomes of conventional carotid endarterectomy (CEA) depending on vessel suturing speed.Material and methods. The present prospective multicenter study for the period from March 1, 2017 to October 1, 2020 included 2366 patients who underwent conventional CEA with patch angioplasty. Depending on the time required to apply 1 stitch, 4 groups of patients were formed: group 1 (n=471; 19,9%) — 1 stitch per 2 seconds; group 2 (n=865; 36,5%) — 1 stitch per 3 seconds; group 3 (n=692; 29,2%) — 1 stitch per 4 seconds; group 4 (n=338; 14,3%) — 1 stitch per 5 seconds. The term "stitch" refers to two needle punctures. The follow-up postoperative period was 18,5±11,0 months.Results. There were no deaths and myocardial infarctions (MI) in the inhospital postoperative period. In group 1, anastomotic bleeding (n=93; 19,7%; p

This literature review covers the publications of Russian vascular surgeons in recent years and deals with debatable issues of carotid surgery, including: 1. What is the best technique for carotid endarterectomy (CEA)? 2. Why does restenosis of the internal carotid artery (ICA) develop and how to eliminate it? 3. How to operate on bilateral ICA stenosis? 4. Should carotid glomus be preserved? 5. Is CEA safe in the acute phase of cerebrovascular accident (CVA)? 6. Is CEA safe in elderly patients? 7. How to operate on patients with combined internal carotid and coronary artery involvement? The evidence presented in this publication makes it possible to draw the following conclusions: 1. When choosing a CEA technique, the classical technique with patch angioplasty should be avoided due to the high risk of ICA restenosis. 2. To eliminate ICA restenosis, carotid angioplasty with stenting (CAS) should be used. When performing primary CEA with ICA transposition over the hypoglossal nerve, reCEA can be used 3. In the absence of contraindications, bilateral ICA stenosis can be operated at the same time using CEA. 4. CEA with carotid glomus preservation is the operation of choice in the treatment of patients with hemodynamically significant ICA stenosis due to the elimination of the risks of postoperative hypertension and the formation of hemorrhagic transformation. 5. If there are indications for cerebral revascularization in the most acute period of stroke, CEA should be abandoned in favor of CAS. 6. In old age, CAS is the safest treatment strategy. 7. In the presence of a combined ICA and coronary involvement, the choice of treatment tactics should be carried out only by a multidisciplinary commission, taking into account the risk stratification of adverse cardiovascular events.

Aim. To identify predictors of rethrombosis and death in patients with coronavirus disease (COVID-19) after thrombectomy for acute lower limb ischemia.Material and methods. For the period from April 2020 to January 2022, 189 pa tients with acute arterial lower limb thrombosis and acute lower limb ischemia were included in this study. In all cases, a positive polymerase chain reaction test for SARS-CoV-2 was obtained. According to chest multislice computed tomography, bilateral multisegmental pneumonia was identified as follows: 76 patients — grade 2 (25-50% of lung tissue involvement); 52 patients — grade 3 (50-75%); 61 patients — grade 4 (>75%). Breathing was carried out as follows: in 88 patients — spontaneous; in 42 — with oxygen administration by nasal cannula; 26 — non-invasive ventilation; 33 had artificial ventilation. All acute arterial thromboses developed within the hospital at 4,5±1,5 days after hospitalization. The time between the onset to diagnosis verification was 27,8±5,0 min. The revascularization strategy was established by a multidisciplinary team meeting. The interval between the development of acute ischemia symptoms and surgery was 45,9±6,3 minutes. Thrombectomy was performed according to the standard technique, under local and/or intravenous anesthesia, using 3F-7F Fogarty catheters.Results. Retrombosis developed in 80,4% of cases 6,4±5,1 hours after surgery. In 59,8% of cases, retrombectomy turned out to be ineffective and the patient underwent limb amputation. In 65,6% of patients, a death was established due to multiple organ dysfunction. Among them, limb amputation was performed in 103 patients. Binary logistic regression identified following predictors of retrombosis/ death: age over 70 years (odds ratio (OR), 30,73; 95% confidence interval (CI), 11,52-33,7), obesity (OR, 15,53; 95% CI, 6,41-78,19), diabetes (OR 14,21; 95% CI, 5,86-49,21), vasopressor support (OR 8,55; 95% CI, 4,94-17,93), mechanical ventilation (OR 7,39; 95% CI, 4,81-16,52).Conclusion. Predictors of retrombosis and death in patients with COVID-19 after lower limb arterial thrombectomy are age over 70 years, obesity, diabetes, vasopressor support, and mechanical ventilation.

Uveal melanoma belongs to rare malignant neoplasms, and the biological peculiarity of this tumor determines the high rate of distant metastasis, which reaches 60 %. Most frequently, uveal melanoma metastases are localized in the liver and have an isolated character. At the same time, despite the achievements of modern drug therapy, the treatment results of this category of patients remain unsatisfactory. Among the regional methods of treatment of metastatic uveal melanoma, surgical treatment is considered to be the most effective. Median survival rate in the group of radically operated patients (R0) is 27 months. At present, in the vast majority of cases, surgical treatment is impossible because of multiple bilobar metastasis and advanced cancer process. Median life expectancy of patients with liver metastases is only 9 months. A promising method of regional treatment of inoperable metastatic uveal melanoma is isolated liver chemoperfusion. Multidisciplinary team of Radiology Scientific Research Center and Kostroma Oncologic Dispensary for the first time in Russia presents a clinical case of a patient with isolated inoperable uveal melanoma liver metastases using an innovative method - isolated high-dose chemo hyperthermic liver perfusion with melphalan. The article describes in detail the method of the procedure, estimates immediate (partial response in 1 month after the procedure) and long-term results of the method (stabilization of the condition against the background of immunotherapy in 9 months after surgery). Based on the presented clinical observation, isolated liver chemoperfusion with melphalan for this category of patients is reasonable. However, despite the encouraging immediate results, clinical experience needs to be accumulated in order to be further evaluated in clinical trials.

Introduction. Uveal melanoma is the most common primary intraocular tumor in adults. Despite some achievements in primary tumor treatment, 50% of patients develop distant metastases in various times (3 years to decades). Hematogenous spread is typical for uveal melanoma, and in 90% of the cases liver is the target. Median survival of patients with liver metastases is 4 to 9 months according to various researchers. And the result of treatment is extremely poor, unlike the results of skin melanoma treatment.The aim is to evaluate the immediate results of treatment of patients with uveal melanoma metastatic to the liver using isolated hepatic perfusion technique.Materials and methods. Considering a high risk of developing a metastatic liver disease in patients with uveal melanoma, local therapy is particularly interesting. This article describes the results of 10 metastatic uveal melanoma patients’ Isolated Hepatic Perfusion (IHP) Treatment. IHP was conducted using the standard methods with 100 mg of Melphalan for 60 min.Results and discussion. IHP treatment shows low complication rate. The data for response assessment is available on 9 out of 10 patients, because 10th patient received this treatment less than a month ago. Follow-ups a month after 9 patients underwent IHP showed an objective response to treatment in 6 patients (complete response in 1, partial response in 5 patients).Conclusion. The use of isolated liver chemoperfusion in a small group of patients according to the standard procedure allowed achieving an immediate response in 67% of cases.

The occurrence of tracheal fistulas of ischemic genesis combined with the failure of esophagogastroanastomosis and the communication between them is a rare and formidable complication after esophagectomy with mediastinal lymphadenectomy due to its anatomical position and extensiveness. However, it is insufficiently documented in the literature, both in terms of treatment and in terms of its causes. This observation aims to demonstrate the rare cause of this complication and the atypical successful treatment. In this case, a patient with squamous cell carcinoma G2 of the middle third of the esophagus and TNM stage cT3NxM0. On the McKeown thoracoscopic-laparotomy esophagectomy intraoperatively a short arterial vessel with a diameter of about 3 mm, which passed through the paracancerous infiltration and supplied blood to the esophagus and trachea revealed. The vessel was not isolated from the infiltrate, but was clipped and crossed between the aorta and infiltrate to maintain surgery ablastic. On the 7th day after the operation the insolvency of esophagogastroanastomosis, the fistula of the trachea with mediastinum and the communication between the leak of esophagogastroanastomosis and the fistula of the trachea were diagnosed. We consider this combination as a special case of esophagogastroanastomosis fistula, complicated by the communication between the right pleural cavity and pneumothorax. According to our experience, partial leak of esophagogastroanastomosis successfully heals by secondary tension within 10–15 days against the background of cervicotomic wound drainage and feeding through a nasointestinal tube. In this case there was a leak of saliva in the mediastinum and its penetration into the lumen of the trachea and the right pleural cavity. Surgical diversion of the fistula and stenting of the trachea were considered, but not applied, as the fistula in our opinion was controlled, but the aggressive content of the gastric conduit prevented healing. The patient was on assisted lung ventilation with minimal pressure support and inflow increased oxygen fractio. For this reason, we considered the best stenting of the esophagogastroanastomosis leak area to be covered with a stent in order to stop the aggressive content of the gastric stem from entering the fistula, which led to the successful treatment of the developed severe complication. It should be noted that this method of treatment may be ineffective in patients who need pressure support during ventilation.

Objective: to evaluate complication rate, surgical operation time, mortality rate implementing minimally invasive surgical technique in colon and rectal surgery — a single cancer’s center experience.Matherials and methods. 124 patients underwent surgery in the period from 2016 to 2018 using laparoscopic technique for colorectal cancer. All patients were divided on 3 equal groups, depending on the time required to master laparoscopic technique: group A (1—40 procedure), group B (41—80 procedure) and group C (81—124 procedure). Outcome measures included operation time, mortality rate, readmission and postoperative complication rates, number of lymph nodes removed and time of impatient care.Results. Main outcome variables (operation time, number lymph nodes removed, time of impatient care, mortality rates, postoperative complication rates) reach a plateau in the learning curve after 54 operation. The study showed that the incidence of postoperative complications in all groups was 11.4 %, while the significantly high level of complications was in group A — 17.5 % (p = 0.023). Postoperative mortality in groups A and B was 2.5 % and 2.5 %, respectively.Conclusion. It is shown that the introduction of minimally invasive technologies into colorectal cancer surgery is relatively safe and possible under the given conditions, while the time of mastering the technique is comparable with the data available in the literature.

The authors present to your a en on a rare clinical case of complete intersec on of the superior mesenteric artery in laparoscopic radical nephrectomy. This complica on emerged in the process of learning the technique of laparoscopic radical nephrectomy, before reaching the “plateau” of the learning curve, in condi ons of poor vision and in the interposi on of tissues due to paratumorous infitiltra on. This type of injury has a high risk of total necrosis of the small intestine. However, due to the concerted ac ons of the surgical service and the readiness of surgeons to complete the vascular suture of the main vessels, a successful reimplanta on of the superior mesenteric artery into the aorta was performed. This is confi rmed by postopera ve observa on and examina on, which included CT angiography. It should be noted that descrip ons of cases of aor c reimplanta on of the superior mesenteric artery are extremely rare in the world and national literature, except for cases of mesenteric ischemia. This case contributes to the description of rare cases of aor c reimplanta on of the superior mesenteric artery and shows the correctness of the selected surgical tactics.

OBJECTIVE. The aim of the study is to evaluate the clinical efficacy of isolated hyperthermic liver chemoperfusion with melphalan and tumor necrosis factor alpha when it is isolated bilobate metastatic lesion and the ineffectiveness of systemic chemotherapy in patients with colorectal cancer. MATERIAL AND METHODS. The patient K, 67 y. o., with colorectal adenocarcinoma T3N0M1 (hep, 3 type). liver metastases were detected synchronously with the detection of the primary tumor. Resection of the primary tumor was performed at first, then there was systemic chemotherapy (6 FOLFOX and 3 FOLFIRI). The was tumor progression in liver after second-line chemotherapy. Isolated hyperthermic liver chemoperfusion was perfomed after complete vascular exclusion of the liver with parallel circulation to return blood to the system of the superior vena cava from the inferior vena cava and portal vein. hepatic perfusion in heart-lung machine with the chemotherapy drugs (melphalan and tumor necrosis factor alpha) carried out through the gastro-duodenal artery and back flow to the circulation circuit from the retro-hepatic vena cava. RESULTS. Using of the isolated hyperthermic liver chemoperfusion allowed reaching full necrosis of liver metastases that confirmed by histopathology results and CT data of the abdominal cavity in a month after the procedure. CONCLUSION. Isolated hyperthermic liver chemoperfusion with melphalan and tumor necrosis factor alpha is the effective method of regional chemotherapy, which is advisable in patients with unresectable isolated metastatic lesion of the liver and resistible to systemic chemotherapy.

The authors analyzed the data of 281 cases of iatrogenes of manipulator character in abdominal surgery in order to investigate the circumstances and character of origin. There were 187 cases of operative confirmation and 84 cases of unintentional intraoperative retained foreign bodies. It was detected, that primary planned intervention of higher category of complexity should be related to the high risk group of the development of the operative confirmation. Retained foreign bodies with soft fabric base were diagnosed in early postoperative period as the result of the beginning of postoperative complications. The retained foreign bodies with tough backer material as a rule didn’t cause the complications in early postoperative period. They were diagnosed in long-term postoperative period in majority of cases.
