Objective: to develop an effective and safe surgical technique for the treatment of patients with renal cell carcinoma with invasive tumor venous thrombosis of the inferior vena cava (IVC). Materials and methods. The study included 75 patients underwent surgical treatment at the N.N. Blokhin Russian Cancer Research Center between 1995 and 2017. The median age of patients was 57 years (range: 32–72 years). All patients were diagnosed with RCC with invasive tumor venous thrombosis levels II–IV; of them, 55 patients (73.3 %) had complete IVC obstruction and mature venous collaterals. Twenty- seven patients (26.0 %) were diagnosed with regional, 37 (49.3 %) – with distant metastases. Prior nephrectomy was performed in 5 (6.7 %) cases. Surgical treatment included nephrectomy (n = 70; 93.3 %), thrombectomy with IVC resection (n = 75; 100 %), and metastasectomy in solitary distant lesions (n = 11; 14.7 %). Partial IVC resection was demanded in 18 patients (24.0 %): with infrarenal IVC plication – 14 (18.7 %), with reconstruction of IVC with synthetic patch – 4 (5.3 %). Fifty-seven patients (76.0 %) underwent circular IVC resection (with left renal vein (LRV) ligation – 35 (46.7 %)). The IVC was replaced with ePTFE grafts in 4 (5.3 %) patients, IVC reconstruction was not required in 53 (70.7 %) patients. IVC grafting was considered to be justified in patients without mature venous collaterals. Twenty-two patients (29.3 %) received systemic antitumor therapy. Median follow-up was 32.3 months (range: 1–226 months). Results. Median operative time was 237.5 min (range: 135–580 min); median blood loss – 7000 mL (range: 1200–27 000 mL). The post- operative complications rate was 52.1 % (grades III–V – 31.5 %). Hospital mortality was 13.3 % (10 of 75 patients). Thirty-two months overall, cancer-specific, and recurrence-free survival were 42.4 %, 49.5 %, and 61.2 % respectively. At 19 months all prosthesis were patent. None of the patients had glomerular filtration rate <60 ml/min/1.73 m2 after LRV ligation. No patients developed disabling chronic venous insufficiency of the lower limbs after IVC ligation/resection without grafting. Conclusion. Nephrectomy, thrombectomy, and IVC resection is the only effective method of treatment for RCC with invasive tumor venous thrombosis. The development of IVC and LRV venous collaterals allows performing circular IVC resection with LRV ligation without graft replacement.
Malnutrition among surgical patients is rather common problem. The degree and severity of malnutrition after surgery significantly correlates with the length of stay in the intensive care unit and surgical hospital, rate of infectious complications development, unsatisfactory results of treatment and increased costs. The presented clinical recommendations clarifies key methods for the prevention of development, diagnosis and treatment of the protein-energy malnutrition (PEM) syndrome in the pre and postoperative period. The choice of methods for diagnosis and PEM correction during the perioperative period is based on studies evaluated from the endpoints of evidence-based medicine. In applications, key quality criteria for treatment, as well as algorithms of actions in the preoperative and postoperative period are presented.
Недостаточность питания среди пациентов хирургического профиля является распространенным явлением. Степень выраженности нутритивной недостаточности у пациентов после хирургических вмешательств достоверно коррелирует с длительностью пребывания в отделении реанимации и интенсивной терапии (ОРИТ) и хирургическом стационаре, частотой развития инфекционных осложнений, неудовлетворительными результатами лечения, высокими затратами. В представленных клинических рекомендациях подробно изложены ключевые методы профилактики развития, диагностики и коррекции синдрома белково-энергетической недостаточности (БЭН) в предоперационный и послеоперационный периоды. Аргументация выбора методов диагностики и коррекции БЭН в периоперационный период построена на исследованиях, оцененных с позиций доказательной медицины. В приложениях представлены ключевые критерии качества лечения, а также алгоритмы действий в предоперационный и послеоперационный периоды.
Описанный клинический случай острой правожелудочковой недостаточности (ОПЖН), проявившейся при малоинвазивном мониторинге гемодинамики синдрома малого сердечного выброса, демонстрирует вариант развития бивентрикулярной сердечной недостаточности и необходимость проведения расширенного гемодинамического мониторинга у хирургических больных с высоким риском развития послеоперационных осложнений. На сегодняшний день необходимость оценки сердечного выброса у больных в ОРИТ не вызывает сомнений, однако выбор метода мониторинга, предоставляющего дополнительные возможности, составляет одну из немаловажных задач для реаниматолога и может существенно влиять на диагностический поиск причин гемодинамической нестабильности больного. Также данный случай представляет интерес, поскольку не связан с основными описанными в литературе патологическими процессами, приводящими к развитию ОПЖН. Ключевые слова: синдром малого сердечного выброса; острая правожелудочковая недостаточность; бивентрикулярная сердечная недостаточность. HTML
Objective: to assess the early and late functional results of partial nephrectomy in patients with solitary functioning kidney tumors.Materials and methods. Medical data of 131 consecutive patients with solitary kidney parenchymal tumor, who had undergone partial nephrectomy at the N. N. Blokhin Russian Cancer Research Center, were analyzed. The median age was 57 (26–75) years. All the patients were diagnosed with solitary kidney tumor (median RENAL score was 7.0 ± 2.4 and median PADUA score was 9.0 ± 2.2). The median baseline glomerular filtration rate (GFR) was 74 (33–159) ml/min/1.73 m2 (30 (22.9 %) – stage III chronic kidney disease (CKD) and 0 (0 %) – stages IV–V CKD). All the patients underwent partial nephrectomy (with ischemia in 98 (74.8 %) patients, including cold ischemia in 59 (45.1 %)). The median time of ischemia was 24 (7–80) min. The median blood loss was 800 (20–4500) ml.Results. Acute renal injury was recorded in 69 (52.7 %) cases; 6 patients (4.6 %) had indications for acute dialysis. The independent risk factors of acute renal injury were sinus invasion (hazard ratio (HR) 0.08; 95 % confidence interval (CI) 0.03–0.22; p = 0.051), baseline GFR <80 ml/min/1.73 m2 (HR 0.45; 95 % CI 0.22–0.92; p = 0.021), parenchymal ischemia (HR 0.13; 95 % CI 0.05–0.33; p = 0.032), and >500-ml blood loss (HR 0.24; 95 % CI 0.12–0.51; p = 0.005). Progression of previously diagnosed CKD was recorded in 58 (44.6 %) patients; chronical dialysis was required in 2 (1.5 %) patients. The independent risk factors of CKD progression were sinus invasion (HR 0.38; 95 % CI 0.18–0.81; p = 0.002), medial location of the tumor (HR 0.19; 95 % CI 0.09–0.41; p = 0.001), baseline GFR, <60 ml/min/1.73 m2 (HR 0.24; 95 % CI 0.10–0.56; p <0.0001), warm ischemia (HR 0.41; 95 % CI 0.17–1.00; p = 0.052).Conclusion. Solitary kidney resection is associated with a low risk for renal function loss. To achieve optimal functional results, it is desirable to follow the balance between the indications for renal vessel ligation and the need to avoid >500-ml blood loss and cold ischemia.
Введение. Несмотря на переливания свежезамороженной плазмы и тромбоцитов, часто не удается достигнуть нужной «пороговой» концентрации факторов свертывания при массивных кровотечениях. При введении рекомбинантного активированного VII фактора (rFVIIa, эптаког альфа) этот процесс может быть ускорен, происходит «тромбиновый взрыв», который обеспечивает образование стабильной фибриновой пробки. Цель исследования: оценка эффективности и безопасности применения rVIIа в онкохирургии при коагулопатических кровотечениях. Материалы и методы. Обследовано 38 пациентов, оперированных по поводу злокачественных новообразований различной локализации, находившихся на лечении в отделении реанимации и интенсивной терапии № 1 в течение 2014 года. Результаты. Клиническая эффективность rFVIIа составила 94,7% при неэффективности стандартной гемостатической терапии и исчерпанных возможностях хирургического гемостаза при коагулопатических кровотечениях у онкохирургических больных. Заключение. rFVIIа обладает селективным действием (действует в зоне повреждения), что подтверждают данные коагулограммы и тромбоэлаcтометрии. rFVIIа не утяжеляет состояния больных. Introduction. Despite the transfusion of fresh frozen plasma and platelets it is often not possible to achieve the desired «threshold» concentration of coagulation factors in case of acute massive bleeding. Administration of recombinant activated VII factor (rFVIIa, eptacog alfa) can accelerates this process; «thrombin burst» occurs that provides the formation of a stable fi brin plug. Aim: to assess the effectiveness and safety of rVIIa usage in oncosurgery at coagulopathic bleedings. Materials and methods. In intensive care unit during 2014 we examined 38 patients with malignant tumors of various locations after surgery. Results. Clinical efficacy of rFVIIa was 94,7% with ineffectiveness of standard hemostatic therapy and exhausted possibilities of surgical hemostasis with coagulopathic bleedings in oncosurgical patients. Conclusion. rFVIIa has a targeted action (acts in damage area); coagulogram and thromboelometry data prove its action. rFVII does not make patients worse.
Objective. To evaluate short-term and long-term results of nephrectomy, thrombectomy, circular inferior vena cava (IVC) resection in patients with renal cell carcinoma (RCC) and advanced IVC tumor invasion. Materials and methods . Medical data of 49 patients with RCC and level II–IV tumor venous thrombus with advanced IVC wall tumor invasion were analyzed. All the patients underwent nephrectomy, thrombectomy, circular IVC resection (radical – 35 (71.0 %), cytoreductive, in M+ cases – 14 (28.6 %)). Circular resection of the infrarenal IVC segment was performed in 25 (51.0 %) patients; resection of the infrarenal, perirenal and retrohepatic IVC segments with a ligation of the left renal vein (RV) – in 24 (49.0 %) patients. Perirenal IVC prosthesis was used in 2 (4.1 %) patients with initially preserved IVC blood flow, in other cases replacement of the removed IVC segment wasn’t performed due to presence of a network of venous collaterals duplicating the IVC. Patients with metastases received systemic antitumor treatment after nephrectomy, thrombectomy. Results . Median operative time was 260 (135–580) minutes, median blood loss was 8750 (3000–27 000) ml. Severe intraoperative complications were observed in 2 (4.0 %) patients, 1 (2.0 %) patient died on the operating table due to hypovolemic shock. Postoperative complications were observed in 26 (53.2 %) cases (grade III–V in 22 (45.8 %) patients). Five-year overall and cancer-specific survival of all patients was 54.6 and 67.8 %, respectively, relapse-free survival of 35 patients with M0 category was 49.4 %. Both IVC prostheses were patent 12 months after the surgery. Function of the left kidney after ligation of the left RV was preserved at the preoperative level in all 24 patients in a median of 12 (2–120) months. Conclusion. Nephrectomy, segmental/subtotal cavectomy with preservation of the main renal venous entries is an effective treatment method in RCC patients with advanced tumor IVC invasion. The method allows to achieve satisfactory long-term survival rates and functional results.

Aim: to evaluate results of partial nephrectomy for patients with a solitary kidney performed at the N.N. Blokhin Cancer Center.Materials and methods: medical data of 131 patients with solitary kidney tumors underwent partial nephrectomy at the Department of Urology of the N.N. Blokhin Russian Cancer Research Center from 1980 to 2015 were collected. Median age was 57 (26–75) years, a maleto-female ratio was 1:1.2. Median RENAL score was 7.0 ± 2.4. In all cases, chronic kidney disease was initially diagnosed (stage III – 30 (22.9 %), stage IV–V – 0 (0 %)). Median follow-up for all patients was 55 (6–386) months.Results. The rate of intraoperative complications was 9.2 % (12/131), the rate of postoperative complications was 26.9 % (35/131) (severity grade II – 23 (17.6 %), III – 10 (7.7 %), IV – 1 (0.8 %), V – 1 (0.8 %)). Acute renal failure was observed in 69 (52.7 %) cases, acute dialysis was necessary in 6 (4.6 %) patients. Progression of chronic kidney disease was observed in 58 (44.6 %) patients, hemodialysis was demanded for 2 (1.5 %) patients. Histological study revealed renal cell carcinoma in 124 (94.6 %) samples, positive surgical margins were in 2 (1.5 %) samples. No local recurrences in the resection area were observed. Overall 5- and 10-year survival for all patients with renal cell carcinoma was 89.6 and 72.0 %, specific survival was 93.5 and 81.3 %, recurrence-free survival was 85.3 and 62.2 % respectively.Conclusion. Partial nephrectomy is an effective method of treatment in of solitary kidney tumors associated with satisfactory functional and oncological outcome

Objective: to assess the results of nephrectomy, thrombectomy in RCC patients with level III–IV tumor venous thrombosis with and without cardiopulmonary bypass.Materials and methods. Medical data of 167 consecutive RCC patients with level III–IV tumor venous thrombosis underwent nephrectomy thrombectomy in N.N. Blokhin Russian Cancer Research Center between 1998 and 2012 were collected. Right side tumor was in 122 (73.1 %), left side – in 42 (25.1 %), bilateral – in 3 (1.8 %) cases. The extent of thrombus was defined as intrahepatic in 82 (49.1 %), supradiaphragmatic – in 85 (50.9 %) (intrapericardial – in 44 (26.3 %), intraatrial – in 39 (23.4 %), intraventricular – in 2 (1.2 %)) cases. Nephrectomy, thrombectomy with cardiopulmonary bypass was used in 9 (5.4 %), 158 (94.6 %) patients underwent radical nephrectomy with thrombectomy without CPBP and sternotomy. Intrapericardial IVC and right atrium were exposed through transdiaphragmatic approach and providing vascular control over infradiaphragmatic IVC and renal veins.Results. Median blood loss was 6000 (600–27 000) ml. Complications rate was 62.8 %, 90-day mortality – 13.2 %. Intraoperative complications were registered in 80 (47.9 %), postoperative – in 66 (40.5 %) (grade II – 16 (9.8 %), grade IIIb – 1 (0.6 %), grade IVа – 28 (17.2 %), grade IVb – 3 (1.8 %), grade V – 18 (11.1 %)) patients. Modified thrombectomy technique insignificantly decreased blood loss compared to thrombectomy with CPB, did nоt increase complications rate including pulmonary vein thromboembolism, or mortality. Five-year overall, cancer-specific and recurrence-free survival was 46.2, 58.3 and 47.1 %, respectively. Thrombectomy technique did nоt affect survival.Conclusion. In selected patients with mobile thrombi transdiaphragmatic approach allows to avoid the use of CPBP and decrease surgical morbidity without survival compromising.
В онкохирургии выполняют большое количество расширенных комбинированных оперативных вмешательств ввиду распространенности основного процесса или прорастания опухоли в соседние органы. Несмотря на оптимизацию хирургической тактики и анестезиологического пособия, в раннем послеоперационном периоде часто наблюдают кровотечения, которые могут быть обусловлены как коагулопатией, так и исчерпанными возможностями хирургического гемостаза (большая раневая поверхность, зона резекции, резекция поясничных мышц и т. д.). Терапия рекомбинантным активированным УПа фактором способствует снижению времени остановки кровотечения, уменьшению количества трансфузий, дает возможность избирательно действовать на определенные звенья свертывающей системы и влияет на переносимость таких оперативных вмешательств.
Numerous extensive combined interventions have to be performed in oncosurgery because of dissemination of the underlying process - tumor growth to the adjacent organs. Despite optimization of surgical strategy and anesthesiology, hemorrhages often develop during the early postoperative period, because of coagulopathy or because of exhausted potential of surgical hemostasis (large wound surface, resection zone, resection of the lumbar muscles, etc.). Therapy with recombinant factor Vila promotes a sooner arrest of bleeding, a lesser number of transfusions, allows selective modification of certain components of the clotting system, and determines the tolerance of these interventions.
Objective: to identify the predictors of perioperative complications and deaths in surgically treated patients with kidney cancer complicated by venous tumor thrombosis.Subjects and methods. The investigation included data on 463 kidney cancer patients with venous tumor thrombosis. The patients, median age was 57 years. The male / female ratio was 2.5:1. Perirenal, subhepatic, retrohepatic, and supradiaphragmatic tumor thrombi were diagnosed in 161 (34.8 %), 135 (29.2 %), 82 (17.7 %), and 85 (18.3 %) patients, respectively. Regional and distant metastases occurred in 90 (19.4 %) and 145 (31.3 %) cases, respectively. All the patients underwent thrombectomy, retroperitoneal lymphadenectomy; a tumor-affected kidney was removed in 452 (97.6 %) patients.Results. Median surgery duration was 259 (30–580) min; median blood loss was 3500 (100–27 000) ml. The incidence of intraoperative complications was 24.6 % (114 / 463); mortality was 0.9 % (4 / 463). The independent risk factors of intraoperative complications were cranial margin of a tumor thrombus (odds ratio (OR) 1.9; 95 % CI 1.4–2.6; p < 0.0001) and circular resection of the inferior vena cava (OR 5.8; 95 % CI 1.2–27.8; p < 0.0001). The incidence of postoperative complications was 25.7 % (118 / 459);mortality was 6.0 % (28 / 459). Resurgery was required in 31 (6.8 %) cases. Regression analysis identified the risk factors of postoperative complications (highly located cranial thrombus margin (OR 2.6; 95 % CI 1.1–6.4; p = 0.037) and lactate acidosis (OR27.1; 95 % CI 1.2–613.1; p = 0.038), postoperative death (hepatic vein thrombosis (OR 15.6; 95 % CI 4.5–54.3; p < 0.0001),lactate acidosis (OR 23.1; 95 % CI 3.4–158.4; p = 0.001) thrombus removal from the heart (OR 5.0; 95 % CI 2.1–12.2; p < 0.0001)),perioperative death (cranial thrombus margin (OR 1.9; 95 % CI 1.2–3.2); р = 0.007), contralateral renal vein thrombosis (O R 4.4;95 % CI 1.2–15.8; p = 0.025), lactate acidosis (OR 28.4; 95 % CI 4.9–165.1; p < 0.0001), and low creatinine clearance (OR 4.6;95 % CI 1.9–24.9; p = 0.017).Conclusion. Thrombectomy in patients with T3a–cNxMx kidney cancer is a technically difficult intervention associated with the high incidence of complications and death, which must be performed only in specialized centers. The identified risk factors may serve as criteria for predicting the results of thrombectomy.
