Aim: comparative analysis of peri-operative results of laparoscopic and open liver resections for hepatocellular carcinoma.Matherial and methods. A retrospective analysis included 73 patients with hepatocellular carcinoma who underwent liver resection from 2014 to 2019. In patients with liver cirrhosis contraindications were: 2 degree of varicose veins of eosophagus, severe ascites, liver cirrhosis class B and C (Child–Pugh)Results. Average operation time in comparing groups did not differ. Bloodloss (502 ml and 1380 ml), frequancy of complications by Clavien–Dindo (32.6% and 55.5%), duration of post-operative hospital stay (8 days and 13,6 days) were significantly less in the group of patients with laparoscopic liver resection (р < 0.05). In the early postoperative period, 2 (2.7%) patients died due to sepsis and posthepatectomy liver failure. There were no fatal outcomes in the group of laparoscopic liver resections.Conclusion. Laparoscopic liver resections for hepatocellular c...

Цель работы. Сравнительный анализ выживаемости после открытых и лапароскопических резекций печени методом псевдорандомизации на основе опыта двух крупных отечественных центров хирургической гепатологии. Материал и методы. Первичной точкой исследования была оценка отдаленной общей и безрецидивной выживаемости после лапароскопических и открытых резекций печени. Непосредственные результаты оценивали вторично. Псевдорандомизация была использована для выравнивания показателей в группах с целью уменьшения недостатков, присущих обсервационным исследованиям. Результаты. Анализировали данные 185 больных: 93 выполнили лапароскопическую резекцию печени, 92открытую. Ближайшие результаты лечения рассмотрены у 176 (95%) больных, отдаленные результатыу 157 (85%). Метод псевдорандомизации применен на выборке из 157 пациентов. В результате выравнивания групп сформированы 43 пары. До применения псевдорандомизации кровопотеря и продолжительность стационарного лечения были меньше в группе лапароскопических резекций печени. После выравнивания групп различия нивелировались по кровопотере. Продолжительность лечения в стационаре осталась достоверно меньше после псевдорандомизации исходных показателей. Не получено различий в частоте тяжелых осложнений. Летальных исходов не отмечено. Общая пятилетняя выживаемость в группах лапароскопических и открытых резекций печени не отличалась до выравнивания (56 и 68%) и после (72 и 76%). Безрецидивная пяти-и четырехлетняя выживаемость также не отличалась, но имела тенденцию к большей продолжительности после лапароскопических резекций печени до и после выравнивания (52 и 10%; 58 и 28%). Заключение. Лапароскопические резекции печени по поводу метастазов колоректального рака приводят к уменьшению сроков стационарного лечения. Общая выживаемость пациентов не зависит от варианта доступа. Безрецидивная выживаемость имеет тенденцию к улучшению после лапароскопических резекций печени.

Rationale: Until now, safety of minimally invasive liver resection (MILR) has not been studied sufficiently.Aim: To assess immediate results of MILR and open type resections in patients with colorectal metastases, performed in the Russian center of surgical hepatology specialized at implementation of minimally invasive techniques.Materials and мethods: This was a retrospective observational case-control study. Patients who underwent surgery for isolated liver metastases of colorectal cancer in a single center from October 2013 to February 2018 were included into the study.Results: As per December 2017, over 500 resections have been performed in the study center, including 226 MILR. One hundred two patients underwent open resection and MILR for colorectal metastases. From 83 patients enrolled into the study, 51 (61%) had MILR, including 7 robotic MILR. The open resection and MILR groups did not differ in terms of gender, age, ASA score, primary tumors location and stage by the time ...

Curtitoma nodulosa (Krause, 1885) comb. nov., a rare species that was found only in the bays of the Chukotka Peninsula. Firstly it was described as Bela violacea var. nodulosa Krause, 1885, secondly-as Lora inequita Dall, 1919. It differs from Curtitoma violacea (Mighels et Adams, 1842) by the presence of well-defined axial folds, nodes on the keels, and a dagger-like type of radular teeth. From other members of genus Curtitoma Bartsch, 1941 it differs by the presence of keels. The specimens of «Oenopota inequita Dall, 1919» from the Sea of Japan [Bogdanov, 1990] belong to another species of genus Obesotoma Bartsch, 1941. It is proposed to consider Curtitoma nodulosa as a valid name, and Lora inequita as its junior synonym.
Malignant tumors cells are disseminated from primary focus are disseminated to secondary organs by sanguineous or lymfogenous way producing metastasis. The presence of metastasis in liver is important factor in survival prognosis. Vascular rich networks formed by metastases, disorganize classical liver hemodynamics model. Metastases blood supply is provide by portal vein in the beginning. When metastases will increase, the blood supply is performed by hepatic artery. The difference between normal or infiltrated liver blood flow, because of neovasular inducing are important factor for metastases detecting: - reduced portal blood flow because of increased vascular resistance due tumor volume compression. - increased blood flow through the hepatic artery results of decreased vascular resistance because of new created vascular grid. The aim of the study is to estimate value of color Doppler duplex ultrasound in early detection of liver metastases, measuring hepatic artery flow volume an...

Цель работы – обзор современных данных о возможностях трансабдоминального ультразвукового исследования (УЗИ) в диагностике заболеваний кишечника, а также представление собственных результатов по совершенствованию эхографической визуализации стенки тонкой и толстой кишки. Существуют следующие основные варианты методики трансабдоминального УЗИ кишечника: 1) без какой-либо специальной подготовки, причем исследование лучше проводить натощак, но в неотложной гастроэнтерологии возможна эхография после еды; 2) энтероклизис; 3) контрастирование тонкой кишки; 4) ультразвуковая ирригоскопия; 5) УЗИ опорожненного от содержимого кишечника после очистки толстой кишки раствором поли-этиленгликоля (ПЭГ), принятым внутрь (как для колоноскопии); 6) контрастирование тонкой и толстой кишки раствором ПЭГ, принятым внутрь. Наилучшая визуализация стенки кишки отмечена при использовании двухэтапного применения ПЭГ, когда осуществляется вечерний прием поло-вины дозы ПЭГ, утром проводится УЗИ, а затем прием...
Parenchymatous-Stromal Ratio in Colorectal Cancer Tumors as an Indicator of Metastasis
Oncologia i radiologia Kazakhstana
Relevance: Colorectal cancer (CRC) is one of the five most common cancers worldwide and is characterized by trends in incidence, disability, and mortality. A significant recurrence rate and early metastasis characterize CRC. Many meta-analyses in the world literature are aimed at finding factors that determine the probable outcome of the disease. ДИАГНОСТИКА Онкология и Радиология Казахстана, №3 (69) 2023 37 The study aimed to evaluate the role of the parenchymal-stromal ratio in the progression of colorectal cancer. Methods: When microcopying at 40x magnification, the parenchyma (Sp) and stroma (Sm) area were measured in the areas of superficial tumor growth and deep invasion. The parenchymal-stromal ratio (PSR) was calculated using the formula PSS=Sp/Sm, and the correlation with tumor metastasis was determined. Results: With an increase in the depth of tumor invasion, the frequency of metastasis to the liver also increased. The metastasis rate for invasion into the muco-submucosal...
Metabolism and Microstructure of the Small Intestine Wall in Patients With Colorectal Cancer
Russian Sklifosovsky Journal "Emergency Medical Care"
RELEVANCE In patients with colorectal cancer (CRC), the normal small intestine, located outside the pathological focus, undergoes changes that may be the cause of digestive dysfunction after radical surgery to remove the tumor.The assessment of metabolic and microstructural changes in the ileum mucosa in patients with colorectal cancer is necessary to correct the algorithms of postoperative therapy and enteral nutrition. Modern means of optical bioimaging are potentially capable of solving this complex diagnostic problem.AIM OF STUDY To study the features of metabolism and morphological structure of the wall of a conditionally normal small intestine in the mucosa in patients with stage 1–3 CRC using macro- FLIM and optical coherence tomography (OCT).MATERIAL AND METHODS The object of the study was the wall of the ileum (66 samples) from the mucosal side of patients with histologically confirmed CRC stages 1–3 with tumor location in the right sections of the colon. Eight samples were...
Ultrasonic Diagnostics at the Stages of Liver Echinococcois Treatment
Journal of Experimental and Clinical Surgery
Cystic echinococcosis is a chronically severe parasitic disease of humans and animals caused by parasitism of the larval stage of Echinococcus unicameral.Ultrasound (ultrasound) being the most widely used option of visual diagnostics is the leading method of radiological diagnosis of echinococcosis of the liver and other organs. The technique is generally available and allows diagnosing echinococcosis at a stage when parasitic cysts are still small in size, starting from 1.5-2 cm. However, with the high accuracy and specificity of ultrasound in the differential diagnosis of echinococcosis cysts, there are certain disadvantages of the approach.Due to constant study and, accordingly, changes in knowledge about the course of the disease, methods for its diagnosis and treatment, there is no unified and stable ultrasound classification of liver echinococcosis. The paper analyzes the criteria that justify various classifications of echinococcus, substantiates forming trends. The standardi...
