Endometriosis is a functioning endometrial tissue outside the inner layer of the uterine wall. Liver endometriosis is one of the rarest forms of atypical endometriosis. In this article, we report a patient with this disease. A 59-year-old patient complained of heaviness and periodic pain in the right hypochondrium for more than a year. Previous contrast-enhanced CT revealed signs of cystic-solid hypovascular mass lesion in the right liver lobe. Histological examination revealed no reliable signs of tumor growth. According to control CT after 8 months, no significant changes were observed. Surgical treatment was indicated and atypical liver resection was performed. Histological examination revealed cystic endometrioid lesion. https://www.selleckchem.com/products/Erlotinib-Hydrochloride.html Liver endometrioma is a rare disease with unclear pathogenesis. Diagnosis is difficult due to uncharacteristic clinical manifestations and no specific markers. Liver endometriosis should be considered in differential diagnosis of liver lesion. Surgical treatment is preferable due to the risk of malignant transformation.Desmoid fibroma (DF) is a rare connective tissue tumor comprising about 0.03-0.13% of all neoplasms. DF has a low potential for malignant transformation, but it is characterized by aggressive course and unfavorable prognosis. The main contingent of patients consists of women of reproductive age. Despite the nearly two-century history of study, there are certain unsolved problems including endocrine problems associated with this disease. We report a 30-year-old female with DF and diabetes mellitus type 1. Total resection of the affected right rectus abdominis muscle was performed in a single block with aponeurotic sheath and peritoneum after normalization of carbohydrate metabolism. Muscular aponeurotic defect 27�10 cm was closed after separation of abdominal wall structures and implantation of polypropylene prosthesis. There are no X-ray and clinical signs of DF recurrence or postoperative hernia after 8 months.Venous thromboembolic complications (VTEC) including pulmonary embolism and acute thrombosis of deep and superficial veins of the lower extremities are often observed in postoperative period. Low-molecular-weight heparin (LMWH) is a common remedy for prevention and treatment of VTEC due to high efficiency, safety, easy use and dosage. According to the modern literature data, LMWH is characterized by different effectiveness in relation to VTEC and risk of bleeding in patients after surgical and traumatological procedures, as well as in ones with severe forms of chronic venous diseases. However, their antithrombin activity varies significantly depending on mean molecular weight. The authors analyze LMWH action mechanism, pharmacokinetic and pharmacodynamic features of LMWH, in particular parnaparin sodium. Efficacy, safety and tolerability of this remedy for various forms of VTEC (superficial and deep vein thrombosis, thrombophlebitis, complicated forms of chronic venous diseases), its advantages for prevention of VTEC after various surgical and orthopedic interventions are considered.Despite a significant decrease in postoperative mortality after pancreatic resections in recent years (5.2-15% after pancreatoduodenectomy and about 5% after distal pancreatectomy), incidence of postoperative complications remains high (30-50% and 22-50%, respectively). Postoperative pancreatic fistula is one of the most common and formidable complications. Currently, most authors use the classification proposed by the International Study Group for Pancreatic Fistula (biochemical failure, fistula type B and C). Prediction of the risk of postoperative fistula is still a complex and unresolved problem of modern surgical pancreatology. According to the literature, the main risk factors of postoperative pancreatic fistulae are obesity and high body mass index, concomitant cardiovascular diseases, no neoadjuvant chemo- and radiotherapy, soft pancreatic texture, narrow pancreatic duct, no fibrotic changes in parenchyma, adipose infiltration of the pancreas, advanced intraoperative blood loss, as well as center experience. Most often, magnetic resonance imaging, computed tomography, ultrasound elastography and various multivariate risk assessment systems are used to estimate the risk of pancreatic fistulae. However, a generally accepted technique does not exist. This manuscript is devoted to analysis of risk factors of postoperative pancreatic fistulae and diagnostic methods for assessment of this risk.It is known that liver is able to restore own dimensions and functional properties in response to various injuries. Despite extensive injuries, liver can preserve functional activity. Analysis of liver regeneration mechanisms allowed us to obtain significant results in the treatment of hepatitis, cirrhosis and liver failure. Liver regeneration processes substantiate the development of hepatocellular cancer following cirrhosis. Modern experimental and clinical data on liver regeneration, as well as current methods of stimulating this process are summarized in the manuscript. Despite significant advances in this issue, there are still many questions in scientific understanding of liver regeneration. To analyze the randomized controlled trials (RCTs) devoted to distal subtotal gastrectomy and gastrectomy with D2 lymphadenectomy in patients with distal gastric cancer. RCTs were searched in the electronic library, the Cochrane Community database, and PubMed database. A systematic review and meta-analysis were carried out in accordance with the recommendations of the Cochrane Community experts (Higgins et al. 2019). Mathematical calculations of a meta-analysis were made using RevMan 5.3 software package. Statistical criteria were calculated for relative risk (RR), hazard ratio (HR), 95% confidence interval (95% CI) and significance level ( ). Seven primary RCTs were selected. A total number of 1463 surgical interventions with D2 lymphadenectomy were observed (805 patients underwent distal subtotal gastrectomy, 658 - gastrectomy). Postoperative mortality is significantly higher (6.5% and 2.6%) after gastrectomy compared to subtotal distal gastrectomy (RR 2.2, 95% CI 1.34-3.64, I 0%, fixed effect model).
