Authors: Ryazantsev A. A. , Yudin A. L. , Yumatova E. A. 
Published: December 2019

Aim. To systematize modern literature data on medical imaging of textile iatrogenic foreign bodies.Materials and methods. We analyzed the articles about the identification of textile iatrogenic foreign bodies, published until 2019.Discussion. Foreign body detection should be included in the differential diagnostic algorithm for patients who have a history of surgical interventions and unexplained symptoms. In all cases of suspected iatrogenic foreign body, it is desirable to use at least two available techiques of medical imaging: ultrasound, X-ray, MDCT, MRI.Conclusions. Left foreign body entails medical and legal consequences that adversely affect both the reputation of the surgeon and the reputation of the medical institution, as they are considered a classic example of iatrogenic damage and indicate a violation of the quality standards of medical care. The article presents data on the features of medical imaging of textile iatrogenic foreign bodies left in the patient’s body as a result of planned and emergency surgical interventions, and determining the optimal tactics for examination and treatment of this category of patients.

Objective: efficacy evaluation of the CEUS LI RADS v2017® system for differential diagnosis of liver tumors in patients with and without cirrhosis.Materials and methods. Retrospective analysis of diagnostic results of the 165 patients with liver tumors (177 nodules) was done. All patients underwent CEUS with results interpretation in accordance to the CEUS LIRADSv2017 ® criteria. Patients were divided into 2 groups based on clinical and morphological data. Group 1 included 62 patients with cirrhosis and/or CVH. Group 2 included 110 patients without risk factors for HCC.Results. Diagnostic efficiency of CEUS LI RADS v2017® for HCC identification was: group 1 – Se – 100%, Sp – 88%, Ac – 95.5%; group 2 – Se – 100%, Sp – 68.8%, Ac – 72.7%; general group Se – 100%, Sp – 72.2%, Ac – 81.4%. In the 2nd group, 21 out of 22 neoplasms, confirmed morphologically as FNH, we classified as LR 4. By applying benign character and specific contrasting patterns of FNG, they were transferred from LR 4 to LR 3. This allowed to increase sensitivity and specificity of differential diagnosis in group 2 (Se – 100%, Sp – 90.6%, Ac – 91.8%) and in general group (Se – 100%, Sp – 90.1%, Ac – 93.2%). Diagnostic efficiency of the criteria for non hepatocellular malignant neoplasms (LR M) was: group 1 – Se – 77.8%, Sp – 100%, Ac – 97%; group 2 – Se – 90%, Sp – 96.7%, Ac – 93.6%; general group- Se – 88.1%, Sp – 98.3%, Ac – 94.9%.Conclusion. Our study confirmed high accuracy of the CEUS LI RADS v2017® system in the differential diagnosis of focal liver tumors. Modification of the system (in particular, transfer of typical FNG forms from the LR 4 category) will make it possible to increase the accuracy of diagnostics by 20%. It will allow to use the LI RADS v2017® system for interpretation CEUS not only among patients with liver cirrhosis, but also in a general group without risk factors of GCC.

Authors: Gromov A. I. , Gorinov A. V. , Galljamov E. A. 
Published: December 2019

Objective. We aimed to research abilities of magnetic resonance imaging (MRI) in determination of the contents of the cysts, including fat suspension.Methods. MRI study of patient with mesenteric chylous lymphangioma and experimental MRI study of a fantom containing fat suspension were done.Results. MRI study of patient revealed non organic abdominal cystic lesion with significant decrease of MR-signal intensity on out-of-phase GRE images. MRI imaging of fantom with fat suspension also showed low MR-signal intensity on out-of-phase images.Conclusion. Opposed-phase GRE sequences can be used not only for determining high content intracellular fat in tissues, but for determining lipids in fat containing suspensions as well. Homogeneous decrease of signal intensity on out-of-phase images in extraorgan abdominal cystic lesion indicate its chylous character. That is why cystic lesion, presented in this article, most likely to be chylous cyst or mesenteric lymphangioma.

Published: December 2019

The OBJECTIVE was to evaluate the results of endoscopic treatment of cicatrical tracheal stenoses.MATERIAL AND METHODS. During the period from 1995 to 2018, 145 patients with cicatrical tracheal stenoses (men – 102, women – 43) aged 15 to 83 years were treated in the clinic. Stenosis was post tracheostomy in 96 patients, postintubation in 39 patients, after circular tracheal resection in 6 patients, after tracheolaryngoplasty in 3 patients, after radiation therapy for primary tracheal cancer in 1 patient. Endoscopic treatment was performed in 136 patients.RESULTS. In the tracheal dilation, only 42 (30,88 %) patients managed to achieve stabilization of the lumen of the trachea. Stenting of the narrowed part of the trachea with stent type Dumon was in 62 (45,58 %) patients due to restenosis. Formation of the lumen sufficient for breathing was possible in 40 (70,2 %) patients. All the complications that occurred during the stent in the trachea were diagnosed and eliminated.CONCLUSION. Endoscopic methods of treatment of patients with cicatrical tracheal stenoses were highly effective allowing to restore and maintain airway patency, both temporarily (for the purpose of preoperative preparation) and constantly.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

Published: December 2019

The analysis of literature on the possibility of performing anatomical pulmonary resections in patients with concomitant COPD was performed. According to most researchers, FEV1 and DL (CO) more than 80 % indicated a high probability of an uncomplicated postoperative period after any anatomical resection of the lung. If the specified parameters were less than 80 %, additional studies were required: functional tests (6-minute walk test, staircase test), stress testing, calculation of predicted postoperative values of respiratory function, and, if necessary, lung scintigraphy could be performed to study regional respiratory function. The decision about the possibility and need for surgical treatment should have been made individually at the threshold values of these parameters. At the same time, there is currently no system for assessing the risk of postoperative complications for a particular patient, based on all the information about it, which represents the potential for further research.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

INTRODUCTION. MGB is considered to be the best alternative to Roux-en-Y gastric bypass (RYGB) due to the shorter operation time and fewer possible complications. The OBJECTIVE of this study was to determine biliary reflux in patients undergoing MGB with a hand-sewn gastroenteroanastomosis, and MGB with a stapler gastroenteroanastomosis.MATERIAL AND METHODS. This study included the analysis of results of treatment of 122 patients with morbid obesity and metabolic syndrome who had undergone laparoscopic MGB. Patients were divided into two clinical groups depending on the method of applying gastroenteroanastomosis. Clinical and endoscopic assessment was used to determine bile reflux; biliary reflux index (BRI) was used. In the postoperative period, the possibility of developing biliary reflux using fibrogastroscopy with biopsy of the gastric mucosa, microscopy of biopsy materials was evaluated. Microscopy of biopsy specimens was performed by a pathologist who evaluated each sample of gastric tissue in accordance with the system for determining the biliary reflux index (BRI).RESULTS. During fibrogastroscopy, biliary reflux was diagnosed in 9 (15.5 %) cases in the study group and 16 (26.6 %) cases in the control group. In the study group of patients, biliary reflux index (BRI) > 14 was determined in 3 patients (5.153 %). In the control group of patients, BRI> 14 was in 7 cases (10.94 %). The difference was significant (p<0.05).CONCLUSION. Determination of BRI index in patients undergoing MGB could be used as a screening method for diagnosing the biliary reflux in order to prevent and develop the tactic for further management of patients from a risk group of complications associated with the toxic effects of an aggressive bile refluxate.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

The OBJECTIVE was to study the changes of bioelectric activity of muscles in patients with local cold injury of the feet.MATERIAL AND METHODS. Non-invasive method of cutaneous electroneuromyography was used to evaluate the bioelectrical activity of muscles. The study was conducted in 52 patients with local cold injury of III–IV degree of the lower extremities of the late reactive period and the period of granulation and epithelialization. M-response amplitude, residual latency and propagation velocity of the excitation were estimated.RESULTS. In patients with local cold injury, there was a decrease in the bioelectric activity of the limb muscles proximal to the affected area. M-response amplitude and the propagation velocity of the excitation decreased in the patients in the late reactive period, while the residual latency increased. In patients with frostbite limbs during granulation and epithelialization, there was a tendency to restore the level of bioelectrical activity of muscles relative to the late reactive period.CONCLUSION. The basis of the adverse effects of local cold injury was “chronic” endothelial dysfunction and local neuropathy.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

The OBJECTIVE of this work was to study the possibility of preoperative color 3D-modeling and intraoperative navigation through the use of the system «Avtoplan» in the surgical treatment of patients with pathology of the liver.MATERIAL AND METHODS. System «Avtoplan» was used in 32 patients with different surgical diseases of the liver: hemangioma, hydatid cyst, alveococcosis and metastatic colorectal cancer to assess the feasibility of the operation – resection of the liver of a particular volume.RESULTS. The performed 3D-modeling of the liver in the preoperative stage were used in 3 cases (10.3%) of 32 to abandon the planned surgical treatment in favor of conservative therapy due to local spread of the pathological process (in 2 cases – metastatic bilobate and in 1 case – alveococcosis organ damage). Of the 29 operated patients, in 6 (20.7%) at the stage of preoperative modeling, the planned volume of liver resection was changed: in 4 patients, in the direction of its increase in connection with the identified topographic and anatomic location of tumors, and in 2 patients, in the direction of its reduction due to the peculiarities of the blood supply to the zone of surgical interest.CONCLUSION. Preoperative 3D-modeling allowed the surgeon to better prepare for surgical intervention according to individual anatomical characteristics of the patient and to choose the optimal extent of surgery. Knowledge of 3D topography of liver lesions allowed reducing intraoperative blood loss and the likelihood of damage to intrahepatic structures (vessels, bile ducts). Postoperative 3D modeling allowed to assess the adequacy of the volume of surgery performed and could serve as an objective criterion in assessing the quality of medical care.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

INTRODUCTION. Diffuse peritonitis remains a topical problem of modern medicine and is still associated with high mortality. The OBJECTIVE of this work was to develop an objective and easy-to-perform method for determining the indications for programmed relaparotomy in patients with diffuse peritonitis on the basis of determining the aggressiveness of its course.MATERIAL AND METHODS. The work was based on the results of treatment of 100 patients with diffuse peritonitis. Depending on the pH of the exudate of the peritoneal cavity, the patients were divided into 2 groups. The first group consisted of patients with pH value of peritoneal exudate more than 6.2 (75 patients), and the second group consisted of patients with pH value of peritoneal exudate 6.2 and less (25 patients).RESULTS. As a result of the treatment in group I, the mortality rate was 12.0 %. In group II, the mortality rate was 56.0 %. The difference was statistically significant (p<0.001). In group I, 4 patients underwent relaparotomy (5.3 %), and in group II, 17 patients underwent relaparotomy (68.0 %). The difference was statistically significant (p<0.001).CONCLUSION. We concluded that at pH value of exudate 6.2 or less and the absence of obvious clinical improvement, the patient had been showed to performance the programmed remedial relaparotomy no later than 48 hours from the first operation.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

Relevance. There is a need to evaluate doses retrospectively in Chernobyl nuclear power plant accident recovery workers without established external doses.Intention: To assess the ability of cytogenetic analysis to estimate external radiation doses retrospectively in Chernobyl nuclear power plant accident recovery workers exposed to low-dose radiation in the remote period.Methodology. Cytogenetic biological indication and biological dosimetry were performed in Chernobyl nuclear power plant accident recovery workers 27–30 years after their participation in recovery works. Stable and unstable chromosome aberrations were assessed in peripheral blood lymphocytes.Results and Discussion. The analysis of unstable chromosome aberrations showed that 45.1 % of Chernobyl nuclear power plant accident recovery workers had radiation markers more frequently than in the comparison group. Biological doses were retrospectively evaluated in 18 % of Chernobyl nuclear power plant accident recovery workers and ranged within 14–48 cGy. Specific anamnestic factors should be assessed while evaluating doses retrospectively.Conclusion. Analysis of stable chromosome aberrations allows retrospective dosimetry after low-dose exp sure if external dose is unavailable. Based on this, adverse health effects of low-dose exposure can be assessed and reimbursed in Chernobyl nuclear power plant accident recovery workers.
