Complications of endoscopic esophageal stent implantation

Endoscopic esophageal stent implantation is an effective method for dysphagia management in malignant esophageal stricture. However, this technology is associated with the risk of many complications, including those fatal to life. These include bleeding, restenosis, stent fragmentation and destruction, stent migration, pneumomediastinum, the formation of esophageal fistulas, perforations, clogging of the stent with food, retrosternal pain, gastroesophageal reflux changes, airway compression, aspiration pneumonia, and fever. The overall complication rate is 3640%. Mortality rates associated with stenting is between 3.9 and 27.2%. Nevertheless, today there are ways to minimize the incidence of complications due to the constant progress of endoscopic technologies and improvements in the design of modern stents. In addition, most endoscopic interventions can manage the vast majority of complications effectively after stent implantation subject to their early detection. Optimal selection of an esophageal stent and careful selection of patients with a low risk of complications associated with stent implantation are important problems in the prevention of complications to achieve high efficiency of stenting. Evaluation of risk factors for possible complications, the design of stents and their characteristics, as well as using modern methods of effective management of possible complications improves the quality and duration of life in incurable patients with esophageal cancer. The review reflects all possible complications of stenting in esophageal and gastroesophageal junction, factors affecting the occurrence of complications, as well as modern and effective methods of their correction and prevention.

Background: Female sterilization by tubal ligation accounts for 36% of all methods of family planning used in our country. Almost half of tubal ligations are done in women younger than 25 years. These women want reversal of tubectomy subsequently, in circumstances like death of children, remarriage. This study aims to evaluate various factors affecting the outcome of pregnancies following microsurgical tubal recanalisation.Methods: It is a prospective observational study carried out at Govt Kilpauk Medical College for a total number of 50 patients who have undergone tubal recanalisation during 2011 and 2012. They were followed up till December 2016.Results: 84% of women (n-42) opted for recanalisation were in young reproductive age (<30 years) group. Conception rate was higher in younger age group (52.9% in 21-25 years). Death of children (n-37, 74%) and remarriage (n-12, 24%) were the common indications for tubal recanalisation. Outcome is better if reversal surgery is done within 4 years after sterilization (69.6%, n-16 out of 23) than after 4 years (30.4%, n-7out of 23). Conception rate (55.3%, n-21) was higher and statistically significant in subjects with final length of tube more than 4 cms (P value -0.0193). Conception rate was higher within 1 year of recanalisation (n-13, 26%), followed by 16% (n-8) in 2nd year and statistically significant (p- 0.00001). Overall pregnancy rate in our study was 46% (n-23). Out of the 23 women who conceived, 14 (61%) resulted in live birth, 3 (13%) abortions and the remaining 6(26%) had ectopic pregnancies.Conclusions: Proper selection of patients and meticulous tuboplasty technique can yield successful pregnancy outcome comparable to ART.

Introduction. As part of the work on the study of methods of protection of slopes from erosion using bulk geogrid was found the problem of leaching the filler material from the cells under the influence of water flow. The relevance of the work is due to the widespread use of bulk geogrid structures in the construction, which are the subject of the study. The aim is to develop recommendations for the choice of the material of the filler volume geogrid. The objectives of the study are to study the factors affecting the efficiency of retention of the filler. The practical significance lies in the fact that scientifically-based recommendations on the choice of the filler material of bulk geogrids have been developed. For many years, the improvement of structures and the development of new solutions for the protection of structures from water erosion were carried out by various specialists in the field of hydraulic research of objects of hydraulic and transport construction, including: I. Levi, A. Guryev, N.In. Khanov, Yu.M. Kosichenko, K.D. Kozlov, W. Müller, O. Kief, Y. Schary and others. Materials and methods. The method of research was to conduct a complex of theoretical and experimental work in the laboratory. Practical methods taking into account the specifics of the study include the implementation of experiments. Theoretical methods are associated with the planning of experiments, traditional statistical methods of information processing, analytical calculations. Results. On the basis of the performed experiments high efficiency of retention of large aggregate (crushed stone) and small (sand) volume geogrid under the influence of water flow was revealed. Based on the calculations of the critical velocities of particle drift from the slope and stability calculations of the geogrid on the slope, the limit values of the slopes with bulk geogrids are obtained. Conclusions. These tests have led to the conclusion that one of the key reasons for the collapse of the slopes is the wrong choice of filler material. In addition, the developed technique of selection of parameters of volumetric geogrid as to not flood prone and flood prone slopes.

Introduction: The average incidence of perioperative stroke during major non-cardiac surgery is less than 1%, suggesting that it is rarely a major problem for the vast majority of patients. Methods: In our paper we present a 46-year-old patient undergoing acute right hemicolectomy who developed right-sided hemiparesis in the perioperative setting. Immediate CTAg examination showed an ischemic stroke in the left hemisphere as a result of left internal carotid thrombosis. A surgical procedure to recanalize the left carotid artery was performed 14 hours from the onset of neurological symptomatology and the neurological deficit gradually recovered fully. Conclusion: Our case report supports studies showing that a thorough diagnostic assessment allows the selection of patients who may benefit from urgent revascularization of acute internal carotid occlusion during the phase of acute brain ischemia.
