Selection of the method of operation on the stomach in the complex treatment of esophageal and gastric burns

The results of treatment of 317 patients with concurrent burn of the esophagus and stomach are generalized. Various restorative operations were carried out in 214 of them. The pyloroplasty-type plasty with local tissues was performed in short strictures of the pylorus, cardioesophageal junction, duodenum, and the initial portion of the small intestine. Resection of the stomach after Billroth I was conducted in cicatricial affection of the distal part of the stomach. The Billroth II operation or gastroenterostomy is indicated in subtotal burn and combined cicatricial stenosis of the stomach and duodenum. Enterostomy with subsequent restorative operation is indicated in total burn of the stomach. Preoperative management with consideration for the operative risk, elaboration of a rational therapeutic tactics and improvement of operative techniques with the use of laser and microsurgical techniques facilitated a decrease in the number of complications and in the mortality rate.     

Electromyographic examination of patients with cerebral palsy

The article is devoted to the analysis of electromyographic investigations in 268 patients with infantile cerebral paralysis before and after orthopaedic and surgical treatment. It has been established that the value of electrogenesis of the affected muscles mostly correlates with the degree of the patients' motor activity. However, the development of fixed contractures suppresses the possibility of manifestation of electrical activity of the muscles, and the orthopaedic and surgical intervention climinates these obstacles, creating thus the conditions for muscle activity. Besides, it has been demonstrated that in general any kind of surgical intervention leads to reduction of electrogenesis in the muscles, and this trend is most expressed after the intervention on tendons and muscles, and least after the correction of the contractures with special devices. The dynamics of restoration of electrogenesis, reciprocity and other electromyographic values after the surgical treatment has been studied.
