[Indications for surgery and methods of surgical correction of infundibuliform abnormality of the chest in children].

Based on the survey of 104 patients, a method has been developed for early diagnosis of progression of infundibuliform chest deformity (ICD), which defines indications for thoracoplasty in children over 2 years. A differential approach has been applied to the stabilization of the sternocostal complex, taking into account various ICD types. Experience in surgical management of 247 patients with simple and complex ICD types has been generalized. A procedure has been improved to stabilize the sternocostal complex with a metallic plate in critical ICD types. The sparing thoracoplasty variants have been developed for simple ICD types and Degree I progressive ICD ones, stabilizing the sternocostal complex with a niticolic brace and a CPK-22 apparatus in the modified resistant case.

[The inflammatory-reparative processes in the implantation of the ureter into the bladder by using the mechanical forces of permanent magnets].

An anastomosis between the ureter and the bladder using ring magnets was first made in our and foreign countries, Magnetic-compressive systems, based on alloy of samarium and cobalt (CS-37), were developed, taking into account their practical use in pediatric surgery. Morphological studies showed that the magnetic compressive procedure for connecting the ureter with the bladder has some advantages.

[Effect of subtotal resection of costal cartilage on the basic chest dimensions in children with funnel chest deformity].

The paper summarizes the results of anthropometric and computed tomographic studies of the external and internal chest dimensions in 86 patients with Degree II-III infundibuliform chest deformity. Full resection of deformed cartilages of the third to seventh ribs has been examined for its impact. The children with infundibuliform chest deformity have been found to have an impressed anteroposterior dimension of the bilateral chest. The transversal and anteroposterior dimensions of the chest remain unchanged after removal of cartilages. The chest enlarges only sagittaly. One- and three-year follow-ups have indicated that full removal of the deformed cartilage has no impact on the growth of the chest.

[Differentiated approach to the method of sternum stabilization in surgical treatment of funnel chest in children].

Experience in surgical treatment of 186 patients with funnel chest deformity (FCD) is generalized. With consideration for the great variety of the forms of deformity of the plastron, simple and complicated forms of FCD are distinguished. The simple forms include isolated, symmetrical, low (beginning from the level of the fourth rib) II-III degree deformities, the complicated forms include wide, II-III degree deformities beginning from the level of the second rib, and flat asymmetrical deformities. The use of a metal plate as a stabilizer in complicated forms of FCD is suggested. The optimal method of treatment in simple forms of the deformity is thoracoplasty with fixation of the sternum in the corrected position by means of a nitinol clip.

[The treatment of intestinal fistulae in children by applying a by-pass anastomosis using magnetic devices].

A new method is suggested for the exclusion of intestinal fistulas by the formation of by-pass anastomoses by means of a permanent magnet. The variants of the techniques of magnet by-pass anastomoses are discussed. The results of treatment of 46 children with external intestinal fistulas are shown. With the formation of a by-pass compression anastomosis the mortality rate among children with intestinal fistulas reduced from 31 to 13%.

[Treatment of short urethral strictures in children using magnets].

In 20-35 per cent of short (up to 05 cm) urethral stenosis or cicatricial obliterations of urethra it was found advisable to start the treatment with nonoperative technique. Before 1982 bouginage or tunneling of urethra were commonly used. In 5 out of 6 children the strictures relapsed. Since 1983 when permanent magnets were employed, in 4 out of 5 patients normal urination recovered. 1 child was exposed to preventive 5-months bouginage to ensure constant patency of urethra. Long-term results in all the children satisfied the investigators. But out of 3 magnet-treated children with longer strictures (more than 1 cm) the disease relapsed in 2. It was concluded that in patients with longer stenosis the method was a failure, but in those with short ones the technique was more effective than routine methods. Besides, technical availability, safety and shorter terms of the treatment could also be regarded as the benefits of the aforementioned therapy.
