[Results of surgical treatment of bronchiectasis in children].

Among the causes of complications occurring in the early postoperative period in children is purulent endobronchitis which in most cases cannot be arrested in the preoperative period by the traditional methods of bronchoscopic cleansing. Endobronchial application of a helium--neon laser beam in a complex with the traditional methods in the preoperative period allows endobronchitis to be arrested and the postoperative complications to be reduced to 3% of cases.

[Anoplasty for anorectal anomalies in children].

The work analyses the causes of insufficient air-tightness of the anal canal in the postoperative period (in children operated on for anorectal developmental anomalies), which leads to anal incontinence. The authors suggest a method for anoplasty based on: (1) performance of sphincteroplasty with consideration for the function of three muscles forming the external sphincter of the anal canal; (2) formation from the musculo-serous coat of the intestine subjected to the pull-through procedure a soft elastic pad lining the canal on the inside; (3) creating conditions for adherence of the mucous coat of the intestine to the walls of the neoanal canal. Manometric, CT, and ultrasonic special methods of examination showed that with the use of the suggested method the obturative pressure in the neoanal canal increases, "prolapse" of the mucosa of the operated on intestine is prevented, the accumulative and evacuative functions of the rectum are improved. The causes and errors which led to poor results (2 cases) are analysed. In the remaining 42 cases the results were good and satisfactory.

[Congenital stenosis of the anus and rectum (Problems of nosology and pathogenesis)].

The work deals with the differential analysis of two forms of congenital rectal stenosis--"membranous" which is consequent upon incomplete obliteration of the anal membrane and "tubular" with involvement of the rectum along its length. It is pointed out that in most cases tubular rectal stenosis is a component of the complex of anomalies of the caudal region described for the first time by G. Currarino (1981) and called the ASP-triad. From analysis of 12 cases of the ASP syndrome a new scheme of the pathogenesis of the complex of anomalies constituting the syndrome is suggested. The authors identified a component of the syndrome which was not described earlier, namely, specific dysplasia of the pelvic floor and the external sphincter muscles of the anus, which provided the basis for naming the complex the PFASP syndrome (PF--Pelvic Floor Dysplasia). Problems of surgical correction of the PFASP complex of anomalies are discussed. A pathogenetically substantiated analysis of postoperative complications is made.

[Functional state of the recto-anal segment in normal conditions and in various diseases in children].

The functional state of the anorectal segment was studied in normality and in chronic constipation and incontinence of feces of different genesis. Continuous profilometry of rectal pressure, registration of motility of the rectum and sphincters, EMG and reflexometry were performed. A complex assessment of the findings helps to reveal the pathogenetic essence of the disease, to make differential diagnosis between organic and functional disorders, to find the rational tactics of treatment.

[Current trends and problems in surgery for Hirschsprung's disease in children].

The authors discuss the results of 211 operations for Hirschsprung's disease with special reference to the optimal terms for surgery, questions of medical policy and remote results. The remote results were studied in 102 patients. Excellent results were obtained in 63% of cases, good--in 28% and in 9% the results were satisfactory. The authors make special accent on residual functional disorders and necessary rehabilitation measures till full recovery of the patient.
