[Characteristics of the surgical treatment of total duodenal atresia].

The authors analysed the results of surgical management of total duodenal atresia in 12 newborns. In 10 of them the operation was successful. Duodenojejunoanastomosis on a short jejunal loop was formed through a window in the mesocolon in all patients.

[The treatment of bladder exstrophy].

The results of treatment of 41 children with vesical exstrophy were analysed. Four types of surgeries were performed: 1) transplantation of Lieutaud's triangle into the sigmoid (n = 19); 2) its transplantation into the semi-isolated part of the sigmoid (n = 7); 3) ureteral transplantation into the sigmoid (n = 3); 4) the formation of the urinary bladder and ureter from the adjacent tissues (n = 12). In the first group 2 children died, 6 patients had no clinical signs of chronic renal or ureteral inflammation for the period of 5-17 years, the remaining 11 patients had pyelonephritis.

[Unusual variants of proctoplasty in Hirschsprung disease].

The results of surgical treatment of 42 children with Hirschsprung's disease are analysed. The authors describe unusual 2-stage techniques of the perineal part of Duhamel's operation, consisting in primary downward transposition of the colon excess to the perineum and its subsequent (14 days later) removal with the formation of an intestinal intrapelvic wedge anastomosis. The method was applied in 23 children.
