[Duodenal function in some diseases of upper abdominal organs].

Eighty-five children with surgical parasurgical and pediatric abnormalities of upper abdominal organs were studied. In addition to the routine procedures, the authors used the following: endoscopic stepwise manometry, electromyography, polarography, pH-metry. In some chronic pediatric diseases, manometric, polarographic, electromyographic changes were found to correlate with the similar ones in surgical abnormalities. The findings provide strong evidence for the necessity of more comprehensive examinations of the duodenum in children with surgical and pediatric upper abdominal abnormalities in order to earlier detect the indications for surgical treatment, to assess the outcomes of treatment and to predict the course of rehabilitation.
