[Diagnostic value of stepwise manometry in chronic duodenal obstruction, associated with duodenal ulcer].

Stepwise manometry was performed in 449 patients with chronic duodenal ileus (CDI) combined with duodenal ulcer. Manometric values in CDI appeared diagnostically significant. These were indicative of the disease in 82% of cases. There are 3 types and 8 variants of duodenomanometric curves in respect of the disease stage and form. The curves may be useful in making decision on surgical treatment and assessment of its efficacy.
