[Characteristics of the periodic motor activity of the upper gastrointestinal tract in peptic ulcer and chronic pancreatitis].
A study was made of the periodical motor activity (PMA) of the antral part of the stomach (APS) and duodenum (D) using a manometric system of 4 continuously perfused catheters in 96 patients with peptic ulcer, 20 patients with ulcer of the body of the stomach, 26--with chronic pancreatitis, and in 16 healthy controls. PMA was normal only in 14 patients (10%). Different PMA disorders were revealed: increased frequency, decreased frequency, change of the duration of some phases, the occurrence of the activity site more distally of APS or even D, loss of coordination of antroduodenal motor activity, a decrease in APS motor activity, disorganization of the 2nd phase, etc. Possible mechanisms of PMA disorders were discussed.
