Manometric Evaluation of Gastrointestinal Motility in a Case of Megacystis-Microcolon-Intestinal Hypoperistalsis Syndrome (MMIHS)

We report on a manometric study of the esophagus, stomach, duodenum, jejunum and anorectum in a case of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS). An esophageal examination showed normal esophageal contractions and a positive rectoanal reflex was obtained in an anorectal manometry. However, the continuous fasting manometric recording of the antrum, duodenum and jejunum lasting a total of 12 hours revealed a severe motility disturbance of the gastrointestinal tract. During the examination a band of low amplitude contractions was observed in the antrum only once and it was followed by small rhythmic contractions of the duodenum, but none of propagated or spontaneous contractions were seen in the jejunum.
