Development and validation of microcomputer analysis of gastric and small‐bowel manometry

Abstract

A novel microcomputer method for analysis of gastric and small‐bowel motility was developed for recognition and measurement of inter‐digestive migrating motor complexes (MMC) and associated features as well as fed‐state contraction characteristics. Facilities for removal of signal artefacts were also provided. This microcomputer method was validated against observer findings in 24‐h ambulatory gastric and small‐bowel motility studies of six volunteers. No significant differences were found between microcomputer and observer motility analysis relating to MMC number, MMC migration velocity, fed‐state contraction characteristics or artefact recognition. This method provides an accurate automated method for measurement of gastric and small‐bowel motor physiology. Copyright © 1992, Wiley Blackwell. All rights reserved
