Intestinal Manometry in Man: A Historical and Clinical Perspective

Abstract

The historical background and current status of manometry of the small intestine are reviewed. The evolution of technology for the assessment of small intestinal motor activity in man is described and advances in physiology and pathophysiology highlighted. Technological advances over the past several decades have permitted the extensive study of intestinal motility in man and have led to both a greater understanding of intestinal motor physiology and an increased awareness of the breadth of intrinsic variability. Though motor patterns have been described in various disease states, the definition of the clinical utility of intestinal manometry must await further prospective studies, which should, in particular, compare manometry with other available and less invasive tests.

Antroduodenal Manometry: An Evaluation of an Emerging Methodology

“…Because of its relative accessibility, an troduodenal manometry has emerged as a po tential diagnostic tool. Whether performed using perfused catheter [7][8][9] or solid-state systems [10][11][12][13], antroduodenal manometry can provide information regarding fasting and postprandial motor patterns in the an trum and proximal small intestine. Indeed, manometry by detecting wall movement is the only technique available for the assess ment of motor patterns rather than move ment of luminal content.…”

“…Indeed, manometry by detecting wall movement is the only technique available for the assess ment of motor patterns rather than move ment of luminal content. Furthermore, ma nometry is capable of detecting alterations in these motor patterns among patients with non-ulcer dyspepsia, intestinal obstruction, intestinal pseudo-obstruction, postsurgical states and the short bowel syndrome [1,2,7,8,[14][15][16][17][18]. However, the clinical value of an troduodenal manometry has not been evalu ated in detail, and in particular, its ability to provide information over and above that pro vided by more standard diagnostic techniques has not been extensively assessed.…”

“…Some argue that pro longed recordings of fasting motility are nec essary to allow for intrinsic variations in mi grating motor complex activity [8]. Others support relatively short-duration fasting re cordings by arguing that migrating motor complex data are of limited clinical impor tance [7].…”

Evaluation of the Barostat for Recordings of Gastrointestinal Motility

“…Gastrointestinal motility recording by manometry reliably detects gut wall contractions in the esophagus, the pylorus, the small intestine or the anal canal [2, 3, 4, 5]. However, in regions of the gut with a wide luminal diameter like the stomach or the colon, manometry is hampered by a lack of contact of the catheter with the gut wall, thus not detecting all contractions.…”

Estudio espectral del ritmo eléctrico básico del intestino delgado para la monitorización no invasiva del marcapasos intestinal

“…Esta técnica consiste en introducir un balón en el interior del lumen intestinal, con el propósito de registrar las contracciones de la capa muscular circular [BAYLISS Y STARLING, 1899]. La ventaja de las técnicas manométricas es que permiten registros desde múltiples puntos a lo largo del intestino (Figura 2-6) y las contracciones pueden ser cuantificadas, obteniéndose con ello registros permanentes de la actividad motora durante varios complejos motores migratorios, durante el sueño y con diferentes tipos de alimentos [QUIGLEY E. M. 1994; QUIGLEY E. M. ET. AL, 1997;QUIGLEY EAMONN M. 2003].…”
