Duplex-Doppler evaluation of intestinal peristalsis in patients with bowel obstruction

Abstract

Duplex-Doppler was used to visualize intestinal peristalsis in 30 patients with intestinal distension. The series included 12 patients with acute mechanical obstruction, 13 with long-standing mechanical obstruction, and five with paralytic ileus. The Duplex-Doppler recordings showed several patterns characterized by different degrees of intensity and frequency of the signals according to the type of obstruction, its duration, and the site of Doppler sampling relative to the obstructed segment. Duplex-Doppler evaluation provided both qualitative and quantitative data about intestinal peristalsis, allowing differentiation between mechanical and paralytic ileus. The visualization of intestinal segments having different degrees of peristaltic activity proved useful in localizing the site of mechanical obstruction.

Effect of romifidine on gastrointestinal motility, assessed by transrectal ultrasonography

“…Ultrasonography is a real-time dynamic imaging technique, and provides the opportunity to visualise the functional effects of intestinal contractions. In man, ultrasonography has been shown to provide qualitative and quantitative data about large and small intestinal peristalsis (Pistor 1989;Gimondo et al 1995;Gimondo and Mirk 1997). Studies in man have shown that ultrasonographic measurements of intestinal motility correlate well with scintigraphy measurements, have good interobserver variation, and are more accurate than electrical activity measurements (Irvine et al 1 9 9 3 ; P f a ffenbach et al 1995; Benini et al 1999).…”

Ultrasonography has therefore been used in man for some time to assess intestinal m o t i l i t y, both to identify regions of the intestine, and to document normal and abnormal peristalsis (Daggett 1974;Pistor 1989;Gimondo et al 1995). Ultrasonography is now widely used to evaluate normal intestinal function and different disease states, and to determine the effects of motility modifying drugs (Daggett 1974;Pistor 1989;Gimondo et al 1995;Huang et al 1 9 9 5 ;Dumitrascu et al 1998).…”

More recently, intestinal ultrasonography has been applied for veterinary use, where it has been used to evaluate both the number and type of peristaltic contractions, similar to that described in this study Wright et al 1998).…”

“…These reduced contractions have been previously described in disease states . M-Mode and Duplex Doppler ultrasonography can be used for division into further subtypes of m o t i l i t y, and for measurement of contraction amplitude (Gimondo et al 1995;Gimondo and Mirk 1997). In this initial evaluation of the technique, the analysis was performed simply as measurement of the number of contractions, and qualitative assessment of the type of contractions, as has been previously reported Gimondo et al 1995;Gimondo and Mirk 1997;Wright et al 1998).…”

Sonographische Ileusdiagnostik

“…Fur die Unterscheidung von mechanischem und paralytischem Ileus ist der Nachweis der bereits primar dilatierten Dunn-und Dickdarmschlingen sowie der prirnar fehlenden Peristaltik entscheidend [24]. Differentialdiagnostisch ist auch an die intestinale Pseudoobstruktion (Olgilvie Syndrom) mit ihren vielen unterschiedlichen Ursachen zu denken [25].…”
