Empfehlungen zur Anorektalen Manometrie im Erwachsenenalter[1]

Zusammenfassung

Die Gesellschaft für Neurogastroenterologie hat in Zusammenarbeit mit den Deutschen Gesellschaften für Verdauungs- und Stoffwechselkrankheiten (Kommission Proktologie), für Viszeralchirurgie (Arbeitsgruppe Colo-Proktologie) und für Koloproktologie Empfehlungen zur anorektalen Manometrie beim Erwachsenen erarbeitet. Die Empfehlungen umfassen die Abschnitte „Technische Grundlagen”, „Vor- und Nachbereitung”, „Durchführung und Auswertung”, „Reproduzierbarkeit” sowie „Indikationen”. Bei jeder anorektalen Manometrie sind als Mindestanforderung zu bestimmen: der Ruhe- und maximale Kneifdruck im Analkanal, das Vorhandensein respektive Fehlen des rektoanalen Inhibitionsreflexes, die sensorischen Schwellenwerte für Rektumdehnung (Perzeptions- und Stuhldrangschwelle) sowie eine Compliancemessung des Rektums bei einer Ballonfüllung mit 100 mL. In Abhängigkeit von spezifischen Fragestellungen oder laborspezifischen Protokollen kann zusätzlich die Analkanallänge, die Dauerkontraktionsleistung, die Schmerzschwelle bei Rektumdehnung bestimmt sowie ein Husten- oder Defäkationstest durchgeführt werden. Die Durchführung einer anorektalen Manometrie ist im Rahmen eines strukturierten Programms zur Abklärung der Stuhlinkontinenz und Obstipation indiziert. Weiter kann eine anorektale Manometrie im Einzelfall präoperativ, vor Biofeedback-Therapie sowie bei Patienten mit idiopathischem Schmerzsyndrom oder Reizdarm sinnvoll sein.

Abstract

This document contains the guidelines of the German Societies of Neurogastroenterology and Motility, Gastroenterology (committee for proctology), Abdominal Surgery (coloproctology working group), and Coloproctology for anorectal manometry in adults. Recommendations are given about technical notes, study preparation (equipment; patient), technique for performing manometry and data analysis, reproducibility, and indications. Minimum standards for anorectal manometry are measurement of resting and squeeze pressure, testing of rectoanal inhibitory reflex, determination of rectal sensation (first perception and urge), and calculation of rectal compliance. Anorectal manometry is indicated in patients with fecal incontinence and constipation in the context of a structured programme.
