Abstract

BACKGROUND: The manometric diagnosis of severe intestinal dysmotility is performed at most institutions using catheters with 2-8 sensors 5-10 cm apart. The recent application of high-resolution manometry catheters with closely spaced sensors to other gut segments has been highly successful. The objective of the present study was to determine the feasibility of a jejunal high-resolution manometry method and to carry out a descriptive analysis of normal jejunal motor function. METHODS: A 36-channel high-resolution water-perfused manometry catheter (MMS-Laborie, Enschede, The Netherlands) was orally placed in the jejunum of 18 healthy subjects (10 men, eight women; 21-38 age range). Intestinal motility was recorded during 5 h, 3 during fasting, and 2 after a 450 kcal solid-liquid meal. Analysis of motility patterns was supported by computerized tools. KEY RESULTS: All healthy subjects except one showed at least one complete migrating motor complex during the 3 h fasting period. Phase III activity lasted 5 ± 1 min and migrated aborally at a velocity of 7 ± 3 cm/min. High-resolution spatial analysis showed that during phase III each individual contraction propagated rapidly (75 ± 37 cm/min) over a 32 ± 10 cm segment of the jejunum. During phase II, most contractile activity corresponded to propagated contractile events which increased in frequency from early to late phase II (0.5 ± 0.9 vs 2.5 ± 1.3 events/10 min, respectively; p < 0.001). After meal ingestion, non-propagated activity increased, whereas propagated events were less frequent than during late phase II. CONCLUSIONS & INFERENCES: Jejunal motility analysis with high-resolution manometry identifies propagated contractile patterns which are not apparent with conventional manometric catheters.

  • Advanced techniques, including antroduodenal‐jejunal manometry, wireless motility capsule, gastric ultrasound, and high‐resolution electrogastrography (EGG), may provide additional pathophysiological insight, particularly in complex or mixed‐pattern cases.

    “Advanced techniques, including antroduodenal‑jejunal manometry [71–75], wireless motility capsule [76–79], gastric ultrasound [80–82], and high‑resolution electrogastrography (EGG) [83–87] may provide additional pathophysiological insight, particularly in complex or mixed‑pattern cases.”

    The Introduction and Discussion describe high-resolution jejunal manometry as useful for analysing propagation patterns and potentially valuable for diagnosis. The Discussion says its clinical relevance in patients with suspected dysmotility remains to be established; the study does not specifically address complex or mixed-pattern cases. This citation is attached to manometry, not to the other techniques listed in the sentence. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
