Motility Patterns Following Esophageal Pharmacologic Provocation With Amyl Nitrite or Cholecystokinin During High-Resolution Manometry Distinguish Idiopathic vs Opioid-Induced Type 3 Achalasia.
Article in Clinical gastroenterology and hepatology : the official clinical practice journal of the American Gastroenterological Association, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND &
aimsIn some patients, the type 3 achalasia (A3) motor pattern may be an effect of chronic use of high-dose opioids. No motor findings have been identified to differentiate opioid-induced A3 (OA3) from idiopathic A3 (IA3). We investigated whether OA3 could be distinguished from IA3 on the basis of differences in esophageal motor responses to amyl nitrite, cholecystokinin, or atropine.
methodsWe performed a retrospective study of patients who received pharmacologic provocation during esophageal high-resolution manometry from 2007 through 2017 at a tertiary referral center. We identified 26 patients with IA3 (9 women; mean age, 68 ± 13 years) and 24 patients with OA3 (15 women; mean age, 59 ± 10 years). We compared pressure topography metrics during deglutition and after administration of amyl nitrite, cholecystokinin, or atropine between patients with OA3 vs IA3.
resultsAmyl nitrite induced a similar relaxation response in both groups, but the rebound contraction of the lower esophageal sphincter during amyl nitrite recovery, and the paradoxical esophageal contraction during the first phase of cholecystokinin response, were both significantly attenuated in patients with OA3. The second phase of cholecystokinin response in patients with OA3 was 100% relaxation, when present, in contrast to only 26% of patients with IA3. There was no significant difference between groups in inhibition of lower esophageal sphincter tone or esophageal body contractility by cholinergic receptor blockade.
conclusionsNearly half of patients with an A3 pattern of dysmotility are chronic, daily users of opioids with manometry patterns indistinguishable from those of patients with IA3. Patients with OA3 differ from patients with IA3 in responses to amyl nitrite and cholecystokinin. These findings might be used to identify patients with dysmotility resulting from opioid use.
