Do preoperative endoscopic interventions predict symptom recurrence or reintervention after peroral endoscopic myotomy?
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStudies assessing outcomes of patients undergoing peroral endoscopic myotomy (POEM) after botulinum injection or dilation have had various results with respect to failure, although this has not been differentiated between lack of clinical response and recurrence. We hypothesize that patients with previous endoscopic intervention(s) are more likely to recur than treatment-naïve patients.
methodsThis is a retrospective cohort study of patients that underwent POEM for achalasia at a single tertiary care center between 2011 and 2022. Patients were excluded if they had previous myotomy (POEM or Heller). The remaining patients were stratified into treatment-naïve patients (TN), those with previous botulinum injection (BTX), those with previous dilatation (BD), and those with both previous endoscopic interventions (BOTH). Primary outcome was recurrence indicated by clinical symptoms or need for repeat endoscopic intervention or surgery after originally having clinical resolution (Eckardt ≤ 3). Multivariate logistic regression using preoperative and intraoperative factors was completed to assess odds of recurrence.
resultsA total of 164 patients were included in the analysis, 90 TN, 34 BD, 28 BTX, and 12 BOTH. There were no other significant differences in demographics or in preoperative Eckardt score (p = 0.53). There was no difference in the proportion of patients that had postoperative manometry (p = 0.74), symptom recurrence (p = 0.59), surgical intervention (p = 0.16). BTX (14.3%) and BOTH (16.7%) patients had a higher rate of repeat endoscopic intervention than BD and TN patients (5.9% and 1.1%). In the logistic regression analysis, there was no association among the BTX, BD, or BOTH groups compared to the TN group. No odds ratios achieved statistical significance.
conclusionsThere were no increased likelihood of recurrence with botulinum injection or dilatation prior to POEM, implying that they are similarly good candidates compared to treatment-naïve patients.
