1 · What the graph read from it

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.

2 · The registry

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

introductionWith the advent of the laparoscopic era in the 1990s, laparoscopic Heller myotomy replaced pneumatic dilation as the first-line treatment for achalasia. An advantage of this approach was the addition of a fundoplication to reduce gastroesophageal reflux disease (GERD). More recently, Peroral Endoscopic Myotomy has competed for first-line therapy, but the postoperative GERD may be a weakness. This study leverages our experience to characterize GERD following LHM with Toupet fundoplication (LHM+T ) so that other treatments can be appropriately compared.

methodsA single-institution retrospective review of adult patients with achalasia who underwent LHM+T from January 2012 to April 2022 was performed. We obtained routine 6-month postoperative pH studies and patient symptom questionnaires. Differences in questionnaires and reflux symptoms in relation to pH study were explored via Kruskal-Wallis test or chi-square tests.

resultsOf 170 patients who underwent LHM+T , 51 (30%) had postoperative pH testing and clinical symptoms evaluation. Eleven (22%) had an abnormal pH study; however, upon manual review, 5 of these (45.5%) demonstrated low-frequency, long-duration reflux events, suggesting poor esophageal clearance of gastric refluxate and 6/11 (54.5%) had typical reflux episodes. Of the cohort, 7 (15.6%) patients reported GERD symptoms. The median [IQR] severity was 1/10 [0, 3] and median [IQR] frequency was 0.5/4 [0, 1]. Patients with abnormal pH reported more GERD symptoms than patients with a normal pH study (3/6, 50% vs 5/39, 12.8%, p = 0.033). Those with a poor esophageal clearance pattern (n = 5) reported no concurrent GERD symptoms.

conclusionThe incidence of GERD burden after LHM+T is relatively low; however, the nuances relevant to accurate diagnosis in treated achalasia patients must be considered. Symptom correlation to abnormal pH study is unreliable making objective postoperative testing important. Furthermore, manual review of abnormal pH studies is necessary to distinguish GERD from poor esophageal clearance.
