Esophageal dysmotility after laparoscopic gastric band surgery.
Article in Obesity surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe effect of the laparoscopic adjustable gastric band (LAGB) on the esophagus has been the subject of few studies despite recognition of its clinical importance. The aim of this study was to investigate the frequency and clinical effect of esophageal dysmotility and dilatation after LAGB.
methodsWe undertook a retrospective analysis of 50 consecutive patients with no dysmotility on perioperative video contrast swallow who underwent primary LAGB operation. All patients had serial focused postoperative contrast studies for band adjustments at least 6 months post-LAGB. Clinical and radiological outcomes were assessed.
resultsMedian follow-up time was 18 months (range 7-39 months), and the median number of contrast swallows per patient was 5. The mean excess weight loss (EWL) overall was 47 % (standard deviation (SD) 22.3). Radiological abnormalities were recorded in 17 patients (34 %, 95 % confidence interval (CI) 21-49 %), of whom 15 had radiological dysmotility and 7 had esophageal dilatation (five patients had both dysmotility and dilatation). Of these 17 patients, six (35 %) developed significant symptoms of dysphagia, gastroesophageal reflux disease (GERD) or regurgitation requiring fluid removal. In comparison, 12 of 33 (36 %) patients without radiological abnormalities developed symptoms requiring fluid removal (p = 1.00). Patients with radiological abnormalities were significantly older than those without these abnormalities. Symptoms were alleviated by removing fluid in most patients.
conclusionsThe LAGB operation results in the development of radiological esophageal dysmotility in a significant proportion of patients. It is not clear if these changes are associated with an increased risk of significant symptoms. Fluid removal can reverse these abnormalities and their associated symptoms.
