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.

Abstract

backgroundSleeve gastrectomy (SG) has become the most popular bariatric procedure worldwide. However, SG is associated with de novo gastroesophageal reflux (GERD) and esophagitis, with concerns for progression into Barrett's esophagus (BE). The purpose of this study is to assess the clinical and endoscopic progression of GERD, esophagitis, and BE 3 to 4 years after SG.

methodsFifty-eight patients (pts) were assessed with endoscopy preoperative and at 3 to 4 years post SG, representing 44.9% follow-up. Endoscopy was offered to all SG pts regardless of symptoms. Outcomes including percent total weight loss (%TWL), PPI use, esophagitis progression, de novo reflux, and BE formation.

resultsAt post-op follow-up, the %TWL was 23%. The average BMI dropped from 49.07 to 37.5. De novo reflux developed in 13 pts (30.9%). Of the 16 pts with GERD pre-op, 37.5% improved, 25% had stable disease, and 37.5% had worsening symptoms. The rate of esophagitis nearly doubled from 37.9% pre-op to 70.6% post-op. A majority of post-op pts had mild esophagitis (87.8%), with 12.1% with LA classes C and D. Asymptomatic esophagitis was found in 68.2% of post-op pts. The incidence of BE was 12.7% post-op, with de novo BE developing in 4 pts, representing 7.2%.

conclusionSG is associated with increased rates of asymptomatic esophagitis and de novo reflux at 3 to 4 years post-op. De novo BE was detected as well, highlighting the importance of post-op screening. The majority of pts with GERD pre-op have stable disease or improve.
