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

backgroundGastrojejunostomy (GJ) stricture is one of the most commonly recognized complications following laparoscopic Roux-en-Y gastric bypass (LRYGB). The risks involving the formation of early GJ stomal stenosis are largely unknown. The aims of this study are to evaluate the rate and risk factors associated with GJ stricture in patients requiring esophagogastroduodenoscopy (EGD) within 30 days after LRYGB.

methodsThis is a retrospective study of patients who underwent EGD for GJ stricture following LRYGB. Data were retrieved from MBSAQIP database from 2015 to 2018. Descriptive, bivariate, and logistic regression analyses were performed. Those who had reoperation, readmission, and intervention for other indications rather than GJ stricture were excluded from the risk factor analysis.

results760,076 patients underwent bariatric surgery. Of these, 184,660 (24.3%) underwent LRYGB and 875 had GJ stricture within 30 days postoperatively. The overall incidence of early GJ stricture after LRYGB was 4.7 per 1000 person-years. The incidence decreased from 6.2 to 3.4 per 1000 person-years during the 4-year period. 85% of patients with GJ stricture required therapeutic intervention. Median (IQR) day to the first endoscopic intervention was 25 (21-28) days. The overall 30-day readmission rate was 40%. 30-day reoperation rate due to GJ stricture was 5.6%. No 30-day mortality occurred. Factors independently associated with an increased risk for early GJ stricture include concurrent hiatal hernia repair (Adjusted Odds Ratio-AOR 1.8, 95% CI 1.5-2.2), revision case (AOR 1.4, 95% CI 1.1-1.6), African American (AOR 1.4, 95% CI 1.2-1.7), gastroesophageal reflux disease-GERD (AOR 1.4, 95% CI 1.2-1.5), drain placement (AOR 1.3, 95% CI1.1-1.4), and routine postoperative swallow study (AOR 1.3, 95% CI 1.1-1.50).

conclusionThe incidence of early GJ stricture following LRYGB decreased at MBSAQIP-accredited centers over the review period. Patients having additional manipulation at or around GJ were at risk of developing early GJ stricture after LRYGB.
