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

backgroundLong-term data on the likelihood of undergoing additional related operations after Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) remain scarce.

objectivesThe aims of this study are to identify the long-term incidence of bariatric related operations, patient's predictive factors, and most common operations in the 15-20 years following LRYGB.

settingSingle Academic Institution, Center of Bariatric Excellence.

methodsWe performed a retrospective analysis of all LRYGB performed at Single Institution from 2003 to 2008. All subsequent bariatric related operations performed were manually reviewed, excluding upper endoscopies. Kaplan-Meier analysis was utilized to estimate the time to procedure. Cox regression was used to determine patient's factors associated with time until procedure.

resultsOf the 665 patients included, the median follow-up was 14 years. There were 248 (37.3%) patients with a related operation. After excluding panniculectomy, 199 (29.9%) had a related operation. The 3 most common operations were panniculectomy [n = 77 (12%)], followed by cholecystectomy [n = 64 (10%)], and internal hernia repair [n = 56 (8%)]. The Kaplan-Meier estimated incidence of related operation at 15 years was 43.7% and 35.3% after excluding panniculectomy. Females (HR = 1.77, 95% CI = [1.20, 2.62, p = 0.0039), age < 50 (HR = 1.42, 95% CI = [1.07, 1.88], p = 0.014), and BMI > 60 (HR = 2.77, 95% CI = [1.30, 5.91], p = 0.0083) were more likely to have a related operation.

conclusionBariatric related operations are common after LRYGB. Nearly half of patients will eventually undergo a secondary operation as they approach 20 years post-LRYGB.
