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

backgroundSleeve gastrectomy (SG) is the most common primary bariatric surgery. Long-term, up to 20% of patients may need revisional surgery. We aimed to evaluate the short-term outcomes of various revisional bariatric surgeries after a failed primary SG.

methodsThis is a single-center retrospective study of a prospectively collected database of obese patients who underwent revisional bariatric surgery during 2010-2018 for a failed previous SG. Failure was defined as inadequate weight loss (< 50% excess weight loss), ≥ 20% weight regain of the weight lost, and presence of refractory non-reflux obesity-related comorbidities ≥ 1 year after SG. Revisions included were re-sleeve, Roux en-Y gastric bypass (RYGB), biliopancreatic diversion with duodenal switch (BPD/DS), and single-anastomosis duodenal switch (SADS). The primary outcome was weight loss after revision. Secondary outcomes included postoperative complications. Due to varying follow-up rates, short-term outcomes (≥ 6 and ≤ 18 months) were assessed. Descriptive statistics are expressed as count(percentage) or median(interquartile range).

resultsNinety-four patients met inclusion criteria. Forty-one underwent conversion to RYGB, 33 had BPD/DS, 7 had SADS, and 13 underwent re-sleeve surgery. Median interval between SG and revision was 31(27) months. At a median of 14(18) months, follow-up rate was 76% for the study cohort. Prior to revision, median BMI was 41.9(11.7) kg/m

conclusionsAt 1 year, revisional procedures offer further weight loss after a failed primary SG. Bypass-type revisions are preferred over re-sleeve surgery. In the absence of refractory reflux symptoms, duodenal switch-type procedures are safe and effective options especially in patients with severe obesity before SG.
