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

backgroundThe increasing prevalence of bariatric procedures has led to a surge in revisional surgeries. Failure of bariatric surgery can be attributed to inadequate weight loss or complications necessitating revisional surgery. In this study, we investigated the indications and outcomes of revisional surgery due to complications following primary bariatric surgery. MATERIALS AND

methodsA retrospective study was conducted using data from the Tehran Obesity Treatment Study, which included patients who underwent revisional bariatric surgery between March 2013 and September 2021 due to complications following primary bariatric surgery.

resultsOf the 5382 patients who underwent primary bariatric surgery (sleeve gastrectomy, one-anastomosis gastric bypass, and Roux-en-Y gastric bypass), 203 (3.70%) required revisional surgery, with 37 cases performed due to surgical complications. The indications of revisional operations were gastroesophageal reflux disease (GERD) (n=17, 45.9%), protein-calorie malnutrition (PCM) (n=14, 37.8%), unexplained abdominal pain (n=5, 13.5%), and phytobezoar (n=1, 0.03%). In the postoperative follow-up, most patients exhibited improvement in signs and symptoms related to underlying causes. However, eight patients experienced early or late complications of grade III or higher according to the Clavien-Dindo classification, with one death resulting from liver failure.

conclusionRevisional bariatric surgery may effectively address complications from primary bariatric surgery, with the majority of patients experiencing improvements in symptoms. While the overall incidence of revisional surgery due to complications is relatively low, our findings suggest that GERD and PCM are the most common indications for revisional surgery.
