Small Bowel Perforation in Roux-en-Y Gastric Bypass (RYGB) Secondary to Apolipoprotein A-IV (AApoA-IV) Type Amyloidosis.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundApoA-IV amyloidosis is a rare disease that involves the deposition of ApoA-IV protein aggregates in tissues. It commonly presents as cardiac or renal disease, but can, in rare cases, cause small bowel perforation.
methodsThis study describes a case of ApoA-IV type amyloidosis causing small bowel perforation after conversion of a sleeve gastrectomy (SG) into a RYGB in a Crohn's disease (CD) and rheumatoid arthritis (RA) patient. It also considers the indications for bariatric and anti-reflux surgery in the setting of co-morbid inflammatory bowel disease (IBD), gastro-oesophageal reflux disease (GORD), and obesity.
resultsObesity can reduce the efficacy of IBD medications and drives a pro-inflammatory state that may worsen IBD, however IBD patients present an operative challenge due to risk of more intestinal adhesions, potential intolerance to intestinal bypass, and risk of affecting options for future bowel resections if required. SG is often chosen over RYGB for CD patients due to limited short-term complications. However, when considering co-morbid GORD, the long-term risk of medication resistant GORD, erosive oesophagitis, and Barrett's oesophagus with SG is significant, especially given that SG is an irreversible procedure.
conclusionThere is growing evidence that bariatric surgery in IBD patients is both safe and effective, however the decision to perform bariatric surgery in an IBD patient involves consideration of the intricate interplay between obesity and IBD.
