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.

Abstract

introductionBariatric surgery remains underutilized despite rising global obesity rates, with less than 2% of eligible patients undergoing procedures annually. Magnetic compression anastomosis (MCA) offers potential advantages over traditional techniques, including reduced operative time and improved healing. However, delayed patency has limited its application. This study evaluates the novel OTOLoc™ system, which enables immediate patency in Roux-en-Y gastric bypass (RYGB) via self-forming magnets (SFMs), addressing a key limitation of prior MCA approaches.

methodsA prospective, open-label, multicenter study (NCT06199635) was conducted across two centers (India and Chile). Fourteen patients with moderate-to-severe obesity underwent RYGB with SFM-assisted jejuno-jejunal anastomosis. Primary outcomes included 30-day freedom from anastomotic adverse events (AEs; leaks, bleeding, obstruction). Secondary outcomes encompassed weight loss, comorbidity resolution, and nutritional status. Technical success was defined as anastomosis creation without conversion to sutures/staplers.

resultsAll 14 procedures (median age: 42 years, BMI: 41.4 kg/m

conclusionThe OTOLoc™ system safely facilitated immediate-patency magnetic anastomoses in RYGB, with no device-related complications and promising short-term efficacy. Larger studies comparing SFMs to stapled anastomoses are warranted to validate these findings and assess long-term outcomes.
