Revisional Surgery Due to Weight Regain or Insufficient Weight Loss Following One Anastomosis Gastric Bypass.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionOne anastomosis gastric bypass (OAGB) is a common procedure associated with satisfactory outcomes. Revisional surgery due to weight regain or insufficient weight loss (WR/IWL) after OAGB is underreported.
methodsA retrospective analysis of a single-bariatric surgeon database was conducted. All patients undergoing revisional surgery after OAGB due to WR/IWL were included.
resultsTen patients were included in this case series. The median time between OAGB and revisional surgery was 44.9 months. The median body mass index (BMI) was 41.6 at pre-OAGB and 38.6 at pre-revision. The median age at OAGB revision was 40 years. The median biliopancreatic limb (BPL) length at revision was 160 cm. BPL elongation was performed in three patients, conversion to Roux-en-Y gastric bypass (RYGB) with BPL elongation in three patients, RYGB without BPL elongation in three patients, and one patient underwent conversion to single anastomosis duodeno-ileal bypass with sleeve (SADI-S). Pouch resizing was performed in four patients. One patient was reoperated due to a staple line leak from pouch resizing after conversion to RYGB. At a mean postoperative follow-up of 19 months, the median BMI and total weight loss were 30 and 18%, respectively. Higher weight loss outcomes occurred with BPL elongation (average: 24.8%) and SADI-S (average: 23.4%), while conversion to RYGB, with or without elongation, showed lower weight loss outcomes (11.5% and 7.8%, respectively).
conclusionsWR/IWL after OAGB can be encountered during follow-up. In this case series, several options of revisions were evaluated, and BPL elongation or conversion to SADI-S correlated with better weight loss outcomes.
