Outcomes of Long Pouch Gastric Bypass (LPGB): 4-Year Experience in Primary and Revision Cases.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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
backgroundOne of the most important complications of the one anastomosis gastric bypass (OAGB) is enterobilio acid reflux (EBAR). We report the concept of the long pouch Roux-en-Y gastric bypass (LPRYGB) meaning a Roux-en-Y with a long pouch and a 100-cm alimentary limb to avoid EBAR, with a long biliopancreatic limb to increase metabolic effects.
methodsA total of 300 LPRYGB cases in a 4-year period, with a 90% follow-up rate, were analysed. Anthropometric, technical feasibility, morbidity, weight loss and comorbidity outcomes were analysed.
resultsThe percentage total weight loss (%TWL) was 30.5% at 4 years of follow-up (32.3% in primary and 28.3% in revisions). Six intra-operative (2%) and 28 postoperative complications (9.3%) were seen. Out of this 28 complications, 11 (3.6%) were late complications. Reoperations were performed in 15 patients (5.0%). Clinically relevant EBAR was present in 3 cases only (1%) 4 years after the operation.
conclusionsThe LPRYGB combines the main advantages of the OAGB (light restriction and moderate malabsorption) with the anti-reflux effect from the Roux-en-Y diversion.
