Naturally Banded Sleeve Gastrectomy Vs Non-Banded Sleeve Gastrectomy, Two Years Follow up, Controlled Clinical Trial.
Trial report in Obesity surgery, 2026. 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
introductionLaparoscopic sleeve gastrectomy (LSG) is the most common bariatric procedure. Although ring-augmented LSG reportedly improves long-term weight-loss outcomes, some are concerned about potential complications related to the foreign body. Therefore, this study aimed to examine 2 years of follow-up of banded sleeve with the patient’s own tissue, naturally banded LSG.
methodsThis prospective randomized controlled clinical trial enrolled 80 patients. It was conducted at a university hospital between November 2022 and January 2025. Patients were randomly assigned to two equal groups: Group 1, LSG plus banding using the Teres ligament or a tight omental flap, and Group 2, LSG without banding. Patients were followed up for at least 2 years.
resultsThe mean follow-up period was 25.5 months. At 2 years, the mean gastric volume was significantly smaller in Group 1 (142.3 mL) than in Group 2 (218.7 mL, p= 0.000). Additionally, the mean percentage of excess weight loss (%EWL) was significantly higher in Group 1 (87.0%) than in Group 2 (81.8%, p= 0.000). Moreover, the mean percentage of total weight loss (%TWL) was significantly higher in Group 1 (42.0%) than in Group 2 (38.0%, p= 0.034). Finally, the mean food tolerance score was significantly lower in Group 1 (21.5) than in Group 2 (22.9, p= 0.000).
conclusionsBased on 2 years of follow-up, LSG with natural banding was associated with minimal gastric pouch dilatation and greater weight loss than non-banded LSG. However, long-term follow-up data are needed.
