RiMini Trial: BMI Outcomes After Bariatric Surgery at 4 Months and 1 Year

214 patients were randomized in a single-center trial comparing ring-augmented and conventional one-anastomosis gastric bypass (OAGB). The dataset, authored by Maureen Tissink and last updated in June 2026, reports short-term outcomes including peri-operative safety, adverse events, and weight outcomes up to one year postoperatively.

Use Cases

• Comparing weight loss efficacy between surgical techniques based on reported %TWL and %EWL metrics.
• Analyzing peri-operative safety profiles based on reported complication rates and Clavien-Dindo classifications.
• Studying the short-term impact of device augmentation (Minimizer ring) in bariatric surgery based on the trial's intervention groups.

Strengths

• Data originates from a randomized controlled trial (RCT) with 214 patients, providing a structured study design.
• Includes specific outcome metrics such as mean BMI (28 kg/m²) and weight loss percentages (%TWL, %EWL) with p-values.
• Reports on both intention-to-treat and per-protocol analyses, which may indicate methodological rigor.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope and likely a summary of results rather than patient-level data.
