RiMini Trial: Weight Loss Outcomes for Ring-Augmented vs. Conventional Gastric Bypass

Between July 2022 and December 2023, 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 updated in 2026, reports short-term outcomes including peri-operative safety, adverse events, and weight loss percentages (%TWL and %EWL) at one year postoperatively.

Use Cases

• Compare weight loss efficacy (%TWL and %EWL) between two surgical techniques based on the trial results.
• Analyze peri-operative and postoperative complication rates (Clavien-Dindo classification) for surgical safety assessment.
• Investigate the relationship between operation time and patient outcomes in bariatric procedures.
• Conduct intention-to-treat and per-protocol analyses on clinical trial data for methodological validation.

Strengths

• Data from a randomized controlled trial with 214 patients (107 per group), providing a structured comparison.
• Includes specific, reported metrics such as mean operation time (51 minutes ±13) and one-year weight loss percentages (%TWL 33% vs 31%).
• Clear temporal scope for patient enrollment (July 2022 to December 2023) and one-year follow-up.

Limitations

• Row count and column-level documentation are 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.
• Data is from a single-center trial, which may limit generalizability.
