Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective:

To investigates incidence, indications, symptom relief, complications, and weight outcomes after Roux-en-Y gastric bypass (RYGB) reversal.

Background:

RYGB is an effective treatment for obesity, but in rare cases may be associated with severe long-term complications requiring RYGB reversal. Evidence on incidence and outcomes is limited.

Methods:

This nationwide, multi-center, retrospective cohort study included all patients undergoing RYGB reversal in Sweden between 2007 and 2023. Data were obtained from the Scandinavian Obesity Surgery Registry (SOReg) and medical records.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Adults (≥ 18years) who underwent reversal of RYGB

Included patients were adults (≥ 18years) who underwent reversal of RYGB between 2007 and 2023. Exclusion criteria included emergency reversal due to bowel ischemia, reversal following other bariatric procedures (e.g. gastric banding), or partial/functional reversals (e.g., gastro-gastric fistula or anastomosis between the Roux-limb and gastric remnant, without full reversal of RYGB)

No interventions assigned to this group
