About

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.

Enrollment: 199 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Adult patients (≥ 18years) who underwent reversal of RYGB between 2007 and 2023.

Exclusion criteria

• Emergency reversal due to bowel ischemia
• Reversal following other bariatric procedures (e.g. gastric banding)
• Partial/functional reversals (e.g., gastro-gastric fistula or anastomosis between the Roux-limb and gastric remnant, without full reversal of RYGB)
