Background: Revision surgery to eliminate a gastrogastric fistula (GGF) is often associated with high morbidity. Methods: This report describes a percutaneous transgastric approach for revision surgery in three patients with GGF using a transgastric, totally extraperitoneal approach. Results: The access was performed successfully in all the patients. There were no intraoperative complications, and the patients had an uneventful recovery. One patient had a recurrence 8 months after the procedure but had achieved satisfactory weight loss during the period. We were able to perform a second percutaneous transgastric repair. The second patient showed an asymptomatic recurrence of the fistula, which was later completely repaired. The third patient has had moderate weight loss. Conclusions: Although current results are not optimal, we believe that this approach could represent an alternative for patients with a hostile abdomen or in whom co-morbidities comprise a prohibitive factor. Further experience, technical improvements, and longer follow-up are needed to evaluate and optimize this approach and evaluate its potential use in other surgical areas.
