Endoscopic management of refractory leaks and fistulas after bariatric surgery with long-term follow-up.

Complex multi-modality endoscopic management ultimately achieved clinical success in most cases of refractory leaks/fistulas post-bariatric with an acceptable safety profile. However, a close follow-up to detect the development of long-term failure is warranted. These patients should be referred to a specialized bariatric center with expertise in bariatric endoscopy and surgery.
