Novel endoscopic management of gastroenterological anastomosis leakage by injecting gel-forming solutions: an experimental animal study.

This preclinical study demonstrated that the therapeutic injection method for gastroenterological AL using gel-forming solutions could be an alternative endoscopic treatment, especially in patients with severe conditions or comorbidities. The optimal target of this treatment is small size and early AL without poor blood flow or intense hypertrophic scar lesions.
