Endoscopic Treatment of Anastomotic Leakage in the Upper Gastrointestinal Tract

Anastomotic leakage (AL) in the upper gastrointestinal tract (uGIT) is a critical condition associated with high mortality and significant morbidity. Effective management requires prompt and specialized diagnostic and therapeutic interventions through an interdisciplinary approach. In current practice, surgical intervention is infrequent and typically reserved for cases of extensive damage. Close collaboration between radiology, endoscopy, and surgery is essential for optimal care. Endoscopic therapy is the primary modality for managing AI in the upper GIT. This review offers an overview of the most common endoscopic treatment strategies for AL in this region.

Significant advancements have been made in the endoscopic management of AL in the uGIT in recent years. Endoscopic sutures and clips remain appropriate for smaller defects, but for larger leakages, endoscopic vacuum therapy (EVT) is gaining prominence over stent placement. Innovative approaches, such as vacuum stents and small diameter filmed drainage (FD), offer promising new therapeutic options for treating AL in the uGIT.

(1) Endoscopy plays a pivotal role in the management of AL in the upper GIT. (2) A growing body of evidence supports EVT as superior to other modalities such as sutures, tissue sealants, or clips. Notably, EVT has a lower complication rate and higher healing success compared to stent therapy in AL treatment. (3) New endoscopic techniques, including the vacuum stent and FD, represent promising advancements in the treatment of AL.
