    Abstract:
    BACKGROUND: Surgery, as well as conservative treatment, in patients with clinically apparent intrathoracic anastomotic leaks are often associated with poor results and carry a high morbidity and mortality. This report describes our results with the endoscopic treatment of intrathoracic anastomotic leakages. PATIENTS: 27 consecutive patients presenting with clinically apparent intrathoracic anastomotic leak, caused by resection of an epiphrenic diverticulum (n=1), esophagectomy for esophageal cancer (n=19), limited resection for carcinoma of the gastroesophageal junction (n=1) or gastrectomy for gastric cancer (n=6) were endoscopically treated. The extent of the dehiscences ranged from about 10-70%. After endoscopic lavage and debridement of the leakage (mean duration: 16,8 days) the leaks were closed with fibrin clue (n=9) or endoclips (n=2) in cases of smaller leaks or by stent placement (n=11), stent placement after unsuccessful fibrin clue injections (n=3) or stent placement and endoclipping (n=1) in patients with a large leakage. Simultaneously the periesophageal mediastinum was drained by chest drains. RESULTS: 25 of 27 patients were successfully treated endoscopically. Under endoscopic treatment one patient died due to septic multiorgan failure. Another patient developed a refractory, persistent leak. Procedure related complications (stent migration, anastomotic stenosis) were obtained in 6 patients. CONCLUSION: An endoscopic approach is successful and safe to treat symptomatic intrathoracic anastomotic leaks smaller than 70% of the circumference. An endoscopic lavage and debridement of the leak, prior to leak closure, seems to be helpful to reduce mediastinal and pleural inflammation. In patients with smaller leaks (<30%) fibrin clue injections and endoclipping is recommended. Patients with a dehiscence from 30-70% of the circumference profit from stent placement.
