339. MANAGEMENT OF OESOPHAGO-PLEURAL FISTULAS WITH ENDOSCOPIC VACUUM THERAPY: A PROMISING APPROACH

Abstract Background Boerhaave syndrome is a rare and serious condition requiring prompt management to prevent severe complications and improve patient outcomes. One significant complication is an oesophago-pleural fistula. These fistulas often result in aspiration pneumonia, empyema, and mediastinitis. Conventional management with surgery has high complication and mortality rates. Endoscopic vacuum therapy (EVT) is a less invasive technique for the management of oesophageal fistulas, involving endoscopic placement of a vacuum-assisted sponge within the oesophageal defect, promoting healing via continuous wound drainage and tissue granulation. Methods We report the case of a gentleman who initially presented with Boerhaave syndrome, was treated with open oesophageal repair, and was re-admitted 3 weeks later for an oesophago-pleural fistula with pleural collections. EVT was administered to the oesophageal defect twice weekly for 29 days and the effectiveness of therapy was monitored with serial oesophagogastroduodenoscopies, contrast studies, and computed tomography scans of the thorax to monitor the resolution of the pleural collections. During this period, the fistula defect showed gradual granulation tissue growth, resulting in full closure of the mucosal defect. Results The use of EVT has shown to result in successful closure of fistulas, resolution of sepsis with reduced need for surgical intervention, and shorter hospital stays. EVT combines coverage of the oesophageal defect and adequate drainage of the cavity behind the defect, often without the need for additional external drain placement. These findings highlight the role of EVT as a valuable adjunct in the management of oesophageal fistulas, particularly in cases requiring rescue therapy. Limitations of EVT include risk of bleeding, fistula formation/recurrence, need for frequent endoscopic interventions, stricture formation, and inability for oral intake due to occlusion of the gastrointestinal tract. Conclusion EVT represents a paradigm shift in the management of oesophageal fistulas, offering a less invasive alternative with the ability to promote wound healing, control sepsis, and reduce the need for high-risk redo oesophageal surgery. Further prospective studies and trials are needed to reach a consensus about its technical aspects, such as pressure settings and procedure intervals; as well as to evaluate its efficacy as a potential first-line treatment for oesophageal fistulas.
