RESUMO
BACKGROUND: With the increasing incidence of upper digestive tract tumors, more upper digestive tract surgeries are performed each year, and surgeons have difficulty in the postoperative management of gastrointestinal anastomotic fistula. The use of a new minimally invasive technique, endoluminal vacuum-assisted closure (E-VAC), has increased the success rate of the treatment of gastrointestinal fistula. METHODS: We present 6 cases of gastrointestinal fistula treated in our hospital in 2021: 3 cases of anastomotic fistula after esophageal cancer surgery, 2 cases of anastomotic fistula after gastric cancer surgery, and one case of esophageal rupture after trauma. With E-VAC and other adjuvant treatment measures, the gastrointestinal fistulas were eventually closed or significantly reduced. RESULTS: Both local and systemic infections in all 6 patients were controlled with the use of E-VAC device, resulting in significant reduction or closure of fistulas. CONCLUSION: E-VAC devices can effectively help in the removal of the exudate and necrotic tissue around the fistula, promote the proliferation of granulation tissue, and support closure of the fistula. However, further improvements to the device are needed to improve patient comfort and operational safety.
