Treatment of esophageal leakages with the Microtech-VAC-Stent: a monocentric early experience of three cases.

BACKGROUND

Endoscopic approaches in the treatment of transmural esophageal defects, either after esophageal resection or due to perforation, have demonstrated convincing feasibility. Surgical options are limited and associated with high morbidity and mortality rates. Currently, internal endoscopic drainage with pigtail stents, self-expanding metal stent (SEMS), or endoscopic vacuum therapy (EVT) are options for first-line treatment. Here, we report the outcome of the recently developed combination of SEMS and EVT using the endoscopic Microtech-VAC-Stent (EVS).

METHODS

Between June and July 2022, three consecutive patients (one female and two males) with esophageal transmural defects were treated with the Microtech-VAC-Stent. Two patients suffered from an anastomotic leak after oncologic gastroesophageal surgery, and one patient presented with esophageal perforation due to Boerhaave syndrome.

RESULTS

Three consecutive patients were successfully treated with EVS. In one patient, one EVS treatment was sufficient, whereas the other two patients needed two and six EVS exchanges. Exchanges were scheduled every 7 days and no procedural adverse events were observed.

CONCLUSION

In line with the former case series, EVS therapy is a promising new approach for the treatment of esophageal leaks. Exchange of the EVS seems feasible every 7 days reducing interventions for the individual patient. Prospective studies comparing EVS with other endoscopic therapies are needed to define the best therapeutic approach.
