Endoscopic technique for closure of enterocutaneous fistulas

Abstract

Background and objectives

Endoscopic over the scope clip (OTSC) closure represents a new technique for endoscopic management of enteric bleeding and tissue defects such as anastomotic leaks and enterocutaneous (EC) fistulas. We aim to describe our technical approach for OTSC closure of EC fistulas and convey our outcomes.

Methods and procedures

This retrospective review includes ten patients who underwent OTSC application for EC fistulas by surgical endoscopists at a US tertiary care hospital from July 2015 to October 2017. Demographic data, along with type of defect, location, duration of lesion, success or failure of OTSC, and nutritional status were compiled. The ACS NSQIP surgical risk calculator was used to project the risk of mortality, complications, length of stay, and risk of readmission had our patients undergone surgical correction of their fistula.

Results

Overall success for EC fistula closure was 70%. Acute fistulas were closed with a success rate of 86%. Chronic fistulas were closed successfully in only 33% of cases. Of patients successfully closed, NSQIP-predicted rates of mortality, any complication, and median length of stay were 21.1%, 34.5%, and 9.5 days, respectively. With OTSC, these patients experienced 0 mortalities, 0 complications, and had a median length of stay of 4 days.

Conclusion

OTSC is an effective adjunctive measure to improving rates of successful closure of EC fistulas and compromised anastomosis. OTSC conveys a markedly improved procedural risk profile as compared to standard surgical correction.
