Hemostatic Spray TC-325 (Hemospray®) and Unexpected Esophageal Entrapment of Gastroscope With Airway Management Considerations: A Case Report.

Bleeding from the upper gastrointestinal tract is responsible for approximately 2% of all hospital admissions annually, with an up to 17% mortality rate. Therapeutic endoscopic interventions are often indicated for establishing hemostasis. These interventions include but are not limited to thermal coagulation with cautery, mechanical methods using band ligation or hemostatic clips, and hemostatic spray. Anesthesia providers are frequently involved in providing sedation for those endoscopic procedures. In 2018, the United States Food and Drug Administration approved a hemostatic spray, Hemospray® TC-325 (Cook Medical, Winston- Salem, NC, USA) for controlling nonvariceal upper gastrointestinal bleeding. The inorganic, mineral-based powder forms a mechanical tamponade by absorbing water and attracting clotting factors to the bleeding site. Adverse events associated with using the product are reported as rare but have included perforation and difficulty in removing the gastroscope. This case presents unexpected entrapment of the gastroscope in a patient's esophagus after the bleeding site was treated with Hemospray. Potential difficulties with airway management strategies are discussed.
