Esophageal fistulas occurred in 4 (9%) of 46 penetrating esophageal wounds.
All four patients with fistulas were victims of gunshot wounds, presented
in shock, and underwent an urgent tracheostomy in the emergency department.
Shock and urgent tracheostomy were significantly associated with fistula
formation. Whether single-layer closures are adequate for esophageal wounds
remains unanswered. Our data showed no disadvantage to single-layer
closure, since seven of eight were successful. This compares with a success
rate for multilayer closures of 32 of 35. Fifty percent of the esophageal
fistulas were asymptomatic and were discovered on routine postoperative
contrast study. All fistulas closed with nonoperative management.
Management recommendations included nonoperative means to establish an
airway, meticulous debridement, two-layer closure of the wound,
closed-suction drainage, and postoperative esophagography before drain
removal.
