Outcome after failed initial therapy for rupture of the esophagus or intrathoracic stomach

Abstract

Survival after rupture of the esophagus or intrathoracic stomach is improving, but continued leakage after initial therapy remains a problem. We retrospectively reviewed patients with rupture of the esophagus or intrathoracic stomach to determine the prevalence of continued leakage after initial therapy and how this complication affects outcome. Our review included 58 patients, 38 (66%) of whom had preexisting esophageal disease. The etiology of perforation was spontaneous rupture in 17, penetrating trauma in four, and iatrogenic injury in 35; two patients had perforation from other causes. Initial therapy consisted of drainage in eight, primary repair in 24, resection in 18, bypass in two, and observation in six. The overall mortality rate was 12% (7 of 58 patients) and continuing leaks were identified in 21% (12 of 58 patients). These leaks were unrelated to patient age, existence of prior disease, or delay in therapy but were more common after initial treatment by primary repair with or without pleural flap coverage compared to other management strategies (6 of 9 vs. 6 of 49; P < 0.001). Salvage therapy with survival was possible in 10 (83%) of 12 patients by means of esophagectomy in four, exclusion in one, drainage in two, or observation in three. Continuing leaks can be avoided by providing soft tissue coverage other than pleura over a primary repair and by not leaving an intrathoracic esophageal stump. Aggressive management of continuing leaks results in survival in more than 80% of patients.
