Transgastric drainage of the perforated esophagus: our experiences over 10 years.

Abstract

We first described the technique of transgastric drainage of esophageal injuries in 2008. The method establishes vacuum drainage of the lumen of the esophagus, while maintaining patency, effectively exteriorizing the perforation to allow healing. We summarize this technique and present our experiences from the largest published series of patients. Our unit has treated selected esophageal injuries with transgastric drainage for 10 years. Indications include perforations not amenable to primary repair and treatment failure following prior surgical intervention. A 36 French silastic chest drain is pulled through the abdominal and stomach wall and introduced into the esophagus so that it crosses the perforation. Gastropexy is performed. Mediastinal decontamination and drainage are performed as needed. Continuous suction of -10 cm water is applied. Leak resolution is assessed with weekly water-soluble swallows. For this retrospective observational study, we analyzed data for patients with esophageal perforation, between 2012 and 2022. Inpatient mortality and time to leak resolution were set as primary and secondary outcomes. Esophageal perforations were treated with transgastric drain in 35 patients, of whom 68% (n = 24) were men. Median age was 67 (26-84). Spontaneous perforations accounted for 60% (n = 21), 31% (n = 11) were iatrogenic and 6% (n = 2) were ischemic. Inpatient and 30-day mortality was 14% (n = 5). Among successful treatments, the median length to resolution of leak on imaging was 34.5 days (6-80). Transgastric drainage can successfully treat esophageal perforations, where primary repair is not feasible. The mortality rate of 14% and reduced morbidity compares favorably with other traditional methods of management for esophageal perforation.
