RESUMO

BACKGROUND: Food bolus esophageal impaction is often the first symptom in patients diagnosed with eosinophilic esophagitis, representing a change in the epidemiology and management of this urgency. AIM: To detect eosinophilic esophagitis predictive factors in patients with esophageal impaction due to food bolus. METHODS: Patients seen for foreign body impaction were retrospectively analyzed. Epidemiologic characteristics, endoscopic findings, and impaction history were studied. The statistical analysis was carried out using the Student's t test and the chi square test and a logistic regression model. RESULTS: Of the 131 patients, 65% were men and the mean age was 56 years. The endoscopic suspicion of eosinophilic esophagitis was the most frequent finding in patients with food bolus impaction (n=89); those patients that did not have histologic confirmation were excluded (n=7). The remaining patients (n=82) were divided into two groups: confirmed eosinophilic esophagitis (Group A) (n=18) and other endoscopic findings (Group B) (n=64). Group A presented with a lower mean age (36.47 vs. 64.45, P=.001) and a more frequent past history of impaction (38% vs. 6%, OR=15.70, 95% CI (3.60-62.50), P=.001) than Group B. Age and impaction history acted as predictors for eosinophilic esophagitis with 82% sensitivity, 80% specificity, and 84% diagnostic accuracy (P<.001). CONCLUSIONS: Age and a history of impaction predict the presence of eosinophilic esophagitis in patients with food bolus impaction.

RESUMO

BACKGROUND: The use of self-expanding biodegradable prosthesis treatment of refractory benign stenosis is still undefined. OBJECTIVE: To determine the utility and safety of biodegradable polydioxanone prostheses as treatment of gastrointestinal tract refractory benign strictures. METHODS: Consecutive patients diagnosed with refractory benign stricture of gastrointestinal tract following Kochman's criteria were included. The type of stenosis were anastomotic (n = 5), peptic (n = 1), post-radiotherapy (n = 1) and they were located in proximal esophagus-hypofarynge (n = 2), esophagus medium (n = 1), distal esophagus (n = 2) and rectum (n = 2). The prosthesis was placed under endoscopic and fluoroscopic control under conscious sedation with propofol. RESULTS: Seven patients (8 prosthesis) were included. Mean patient age was 49 years-old (range: 37-70). Insertion prosthesis was successful in all cases. Distal migration of prosthesis was observed in both rectal stenosis and was the indication of a second prosthesis placement in one case. At the end of follow-up (median follow-up 30 weeks for esophageal stricture, 33 weeks for rectal stricture) 5 patients remained asymptomatic. Eighty per cent of patients with esophageal stenosis showed partial and transient re-stenosis due to hyperplastic reaction during the degradation of the prosthesis, with transient dysphagia in two patients resolved medically. Complete prosthesis degradation was confirmed by endoscopy in all cases. CONCLUSIONS: The use of self-expanding biodegradable polydioxanone prosthesis is a safe and utile therapeutic option for refractory benign gastrointestinal stenosis.
