Objectives/Hypothesis:
To evaluate the clinical features of children with type I and type II laryngeal cleft and the role of conservative monitoring versus endoscopic repair in their management.
Methods:
Clinical presentation and evaluation; findings at the time of laryngoscopy, bronchoscopy, and esophagoscopy; and efficacy and outcome of conservative monitoring and endoscopic CO(2) laser repair.
Results:
Eighty-one patients were evaluated for aspiration. Seventy-four patients were diagnosed as having a clinically significant laryngeal cleft. Thirty-two patients (14 males, 18 females) were monitored conservatively. Forty-nine patients (26 males, 23 females) required surgical intervention due to failed medical and feeding therapy of aspiration related to their laryngeal clefts (28 type I, 21 type II). Endoscopic CO(2) laser repair was used in all these patients.
Conclusions:
Medical and feeding therapy should be the first modality of treatment in patients with laryngeal cleft type I and type II. Factors supporting surgical repair include: 1) clinically apparent aspiration with feeding, 2) severity of pulmonary status, 3) findings on modified barium swallow and chest x-ray, 4) absence of significant comorbid conditions predisposing to aspiration, 5) findings on upper aerodigestive endoscopy, and 6) poor response to medical management and feeding therapy.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
