Objective Primary tracheobronchial tumors (PTTs) are rare heterogeneous lesions arising from any part of the tracheobronchial tree. Nonspecific symptoms may lead to delayed diagnosis that requires more aggressive surgical treatment. An analysis of cases collected by the International Network of Pediatric Airway Team was undertaken to ensure proper insight into the behavior and management of PTTs. Methods Patients <18 years of age with a histological confirmation of PTT diagnosed from 2000 to 2015 were included in this multicenter international retrospective study. Medical records, treatment modalities, and outcomes were analyzed. The patient presentation, tumor management, and clinical course were compared between malignant and benign histotypes. Clinical and surgical variables that might influence event‐free survival were considered. Results Among the 78 children identified, PTTs were more likely to be malignant than benign; bronchial carcinoid tumor (n = 31; 40%) was the most common histological subtype, followed by inflammatory myofibroblastic tumor (n = 19; 25%) and mucoepidermoid carcinoma (n = 15; 19%). Regarding symptoms at presentation, wheezing (P = 0.001) and dyspnea (P = 0.03) were more often associated with benign growth, whereas hemoptysis was more frequently associated with malignancy (P = 0.042). Factors that significantly worsened event‐free survival were age at diagnosis earlier than 112 months (P = 0.0035) and duration of symptoms lasting more than 2 months (P = 0.0029). Conclusion The results of this international study provide important information regarding the clinical presentation, diagnostic workup, and treatment of PTTs in children, casting new light on the biological behavior of PTTs to ensure appropriate treatments.

Tolerance and safety between the intestinal preparation for 1-day colonoscopy with PEG 3350 (4g/kg/day) + bisacodyl and the 2-day preparation with PEG 3350 (2g/kg/day) + bisacodyl were similar. The quality of cleanliness was good in both groups, being partially more effective in the 1-day group with PEG 3350 (4g/kg/day).

Introduction. Surgical repair of recurrent tracheoesophageal fistula has a high risk of complications. Therefore, various endoscopic techniques have been used to avoid complications.Objective. To understand the usefulness of trichloroacetic acid endoscopic application for the treatment of recurrent tracheoesophageal fistula.Materials and methods. An observational, descriptive, retrospective, case-series-based study was carried out in a tertiary pediatric hospital. Records of patients with recurrent tracheoesophageal fistula from 2015 to 2021 were reviewed. All patients within this period underwent brushing and trichloroacetic acid application.Results. Mean time of recurrent tracheoesophageal fistula occurrence was 4.8 months (range: 1-19.2). Two patients had a small fistula (less than 4 mm), three patients had a medium fistula (4 mm), and two patients had a large fistula (more than 4 mm). Mean sessions for fistula closure were 2.2 (range: 1-4). Mean time between procedures was 22 days (range: 14-30). Mean follow-up since fistula closure confirmation was 33 months (range: 9-72), during which no recurrences were noted.Conclusion. Endoscopic management of recurrent transesophageal fistula with trichloroacetic acid is a safe and effective procedure. Brushing and trichloroacetic acid combined improve success rates. Fistulas over 4 mm in diameter require more procedures. However, a larger patient cohort and a longer follow-up period are needed to confirm this.
