Abstract
Background
Intramural esophageal bronchogenic cysts (EBCs) are rare congenital malformations.
Differences in reports on the clinical features of intramural EBCs and some controversies
about the treatment strategy for intramural EBCs exist.
Objectives
To investigate the clinical characteristics of intramural EBCs and evaluate the safety
and efficacy of endoscopic resection.
Methods
The clinical and endoscopic features, endoscopic resection treatment, postoperative
adverse events, and follow-up results of 17 patients with intramural EBCs were retrospectively
studied.
Results
Intramural EBCs exhibited male predominance with a male/female ratio of 58.8% (10/7)
and were predominantly found in the distal esophagus. Approximately 94.1% of patients
presented with gastrointestinal symptoms. All lesions were protruding masses covered
by intact mucosal epithelium. The morphologies of intramural EBCs were diverse under
white light endoscopy. On endoscopic ultrasonography, intramural EBCs presented as
homogeneous or inhomogeneous hypoechoic or anechoic lesions. Eleven lesions originated
from the muscularis propria, which underwent submucosal tunnel endoscopic resection
(STER), and six lesions were from the submucosa, which underwent endoscopic submucosal
dissection (ESD). Approximately 88.2% of patients underwent complete endoscopic resection.
No serious pneumothorax, bleeding, pleural effusion, esophagotracheal fistula, or
other adverse events occurred in all patients after endoscopic resection, and no cyst
recurrence, metastasis, or esophageal scar stenosis was observed during the follow-up
period.
Conclusions
Intramural EBCs can be treated by digestive endoscopic surgery. STER and ESD are safe,
effective, and minimally invasive resection methods.
