Esophageal duplication cyst

An Uncommon Cause of Recurrent Dysphagia and Chest Pain in an Adolescent Boy

An 11-year-old boy was brought to the emergency department with a week-long history of widespread pain in his upper abdomen that worsened with deep breathing and eating, sialorrhea, food impaction sensation, and a recent fever. Ten months prior, he had similar symptoms and was diagnosed with a pharyngeal phlegmon. He was treated with antibiotics and dexamethasone. In the current episode, he presented with mild elevation of inflammatory markers, a slight deviation of the trachea on chest X-ray, and a tubular esophageal duplication was identified on a thoracic CT, with its opening observed during the endoscopic study. The patient was admitted for further treatment with fluids, analgesia, and antibiotics, and showed improvement over the next seven days with no significant incidents. Esophageal duplications are a rare congenital anomaly and their exact cause is unknown. Typically found in the posterior mediastinum and lower esophagus, they can cause symptoms such as pain, dysphagia, regurgitation, and malnutrition. Surgical or endoscopic resection can be a treatment option for these malformations.

Esophageal Duplication Cysts in 97 Adult Patients: A Systematic Review

BACKGROUND

Esophageal duplication cysts are a rare congenital cystic malformation from faulty intrauterine recanalization of the esophagus during the 4-8^th weeks of development. They account for 20% of all gastrointestinal duplication cysts and commonly involve the distal esophagus. Presenting symptoms may be related to size and location.

MATERIALS AND METHODS

Following the PRISMA guidelines, a systematic review was performed by searching published literature in various databases. Data from 97 reported case reports were pooled to present a descriptive and statistical analysis.

RESULTS

Patient population was composed of 51(52.5%) males and 46 (47.5%) females, and mean ages was 42.3 years (18-77). Distal cysts were the most prevalent. Seventy-nine (81.4%) patients were symptomatic; common symptoms included dysphagia, chest pain, cough and weight loss. Fifteen (15.5%) patients were treated conservatively and 75 (84.5%) by surgical treatment, among them thoracotomy in 30 (30.9%) patients and VATS in 17 (17.5%) patients. Mean length of hospital stay was 8.6 days (range: 1-26 days). One fatality was registered. Location, unlike size, was not found to influence presenting symptoms or treatment employed. Frequency of conservative treatment was not significantly different between symptomatic and asymptomatic patients. Open approaches were associated with longer stays than their minimally invasive counterparts.

CONCLUSION

Esophageal duplication cysts remain rare in adults and are frequently located in the distal esophagus. Larger cysts are more likely to cause symptoms. Various surgical techniques may successfully be employed in the treatment of this pathology. Minimally invasive procedures have a shorter hospital stay.

Communicating Tubular Esophageal Duplication Combined with Bronchoesophageal Fistula

Esophageal duplication (ED) is rarely diagnosed in adults and is usually asymptomatic. Especially, ED that is connected to the esophagus through a tubular communication and combined with bronchoesophageal fistula (BEF) is extremely rare and has never been reported in the English literature. This condition is very difficult to diagnose. Although some combinations of several modalities, such as upper gastrointestinal endoscopy, esophagography, computed tomography, magnetic resonance imaging, and endoscopic ultrasonography, can be used for the diagnosis, the results might be inconclusive. Here, we report on a patient with communicating tubular ED that was incidentally diagnosed on the basis of endoscopy and esophagography during the postoperational evaluation of BEF.
