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.

Oesophageal duplication cysts are a subtype of foregut cysts, associated with the presence of ectopic gastric mucosa. Gastric acid secreted by this mucosa can lead to complications. We report one such unusual case of complication leading to the formation of broncho-oesophageal fistula in a duplication cyst. A girl in her middle childhood presented with a long-duration cough and multiple respiratory infections. On investigation, a right-sided paraoesophageal air-filled cystic lesion was identified, with a possible communication with the airway, confirmed by an oral contrast study. On further workup, a positive uptake was noted on Meckel’s scan, signifying the presence of ectopic gastric mucosa. The findings were confirmed surgically and on histopathology and were consistent with a duplication cyst with broncho-oesophageal fistula. An unexplained upper respiratory tract symptomatology should mandate imaging, which would enable early detection and appropriate surgical management of such cysts in infancy and childhood.

Esophageal bronchogenic cysts are rare, and since a limited number of cases has been reported, the treatment plan for asymptomatic patients is difficult. A 55-year-old man without any symptoms visited our hospital for further examination of an esophageal mass detected on simple computed tomography. Upper endoscopy showed the protruding, submucosal mass covered by normal mucosa, and endoscopic sonography confirmed hypoechoic lesions originating from the muscularis propria. The patient was diagnosed as having an esophageal duplication cyst and underwent thoracoscopic resection. Pathological findings were consistent with an esophageal bronchogenic cyst. The patient was discharged without any problems on the 6th postoperative day. Upper endoscopy was performed 6 months after surgery, and no evidence of esophageal diverticula or narrowing was present. In conclusion, early thoracoscopic resection of esophageal bronchogenic cysts, before appearance of the symptom, can be a considerable treatment option because it is less invasive and may be advantageous for obtaining a definitive diagnosis in patients who are candidates for safe surgical resection.

A female infant presented with a month-long history of dry cough, along with two episodes of fever and increased work of breathing, requiring hospital admission and oxygen therapy. On examination, she had severe acute malnutrition, mild tachypnoea, chest retractions and reduced air entry in the left lower lung zone with occasional wheezing, though oxygen saturation was normal on room air. Chest X-ray showed left lung hyperinflation with mediastinal shift to the right. A plain CT chest done outside showed left lung hyperlucency, and bronchoscopy revealed near-complete blockage of the left main bronchus. Contrast chest CT identified a hypodense lesion in the subcarinal area, compressing the oesophagus and left main bronchus and abutting the aorta. She underwent right posterolateral thoracotomy with cyst excision and chest drain placement. Histopathology confirmed an oesophageal duplication cyst. On follow-up, left lung aeration significantly improved.

Background Intramural esophageal bronchogenic cyst is very rare. Surgical removal of the cysts is advised even the patients are asymptomatic, since the cyst can lead to complications, and there is a risk of malignant transformation. Thoracotomy or thoracoscopy is the most commonly used approach for complete excision of the cysts. To our knowledge, this is the first report to excise intramural esophageal bronchogenic cyst completely by endoscopic submucosal tunnel dissection (ESTD). Case presentation A 40-year-old male was referred to our hospital due to the detection of a submucosal tumor at the distal esophagus. The tumor was found during gastroendoscopy in a general health check-up. The patient had no symptoms. A benign esophageal tumor was confirmed by endoscopic ultrasonography (EUS) and computed tomography (CT). On the basis of these results, ESTD was performed. During the procedure, a cystic mass was observed between the mucosa and the muscular layers of the esophagus, and a hybrid knife was used for dissection. Histopathological examination showed the cyst wall was lined by pseudostratified ciliated columnar epithelium, consistent with a bronchogenic cyst. The esophagography using meglumine diatrizoate showed no leakage on the seventh day after ESTD. The patient remained asymptomatic and had a regular diet during the follow-up period. Discussion and conclusions We successfully utilized ESTD for complete removal of esophageal bronchogenic cysts originating from the muscularis propria. The approach appeared safe, providing a minimally invasive treatment option for patients.

Background Bronchogenic cysts are rare foregut abnormalities that arise from aberrant budding of the tracheobronchial tree early in embryological development. These cysts predominantly appear in the mediastinum, where they may compress nearby structures. Intra-abdominal bronchogenic cysts are rare. We report an intra-abdominal bronchogenic cyst that was excised laparoscopically. Methods A 40-year old female with a history of gastritis presented for evaluation of recurrent abdominal pain. A previous ultrasound showed cholelithiasis and a presumed portal cyst. Physical examination and laboratory findings were unremarkable. A CT scan with pancreatic protocol was performed and an intra-abdominal mass adherent to the esophagus was visualized. A laparascopic enucleation of the mass was performed. A 3-cm myotomy was made after circumferential dissection of the cyst and the decision was made intraoperatively to reapproximate the muscularis layer. A PubMed literature search on surgical management of esophageal bronchogenic cysts was subsequently performed. Results The literature search performed on the subject of esophageal bronchogenic cysts found one review article focusing on intramural esophageal bronchogenic cysts in the mediastinum and five case reports of esophageal bronchogenic cysts. Of these, only one was both intraabdominal and managed laparascopically with simple closure of the resulting myotomy. The majority of the bronchogenic cysts mentioned in the literature were located mediastinally and were managed via open thoracotomy. Our findings confirm the rarity of this particular presentation and the unique means by which this cyst was surgically excised. Conclusion This case highlights the management of a rare entity and advocates for enucleation of noncommunicating, extraluminal esophageal bronchogenic cysts and closure of the esophageal muscular layers over intact mucosa as a viable surgical approach to this unusual pathology. Other cases of laparascopic enucleation of bronchogenic cysts have shown similarly uneventful postoperative courses and rapid recovery with no apparent return of symptoms.

Bronchogenic cysts are congenital cystic lesions of foregut origin, usually intrapulmonary or mediastinal, while esophageal cysts generally originate within the esophagus. To the best of our knowledge, this is the first report of a case of a completely intramural bronchogenic cyst of the cervical esophagus in a neonate.

Esophageal duplication cyst (EDC) is a congenital malformation of the posterior primitive foregut, which mainly occurs in the thoracic esophagus. Here, we describe a 3-year-old Han Chinese boy afflicted with intermittent fever of acute onset and dry cough. Thoracic computed tomography revealed an 10 cm × 5.4 cm × 5.8 cm oval-shaped, cyst-like tumor located in the extrapleural space, extending along the right paravertebral gutter and compressing the trachea forward. An additional small-sized, oval-shaped cyst was identified in the posterior mediastinum, between the esophagus and the spinal column, at the T1 level. During open thoracotomy, under general anesthesia, an opaque, thick-walled, esophageal cyst was revealed not to be in communication with the esophageal lumen or the trachea. This cyst was subsequently resected in an en bloc manner. The small (1-cm) esophageal cyst was left untreated based on a “wait-and-see” policy. Histological analysis showed that the resected cyst was walled by hyperplastic, fibrous tissues and locally lined with gastric mucosa inherent glands. This finding was consistent with a diagnosis of EDC, with ectopic gastric mucosa. The respiratory tract symptoms resolved immediately after the operation. Computed tomography obtained at the 6-month follow-up showed that no disease, residual or recurrence, was present after the resection of the large-sized cyst, and the small-sized cyst remained unchanged in size.

Oesophageal pseudodiverticula rarely occur after excision of benign oesophageal neoplasms. While management and outcomes have been reported in the adult leiomyoma literature, sparse data exist on the occurrence and management of pseudodiverticula after foregut duplication cyst excision. We discuss our experience with a paediatric patient and review relevant literature regarding operative techniques and surgical outcomes.

A 47-year-old man with a medical history of obstructive sleep apnea presented with five years of progressive dysphagia to solid food greater than liquids. A cyst must be attached to the esophagus and contain epithelial tissue and muscularis propria to be labeled an esophageal duplication cyst.4 There have also been reports of cysts containing ectopic alimentary tissue or presence of multiple cysts.3, 4 CT scan and endoscopic ultrasound are the investigational tests of choice.
