Acute symptoms due to a huge duplication cyst ruptured into the esophagus

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.

Tubular duplication of the oesophagus presenting with dysphagia

Duplications of the alimentary tract are rare congenital malformations, with the ileum being the most commonly affected site, followed by the oesophagus. Among oesophageal duplications, cystic duplication is the most common and the tubular variety, the rarest. Herein, we report a rare case of tubular oesophageal duplication, complicated by adenosquamous carcinoma at the lower end of the oesophagus, in a 32-year-old man who presented with progressive dysphagia. Although proton pump inhibitors may relieve dysphagia, oesophagectomy and gastric interpositioning should be the first-line treatment for patients with tubular oesophageal duplication, in order to reduce the risk of malignant transformation at the lower end of the oesophagus.

Acute ruptured esophageal duplication cyst

A 32-year-old man presented acutely with a ruptured esophageal duplication cyst. This is a rare complication from an unusual congenital condition. The case describes his clinical presentation, radiological investigation and surgical management. The pathology of the excised specimen is described and a literature review concludes that complete surgical resection of an esophageal duplication is always recommended, even if the condition is asymptomatic. Conventionally this is achieved via a thoracotomy, however thoracoscopic-assisted excision may have a role.

Clinical spectrum of mediastinal cysts

OBJECTIVES

Congenital cysts of the mediastinum are an uncommon but important diagnostic group, representing 12 to 30% of all mediastinal masses. The purpose of this study was to review our institutional experience with congenital cysts of the mediastinum, emphasizing the clinical spectrum of the disease.

DESIGN

Retrospective study.

OBJECTIVES

University hospital unit of general thoracic surgery.

METHODS

We retrospectively reviewed the records of 105 patients with cysts of the mediastinum (50 male and 55 female patients) who comprised 13.0% of mediastinal masses over the past 50 years.

RESULTS

There were 10 pediatric patients (< 15 years old) and 95 adult patients. The prevalence of cysts in the adult populations was higher than that in children (14.1% vs 7.7%, p < 0.05). There were 47 bronchogenic cysts, 30 thymic cysts, 12 pericardial cysts, 7 pleural cysts, 4 esophageal duplications, 2 meningoceles, 1 thoracic duct cyst, and 2 others. MRI has become a useful tool for providing supplemental data in combination with CT. Overall, 38 patients (36.2%) with mediastinal cysts were symptomatic, including 39.2% with bronchogenic/esophageal cysts, 40% with thymic cysts, and 15.8% with pericardial/pleural cysts. One hundred patients had complete resection of their masses, 3 patients with pericardial diverticulum received a thoracoscopic fenestration without mortality, and 2 patients refused surgery.

CONCLUSION

Early recognition of these relatively rare lesions would lead to immediate and appropriate surgical intervention. Early surgical intervention is also important because definitive histologic diagnosis can only be established by means of surgical extirpation.

Laparoscopic resection of intra-abdominal esophageal duplication cyst

Esophageal duplication cysts are frequently encountered in the mediastinum and rarely in the abdomen. A case of laparoscopic resection of an intra-abdominal esophageal duplication cyst is reported. An incidental 4.5 x 4.0 x 3.5-cm, well-circumscribed, homogenous mass anterior to the intra-abdominal esophagus was detected on staging CT examinations for breast cancer in a 51-year-old woman. Laparoscopic resection of the lesion was performed after completion of breast-conserving surgery and whole breast irradiation. The defect of the muscular layer of the esophagus caused by the complete removal of the lesion required repair with muscular sutures. It was helpful to inspect the integrity of the esophageal wall repair by examining the exterior wall of the esophagus laparoscopically while insufflating air into the esophageal lumen through a fiberoptic esophagoscope. A laparoscopic approach utilizing intraoperative esophagoscopy is easy and safe for removal of intra-abdominal esophageal duplication cysts.

Clinical spectrum of primary mediastinal tumors: a comparison of adult and pediatric populations at a single Japanese institution

BACKGROUND AND OBJECTIVES

The purpose of this study was to review our Japanese institutional experience of mediastinal tumors and to compare differences in the clinical spectrum between adults and children.

METHODS

We retrospectively reviewed the records of 806 patients (676 adults and 130 children) between 1951 and 2000 at our institution.

RESULTS

There were 244 thymomas (36%), 106 germ cell tumors (16%), 95 congenital cysts (14%), 82 lymphomas (12%), 76 neurogenic tumors (11%), and 24 thyroid tumors (4%) in adult patients. There were 60 neurogenic tumors (46%), 24 germ cell tumor (19%), 17 lymphoma (13%), 10 congenital cysts (8%), and 5 thymomas (4%) in the pediatric patients. There was a significant higher incidence of neurogenic tumors and a lower incidence of thymomas and thyroid tumors in children than adults. The most common location was the anterior compartment (68%) in adults and the posterior compartment in children (52%). The prevalence of malignancy in pediatric patients was lower than adults (37% vs. 47%; P < 0.05). Symptoms due to compression or direct invasion into adjacent structures may have caused the higher incidence of dyspnea or respiratory distress in the pediatric group compared to the adults (15.4% vs. 4.0%; P < 0.001). There were fewer incidences of facial edema in children compared to adults (2.6% vs. 10.7%; P < 0.02). Emergent operations were required more often in the pediatric group than the adult group.

CONCLUSIONS

We demonstrated definite differences in histologic distribution, location, and symptomatology in mediastinal tumors between adult and pediatric populations, which should be considered in the evaluation and planning of a therapeutic modality for mediastinal tumors.

Esophageal duplication cyst with esophageal web and tracheoesophageal fistula

The authors report the case of lower cervical/upper thoracic esophageal duplication associated with an obstructing esophageal web. This presented in the newborn period as an esophageal atresia. Initial resection of the web and closure of the fistula were performed. The duplication was excised electively at 2 months of age. Persistent symptomatic tracheomalacia required aortopexy, after which the child recovered uneventfully. There are only three other reports (four cases) in the literature of esophageal atresia (or variants) associated with esophageal duplication.

Diagnosis of foregut duplication cysts by endoscopic ultrasonography

BACKGROUND & AIMS

Foregut duplication cysts are rare congenital anomalies of enteric origin found most commonly in children and rarely in adults. They are usually found in adults on routine radiological studies and represent a challenging diagnostic problem. Conventional imaging tests do not lead to a conclusive diagnosis. With endoscopic ultrasonography, it is possible to distinguish between cystic and solid masses and to accurately establish the location of the cyst in relation to the gastrointestinal wall and to the mediastinum.

METHODS

Seven patients who had endoscopic ultrasonography performed because of differentiation between a cystic or solid mass lesion in the chest or abdomen could not be made with conventional radiological methods are described.

RESULTS

In all patients, a definite diagnosis was established by endoscopic ultrasonography. The diagnosis was confirmed in 2 patients after surgical excision.

CONCLUSIONS

Surgery can be avoided in patients with asymptomatic enteric duplication cysts diagnosed by endoscopic ultrasonography.

The effectiveness of transesophageal ultrasonography in preoperatively diagnosing an esophageal cyst in a 75-year-old woman: report of a case

We present herein the unusual case of a 75-year-old woman in whom an esophageal cyst was preoperatively identified with the aid of transesophageal ultrasonography. She underwent successful extirpation and has remained well since her discharge from hospital. The transesophageal ultrasonogram was shown to be a powerful diagnostic tool for the identification of a mediastinal mass located adjacent to the esophagus.

Symptomatic congenital lesions of the alimentary tract in adults

Congenital anomalies of the alimentary tract can evade detection into adulthood because they cause only moderate symptoms or they escape purview of a prepared observer. In other instances, evolution or copathogenesis may need to occur before the lesions become manifest. We have managed 17 of these patients presenting at ages 23 to 71 years. The median duration of symptoms was 5 years, ranging from 1 months to 23 years. Defects of foregut embryogenesis predominated (71%). We were able to establish the correct diagnosis before operating on nine patients, but three had already had a previous celiotomy for the same problem so a truly preoperative diagnosis was possible in only six (35%). The literature validates the dominance of foregut anomalies in adults. There is no older age limit that would exclude consideration of these lesions. Endoscopy, computerized tomography, and ultrasonography have greatly facilitated recognition, but our experience suggests that the principal obstacle to timely diagnosis is the reluctance to consider a congenital cause for an adult's symptoms.
