What is a duplication cyst?
Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. They may be cystic or tubular in conformation.
How do you get rid of a cyst that is duplicated?
The definitive treatment for a duplication cyst is surgery. The surgical approach can be open (laparotomy or thoracotomy) or minimally-invasive (laparoscopic or thoracoscopic) and depends on the expertise of the surgeon. Symptomatic cases: Early surgery is recommended in all the symptomatic cases.
What is an esophageal duplication cyst?
Esophageal duplication cysts are rare inherited lesions usually diagnosed in early childhood. Most of them are found in the mediastinum and manifest themselves as separate masses along or in continuity with the native esophagus. Their prevalence remains unknown and they are treated either surgically or endoscopically.
Can a cyst duplicate?
Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts.
Can you have a benign tumor in your esophagus?
Sometimes a tumor develops in your esophagus that is not cancerous (benign). The most common type—representing about 70 percent of benign tumors—is leiomyoma, which forms in the muscle. Doctors do not know what causes benign esophageal tumors. When these tumors are small, you may not have any symptoms.
Are all esophageal tumors cancerous?
Noncancerous (benign) tumors of the esophagus (the tube that connects the throat to the stomach) are rare. Some tumors can cause problems with swallowing and, rarely, ulcers, bleeding, or both. They are usually more bothersome than harmful.
What is a foregut duplication cyst?
Background: Foregut duplications are rare entities that include both esophageal and bronchogenic cysts. The diagnosis of foregut duplication cyst is made most often from an incidental finding on chest radiograph, or due to respiratory compromise due to mass effect or infection. Treatment consists of complete resection.
Where are the cystic lesions on the ureter?
Multiple cystic lesions were seen along the right ureter up to the PUJ. They were on the lateral wall as well as the anterior and posterior wall of the ureter. One of the lesions was punctured and a cloudy fluid drained out of the cyst ( Fig. 2 ). Figure 2. Ureteroscopic appearance of ureteritis cystica.
When does an ureterocele arise from a duplicate kidney?
When ureteroceles arise from the upper pole of a duplicated kidney, the upper pole is frequently dysplastic. Antenatally, ureteral duplication is commonly suggested by hydronephrosis when the upper-pole ureter is associated with obstruction or when the lower pole is associated with high-grade reflux.
What is the incidence of ureteral ectopia and duplication?
In studies of young children with UTIs, the incidence of duplication rises to 8%. The incidence of ureteroceles has been reported to be in the range of 1 per 5000-12,000 population. Approximately 10% are bilateral, 60-80% are ectopic, and 80% are associated with an upper-pole ureter of a duplex kidney.
When does hydronephrosis lead to ureteral duplication?
Age-related demographics. Antenatally, ureteral duplication is commonly suggested by hydronephrosis when the upper-pole ureter is associated with obstruction or when the lower pole is associated with high-grade reflux. The duplication may present in early childhood or later in life, when UTI prompts evaluation.
