Meta-analysis: the clinical features of the duodenal duplication cyst

Duodenal duplication cyst: a rare cause of gastro-intestinal obstruction

“…Recurrent nausea, vomiting, abdominal mass, pancreatitis, jaundice can be seen [5][6][7][8][9][10]. In the systematic review of Chen et al compiling 47 cases of DD cysts, 80% of patients presented with abdominal pain and only 18 patients were older than 20 years [1]. In some cases, ectopic gastric mucosa can appear and cause ulceration and lead to bleeding like in our case reported.…”

“…As we have said, DD cysts are mostly diagnosed in childhood and such a lesion are rarely detected in an adult like in the current case [1,2,4]. They have diverse clinical manifestations depending in the location, the presence or not of complications and the relationship with adjacent organ especially the pancreas and the biliary tree.…”

“…The definition includes a smooth-muscle coat, an alimentary epithelial lining and an intimate attachment to the GI tract. They can be cystic or tubular, communicating or not communicating [1,3,4]. Our case report has some particularities owing to its first manifestation in the adulthood, the uncommon clinical presentation with duodenal obstruction caused by endoluminal hemorrhage and the anatomical location in the antimesenteric side of the second duodenum which is very rare.…”

“…Duodenal duplications (DD) cysts are the rarest ones with less than 5% of all intestinal duplications [1,2]. The definition includes a smooth-muscle coat, an alimentary epithelial lining and an intimate attachment to the GI tract.…”

“…Intestinal duplications are mostly diagnosed in children, and less than 30% of all cases are diagnosed in adults [1,2]. Duodenal duplications (DD) are extremely rare and comprise less than 5% of all intestinal duplications.…”
