Intrapancreatic Duodenal Duplication Cyst as a Cause of Chronic Pancreatitis in a Child

Duodenal Duplication Cysts in Children: Clinical Features and Current Treatment Choices

“…In the remaining 12 cases, the location of the duplication was variable. Seven were within the pancreas: 5 in the pancreatic head [5, 14, 21, 39, 44], 1 in the aberrant lobe connected with the main pancreatic lobe [45] and 1 in the pancreatic tail [37]. In 5 cases, the duplication cysts were not found within the pancreas.…”

“…Forty patients underwent surgical treatment of the cyst, including 21 surgical resections, 18 surgical marsupializations, 4 cholecystectomy and 1 pancreaticoduodenectomy. Five patients were successfully treated by endoscopic marsupialization [6, 15, 21, 23]. No patients received medical therapy alone.…”

“…In the case of ectopic gastric mucosa (up to 20% of cases) there could be intracystic hemorrhage or perforation of the cyst with GI bleeding and peritonitis [14, 19, 20, 44]. Intraluminal cysts are difficult to differentiate from choledochoceles (type III choledochal cyst) [17, 21]. Differential diagnosis is only possible on pathological examination, since the duodenal duplication cyst is covered both inside and out with duodenal mucosa containing a distinct layer of smooth muscle.…”

Recurrent pancreatitis due to an intraluminal duodenal diverticulum: report of a case

“…The forceps marks the lumen of the intraduodenal diverticulum (white arrow). The big black arrow points to the original lumen of the distal part of the duodenum stenosis of the duodenum account for the majority of congenital anomalies, duplication cysts or an intraluminal duodenal diverticulum (IDD) are rarely reported [3,4]. Eventually, pancreatitis is singularly reported as a sequela of these malformations [4][5][6].…”

“…The patients present with clinical signs and symptoms of intermittent duodenal obstruction (40%), gastrointestinal bleeding due to ulceration (25%) or with recurrent pancreatitis (20%). Foreign body impaction, diverticulitis and recurrent intussusception are rarely reported events [3,4,6,7,12]. A history of early satiety or intermittent postprandial abdominal pain and vomiting could be explained by distension of the diverticulum with food, leading to partial obstruction of the true lumen of the duodenum [13].…”
