Annular pancreas producing duodenal obstruction: A case report
Open Journal of Gastroenterology, 2013
Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the duodenum. This malformation is usually asymptomatic in adults, but can manifests as pancreatitis, duodenal stenosis, or duodenal or gastric ulceration. We report the case of a young patient of 18 years old hospitalized for epigastric pain and vomiting, in whom radiological investigations showed an annular pancreas. At operation, a complete obstruction of the duodenum between its first and second parts was found, caused by an annular pancreas. No other congenital anomaly of the intra abdominal organs was noted. A gastroenterostomy was performed. Both the rarity of this congenital abnormality and its successful correction by surgical means have prompted us to make the following presentation.
Annular Pancreas; Delayed presentation a Case Report
IOSR Journals , 2019
Annular pancreas is a clinicopathological condition in which ectopic pancreatic tissue encircles around the duodenum and usually causes partial obstruction, but when associated with web or stenosis causes complete obstruction. These children usually present in neonatal period and infancy and straightway surgery is the treatment. Rarely presentation may be delayed as in this case who presented to us at 5 years of age with recurrent attacks of vomiting and a diagnosis of annular pancreas was made and the patient underwent duodenoduodenostomy.

Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue around the duodenum. Usually diagnosed in the neonatal period, the annular pancreas can be responsible for intestinal obstruction in 1% of cases. In adults it is asymptomatic in 50% of cases, as it can be responsible for duodenal stenosis, pancreatitis, or duodenal or gastric ulcerations. We report two cases of duodenal stenosis secondary to an annular pancreas diagnosed in two adults in whom a surgical bypass was performed allowing resolution of symptoms.

Background: Annular pancreas is one of the rarest causes of acute duodenal obstruction in neonates. The exact prevalence of annular pancreas is unclear as many individuals with annular pancreas are asymptomatic. We present a 7-day old male neonate who presented with non-bilious effortless coffee-ground vomitus from birth. He passed meconium with no subsequent motion of stool for 6days. Her radiograph showed a double bubble sign. He was diagnosed with a neonatal duodenal obstruction. Objective: To highlight the challenges in the diagnosis of neonatal duodenal obstruction. Materials and methods: The study is a case report of Annular Pancreas causing duodenal obstruction. The chart was retrieved and reviewed for the patient’s age, sex, clinical presentation, diagnosis and treatment. A search was conducted on the MEDLINE database for all applicable research; clinical reviews, retrospective studies and case reports. Results: The patient underwent duodeno-duodenostomy for an annular pancreas and the postoperative course was uneventful. Conclusion: Annular Pancreas is a rare disease in neonates causing duodenal obstruction. Imaging is supportive, but the diagnosis is confirmed by laparotomy. Duodeno-duodenostomy remains a viable operative option in neonates, Recommendation: A high index of suspicion is required by clinicians for diagnosis to avoid complications of delayed surgery.

Annular pancreas is a developmental anomaly that can be associated with other conditions such as Down syndrome, duodenal atresia, and Hirschsprung disease. A band of pancreatic tissue, in continuity with the pancreatic head, completely or incompletely encircles the descending duodenum, sometimes assuming a "crocodile jaw" configuration. We present the case of an adult who presented with epigastric pain and vomiting and was found to have annular pancreas.
Annular pancreas – a rare cause of gastric obstruction in an 82-year-old patient
Annals of The Royal College of Surgeons of England, 2005
A nnular pancreas is an uncommon and rarely reported congenital anomaly and thus is rarely suspected. The pancreas is normally formed from the fusion of the dorsal and ventral pancreatic buds between the first 4-8 weeks of embryonic life. Annular pancreas is formed due to failure of the ventral bud to rotate and elongates to encircle the early part of the duodenum. It is one of the few medical conditions which can present itself in a wide range of clinical severities and can affect neonates to the elderly, thereby making the diagnosis difficult.
Annular pancreas: a rare cause of acute pancreatitis
JOP : Journal of the pancreas, 2011
CONTEXT Annular pancreas is an uncommon and rarely reported congenital anomaly which consists of a ring of pancreatic tissue encircling the duodenum. Despite the congenital nature of the disease, clinical manifestations may ensue at any age. CASE REPORT We herein report the case of a 72-year-old female with acute pancreatitis associated with duodenal obstruction. On radiologic examination, an annular pancreas was diagnosed. In view of her previous medical history and morphologic findings, we concluded that the acute pancreatitis was directly related to the congenital anomaly. Her clinical course was favorable after medical treatment. CONCLUSION Clinicians should note the possibility of annular pancreas in patients with acute pancreatitis.
Partial Annular Pancreas- A Time Bomb?
Scholars Journal of Medical Case Reports, 2021
Annular pancreas is a rare developmental anomaly. Partial annular pancreas is less known and is very rare. A band of pancreatic tissue continues from the pancreatic head and incompletely encircles the pancreas. This typically gives a “crocodile jaw” configuration. In symptomatic cases patients present mostly in 3rd to 6th decade of their life, with abdominal pain, postprandial fullness, vomiting, upper gastrointestinal bleeding, acute or chronic pancreatitis, and in rare instances, biliary obstruction. The person can also be asymptomatic; in that case it will be an incidental finding. We are presenting a case of partial annular pancreas causing nonspecific symptoms. This was an incidental finding, studied and managed in a tertiary care centre.
A strange case of double annular pancreas
JOP : Journal of the pancreas, 2013
The pancreas is a soft lobulated gland situated transversely across the upper part of the posterior abdominal wall. Its parts include the head, neck, body and tail. Annular pancreas is a rare condition where the head of the pancreas surrounds the second part of the duodenum like a ring. We observed a rare type of double annular pancreas where the uncinate process encircled the third part of the duodenum. A process from the head of the pancreas encircled the junction between the first and second parts of the duodenum incompletely. There was a large artery running along the anterior border of the pancreas. The artery took origin from the superior mesenteric artery. This case may be of interest to gastroenterologists and surgeons.
