Can a pancreatic rest be removed?
Removal of suspected pancreatic rests with EBLSP was successful in all 21 cases without complications. Nineteen of 21 (90%) who underwent EBLSP had a histological diagnosis of heterotopic pancreas compared with 5 of 14 (36%) who underwent tissue sampling with biopsy and/or snare (P = 0.001).
What causes ectopic pancreas?
An ectopic pancreas is an anatomical abnormality in which pancreatic tissue has grown outside its normal location and without vascular or other anatomical connections to the pancreas. It is a congenital disease and is also known as heterotopic, accessory, or aberrant pancreas.
What causes pancreatic rest?
The best-known histogenic theories for the basis of pancreatic rest are based on fetal migration of pancreatic cells, followed by penetration of immature gastric mucosa inside the submucosa and subsequent differentiation into pancreatic tissue. Malignant transformation of this ectopic tissue is not common.
What is ectopic pancreatic tissue?
An ectopic pancreas is defined as pancreatic tissue lacking vascular or anatomic communication with the normal body of the pancreas. It is rarely symptomatic as it is found incidentally at laparotomy most of the time.
Is pancreatic rest common?
The pancreatic rest, is an uncommon congenital anomaly. The incidence in autopsy series varies from 1 to 2% (range 0.55 to 13%). Such tissue may occur throughout the gastrointestinal tract but has a propensity to affect the stomach and the proximal small intestine.
How do you treat a pancreatic rest?
Generally, pancreatic rests that cause no symptoms do not require treatment. However, because pancreatic rests can look similar to other submucosal nodules on imaging tests, a biopsy procedure called endoscopic ultrasound-guided fine needle aspiration, or EUS-FNA, may be recommended to rule out a cancerous growth.
What is ectopic rest?
Ectopic pancreatic tissue, also known as a pancreatic rest, is an uncommon congenital anomaly defined as extrapancreatic tissue located far from the pancreas and without any connection via vascular or anatomical means.
What is the meaning of ectopic?
Definition of ectopic : occurring in an abnormal position or in an unusual manner or form ectopic lesions.
Can pancreatic rest cause pancreatitis?
Most pancreatic rests have no symptoms, but in some cases, they can cause pancreatitis, ulcers, bleeding, or obstruction of the affected organ. Generally, pancreatic rests that cause no symptoms do not require treatment.
What is pancreatic Heterotopia?
Introduction. Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland and without vascular or ductal continuity. It is variably referred to as ectopic, aberrant, or accessory pancreas, as well as pancreatic choristoma and adenomyoma.
How rare is pancreatic rest?
How common is pancreatic rest?
Is there a malignancy in heterotopic pancreas in the duodenum?
This case report reveals the elusive nature of malignancy in heterotopic pancreas in the duodenum. Heterotopic pancreas (HP) is the presence of pancreatic tissue outside the normal anatomical boundaries, with no vascular connection with the main pancreas.
Where is a heterotopic pancreas located?
Heterotopic pancreas can exist at any position in the abdominal cavity. It is usually found in the upper gastrointestinal tract, with > 90% of the cases involving the stomach, duodenum or jejunum. Unusual locations are the colon, spleen or liver[4,5].
What is the prevalence of heterotopia in pancreatic cancer?
DISCUSSION. Pancreatic heterotopia is classically seen in the stomach, duodenum, or jejunum; 3 though cases involving the ileum, liver, gallbladder, spleen, lungs, and esophagus have been well described. 4–8 Incidental findings of pancreatic ectopia occur at a rate between 0.2% and 13% during laparotomy or autopsy.
What are the symptoms of heterotopic pancreas?
Patients with heterotopic pancreas can be normal, or present with abdominal pain and distension. In addition, it can manifest clinically in some rare diseases of the pancreas including pancreatitis, islet cell tumor, pancreatic carcinoma, and pancreatic cyst[9].
