What is pancreatic Heterotopia?
What is pancreatic Heterotopia?
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.
What is pancreatic rest in antrum?
INTRODUCTION. Pancreatic heterotopia, also known as a pancreatic rest, ectopic pancreas, myoepithelial hamartoma, and aberrant pancreas, is defined as pancreatic tissue without vascular or anatomic communication with the main body of the pancreas.
Can a pancreatic rest be cancerous?
It may remain silent over period of years or present clinically mimicking symptoms of acid peptic disease, ulcer, upper gastrointestinal tract bleeding and obstruction. Infrequently, it may lead to pancreatitis or pancreatic cancer. Radiological appearances are variable ranging from small lesion to large masses.
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.
Is pancreatic Heterotopia bad?
PH is found in approximately 5% of pancreatic or duodenal resections and is generally asymptomatic. Chronic pancreatitis is not uncommon in heterotopic pancreatic tissue, and even there is a risk of malignant transformation.
How common is pancreatic rest?
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.
Where is the antrum of the stomach?
Antrum: the lower portion (near the small intestine), where the food mixes with gastric juice. Pylorus: the last part of the stomach, which acts as a valve to control the emptying of the stomach contents into the small intestine.
What is the diet for pancreatitis?

What is Groove pancreatitis?
Groove pancreatitis is a segmental chronic pancreatitis that affects the anatomical area between the pancreatic head, the duodenum, and the common bile duct, referred to as the groove area. Most patients with groove pancreatitis are males aged 40-50 years with a history of alcohol abuse.
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.
How is an endoscopic ultrasound performed?
During EUS your doctor passes a thin, flexible tube (endoscope) through your mouth and through your digestive tract. A small ultrasound device (transducer) in the tube produces sound waves that create a precise image of surrounding tissue, including lymph nodes in the chest. The endoscope is then gradually withdrawn.
What causes erythema in the antrum?
Antrum mucosa erythematous defined means erythema, or redness, of the lining of the distal portion of the stomach. Antral mucosal erythema is commonly seen in patients with gastritis. Helicobacter pylori is a common cause for antral erythema, usually diagnosed with a biopsy taken during an endoscopy.
