What is the most common congenital pancreatic anomaly?

What is normal CBD diameter?
1.8mm to 5.9 mm
The normal range of CBD diameter was 1.8mm to 5.9 mm. However, 65% of the study participants had a common bile duct diameter of < 4 mm. The majority of the patients irrespective of the age group had the diameter which ranges from 2–3.9 mm. But, most subjects in the old age group had a CBD diameter ranges from 4–5.9mm.
Which duct opens in duodenum?
A single pancreatic duct opens at the junction of the transverse and ascending loops of the duodenum (see Figure 1.3B). This is the accessory pancreatic duct. The terminal part of the main pancreatic duct disappears during embryonic development. The accessory pancreatic duct communicates with both pancreatic lobes.
Can pancreatic duct dilation be normal?
A dilated pancreatic duct can arise from benign or malignant disease or can be a variant of normal in the right clinical setting. Dilated pancreatic ducts can arise from solid or cystic pancreatic tumors and, in the right setting, may warrant endoscopic evaluation and therapy, including stenting and dilation.
What are the abnormalities of pancreas?
Acute pancreatitis is a sudden attack causing inflammation of the pancreas and is usually associated with severe upper abdominal pain. The pain may be severe and last several days. Other symptoms of acute pancreatitis include nausea, vomiting, diarrhea, bloating, and fever.
Is a 3mm bile duct normal?
The common bile duct (CBD) was measured in 600 ultrasound studies. In normal patients the mean width of the CBD increased from 2.8 mm in the age group 20 years or younger to 4.1 mm in patients 71 years of age or older. The mean width of the CBD for all age groups in normal cases was 3.4 (range 2 to 11 mm).
What is rivinus duct?
The ducts of Rivinus, a group of excretory ducts, drain the sublingual gland. The largest sublingual gland excretory duct called the sublingual duct of Bartholin joins Wharton’s duct near the sublingual caruncle. The sublingual gland contributes approximately 5% of saliva in the oral cavity .
Where Hepatopancreatic duct is present in GI tract?
The hepatopancreatic ampulla, also called the hepatopancreatic duct or ampulla of Vater, is a spherical structure located at the site of the confluence of the common bile duct and pancreatic duct, marking the entry point of bile into the second portion of the duodenum.
