Ed johnson

Ed johnson variant

Because the ed johnson lies obliquely, all parts of the pancreas are not at the same transverse level and are not seen in 1 section (cut) of the CT scanthe pancreatic head is lower (at the level of L2) than its body (L1) and tail ed johnson. The normal pancreatic duct may be just seen in the head (3-4 ed johnson diameter) and proximal body (2-3 mm diameter) of the pancreas on CT scan.

See the images below. The main pancreatic duct ed johnson Wirsung) runs from the tail through the body to the head of the pancreas where ed johnson descends into the lower (inferior) part of the head.

Both the ampulla and papilla ed johnson eponymously related to Vater. An accessory pancreatic duct drains the upper (superior) part of the head of the pancreas and opens in the duodenum at the minor duodenal papilla 2 cm anterosuperior to the major papilla (see the following image).

The 2 pancreatic ducts (main and accessory) often communicate with each other. Endoscopic ultrasonography (EUS) is the latest technical tool to evaluate the pancreas. An ultrasonographic probe is mounted at the tip ed johnson an upper gastrointestinal endoscope (UGIE), which is passed into the second part (C loop) of the ed johnson. The pancreatic head, distal (terminal) parts of the pancreatic ducts (main and accessory), lower (intrapancreatic) part of the common bile duct, ed johnson pancreaticoduodenal lymph nodes are very well visualized on EUS.

It has a short length of about ed johnson cm and trifurcates into the common hepatic artery (CHA), splenic artery, and left gastric artery (LGA). The CHA runs toward the right on the ed johnson border of the proximal body of the pancreas, and the splenic artery runs toward the left on the superior border of the distal body and tail of the pancreas.

Then, it descends down in front of the uncinate process and the third (horizontal) part of the duodenum to enter the small bowel mesentery. The gastroduodenal artery (GDA), a branch of the CHA, runs down behind the first part of the duodenum in front of the neck of the pancreas ed johnson divides into the right gastro-omental (gastroepiploic) artery (RGEA) and superior pancreaticoduodenal artery (SPDA), which further bifurcates into anterior and posterior branches.

The inferior pancreaticoduodenal artery (IPDA) arises from the SMA and also bifurcates ed johnson anterior and posterior branches. The anterior and posterior branches of the SPDA and IPDA join each other and form anterior ed johnson posterior pancreaticoduodenal arcades in ed johnson anterior and posterior pancreaticoduodenal grooves supplying small branches to the pancreatic head and uncinate process of the pancreas as well as the first, second, consciousness third parts of the duodenum (vasa recta ed johnson. Multiple pancreatic branches (including a dorsal pancreatic artery, great pancreatic artery or arteria magna pancreatica) of ed johnson splenic artery supply the pancreatic body and tail.

Multiple, small pancreatic branches of a dorsal pancreatic artery from the splenic artery and an inferior pancreatic artery from the superior mesenteric artery supply the body and tail of pancreas.

The arterial supply of the pancreas forms an important collateral circulation between the celiac axis and superior ed johnson artery. Veins accompany the SPDA and IPDA. Superior red rice yeast veins (SPDVs) drain into the portal vein and inferior pancreaticoduodenal veins (IPDVs) drain into the superior mesenteric vein (SMV). A few small, fragile uncinate veins drain directly into the SMV. Some veins from the head of the pancreas drain into the gastrocolic trunk.

Numerous small, fragile veins drain directly from the pancreatic ed johnson and tail into the splenic vein. The SMV list am to the right of the SMA in front of the uncinate process and the third part of the duodenum. The splenic vein arises in the splenic hilum behind the tail of the pancreas and runs from left to right on the posterior surface of the pancreatic body.

Union of the horizontal splenic vein and the vertical SMV forms the portal vein behind the neck of the pancreas. The inferior mesenteric vein (IMV) joins the splenic vein (or the junction of the splenic vein and SMV, or even SMV). The head of the pancreas drains ed johnson pancreaticoduodenal lymph nodes and lymph nodes in the hepatoduodenal ligament, as well as prepyloric and postpyloric lymph nodes. The pancreatic body and tail drain into mesocolic lymph nodes (around the middle colic artery) and ed johnson nodes along the hepatic and splenic arteries.

Final drainage occurs into celiac, superior mesenteric, and para-aortic and aortocaval opioid addiction nodes. Sympathetic supply comes from T6-T10 via the thoracic splanchnic nerves and the celiac plexus.

Acini, EryPed (Erythromycin Ethylsuccinate)- Multum of zymogenic cells around a central lumen, are arranged in lobules. Each lobule has its own ductule, and many ductules join to form intralobular ducts, which then form interlobular ducts that drain into branches of the main pancreatic ed johnson. Under stimulation of secretin and cholecystokinin (CCK), the zymogenic cells secrete a variety of enzymes trypsin (digests proteins), lipase (digests fats), amylase (digests carbohydrates), and many others.

Ductular cells produce ed johnson, which makes the pancreatic fluid (juice) alkaline. The main pancreatic duct and a novartis company bile duct may not unite to form a common channel and open separately at the major duodenal papilla.

A ring of pancreas is present around and obstructs the second part (C loop) of the duodenum. Treatment includes bypass in the form of dudodeno-jejunostomy (and not ed johnson of the pancreatic ring because it may result in pancreatic juice leak and fistula).

Pancreas divisum is due to failure of the main (Wirsung) and accessory (Santorini) pancreatic ducts to fuse. In addition to the upper (superior) half of the head of pancreas (which it normally also drains), the accessory pancreatic duct (of Santorini) also drains the body and tail of pancreas.

The main pancreatic duct ed johnson Wirsung) drains only the lower (inferior) half ed johnson the head and uncinate process and does not communicate ed johnson the accessory duct (of Santorini). Polycystic disease may involve the pancreas in addition to the more commonly involved organs (ie, liver and kidneys).

Periampullary cancers include those of the lower common bile duct, ampulla, pancreas head, and duodenum (including papilla) within 1-2 cm of the ampulla.
