31
Q

Read these:

Peritonitis may result in the formation of localized abscesses (collections of purulent exudate, or pus) in various parts of the peritoneal cavity. A common site for pus to collect is in the right or left subphrenic recess or space. Subphrenic abscesses are more common on the right side because of the frequency of ruptured appendices and perforated duodenal ulcers. Because the right and left subphrenic recesses are continuous with the hepatorenal recess (the lowest [most gravity-dependent] parts of the peritoneal cavity when supine), pus from a subphrenic abscess may drain into one of the hepatorenal recesses (Fig. 5.64E), especially when patients are bedridden.

Q

Read These:

Cancer involving the pancreatic head accounts for most cases of extrahepatic obstruction of the biliary ducts. Because of the posterior relationships of the pancreas, cancer of the head often compresses and obstructs the bile duct and/or the hepatopancreatic ampulla. Obstruction of the biliary tract, usually the common bile duct or ampulla, results in the retention of bile pigments, enlargement of the gallbladder, and obstructive jaundice. Jaundice (Fr. jaune, yellow) is the yellow staining of most body tissues, skin, mucous membranes, and conjunctiva by circulating bile pigments.
