16
Q

outpouchings that represent acquired herniations of mucosa and submucosa through the muscular layers at points of weakness in the bowel wall.

A

diverticulosis

17
Q

is a complication of diverticular disease of the colon (necrosing inflammation in the diverticula), especially in the sigmoid region, in which perforation of a diverticulum leads to the development of a peridiverticular abscess.

A

diverticulitis

18
Q

primarily affects young adults, cause is unknown with alternating periods of remission and relapse

A

ulcerative colitis

19
Q

patchy distribution, with involvement of multiple noncontiguous segments of colon (skip lesions)

A

crohns colitis

20
Q

characterized by the abrupt onset of lower abdominal pain and rectal bleeding.

A

ischemic colitis

21
Q

twisting of the bowel on itself that may lead to intestinal obstruction

22
Q

are varicose veins of the lower end of the rectum that cause pain, itching, and bleeding

23
Q

can develop whenever bile contains insufficient bile salts and lecithin in proportion to cholesterol to maintain the cholesterol in solution

24
Q

inflammation of the gallbladder

A

cholecystitis

25
rare condition in which the growth of gas-forming organisms in the gallbladder is facilitated by stasis and ischemia caused by cystic duct obstruction
emphysematous cholecystitis
26
calcification in the wall of the gallbladder, which forms an oval density that corresponds to the size and shape of the organ
porcelain gallbladder
27
chronic destruction of liver cells and structure, with nodular regeneration of liver parenchyma and fibrosis
cirrhosis
28
inflammatory process in which protein- and lipid-digesting enzymes become activated within the pancreas and begin to digest the organ
pancreatitis
29
loculated (walled-off) fluid collections arising from inflammation, necrosis, or hemorrhage associated with acute pancreatitis or trauma
pancreatic pseudocyst
30
Free air in the peritoneal cavity associated with significant abdominal pain and tenderness is often caused by perforation of a gas-containing viscus and indicates a surgical emergency
pneumoperitoneum
31
Enlargement of the spleen
splenomegaly
