Ch. 3 Abdomen - Pathology Flashcards
the twisting of a loop of intestine, which creates an obstruction
volvulus
chronic disease involving inflammation of the colon that occurs primarily in young adults and most frequently involves the rectosigmoid region
ulcerative colitis
abnormal accumulation of fluid in the peritoneal cavity
ascites
complete or nearly complete blockage of the flow of intestinal contents
dynamic/mechanical bowel obstruction
chronic inflammation of the intestinal wall that results in bowel obstruction in at least half of affected patients
Crohn’s disease
(regional enteritis)
the telescoping of a section of bowel into another loop, which creates an obstruction
intussusception
free air or gas in the peritoneal cavity
pneumoperitoneum
two most common sites of intestinal involvement of Crohn’s disease
terminal ileum and proximal colon
most common site involved in ulcerative colitis
rectosigmoid region
ileus most frequently caused by peritonitis
adynamic ileus
characterized by loops of small intestine joined by fistulas or connected openings with adjacent loops of intestine
Crohn’s disease
extreme dilation of segment of colon
toxic megacolon
nonmechanical bowel obstruction which can be either adynamic or paralytic; inability of the intestine to contract normally and move waste
ileus
where is intussusception most common and in who
distal small intestine (termina ileum) and more common in children
ileus caused by lack of intestinal motility
paralytic (paralysis) ileus
