1

Most common site for unqualified intestinal obstruction

Small bowel

2

Second most common site for unqualified intestinal obstruction

Left side of the colon

3

Most common cause of obstruction

Post-operative adhesions

4

Second most common cause of obstruction

Hernia

5

Most common cause of intraluminal obstruction

Tumor

6

Intraluminal obstruction may also be caused by constrictions
Part of the stomach sliding up to the esophageal hiatus due to intra-abdominal pressure and a negative thoracic pressure

Hiatal hernia

7

Caused by a defect in the mesentery segments of the bowel, insinuating itself into the different false internal areas

Volvulus

8

Fecal material may be lodged in the weakened colonic wall causing _____

Diverticulitis

9

Congenital problem
Failure of de-rotation, the stomach and duodenum pulls the cecum through adhesive band, preventing it from going to the proper place and causing obstruction

Malrotation

10

Single bubble sign in chest x-ray

Hypertrophied pyloric ring

11

Segment of the bowel telescopes into another segment

Intussusception

12

Clinical condition of GIT where normal transmission is impeded so that products of digestion are prevented from exiting.
Urgent management is needed

Intestinal obstruction

13

Adhesion is proximal to the ligament of Treitz, there is ____

No abdominal distention

14

If the IO is distal to the D2 segment of the duodenum, there is ____ vomitus

Bilious

15

If the IO is proximal to the D2 segment of the duodenum, it is _____

Nonbilious

16

Most common conditions of mechanical IO

Adhesions
Malignancy
Hernia

17

Etiologies can range from derangement of sympathetic and parasympathetic control of the GIT, surgical trauma, and electrolyte imbalance

Functional IO

18

Distention of colon due to obstruction usually caused by defect in sympathetic nerve supply

Ogilvie's syndrome

19

What type of loop obstructions are surgical emergencies

Closed loop

20

Distal tumor blocking and a competent ileocecal valve

Closed loop

21

Proximal bowel dilatation alters the:

GI motility

23

Most important reference in terms of level of obstruction

Ligament of Treitz

Melena is black, sticky stool associated with bleeding in ____
Bezoar
Hyponatremia and hypochloremia

Proximal upper gut

25

Succus entericus
Fecaloid if obstruction is distal
Tenderness due to marked distention
Hypokalemia and hyponatremia

Distal lower gut

26

Dx of IO

Air fluid levels
Ileus
Endoscopy (intraluminal obstruction)

27

Associated conditions of IO

Dehydration, electrolyte, malnutrition and sepsis

28

Sequelae of IO

Necrosis
