the stomach for drainage or feeding

Question 4

Define the following terms:
Jejunostomy
P284

Question 5

abdominal wall skin for stool drainage

Question 7

Define the following terms:
End colostomy
P284

Answer 7

Proximal end of colon brought to the skin

for stool drainage

Question 8

Define the following terms:
Mucous fistula
P284

Answer 8

Distal end of transected colon brought to
the skin for decompression; the mucosa produces
mucus, an ostomy is a fistula, and,
hence, the term mucous fistula (proximal
colon brought up as a colostomy or, if the
proximal colon is removed, an ileostomy)

Question 9

Define the following terms:
Hartmann’s pouch
P284

Answer 9

Distal end of transected colon stapled
and dropped back into the peritoneal
cavity, resulting in a blind pouch; mucus
is decompressed through the anus
(proximal colon is brought up as an end
colostomy or, if proximal colon is
removed, an end ileostomy)

Question 10

Define the following terms:
Double-barrel colostomy
P284

Answer 10

End colostomy and a mucous fistula

i.e., two barrels brought up to the skin

Question 11

Define the following terms:
Loop colostomy
P285 (picture)

Answer 11

Loop of large bowel is brought up to the
abdominal wall skin and a plastic rod is
placed underneath the loop; the colon is
then opened and sewn to the abdominal
wall skin as a colostomy

Question 12

Define the following terms:
Ileal conduit
P285

Answer 12

Loops of stapled-off ileum made into a
pouch, anastomosed to the ureters, and

to allow drainage of urine in patients
who undergo removal of the bladder
(cystectomy)

Question 13

Define the following terms:
Brooke ileostomy
P285 (picture)

Answer 13

Ileostomy folded over itself to provide

clearance from skin

Question 14

Why doesn’t an ileostomy or
colostomy close?
P286

Answer 14

Epithelialization (mucosa to skin) from

the acronym FRIEND (see page 305)

Question 15

Why doesn’t a gastrostomy
close?
P286

Answer 15

Foreign body (the plastic tube) from the
acronym FRIEND

Question 16

If the plastic tube, G-tube,
or J-tube is removed, how
fast can the hole to the
stomach or jejunum close?
P286

Answer 16

In a matter of hours! (Thus, if it comes
out inadvertently from a well-established
tract, it must be replaced immediately)

Question 17

What is a “tube check”?

P286

Answer 17

Gastrografin contrast study to confirm that
a G-tube or J-tube is within the lumen of
the stomach or jejunum, respectively
