• A stoma (or ostomy, these 2 words
mean the same thing)
is a surgically created opening on the
abdomen which allows stool or urine to
exit the body.
There are 3 main types of stoma –
colostomy, ileostomy and urostomy.
When a urinary stoma is created, the urine does not go
to the bladder. The urine is rerouted through an
opening on the abdomen (stoma) created by a surgeon.
An opening in the bladder created to connect the bladder to an
opening on the lower abdomen.
The ureter (or ureters) is attached to the skin’s surface through
a small opening in the abdomen.
A small section of the ileum (small intestine) is used to create a
passage for the urine to exit the body. This section of the small
intestine, called a conduit, is attached to the abdominal wall to
create a stoma. The urine flows from the kidneys, through the
ureters, and out the stoma
• A colostomy is an artificial opening made in
the large bowel to divert faeces and flatus to
the exterior, where it can be collected in an
Depending on the purpose for which the
diversion has been necessary, a colostomy
may be :
1) temporary or 2) permanent
Types of colostomy:
• Loop colostomy: This type of colostomy is usually used in
emergencies and is a temporary and large stoma.
A loop of the bowel is pulled out onto the abdomen and held in place
with an external device. The bowel is then sutured to the abdomen
and two openings are created in the one stoma: one for stool and the
other for mucus.
• End colostomy: A stoma is created from one end of the
bowel. The other portion of the bowel is either removed or sewn shut
• Double barrel colostomy: The bowel is severed and both
ends are brought out onto the abdomen. Only the proximal stoma is
Some common reasons are:
• A section of the colon has been removed, e.g. due
to colon cancer requiring a total mesorectal
excision, diverticulitis, injury, etc., so that it is no
longer possible for feces to exit via the anus.
• A portion of the colon (or large intestine) has been
operated upon and needs to be 'rested' until it is
healed. In this case, the colostomy is often temporary
and is usually reversed at a later date, leaving the
patient with a small scar in place of the stoma.
Children undergoing surgery for extensive pelvic
tumors commonly are given a colostomy in
preparation for surgery to remove the tumor, followed
by reversal of the colostomy.

• A sigmoid colostomy is usually
brought out at the Lt. iliac fossa.
• A Transverse colostomy is usually
brought out in the Rt.
• # GA is important since since traction on the mesentery
causes pain and nausea.
• # A transverse incision 8-10cm long, with removal of a
disc of skin, is made for transverse colon (in the Rt. upper
abdomen midway between the umbilicus and
xiphisternum over the rectus abdominus muscle and
extending laterally to the lateral border of the rectus
muscle), while for the sigmoid colon (in the Lt. iliac fossa
with a muscle cutting incision).
• # Cut down all layers including the rectus muscle which is
divided transversely ligating and dividing the epigastric
• # The most proximal loop of colon is prepared by removing the
omentum from its anterior surface (only in Transverse colon), then a
small hole is made in the mesocolon through which a rubber tube is
passed to fascilitate delivery of the colon through the incision.
• # The laparotomy wound should be closed at this stage.
• # The colonic loop is held by an underlying glass rod or by a
colostomy bar or skin bridge incised initially. The colon is then
opened on its antimescolic border longitudinally (along the taenia
• # Sutures are used to fix the colonic serosa to the abdominal wall,
and colonic mucosa to the surrounding skin.
• # The finished loop colostomy should allow one finger to pass down
on each side.
2- Double Barrelled colostomy:
the colon is divided so that both ends can
be brought separately to the surface with
a skin bridge intervening.
• Advantage: ensures that the distal
segment (colon, rectum) is completely
defunctioned (Absolute Rest).
3- Hartmann’s Procedure:
• This includes a proximal End Colostomy
with a distal closed colonic segment.
• This procedure can be used when resecting
a tumour of the Lt. site of the colon or in
Complicated diverticular disease.
Complications of colostomies
• The following complications can occur to any colostomy but are
• more common after poor technique or siting of the stoma:
3) necrosis of the distal end;
4) fistula formation;
5) stenosis of the orifice;
6) colostomy hernia;
7) bleeding (usually from granulomas
around the margin of the colostomy);
8 )colostomy „diarrhoea‟: this is usually an
infective enteritis and will respond to oral
metronidazole 200 mg three times daily.
9) Many of these complications require
revision of the colostomy.
• Candidiasis= Yeast Related Infection
• Folliculitis= hair trauma
• Irritant Dermatitis= Inflammation of
the skin around the stoma
It is an artificial opening made between
the ileum and skin of the abdominal
wall, to divert intestinal contents to the
exterior, without a sphincter to control
the timing of its emptying.
Effluent is usually liquid.

How to Properly Site a Stoma*
1. Examine abdomen with patient clothed
2. Examine exposed abdomen with patient
supine, standing, sitting, bending over
3. Identify skin creases, folds, skin
problems, scars, bony prominences
4. Draw imaginary line where incision will be
5. Choose point 5 cm away from incision
with 5-7 cm of flat surface.
6. Identify and mark edge of rectus muscle
8. Mark site with X
Choose an area
visible to patient,
but below level of
9. Examine mark with
10. Mark and cover
in skin fold
Appropriate lengths for stoma
– Total bowel length
above skin = 6-8 cm
– Loop = 3 cm at
– Height of spout after
creation > 20 mm
– Total bowel length
above skin 2-4 cm
– Height of stoma after
be > 5mm

Obesity and Stoma Creation
• Increased depth of skin creases causes
pouching difficulties, even in properly
constructed, well located ostomies
• Difficult to identify the rectus muscles
• Obese patients cannot see their lower
• Thicker abdominal wall adipose tissue
requires increased amount of length of
Preoperative planning, operative
education are of vital importance
Make every stoma as though it
were going to be permanent

• In obese patients Supraumbilical
placement of stomas is desirable
• Improved Pouching
• Decreased skin irritation
• Thinner abdominal wall
