15. A flat area of skin - for adequate adhesion of appliance.
The patient should be able to see the stoma.
Skin creases, folds, previous scars, Umbilicus, and
bony prominences should be avoided.
The stoma site should not be located at the beltline.
The site should be identified with the patient lying,
sitting, and standing.
Preexisting disabilities should be taken into account.
16. Ileostomies – right iliac fossa
Sigmoid colostomy – left iliac fossa
Transverse colostomy – right/left upper quadrant
18. Midline vertical incision
Adequate blood supply on either side (skin & bowel)
Without tension
Avoid pre-existing infection
Avoid too small hole at fascial level
No twist
Stoma hole at the end of the surgery.
19. Circular skin – excise adequate ( 2.5 cm diameter)

potential ischemic necrosis due to massive
dilatation
25.
26.
27. Malecot/ Mushroom catheter placed in the caecum
Advantage
Less chance of prolapse
Disadvantage

fixation of colon to the abdominal wall
extra-peritoneal tunneling of colon – difficult for
reversal & revision.
35. This vogue has passed
Still has place In colo-rectal trauma
After resection of damaged colon
Proximal & distal ends colon tracked together along
anti-mesenteric surfaces with interrupted
absorbable sutures
Easier to close
36. After total procto-colectomy
Distal end of the ileum is prefered
(save length, future ileal pouch)
Right iliac fossa
Aim – 2.5 cm spout
Mesenteric surface oriented superiorly
Ease until 5cm of ileum protrude above the skin
Superior 2 sutures – 5cm serosal bite from end
Inferior 1 suture – 4cm serosal bite from end
Series of interrupted absorbable sutures
Everted spout directed downwards
37.
38.
39. To rest the distal bowel/ to protect an anastomosis
Distal ileal loop preferred
Similar to loop colostomy
Proximal limb – lower position
Marking suture to identify proximal limb
Supporting rod may be used
Ante-mesenteric 80% circumferential incision – distal limb
Proximal limb everted
Muco-cutaneous sutures
40.
41. ileum and its supporting mesentery are grossly
thickened and the surgeon is encountering difficulty
in preparing a sufficient length of well-vascularized
ileum for a conventional end ileostomy.
ileum is prepared as in a conventional end ileostomy,
but the vascular arcades are left undisturbed.
stapled closed end of the ileum lies just within the
abdominal cavity.
Ileostomy constructed same as conventional loop
ileostomy.
42. Bringing out two cut ends at different sites
Proximal end – ileum
Distal end – ileum/ colon – mucous fistula
can be included in the abdominal wound
Advantage
Completely defunctions the bowel without the risk of
intra-abdominal leakage from a closed distal stump.
Disadvantage
difficult to close - necessitates reopening of the main
incision.
44. Intestinal reservoir for feces was first described by
Nil Kock – 1967
Originally described – U shaped pouch will interrupt
co-ordinated perisstalisis and would enhance the
capacity
Since then J, S shaped pouches have been used with
similar results.
45. Has been used as an alternative to conventional ileostomy
Selected patients ( ileo-anal anastomosis – alternative)
Ulcerative colitis
Familial polyposis
Malfunctioning ileostomy
Poorly located ileostomy
Severe injury to the peri-stomal skin – allergic reaction to
ostomy appliance
Contraindication
Crohn’s disease (recurrence)
53. Constructed intestinal segment with well-maintained
vascularity, connected to urinary tract to allow
egress of urine through stoma
Indications
After removal of urinary bladder - invasive cancer
Severe obstructive uropathy
Severe neurogenic bladder (spinal cord injury)
Congenital abnormalities
spina bifida
bladder exstrophy
54.
55. Leaking appliance – common
improper construction – flush stoma
spigot configuration is best
Radiation skin breakdown – relocation
Stone formation in the conduit
Crystal formation around the stoma
good hygiene
acidification – with venigar
Recent advances
Kock’s continent urinary diversion
56. End ostomy Loop ostomy
Vascular compromize
More chances of stomal necrosis
Easy to fix stoma appliance
Leak rate less
Reversal is difficult
Good vascularity
Less chances of stomal necrosis
Difficult to fix
Leak rate more than end
Easy to reverse
57. Loop Ileostomy
At least 12 weeks
to settle edema inflammatory adhesions
Peri-stomal skin incision 2 mm from the muco-
cutaneous junction
Sharp dissection – divide adhesions
Excise rim of skin
end-to –end anastomosis
Loop colostomy
Same as loop ileostomy closure
58.
59. Complication rate in life time
Colostomy – 25%
End-ileostomy – 57%
Loop-ileostomy – 75%
Cumulative complication at 20 yrs for ileostomy
Ulcerative colitis – 76%
Crohn’s disease – 56%
Many complications can be successfully managed with
proper entero-stomal care
Surgical correction is often unsatisfactory
60. Skin – Excoriation, Ulceration
Ischemia
Obstruction
Retraction
Para-stomal Hernia
Prolapse
Fistula
Stenosis
Other - Bleeding, perforation, Cancer
61. Mild ischemia – common – resolve in few days
Satisfactory healing depends on blood supply
Loop ostomies has better healing rate than end ostomies
Recommended
Prepare relevant bowel segment for the stoma before end of
the operation – asses blood supply at the end
Patchy necrosis confined to the mucosa – heal by secondary
intension
Complete necrosis of ileostomy – urgent revision
Short segment colostomy with necrosis – no necessity to
revise, heal with stenosis, fistula will form.
62. consequence of postoperative ischemia
Mild stenosis - simple dilatation – if effluent is liquid
Substantial stenosis – sub-acute obstruction – revision
63. Common – loop colostomy
Loop colostomies usually assiated with a degree of
para-stomal hernia
Usual complaint
difficulty in fitting the appliance/ leakage
Best option – close the stoma
Another option – devide loop – convert to end stoma
distal segment return in to abdome
Proximal – amputate prolapse
High recurrence rate
65. Commom in ileostomy
Causes
1.Leak – poor adhesion between serosal surfaces of
everted stoma
2.Para-stomal hernia
If retracted stoma is mobile
Series of non-cutting linear staplling
Avoid mesentary
If retracted stoma is immobile - laparotomy
66.
67. Formation of an abdominal stoma necessarily involves
creating a defect in the abdominal wall to
accommodate the emerging bowel. Such defects
may become enlarged as a result of tangential force
applied to the edge of the opening, and this
enlargement may lead to hernia formation
Intra abdominal pressure
Obesity
Emergency procedure – large opening
Optimal – incision which admit 2 fingers
68. Clinically
Unsightly bulge at stoma site
Leakage around the stoma appliance
Skin rahes
Difficulty in irrigation
Obstruction/strangulation
72. Full thickness bite through the bowel while froming
stoma
Pressure necrosis – tightly fitting appliance
Recurrent disease – Crohn’s disease
Treatment
laparotomy - reformation of stoma at new site
75. devastating news to a patient
sites should be marked preoperatively.
They should be on flat skin, away from scars and
avoiding bony prominences and the umbilicus. The
positioning of the patients clothing should also be
taken into account.
76.
77. Appendix is used to create a conduit between the
skin surface and the urinary bladder
Indication
Urethral cancer
Neurogenic bladder
Spinal cord injuries
Spina bifida
78.
79. Continent ileostomy (Kock pouch) is an alternative
to end ileostomy for patients who have undergone
total proctocolectomy. The procedure reached its
height of popularity in the late 1960s and early
1970s, but has been supplanted by restorative
proctocolectomy, an operation that preserves the
natural route of defecation. Continent ileostomy is
still appropriate for selected patients with
ulcerative colitis and familial polyposis who are not
candidates for restorative proctocolectomy, for
whom restorative proctocolectomy or end
ileostomy have failed, and in a few other selected
cases. Complication rates have decreased during
the past three decades following technical
80.
81. connecting the appendix to the abdominal wall and fashioning a valve mechanism
that allows catheterization of the appendix.
Indication
Fecal incontinence
