ILEOSTOMY AND COLOSTOMY

ANATOMY / DIVERSION / CARE

2

From anatomy to the ward round

We begin with the bowel and the reasons for diversion. Then we follow the patient through stoma care, complication recognition and the possibility of reversal.

01

Define and classify

Identify the bowel segment, construction and intended duration of a stoma.

02

Explain the choice

Relate ileostomy and colostomy to the operation, distal bowel and expected output.

03

Understand care

Explain site selection, pouching, skin protection and fluid monitoring.

04

Recognise complications

Distinguish problems needing stoma care from those needing urgent surgical assessment.

Slide 3: The bowel itself is brought to the skin

A THE BOWEL OPENING

Ileostomy: bowel route and mucosal opening. NIDDK, NIH

B THE COLLECTION APPLIANCE

Collection pouch

Bowel mucosa

Skin barrier

Abdominal wall

A bowel opening. Bowel is brought to the abdominal surface so intestinal contents can leave through it. Its visible surface is bowel mucosa; the pouch is the appliance that collects the output.

A different route for stool and gas. An intestinal stoma does not have the voluntary control of the anal sphincter.

Stoma = bowel opening. Pouch = collection appliance.

Ileostomy

Colostomy

Front view · blue arrow: output Retained downstream bowel is shown pale.

Ileostomy

The opening is made from ileum: output leaves before reaching the colon.

Colostomy

The opening is made from colon: the amount of colon upstream influences stool consistency.

The downstream bowel

It may remain in place and be bypassed, or may have been removed as part of the operation.

The name identifies the bowel segment, not the operation that preceded it.

Bowel segment. Ileostomy or colostomy.

Construction. End, loop or divided ends brought to the surface.

Intended duration. Temporary or permanent; reversal depends on anatomy, recovery and fitness.

“End” does not mean “permanent”. “Loop” does not guarantee reversal.

Why create a stoma?

I · THE PURPOSE OF DIVERSION

ILEOSTOMY AND COLOSTOMY

ANATOMY / DIVERSION / CARE

6

01

Divert

Keep the faecal stream away from a distal anastomosis, wound or diseased segment.

02

Avoid an unsafe anastomosis

After resection, exteriorise bowel when joining it immediately is unsafe or impossible.

03

Relieve obstruction

Provide an outlet when the obstructing lesion cannot be resected at that operation.

04

Provide lasting evacuation

When the anus or sphincter mechanism has been removed or cannot function adequately.

The indication determines the operation and the type of diversion.

Slide 7: Temporary and permanent stomas

Temporary and permanent stomas

I · DURATION IS AN INTENTION

ILEOSTOMY AND COLOSTOMY

ANATOMY / DIVERSION / CARE

7

LATER CONTINUITY MAY BE POSSIBLE

Temporary intention

A later operation may restore bowel continuity after the original problem has resolved.

LONG-TERM STOMA IS PLANNED

Permanent intention

Long-term evacuation through the stoma is planned when a usable distal outlet is absent or unsuitable.

Intention is not a promise. Complications, disease progression or reduced fitness can prevent a planned reversal.

Counselling must explain both the intended plan and the possibility that it changes.

An intact loop reaches the surface

The loop is opened and matured so proximal and distal lumens lie beside one another.

Proximal lumen

Receives intestinal contents from upstream and supplies the main output.

Distal lumen

Leads to the bowel being diverted; mucus may still be produced downstream.

P = proximal D = distal

Two adjacent lumens are parts of the same loop of bowel.

THE ILEAL ROUTE

Ileostomy · NIDDK, NIH

The same bowel segment can serve different operative plans.

Temporary diversion

Selected low colorectal or coloanal anastomoses and ileal pouch surgery.

After colectomy without anastomosis

An end ileostomy provides an outlet while the distal bowel is managed separately.

After proctocolectomy

An end ileostomy can provide permanent evacuation when no pouch reconstruction is planned.

Restoration of continuity is considered when healing and the overall clinical situation permit it.

A diverting stoma does not make an anastomosis immune to complications.

SURFACE VIEW

SIDE CUTAWAY

Open lumen

Terminal ileum is exteriorised

The bowel end is brought through the abdominal wall without twist or undue tension.

An everted spout

The bowel is turned outward and fixed to skin so effluent enters the pouch away from the skin.

Remaining bowel determines options

A retained rectum and a removed rectum lead to different reconstruction possibilities.

AFTER SURGERY

WITH ADAPTATION

ON THE WARD

1

Early output can be liquid

The colon is bypassed or absent, so water and salt losses require attention.

2

Output may thicken with adaptation

Consistency changes after surgery; the trend and the patient’s hydration both matter.

3

Record volume, not only pouch emptying

Measure 24-hour output and assess intake, urine, electrolytes and renal function.

A functioning stoma can still cause clinically important dehydration.

After distal colorectal resection

An end colostomy may be required when a distal anastomosis is unsafe or impossible.

Distal obstruction or disease

Diversion may relieve obstruction or allow treatment of distal pathology.

Removal of the anal outlet

Abdominoperineal excision requires a permanent colostomy.

Alternative colonic levels

More proximal colon

Less colon remains upstream for water absorption; output can be looser.

Descending or sigmoid colon

More colon remains in circuit, so output is generally more formed.

Site is a clue

Abdominal position alone does not prove the bowel segment or the operative anatomy.

Not every colostomy produces formed stool.

ILEOSTOMY AND COLOSTOMY

ANATOMY / DIVERSION / CARE

01

Anatomy

Which healthy bowel can reach the marked site with preserved blood supply and no undue tension?

02

Purpose

Which segment must be bypassed, and is partial diversion enough?

03

Patient factors

Hydration risk, body habitus, ability to manage an appliance and future reconstruction matter.

The choice is individual; one stoma type is not correct for every patient.

III · PREPARING THE PATIENT

ILEOSTOMY AND COLOSTOMY

ANATOMY / DIVERSION / CARE

23

Understanding before surgery

The planned operation, the appliance and life at home belong in the same conversation.

01

Explain the reason. Why diversion is needed and how it fits into the planned operation.

02

Explain the practical change. Output passes into an appliance; the patient needs teaching in emptying, changing and skin care.

03

Discuss duration honestly. Temporary intention, possible later reconstruction and reasons reversal may not happen.

04

Involve the stoma care team. Address body image, daily life, support at home and access to supplies.

ABDOMINAL SURFACE · FRONT VIEW

Rectus abdominis

Possible site

The mark is individual—not a fixed quadrant.

Visible and reachable

A flat, usable skin surface

Avoid scars, deep creases, the belt line and bony prominences.

Within rectus abdominis

Select an abdominal wall route appropriate for the bowel and abdominal contour.

Assess different positions

Inspect lying, sitting and standing before marking the site.

The best site on an operating table may be a poor site when the patient sits up.

BARRIER FIT · SURFACE VIEW

Close-fitting aperture

Exposed skin

The opening protects skin without constricting bowel.

Inspect at each change

Look for leakage, redness, erosion, rash or trauma.

Fit the barrier closely

Expose as little surrounding skin as possible without constricting the stoma.

Correct the cause

Leakage and poor fit need correction; skin products alone do not solve a failed seal.

Seek specialist help

A stoma nurse can adjust the appliance and assess persistent skin problems.

Peristomal skin should remain intact and comfortable.

THE CONSEQUENCE IS WATER AND SALT LOSS

Water + sodium

Interpret output alongside intake, urine and renal function.

Clinical meaning

Output high enough to cause water and salt depletion.

A useful warning level

Bailey & Love links persistent output above 1.5 L/day with dehydration and sodium depletion without intravenous replacement.

Interpret the whole balance

Risk depends on intake, urine, losses and renal function; lower output can still be unsafe for an individual patient.

A volume threshold supports assessment; it does not replace assessment.

Record amount and change over time

Symptoms and blood tests complete the assessment.

Symptoms

Thirst, dry mouth, dizziness, fatigue or muscle cramps.

Urine

Reduced volume and a darker colour are warning signs.

Assessment

Measure intake and stoma losses; check electrolytes and renal function.

Escalation

Unwell patients or those unable to maintain hydration need prompt clinical assessment.

01

Restore fluid and electrolyte balance

Assess severity; provide intravenous replacement when clinically required.

02

Use a supervised fluid plan

A prescribed oral rehydration solution may be needed; excessive plain water can worsen losses in high output.

03

Reduce losses and review causes

Review reversible causes; prescribed antimotility or antisecretory treatment may help. Pain, distension or vomiting needs surgical assessment.

Fluid restriction or medication requires a clinical plan, not unsupervised self-treatment.
