Colorectal Nursing & Stoma Care

Colorectal Anatomy

Colon Segments

Segment	Location / Notes
Caecum	Right iliac fossa; ileocaecal valve; appendix attached
Ascending colon	Right side; hepatic flexure at liver
Transverse colon	Crosses abdomen; splenic flexure on left
Descending colon	Left side; narrower lumen
Sigmoid colon	S-shaped; left iliac fossa; commonest site of diverticula & cancer
Rectum	12–15 cm; three valves of Houston; no mesentery
Anal canal	4 cm; dentate line separates columnar/squamous epithelium

Bowel Function & Blood Supply

The colon absorbs water and electrolytes (90% of water absorbed in right colon). Vascular supply: superior mesenteric artery (caecum to splenic flexure), inferior mesenteric artery (descending, sigmoid, upper rectum). Venous drainage via portal system — relevant to hepatic metastases in colorectal cancer.

Layers of the Bowel Wall (TNM staging basis)

Mucosa (T1) → Submucosa (T1) → Muscularis propria (T2) → Pericolorectal tissue (T3) → Adjacent organs (T4)

Common Colorectal Conditions

Colorectal Cancer — Most Common GI Malignancy

Dukes' Classification (historical)

Stage	Description	5-yr Survival
A	Confined to bowel wall	~90%
B	Through bowel wall, nodes clear	~65%
C	Lymph node involvement	~30%
D	Distant metastases	<10%

TNM Staging (current standard)

T1–T4: depth of tumour invasion
N0–N2: regional lymph node spread
M0/M1: absence/presence of metastasis
Stage I = T1-2N0M0 → Stage IV = any T, any N, M1

Right-Sided vs Left-Sided Tumour Differences

Feature	Right-sided	Left-sided
Presentation	Anaemia, weight loss, mass — insidious	Obstruction, rectal bleeding, change in bowel habit
Stool	Liquid — no obstruction early	Formed — obstructs easily
Molecular	MSI-H, BRAF mutation common	Chromosomal instability, KRAS
Prognosis	Historically worse	Relatively better stage-for-stage

⚠GCC Note: Rising incidence in Gulf countries — younger age of onset, linked to dietary transition (high fat, low fibre, processed foods), low-fibre traditional diet changes, sedentary lifestyle, obesity.

Diverticular Disease

Diverticulosis vs Diverticulitis

Diverticulosis: presence of diverticula (pouches) — usually asymptomatic; sigmoid commonest site
Diverticulitis: inflammation/infection of diverticula — LIF pain, fever, raised WBC, nausea
Complicated: abscess, peritonitis, fistula, obstruction

Hinchey Classification (perforation)

Stage	Description	Management
I	Pericolic/mesenteric abscess	IV antibiotics ± CT-guided drainage
II	Pelvic/distant abscess	CT drainage + antibiotics
III	Purulent peritonitis	Hartmann's procedure (sigmoid colostomy)
IV	Faecal peritonitis	Emergency Hartmann's / laparotomy

IBD Surgery

Ulcerative Colitis (UC) — Surgical Options

Proctocolectomy + end ileostomy: definitive cure; permanent stoma
Restorative proctocolectomy (IPAA/J-pouch): ileal pouch-anal anastomosis; avoids permanent stoma; 2-stage (defunctioning loop ileostomy then closure) or 3-stage
Subtotal colectomy + ileostomy: emergency option (toxic megacolon, perforation) — preserves rectum for future J-pouch

Crohn's Disease Surgery

Not curative — conservative bowel resection principle
Strictureplasty for strictures without resection
Ileocaecal resection (commonest site)
Defunctioning loop ileostomy for severe perianal/rectal disease

Anorectal Conditions

Rectal Prolapse

Full-thickness rectal protrusion; elderly women. Rx: perineal approach (Delorme/Altemeier) or abdominal rectopexy.

Haemorrhoids

Internal (above dentate — graded I–IV) vs external
Surgical: haemorrhoidectomy (Milligan-Morgan/Ferguson), stapled haemorrhoidopexy (PPH), rubber band ligation
Post-op: pain management, stool softeners, avoid straining

Anal Fissure

Tear in anal mucosa, distal to dentate line. Acute (<6 weeks) vs chronic. Posterior midline 90%. Severe pain at defaecation.

Management

GTN 0.2% ointment (chemical sphincterotomy) — headache SE
Diltiazem topical — less headache
Botulinum toxin injection
Lateral internal sphincterotomy (surgical gold standard) — risk: minor incontinence

Bowel Obstruction — Key Points

Large bowel: colorectal cancer (60%), volvulus, diverticular stricture
Volvulus: sigmoid (commonest in GCC/Africa) or caecal
Symptoms: absolute constipation (no flatus), abdominal distension, vomiting (late LBO)
Nx: NBM, NGT, IV fluids, urinary catheter, decompression/surgery

Stoma Types

Colostomy

Sigmoid Colostomy

Left iliac fossa (LIF)
Formed/soft stool — predictable output
Permanent: after APR for rectal cancer, Hartmann's
Irrigation possible for continence

Transverse Colostomy

Upper abdomen / RUQ or LUQ
Soft/semi-formed stool
Often loop; usually temporary (defunctioning)
Larger, bulkier — appliance challenges

End vs Loop

End: single lumen; distal bowel removed or closed (Hartmann)
Loop: two openings (proximal output, distal mucous fistula); reversible; supported by rod/bridge initially

Ileostomy

End Ileostomy (Brooke)

Right iliac fossa (RIF)
Spout — everted 25–30 mm to protect peristomal skin from liquid effluent
Following total colectomy (UC, FAP, Crohn's)
Permanent or temporary (restorative pathway)

Loop Ileostomy

Defunctioning: protects low anterior resection/J-pouch anastomosis
Reversible typically 8–12 weeks post-op

Output

Normal: 800–1,200 mL/day
High output: >1,500 mL/day — dehydration risk
Consistency: porridge-like to liquid; no formed stool

⚠Metabolic complications: Sodium depletion, magnesium deficiency, B12 malabsorption (if terminal ileum resected), fat-soluble vitamin deficiency, renal calculi (oxalate/urate).

Urostomy (Ileal Conduit)

Urinary diversion after cystectomy (bladder cancer) or pelvic exenteration
10–15 cm segment of ileum isolated; ureters implanted; proximal bowel re-anastomosed
Stoma: RIF, spout, continuous urine output
Normal urine output: 0.5–1 mL/kg/hr; minimum 30 mL/hr
Mucus in urine is normal (ileal mucosa)
Drainable urostomy bag with tap valve

Monitoring

Colour and clarity of urine
24-hr urine output
Signs of UTI: cloudy, offensive, systemic features
Night drainage bag to prevent reflux and ensure rest

Stoma Assessment

Stoma Colour Assessment

Colour	Significance	Action
● Pink/red	Healthy, well perfused mucosa	Normal — continue routine care
● Pale pink	Mild anaemia or poor perfusion	Monitor, report to medical team
● Dark red/dusky	Venous congestion or partial ischaemia	Urgent review, check appliance not too tight
● Purple/black	Ischaemia — EMERGENCY	Immediate medical review, torch test, may need return to theatre
White	Severe ischaemia / necrosis	Emergency — surgical review NOW

🚨Torch Test: In a darkened room, place a small torch against the stoma. If light transmits (red/pink glow) — viable; no light transmission — deeper ischaemia. Report immediately.

Stoma Physical Assessment Parameters

Size & Shape

Measure width and height with stoma guide/template
Oedema normal post-op — reduces over 6–8 weeks; re-measure regularly

Height (Profile)

Flush: skin level — high risk peristomal excoriation; convex appliance needed
Normal spout: 20–30 mm (ileostomy); 5–10 mm (colostomy)
Prolapsed: excess bowel protruding >5 cm
Retracted: below skin level — appliance fitting difficult; convex flange required

Mucocutaneous Junction (MCJ)

Where stoma meets peristomal skin — inspect for separation
Partial separation: manage conservatively with stoma powder + barrier
Complete separation: surgical review required

Stoma Complications

Early Complications (<30 days)

Ischaemia/necrosis: tight fascia, vascular injury — EMERGENCY
Mucocutaneous separation (MCS): tension, infection, steroid use, malnutrition
High output (ileostomy): >1500 mL/day — dehydration, electrolyte imbalance
Ileus / obstruction: adhesions, oedema
Haemorrhage: from stoma or anastomosis

Late Complications

Skin excoriation: commonest complication — faecal/urine contact with peristomal skin; improper flange fit
Parastomal hernia: bowel protrudes through fascial defect around stoma — bulge visible; manage with hernia support belt; surgical repair if symptomatic
Prolapse: loop stomas more common; manual reduction if viable; surgical if recurrent
Stenosis: narrowing of stoma — poor output, pain; dilate or revise
Stomal varices: portal hypertension (liver disease) — risk of significant bleeding from dilated peristomal veins

Peristomal Skin Assessment

Use validated tool: AIM / DET score (Discolouration, Erosion, Tissue overgrowth) or Ostomy Skin Tool (OST).

Common Skin Problems

Irritant contact dermatitis: enzyme-rich effluent; improve seal, use barrier
Allergic contact dermatitis: sensitivity to adhesive/accessories — patch test
Folliculitis: infected hair follicles — shave carefully, antifungal/antibiotic if needed
Pseudoverrucous lesions: chronic moisture exposure; improve flange fit urgently
Pyoderma gangrenosum: associated with IBD — purple painful ulcers; systemic treatment
Candidiasis: white satellite lesions; antifungal powder

Appliance Types & Selection

One-Piece vs Two-Piece Systems

Feature	One-Piece	Two-Piece
Construction	Flange and pouch integrated	Separate flange (baseplate) + pouch
Handling	Simpler — less manipulation	Pouch changed without removing flange
Skin disturbance	Every change removes adhesive	Flange left 3–4 days; pouch changed more often
Discreet	Lower profile	Slightly bulkier coupling
Best for	Simple stomas, dexterity issues, elderly	Active patients, frequent emptying, skin problems

Drainable vs Closed & Convex vs Flat

Drainable Pouch

Ileostomy and urostomy — liquid/semi-liquid output
Emptied when one-third full; clip or velcro closure
Changed every 1–3 days

Closed Pouch

Sigmoid colostomy — formed stool
Discarded when full (1–2 changes/day)
Easier, more discreet

Convex vs Flat Baseplate

Flat: standard — most patients
Soft convex: flush/retracted stoma, skin folds — provides outward pressure to improve seal
Deep/firm convex: significantly retracted stoma; use with belt for extra security

Appliance Change Procedure

Step-by-Step Appliance Change

Prepare: gather equipment (new appliance, adhesive remover wipes, warm water, soft cloths/gauze, scissors or template, disposal bag, barrier accessories). Wash hands.
Remove old appliance: support skin with one hand; peel flange from top corner using adhesive remover wipe/spray — slow, gentle. Avoid skin trauma.
Dispose: empty drainable pouch before removal; wrap used appliance in disposal bag; clinical waste.
Clean peristomal skin: warm water only (no soap unless needed — rinse fully); pat dry — must be completely dry before applying new appliance.
Assess stoma and skin: colour, size, MCJ, skin condition. Document findings.
Measure stoma: use template/guide; stoma size changes post-op. Cut flange to leave 3 mm clearance around stoma base — not too tight (ischaemia) not too loose (leakage).
Apply accessories: stoma powder if skin excoriation (pat off excess), barrier ring/paste to fill skin creases, barrier film/Cavilon to peristomal skin.
Apply appliance: warm flange in hands 30 seconds to activate adhesive; apply from bottom up; mould around stoma; hold firmly 30–60 seconds. Ensure no wrinkles.
Secure: close drainable pouch; attach belt if used. Document output, skin status, appliance type/size used.

⚠Important: Never use alcohol-based wipes directly on peristomal skin. No soaps with moisturiser — reduce adhesion. No talcum powder.

Accessories & Skin Protection

Key Accessories

Barrier rings (Eakin rings): hydrocolloid rings that mould to skin contours — fill creases, improve seal, protect skin
Stoma paste: fills skin irregularities; may contain alcohol — allow to dry 60 seconds
Stoma powder (karaya/pectin): absorbs moisture on excoriated skin; lightly dust and tap off excess
Convex inserts: add convexity to flat baseplate
Stoma belts: elastic belt attaches to pouch wings — extra security, parastomal hernia management
Deodorisers: drops in pouch, oral (charcoal, bismuth subgallate)
Filters: carbon filters in closed pouches — reduce gas build-up/odour

Skin Barrier Products

Cavilon No-Sting Barrier Film (3M): alcohol-free liquid polymer; protects intact and damaged peristomal skin; dries in 30 seconds; apply before flange
Comfeel Barrier Wipes: similar protection, skin conditioning
Stoma powder + barrier film (crusting technique): for moist excoriated skin — powder, then barrier film, repeat 2–3 layers; creates artificial skin surface for adhesion

Crusting Technique

Apply stoma powder to moist/excoriated skin
Apply barrier film over powder — seals and dries
Repeat 2–3 times for best adhesion surface

Irrigation (Sigmoid Colostomy)

Irrigation allows the patient to control output — lavage empties colon at predictable times; patient may need only a stoma cap between irrigations.

500–1000 mL warm water via irrigation sleeve
Once daily or every other day
Takes 45–60 minutes total
Not suitable: loop stoma, Crohn's, colitis, radiation damage, chemotherapy, frailty, poor dexterity
Taught by stoma nurse specialist; takes 4–6 weeks to establish

Diet, Fluids & Lifestyle

Dietary Guidance

Category	Foods
Increase output / loosen	Spicy food, fruit juice, prunes, alcohol, caffeine, leafy vegetables
Decrease output / thicken	White rice, pasta, banana, white bread, marshmallows, peanut butter, yogurt
Cause odour	Fish, eggs, onions, garlic, asparagus, cheese, beans
Reduce odour	Parsley, yogurt, buttermilk, cranberry juice
Cause wind/gas	Beans, lentils, cabbage, carbonated drinks, chewing gum, onions, broccoli
Risk of blockage (ileostomy)	Mushrooms, sweetcorn, celery, coconut, pineapple, nuts — chew well or avoid initially

Fluid Management (Ileostomy)

Minimum 2.5 L oral fluid/day to compensate losses
Oral rehydration solution (ORS) — sodium-containing drinks preferred over plain water
Avoid excessive plain water (dilutes sodium, worsens dehydration)
Signs of dehydration: dark urine, dizziness, cramps, reduced output, thirst
High output (>1500 mL/day): antidiarrhoeals (loperamide before meals), codeine phosphate, dietary thickeners; consider IV fluids + electrolyte replacement if >2000 mL/day

GCC Lifestyle Adaptations

Clothing: loose traditional dress (thobe/abaya) naturally conceals appliance; pouches available in skin-tone colours; high-waist underwear or stoma wraps available
Swimming: waterproof flanges; swim caps or stoma wraps; empty before swimming
Showering: can shower with or without appliance — with appliance is safer initially
Islamic guidance — Wudu with stoma: Majority opinion: wudu (ablution) remains valid with stoma. Patient should perform wudu, then if stoma leaks after, this does not invalidate wudu (continuous involuntary discharge — Sahib al-Uzr). Consult local scholar.
Prayer: Stoma appliance is sealed — does not invalidate prayer; clean appliance before prayer; extra seal with barrier ring advised.

Pre-operative Stoma Siting

Stoma Siting Principles

Pre-operative stoma siting by a trained stoma nurse specialist significantly reduces post-operative complications and improves quality of life.

Avoid (2 cm clearance from all):

Belt/waistline
Scars and skin folds
Bony prominences (ASIS, ribs, iliac crest)
Umbilicus (2–3 cm clearance)
Abdominal drains/fistulae sites
Radiation fields (if possible)
Areas the patient cannot see

Assessment Positions

Lying: identify flat area on rectus muscle
Sitting: check skin folds do not obscure site
Standing: confirm site remains accessible and flat
Mark with indelible ink and cover with transparent dressing (pre-op)

ⓘStandard positions: colostomy LIF, ileostomy RIF, urostomy RIF. Transverse colostomy: upper abdomen. Site within rectus abdominis muscle reduces risk of parastomal hernia.

Bowel Preparation & ERAS

Mechanical Bowel Preparation (MBP)

Selective use — evidence shows MBP alone increases anastomotic leak risk
Oral MBP: PEG solution (macrogol) or sodium phosphate — colonic lavage
Phosphate enema: left-sided rectal prep
Combined MBP + oral antibiotics (neomycin + metronidazole) — reduces SSI

ERAS Protocol Key Elements

Pre-op carbohydrate loading (CHO drinks until 2h pre-op — reduces insulin resistance)
No prolonged fasting: solids 6h, clear fluids 2h pre-op
Minimise bowel prep (case-specific)
PONV prophylaxis (dexamethasone + ondansetron)
Thoracic epidural or TAP block analgesia
Avoid opioids where possible (ileus risk)
Restrictive IV fluid strategy (avoid overload)
Early enteral nutrition within 24 hours of surgery
Early mobilisation day 1 post-op
Early catheter removal (day 1–2 if uncomplicated)
Early drain removal (no benefit beyond 24h in most colorectal cases)

Post-operative Stoma Nursing Care

Immediate Post-operative (0–48h)

Hourly stoma output monitoring — first 24 hours post-op
Record colour, consistency, amount in fluid balance chart
Ischaemia check: inspect stoma every 4 hours; torch test if concern
Initial appliance: clear, drainable pouch (allows inspection without removal)
No output expected for 24–48h (post-op ileus normal)
Ileostomy — output typically starts day 2–3
IV maintenance fluid until adequate oral intake established
Monitor U&E — particularly sodium and potassium (ileostomy losses)

🚨EMERGENCY signs: Purple/black stoma, no output by day 4–5 (obstruction), massive output (>3L), blood PR. Report immediately.

Patient Teaching Plan — 7-Step Independence Programme

Observation: Patient watches nurse perform full appliance change — explain each step, normalise stoma
Preparation: Patient assembles equipment independently; identifies all accessories
Skin care: Patient cleans and dries peristomal skin under supervision
Measuring & cutting: Patient measures stoma and cuts flange correctly
Applying accessories: Patient applies barrier ring/paste independently
Applying appliance: Patient applies full appliance — nurse provides feedback only
Independent change: Patient completes full change unsupervised; demonstrates emptying technique; troubleshooting knowledge confirmed

Typical teaching duration: 5–7 days post-op. Adjust pace for elderly, anxious, or complex patients.

Stoma Nurse Specialist Role & Discharge Criteria

Role of Stoma Nurse Specialist (CNS)

Pre-operative counselling and siting
Peri-operative and post-operative education
Appliance selection and troubleshooting
Psychosocial support (body image, sexuality, adjustment)
Community follow-up and helpline support
Liaison with MDT (dietitian, psychologist, surgeon)
Prescription management and appliance supply coordination
Patient support groups and peer support

Discharge Criteria — ALL must be met

Discharge medication reviewed (loperamide, electrolytes if ileostomy)

✓First appliance change with patient: typically day 3–5 post-op; timing depends on peristomal oedema resolution and patient readiness.

Chemotherapy for Colorectal Cancer

Key Chemotherapy Regimens

Regimen	Components	Setting
FOLFOX	Folinic acid (leucovorin) + Oxaliplatin + 5-Fluorouracil (5-FU)	Adjuvant stage III; metastatic 1st line
FOLFIRI	Folinic acid + Irinotecan + 5-FU	Metastatic 1st/2nd line
CAPOX/XELOX	Capecitabine + Oxaliplatin	Adjuvant; oral alternative to FOLFOX
Capecitabine	Oral prodrug of 5-FU	Adjuvant stage III; rectal chemoradiation
Bevacizumab	Anti-VEGF monoclonal antibody	Metastatic — added to FOLFOX/FOLFIRI
Cetuximab/Panitumumab	Anti-EGFR (RAS wild-type only)	Metastatic — RAS/RAF testing required first

Side Effects & Nursing Management

Oxaliplatin — Key SE

Peripheral sensory neuropathy: tingling, numbness hands/feet — cumulative; can be permanent at high doses; dose modification if grade 2+
Cold hypersensitivity (acute): dysaesthesia triggered by cold contact — avoid cold drinks, cold surfaces, wear gloves outdoors; do NOT drink cold liquids during/after infusion
Bone marrow suppression, nausea, fatigue

5-FU / Capecitabine — Key SE

Hand-foot syndrome (palmar-plantar erythrodysaesthesia): redness, blistering, peeling of palms/soles — Grade I–III; avoid friction, moisturise regularly, dose reduction if grade 2+
Mucositis: oral cavity — grade the severity; mouthwash regimen, pain management, nutritional support
Diarrhoea — can be severe; loperamide protocol; hydration
DPD deficiency screening — capecitabine toxicity risk

Capecitabine Oral Chemotherapy Safety

Store at room temperature; do not crush tablets
Taken with food (morning and evening, ~12h apart)
Cycle: 14 days on, 7 days off (standard)
Dose modification: hold if grade 2+ toxicity; restart at reduced dose
Patient education: missed dose — skip (do not double); report symptoms promptly
Warfarin interaction: INR monitoring essential if anticoagulated

Radiotherapy for Rectal Cancer

Pre-operative Chemoradiation (Rectal Cancer)

Indication: locally advanced rectal cancer (T3/T4, N+) — downstage before surgery
Regimen: external beam RT (45–50 Gy in 25–28 fractions over 5 weeks) + concurrent capecitabine or 5-FU
Short-course RT: 25 Gy in 5 fractions — used for resectable disease in some centres
Surgery planned 6–8 weeks post-completion (long course) or 1 week (short course)
Complete pathological response (pCR) in ~15–20% — watch-and-wait protocol consideration

Acute vs Late Radiotherapy Side Effects

	Acute (<3 months)	Late (>3 months)
Bowel	Proctitis, diarrhoea, tenesmus, urgency	Radiation enteritis, stricture, fistula, incontinence
Urinary	Frequency, dysuria, haematuria	Cystitis, stricture, incontinence
Skin	Erythema, moist desquamation, perineal soreness	Fibrosis, telangiectasia, lymphoedema
Sexual	Fatigue, discomfort	Erectile dysfunction, vaginal dryness/stenosis

Radiotherapy Nursing Care

Skin Care (Perineal/Pelvic)

Wash with lukewarm water and unperfumed soap; pat dry
Avoid friction, tight clothing, hot water bottles in field
Apply aqueous cream or prescribed barrier regularly
Moist desquamation: non-adherent dressings, moisture balance wound care (Mepitel One, Mepilex)
No talcum powder, deodorant, or metal-containing products in field

Bowel Management during RT

Low-residue diet during treatment to reduce bowel movement frequency
Loperamide for diarrhoea; rectal steroids for proctitis
Hydration maintenance
Bladder protocol: attend with comfortably full bladder (reduces dose to bowel)

MDT & Post-surgical ERAS

Colorectal MDT Composition & Post-surgical ERAS

MDT Members

Colorectal surgeon
Clinical/medical oncologist
Radiologist (staging and intervention)
Pathologist
Stoma Care CNS
Oncology nurse specialist
Dietitian
Physiotherapist
Clinical psychologist / counsellor
Palliative care team (early integration — all stages IV and symptom burden)
Pharmacist (chemotherapy safety)
Genetic counsellor (Lynch syndrome / FAP screening)

Enhanced Recovery After Surgery (ERAS)

Evidence-based pathway reduces hospital stay by 2–3 days
Day 1: mobilise with physiotherapist; sips of clear fluid post-extubation
Day 1–2: remove urinary catheter, discontinue IV fluids once tolerating oral
Day 1–2: soft diet introduction
Analgesia: epidural/TAP → transition to oral multimodal (paracetamol + NSAIDs + weak opioid if needed)
Drain removal: no evidence for prolonged drainage; remove day 1–2 if low output, clear
VTE prophylaxis: LMWH + TED stockings from day 1; continue 28 days post-op (colorectal cancer)
Target discharge: day 3–5 for elective colorectal resection

GCC-Specific Considerations

Colorectal Cancer in the GCC

Rising incidence across Saudi Arabia, UAE, Qatar, Kuwait, Bahrain, Oman
Younger age of onset compared to Western populations — screening begins earlier (age 40–45 in some GCC guidelines)
Dietary transition: high-fat, high-calorie, low-fibre diet; processed food consumption; sedentary lifestyle
Low awareness of bowel cancer symptoms — late-stage presentation common
Increasing obesity rates — independent risk factor
Lynch syndrome and hereditary colorectal cancer — familial history important; genetic testing referral
National colorectal cancer screening programmes being established (faecal immunochemical test / colonoscopy)

Stoma Care Challenges in the GCC

Limited stoma nurse specialists in some smaller GCC hospitals — training and workforce development priority
Product availability varies by country and hospital formulary
Insurance reimbursement for home appliances — patient advocacy needed
Language barriers — Arabic stoma education materials essential
Stigma surrounding stoma — cultural sensitivity in counselling
Post-discharge community stoma services less developed than UK/Europe
Patient support groups emerging — online communities and hospital-led groups

Islamic & Cultural Guidance for Stoma Patients

Wudu (Ablution) with a Stoma

Majority scholarly opinion (Hanafi, Maliki, Shafi'i, Hanbali): a person with continuous involuntary discharge (stoma output) is considered Sahib al-Uzr (person of excused condition)
Patient performs wudu once at the beginning of each prayer time
Wudu remains valid for that prayer time even if stoma discharges during wudu or salah
Recommend: empty pouch and ensure appliance is secure before wudu and prayer
Advise patient to consult their local scholar or fatwa council for personalised religious guidance

Prayer (Salah)

Sealed stoma appliance does not invalidate prayer
Keep appliance well-sealed with barrier ring before prayer
Prayer mat can be used normally
If concerned about noise/odour: use charcoal-filter pouches, take deodoriser drops

Hajj & Umrah with a Stoma

Patients can perform Hajj and Umrah with a stoma — adequate preparation is key
Carry sufficient supply of appliances (pack double the estimated need)
Ensure appliance change supplies in carry-on and checked luggage (airline rules for medical supplies)
Plan for heat — hot weather increases sweating, which can reduce adhesion; change more frequently
Hydration critical — especially for ileostomy patients (ORS sachets)
Identify hospital stoma services and pharmacies en route
Obtain letter from physician confirming medical necessity of supplies
During Tawaf/Sa'i — empty pouch before starting; plan change times around prayer schedule

Ramadan Fasting with a Stoma

Medically permitted to be exempt from fasting post-surgery or with chronic illness
Fasting changes stoma output timing and consistency — monitor closely
Ileostomy patients: high dehydration risk during fasting; medical exemption usually advised
If fasting: ensure adequate hydration during non-fasting hours; ORS at Iftar

Exam Preparation — DHA / DOH / SCFHS

High-Yield Exam Points

Stoma Emergencies

Purple/black stoma = ischaemia → emergency
No output day 4–5 = obstruction
Output >1500 mL = high output ileostomy → dehydration
Complete MCS = surgical review

Key Numbers

Ileostomy output: 800–1200 mL/day normal
High output: >1500 mL/day
Flange clearance: 3 mm around stoma
Ileostomy spout height: 25–30 mm
Urostomy minimum output: 30 mL/hr
Ileostomy fluids: >2.5 L/day

Oxaliplatin Nursing

Cold hypersensitivity — avoid cold
Cumulative peripheral neuropathy
Capecitabine → hand-foot syndrome + mucositis
5-FU → DPD deficiency risk
Bevacizumab → wound healing, hypertension, thrombosis

Practice MCQ Questions

1. A newly formed ileostomy is noted to have a purple-black discolouration on day 1 post-operatively. What is the PRIORITY nursing action?

A. Apply warm compresses to improve circulation
B. Change the appliance immediately
C. Perform a torch test and notify the surgical team immediately
D. Document the finding and reassess in 4 hours

Purple/black stoma indicates ischaemia — a surgical emergency. The torch test assesses depth of viability. Immediate medical notification is required as the patient may need to return to theatre for stoma revision. Warming or delaying assessment are inappropriate and dangerous.

2. What is the correct clearance when cutting a stoma flange/baseplate around the stoma?

A. Exactly to the stoma edge (no clearance)
B. 1 mm clearance
C. 3 mm clearance around the stoma base
D. 10 mm clearance to prevent constriction

3 mm clearance is the standard recommendation. Too tight risks ischaemia and trauma; too wide exposes peristomal skin to effluent causing excoriation — the most common stoma complication. The flange should fit closely but not constrict the stoma.

3. An ileostomy patient has a 24-hour output of 2,100 mL. Which intervention is MOST appropriate?

A. Reassure the patient this is normal for an ileostomy
B. Restrict oral fluid intake to reduce output
C. Administer IV fluids and electrolyte replacement; consider loperamide; notify medical team
D. Encourage plain water intake of 3 litres

Output >1500 mL/day is high output ileostomy. At 2100 mL, IV fluid and electrolyte replacement (sodium, magnesium) is required. Loperamide before meals slows transit. Plain water worsens sodium depletion. Medical team must be informed. Restricting fluids without replacement worsens dehydration.

4. A patient receiving FOLFOX chemotherapy reports tingling in their hands and feet that worsens in cold weather. Which drug is responsible?

A. Folinic acid
B. 5-Fluorouracil
C. Oxaliplatin
D. Bevacizumab

Oxaliplatin causes both acute cold hypersensitivity (dysaesthesia triggered by cold) and cumulative sensory peripheral neuropathy. Patients should be advised to avoid cold drinks, wear gloves outdoors, and not touch cold surfaces during and after infusion days. 5-FU causes mucositis and hand-foot syndrome; folinic acid is a modulator; bevacizumab causes vascular side effects.

5. Which classification system is used to stage the severity of diverticular perforation?

A. Hinchey classification
B. Dukes' classification
C. TNM classification
D. Breslow classification

The Hinchey classification stages diverticular perforation: Stage I (pericolic abscess), II (pelvic abscess), III (purulent peritonitis), IV (faecal peritonitis). Stages III and IV require emergency surgery (Hartmann's procedure). Dukes' and TNM are colorectal cancer staging systems. Breslow is used for melanoma.

6. When siting a stoma pre-operatively, which landmark must be avoided?

A. Centre of the rectus abdominis muscle
B. Right iliac fossa for an ileostomy
C. Bony prominences, skin folds, belt line, and scars
D. An area the patient can see clearly

Pre-op stoma siting should avoid bony prominences (ASIS, ribs), skin folds, the belt/waistline, scars, drains, and areas the patient cannot visualise. The stoma should ideally be placed within the rectus abdominis to reduce parastomal hernia risk. A/B/D describe correct or desired siting features.

7. What is the Brooke ileostomy?

A. A loop ileostomy used for defunctioning
B. An end ileostomy with an everted spout (25–30 mm) created after total colectomy
C. A continent ileostomy (Kock pouch)
D. An ileostomy sited in the left iliac fossa

The Brooke ileostomy is an end ileostomy with an everted (spouted) bowel end of 25–30 mm, sited in the right iliac fossa. The spout directs liquid effluent away from peristomal skin to protect it. It is the standard permanent ileostomy technique following total colectomy.

8. A stoma nurse assesses a retracted colostomy. Which appliance modification is MOST appropriate?

A. Switch from a one-piece to a closed pouching system
B. Increase flange clearance to 10 mm
C. Use a convex baseplate with a stoma belt
D. Apply barrier cream directly under the flange

Stoma retraction (below skin level) causes poor seal and leakage risk. A convex baseplate applies inward pressure to push the stoma outward, improving the seal. Adding a stoma belt provides extra security. Increasing clearance worsens leakage. Barrier cream under the flange reduces adhesion.

9. Which surgical procedure is typically performed in an emergency for Hinchey Stage III/IV diverticular perforation?

A. Primary anastomosis with defunctioning ileostomy
B. Hartmann's procedure (sigmoid resection + end colostomy)
C. Laparoscopic right hemicolectomy
D. CT-guided abscess drainage and antibiotics

Hartmann's procedure — sigmoid resection with end colostomy and closure of the rectal stump — is the standard emergency operation for Hinchey III/IV faecal or purulent peritonitis. Primary anastomosis carries high leak risk in peritonitis. CT drainage is appropriate for Hinchey I/II. Right hemicolectomy is for right-sided pathology.

10. According to Islamic jurisprudence, which ruling applies to a Muslim patient with a stoma regarding wudu?

A. The patient is permanently exempt from all forms of prayer
B. The patient must perform wudu before every prayer regardless of output
C. The patient is considered Sahib al-Uzr and performs wudu once per prayer time; discharge does not invalidate wudu during that time
D. The patient must use tayammum (dry ablution) exclusively

The majority Islamic jurisprudence opinion holds that a person with continuous involuntary discharge (stoma) is a Sahib al-Uzr (person of valid excuse). They perform wudu at the start of each prayer time, and the wudu remains valid for that time even if discharge occurs. Nurses should be aware of this to support patients' spiritual wellbeing and advise them to seek guidance from their scholar.
