Colorectal Surgery Nursing Guide

A comprehensive perioperative and stoma care reference for nurses practising in GCC healthcare settings, aligned with DHA and SCFHS competency frameworks.

📋 6 Modules ⚙ ERAS Protocol 🏦 Stoma Care 📌 GCC Context 📅 Updated April 2026

Colorectal Anatomy

📐 Large Intestine Segments
  • Caecum – receives ileal content via ileocaecal valve
  • Ascending colon – right side; absorbs water & electrolytes
  • Transverse colon – crosses abdomen; haustra formed by taeniae coli
  • Descending colon – left side; retroperitoneal
  • Sigmoid colon – S-shaped; commonest site of diverticular disease
  • Rectum – 12–15 cm; ampulla acts as reservoir
  • Anal canal – 4 cm; internal (involuntary) & external (voluntary) sphincters
🪨 Vascular Supply (Clinical Relevance)
  • Superior mesenteric artery (SMA) – proximal to splenic flexure
  • Inferior mesenteric artery (IMA) – distal colon & upper rectum
  • Middle/inferior rectal arteries – internal iliac; distal rectum
  • Splenic flexure – watershed zone; ischaemia risk during surgery
  • Venous drainage – portal system (liver metastases route)

Common Colorectal Conditions

🔵 Colorectal Cancer

Third most common cancer globally; increasing incidence in GCC linked to dietary westernisation, obesity, and sedentary lifestyle. Mean age at presentation in GCC is ~55 years — younger than Western cohorts.

  • Change in bowel habit >4 weeks
  • Rectal bleeding (frank or occult)
  • Unexplained iron-deficiency anaemia
  • Abdominal mass / tenesmus
  • Unintentional weight loss
🟠 Diverticular Disease

Herniation of mucosa through muscular wall. Most common in sigmoid colon. Low-fibre diets prevalent in GCC populations increase risk.

  • Diverticulosis – asymptomatic pockets
  • Diverticulitis – inflammation; LIF pain, fever, leucocytosis
  • Complicated – perforation, abscess, fistula, obstruction (Hinchey classification)
  • Surgery – Hartmann's procedure or primary resection & anastomosis
🟢 Inflammatory Bowel Disease (IBD)
  • Crohn's disease – transmural; any GI segment; skip lesions; fistulae
  • Ulcerative colitis (UC) – mucosal; rectum to proximal; continuous
  • Surgery for UC: total proctocolectomy ± ileal pouch-anal anastomosis (IPAA)
  • IBD incidence rising in Arabian Gulf — likely environmental & microbiome factors
🟩 Anorectal Conditions
  • Haemorrhoids – grades I–IV; rubber band ligation, haemorrhoidectomy
  • Anal fistula – Parks classification (intersphincteric, transsphincteric, suprasphincteric, extrasphincteric); seton suture
  • Rectal prolapse – full-thickness; Delorme's / Altemeier / abdominal rectopexy
  • Pilonidal disease – higher incidence in hirsute males; GCC population susceptible

GCC Colorectal Cancer Epidemiology

🌎 Regional Burden & Risk Factors

Colorectal cancer is among the top 3 cancers in UAE, Saudi Arabia, Kuwait, and Qatar. Key regional drivers:

  • High consumption of red/processed meat
  • Low dietary fibre intake
  • Rising obesity and type 2 diabetes rates
  • Physical inactivity (climate-driven sedentary lifestyle)
  • Genetic predisposition (HNPCC, FAP families)
  • Younger age of onset vs Western populations
Late Presentation Studies across GCC show 40–60% of colorectal cancers present at Stage III or IV due to lack of screening awareness, cultural reluctance for colonoscopy, and symptom normalisation.
Expat Population The large South Asian and Southeast Asian expat workforce (40–60% of GCC population) brings different genetic risks and dietary patterns, requiring culturally tailored screening strategies.

Staging Systems

📊 TNM & Dukes Classification
StageTNMDukesDescription5-Year Survival

IVAny T Any N M1DDistant metastases (liver, lung, peritoneum)~15%

CT staging (chest/abdomen/pelvis) + MRI rectum for rectal cancers. CEA baseline for surveillance.

Pre-admission Assessment

📋 Nurse-Led Pre-operative Assessment

History & Risk Stratification

  • Comorbidities: DM, hypertension, cardiac, renal
  • Medications: anticoagulants, immunosuppressants, steroids
  • Allergies (povidone iodine, latex — common in GCC settings)
  • Nutritional status: weight loss >10%, albumin <30 g/L
  • Smoking / alcohol / Shisha use
  • BMI (obesity prevalent in GCC: UAE ~37% adult obesity)
  • Performance status (ECOG / ASA grade)

Investigations

  • FBC, U&E, LFT, coagulation, group & save
  • HbA1c, fasting glucose (DM optimisation)
  • CEA baseline
  • ECG, ECHO if indicated
  • Chest X-ray / CT chest-abdomen-pelvis
  • MRI pelvis (rectal cancer, CRM assessment)
  • Cardiopulmonary exercise testing (CPET) if high-risk

ERAS Protocol for Colorectal Surgery

Enhanced Recovery After Surgery (ERAS) Multimodal evidence-based pathway reducing complications by 30–50%, hospital stay by 2–3 days, and readmission rates. Mandated in most GCC tertiary centres.
📅 Pre-operative ERAS Elements
  • Patient education & expectation setting
  • Carbohydrate loading (400 mL CHO drink 2–3 hrs pre-op)
  • Shortened fasting: clear fluids until 2 hrs, solids until 6 hrs
  • Prehabilitation: exercise, physiotherapy, smoking cessation 4–6 wks
  • Nutritional optimisation (immunonutrition 5–7 days pre-op if malnourished)
  • VTE assessment and initiation of LMWH
  • Selective bowel preparation (per surgeon preference)
  • Stoma siting by ET nurse if applicable
  • Anxiolytic premedication (minimise opioids)
Intra-operative ERAS Elements
  • Laparoscopic / minimally invasive approach preferred
  • Goal-directed fluid therapy (avoid over/under-hydration)
  • Short-acting anaesthetic agents
  • Epidural / TAP block for open surgery
  • Normothermia (Bair Hugger, warmed fluids)
  • Avoid routine nasogastric tube
  • Minimise drain use (selective)
  • Antibiotic prophylaxis (cefuroxime + metronidazole within 60 min)

Bowel Preparation

💊 Mechanical Bowel Prep (MBP)

Historically standard; evidence now supports selective use. MBP alone is NOT recommended; combination with oral antibiotics (OABP) is preferred for colonic surgery.

  • Agents: Polyethylene glycol (PEG), sodium phosphate, sodium picosulfate
  • Nurse role: Ensure adequate hydration, monitor electrolytes (risk of hyponatraemia in elderly/renal impairment)
  • Contraindications: Obstruction, megacolon, ileus
GCC Note Patients may be fasting for Ramadan; coordinate bowel prep timing carefully with the surgical team.
💊 Oral Antibiotic Bowel Prep (OABP)

Reduces surgical site infection (SSI) by targeting intraluminal flora. Combined MBP + OABP shows best outcomes in colorectal trials (SWAMP trial, MOBILE trial).

  • Regimen example: Neomycin 1 g + metronidazole 500 mg at 2 pm, 6 pm, 10 pm the day before surgery
  • Alternative: Neomycin + erythromycin base (if metronidazole intolerance)
  • Nurse role: Confirm administration, document, counsel on GI side effects (nausea)

Stoma Siting

📌 Pre-operative Stoma Site Marking by ET Nurse

Enterostomal therapy (ET) nurse should site and mark the stoma before surgery. Optimal siting reduces complications by up to 70%.

Principles of Stoma Siting:

  • Within the rectus abdominis muscle
  • Away from bony prominences, scars, umbilicus, skin folds
  • Visible to patient (below waistline, above skin fold)
  • Marked with indelible ink + verified with pouching system
  • Assessed supine, seated, standing, bending
  • Consider clothing (thobe/abaya in GCC — waistband position)

Site by Procedure:

  • Right hemicolectomy – ileostomy: RIF (right iliac fossa)
  • Left hemicolectomy / sigmoid – colostomy: LIF (left iliac fossa)
  • Anterior resection (loop) – loop ileostomy: RIF
  • APR (Abdominoperineal resection) – end colostomy: LIF
  • Hartmann's – end colostomy: LIF

VTE Prophylaxis

💉 Venous Thromboembolism Prevention
HIGH RISK — Colorectal Cancer
  • LMWH: Enoxaparin 40 mg SC daily
  • Start 12 hrs post-op (or pre-op if no epidural)
  • Continue 28 days post-op (extended prophylaxis) for cancer patients
MECHANICAL
  • TED stockings pre-op and post-op
  • Intermittent pneumatic compression (IPC) intra-op & post-op
  • Early mobilisation — Day 0 post-op (ERAS)
NURSE MONITORING
  • Assess calf tenderness, leg swelling daily
  • Tachycardia / desaturation → Doppler / CTPA
  • Bleeding risk: surgical site, epidural space (withhold if spinal)
  • Renal impairment: adjust dose (CrCl <30 mL/min → UFH)

Nutritional Optimisation & Immunonutrition

🌿 Nutritional Assessment
  • Screen with MUST (Malnutrition Universal Screening Tool)
  • Dietitian referral if MUST score ≥2 or weight loss >10%
  • Serum albumin <30 g/L: high post-op complication risk
  • Pre-operative nutritional support 7–14 days if severely malnourished
  • Target: protein 1.2–1.5 g/kg/day pre-op
  • Post-op: oral diet from Day 0–1 (ERAS); NG feeding if unable
🧪 Immunonutrition

Oral supplements enriched with arginine, omega-3, ribonucleotides. Reduces SSI and length of stay in colorectal cancer patients.

  • Indication: Malnourished patients, major resection
  • Timing: 5–7 days pre-op (e.g., Impact Oral, Reconvan)
  • Dose: 3 cartons/day (Impact)
  • GCC availability: Available in UAE/Saudi; check formulary
  • Halal certification: Confirm for patient acceptability in GCC

Stoma Formation: Colostomy vs Ileostomy

🟢 Colostomy
  • Type: End or loop; left iliac fossa
  • Output: Formed/semi-formed stool (sigmoid); looser (transverse)
  • Volume: 200–600 mL/day
  • Appearance: Flush or slightly raised; pink/red; moist
  • Management: Closed/drainable pouch; irrigation possible for end colostomy
  • Complications: Retraction, prolapse, parastomal hernia, skin excoriation
🔵 Ileostomy
  • Type: End or loop; right iliac fossa; spout 25–30 mm above skin
  • Output: Liquid to porridge consistency
  • Volume: 800–1200 mL/day (up to 2000 mL = high output)
  • Electrolytes: High sodium loss → dehydration & AKI risk
  • Management: Drainable pouch; change every 3–5 days
  • Complications: Dehydration, renal impairment, skin excoriation (proteolytic enzymes)

Post-operative Monitoring

📊 Anastomotic Leak — Peak Risk Day 3–5
Early Warning Signs (Day 3–7) Tachycardia >100 bpm (often FIRST sign) · Pyrexia >38°C · Increasing abdominal pain · Change in drain output (turbid / faeculent) · Leucocytosis · CRP >150 mg/L on Day 3
  • NEWS2 monitoring every 4 hrs minimum
  • Monitor drain character and volume (document hourly initially)
  • CRP Day 1, 3, 5 post-op (rising trend is concerning)
  • CT abdomen/pelvis with contrast if suspicion (water-soluble contrast enema for rectal)
  • Inform surgical team IMMEDIATELY if signs develop
  • Prepare for return to theatre or IR drainage
📋 Return of Bowel Function
  • Flatus expected: Day 1–3 (laparoscopic); Day 2–4 (open)
  • Bowel movement: Day 2–4 typically
  • Stoma output: Usually Day 2–4 post-op (green/brown liquid initially)
  • NG tube: Avoid routine insertion (ERAS); use only for persistent vomiting
  • Ileus concern: Absent bowel sounds + distension + no flatus by Day 4 → review opioids, encourage mobilisation, consider prokinetics

ERAS Post-op Milestones:

  • Day 0: Fluids, sit out of bed, remove urinary catheter (laparoscopic)
  • Day 1: Mobilise, light diet, remove epidural or reduce PCA
  • Day 2–3: Regular diet, physiotherapy, discharge planning

Pain Management

💊 Epidural Analgesia
  • Preferred for open colorectal surgery (T8–T10 level)
  • Local anaesthetic ± opioid (bupivacaine + fentanyl)
  • Monitor: BP (hypotension), motor block, urinary retention, respiratory depression
  • Assess dermatomal block every 4 hrs
  • LMWH: withhold 12 hrs before insertion/removal
  • Wean Day 2–3 post-op; transition to oral analgesia
  • TAP block alternative if epidural contraindicated
💊 PCA & Multimodal Analgesia
  • IV PCA morphine/fentanyl: lockout 5–10 min; 4-hr limit
  • Paracetamol IV/oral 1 g QDS (regular, not PRN)
  • NSAIDs: diclofenac/ketorolac — use cautiously (anastomotic leak risk debated)
  • Gabapentin/pregabalin: opioid-sparing, neuropathic component
  • Sedation scoring (Richmond Agitation Sedation Scale)
  • Respiratory rate monitoring (epidural/opioid)
  • Naloxone available at bedside

Drain Management

🪱 Post-operative Drain Care
Indication
  • Pelvic drain for low anterior resection / APR
  • Abdominal drain for contaminated field
  • Not routinely used for elective colonic resection (ERAS)
Monitoring
  • Document colour: serosanguinous → serous (normal)
  • Turbid / purulent / faeculent → leak
  • Drain amylase Day 3 if doubt (leak if >3× serum amylase)
  • Volume: >200 mL/hr bright red → haemorrhage alert
Removal
  • Remove when output <50 mL clear in 24 hrs
  • Typically Day 2–4 for pelvic drain
  • Never remove if amylase elevated or output suspicious

Stoma Assessment

🔎 Stoma Assessment Parameters
Colour
  • Pink/red: Normal, well-perfused
  • Pale/dusky: Monitor; possible ischaemia
  • Black/necrotic: Emergency — surgeon stat
  • Check with torch — mucosal ischaemia may extend below skin
Size & Shape
  • Measure stoma width and height
  • Oedematous initially (swelling reduces 6–8 weeks)
  • Ileostomy: 25–35 mm spout; colostomy: near-flush
  • Re-size aperture at 6–8 weeks (shrinkage)
Output & Peristomal Skin
  • Ileostomy: liquid/porridge (800–1200 mL/day normal)
  • Colostomy: formed/semi-formed
  • No output 48 hrs → obstruction? Retraction?
  • Peristomal skin: intact, same colour as surrounding skin

Pouching Systems

🧊 One-Piece System
  • Skin barrier and pouch integrated in single unit
  • Advantages: Simple, lower profile, less expensive
  • Disadvantages: Entire system changed; more skin manipulation
  • Change frequency: Every 3–4 days (ileostomy) or 4–5 days (colostomy)
  • Best for: Patients with good dexterity; shallow stomas
🧋 Two-Piece System
  • Separate baseplate (flange) + pouch that clicks/locks on
  • Advantages: Pouch changed without removing baseplate; less skin trauma
  • Disadvantages: Bulkier; higher cost
  • Change frequency: Baseplate every 3–4 days; pouch drainable (empty when 1/3 full)
  • Best for: High-output ileostomy; frequent emptiers; elderly patients
💊 Accessories
  • Barrier rings/paste (fill convexities, protect skin)
  • Convex inserts (for flush/retracted stoma)
  • Stoma powder (weeping peristomal skin)
  • Adhesive remover wipes (gentle, no-sting)
  • Hernia support belt (parastomal hernia prevention)
  • Night drainage bag (high-output ileostomy)
Appliance Change Procedure
  1. Empty pouch before removal
  2. Remove gently using adhesive remover; support skin
  3. Wash peristomal skin with warm water only (no soap with lanolin)
  4. Dry thoroughly (pat, not rub)
  5. Measure stoma; cut aperture 2–3 mm wider than stoma
  6. Apply barrier ring/paste if indicated
  7. Warm baseplate in hands 30 seconds (improves adhesion)
  8. Apply from bottom upward; press firmly for 30–60 seconds
  9. Ensure filter is intact and clip/clip seal is secure

High-Output Ileostomy Management

High-Output Ileostomy: Output >1500 mL/day (some sources >2000 mL) Risk of severe dehydration, AKI, hypomagnesaemia, hyponatraemia. Common post-colorectal surgery. Requires active medical and nursing management.
💧 Causes & Triggers
  • Post-operative ileus resolution (large flush)
  • Short bowel syndrome
  • Infection (C. difficile, viral gastroenteritis)
  • Medications (laxatives, magnesium, antibiotics)
  • Dietary indiscretion (spicy food, very fibrous foods — common in GCC)
  • Obstruction with overflow
🧪 Management Protocol
  • IV fluid replacement (NaCl 0.9% + 20 mmol KCl per litre)
  • Restrict hypotonic fluids (water, tea, juices) — worsen output
  • Oral rehydration solution: St Mark's Hospital formula (NaCl 3.5 g, sodium bicarbonate 2.5 g, glucose 20 g in 1 L)
  • Loperamide 4 mg QDS (up to 16 mg/day); give 30–60 min before meals
  • Codeine phosphate 30–60 mg QDS (second-line)
  • Omeprazole 40 mg BD (reduces secretions)
  • Dietitian referral for food thickening & guidance
  • Daily electrolytes; renal function; magnesium supplementation if low
  • Subcutaneous octreotide if refractory (>3000 mL/day)

Patient Education Checklist

📋 Pre-Discharge Stoma Education — use checkboxes to track (saved in browser)

Islamic Perspective on Stoma — Wudu & Prayer

Supporting Muslim Patients with a Stoma
Islamic Ruling (Fatwa) Scholars including those at Dar al-Ifta (UAE, Egypt) and the Saudi Fiqh Council have ruled that patients with a stoma are permitted to perform Tayammum (dry ablution) or perform Wudu with the appliance in place. The stoma does not invalidate the purity of a Muslim patient — they can pray normally. Consult local Islamic scholar for individual guidance.
  • Reassure patient that prayer is permissible with stoma
  • Advise emptying pouch before prayer if possible
  • Recommend odour-filter pouches to maintain discretion during congregational prayer
  • Hajj / Umrah: plan supply, avoid over-exertion, carry extra supplies
  • Ramadan: consult dietitian; fluid intake in non-fasting hours; monitor electrolytes
  • Refer to Islamic Medical Association resources and hospital chaplain/imam if available

Stoma Reversal Counselling

📋 Reversal Considerations
  • Loop ileostomy reversal: typically 8–12 weeks after primary surgery when anastomosis healed
  • Hartmann's reversal: 3–6 months; high morbidity — not all patients suitable
  • Prerequisites: Anastomosis intact (gastrografin enema / MRI), nutritional status optimised, no ongoing adjuvant chemotherapy complication, patient psychologically ready
  • Counsel that reversal is a surgical procedure with its own risks
  • Post-reversal: loose stools, urgency, incontinence initially (LAR syndrome possible)
  • Pelvic floor physiotherapy pre-reversal
  • Some patients choose to retain stoma — normalise this decision
  • Document patient's wishes regarding reversal from pre-op stage

Major Complications

🔴 Anastomotic Leak
Critical Complication — 3–10% incidence; up to 30% mortality if delayed recognition
  • Timing: Peak Day 3–7 (can occur Day 1–14)
  • Signs: Tachycardia (earliest), fever >38.5°C, abdominal pain/peritonism, faeculent drain, elevated CRP, leucocytosis, clinical deterioration
  • Investigation: CT abdomen/pelvis with IV contrast (water-soluble contrast enema for rectal anastomosis)
  • Grade A: Radiological only; conservative management (nil by mouth, antibiotics, drain)
  • Grade B: Clinical; IR drainage ± defunctioning stoma
  • Grade C: Return to theatre; Hartmann's procedure
  • Nursing: NEWS2 escalation, IV access, bloods, surgeon notification immediately
🟢 Paralytic Ileus
  • Definition: Functional non-mechanical bowel obstruction; inhibited peristalsis
  • Duration: Prolonged ileus >3 days (laparoscopic), >5 days (open) is clinically significant
  • Signs: Abdominal distension, nausea/vomiting, no flatus/stool, high-pitched or absent bowel sounds
  • Causes: Excess opioids, hypokalemia, hypomagnesaemia, peritonitis, immobility

Management:

  • Review and reduce opioids; add laxatives
  • Correct electrolytes (K⁺ >4.0 mmol/L; Mg²⁺ >0.8 mmol/L)
  • Mobilise aggressively; chewing gum (vagal stimulation)
  • NG tube if vomiting/distension (decompression)
  • IV fluids; maintain hydration
  • Exclude mechanical obstruction: CT if no improvement by Day 5
💉 DVT / Pulmonary Embolism
Colorectal cancer patients are HIGHEST risk group for VTE
  • DVT signs: Calf tenderness, swelling, erythema, pitting oedema; may be asymptomatic
  • PE signs: Tachycardia, pleuritic chest pain, dyspnoea, haemoptysis, hypoxia, syncope
  • Investigation: Doppler USS (DVT); CTPA (PE); D-dimer (if low clinical probability)
  • Treatment: LMWH therapeutic dose → oral anticoagulation (DOAC or warfarin) 3–6 months; consider 6+ months in cancer
📌 Wound Dehiscence
  • Superficial: Skin breakdown; secondary healing with dressings
  • Deep (fascial dehiscence): Burst abdomen — EMERGENCY
  • Signs of burst abdomen: Sudden serosanguinous soaking of dressing ("salmon-pink" discharge) with sense of "giving way"; bowel visible
  • Risk factors: Obesity, DM, malnutrition, steroids, wound infection, coughing
  • Nursing action: Cover bowel with warm moist sterile towels; nil by mouth; IV access; call surgeon immediately; theatre

Stoma Complications

ComplicationDefinition / SignsTimingManagement
RetractionStoma retracts below skin level; concave appearance; leakage riskEarly or lateConvex baseplate; barrier rings; ET nurse review; surgical revision if severe
ProlapseStoma protrudes >6 cm; oedematous; can be reducible or fixedWeeks–monthsManual reduction (lubrication, cool compression); surgical revision if incarcerated/necrotic
StenosisNarrowing of stoma opening; ribbon stool; obstruction symptomsMonths–yearsDigital dilation; surgical revision (revision often needed)
Parastomal herniaBowel protrusion through abdominal wall around stoma; bulge around stomaMonths–years (up to 50% of colostomies)Support belt; surgical repair (mesh); resiting of stoma
Skin excoriationPeristomal skin breakdown from effluent contact (especially ileostomy enzymes)Any timeBetter fit; barrier products; stoma powder; antifungal if candida present
NecrosisBlack/dusky colour; loss of viabilityFirst 24–72 hrsImmediate surgical review; torchlight assessment; may need revision

Low Anterior Resection Syndrome (LARS)

🔴 LARS — Impact on Quality of Life

Cluster of bowel dysfunction symptoms occurring after low anterior resection. Affects 60–80% of patients to varying degrees. Can significantly impair quality of life and return to work.

Symptoms:

  • Urgency and frequency (multiple bowel movements per day)
  • Clustering (several BMs in a short period)
  • Incontinence (flatus or faeces)
  • Incomplete evacuation / tenesmus
  • Constipation alternating with diarrhoea

Assessment & Management:

  • LARS Score questionnaire (validated tool, 5 questions; score 0–42)
  • No LARS: 0–20; Minor: 21–29; Major: 30–42
  • Pelvic floor physiotherapy (first-line)
  • Dietary modification (low-FODMAP; avoid gas-forming foods)
  • Loperamide for diarrhoea; laxatives for constipation
  • Transanal irrigation (TAI) for major LARS
  • Sacral nerve stimulation (refractory cases)
  • Reassure: symptoms improve 12–18 months post-op

Genetic Counselling Referral

🧬 HNPCC / Lynch Syndrome

Hereditary Non-Polyposis Colorectal Cancer (HNPCC) — Lynch syndrome. Autosomal dominant; MLH1, MSH2, MSH6, PMS2 gene mutations. Accounts for ~3% of CRC but proportionally higher in younger GCC patients.

Amsterdam II Criteria (refer if 3 or more):

  • 3 relatives with Lynch-associated cancer (CRC, endometrial, small bowel, ureter)
  • 2 successive generations affected
  • 1 relative diagnosed before age 50
  • FAP excluded
🧬 FAP — Familial Adenomatous Polyposis

APC gene mutation; autosomal dominant. Hundreds to thousands of colonic polyps from adolescence. Near 100% lifetime CRC risk if untreated.

  • Prophylactic colectomy advised by age 25 (or when polyps dense)
  • Annual sigmoidoscopy from age 12–14
  • Upper GI surveillance (duodenal/gastric polyps)
  • Genetic testing of first-degree relatives
  • Desmoid tumours: NSAID chemoprevention (sulindac)
  • GCC genetic centres: KFSH Riyadh, Cleveland Clinic Abu Dhabi, HMC Qatar

Dietary Advice for GCC Patients

🌿 Halal High-Fibre Diet Guidance

Encourage:

  • Whole grains: whole wheat bread, brown rice, barley (shai & hareesa alternatives)
  • Legumes: lentils (adas), chickpeas (hummus), fava beans (ful medames)
  • Vegetables: okra (bamia), zucchini, spinach, carrots — well-tolerated by new stoma
  • Fruits: dates (moderate), figs, apples, pears (peeled initially)
  • Fish: 2–3 servings/week (omega-3 protective)
  • Adequate hydration: 2–3 L/day (especially ileostomy)

Limit / Avoid (especially post-stoma formation):

  • Processed meats (sausages, deli meats — even halal brands)
  • Excessive red meat (>3 portions/week)
  • Spicy foods (increase stoma output)
  • Nuts and seeds (initially — obstruction risk)
  • Carbonated drinks (gas formation)
  • Onions, garlic, leeks (odour/gas via stoma)
Cultural Note Traditional Khaleeji foods (harees, thareed, machboos) can be adapted. Work with dietitian and patient family to create culturally appropriate high-fibre meal plans.

Ramadan Adaptations for Stoma Patients

Supporting Stoma Patients During Ramadan
Religious Guidance Islamic scholars and bodies including the Islamic Organization for Medical Sciences (IOMS, Kuwait) have issued rulings that stoma patients may be exempt from fasting (Rukhsa) given the medical need for continuous nutrition and hydration — especially high-output ileostomy patients. Patients should seek personal fatwa from a trusted scholar.
  • Consult surgeon/dietitian before deciding to fast
  • Ileostomy patients: high risk of dehydration — generally advised NOT to fast without medical clearance
  • Colostomy patients: may fast safely if output is controlled and electrolytes stable

Practical Nursing Advice:

  • Schedule stoma appliance change at iftar or suhoor (easier around mealtimes)
  • Encourage suhoor high-fibre meal to slow GI transit
  • Fluid repletion: 2–3 L between iftar and suhoor for ileostomy
  • Monitor for dehydration, AKI, electrolyte disturbance during Ramadan
  • Weigh patient twice weekly during Ramadan if fasting
  • Medications: retime drug schedules to iftar/suhoor doses with pharmacist review
  • Post-op Ramadan: no fasting for ≥6 weeks post colorectal surgery regardless of stoma type
