Gastroenterology Nursing Guide

Abdominal Assessment

Systematic Abdominal Examination

Always follow the sequence: Inspect → Auscultate → Percuss → Palpate (auscultation before percussion/palpation avoids altering bowel sounds).

Inspection

Distension: generalised (ascites, obstruction, ileus) or localised (hernia, mass); ask patient to cough to reveal hernias
Visible peristalsis: suggests bowel obstruction or pyloric stenosis; rippling movement from left to right
Scars & stomas: note location — midline laparotomy, RIF (appendectomy/ileostomy), LIF (colostomy), RUQ (cholecystectomy)
Hernias: umbilical, inguinal (reducible/irreducible), femoral (higher incarceration risk), incisional
Skin changes: caput medusae (portal hypertension), Grey Turner's sign (flank bruising — haemorrhagic pancreatitis), Cullen's sign (peri-umbilical bruising)
Other: abdominal striae, dilated veins, visible pulsation (aortic aneurysm)

Auscultation

Present (normal): 5–34 sounds per minute; gurgling, clicking
Absent: no sounds after 2 minutes — paralytic ileus, peritonitis, post-anaesthesia
Hyperactive: loud, high-pitched, frequent — early obstruction, gastroenteritis, post-meal
Borborygmi: prolonged loud gurgling; hunger or early obstruction
Bruit: systolic bruit over aorta/renal arteries — vascular disease; listen before palpation

Percussion

Tympanic (resonant): normal gas-filled bowel; hyperresonant over distended bowel
Dull: fluid (ascites — shifting dullness, fluid thrill), solid organ, mass
Liver span: percuss from right nipple downward — normal 6–12 cm
Splenic dullness: Traube's space (left 6th–10th rib, anterior axillary line) — dullness suggests splenomegaly

Palpation

Light palpation first: assess for guarding, tenderness, superficial masses; watch patient's face
Deep palpation: organomegaly, deep masses
Rebound tenderness (Blumberg): pain worse on release than pressure — peritonism; gentle test
Guarding: involuntary rigidity — peritoneal irritation; "board-like" rigidity in perforation
Murphy's sign: press under right costal margin; ask patient to inhale — acute cholecystitis causes inspiratory arrest (positive)
McBurney's point: 1/3 of the way from ASIS to umbilicus (RIF) — tenderness indicates appendicitis
Rovsing's sign: pressure in LIF causes pain in RIF — positive in appendicitis
Psoas sign: pain on right hip extension — retrocaecal appendicitis
Obturator sign: pain on internal rotation of flexed right hip — pelvic appendicitis

Stool Assessment

Bristol Stool Chart & Colour Assessment

Type	Description	Clinical Significance
Type 1	Separate hard lumps	Severe constipation
Type 2	Lumpy sausage	Mild constipation
Type 3	Sausage with cracks	Normal
Type 4	Smooth, soft sausage	Ideal stool
Type 5	Soft blobs, defined edges	Lacking fibre
Type 6	Fluffy pieces, mushy	Mild diarrhoea
Type 7	Entirely liquid	Severe diarrhoea

Stool Colour

Colour	Cause	Action
Black/tarry (melaena)	Upper GI bleed (>100 mL) — digested blood	Urgent — endoscopy
Bright red (haematochezia)	Lower GI bleed — haemorrhoids, colitis, malignancy	Assess volume; colonoscopy
Pale/clay/white	Biliary obstruction — absence of bilirubin in stool	LFTs, ultrasound
Silver/putty	Ampullary cancer (melaena + pale stool combined)	Urgent GI referral
Dark green	Bile salts — malabsorption, rapid transit	Investigate if persistent
Red — food related	Beetroot, red food dye	Dietary history first

Pain Assessment

SOCRATES Pain Assessment & Organ Correlation

SOCRATES Framework

Site — where exactly? Point with one finger
Onset — sudden (perforation, vascular) vs gradual (inflammatory)?
Character — colicky (obstruction, renal colic), burning (GORD/PUD), constant dull (inflammation)
Radiation — shoulder tip (diaphragmatic irritation), back (pancreatitis/AAA), loin to groin (ureteric colic)
Associations — nausea, vomiting, fever, change in bowels
Time course — constant vs intermittent; hours/days/weeks
Exacerbating/relieving — food, posture, movement, defaecation
Severity — 0–10 VAS/NRS scale

Location to Organ Correlation

Region	Likely Organs	Key Conditions

Loin/flank	Kidneys, ureters, psoas	Renal colic, pyelonephritis, psoas abscess

Common GI Investigations

GI Investigations Reference

Endoscopic

OGD (upper endoscopy): oesophagus, stomach, duodenum — 6 h fast; diagnoses PUD, oesophagitis, varices, malignancy
Colonoscopy: entire colon + terminal ileum — bowel prep required; diagnoses CRC, IBD, polyps
Flexible sigmoidoscopy: rectum to splenic flexure; no full prep needed
ERCP: biliary & pancreatic ducts — diagnosis + therapeutic (stone extraction, stenting)

Stool Tests

Faecal calprotectin: elevated in IBD (>200 mcg/g); helps differentiate IBD from IBS
H. pylori stool antigen: active infection; use 2 weeks off PPIs for accuracy
C. difficile toxin: if recent antibiotics + diarrhoea
Faecal occult blood (FOB): CRC screening

Imaging

AXR: bowel obstruction (dilated loops, air-fluid levels), free air under diaphragm (perforation)
Ultrasound abdomen: gallstones, liver lesions, ascites, biliary dilation; no radiation
CT abdomen/pelvis: gold standard for acute abdomen; CT pneumocolon for CRC staging
MRI abdomen: liver characterisation, MR cholangiopancreatography (MRCP) for biliary tree

Bloods

LFTs: ALT/AST (hepatocellular), ALP/GGT/bilirubin (cholestatic)
Amylase/lipase: pancreatitis (lipase more specific, stays elevated longer)
CEA, CA19-9: CRC and pancreatic cancer tumour markers
H. pylori CLO test: rapid urease test during endoscopy biopsy

Gastro-oesophageal Reflux Disease

GORD — Assessment & Management

Retrograde passage of gastric contents into the oesophagus causing symptoms or mucosal damage. Highly prevalent in GCC populations.

Clinical Features

Heartburn (retrosternal burning, worse after meals/lying flat)
Regurgitation of acid or food
Dysphagia — alarm symptom requiring urgent endoscopy
Extraoesophageal: chronic cough, laryngitis, dental erosion, asthma exacerbation

Nursing Management

Head of bed elevation 30°: raise bed head (not just pillows) to use gravity
PPI therapy: omeprazole/pantoprazole 20–40 mg once daily before breakfast; 4–8 week course for erosive oesophagitis
Antacids: Gaviscon for breakthrough symptoms; alginate layer protects oesophagus
Refer for endoscopy: alarm symptoms, age >50 with new symptoms, failed treatment

GCC-Specific Lifestyle Advice

Avoid spicy foods (chilli, hot sauces) — common in Gulf cuisines — trigger acid secretion
Reduce fatty foods (fried dishes, ghee-heavy meals) — delay gastric emptying
Limit dates & date syrup (high sugar) — can exacerbate GORD particularly in large quantities
Reduce tea & coffee — very common beverages; caffeine relaxes lower oesophageal sphincter
Avoid large evening meals — especially important during Ramadan (large Iftar may worsen nocturnal GORD)
No eating within 3 hours of lying down; weight management given high obesity prevalence
Smoking cessation — smoking reduces LOS pressure

⚠ Barrett's oesophagus (columnar metaplasia) complicates long-standing GORD and carries risk of oesophageal adenocarcinoma. Requires endoscopic surveillance every 2–5 years.

Peptic Ulcer Disease

Peptic Ulcer Disease (PUD)

Mucosal break >5 mm in stomach (gastric ulcer) or proximal duodenum (duodenal ulcer). Two main causes: H. pylori and NSAIDs/aspirin.

H. pylori Eradication — Triple Therapy

● Standard 7–14 day regimen: PPI (omeprazole 20 mg BD) + Amoxicillin 1 g BD + Clarithromycin 500 mg BD for 7–14 days. Confirm eradication with urea breath test or stool antigen 4 weeks after completion (off PPIs for 2 weeks).

Bismuth quadruple therapy used if clarithromycin resistance suspected (bismuth + PPI + metronidazole + tetracycline)
Document penicillin allergy — substitute metronidazole for amoxicillin if allergic
Encourage full course completion despite symptom improvement

NSAID-Induced Ulcers

Risk greatest with non-selective NSAIDs (ibuprofen, diclofenac, naproxen)
PPI prophylaxis co-prescribed for patients on chronic NSAIDs (especially if >65 years, previous PUD, on anticoagulants)
Consider COX-2 selective inhibitor if NSAID essential
Advise taking NSAIDs with food and plenty of water

Complications

Bleeding: most common — melaena, haematemesis, haemodynamic instability
Perforation: sudden severe epigastric pain, "peritonitic abdomen", free air on AXR/CT — surgical emergency
Gastric outlet obstruction: recurrent vomiting of undigested food, weight loss, succussion splash
Malignant transformation: gastric ulcers require biopsy; duodenal ulcers rarely malignant

Upper GI Bleed

Upper GI Bleed — Emergency Management

⚠ Call for help immediately. Secure 2 large-bore IV cannulae, send bloods urgently, monitor every 15 minutes. Upper GI bleed has up to 10% mortality.

Immediate Nursing Actions (ABCDE approach)

IV access ×2 (16G or larger) — both antecubital fossae
Bloods: FBC, U&E, LFTs, coagulation, crossmatch 4–6 units
IV fluid resuscitation: 500 mL 0.9% NaCl stat if haemodynamically unstable
Nil by mouth — anticipate urgent endoscopy
IV PPI: omeprazole 80 mg bolus then 8 mg/hr infusion (reduces rebleeding)
Urinary catheter — monitor hourly urine output (>0.5 mL/kg/hr target)
Continuous monitoring: SpO2, HR, BP, GCS, RR every 15 min
Notify senior clinician, gastroenterology, and endoscopy team
Blood transfusion: target Hb >70 g/L (80 g/L in cardiac disease); avoid over-transfusion — worsens portal hypertension

Rockford Score (Blatchford Score)

Calculated from Hb, urea, SBP, HR, presence of melaena, syncope, liver disease, cardiac failure. Score ≥1 indicates need for endoscopic intervention. Higher score = higher risk of rebleeding or death.

Sources of Upper GI Bleed

Cause	Features	Management
Peptic ulcer (most common ~40%)	Epigastric pain, NSAID/H.pylori history	Endoscopic haemostasis, PPI infusion
Oesophageal varices (~10%)	Liver disease, portal HTN signs	Terlipressin, prophylactic antibiotics, band ligation
Mallory-Weiss tear	Forceful vomiting precedes bleed	Usually self-limiting; endoscopy if severe
Oesophagitis/erosions	GORD symptoms, alcohol history	PPI, treat underlying cause
Malignancy	Weight loss, dysphagia, anaemia	Endoscopy, oncology referral

Acute Pancreatitis

Acute inflammatory process of pancreas. Most common causes: gallstones (40%) and alcohol (35%). In GCC — gallstones predominate; alcohol less common (cultural/religious). Also: hypertriglyceridaemia, ERCP, drugs, idiopathic.

Diagnosis

Severe epigastric pain radiating to back ("belt-like"), nausea, vomiting
Serum lipase >3× upper limit of normal (or amylase); lipase preferred (more specific, elevated longer)
CT abdomen (with IV contrast) — Balthazar grade; diagnoses necrosis
USS: identify gallstones (all patients), CBD dilation

Severity Scoring

Ranson Criteria (at 48 h):

Age >55, WBC >16×10⁹/L, glucose >11 mmol/L, LDH >350, AST >250 (on admission)
At 48 h: Hct fall >10%, BUN rise >1.8, Ca²⁺ <2.0, PaO₂ <8 kPa, base deficit >4, fluid sequestration >6 L
Score ≥3: severe pancreatitis

Glasgow-Imrie Score (at 48 h):

PaO₂ <8 kPa, Age >55, Neutrophils >15, Calcium <2.0, Renal (urea >16), Enzymes (LDH >600/AST >200), Albumin <32, Sugar (glucose >10)
Mnemonic: PANCREAS
Score ≥3 = severe

Nursing Management

Fluid resuscitation: aggressive IV crystalloid (Hartmann's or 0.9% NaCl) 250–500 mL/hr initially; monitor urine output (target >0.5 mL/kg/hr)
Analgesia: IV morphine or hydromorphone (IM pethidine avoided — no evidence of benefit); regular reassessment
Nil by mouth: only while nauseated and vomiting; transition to early enteral nutrition (nasojejunal if needed) within 24–48 hours — reduces infection and mortality in severe pancreatitis
NG tube: if vomiting is persistent; not routinely required
Monitor: vital signs hourly, strict fluid balance, blood glucose (may require insulin), Ca²⁺, FBC, CRP daily
ERCP: indicated within 72 hours if gallstone pancreatitis + cholangitis or persistent biliary obstruction (jaundice, rising bilirubin)
Antibiotics: only if infected necrosis suspected (fever + CT features); not routine

⚠ Complications: pancreatic necrosis (SIRS, organ failure), pseudocyst, abscess, chronic pancreatitis, exocrine/endocrine insufficiency. Severe pancreatitis (score ≥3) should be managed in HDU/ICU.

H. pylori in GCC

H. pylori — GCC Epidemiology & Management

Helicobacter pylori is a gram-negative spiral bacterium colonising gastric mucosa. GCC prevalence: approximately 20–30% in adults — lower than many Middle Eastern countries but higher than Western Europe. Transmission: faecal-oral; linked to overcrowding and shared water sources.

Diagnostic Tests

Test	Use	Notes
Urea breath test (UBT)	Active infection; post-treatment confirmation	Stop PPIs 2 weeks, antibiotics 4 weeks prior
Stool antigen test	Active infection; post-treatment (≥4 weeks after)	Monoclonal preferred; stop PPIs 2 weeks prior
Serology (IgG)	Population studies; not for post-treatment confirmation	Stays positive for years after eradication
CLO test (biopsy)	Endoscopy biopsy from antrum; rapid urease test	Most accurate during endoscopy
Histology	Gold standard; also shows gastritis, atrophy, metaplasia	2 biopsies from antrum + 2 from body

After Eradication

Confirm eradication with UBT or stool antigen 4–6 weeks post-therapy (off PPIs for ≥2 weeks)
If first-line fails — second-line: bismuth quadruple or levofloxacin-based therapy
Gastric ulcers: repeat OGD 6–8 weeks to confirm healing and exclude malignancy

Irritable Bowel Syndrome

Irritable Bowel Syndrome (IBS)

Functional GI disorder — no structural abnormality. Rome IV criteria: recurrent abdominal pain ≥1 day/week for ≥3 months, associated with ≥2 of: related to defaecation, change in stool frequency, change in stool form.

Subtypes

IBS-C Constipation-predominant — Bristol types 1–2 >25% of time
IBS-D Diarrhoea-predominant — Bristol types 6–7 >25% of time
IBS-M Mixed — both constipation and diarrhoea
IBS-U Unclassified

Red Flags (exclude before diagnosing IBS)

Age >50, rectal bleeding, unexplained weight loss, nocturnal symptoms, family history CRC/IBD, iron deficiency anaemia
Raised CRP/faecal calprotectin — suggests organic disease

Management

Dietary

Low FODMAP diet: restrict Fermentable Oligosaccharides, Disaccharides, Monosaccharides, Polyols — effective in 50–70%; requires dietitian support for reintroduction phase
Regular meals; avoid large fatty meals
Reduce gas-forming foods (beans, onions, carbonated drinks)
Soluble fibre (ispaghula husk) — preferred over insoluble bran (may worsen symptoms)

Pharmacological

Antispasmodics: mebeverine 135 mg TDS, hyoscine butylbromide (Buscopan) — for cramping/pain
Loperamide: IBS-D — reduces frequency and urgency
Osmotic laxatives: IBS-C — macrogol (polyethylene glycol)
Low-dose amitriptyline: 10–30 mg nocte — centrally acting; reduces visceral hypersensitivity
CBT/gut-directed hypnotherapy: for psychological component

Inflammatory Bowel Disease

Inflammatory Bowel Disease (IBD)

Crohn's Disease

Distribution: any part of GI tract (mouth to anus); most commonly terminal ileum + colon
Pattern: transmural inflammation, skip lesions (areas of normal bowel between diseased areas)
Endoscopy features: cobblestone mucosa, aphthous ulcers, deep fissures, strictures
Radiology: string sign on barium follow-through (strictured terminal ileum)
Complications: fistulae (enterocutaneous, perianal), abscess, strictures, bowel obstruction, malabsorption, vitamin B12/D deficiency, extra-intestinal manifestations
Symptoms: diarrhoea (non-bloody), abdominal pain (RIF), weight loss, perianal disease, malaise

Ulcerative Colitis

Distribution: rectum and extends proximally; continuous involvement (no skip lesions)
Pattern: mucosal inflammation only (not transmural)
Endoscopy features: diffuse erythema, loss of vascular pattern, friability, pseudopolyps in chronic disease
Mayo Score: stool frequency, rectal bleeding, endoscopy findings, physician assessment (0–12; ≥10 = severe)
Symptoms: bloody diarrhoea, urgency, tenesmus, mucus PR, crampy abdominal pain
Complication: toxic megacolon (emergency — avoid colonoscopy), colorectal cancer risk (after 8–10 years), PSC association

Feature	Crohn's Disease	Ulcerative Colitis
Extent	Entire GI tract	Colon only (rectum→proximal)
Depth	Transmural	Mucosal/submucosal
Pattern	Skip lesions	Continuous
Bleeding	Less common	Prominent (bloody diarrhoea)
Fistulae	Common (perianal)	Rare
Smoking	Worsens disease	Protective (?)
Surgery curative?	No (recurs)	Yes (colectomy)

IBD Treatment Ladder

Mild UC: 5-ASA (mesalazine) oral + topical rectal; sulfasalazine
Moderate UC/Crohn's: oral corticosteroids (prednisolone 40 mg tapering); azathioprine/6-MP as steroid-sparing
Severe/refractory: IV hydrocortisone in hospital; ciclosporin for acute severe UC
Biologics: anti-TNF (infliximab IV, adalimumab SC), vedolizumab (gut-selective), ustekinumab — for moderate-severe disease refractory to steroids/immunomodulators
Surgery: colectomy (curative in UC — ileal pouch-anal anastomosis "J-pouch"); resection in Crohn's for complications

⚠ Nursing considerations: Monitor for biologic side effects (infusion reactions, infections including TB reactivation). Ensure TB screening and hepatitis B serology before starting biologics. Vaccinate (avoid live vaccines on immunosuppressants).

Diverticular Disease

Diverticular Disease & Diverticulitis

Outpouchings (diverticula) of colonic mucosa through muscular wall at weak points (where vessels penetrate). Predominantly left-sided (sigmoid colon) in Western/GCC populations. Strongly linked to low-fibre diet and constipation.

Diverticulitis (Infected/Inflamed Diverticulum)

Left iliac fossa pain (steady, not colicky), fever, raised CRP/WBC, nausea
CT abdomen/pelvis is diagnostic — shows pericolic fat stranding, diverticula, complications
Hinchey classification grades perforation/abscess severity

Management

Uncomplicated (Hinchey I–II): antibiotics (co-amoxiclav 625 mg TDS PO or IV if severe), analgesia, clear fluids → soft diet as tolerated; most resolve conservatively
Complicated (abscess): CT-guided drainage, IV antibiotics
Perforation/peritonitis (Hinchey III–IV): emergency surgery (Hartmann's procedure — sigmoid colectomy + end colostomy)
Preventive: high-fibre diet, adequate hydration — patients often need education on fibre sources in GCC diet

Colorectal Cancer

Colorectal Cancer (CRC)

Rising incidence in GCC — linked to adoption of westernised diet (high fat, low fibre, processed food), obesity, T2DM, physical inactivity. Now among top 5 cancers in many Gulf states.

Symptoms (2-Week Wait Referral)

Change in bowel habit (>6 weeks) — looser/more frequent stools
Rectal bleeding (without obvious benign cause in >40 years)
Unexplained weight loss, fatigue (iron deficiency anaemia)
Palpable abdominal or rectal mass
Bowel obstruction (acute presentation)

Staging — TNM

Stage	Description	5-year Survival
I	Confined to bowel wall (T1-T2 N0 M0)	~90%
II	Through bowel wall, no nodes (T3-T4 N0 M0)	~70-80%
III	Regional lymph node involvement (any T N1-2 M0)	~50-70%
IV	Distant metastasis (any T any N M1)	~10-15%

MDT Management

Surgery: right/left hemicolectomy, anterior resection, abdomino-perineal resection (low rectal) — may result in stoma
Neoadjuvant radiotherapy: rectal cancer — downstage before surgery
Adjuvant chemotherapy: CAPOX or FOLFOX — stage III and high-risk stage II
Nurse navigator role: stoma education pre-op, MDT coordination, support through treatment

Screening

Colonoscopy every 10 years from age 50 (or earlier if family history)
Faecal occult blood test (FOBT) / faecal immunochemical test (FIT) as primary screening tool in national programmes
Polypectomy during colonoscopy reduces CRC incidence by ~80%

Bowel Obstruction

Mechanical Obstruction

Physical blockage — lumen, wall or external compression
Causes: adhesions (most common post-surgery), hernias, malignancy (GCC: CRC rising), volvulus, intussusception, gallstone ileus
Features: colicky pain, distension, nausea, vomiting (faeculant in late obstruction), absolute constipation (no flatus)
AXR: dilated loops (>6 cm small bowel, >9 cm large bowel), air-fluid levels; no gas beyond obstruction

Functional Ileus (Pseudo-obstruction)

No mechanical obstruction — failure of peristalsis
Causes: post-operative, sepsis, metabolic (hypokalaemia, hyponatraemia), drugs (opioids, anticholinergics)
Ogilvie syndrome: acute colonic pseudo-obstruction — massive caecal dilation; perforation risk if >12 cm
Management: treat underlying cause, ambulation, neostigmine (if no mechanical obstruction confirmed)

Nursing Management

Nasogastric decompression: NG tube free drainage + regular aspiration; reduces vomiting and aspiration risk; measure and document output
IV fluids: replace NG losses with 0.9% NaCl + KCl; strict fluid balance
Nil by mouth: until obstruction resolved or operative intervention
Surgical consult: strangulated hernia or signs of ischaemia (fever, peritonism, WBC rise) → emergency laparotomy
Monitor: urine output, electrolytes (hypokalaemia worsens ileus), lactate (ischaemia marker), vital signs

⚠ Strangulation emergency: If ischaemia develops — severe constant pain, fever, tachycardia, raised WBC/lactate — patient needs emergency surgery within hours. Mortality rises significantly with delayed intervention.

Upper GI Endoscopy (OGD)

Upper GI Endoscopy (OGD) — Nursing Care

Pre-procedure

Consent: ensure written informed consent obtained by endoscopist; explain procedure, risks (perforation rare 1:10,000, bleeding, aspiration), sedation options
Fasting: nil by mouth 6 hours for food, 2 hours for clear fluids (check local policy)
Medications: confirm regular medications taken; anticoagulants — discuss with team (warfarin may need bridging, DOACs usually omit morning dose)
IV access: 18–20G IV cannula — required for sedation or emergency
Sedation choice: throat spray (lidocaine 10% — topical anaesthesia) alone, or IV sedation with midazolam 2–5 mg (titrated) ± fentanyl; flumazenil reversal available
Allergy check: latex, lidocaine, sedation agents; document
Baseline obs: HR, BP, SpO2, RR, GCS; weight for sedation dosing

During Procedure

Position: left lateral (recovery position); pillow between knees for comfort
Mouthguard: protect teeth and endoscope; bite block in place throughout
Monitoring: continuous SpO2, HR; BP every 5 minutes; ECG if cardiac history
Suction: Yankauer on standby — aspiration risk especially with sedation; be alert for vomiting
Supplemental oxygen: via nasal cannula 2 L/min routinely when sedated
Nurse role: patient reassurance, airway monitoring, specimen labelling (biopsies), documentation of findings

Post-procedure Recovery

Monitor until gag reflex returns (if throat spray used) — typically 30–45 min
If sedated: recover until patient awake, orientated, GCS 15, SpO2 ≥95%; minimum 1 hour
Nil by mouth 30 minutes after throat spray (aspiration risk)
First oral intake: small sips of water; check swallowing before advancing diet
Throat soreness and mild bloating from air — normal; advise patient in advance
Discharge criteria: awake, orientated, stable obs, tolerating fluids, escort present (if sedated); not to drive for 24 hours post sedation
Give written aftercare advice and results

⚠ Complications to watch for: Perforation (sudden pain, surgical emphysema, deteriorating obs), bleeding (haematemesis, falling BP), respiratory depression (sedation — give flumazenil, bag-mask if needed). Severe adverse events are rare (<1:1000 diagnostic OGD).

Colonoscopy Nursing

Colonoscopy — Nursing Care

Bowel Preparation

Prep Agent	Regimen	Key Instructions
MoviPrep (PEG + electrolytes)	2 L evening before + 1 L morning of (split dose preferred)	Stay near toilet; clear fluid diet 24 h before; stop iron supplements 1 week prior
Picolax (sodium picosulfate)	1 sachet afternoon before, 1 sachet morning of	High fluid intake essential (≥2 L clear fluids per sachet); avoid in renal impairment
Plenvu	1 L evening, 500 mL morning; smaller volume	Useful for patients finding large volumes difficult; follow with extra clear fluids

Dietary Restrictions

2 days before: low-residue diet (white bread, pasta, chicken, fish, eggs; avoid high-fibre, seeds, nuts, skins, red meat)
Day before: clear fluids only (water, clear juice without pulp, broth, jelly — avoid red/purple coloured liquids)
Morning of procedure: nil by mouth (or clear fluids 2 h before as per protocol)

During & After Colonoscopy

Position: begin left lateral; repositioning may be needed (prone, supine) as scope advances to caecum
Sedation: IV midazolam ± fentanyl or pethidine; Entonox in some centres
Scope technique awareness: nurse assists with abdominal pressure when requested by endoscopist to prevent looping
Post-procedure: recover as for OGD; wind pain is normal — air insufflation used during procedure; may pass flatus loudly — reassure patient this is expected
First meal after recovery: light diet; observe for polypectomy site bleeding

⚠ Post-colonoscopy discharge advice: Return immediately if heavy PR bleeding, severe abdominal pain, fever, or dizziness within 7 days — may indicate perforation or post-polypectomy bleed. No driving for 24 h post sedation. No major decisions or alcohol for 24 h.

Stoma Nursing Care

Stoma Care for GCC Nurses

Types of Stoma

Type	Location	Effluent
Ileostomy	RIF (right iliac fossa)	Liquid/semi-liquid, high volume (500–1500 mL/day), green-brown
Colostomy	LIF (left iliac fossa) — usually sigmoid	Formed/semi-formed stool
Urostomy (ileal conduit)	RIF — urine diverted via ileal segment	Urine; bag drains continuously; night bag recommended
Loop stoma	Temporary — two openings in one loop	Functioning + mucous fistula

Stoma Assessment

Colour: healthy = red/pink/moist; pale/dark/dusky = ischaemia — urgent review
Output: document volume, colour, consistency per shift; ileostomy >1500 mL/24h = high output
Peristomal skin: should be intact; erythema, excoriation, rash requires skin barrier products
Stoma height: should protrude 1–2 cm (ileostomy); flush/retracted = leakage risk
Prolapse, hernia: document size; hernia common long-term complication

Pouch Change Technique

Wash hands; prepare equipment (flange/baseplate, bag, barrier cream, stoma measuring guide, scissors, wipes)
Remove old pouch gently — push skin away rather than pulling appliance
Clean peristomal skin with warm water; pat dry (soap may interfere with adhesion)
Measure stoma with guide; cut flange 2–3 mm larger than stoma to prevent mucosal compression
Apply skin barrier/protective film if skin sore; allow to dry
Warm flange (body heat for 30 sec) to improve adhesion; apply centrally, smooth from centre outward
Attach bag, ensure closure clip secure; document output and skin condition

GCC-Specific Stoma Considerations

Halal pouching products: confirm with patient that adhesives and materials are acceptable; some products contain porcine-derived components — many manufacturers now offer porcine-free alternatives; check SPC/manufacturer
Showering vs bathing: stoma may be showered over; bathing is generally safe though soaking may loosen adhesive; advise on timing of pouch changes relative to bathing
Prayer positions (Salah): prostration (sujood) places pressure on abdomen — ensure pouch is secure and emptied before prayer; consider convex or flatter flange; Islamic scholars generally rule that stoma does not invalidate prayer (consult with hospital Imam for patient support)
Dietary adjustments: traditional GCC foods — rice dishes, legumes (chickpeas, lentils) increase gas; patients should eat slowly, chew thoroughly; onions, carbonated drinks increase gas output
Hydration: ileostomy patients at high risk of dehydration in hot GCC climate — minimum 2 L fluid/day; oral rehydration solutions (St. Mark's solution) if high output
Ramadan: fasting may reduce output; medication timing with ileostomy — oral drug absorption may be reduced; advise patient to discuss with gastroenterology team before Ramadan

● High Output Ileostomy Management: Output >1500 mL/day — risk of dehydration, electrolyte imbalance (hyponatraemia, hypokalaemia, hypomagnesaemia). Treat with oral rehydration, loperamide (up to 16 mg/day), codeine, dietary modification. IV fluids if severe. Stoma nurse specialist referral essential.

GCC GI Epidemiology

GCC Gastroenterology — Epidemiological Context

Rising Conditions

Colorectal cancer: incidence rising significantly — linked to rapid dietary westernisation, high prevalence of obesity (35–40% in GCC adults) and T2DM, low physical activity, low fibre intake; presenting at younger ages than Western counterparts
NAFLD/NASH: extremely prevalent — parallels GCC obesity and T2DM epidemic; rates estimated 30–40% in general adult population; leading cause of liver cirrhosis progression alongside hepatitis B/C; see Liver Failure guide for details
GORD & PUD: highly prevalent; spicy/fatty traditional foods, high H. pylori rates in some groups, use of traditional herbal remedies that may irritate gastric mucosa

Comparative Context

H. pylori rates: 20–30% in GCC adults — moderate compared to 50–80% in parts of South/Southeast Asia and Africa; lower gastric cancer rate than East Asia where H. pylori + dietary factors (high salt) combine
IBD: historically low in GCC but incidence increasing — likely related to westernisation of diet, reduced childhood infections (hygiene hypothesis), changing gut microbiome
Hepatitis B/C: Hep C endemic in some GCC subpopulations (Egypt origin — highest global prevalence historically); Hep B more prevalent than Western Europe; GCC nationals generally lower rates
Gallstone disease: high rate linked to obesity and metabolic syndrome; cholecystitis and choledocholithiasis common in GCC hospitals

Ramadan Fasting & GI Disease

Ramadan Fasting Effects on GI Health

Ramadan fasting involves complete abstinence from food and fluid from dawn (Fajr) to sunset (Maghrib) — typically 12–18 hours depending on location and season. GI nurses must understand implications for patients with GI conditions.

GORD During Ramadan

Prolonged fasting → increased basal acid secretion
Large Iftar meal rapidly consumed → increased gastric pressure, LOS relaxation
Lying down shortly after Iftar worsens nocturnal reflux
Advice: eat Iftar slowly, avoid large volumes in one sitting, maintain 2–3 hours before lying down, continue PPI (take at Iftar time)
Suhoor meal (pre-dawn) helps maintain acid suppression

Peptic Ulcer Disease

Extended fasting increases acid production without food buffering
PPIs: take at Iftar and/or Suhoor (double dosing if twice daily needed)
Active PUD — patient may require medical exemption from fasting; discuss with gastroenterologist
Medication timing: triple therapy regimens during Ramadan — complex; requires careful pharmacist counselling

Constipation

Common during Ramadan — reduced fluid intake, less physical activity, change in dietary pattern
Advise: adequate fluid intake at Iftar through Suhoor, include fruits (prunes, figs — culturally appropriate), increase physical activity in the evening
Laxatives: osmotic laxatives can be taken at Suhoor; suppositories generally do not break fast per Islamic ruling but confirm with patient's religious authority

IBD During Ramadan

Mild IBD: many patients fast without significant flare
Active moderate-severe IBD: advise against fasting; medical exemption appropriate
Biologics: infliximab infusions can be timed to avoid fasting hours; adalimumab SC injection — needle breakage of skin is generally accepted as not breaking the fast per majority of scholars
Nutritional supplements: Ensure/Fortisip (liquid nutrition) — confirm halal certification

GCC Dietary Issues

Common GCC Dietary Issues Relevant to GI Health

Dietary Patterns

High refined carbohydrates: processed white rice (staple), white bread, sugary desserts — low fibre, rapid absorption → constipation, metabolic syndrome, NAFLD
Low fibre intake: traditional GCC diet historically lower in fruit/vegetables than Mediterranean; rapid urbanisation reduced use of traditional high-fibre foods (harees, lentil dishes)
Excess ghee/fat: clarified butter used extensively in cooking — high saturated fat → NAFLD, GORD trigger, cholesterol gallstones
Dehydration risk: hot arid climate (summer >45°C), outdoor workers particularly at risk; inadequate fluid intake worsens constipation, increases kidney stone risk, can trigger ileus post-operatively

Nursing Education Points

Encourage soluble fibre sources culturally acceptable to GCC patients: dates (in moderation), lentils, chickpeas, oats, barley (traditional)
Water intake minimum 2 L/day; increase to 3 L in summer — communicate clearly given heat
Mediterranean-style diet evidence for NAFLD — olive oil, fish, legumes; culturally many GCC populations have access to these
Reduce fast food — rapidly growing fast food culture in GCC particularly among younger generations
Tea after meals common — tannins may reduce iron absorption (relevant in IBD patients with iron deficiency)
Expat workers: dietary variety, potential vitamin D deficiency (counterintuitive given sun exposure due to indoor work/modest dress), low fibre diets
