Risk factors for future complications: age < 50, male sex, length > 2 cm, abnormal tissue
Surgical risk of resection is low when performed by experienced surgeon
No consensus; shared decision-making with patient and surgeon
Meckel scan optimization
Pretreatment enhances diagnostic yield
H2 blocker pretreatment reduces false negatives from tracer washout
Fasting essential before scan
False positive and false negative management
Negative scan does not exclude Meckel in high-clinical-probability cases
Clinical Diagnostic Predictive Score >= 6 may justify direct surgery
Capsule endoscopy or device-assisted enteroscopy for inconclusive cases
Evidence base for management decisions
ACG Clinical Guideline on Small Bowel Bleeding (Gerson et al. 2015)
Capsule endoscopy first-line for obscure GI bleeding after negative upper and lower endoscopy
Device-assisted enteroscopy for therapy after capsule identification

Patient Discharge Instructions
copy discharge instructions
Home care instructions after Meckel diverticulum evaluation
If sent home after a self-limited bleeding episode
Your child or you had a GI bleed that has stopped and you are stable enough to go home
A follow-up test (Meckel scan) or surgery may be arranged
Keep all scheduled follow-up appointments with surgery or gastroenterology
Activity and diet
Resume normal diet as tolerated after bleeding has stopped
Avoid NSAIDs (ibuprofen, naproxen, aspirin) as they can worsen bleeding from the stomach lining within the diverticulum
No specific dietary restrictions unless instructed by surgeon
Return to emergency department immediately if
Rectal bleeding returns or worsens
Any passage of bright red, dark red, or maroon blood from the rectum
Large clots passed rectally
Abdominal pain develops or worsens
Severe constant abdominal pain not relieved by position change
Abdominal swelling or rigid abdomen
Vomiting, especially green or yellow bile-colored vomit
This can indicate a bowel blockage and is an emergency
Signs of blood loss or anemia
Dizziness, lightheadedness, or fainting
Rapid heart rate or feeling the heart pounding
Pale skin or lips
Fever above 38.5 C (101.3 F)
May indicate infection, diverticulitis, or perforation
Child is unusually lethargic, inconsolable, or cannot keep fluids down
Dehydration and serious illness risk in young children
Follow-up instructions
Surgical follow-up within 1-2 weeks if managed without surgery
Meckel scan may be scheduled as outpatient
Surgical resection may be planned electively
After surgery
Standard post-operative wound care as instructed
Diet advancement: clear liquids first, then soft diet, then regular
Return to full activity typically within 2-4 weeks after uncomplicated laparoscopic resection
Post-operative adhesive bowel obstruction is a rare late complication (approximately 2%)
