Suspected appendicitis three hours from a surgeon
A 26-year-old man presents to a rural clinic with 20 hours of abdominal pain that began around the umbilicus and settled in the right lower quadrant. He has anorexia, one episode of vomiting and low-grade fever. Temperature 38.0°C, pulse 104, BP 118/74 mmHg. The abdomen is guarded with maximal tenderness at McBurney's point, and Rovsing and psoas signs are positive. White cell count 14.6 × 10⁹/L with neutrophilia; CRP 68 mg/L; urine dipstick negative. The clinic has ultrasound but no CT and no surgeon on site. The nearest hospital with a surgeon and CT is 3 hours away by road; an ambulance is available now but may be delayed by 4–6 hours if not used immediately. He is otherwise healthy, not pregnant, and has no allergies.
1. How would you estimate the probability of appendicitis, and what does the score mean for this patient?
Read the worked answer
Use the Alvarado score as a structured estimate, not as a rule. This patient scores: migration of pain 1, anorexia 1, nausea/vomiting 1, tenderness in the right lower quadrant 2, rebound tenderness 1, fever 1, leucocytosis 2 = 9 out of 10. A score of 7 or more corresponds to a high probability of appendicitis, and a score of 9 is strongly suggestive.
Before acting, examine the hernial orifices and testes to exclude torsion, and consider mesenteric adenitis, terminal ileitis, ureteric colic, epiploic appendagitis, Crohn's disease and urinary tract infection. The urinalysis is negative, which makes urinary causes less likely but does not exclude them. The score cannot distinguish uncomplicated from perforated appendicitis, and clinical deterioration, generalised peritonitis or shock would override it.
2. Would you give antibiotics, arrange immediate transfer, or observe? Justify your answer.

Arrange immediate transfer for surgical assessment. Give intravenous fluids, keep him nil by mouth, and give intravenous antibiotics - for example ceftriaxone 1 g plus metronidazole 500 mg - because early antibiotics reduce the risk of perforation and postoperative complications. Give adequate analgesia; opioids do not mask the diagnosis when used sensibly.
Do not delay transfer for CT or ultrasound. Ultrasound may be useful if it is immediately available and does not delay departure, but a normal scan does not exclude appendicitis. The 4–6 hour ambulance delay matters: perforation risk rises with time, so use the ambulance now. Non-operative management with antibiotics alone is an option in selected uncomplicated cases, but recurrence occurs in around 20–30% and there is no confirmed diagnosis here. If transfer became truly impossible, admit for observation, serial examination and antibiotics, with drainage of any abscess and interval appendicectomy considered later.
3. What would you tell the patient and document before transfer?
Read the worked answer
Tell him that the history and examination strongly suggest appendicitis, that the main risk is perforation, and that he needs a surgical assessment urgently. Explain the transfer plan, that he should not eat or drive, and that the antibiotics and fluids are treatment, not just preparation. Warn him that if the pain suddenly eases it may mean the appendix has perforated rather than settled, so he must report it.
Document the Alvarado score, the antibiotics and times given, fluid balance, the receiving hospital and clinician, the mode of transport and the observations before departure. Obtain informed consent for transfer and treatment, and check allergy status. Communicate directly by phone with the receiving surgical team and record the name and time. If he declines transfer, document capacity, the risks discussed and a safety plan, and offer close observation.
