Diagnosis: Small Bowel Obstruction (SBO)
The clinical triad of periumbilical/central colicky abdominal pain, vomiting/nausea, and green (bilious) stool is classic for mechanical small bowel obstruction.
Why this diagnosis fits:
| Feature | Significance |
|---|---|
| Periumbilical/central pain | Midgut (small bowel) visceral pain — poorly localized, crampy, colicky |
| Nausea & vomiting | Hallmark — proximal SBO causes early, profuse bilious vomiting |
| Green (bile-stained) stool | Indicates obstruction below the ampulla of Vater but contents still passing; bilious character confirms small bowel level |
Common Causes (Etiology)
- Adhesions (post-surgical) — most common, up to 75% of cases
- Hernias — external (inguinal, femoral) or internal
- Malignancy — local invasion or metastatic compression
- Crohn's disease — inflammatory strictures
- Volvulus / Intussusception
- Gallstone ileus, foreign body
Ask: Any prior abdominal surgery? (most likely adhesions) — Schwartz's Principles of Surgery, 11th Ed.
Investigations
Immediate:
- Plain X-ray abdomen (supine + erect): dilated small bowel loops, air-fluid levels, absent gas in colon — "ladder pattern"
- CT abdomen with contrast (gold standard): identifies level, cause, and complications (strangulation, perforation)
- FBC, U&E, LFTs, serum lactate — assess dehydration, electrolyte imbalance, ischemia
- Blood gas — metabolic alkalosis from vomiting
Treatment
1. Initial Resuscitation (Non-operative — "Drip and Suck")
- IV fluid resuscitation: Normal saline / Hartmann's — correct dehydration and electrolytes
- NBM (Nil by mouth)
- Nasogastric tube (NGT) insertion with free drainage — decompress stomach, reduce vomiting
- Urinary catheter — monitor urine output (target >0.5 mL/kg/hr)
- Analgesia (IV opioids — morphine/tramadol)
- Antiemetics
2. Conservative Management (for partial/non-strangulated SBO)
- Trial of 24–48 hours non-operative management
- Serial clinical examination and repeat imaging
- Water-soluble contrast (Gastrografin) challenge: both diagnostic (CT/follow-through) and therapeutic — promotes resolution in adhesive SBO
3. Surgical Management (Indications)
Surgery is urgent/emergency if:
- Signs of strangulation: fever, tachycardia, peritonism, rising lactate, leukocytosis
- Complete obstruction not resolving with conservative management
- Closed-loop obstruction (on CT)
- Perforation
Surgical options:
- Lysis of adhesions (adhesiolysis) — most common
- Hernia repair with bowel reduction
- Bowel resection + anastomosis if ischemic/gangrenous bowel
- Hartmann's procedure if grossly contaminated field
Red Flag Features (strangulation — surgical emergency)
- Fever, tachycardia, hypotension
- Peritoneal signs (guarding, rigidity, rebound)
- Elevated serum lactate
- Leukocytosis
- Pneumoperitoneum or mesenteric fat stranding on CT

Bottom line: This patient most likely has mechanical small bowel obstruction. Urgent CT abdomen is the investigation of choice. Initial management: IV fluids, NGT, NBM, monitoring. If no improvement or strangulation signs — surgical exploration.
