Pathophysiology and Management of Localized Adhesive Obstruction

Clinical Presentation

The American Gastroenterological Association notes that vomiting occurs first in localized adhesive obstruction as the bowel proximal to the obstruction distends and secretes fluid, followed by abdominal bloating from accumulated gas and fluid, and when the obstruction resolves, the accumulated fluid is released distally, resulting in watery diarrhea or loose stools 1, 2
The European Society of Gastrointestinal Endoscopy recommends considering the character of vomit to provide anatomic clues, with green/yellow vomit suggesting a more proximal obstruction, and feculent vomit indicating a distal obstruction 1, 2

The World Journal of Emergency Surgery suggests that a CT scan during an episode of severe pain can demonstrate the transition point between dilated and normal-sized bowel, confirming the diagnosis of localized adhesive obstruction 1, 2
The American College of Surgeons notes that visible small bowel peristalsis on examination or worsening pain after prokinetic drugs are additional clues to organic obstruction 1, 2

The World Journal of Emergency Surgery recommends initial management including nil per os, nasogastric decompression, fluid resuscitation, and electrolyte correction for patients with localized adhesive obstruction 4, 3, 5
The American Gastroenterological Association suggests that water-soluble contrast administration has both diagnostic and therapeutic value, significantly reducing the need for surgery 5
The Society of American Gastrointestinal and Endoscopic Surgeons indicates that surgery is indicated for signs of peritonitis, strangulation, ischemia, or failure of conservative management after 72 hours 4, 3, 5, 6
