blind loop syn·drome
stagnation of intestinal contents with bacterial overgrowth, producing substances that interfere with absorption of fat, vitamins, and other nutrients; usually occurs in a portion of small intestine that has been excluded from the flow of chyme.
Management Antibiotics—e.g., T-S—loop shortening, afferent-to-efferent or Roux-en-Y anastomoses or gastrojejunostomy
blind loop syndromeAfferent loop syndrome, stagnant loop syndrome Surgery A complication of Billroth II subtotal gastroenterostomy–end-to-side enteroenteric anastomosis that may arise long after surgery; the afferent loop consists of duodenum and a variable portion of jejunum, a loop that is a temporary reservoir for 1-1.5 liters of biliary and pancreatic secretions; after a fatty meal, the contents of a partially obstructed afferent loop ↑ and 'explosively' enter the stomach and may be regurgitated as greenish bilious fluid; other Sx include intermittent diarrhea due to disaccharidase deficiency, abdominal 'colic', hemorrhage, vitamin deficiency and neurologic Sx; with prolonged partial obstruction, the stool is steatorrheic–bulky, gray, and greasy, accompanied by weight loss; complete blind loop obstruction may be a medical emergency with rapid deterioration, shock, and perforation peritonitis Treatment Antibiotics–eg, T-S, loop shortening, afferent-to-efferent or Roux-en-Y anastomoses or gastrojejunostomy
