K. Mithofer et Al. Warshaw, RECURRENT ACUTE-PANCREATITIS CAUSED BY AFFERENT LOOP STRICTURE AFTER GASTRECTOMY, Archives of surgery, 131(5), 1996, pp. 561-565
Afferent loop obstruction after gastrectomy and Billroth II gastrojeju
nostomy is only rarely diagnosed as the cause of recurrent acute pancr
eatitis. Three patients are described in whom afferent loop stricture
after gastrectomy and Billroth II reconstruction manifested as recurre
nt pancreatitis 13 to 24 years after the initial procedure. Late onset
, nonspecific symptoms, and other simultaneous gastrointestinal pathol
ogic features promoted a chronic clinical course in all patients. Symp
toms included acute abdominal pain, vomiting, jaundice, hyperamylasemi
a, weight loss, and anemia. A thorough history, barium examination, ch
olescintigraphy, and endoscopy were central in establishing the diagno
sis. The pathogenesis of stricture formation is thought to be ischemic
mucosal damage from intestinal crossclamping. Surgical decompression
provided lasting relief of the symptoms. Afferent loop stricture shoul
d be considered in the differential diagnosis in patients with recurre
nt acute pancreatitis and previous gastrectomy with Billroth II recons
truction.
