That stagnant or "blind" loops of small and large bowel are often accompanied by megaloblastic anemias has been known for over 60 years.1 Neurologic changes resembling those in true Addisonian pernicious anemia have also been noted in the "blind" loop syndrome, and are summarized by Reilly in his review.2
A case of anemia associated with neurologic changes that followed gastrointestinal surgery is presented.
In April, 1944, after having peptic ulcer symptoms for two years, a 32-year-old man was explored as an emergency, and a perforated duodenal ulcer was closed. After surgery he was almost asymptomatic for four years and then developed a sudden recurrence of epigastric distress. In August, 1948, a 50% gastric resection with a gastrojejunostomy reconstruction was performed. The pathological report of the specimen revealed no peptic ulcer. Because of obstructive symptoms he was reoperated on in October, 1948, and a large enteroenterostomy between the afferent
