We recently treated a patient with PDPV, which stimulated a review of the disease process, including diagnosis, association with other anomalies, and surgical treatment.
REPORT OF A CASE
A 73-year-old woman was admitted to our hospital for treatment of epigastric pain of 3 months' duration. Her medical history revealed cholecystostomy for acute cholecystitis and gastrojejunostomy for asymptomatic stenosis of the second portion of the duodenum at age 32 years and cholecystectomy at age 42 years. A barium study of the upper gastrointestinal tract showed partial obstruction in
