title: Primary gastrointestinal lymphoma complicated by common bile duct obstruction: report of two cases.
abstract: This report describes two cases, a case of primary small intestinal lymphoma and a case of gastroduodenal lymphoma both producing obstructive jaundice due to invasion of the common bile duct. Oesophagogastroduodenoscopy revealed the lesions and the endoscopic biopsies confirmed the diagnosis of lymphoma in both the cases. Ultrasound examination of the biliary system, followed by percutaneous transhepatic cholangiography, delineated the dilated biliary tree with distal obstruction of the common bile ducts. While radiotherapy alone was sufficient in the case of primary small intestinal lymphoma; drainage procedures were required in the case of gastroduodenal lymphoma to relieve the obstruction of the common bile duct.
