Chronic obstructive pancreatitis due to tiny (0.6 to 8 mm) benign tumors obstructing pancreatic ducts: report of three cases.

摘要: Three cases of obstructive pancreatitis are described in nonalcoholic women aged 56 to 58 years with a 2-month 5-year history recurrent attacks pancreatic pain associated intermittent raised serum enzymes. The diagnosis was made by sonography showing an enlarged hyperechogenic tail the pancreas, dilated duct, rest pancreas being normal, and ERCP partial stenosis main duct regular dilatation collateral branches distally it. Surgical resection cured all three patients. In obstructed part lesions typical perilobular sometimes intralobular fibrosis same degree different lobules diseased area not patchy as chronic calcifying pancreatitis. changes ducts marked, there is absence intraductal plugs. Fat necrosis pseudocysts may be found. Tumors responsible for obstruction were smallest islet cell tumors (0.6 8 mm) serous cystadenoma (5 symptoms ever published. Cephalad stricture, normal. When etiology atypical, especially when it occurs greater than 50 years, careful (or computed tomographic scan) must done. Serial sections resected at level distal often necessary demonstrate tumor.
