RT Journal Article SR Electronic T1 Annular pancreas and intermittent duodenal obstruction in an alcoholic adult JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 208 OP 210 VO 59 IS 2 A1 James C. Sperrazza A1 Richard A. Flanagan, Jr A1 Mark R. Katlic YR 1992 UL http://www.ccjm.org/content/59/2/208.abstract AB Annular pancreas is a congenital anomaly which, though present at birth, may cause few symptoms until adulthood. A case of annular pancreas with intermittent duodenal obstruction is described in a 49-year-old alcoholic man. Few other entities cause such obstruction. In similar cases, clinical suspicion of annular pancreas may lead to prompt diagnosis and treatment.
