The Epidemiology of Chronic Digestive Disease

Each section of the book is followed by a general discussion, often the most probing part of the proceedings.For while the papers naturally emphasise the exciting explosion of knowledge in this field over the past few years, the discussions reveal how little we still know about the natural history, epidemiology, and pathophysio- logy of this common disease.Should we strive to diagnose a condition which often remains asymptomatic-or does it?Should we always advise treat- ment?Can we prevent gallstones recur- ring after medical or surgical treatment?Or are all duct stones in patients after cholecystectomy retained stones?These questions are all discussed if not answered.So in spite of occasional imbalance in the discussion, inevitable in symposium pro- ceedings, the book does tackle real issues, and would be an interesting addition to any library.
