The 57 authors in this new work have been preeminent investigators largely responsible for these advances and fortunately, under the dual editorship, have been able to incorporate this newer knowledge into a very readable standard textbook of gastroenterology.

By itself, it would make an admirable presentation of gastrointestinal physiology.
