The only book to deal specifically with constipation for specialists has been updated to include all the new advances since the first edition (1995). These advances include biofeedback, surgery for constipation, sacral nerve stimulation, the use of laparoscopy for rectal prolapse, treament and our understanding of some of the psychological problems of these patients. Innovations also include Professor Norman Williams' Malone Procedure and the newer pharmacologic treatments such as nitric oxide and botulinum toxin injections.
