Gastroenterology is a large subdivision of medicine and has been the major attraction for many students in medicine. The explosion of technology and knowledge has changed the diagnostic and therapeutic concepts in this field. The books on gastroenterology have become voluminous for this reason.
The book Snapshots in Gastroenterology published by M/s Jaypee Brothers Medical Publishers (P) Ltd, New Delhi, India, is designed to collate all the details in a bulleted and understandable form.
The book is aimed at a well read and sophisticated audience, and has a wealth of information essential and necessary for those interested in gastroenterology. Thoughtfully, it covers both the medical and surgical aspects of gastroenterology, making the presentation complete, but concise.
The photographs and the figures add the color and quality to this prized manual, which I hope will fulfill the needs of those practitioners of medicine, more so the students of medical schools.
