Foreword
T he reader might wonder why another textbook on the anus is needed. There
are three main reasons. First anal disease is exceedingly common in all parts
of the world. Secondly treatment is effective in most cases, but when surgery
is performed badly the patient can be disastrously and often irreversibly
worse. Thirdly new developments in the understanding and treatment make
proctology a dynamic fi eld for research and its application to management.
The book is not on colon and rectal surgery but rather on proctology in
which anal pathology is set within the context of wider disease where rele-
vant. “A nus ” is edited by two internationally known and experienced sur-
geons who have themselves contributed to knowledge in the fi eld through
research, publications and teaching. They have brought together authors from
all over the world, who are recognized practitioners in the fi eld. The reader is
given an accurate account of the normal structure and function of the anus
including clinical and radiological anatomy and physiology. The importance
of histopathology is dealt with in a chapter dedicated to diagnosis and the
subsequent chapters then follow from congenital anomalies to neoplasia, pro-
lapse, incontinence, haemorrhoids, fi ssure and anorectal sepsis. There is a
section on dermatological conditions and sexually transmitted disease with
the book ending with an account of plastic procedures around the anus.
E very attempt has been made to incorporate new information regarding
etiology, diagnosis and treatment to give the reader an up-to-date account of
the subject. The use of Tables and Boxes to present data makes the book easy
to read. Many of the chapters contain high quality photographs to illustrate
diseases particularly those due to dermatological and sexual transmission.
The chapters on radiological pathological anatomy contain excellent illustra-
tions which are very useful since they summarise the various pathological
forms of anorectal sepsis and prolapse, enabling the reader to learn the radio-
logical counterpart of clinical examination . Each chapter contains a useful
bibliography which will in itself be a valuable resource enabling the reader to
gain access to the literature including classic publications and recent
developments.
The book will be valuable for consultant practitioners in proctology, but it
will also help colorectal surgeons, gastroenterologists, trainees, specialist
nurses and students who are interested in increasing their knowledge. Proctology
is in many ways still a largely clinical speciality and the theme throughout the

book implicitly recognizes this while at the same time it demonstrates where
investigations are either essential or likely to help clinical decision taking. It is
an authoritative, informed and up-to-date contribution to an important area of
disease.
