Foreword
One of the rewards of medical teaching is to see the next generation advance the art and
science of medicine beyond their forebears. We can be justifi ably proud of this anthology
on Perineal and Anal Sphincter Trauma, which owes so much to the endeavours of the
editorial team. In addition to their own contributions, they have recruited a body of
topic authors of international standing. The result is a book of wide breadth and depth,
covering many aspects of disorders of the posterior pelvic compartment, which have
hitherto not been found in one volume. The choice of topics is wide, and the description
and illustrations are clear and concise. They cover both innovative and current practice,
all founded on an evidence basis.
The intended readership is multidisciplinary, going beyond all those involved in
“front line” obstetric care, to reach physicians, surgeons, radiologists and others, who
deal with long term adverse effects of childbirth. This mirrors the professional back-
ground of the authorship. We are confi dent of its broad appeal and wish the book every
success.

Preface
In the last two decades, there has been an increasing interest in obstetric perineal and
anal sphincter trauma. This can be largely attributed to innovations in imaging, as it
was the development of anal endosonography that led to the diagnosis of unrecognised
anal sphincter trauma during childbirth. These sonographic injuries were initially con-
sidered to be occult, but it has now been established that the vast majority are in fact
visible at the time of childbirth but remain undiagnosed. Consequently, attention is now
focused on structured training programmes and hands-on workshops to improve under-
standing of anatomy and repair of perineal and anal sphincter trauma.
However, despite primary repair of anal sphincter injuries, the outcome is not uni-
versally optimal, and research on the ideal management continues. This highlights the
need to identify risk factors in order to minimise the development of perineal and anal
sphincter trauma.
This textbook aims not only to address these issues but also to provide in-depth
information about anatomy and pathophysiology. In addition, other issues such as
female genital mutilation, the management of faecal incontinence and medicolegal
implications are also covered.
In producing this book, we would like to acknowledge our mentors for their teaching
and inspiration, the patients who made us question our practice and the research fellows
who contributed to the research. We would like to thank the multidisclipinary authors
for their timely submission of chapters; last but not least we would like to extend our
appreciation to our families for their perseverance and understanding.
