Ever since the publication of the first edition in 1997, the ''Companion to Specialist Surgical Practice'' series has met the needs of surgeons in higher training and practising consultants by providing contemporary, evidence-based information on the sub-specialist areas relevant to their general surgical practice. All eight volumes are thoroughly edited and supported by evidence-based references to support key recommendations. This new Fourth Edition brings together the relevant state-of-the-art specialist information that the editors and authors consider important for the practising sub-specialist general surgeon. Purchase of a print book also includes a downloadable version of the eBook.
