This book offers a comprehensive description of the main surgical treatments for adrenal tumors, encompassing both open surgery and laparoscopy. Introductory chapters cover surgical anatomy, pathology, the clinical diagnostic pathway, the role of different imaging techniques, and perioperative management. After discussion of general principles of adrenal surgery and instrumentation, individual surgical techniques are described in detail with the aid of step-by-step color photos and schematic drawings. For each procedure, careful attention is paid to indications and contraindications and to the most frequent complications. A further feature is the inclusion of numerous helpful decision-making algorithms for diagnosis and treatment. The text is structured according to the principles of "best practice" and the guidelines on evidence-based medicine and will thus be a valuable tool for practitioners in their clinical work.
