Cloacal Malformations: Case Studies (Pediatric Colorectal Surgery) 1st Edition

Within the field of pediatric colorectal and pelvic reconstruction, the most complex anatomic problem a pediatric surgeon can face is that of a cloacal malformation. The urinary tract, gynecologic system, and distal bowel all fuse into a single common channel which must be surgically reconstructed. The care of patients with a cloaca is daunting, and the spectrum of anatomic variations very wide. In this book about cloaca, the authors have brought organization to the complex, providing basic principles of care, from fetal and newborn management to the reconstruction of bowel, gynecologic systems, and urinary tracts as well as the care of patients after surgery to puberty and beyond.

This is a comprehensive account of all elements of care for the cloaca patient. It includes preoperative evaluation and surgical planning, the anorectal malformation (ARM) index, surgical reconstruction, urological evaluation and long-term care. Also covered are the gynecologic evaluation and intervention, neurological implications, bowel management and the long-term management of patients with cloacal malformations. Case studies provide valuable insights into a wide range of clinical scenarios, never previously categorized so comprehensively. These studies enable the reader to understand and gain experience from detailed descriptions. Fully illustrated, in color, and with further resources available online, this is a unique resource for all clinicians within the pediatric team caring for patients with cloacal malformations.

In addition, specialists across numerous fields, including colorectal surgery, urology, gynecology, and gastrointestinal motility, as well as neonatology, orthopedics, neurosurgery, anesthesia, radiology, psychology, social work, nutrition, and nursing, will find this practical clinical text and its online resources to be an invaluable when dealing with the complex needs of the cloaca patient.
