Emergency surgery is performed on an acutely-ill patient who is at a high risk for death and other complications. Most surgically treatable emergencies fall within the purview of different specialties. Abdominal problems such as strangulated and incarcerated inguinal hernias, intestinal obstructions caused by volvulus, adhesions and worm infections, and appendicitis are certain abdominal conditions that require emergency surgery. Respiratory obstructions may arise due to trauma, tumors, head and neck infections, bleeding, etc. In cases where the obstruction is not resolved with change of position or insertion of a tube or an oral airway into the trachea, procedures such as tracheostomy or cricothyroidotomy may be required. Another condition that may require emergency surgery is urinary obstruction caused due to stones in the bladder obstructing the outlet, scarring of the urethra or an enlarged prostate compressing the urethra. In such cases, an emergency procedure called suprapubic cystostomy may be performed. This book contains some path-breaking studies in the field of emergency surgery. It outlines the procedures and practices that are the mainstay of modern emergency surgery in detail. This book includes contributions of experts and scientists which will provide innovative insights into this field.
