Traumatic hernias are rare, but have been associated with high-impact blunt trauma (eg high-velocity motor vehicle accidents or sports injuries, such as downhill skiing or mountain biking) that produces increased intra-abdominal pressure sufficient to disrupt the abdominal wall musculature.
Elevated PPV and SVV cut-off values for discriminating fluid responsiveness might be expected under conditions of pneumoperitoneum combined with steep Trendelenburg position, because elevated intra-abdominal pressure shifts the diaphragm cephalad, leading to increased intrathoracic pressure and stiffened abdominal part of the chest wall (27).
As reported in the literature, migration of the peritoneal catheter into the scrotum in our patient was due to a patent processus vaginalis and an additional effect on increased intra-abdominal pressure.
Various factors have been implicated, such as hyperacidity, long afferent loop, jejunal spasm with abnormal motility, increased intra-abdominal pressure, retrograde peristalsis, etc.

An important rote of the pelvic floor in relation to continence is maintenance of the angle between the bladder and posterior urethra, which ensures that any increase in intra-abdominal pressure (eg with coughing) is transmitted equally to all sides of the urethra, as well as the bladder.
