Hernioscopy: a simple application of single-port endoscopic surgery in acute inguinal hernias.

Strangulated hernia remains one of the most common emergencies encountered in general surgery. During induction of general or spinal anesthesia, the potential self-reduction of a gangrenous bowel can occur in approximately 1% of cases. In these cases, bowel viability can no longer be directly assessed unless a more extensive operation (laparoscopy or laparotomy) is performed. A simple alternative to unnecessary laparotomy or to a standard laparoscopy is a hernia sac laparoscopy (hernioscopy). Here, we presented 4 patients with a diagnosis of small-bowel obstruction secondary to incarcerated inguinal hernias, in which the incarcerated hernia content was evaluated by hernioscopy. Only 1 case presented persistent signs of bowel ischemia after hernia reduction and required a small-bowel segmental resection. All hernias were repaired using prosthetic tension-free technique. Hernia sac laparoscopy (hernioscopy), the introduction of the laparoscope through an open inguinal hernia sac, can be useful to evaluate the viability of the incarcerated hernia content, to avoid unnecessary laparotomy.
