Deep Inguinal Ring Hernia

They are caused by the failure of the processus vaginalis to regress.

Deep inguinal ring hernia. Bowel can then exit the canal via the superficial inguinal ring and form a lump in the scrotum or labia majora. Indirect inguinal hernia differences between indirect and direct inguinal hernias. Located midway between anterior superior iliac spine and pubic tubercle it is bounded medially by the lateral umbilical fold inferior epigastric vessels and inferiorly by. The herniated loops of small intestine pass through the deep inguinal ring into the inguinal canal it may emerge through the superficial inguinal ring and descend into the scrotum.

If large enough it emerges through the external ring and descends into the scrotum. The peritoneal sac and potentially loops of bowel enters the inguinal canal via the deep inguinal ring. An indirect inguinal hernia comes through the deep inguinal ring and hence traverses the whole extent of the canal. Inguinal region is considered as a weak spot in the lower abdomen owing to the presence of superficial deep inguinal ring and the inguinal canal.

This is in contrast to an indirect inguinal hernia where bowel enters the inguinal canal via the deep inguinal ring. Deep in gui nal ring ta the opening in the transversalis fascia through which the ductus deferens and gonadal vessels or round ligament in the female enter the inguinal canal. Direct hernias are acquired usually in adulthood due to weakening in the abdominal musculature. An inguinal hernia is an abnormal protrusion of intra abdominal contents either through the deep inguinal ring indirect inguinal hernia.

Figure 3b shows a sagittal view of an indirect inguinal hernia exiting the abdominal cavity through deep inguinal ring anterior to the inferior epigastric vessels during valsalva. A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall thereby bypassing the inguinal canal is known as a direct inguinal hernia. It is contained inside the coverings of the spermatic cord. Both types of hernia can exit the via the superficial ring and emerge within the testes.

Medial to the inferior epigastric artery inguinal hernias are often asymptomatic presenting as a painless swelling in the groin. Figure 3a shows a left indirect inguinal hernia in cross section. Indirect inguinal hernias are the more common of the two types. Lateral to the inferior epigastric artery or through the weakened posterior wall of the inguinal canal direct inguinal hernia.

Indirect inguinal hernia oblique inguinal hernia. Hesselbach s triangle is also considered as a weak spot of the groin through which abdominal contents may protrude is labeled as direct inguinal hernia. Both types of inguinal hernia can present as lumps in the scrotum or labia majora. Please note that it is more common for indirect inguinal hernias to do this as the path through both anatomical inguinal rings rather than a muscle defect has less resistance.

The indirect inguinal hernia is located anterior and lateral to the inferior epigastric vessels.
