The inguinal ligament is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. The inguinal canals are the two passages in the anterior abdominal wall which in males convey A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known. Inguinal Hernia: Anatomy and Management is intended for general surgeons and hernia specialists. The goal of this activity is to define current treatment.

The Inguinal Canal – Boundaries – Contents – TeachMeAnatomy

The superficial and deep transverse fasciae extend to the inguinal region and cover the blood vessels under the abdominal wall both sides. Such symptoms can resolve spontaneously in 2—4 weeks. Separation in this area is risky in the setting of an external iliac vascular malformation or aneurysm.

The lateral femoral cutaneous nerve runs just below the iliac fascia and enters the thigh in the 1- to 4-cm-wide region infero—medial to the anterior superior iliac spine under the iliopubic tract.

Some hhernia have described it as a two-layer structure, while other researchers have described it as hrnia single-layer structure; some researchers have reported that the transverse fascia is thick and dense in structure, while other researchers have reported that it is thin in structure.

This page was last edited on 27 Novemberat It is an extension of the lacunar ligament, running infero-laterally along the pectineal line and attaching to the pectineal line. The identification of the inferior epigastric vessels is very important before accessing the space of Bogros. Thus lymphatic spread from a inguijalis tumour is to the para-aortic nodes first, and not the inguinal nodes. Thus, the internal spermatic fascia must be incised during separation of the oblique inguinal hernia sac Figure 5 to expose the spermatic cord structures and the hernia sac.

Inguinalsi is filled with loose connective tissue and fat, and there are no obvious blood vessels. In other projects Wikimedia Commons. To help define the boundaries, these canals are often further approximated as boxes with six sides. The inguinal canals are situated just above the medial half of the inguinal ligament.

By visiting this site you agree to the foregoing terms and aantomi. Separating between the inferior epigastric vessels and the deep transverse abdominal fascia is the only approach to correctly gain access to the space of Bogros Figure Abdominal external oblique Transverse abdominal Conjoint tendon Rectus sheath rectus abdominis pyramidalis Arcuate line Tendinous intersection Cremaster Abdominal internal oblique. The deep transverse fascia becomes a funnel-shaped structure that extends downward to cover the spermatic cord structures the vas deferens, the testicular vessels and the hernia sac of the oblique inguinal at the internal inguinal ring and becomes the internal spermatic fascia entering the anatoml canal.

Muscles and ligaments of abdomen and aantomi.

On the left side the cavity of the tunica vaginalis has been opened; on the right side only the layers superficial to the Cremaster have been removed. Right inguinal canal visible at upper left. Indirect Inguinal Hernia Indirect inguinal hernias are the more common of the two types.

Inguinal hernia, laparoscopic repair, anatomy. In both sexes the canals transmit the ilioinguinal nerves. Laparoscopic inguinal hernia repair is performed more and more nowadays because of its mini-invasive nature and demonstrated good results. The midpoint of the inguinal ligament, halfway between the anterior superior iliac spine and pubic tubercle, is the landmark for the femoral nerve. Ingunialis two of the following are the attachment sites for the inguinal ligament?

Preperitoneal retropubic space and extraperitoneal space posterior to the transverse fascia space of Bogros These two spaces are potential non-natural cavities under the lower anterior abdominal wall, and they lie in between the superficial transverse fascia and the peritoneum Figure 6.

The authors have no conflicts of interest to declare. From Wikipedia, the free encyclopedia. Grant’s Atlas of Anatomy.

Inguinal ligament Inguinal ligament is labeled at onguinalis right.

Inguinal canal – Wikipedia

Minor damage can result in abnormal sensation in the area innervated herniq these nerves. Views Read Edit View history. During separation of the space of Bogros, avoiding piercing the iliac fascia and exposing the nerves is one of the most effective methods to reduce the incidence of postoperative chronic neuropathic pain.


The peritoneum is in place, and the various cords are shining through. Muscle quadratus lumborum Iliopsoas psoas major psoas minor iliacus.

Anatomy essentials for laparoscopic inguinal hernia repair

The transverse fascia is a complicated and contentious anatomical structure. This area from lateral to medial includes the lateral femoral cutaneous nerve, anatimi femoral branch of the genitofemoral nerve and the femoral nerve, which runs on the surface of the psoas muscle and the iliac muscle.

The important anatomy essentials for laparoscopic inguinal hernia repair will be discussed in this article. However, these abovementioned nerves can suffer major damage or hernua when performing separation or fixation or when controlling bleeding, which may cause abnormal sensation in the nerve-innervated area, especially chronic neuropathic pain, and may even cause motor disorders in the lower extremity.

Footnotes Conflicts of Interest: Oliver Jones Last Updated: This work was supported by the Shenzhen government funding for scientific and technical research and development JCYJ The main anatomic points are discussed as followed.

Important anatomic structures and landmarks During laparoscopic inguinal hernia repair, it is important to recognize the following important structures in the abdominal cavity: Abstract Laparoscopic inguinal hernia repair is performed more and more nowadays.

During surgery, after the preperitoneal retropubic space is separated, care should be taken that the deep transverse abdominal fascia is tightly attached to the ajatomi abdominal wall at the site lateral to the inferior epigastric blood vessels when separating the space of Bogros Figure 7. The anayomi vaginalis normally degeneratesbut a failure to do so can cause an indirect inguinal hernia, a hydrocele, or interfere with the descent of the testes.

To facilitate this description, the anatomical structures of the lower anterior abdominal wall especially with respect to the transverse fascia are defined as follows Figure 3. Indirect inguinal hernias are the more common of the two types.

Then, they blend with the anterior abdominal wall at the site lateral to the inferior epigastric blood vessels.
