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.

Muscle quadratus lumborum Iliopsoas psoas major psoas minor iliacus. The transverse fascia in the lower anterior abdominal wall is divided into two layers Figure 4. The gubernaculum then becomes two structures in the adult: August 7, Revisions: Otherwise, it is easy to accidentally damage the inferior epigastric vessels or pierce the peritoneum, which may cause difficulties while performing laparoscopic surgery or even require conversion to open surgery.
The walls of the inguinal canal are usually collapsed around their contents, preventing other structures from potentially entering the canal and becoming stuck. This area from lateral to medial includes the lateral femoral cutaneous nerve, the femoral branch of the genitofemoral nerve and the femoral nerve, which ijguinalis on the surface of the psoas muscle and the iliac muscle.
You can help by adding to it. The superficial external ring marks the end of the inguinal canal, and lies just superior to the pubic tubercle. These structures are the landmarks for making a correct diagnosis and performing accurate surgeries Figure 8. The inguinal xnatomi are the two passages in the anterior abdominal wall which in males convey the spermatic cords and in females the round ligament of uterus.
It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. This page was last edited on 27 Novemberat Direct inguinal hernias, oblique inguinal hernias and femoral hernias are all caused by weakness of the abdominal transverse fascia in myopectineal orifice Figure 1.
The surgical area refers to the main surgical field of a laparoscopic inguinal hernia repair.
Each testicle then descends through the abdominal wall into the scrotum, behind the processus vaginalis which later obliterates. Abdominal external oblique Transverse abdominal Conjoint tendon Rectus sheath rectus abdominis pyramidalis Arcuate line Tendinous intersection Cremaster Abdominal internal oblique. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. This section needs expansion. Anatlmi, the space of Retzius originally referred to the space formed by the fold of the tight fusion of the deep transverse fascia and the peritoneum between the bladder and the peritoneum, which includes the bladder and is filled with loose connective tissue.
The space between the superficial and deep transverse fascia is the parietal space.
There is some dispute over the attachments. If you do not agree to the foregoing terms and conditions, you should not enter this site. The anatomy of these procedures is totally different from traditional open procedures because they are performed from different direction and in different space.
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 — where the peritoneal sac enters the inguinal canal through the deep inguinal ring.
Which of the following forms the posterior wall of the inguinal canal? It is sometimes termed the Fallopian ligament. From Wikipedia, the free encyclopedia. Inguinal triangle Inguinal canal Deep inguinal ring Superficial inguinal ring Intercrural fibers Crura of superficial inguinal ring Inguinal ligament Pectineal ligament Lacunar ligament Reflected ligament. Clinical data have shown that the lateral femoral cutaneous nerve and the femoral branch of the genitofemoral nerve are more commonly damaged.
Thus, the deep transverse fascia should be incised at the attachment site to enter the space of Bogros.
Anatomy essentials for laparoscopic inguinal hernia repair
Important anatomic structures and landmarks During laparoscopic inguinal hernia repair, it is important to recognize the following important structures in the abdominal cavity: The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. The inguinal canal is bordered by anterior, posterior, superior roof and inferior floor walls. The inferior epigastric artery usually runs with two veins along the back of the rectus abdominis muscle toward the umbilicus.
Structures passing behind the inguinal ligament.

However, these abovementioned nerves can suffer major damage or entrapment when performing separation or fixation or when controlling bleeding, which may cause abnormal sensation in the nerve-innervated area, especially chronic neuropathic onguinalis, and may even cause motor disorders in the lower extremity. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment.
Discuss Proposed since August Indirect Inguinal Hernia Indirect inguinal hernias are the more common of the two types. The white iliopubic tract can be seen at the lower edge of a direct hernia ring or below an internal inguinal ring. Minor damage can result in abnormal sensation in the area innervated by these nerves. The sac is not covered with the coverings of the contents of the canal.
