Straight and oblique hernias are two common types of inguinal hernias, and they have some differences in morphology, causes, and clinical manifestations. The characteristics of straight and oblique hernias are described in detail below.
First, the rectus hernia crypt is located above the rectus muscle, and the hernia is smaller, generally above the lateral border of the rectus abdominis muscle, and the hernia sac passes directly through the weak point into the groin. Straight hernias are easy to detect and manifest as a palpable bulge in the groin when the patient is repositioned, most often unilaterally.
The oblique hernia crypt is located on the medial side of the inguinal and enters the groin through the gap between the medial and lateral annular tendons, the transverse abdominal tendon and the anterior lower psoas longitudinal tendon, and then forms the hernia sac. Oblique hernia is relatively hidden, and the patient must go through factors that cause increased local pressure, such as body position and muscle relaxation, before it can form an oblique hernia. Oblique hernias are the most common type of inguinal hernia, and most patients have both oblique hernias.
Secondly, in terms of the cause of the disease, straight hernia is often caused by increased abdominal pressure, and common causes include coughing, standing for a long time, lifting weights, etc. The oblique hernia is mainly due to the gradual weakening of the rectus abdominis aponeurosis due to age, resulting in an increase in intra-abdominal pressure, which makes the intra-abdominal exudation easy, and when the pressure is too high, the intra-abdominal cavity is easy to enter the abdominal cavity through the intra-abdominal crypt and form an oblique hernia.
In addition, there are some differences in the clinical presentation of straight and oblique hernias. The bulge of a straight hernia is usually fuller, flattened, harder, and becomes more noticeable when coughing. Oblique hernias have softer bulges that usually reduce spontaneously when coughing, straining to urinate or defecate, but become more difficult to do so over time. Oblique hernias are often accompanied by symptoms such as swelling pain and dull pain.
Finally, there are also slight differences in the methods of straight and oblique hernias. In general, both straight and oblique hernias are surgical. Surgery for a straight hernia is mainly done by removing the hernia sac and tightening the hernia area to prevent the intra-abdominal organs from protruding again. Surgery for oblique hernias, on the other hand, requires repair of the abdominal wall defect and appropriate muscle sutures.
In summary, straight hernias and oblique hernias are two common types of inguinal hernias, and they have some differences in morphology, pathogenesis, and clinical manifestations. For both types of hernias, early detection and appropriate treatment are very important to avoid complications and improve the quality of life of patients. January Creation Incentive Program
