What causes abdominal incisional hernia?

Abdominal incisional hernia may be related to anatomical factors, abdominal operation or decreased immunity.

1. Anatomical factors: the fibers of abdominal

muscle, fascia and sheath are mostly transverse. When longitudinal incision suture is performed, the suture is easy to slip between fibers, and the sutured tissue is easy to open incision under the transverse traction force to muscle, thus abdominal incisional hernia may occur.

2. Abdominal operation:

prolonged indwelling of drainage tube in abdominal wall, poor surgical suture, postoperative incision infection or early postoperative intra-abdominal pressure increase may cause incisional hernia.

3.

Factors such as malnutrition, diabetes mellitus, obesity or long-term steroid use in patients with decreased immunity may lead to poor healing of abdominal incisional hernia, which may cause incisional hernia.
