How to do carbon dating problems

As a result, the tissue weakens, and the sutures cut through the tissue, including the skin.

An incisional hernia is not to be confused with a surgical wound dehiscence; in an incisional hernia, the skin is healthy and has healed.In some cases, computed tomography (CT), ultrasound, or introduction of a contrast material into the area of herniation and subsequent x-ray analysis (herniography), can visualize an incisional hernia. Closing the defect in the abdominal wall with sutures may repair small hernias.Large incisional hernias often require more extensive treatment using one of many different open surgical repairs for incisional hernia that can be are performed (e.g., Babcock, Koontz technique), depending on the location, severity of the defect, and the surgeon's preference.Incidence and Prevalence: About 2% to 10% of the over one million abdominal surgeries performed each year result in incisional hernia (Nicks).Risk factors include weakened tissue integrity common in advanced age or debility, inadequate nutrition, a low-fiber diet that contributes to constipation and straining, obesity, pregnancy, and any action that increases pressure in the abdominal cavity.Although it is a treatment-related (iatrogenic) hernia, certain lifestyle factors and physical conditions may predispose individuals to develop of this type of hernia.

Incisional hernia results from the weakened condition of the superficial sheet of connective tissue that covers and joins the rectus abdominis muscles (fascial tissue called linea alba) along the surgical incision line.

The incision sometimes is closed using a patch of polypropylene mesh material as added support for weakened fascia.

As an alternative to open surgery, incisional repair with mesh implantation may be done using a lighted, flexible fiberoptic device (laparoscope) that allows visualization of the wound and inner abdomen.

The onset of an incisional hernia may be sudden or, more commonly, may happen in a delayed, insidious manner.

The appearance of an incisional hernia may or may not coincide with heavy lifting or abdominal straining.

In general, the mass that protrudes through the incision site can be pushed back into the abdominal cavity with a finger (reducible).
