Overview
These hernias present as a bulge or protrusion at or near the area of the prior incision scar. Virtually any prior abdominal operation can subsequently develop an Incisional Hernia at the scar area, including those from large abdominal procedures (intestinal surgery, vascular surgery), to small incisions (Appendectomy, or Laparoscopy). These hernias can occur at any incision, but tend to occur more commonly along a straight line from the breastbone straight down to the pubis, and are more complex in these regions.
Causes
- Infection - Cases operated for peritonitis such as perforated duodenal ulcer, gangrene of the intestines.
- Anatomical site - The midline of lower abdomen is highly prone, due to absence of posterior rectus sheath below the arcuate line.
- Obesity with weak muscular tone.
- Faulty sutures
- Faulty technique of closure of the abdomen.
- Ascites
- Wrongly placed incisions tampering the nerves.
- Persistent postoperative cough.
