Summary
Surgical sponges do not cause peritoneal adhesions; abrasive trauma does. Intestinal motility may prevent adhesions by reducing early postoperative inflammation and trauma.
Area of Science:
- Surgical pathology
- Inflammatory response
- Abdominal surgery
Background:
- Peritoneal adhesions are a significant complication of abdominal surgery.
- The role of foreign debris from surgical sponges in adhesion formation has been debated.
Purpose of the Study:
- To investigate the cause of peritoneal adhesions following the use of surgical sponges.
- To identify factors influencing the prevention of peritoneal adhesions.
Main Methods:
- Experiments were conducted using Porton rats.
- Surgical sponges were introduced into the peritoneal cavity.
- Mesothelial trauma and subsequent inflammatory responses were analyzed.
- Adhesion formation was compared between mobile and non-mobile peritoneal surfaces.
Main Results:
- Foreign debris from surgical sponges did not cause peritoneal adhesions.
- The abrasive action of sponge insertion caused mesothelial trauma, initiating inflammation.
- Adhesions formed on traumatized, non-mobile peritoneal surfaces.
- Adhesions did not form on mobile intra-abdominal viscera.
Conclusions:
- Mesothelial trauma, not sponge debris, is the primary cause of peritoneal adhesions.
- Intestinal motility in the early postoperative period is crucial for preventing adhesion formation.
