The adhesion barrier of the medical anti-adhesion membrane is a medical implant that can be used to reduce abnormal internal scars by separating internal tissues and organs, thereby preventing them from sticking together.
Surgeons have realized that proper surgical techniques are essential to reduce adhesion formation. In addition, for more than a century, adjuvants including materials such as drugs and animal membranes, gold foil, mineral oil, rubber, and Teflon sheets have been used to reduce the risk of adhesion formation. Nevertheless, adhesions do occur, and to some extent seem to be an almost inevitable consequence of abdominal and pelvic surgery. Adhesion can cause serious postoperative complications, intestinal obstruction, infertility and chronic pelvic pain or chronic abdominal pain.

Surgeons and healthcare professionals have developed a variety of methods to reduce tissue damage and minimize the formation of adhesions. However, even an experienced surgeon, despite the use of advanced technology, may not be able to completely prevent the formation of postoperative adhesions without the help of medical anti-adhesion membranes. Therefore, many surgeons use medical anti-adhesion membranes when performing abdominal and pelvic surgery.
However, a study found that the frequency of use of adhesion barriers is very low. The study examined hospital data and found that medical anti-adhesion membranes are only used in more than 5% of procedures, and the use of barriers is appropriate.
Advantages of medical anti-adhesion film:
1. Customizable characteristics, such as thickness, dissolution rate, texture and tensile strength
2. Provide a concentrated dose of reagent or therapy in a uniform film coating
3. The dry film form improves the stability of reagents/active ingredients
4. Compared with other dispensing techniques (such as spraying), reagents/active ingredients can be used more effectively
5. Provide separation of reagent/active ingredient components
