Purse-string suture

Purse-string suture is a type of suture used in surgery to close circular wounds. It is named for its resemblance to the drawstring or "purse string" used to close bags or purses.

History

The purse-string suture has been used in surgical procedures for centuries. Its earliest recorded use dates back to the Roman era, where it was used in the treatment of abdominal and chest wounds.

Technique

The purse-string suture is typically used to close circular or tube-like structures in the body. The suture is placed in a circular pattern around the edge of the wound. Once the suture is in place, the ends are pulled tight, causing the wound to close in a manner similar to a drawstring bag. This technique is often used in gastrointestinal surgery, cardiac surgery, and colorectal surgery.

Applications

Purse-string sutures are commonly used in a variety of surgical procedures. In appendectomy, the suture is used to close the stump of the appendix. In colostomy and ileostomy, it is used to secure the bowel to the abdominal wall. In cardiac surgery, it is used to close the openings made for cardiopulmonary bypass.

Advantages and Disadvantages

The purse-string suture offers several advantages over other types of sutures. It provides a secure closure, reduces the risk of infection, and promotes healing by bringing the edges of the wound together. However, it also has some disadvantages. It can be difficult to place, especially in deep or narrow wounds, and it may cause constriction or narrowing of the structure it is used to close.
