a purse-string suture is a specialized surgical technique used to close circular or oval-shaped wounds or incisions. It involves placing a suture in a circular pattern around the wound, resembling the tightening of a drawstring on a purse. The suture gathers the tissue together, creating a tight and uniform closure to minimize the risk of leakage or infection. This technique is commonly used in surgeries involving hollow organs or structures to achieve a watertight and secure closure.
