Final answer:
The suture technique applied when closing the indirect hernia sac is usually a technique called the Purse-string suture.
Step-by-step explanation:
The suture technique applied when closing the indirect hernia sac is usually a technique called the Purse-string suture. This technique involves sewing the edges of the hernia sac together in order to create a circular shape, resembling a purse string. By doing so, it effectively closes off the opening of the hernia sac and prevents the risk of a recurrent hernia.
For example, let's say a patient has an indirect hernia and undergoes a herniorrhaphy procedure. The surgeon would identify the hernia sac and use a specialized needle and suture material to perform a purse-string suture technique to close the sac.
