Herniarrhaphy is a surgical procedure used to repair a hernia, which occurs when an internal organ or tissue protrudes through a weak spot in the abdominal wall. During the procedure, the surgeon typically returns the displaced tissue to its proper position and reinforces the abdominal wall, often using sutures or mesh to prevent recurrence. This operation can be performed through open surgery or minimally invasive techniques, depending on the specific case and the patient's condition.
