Percutaneous expansion technique for preperitoneal mesh repair in hernias of the lateral aspect of the anterior abdominal wall by using 2 tip hole needles.

Preperitoneal mesh repair is associated with good results in hernia repairs of the lateral aspect of the anterior abdominal wall, but this is difficult, and needs much subcutaneous dissection. The percutaneous expansion technique was used to produce well-expanded and fixed mesh at the preperitoneal plane without much dissection. This study included 40 patients who have hernias at the lateral aspect of the anterior abdominal wall. This technique was used to expand and fix the mesh at the preperitoneal plane by helping 2 tip hole needles through multiple small wounds in the anterior abdominal wall. There was no recurrence during the period of follow up. One patient developed subcutaneous seroma collection after 1 month of operation. This percutaneous expansion technique is novel, simple, and easy, and it is associated with good results in the repair of hernias of the lateral aspect of the anterior abdominal wall.
