Lateral paramedian incision.
Prospective randomization of 360 patients undergoing abdominal surgery determined whether a standard lateral paramedian incision was made (group A) or one of two modifications in which the anterior sheath was incised medially and posterior sheath incised laterally (group B) or vice versa (group C), in order to determine the necessity for incising both layers laterally to provide the shutter mechanism which is held responsible for the integrity of this wound. Medial incision of the anterior rectus sheath significantly reduced the time required to perform the incision (P less than 0.02) and tended to reduce wound sepsis rate. However, this was achieved at the cost of a higher incisional hernia rate (0 per cent, 2.9 per cent and 4.6 per cent in groups A, B and C respectively, P less than 0.02). We conclude that lateral incision of both anterior and posterior rectus sheath is necessary to obviate the risk of wound hernia with the lateral paramedian incision.
