A modification of the Cherney incision in gynaecological oncology surgery

Gynaecological oncologists have traditionally used midline vertical or Maylard transverse muscle splitting (Maylard 1907) incisions for their abdomino-pelvic operative procedures (Cavanagh et al. 1985; Kayser et al. 1985). The widespread use of synthetic suture materials has resulted in a reduction in wound dehiscence and hernia with midline incisions, but the vertical scar is a cosmetic disadvantage. With the Maylard incision, suture placement in the transversely incised muscle is difficult and traumatic and the subsequent healing of the muscle incision by fibrosis can result in impaired rectus muscle tone and unsightly bulging at the points of muscle weakness along the wound. Cherney (1941) described an incision which is similar to the Maylard in every way except the tendon, instead of the body, of the rectus muscle is divided. The Cherney incision has many advantages over the musclesplitting incision, including absence of muscle denervation, staggering of the layers of the incision and secure suture placement in tendinous structures. The Cherney peritoneal incision is transverse, and the inferior epigastric vessels are ligated to maximise the width of the incision. The introduction of inferiorly-based rectus abdominis musculocutaneous flaps in gynaecological cancer surgery (Tobin & Day 1988) inspired the development of the following variation in the Cherney incision in which the inferior epigastric vessels are always preserved.
