Abdominal Wall Partitioning (the Accordion Effect) for Reconstruction of Major Defects: A Retrospective Review of 10 Patients

Ten patients underwent abdominal wall reconstruction using the technique of abdominal wall partitioning. All defects were closed in the midline by approximating fascia to fascia with the assistance of a general surgeon. One patient had skin grafted small bowel. Five patients had chronically infected mesh and previous failed attempts at repair. Four patients had large ventral hernias following gastric reduction operations and massive weight loss. No defect in any dimension was less than 20 cm. All patients had secure abdominal wall repair by reconstruction of a midline anchor for the abdominal wall musculature. One patient was lost to follow-up after 3 weeks. The average follow-up time for the remaining nine patients was 18.6 months (range, 6 months to 4.7 years). One patient required readmission to the hospital for management of a limited area of skin necrosis. Two patients had minor wound infections, and three patients had subcutaneous seromas, all of which were managed on an outpatient basis. One patient developed a 2 × 2-cm subxiphoid hernia recurrence. Technical details include subcutaneous undermining of the abdominal skin to the anterior axillary lines bilaterally, mobilization of the viscera to expose the white lines of Toldt bilaterally, and parallel, parasagittal, staggered releases of the transversalis fascia, transversalis muscle, external oblique fascia, external oblique muscle, and rectus fascia. These multiple releases allow expansion and translation of the abdominal wall by an accordion-like effect. This accordion-like effect allows closure of abdominal wall defects that are substantially larger than what can be closed with current techniques. (Plast. Reconstr. Surg. 112: 477. 2003.)
