title: How to avoid pectus bar dislocation in the MIRPE or MOVARPE technique: results of 12 years' experience.
abstract: Bar displacement remains the most common complication of the minimally invasive repair of pectus excavatum (MIRPE). To date, no studies show results from 12 years' experience using a bar fixation technique with only absorbable sutures. Our aim is to show how to stabilize the bar using a modified approach for bar fixation. A retrospective review of 68 patients, who underwent MIRPE or the minor open videoendoscopic assisted repair of pectus excavatum, was performed. To stabilize the pectus bar, both wings of the pectus bar were tied to the ribs in 52 patients with circumcostal absorbable sutures using a Deschamps needle under endoscopic survey and in 16 patients with lateral stabilizers. The stability of pectus bar after the operation was assessed by lateral chest X-ray films and classified as being perfect, incomplete, or poor. No complications were observed in the perioperative period with the circumcostal suture technique. Lateral chest X-rays showed an excellent position of the pectus bar in 50 patients, incomplete position in 1, and poor position in another patient. Our technique seems to be effective in preventing bar displacement following pectus excavatum repair. It does not add any significant cost or time to the operation, and it is fairly simple to perform.
