Minimally invasive repair for treating pectus excavatum--early results

Minimally invasive repair of pectus excavatum (MIRPE) is the preferred technique for repair of funnel chest deformity. The aim of this study is to evaluate our initial postoperative results, to identify factors related to postoperative complications and to examine the acceptability of MIRPE by the patients.

25 MIRPE patients (20 male and 5 female) were operated on between November 2002 and February 2007 at the Department of Pediatric Surgery, Turku University Central Hospital. The median age of the patients was 14 years (range from 5 to 23 years). One patient had undergone previously open Sulamaa reconstruction and one had a history of intrathoracic lymphoma. The remaining 23 patients had primary pectus excavatum. A right thoracoscopy was performed to every patient.

Operative mortality was zero and there were no clinically significant bleeding complications. Epidural analgesia was necessary for adequate pain control. Small symptomless residual pneumothoraxes and pleural effusions were common after the operation but neither required intervention. One patient had a hemothorax 7 months postoperatively, which was cured with a single puncture. Bar displacement took place in 2 patients but required correction in only one of these patients. There were 2 wound infections, one superficial and one which led to removal of the bar was 6 months after the operation. This may have been unnecessary. Two patients had pneumonia, one probably unrelated to the operation. One patient required psychiatric ward treatment, and 3 patients had mild psychological symptoms not requiring specific therapy. The preliminary cosmetic results were good or excellent in 90% of the cases, but a longer follow-up is needed for information on the final outcome.

MIRPE is a safe operation and gives a cosmetically good result. Thoracoscopy is needed during the operation. The early postoperative period in hospital is painful and there the patients need intensive care. We found the high epidural analgesia beneficial and safe during early period of pain treatment. The bar is removed not earlier than 3 years after the operation as a day care surgical procedure.
