RESPIRATORY FUNCTION AND ENDOSCOPIC SCOLIOSIS SURGERY



Abstract

INTRODUCTION: Endoscopic techniques are an established technique for anterior correction and instrumentation of thoracic scoliosis. Deterioration in respiratory function post thoracotomy has been cited as a disadvantage of anterior approaches and led certain authors to recommend posterior methods1. Endoscopic techniques may reduce respiratory complications and respiratory compromise in both the short and long term.

METHODS: Thirty eight patients, seven male 31 female, mean age 17.3 years (11– 37 years) have undergone endoscopic scoliosis surgery under the senior author. Indication for surgery was idiopathic scoliosis 36 and an underlying syrinx 2. All patients undergoing endoscopic scoliosis surgery have a standard pre-operative assessment including respiratory function tests (RFTs). All patients have been followed up prospectively (mean 15 months, range 3 – 33 months) and standard data recorded. As part of this study we are in the process of performing follow up RFTs on all patients.

RESULTS: Pre-operatively no significant respiratory function compromise attributable to the scoliosis has been detected. Mean duration of intercostal drain was two days, one patient requiring reinsertion for a recurrent pneumothorax. No other major respiratory complication occurred. On average patients were fully mobile by day five and mean hospital stay was six days (4–10 days). Provisional RFTs post-operatively have shown no significant change.

DISCUSSION: Our provisional results indicate that endoscopic scoliosis correction and instrumentation do not lead to early respiratory complications or to a significant deterioration in respiratory function of the patient.
