[Original pericostal suture sparing the neurovascular bundle for prevention of post-thoracotomy pain syndrome after video-assisted mini-thoracotomy].

Abstract

Objective: To prevent post-thoracotomy pain syndrome and its consequences after video-assisted mini-thoracotomy using original pericostal suture sparing the neurovascular bundle.

Material and methods: Original pericostal suture sparing the neurovascular bundle was developed to prevent post-thoracotomy pain syndrome. A prospective cohort controlled randomized clinical trial with 2-month follow-up was conducted to estimate postoperative pain syndrome after various pericostal sutures. The study included 71 patients who underwent video-assisted atypical lung resections for various lung diseases (29 women and 42 men aged 41.2 ±5.1 years). All patients were divided into 2 groups: group I - standard pericostal suture; group II - original pericostal suture sparing the neurovascular bundle.

Results: Intensity of pain after 1-2 postoperative days was higher by 43.2% in the 1^st group, at discharge - by 85.8%. Mean area of paresthesia was less by 39.7% after 1 postoperative month and by 28.8% after 2 months in the 2^nd group.

Conclusion: Original pericostal suture with subperiosteal canal through detachment of neurovascular bundle from the underlying rib reduces the incidence of post-thoracotomy pain syndrome.
