Applicability of Clavien-Dindo classification in Nuss procedure surgical complications.

OBJECTIVES

Nuss procedure is a safe surgery but not exempt from complications. Clavien-Dindo classification (1992) allows complications of any surgery to be recorded. Our objective was to prove its applicability in the study of Nuss procedure complications.

MATERIAL AND

METHODS

We present a retrospective series of PE patients undergoing surgery from January 2010 to January 2018. Nuss procedure associated morbidity prior to bar removal was studied. Complications were stratified according to Clavien-Dindo classification.

RESULTS

A total of 31 patients were included. Mean age was 14.67 years (4-27 years), with a mean Haller index of 6.06 (3.35-14.14) and a mean correction index of 41.2% (16-87%). Clavien-Dindo classification I-IIIb mild complications were recorded in 35.48% of patients. Seroma was found in 4 patients (12%), of whom 1 had superinfection and 1 had wound dehiscence. In 6 patients, bar and/or stabilizer mobilization was noted, and in 1 patient, postoperative acute pulmonary edema (3%) was observed. Of the 11 patients with complications, only 6 required re-intervention -5 as a result of prosthesis mobilization, and 1 as a result of infection not resolved with intravenous antibiotic therapy.

CONCLUSIONS

Clavien-Dindo classification is being increasingly used as a way of unifying surgical complication criteria by comparing results. Our study demonstrated that such classification is a feasible and reproducible method when it comes to reflecting Nuss procedure morbidity and comparing it with other groups.
