# The individualized treatment for minimally invasive repair of pectus carinatum in adolescent: a single center’ s retrospective study

## TL;DR

This study examines the effectiveness of individualized minimally invasive surgical treatments for pectus carinatum in adolescents.

## Contribution

The study presents a retrospective analysis of individualized surgical approaches for pectus carinatum with or without pectus excavatum.

## Key findings

- The Abramson procedure alone or combined with the Nuss procedure showed good short-term outcomes for pectus carinatum.
- Procedure selection should be individualized based on the lower plane depression after the Abramson procedure.
- Complications included pneumothorax, overcorrection, and steel wire breakage, but no severe issues occurred.

## Abstract

Pectus carinatum (PC) mainly present at the growth spurt time of the early teenage years or the puberty. Poor outer appearance is a major reason for seeking help for surgeons to increase self-confidence and self-esteem. At present, minimally invasive repair (MIR) is one of effective ways to correct the chest wall deformity. Therefore, there is great practical significance to conduct clinical research on MIR about the adolescent PC.

We applied Abramson procedure in PC group or we applied Abramson procedure and Nuss procedure in PC/PE group. We retrospectively reviewed the results of 41 cases who underwent the surgical correction at our department from January 2020 to April 2023.

All the procedures were successfully done without severe complications. The median operation Time was 80 min in PC group while was 130 min in PC/PE group. The median LOS were 4 days in PC group while 5 days in PC/PE group. The median compression depth was 32 mm in PC group while 12 mm in PC/PE group. Postoperatively, there are some complications. All Pneumothorax patients being treated conservatively were found in 9 patients in two groups. One patient suffered overcorrection after operation. There were 3 patients suffered steel wires breakage in two groups. One patient reoperation postoperatively for the dislocation of the bar secondary to steel wires breakage.

The Abramson procedure or Abramson procedure and Nuss procedure have good short-term results in repair PC and PC/PE. Select one or two procedures should be done individually based on whether the lower plane over depressed after Abramson procedure.
