Operative correction of pectus excavatum: an evolving perspective
Insights
This study refined pectus excavatum repair in children, showing a modified Ravitch procedure with internal fixation yields excellent results. Early elective repair (4-6 years) improves outcomes and emotional well-being.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Congenital Abnormalities
Background:
- Pectus excavatum, a congenital chest wall deformity, affects children's physical and emotional health.
- Surgical reconstruction has evolved, with varying techniques and outcomes.
- Previous methods involved prosthetic support, posing risks and necessitating further procedures.
Purpose of the Study:
- To analyze trends in pectus excavatum surgical management from 1949-1975.
- To compare outcomes between historical and recent surgical approaches.
- To evaluate the efficacy of a modified Ravitch repair with internal fixation.
Main Methods:
- Retrospective analysis of 220 pediatric pectus excavatum cases (1949-1975).
- Comparison of 183 historical cases with 45 recent cases undergoing a modified Ravitch repair and internal fixation.
- Evaluation of age distribution, complications, and long-term results.
Main Results:
- Recent cohort (45 children) utilized a modified Ravitch repair with three-point internal fixation, avoiding prosthetic materials.
- Significant trend towards earlier repair, with 80% of recent patients aged 3-8 years (average 5.8 years).
- Reduced blood transfusion rates (10%), near resolution of seromas with suction drains, and 100% excellent/acceptable results in the recent group.
Conclusions:
- A standardized, modified Ravitch repair with internal fixation offers excellent results for pectus excavatum.
- Elective surgical correction between ages 4-6 years is recommended for optimal operative and emotional outcomes.
- Avoiding prosthetic support simplifies the procedure and eliminates risks associated with foreign materials.
Abstract:
From 1949 to 1975, 220 children have undergone surgical reconstruction of pectus excavatum using a variety of operations on our Pediatric Surgical Service. The first 183 were previously reported and have had subsequent, careful followup evaluation. From 1970 to 1975, an identifiable group of 45 children had a standard operation, a modified Ravitch repair, with the addition of a three-point or tripod internal fixation technique for support of the sternum. These children have all obtained satisfactory reconstruction without prosthetic support of any kind. We have thus avoided the possible danger of foreign material within the chest and have obviated the need for another procedure to remove a supporting stent. The two groups have been analyzed and compared with respect to age distribution, postoperative complications and end results to see if we could detect any trends in the evolving management of children with this condition. The main indications for surgical correction remain cosmetic and postural. Specific trends which have emerged from our experience include an increased percentage of patients between 3 and 8 years of age (average 5.8 years); a decreased need for blood transfusion (10%); a near resolution of postoperative seromas with the use of substernal and subcutaneous suction drains; and in the last 45 children, a 100% excellent or acceptable result to date. We feel that age selection is an important factor in the improved operative result and in the emotional impact on these young patients. Eighty per cent of the children in the recent series were between 3 and 8 years of age at the time of repair. On the basis of this experience, we now feel confident in recommending our standardized operation for pectus excavatum at an elective age of 4 to 6 years.
