[Method of repair of anterior abdominal wall defects in children]
Insights
This study on pediatric ventral hernias found that using two to three rows of crimping sutures significantly reduces tension on abdominal wall defect edges. This technique enables tension-free closure, improving surgical outcomes in children.
Area of Science:
- Pediatric Surgery
- Abdominal Wall Reconstruction
- Biomechanical Engineering
Context:
- Ventral hernias in children pose surgical challenges due to abdominal wall tension.
- Current plasty methods may involve significant stress on wound edges.
- Cadaveric models are crucial for biomechanical analysis of surgical techniques.
Purpose:
- To evaluate the biomechanical effectiveness of crimping sutures in reducing tension on abdominal wall defects.
- To determine optimal suture placement for tension reduction.
- To develop and clinically validate a novel autoplasty technique for pediatric ventral hernias.
Summary:
- Experimental studies on 60 pediatric cadavers simulated ventral defects (6-10 cm) in the anterior abdominal wall.
- Crimping sutures applied to the rectus abdominis aponeurosis were tested using a tensiometric device to measure edge stretching force.
- Two to three rows of sutures effectively decreased tension, allowing tension-free closure and identification of optimal suture zones.
Impact:
- Development of a clinically successful autoplasty method for pediatric ventral hernias, utilizing preliminary tension removal.
- Successful application of the technique in 9 pediatric patients aged 2 to 14 years.
- Provides a biomechanically sound approach to minimize stress during abdominal wall defect repair in children.
Abstract:
Experimental studies were conducted on 60 cadavers of children whose ages ranged from 0 to 14 years. A defect measuring 6-10 cm was formed in the muscles of the anterior abdominal wall (an approximate model of a hiatal opening). Several rows of crimping sutures were then applied to the aponeurosis of the rectus abdominis muscle above and below the defect. The force of stretching of the edges of the defect was studied by an elaborated tensiometric device after application of each row of crimping sutures. It was found that application of two or three rows of crimping sutures above and below the ventral defect ensures reliable decrease of the stretching load exerted on its edges and allows them to be sutured without tension. The optimal zones in the operative field for applying the crimping sutures were also determined. On the basis of experimental study the authors developed and used in the clinic a method for autoplasty of ventral hernias based principally on placing sutures through the edges of the ventral defect only after their approximation, after preliminary removal of the stretching load experienced by the laparotomic wound. The authors used this method of plasty successfully in 9 children with ventral hernias whose ages ranged from 2 to 14 years.
