Periumbilical Anatomy of Scarpa's Fascia: Rationale Behind a "Modified Scarpa's" Abdominal Closure Technique

Area of Science:

• Plastic Surgery
• Anatomy
• Surgical Techniques

Background:

• Intraoperative observations suggest Scarpa's fascia (SF) is thinner in the periumbilical area.
• Previous studies have not objectively quantified this attenuation.

Purpose of the Study:

• To objectively evaluate Scarpa's fascia (SF) anatomy in the periumbilical region.
• To assess clinical outcomes of a novel, modified SF closure technique for transverse abdominal wall incisions.

Main Methods:

• Retrospective analysis of abdominal MR angiography in 66 patients before autologous breast reconstruction.
• Validation of MR findings with intraoperative measurements from panniculectomy specimens.
• Recording of donor site complications in patients undergoing the modified SF closure.

Main Results:

• Significant attenuation of SF was observed, with an average absence surface area of 56.3 cm².
• SF presentation varied significantly with patient age (P=0.013) and BMI (P=0.005).
• Abdominal closure site complications occurred in 7.6% of patients.

Conclusions:

• The study objectively confirms SF attenuation in the periumbilical region.
• A novel modified SF closure technique is described.
• Evidence supports the adoption of this technique for transverse abdominal wall incisions.
