Modified components separation technique: experience treating large, complex ventral hernias at a University Hospital

Area of Science:

• Abdominal Wall Reconstruction
• Surgical Techniques
• Hernia Repair

Background:

• Large and complex abdominal wall defects present a significant clinical challenge.
• Component separation technique (CST) is a recognized method for reconstructing these defects.
• Restoring innervated muscle function without excessive tension is crucial.

Purpose of the Study:

• To evaluate the outcomes of a modified CST in treating large ventral hernias.
• To demonstrate the efficacy of the modified technique in complex cases.
• To assess morbidity and recurrence rates associated with the modified CST.

Main Methods:

• A retrospective analysis of 351 patients with complex ventral hernias treated over 10 years.
• All hernias classified as W3 according to EHS criteria.
• Pre- and postoperative CT scans were utilized for assessment.

Main Results:

• The study included 351 patients, with a mean age of 51.6 years and BMI of 32.3.
• Preoperative botulinum toxin and progressive pneumoperitoneum were used in 45 patients with giant defects.
• Postoperative complications included seroma (35.1%), hematoma (9.1%), infection (7.2%), and wound necrosis (8.8%). Hernia recurrence rate was 8.2%.

Conclusions:

• The modified CST is a highly effective strategy for managing complex ventral hernias.
• This technique facilitates primary fascial closure.
• Low rates of morbidity and hernia recurrence were observed.
