Vacuum-Assisted Closure Versus Graduated Primary Skin Closure for Postoperative Burst Abdomen

Burst abdomen, or complete abdominal wound dehiscence, is a severe postoperative complication characterized by the separation of the musculo-aponeurotic layer of the abdominal wall. It leads to extended hospital stays, high treatment costs, and an increased risk of long-term incisional hernia. While negative pressure wound therapy using vacuum-assisted closure (VAC) is widely utilized, graduated (staged) primary skin closure remains a common, accessible bedside alternative. Direct randomized comparative evidence evaluating these two approaches for established burst abdomen is limited. The main objective of this study is to compare the clinical effectiveness and safety of vacuum-assisted closure (VAC) versus graduated primary skin closure in the management of postoperative burst abdomen. Participants will be randomly assigned (1:1) to one of two groups: 1. VAC Group: Patients will receive continuous negative pressure wound therapy (-75 to -125 mmHg) applied via a specialized polyurethane foam and adhesive dressing, with changes performed every 48 to 72 hours until sufficient granulation tissue forms for definitive closure. 2. Graduated Closure Group: Patients will undergo progressive re-approximation of the wound edges using full-thickness retention sutures placed under local anesthesia and tightened incrementally every 48 to 72 hours until complete closure is achieved. The primary outcome of the study is the time to achieve complete fascial and cutaneous wound closure. Secondary outcomes include total length of hospital stay, incidence of surgical site infections, pain scores during procedures, wound recurrence, and incisional hernia formation during follow-up.

Myriad™ Augmented Soft Tissue Reconstruction Registry

This is an observational study designed to evaluate the safety and clinical outcomes of Myriad™ in soft tissue reconstruction procedures. The study will enroll participants who are undergoing a surgical procedure, where the attending physician will use Myriad™ as part of the surgical intervention.
