The deep inferior epigastric perforator (DIEP) flap is a predominant technique for autologous breast reconstruction. However, the best method of abdominal fascial closure in this technique is not well defined. This study details our initial experience with unidirectional barbed suture-only repair of abdominal donor site fascia. Patients who underwent DIEP flap breast reconstruction and abdominal fascial closure with Stratafix Symmetric Polydioxanone PDS Plus were retrospectively reviewed. Information regarding pertinent patient history, medical comorbidities, risk factors, and surgical technique was extracted, along with the incidence of eight separate postoperative abdominal surgical site occurrences. Retrospective review identified 43 patients who underwent 19 unilateral and 24 bilateral DIEP flap breast reconstruction procedures (n = 67). Average patient follow-up was 791 days (range 153-1769). Six patients (14%) had a complication of the donor site. Seroma was most frequent (n = 3, 7%), followed by surgical site infection (n = 2, 5%). One patient had incisional dehiscence (2%) and another patient developed bulging (2%). No patients had chronic pain, weakness, hematoma, or hernia postoperatively. Patients with donor site complications had a history of abdominal/pelvic surgery significantly more often than the patients without donor site complications (100% versus 49%; = 0.032). Abdominal fascial repair with Stratafix Symmetric suture alone led to low rates of abdominal donor site morbidity, including no hernia and rare bulging, following DIEP flap breast reconstruction. Additional advantages of this technique may be reduced operative times and lower operative costs compared with alternative methods of fascial repair, although prospective and randomized studies are warranted.
