Drain-free donor site in Deep Inferior Epigastric Perforator free flap: A single-surgeon experience

Donor-site seroma and wound dehiscence in Deep Inferior Epigastric Perforator (DIEP) free flaps can be problematic. The value of donor-site drains is debated, with alternative closure techniques demonstrating good outcomes. However, no literature exists on patient outcomes in which no drain or dead space reduction technique is used. The senior author of this paper has opted for a drain-free, simple layered closure without adjuncts since 2016. We evaluate the outcomes of this technique against the literature. A single-center, single-surgeon, prospective study of all DIEP flap breast reconstruction between January 2016 and March 2020, whereby the donor site was closed without drains or alternative dead space reduction measures. One hundred and thirty-eight patients with a mean age of 50.72±9.16 (range 26-73) underwent DIEP breast reconstruction (78% unilateral (n = 107), 22% bilateral (n = 31). The incidence of drain-free specific donor-site complications was 9.4%, with wound breakdown being the most common (9/138, 6.5%). However, only one patient required secondary closure. The average length of hospital stay was 4.2±1 days (range 2-9). Abdominal drains may serve as a psychological barrier for patients in expediting discharge and can be painful and cumbersome. This translates into significant cost implications. Evidence suggests that superior outcomes are achieved when dead space-reducing adjuncts rather than drains are used. However, our data suggest that DIEP donor sites can also be safely closed without these adjuncts, which may unnecessarily lengthen procedure time, consume more resources, and increase localized foreign body tissue reactions, without good indication.
