Summary:
To minimize donor-site damage, robot-assisted (RA) deep inferior epigastric perforator (DIEP) flap harvest has been suggested. Current robotic approaches favor port placement, which either does not allow a bilateral DIEP flap harvest through the same ports or necessitates additional scars. In this article, the authors propose a modification of port configuration. In a retrospective controlled cohort study, RA-DIEP and conventional DIEP surgery were compared. The perforator and pedicle were visualized conventionally until the level behind the rectus abdominis muscle. Next, the robotic system was installed to dissect the retromuscular pedicle. The authors assessed patient age; body mass index; history of smoking, diabetes mellitus, and hypertension; and additional surgical time. The length of the anterior rectus sheath (ARS) incision was measured. Pain was quantified using the visual analogue scale. Donor-site complications were assessed. Thirteen RA-DIEP flaps (11 unilateral and two bilateral) and 87 conventional DIEP flaps were harvested without flap loss. The bilateral DIEP flaps were raised without readjustments of the ports. The mean time for pedicle dissection was 53.2 ± 13.4 minutes. The length of the ARS incision was significantly shorter in the RA-DIEP group (2.67 ± 1.13 cm versus 8.14 ± 1.69 cm; 304.87% difference; P < 0.0001). There was no statistical difference in postoperative pain (day 1: 1.9 ± 0.9 versus 2.9 ± 1.6, P = 0.094; day 2: 1.8 ± 1.2 versus 2.3 ± 1.5, P = 0.319; day 3: 1.6 ± 0.9 versus 2.0 ± 1.3, P = 0.444). Preliminary results show that the authors’ RA-DIEP approach is safe and allows dissection of bilateral RA-DIEP flaps with short ARS incision lengths.
