The purpose of this scientific study is to evaluate the effectiveness of intraoperative luminescence spectroscopy in reducing the incidence of postoperative complications after abdominoplasty in patients with diabetes mellitus. In the main (experimental) group, the mobilization of the skin-fat flap was performed under the control of luminescence spectroscopy to assess tissue viability, while in the control group, the standard method was used. Intraoperative parameters were evaluated, and in the postoperative period, the area of purulent wounds, the volume of lymphorrhea, indicators of systemic inflammation (leukocytes, C-reactive protein, procalcitonin), and the frequency of complications were recorded. The area of the mobilized flap in the experimental group was significantly smaller (456.6 ± 12.8 cm2 vs. 617.6 ± 13.8 cm2). The incidence of purulent complications in the control group was 24.1% versus 19.0% in the experimental group. On day 7, the area of purulent wounds in the control group reached 98.6±7.8 cm2, and by day 14 it increased to 187.5±6.8 cm2, while in the experimental group it was 16.8 ± 1.9 cm2 and did not progress. Indicators of systemic inflammation and procalcitonin levels were significantly lower in the main group. Using spectroscopy, the group also had decreased drainage discharge volume and drainage removal timing. Thus, the use of intraoperative luminescent spectroscopy for abdominoplasty in patients with diabetes mellitus allows an objective assessment of tissue viability, reduces the volume of excision, and significantly reduces the risk of postoperative purulent complications.
