Standard doses of Triamcinolone do not affect fibroblast cell migration of abdominoplasty patients in-vitro1.

BACKGROUND: Recent studies have demonstrated that local application of corticosteroids reduces wound exudation following abdominoplasty and other reconstructive surgical procedures. On the other hand, corticosteroids might provoke wound healing disturbances due to their immunosuppressive effects. OBJECTIVE: The main objective of this study was to gain further information about the impact of the corticosteroid triamcinolone on cell migration in abdominoplasty patients. METHODS: An in-vitro scratch assay wound healing model was applied to observe cell migration of fibroblasts cultured with nutrient medium containing human seroma aspirate±triamcinolone. RESULTS: There were no significant differences regarding cell migration when fibroblasts were incubated with triamcinolone + seroma containing culture medium compared to seroma containing culture medium without triamcinolone. CONCLUSIONS: The performed in-vitro study suggests that triamcinolone does not decelerate fibroblast cell migration which is considered as a surrogate of wound healing.

Do-It-Yourself Preoperative High-Resolution Ultrasound-Guided Flap Design of the Superficial Circumflex Iliac Artery Perforator Flap (SCIP).

The superficial circumflex iliac artery perforator (SCIP) flap is a well-documented, thin, free tissue flap with a minimal donor site morbidity, and has the potential to become the new method for resurfacing moderate-size skin defects. The aim of this study is to describe an easy, reliable, systematic, and standardized approach for preoperative SCIP flap design and perforator characterization, using color-coded duplex sonography (CCDS). A list of customized settings and a straightforward algorithm are presented, which are easily applied by an operator with minimal experience. Specific settings for SCIP flap perforator evaluation were investigated and tested on 12 patients. Deep and superficial superficial circumflex iliac artery (SCIA) branches, along with their corresponding perforators and cutaneous veins, were marked individually with a permanent marker and the anatomy was verified intraoperatively. From this, a simplified procedure for preoperative flap design of the SCIP flap was developed. Branches could be localized and evaluated in all patients. A preoperative structured procedure for ultrasonically guided flap design of the SCIP flap is described. A 100% correlation between the number and emergence points of the branches detected by preoperative CCDS mapping and the intraoperative anatomy was found.
