Abstract
INTRODUCTION Seroma is a frequent complication that can affect the final result of reconstructive and cosmetic surgeries. METHODOLOGY This study evaluated the effectiveness of 5-Fluorouracil and 75% hypertonic glucose in preventing seroma in a mastectomy rat model, as well as cellular and vascular events in adjacent tissues. A left mastectomy with lymphadenectomy was performed in 60 Wistar-Albino female rats. Animals randomly allocated to the control group (Group I; n = 20) were sutured right after mastectomy. The intervention groups received 1.0 mL of 75% hypertonic glucose (Group II; n = 20) or 1.0 mL of 5-Fluorouracil (Group III; n = 20) at the surgical site before suturing. The assessment of the presence of seroma was performed in all animals at 24, 48, and 72 h and on the 7th and 12th postoperative day. After the 12th day, a tissue sample was taken from the surgical site and sent for histological analysis. The occurrence of seroma was assessed using GEE. A significance level of 5% was adopted. RESULTS Differences in seroma formation over time were observed for both Control Group I (p=0.041) and Intervention Group II (p<0.001). In Intervention Group III, there was no difference in the percentage and volume of seroma across the assessment points (p=0.627). When both the Control and Intervention Group II were compared to Intervention Group III, we found a reduction in seroma formation in the last group. The reduction in the inflammatory process was more regular to Intervention Group III. CONCLUSION In this animal model, 5-Fluorouracil was more effective in preventing seroma formation than 75% Hypertonic Glucose.
