Abstract
BACKGROUND: Quilting, a technique in which skin flaps are sutured to the underlying muscle, reduces seroma after mastectomy and/or axillary lymph node dissection. The aim of this study was to assess the effect of different quilting techniques on the formation of clinically significant seroma. METHODS: This was a retrospective study including patients undergoing mastectomy and/or axillary lymph node dissection. Four breast surgeons applied the quilting technique based on their own discretion. Technique 1 was performed using Stratafix in 5-7 rows placed at 2-3 cm distance. Technique 2 was performed using Vicryl 2-0 in 4-8 rows placed at 1.5-2 cm distance. Technique 3 was performed using Vicryl 0/1 in 3 rows placed at 3-4 cm distance. Technique 4 was performed using Vicryl 0 in 4-5 rows placed at 1.5 cm distance. The primary outcome was clinically significant seroma. RESULTS: A total of 445 patients were included. Clinically significant seroma incidence was 4.1 per cent (six of 147) for technique 1, which was significantly lower than that for the other techniques (25.0 per cent (29 of 116), 29.4 per cent (32 of 109), and 33 per cent (24 of 73) for techniques 2, 3, and 4 (P < 0.001) respectively). The duration of surgery was not significantly longer for technique 1 compared with the other three techniques. The length of hospital stay, number of additional visits to the outpatient clinic, and reoperations did not differ significantly between the four techniques. CONCLUSION: Quilting using Stratafix and placing 5-7 rows with 2-3 cm distance between the stitches associates with low clinically significant seroma incidence without adverse effects.
