Abstract

We retrospectively studied 136 patients who had free flap reconstruction for cancer of the head and neck at a single centre (2008–2015) to evaluate complications, assess factors associated with them, and analyse their impact on outcome. Preoperative and perioperative data, and surgical and medical complications were recorded, and the impact of the complications on duration of hospital stay and survival were assessed. A total of 86 (63%) patients had complications. Compared with those who did not, they had a higher rate of alcohol abuse (21/86, compared with 5/50, p = 0.039), longer operations (median (IQR) 565 (458–653 compared with 479 (418–556) minutes, p < 0.001), and greater intraoperative loss of blood (725 (400–1150) compared with 525 (300–800) ml, p = 0.042). Complications were more common in patients who had fibular flaps and T4 disease (22/86 compared with 4/50, p = 0.010; 47/80 compared with 16/47, p = 0.015, respectively). Those who had complications also stayed in hospital longer (median (IQR) 9 (7–12) compared with 15 (10–21) days, p < 0.001). Cumulative mortality was higher in patients with late complications (those that occurred after the fourth postoperative day) (61% compared with 36%, p = 0.004). In conclusion, complications in more than half the patients were related to alcohol abuse, a more complicated intraoperative course, and fibular flaps. Complications were associated with a longer hospital stay, and survival was higher in those who did not have late complications than in those who did.
