title: Post-tonsillectomy hemorrhage--some facts will never change.
abstract: Bleeding remains the most significant complication following tonsillectomy (TE), sometimes requiring revision surgery under general anesthesia. This study was undertaken to verify whether or not bleeding rates changed after bipolar coagulation was replaced by suture ligation to achieve hemostasis at a single institution. The charts of all patients who had undergone tonsillectomy between April 1, 2007, and April 30, 2013, at our institution were reviewed. The tonsils were bluntly dissected with scissors and a rasp. While hemostasis was achieved with bipolar coagulation during the first 36 months (group A), this method was replaced after a transition period of 1 month by intraoperative suture ligation (group B) during the last 36 months. Group A encompassed 2,137 patients including 963 children scheduled for adenotonsillectomy (ATE), and group B consisted of 1,521 patients and included 435 ATE cases. Bleeding from the tonsillar wounds occurred in 111/2,137 group A (5.2 %) and 68/1,521 group B patients (4.5 %). The difference was not found to be significant (p = 0.317). The incidence of primary bleeding (PB) and secondary bleeding (SB) was significantly (p = 0,000) associated with the method to achieve hemostasis: PB prevailed in group B and SB prevailed in group A. The overall incidence of post-tonsillectomy hemorrhage (PTH) varied at different ages, but the difference was not significant in group A (p = 0.401) and group B (p = 0.661). Repeated episodes of PTH occurred in 11/111 group A (9.9 %) and 8/68 group B (11.7 %) patients. The statistical difference was not found to be significant (p = 0.725). However, there were significantly more male patients with bleeding complications in both groups. Despite the strongest efforts to avoid it, the potential risk of PTH remains a fact to be accepted by surgeons and patients. An increased surgical precision achieved by introduction of a surgical microscope as well as replacing bipolar cautery by suture ligation to achieve hemostasis could only reduce the overall rate of PTH. Another fact remains unchanged: PB occurs predominantly when electrosurgical means are avoided and SB prevails, whenever surgeons use them. We will continue our research on refined methods of cold steel microsurgical TE including suture techniques.
