Abstract
Background and Objectives: We investigated the effects of using a BiZact™ device for tonsillectomy on operating time, intraoperative blood loss, postoperative bleeding rate, and pain through a meta-analysis of the relevant literature. Materials and Methods: We reviewed studies retrieved from the databases of PubMed, SCOPUS, Google Scholar, Embase, Web of Science, and Cochrane up to March 2024. The results were analyzed following PRISMA guidelines. Six studies that compared the outcomes of patients receiving perioperative BiZact™ tonsillectomy with those in control groups (cold steel dissection or bipolar tonsillectomy) were included for this analysis of the outcomes, which included intraoperative bleeding and time, postoperative pain, and frequency of postoperative bleeding. Results: The operative time (SMD -11.5985, 95%CI [-20.3326; -2.8644], I(2) = 99.5%) in the treatment group was significantly reduced compared to the control group. However, BiZact™ showed no significant efficacy in reducing intraoperative bleeding when compared with the control group (SMD -0.0480, 95%CI [-1.8200; 1.7240], I(2) = 98.6%). Postoperative pain on day 1 (SMD -0.0885, 95%CI [-0.4368; 0.2598], I(2) = 98.9%), day 3 (SMD -0.2118, 95%CI [-0.6110; 0.1873], I(2) = 99.5%), and later than day 7 (SMD 0.0924, 95%CI [-0.2491; 0.4338], I(2) = 98.6%) in the treatment group was not significantly reduced relative to the control group. When compared to the control group, BiZact™ did not reduce the incidence of secondary postoperative bleeding control in the operation room (OR 0.5711, 95%CI [0.2476; 1.3173], I(2) = 32.1%), primary bleeding (OR 0.4514, 95%CI [0.0568; 3.5894], I(2) = 0.0%), or all postoperative bleeding events (OR 0.8117, 95%CI [0.5796; 1.1368], I(2) = 26.3%). Conclusions: This study demonstrated that using the BiZact™ device for tonsillectomy significantly decreased the operative time but could not effectively reduce intraoperative bleeding or postoperative pain and bleeding.
