Papers・Description	OBJECTIVES: To identify the risk factors for post-tonsillectomy hemorrhage (PTH) in adult patients (>19 years). METHODS: 275 adult patients who underwent tonsillectomy between 2009 and 2019 were retrospectively analyzed. Possible risk factors associated with PTH were investigated by univariate and multivariate logistic regression analyses. RESULTS: PTH occurred in 39 of 275 patients (14.2%). Regarding underlying diseases, PTH occurred more frequently in focal infection of IgA nephropathy. Furthermore, bipolar electrocautery was the other risk factor for PTH on multivariate analysis. CONCLUSION: Focal infection of IgA nephropathy and bipolar electrocautery were identified as the risk factors for PTH.
