1. EA法は痔核切除とジオン注射を組み合わせた術式(下図)で,国内における痔核(いぼ痔)の標準的手術です.当院でのEA法の5年累積無再発率(5年間再発しない確率)は92.5%,10年累積無再発率は67.2%です.手術後の合併症は3.5%の症例に認められています(発熱1.7%,出血0.9%,肛門周囲膿瘍0.4%など).

  1. ALTA単独療法(切らずに治すジオン注射療法)の3年累積無再発率は92.6%,6年累積無再発率は72.8%です.手術後の合併症は3.0%の症例に認められています(発熱1.4%,直腸潰瘍0.9%,直腸狭窄0.4%,肛門周囲膿瘍0.3%).

  1. 用手肛門拡張術は裂肛(切れ痔)に対する当院の標準的手術です.3年累積無再発率は87.9%,5年累積無再発率は69.2%です.術後合併症の発生頻度は2.1%です(血栓性外痔核1.3%,肛門皮垂の腫れ0.8%).

  1. 開放式瘻管切除+括約筋固定術は痔瘻に対する当院の標準的手術です.再発率は3%,治癒遷延(治りが遅い)率は1.5%です.一般に痔瘻の手術は便失禁のリスクを伴いますが,当院では図のように肛門括約筋を形成することによって,肛門機能が悪化するのを防いでいます.

  1. ALTA硬化療法+肛門縫縮術は高齢者の直腸脱に対する当院の標準的手術です.3年累積無再発率は78.7%,5年累積無再発率は61.4%です.術後合併症の発生頻度は25.5%で,一時的な排便困難(11.3%),創部の感染(8.4%),補綴材の露出(2.8%)などが主な合併症です.
