[SP4]No cut video: 肛門科の基本手術術式：痔核結紮切除術と痔瘻瘻管開放術
岡本 欣也 (東京山手メディカルセンター大腸肛門病センター)
No-cut surgical videos allow clear demonstration of fundamental procedures in proctology. This presentation features two standard operations: hemorrhoidectomy by ligation and excision for hemorrhoids, and fistulotomy for anal fistula. Both remain essential treatments for common anorectal disorders, despite new minimally invasive options. Step-by-step footage highlights patient positioning, anatomical landmarks, dissection, and hemostasis. Technical refinements for the prevention of postoperative bleeding, reduction of pain, and minimization of recurrence are emphasized. In the fistulotomy video, principles of tract identification, secure opening, and creation of an appropriate drainage wound are demonstrated. By presenting unedited surgical videos, this session provides trainees and surgeons with practical insights into reliable operative strategies for daily proctologic practice.
