The design of a modified needle for trephine biopsy in rectal cancer recurrence in the perineal region is described. The needle design is simple and can be readily manufactured in a mechanic shop. The biopsy material obtained is large enough to type the tumor histologically. The technic of biopsy is not complicated and requires no special skill. Trephine-biopsy for rectal cancer recurrences may substitute completely knife biopsy, being a safe maneuvre in the complex diagnosis of rectal cancer recurrence.
本文描述了一种用于会阴区直肠癌复发环钻活检的改良针的设计。该针的设计简单，可在机械车间轻松制造。所获取的活检材料足够大，能够进行肿瘤组织学分型。活检技术并不复杂，不需要特殊技能。对于直肠癌复发的环钻活检可以完全替代刀割活检，是直肠癌复发复杂诊断中的一种安全操作。
