肠息肉是一种常见病,多发生于直肠与乙状结肠。常引起出血,有的可发生癌变。以往对低位直肠带蒂息肉,是将息肉拉出肛门以丝线贯穿结扎其蒂部;或用手指将其蒂部捏断。手术较为简单。但对直肠中后部息肉采用电灼术,技术不易掌握,对位置较高的直肠息肉及乙状结肠息肉采用经腹腔切开 Intestinal polyps are a common disease that occurs most often in the rectum and sigmoid colon. Causes bleeding, and some may develop cancer. In the past, the polyps on the lower rectum were pulled out of the anus with silk thread to ligate the pedicle, or the pedicle was pinched with fingers.
