作者在直肠息肉摘除术能改善症状的启示下,对7例20～23岁男性患者进行多次内窥镜下电外科息肉摘除术和术后观察。患者均经反复血吸虫病治疗而仍有直肠出血和经常腹泻。血吸虫性息肉是经直肠检查、乙状结肠镜检和3次直肠活检、双重对比钡剂灌肠、结肠内窥镜和大便找到血吸虫卵而确诊者。经内窥镜观察,息肉主要位于直肠和乙状结肠,少数位于降结肠而偶见于横结肠和升结肠。术中对直径大于5cm的息肉尽量予以摘除。7例中4例的息肉于1次内窥镜下全部摘除,余3例进行2～3次。采用该法可在1小时内摘除上百个息肉。7例中2例因术后出血而留院观察24小时以上,1例输
Based on the enlightenment of rectal polypectomy to improve symptoms, the author performed multiple endoscopic electrosurgical polypectomy and postoperative observation on 7 male patients aged 20-23 years. All patients were treated with repeated schistosomiasis and there was still rectal bleeding and frequent diarrhea. Schistosome-like polyps were diagnosed by rectal examination, sigmoidoscopy, and 3 rectal biopsies, double contrast barium enema, colon endoscopy, and stool to find schistosome eggs. After endoscopic observation, polyps are mainly located in the rectum and sigmoid colon, a few in the descending colon and occasionally in the transverse colon and ascending colon. Intraoperative removal of polyps larger than 5 cm in diameter is recommended. Of the 7 cases, 4 cases of polyps were all removed under an endoscope, and the remaining 3 cases were performed 2 to 3 times. With this method, hundreds of polyps can be removed within one hour. Two of the 7 patients were admitted to the hospital for more than 24 hours due to postoperative bleeding and 1 patient lost
