The trend in treatment of internal hemorrhoids has migrated from inpatient-surgical to outpatient non surgical with comparable results. A variety of techniques have been developed including banding, injecting, heating, and freezing. Band ligation is a quick, simple and effective method which can be easily applied at the time of colonoscopy. This report is a presentation of results and review of the literature.
ObjectiveTo summarize the research progression of Doppler-guided hemorrhoidal artery ligation in the treatment of hemorrhoids. MethodsThe related literatures in recent years were reviewed, and to investigate the operation principle, operation process, the indications and effects, and existing problems of Doppler-guided hemorrhoidal artery ligation. ResultsThe surgical principle of Doppler-guided hemorrhoidal artery ligation make use of Doppler ultrasound looking for hemorrhoidal artery, and ligation it directly.It's best indication is Ⅱ or Ⅲ degree hemorrhoids or mixed hemorrhoid with grade Ⅰ or Ⅲ mainly, especially for bleeding hemorrhoids disease curative effect is better.This surgical method has lots of advantages, such as less invasive, quick recovery, and low incidence of complications.But it is no significant treatment effect for the external hemorrhoids, therefore, the procedure does not apply to external hemo-rrhoids and mixed hemorrhoids dominated by external hemorrhoids. ConclusionsDoppler-guided hemorrhoidal artery ligation has the advantage of minimally invasive, it is a safe and effective treatment for Ⅱ and Ⅲ degree internal hemorr-hoids or Ⅱ and Ⅲ degree mixed hemorrhoids dominated by internal hemorrhoids.
