Objectives To evaluate the effect of metrinidazole treatment after conventional hemorrhoidectomy pain in patients with third and fourth degree hemorrhoids. Methods We searched the Cochrane Library (Issue 1 2009), PubMed (1966 to March 2009), EMbase (1974 to March 2009), SCI (1974 to March 2009), CBM (1978 to March 2009), CNKI (1994 to March 2009), and VIP (1989 to March 2009) to identify randomized controlled trials or quasi- randomize controlled trials of metronidazole versus placebo for treating post hemorrhoidectomy pain. We evaluated the quality of the included studies by using the Handbook 4.2.6 recommend standards and analyzed data using the Cochrane Collaboration’s RevMan 4.2.10. Results We included seven randomized controlled trials or quais-randomized controlled trials (n=553). Meta-analyses showed that there were statistical differences between metronidazole and placebo in pain after hemorrhoidectomy and the use of an additional dose of analgesia. Conclusions The current evidence shows that metronidazole relieves the pain after conventional hemorrhoidectomy and reduces the additional used of analgesics. Further high quality, large sample randomized controlled trials should be carried out.
Objective To analyse the prevalence of hemorrhoids in 1 795 regular healthcheck adults in our hospital, and to investigate the etiologic features and preventive measures. MethodsThe anal examination data of 1 795 regular healthcheck adults werer reviewed and analysed mainly on the clinical features of hemorrhoids. Results All of these adults had long-sitting jobs and did less exercises. The prevalence of hemorrhoids was about 67.02% (1 203/1 795), of which mixed type was predominant (53.37%, 958/1 795) and constituent ratio was 79.63% (958/1 203)， Plt;0.05. The prevalence of hemorrhoids increased with age, especially in adults more than 60 years of age (gt;70%). The females under 30 years of age suffered from hemorrhoids more than the couterpart males 〔61.11% (44/72) vs. 22.50% （9/40)〕, Plt;0.05. There was no significant difference of hemorrhoids in gender whose age was above 30 years (P＞0.05). Conclusions Hemorrhoids, especially mixed types, are prevalent among the people who has a long-sitting and less sports lifestyle. More active preventive measures shall be taken in this group of people.
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.
