ABSTRACT
Purpose@#Hemorrhoids are the most common benign anorectal diseases. Mucopexy strengthens the anal canal mucosa, which can be performed alone or in combination with Doppler-guided hemorrhoidal artery ligation (DG-HAL). In this study, we compared the postoperative complications between simple mucopexy plus HAL with and without a Doppler guide. @*Methods@#This study was performed as a single-blinded randomized clinical trial. Patients referred to a tertiary colorectal referral clinic with grades 3 and 4 hemorrhoids who were candidates for surgical intervention entered the study. Thirty-six patients were randomly divided into 2 groups. Group A including 18 patients underwent mucopexy and DG-HAL and the other 18 patients (group B) underwent standard mucopexy and HAL without a Doppler guide. Postoperative pain score and the duration of oral analgesic consumption were recorded. Additionally, postoperative symptoms and complications were recorded and compared between the 2 methods. @*Results@#There was no significant difference between the 2 groups in terms of pain score and the duration of postoperative analgesic consumption as well as the incidence of postoperative complications. Besides, the primary grade of hemorrhoids was not significantly associated with recurrence, but there was a significant association between body mass index and Wexner score (WS) with recurrence. The mean WS of patients showed a significant decrease in both groups postoperatively. However, the rate of WS reduction was not remarkably different between the 2 groups. @*Conclusion@#Simple mucopexy with blind HAL (without Doppler guide) might be considered for the treatment of grades 3 and 4 hemorrhoids effectively.
ABSTRACT
Anemia, particularly Iron Deficiency Anemia [IDA], is the most common hematological disorder during pregnancy with considerable complications in both mothers and fetuses. The estimation of anemia prevalence is an important step for health policy makers. Despite being considered a hot topic in epidemiological studies in Iran for the last twenty years, lack of a comprehensive overview on the findings encouraged the authors to carry out this study. All published papers in main national and international databases were systematically searched for some specific keywords to find the related studies between the years 1993 and 2007. All published studies which had reported the prevalence of anemia were included in the study except studies on refugees, patients undergoing hemodialysis, patients with thalassemia or cancer or other selective sub-populations. Two trained reviewers independently assessed the inclusion/exclusion criteria and the quality of the selected papers, summarized them and eventually analyzed the data. Ten eligible papers including 11,037 participants were entered into the analysis. The maximum and minimum reported prevalence rates of anemia during pregnancy were 4.3% and 21.5%, respectively. The overall estimate of anemia prevalence in Iranian pregnant women was 13.6 [95% CI: 8.3 - 18.9]. Excluding the only out-layer from the meta-analysis, the overall estimated prevalence was 12.4% [95%CI: 9.6%- 17.9%]. The prevalence of anemia in Iranian women during pregnancy is considerably lower than that of most EMRO countries or the one reported by WHO for Iran [> 40%] which had been performed on a small group 16 years ago. The lower prevalence rate of anemia in pregnant women versus the regional rates could be due to the improvements of the national health system and prenatal programs in recent years
