Hemorrhoids are a common anorectal disorder whose symptoms can be recurrent, sometimes resolving on their own, and in addition to chronic symptoms, can sometimes be acute. Hemorrhoids are symptomatic enlargement and displacement of the anal cushion tissue. Many factors are thought to contribute to the formation of hemorrhoids, and hemorrhoid treatments are even more varied. Many factors can contribute to the development of hemorrhoids, such as: constipation, diarrhea, struggle, strenuous exercise, weight-bearing, pregnancy, increased abdominal pressure, hereditary factors, age, and more. These factors lead to increased pressure on the submucosal hemorrhoidal arteriovenous plexus, enlargement of the anal cushion, and weakness of the supporting connective tissue, which over time leads to prolapse of hemorrhoids. Hemorrhoids are a common benign disease of the anorectal region, but their epidemiology is not clear. Because of the specific location of this disease, patients prefer to medicate themselves rather than go to the hospital for examination. The prevalence of hemorrhoids has been shown in clinical epidemiologic surveys to be about 4.4-36.4%, with no gender difference, and is high in the age range of 45-65 years; whereas about 50% of people around 50 years of age sometimes experience symptoms related to hemorrhoids. But this estimate may be higher than the true number because people may attribute all anorectal symptoms to hemorrhoids. Studies have shown that people of high socioeconomic status are more likely to develop them, which may be related to dietary structure. Constipation and struggle are thought to be the main causes of hemorrhoids because dry, hard stools and increased intra-abdominal pressure can lead to impaired venous return, which results in congestion and dilation of the hemorrhoidal venous plexus. However, diarrhea has also been found to be a risk factor for hemorrhoids; pregnancy tends to aggravate hemorrhoidal symptoms by congestion of the anal cushions, but the symptoms can be relieved on their own after delivery. Other conditions that cause increased abdominal pressure, such as ascites and chronic coughing, can trigger or aggravate hemorrhoids. Age and genetic factors can also lead to the deterioration of supporting tissues such as fibrous connective tissue and smooth muscle tissue, which can lead to prolapsed hemorrhoids. In addition, dietary factors such as low-fiber foods, spicy foods, coffee, and alcohol consumption can exacerbate the symptoms of hemorrhoids. Treatment of hemorrhoids ranges from dietary and lifestyle modifications to surgical procedures, depending on the grade and severity of the hemorrhoids. The treatment of hemorrhoids is evaluated by the disappearance of symptoms: when the symptoms are mild, some minimally invasive treatments should be taken, such as sclerotherapy, rubber band ligation, Doppler ultrasound-guided hemorrhoidal artery ligation (DGHAL); if the symptoms of hemorrhoids recur repeatedly, or there is a serious prolapse or a combination of other perianal diseases, then surgical treatments should be considered, and the doctor should choose the most suitable operation style for the patient based on the pathophysiology of the disease and the indications for the operation. The doctor should choose the most suitable operation for the patient according to the pathophysiology of the disease and the indications of the operation. The choice of hemorrhoid treatment should follow the following principles, on the basis of removing hemorrhoidal symptoms, minimizing postoperative complications, such as pain, bleeding, edema, etc., and reducing the postoperative recurrence rate as much as possible, so that the patient can return to normal work and life sooner.
