Review
Hemorrhoids is recognized as one of the most common medical conditions in general population. It is clinically characterized by painless rectal bleeding during defecation with or without prolapsing anal tissue. Generally, hemorrhoids can be divided into two types: internal hemorrhoid and external hemorrhoid. External hemorrhoid usually requires no specific treatment unless it becomes acutely thrombosed or causes patients discomfort. Meanwhile, low-graded internal hemorrhoids can be effectively treated with medication and non-operative measures (such as rubber band ligation and injection sclerotherapy). Surgery is indicated for high-graded internal hemorrhoids, or when non-operative approaches have failed, or complications have occurred. Although excisional hemorrhoidectomy remains the mainstay operation for advanced hemorrhoids and complicated hemorrhoids, several minimally invasive operations (including Ligasure hemorrhoidectomy, doppler-guided hemorrhoidal artery ligation and stapled hemorrhoidopexy) have been introduced into surgical practices in order to avoid post-hemorrhiodectomy pain. This article deals with some fundamental knowledge and current treatment of hemorrhoids in a view of a coloproctologist - which includes the management of hemorrhoids in complicated situations such as hemorrhoids in pregnancy, hemorrhoids in immunocompromised patients, hemorrhoids in patients with cirrhosis or portal hypertension, hemorrhoids in patients having antithrombotic agents, and acutely thrombosed or strangulated hemorrhoids. Future perspectives in the treatment of hemorrhoids are also discussed.

Review
Although hemorrhoids are responsible for considerable economic cost and personal suffering, they have received surprisingly little research attention. In the United States, hemorrhoids are the third most common outpatient gastrointestinal diagnosis with nearly 4 million office and emergency department visits annually. The etiology of hemorrhoids is speculative. A low-fiber diet and constipation have historically been thought to increase the risk for hemorrhoids, but not proven. Symptoms commonly attributed to hemorrhoids include bleeding, pain, pruritus, fecal seepage, prolapse, and mucus discharge. Research has found that these symptoms were equally reported by patients with and without hemorrhoids. Medical therapies for hemorrhoids have not been formally studied except for fiber where the results have been inconsistent. A number of office-based interventions such as rubber band ligation and infrared coagulation are widely used and economically favorable for practitioners. Surgical procedures are effective at eliminating hemorrhoids but may be painful. Given the burden of disease and numerous gaps in our understanding, the time has come for targeted research to understand the cause, symptoms, and best treatment for patients with symptomatic hemorrhoids.

Review
Background and Objectives: Excisional hemorrhoidectomy is considered as a mainstay operation for high-grade hemorrhoids and complicated hemorrhoids. However, postoperative pain remains a challenging problem after hemorrhoidectomy. This systematic review aims to identify pharmacological and non-pharmacological interventions for reducing post-hemorrhoidectomy pain. Materials and Methods: The databases of Ovid MEDLINE, PubMed and EMBASE were systematically searched for randomized controlled trails (published in English language with full-text from 1981 to 30 September 2021) to include comparative studies examining post-hemorrhoidectomy pain as their primary outcomes between an intervention and another intervention (or a sham or placebo). Results: Some 157 studies were included in this review with additional information from 15 meta-analyses. Fundamentally, strategies to reduce post-hemorrhoidectomy pain were categorized into four groups: anesthetic methods, surgical techniques, intraoperative adjuncts, and postoperative interventions. In brief, local anesthesia-alone or combined with intravenous sedation was the most effective anesthetic method for excisional hemorrhoidectomy. Regarding surgical techniques, closed (Ferguson) hemorrhoidectomy performed with a vascular sealing device or an ultrasonic scalpel was recommended. Lateral internal anal sphincterotomy may be performed as a surgical adjunct to reduce post-hemorrhoidectomy pain, although it increased risks of anal incontinence. Chemical sphincterotomy (botulinum toxin, topical calcium channel blockers, and topical glyceryl trinitrate) was also efficacious in reducing postoperative pain. So were other topical agents such as anesthetic cream, 10% metronidazole ointment, and 10% sucralfate ointment. Postoperative administration of oral metronidazole, flavonoids, and laxatives was associated with a significant reduction in post-hemorrhoidectomy pain. Conclusions: This systematic review comprehensively covers evidence-based strategies to reduce pain after excisional hemorrhoidectomy. Areas for future research on this topic are also addressed at the end of this article.

Many Americans between 45 and 65 years of age experience hemorrhoids. Hemorrhoidal size, thrombosis, and location (i.e., proximal or distal to the dentate line) determine the extent of pain or discomfort. The history and physical examination must assess for risk factors and clinical signs indicating more concerning disease processes. Internal hemorrhoids are traditionally graded from I to IV based on the extent of prolapse. Other factors such as degree of discomfort, bleeding, comorbidities, and patient preference should help determine the order in which treatments are pursued. Medical management (e.g., stool softeners, topical over-the-counter preparations, topical nitroglycerine), dietary modifications (e.g., increased fiber and water intake), and behavioral therapies (sitz baths) are the mainstays of initial therapy. If these are unsuccessful, office-based treatment of grades I to III internal hemorrhoids with rubber band ligation is the preferred next step because it has a lower failure rate than infrared photocoagulation. Open or closed (conventional) excisional hemorrhoidectomy leads to greater surgical success rates but also incurs more pain and a prolonged recovery than office-based procedures; therefore, hemorrhoidectomy should be reserved for recurrent or higher-grade disease. Closed hemorrhoidectomy with diathermic or ultrasonic cutting devices may decrease bleeding and pain. Stapled hemorrhoidopexy elevates grade III or IV hemorrhoids to their normal anatomic position by removing a band of proximal mucosal tissue; however, this procedure has several potential postoperative complications. Hemorrhoidal artery ligation may be useful in grade II or III hemorrhoids because patients may experience less pain and recover more quickly. Excision of thrombosed external hemorrhoids can greatly reduce pain if performed within the first two to three days of symptoms.

Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up.

Review
INTRODUCTION
Haemorrhoids are cushions of submucosal vascular tissue located in the anal canal starting just distal to the dentate line. Incidence is difficult to ascertain as many people with the condition will never consult with a medical practitioner, although one study found 10 million people in the USA complaining of the disease.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for haemorrhoidal disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2008 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 44 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: closed haemorrhoidectomy, haemorrhoidal artery ligation, infrared coagulation/photocoagulation, injection sclerotherapy, open excisional (Milligan-Morgan/diathermy) haemorrhoidectomy, radiofrequency ablation, rubber band ligation, and stapled haemorrhoidectomy.

Review
Hemorrhoids are local vascular structure dilations in the lower rectum, associated with morbidity and reduced quality of life. Endovascular coil or particle embolization of the superior rectal arteries, known as Emborrhoid technique, is a minimally invasive, image-guided therapy that targets the hemorrhoidal plexus and reduces hemorrhage. The purpose of this review was to analyze the results of published studies to determine the efficacy, clinical outcomes, and morbidities associated with the endovascular occlusion of hemorrhoidal arteries for the treatment of internal hemorrhoids. Current evidences suggest that hemorrhoids treated by Emborrhoid technique using microcoils, embolic particles or a combination is safe with no reported serious complications. Hemorrhoid embolization can preserve the anal tone without direct anorectal trauma and maintain the hemorrhoidal tissue in place requiring minimal local wound care on an outpatient basis. However, due to the paucity of high-quality trials, further research is warranted to evaluate its long-term outcomes, compare its efficacy with other treatment modalities, and fully assess its role in the treatment of hemorrhoid.

Review
This review discusses the pathophysiology, epidemiology, risk factors, classification, clinical evaluation, and current non-operative and operative treatment of hemorrhoids. Hemorrhoids are defined as the symptomatic enlargement and distal displacement of the normal anal cushions. The most common symptom of hemorrhoids is rectal bleeding associated with bowel movement. The abnormal dilatation and distortion of the vascular channel, together with destructive changes in the supporting connective tissue within the anal cushion, is a paramount finding of hemorrhoids. It appears that the dysregulation of the vascular tone and vascular hyperplasia might play an important role in hemorrhoidal development, and could be a potential target for medical treatment. In most instances, hemorrhoids are treated conservatively, using many methods such as lifestyle modification, fiber supplement, suppository-delivered anti-inflammatory drugs, and administration of venotonic drugs. Non-operative approaches include sclerotherapy and, preferably, rubber band ligation. An operation is indicated when non-operative approaches have failed or complications have occurred. Several surgical approaches for treating hemorrhoids have been introduced including hemorrhoidectomy and stapled hemorrhoidopexy, but postoperative pain is invariable. Some of the surgical treatments potentially cause appreciable morbidity such as anal stricture and incontinence. The applications and outcomes of each treatment are thoroughly discussed.

Colorectal cancer (CRC) is a common disease and one of the leading causes of cancer deaths worldwide. This retrospective cohort study evaluated the risk of developing CRC in people with hemorrhoids. Using Taiwan's National Health Insurance Research Database, we established three sets of retrospective study cohorts with and without hemorrhoids. The first set of cohorts were matched by sex and age, the second set of cohorts were matched by propensity score without including colonoscopies, and the third set of cohorts were matched by propensity score with colonoscopies, colorectal adenomas, and appendectomies included. In the second set of cohorts, 36,864 persons with hemorrhoids that were diagnosed from 2000 to 2010 and a comparison cohort, with the same size and matched by propensity score, were established and followed up to the end of 2011 to assess the incidence and Cox proportional regression-measured hazard ratio (HR) of CRC. The overall incidence rate of CRC was 2.39 times greater in the hemorrhoid cohort than it was in the comparison cohort (1.29 vs. 0.54 per 1000 person-years), with a multivariable model measured adjusted HR of 2.18 (95% CI = 1.78-2.67) after controlling for sex, age, and comorbidity. Further analysis on the CRC incidence rates among colorectal sites revealed higher incidence rates at the rectum and sigmoid than at other sites, with adjusted HRs 2.20 (95% CI = 1.48-3.28) and 1.79 (95% CI = 1.06-3.02), respectively. The overall incidence rates of both cohorts were similar in the first and second sets of cohorts, whereas the rate was lower in the third set of hemorrhoid cohorts than in the respective comparison cohorts, probably because of overmatching. Our findings suggest that patients with hemorrhoids were at an elevated risk of developing CRC. Colonoscopy may be strongly suggested for identifying CRC among those with hemorrhoids, especially if they have received a positive fecal occult blood test result.
