A questionnaire was sent to members of the American Society of Colon and Rectal Surgeons. Four hundred and forty-five (43.6%) were tabulated to establish criteria and results of surgical treatment of hemorrhoidal disease. The most frequent indication for surgery, was internal and external hemorrhoids with mucosal prolapse. Significant differences were found in time required for complete healing, frequency of wound dehiscence, frequency of postoperative stenosis, and frequency of postoperative infection. Results did not support opinions that the closed technique was associated with significantly less pain, fewer complications, shorter hospital stay or earlier resumption of work.

Hemorrhoid treatment in Japan consists mainly of conservative therapy and conventional surgery. Cryosurgical hemorrhoidectomy, though still not widely used, has attained a reputation for low profile surgery and relatively painless recovery compared to conventional surgery, in spite of some inevitable problems. Our series includes external hemorrhoids and prolapse, which have been ruled out from the indications for cryosurgery, yet obtained satisfactory results. A threatening drawback is lower digestive tract hemorrhage, which occurred in 19 of 372 prolapse patients (5.1%) after cryosurgery. As for its pathogenesis, an autoimmune reaction at the site of the terminal ileum is postulated. Characteristics of the hemorrhage are: onset around the 14th postoperative day at night or early in the morning, and seen particularly in nervous patients. Prophylactic administration orally of covering materials may reduce incidence. Cryosurgery is certainly an effective measure for the treatment of hemorrhoids, including prolapse.

Anorectal disorders are commonly encountered in the practice of emergency medicine. Most can be diagnosed and treated in the emergency department setting. Almost all anorectal disorders once diagnosed and treated in the emergency department need appropriate follow-up to ensure adequacy of treatment, for further possible diagnostic procedures (e.g., endoscopy, biopsy), or for definitive treatment. Hemorrhoids are the most prevalent anorectal disorder and are the most common cause of hematochezia. Treatment is dependent on the degree of hemorrhoid prolapse and symptoms. Most cases can be treated by conservative medical treatment (e.g., dietary changes, sitz baths) or nonsurgical procedures (e.g., rubber band liagation, infrared coagulation). Surgical excision of symptomatic thrombosed external hemorrhoids is indicated if within 48 to 72 hours of pain onset. Anal fissures are one of the most common causes of anorectal pain. They are most frequently idiopathic, and most are located in the posterior midline of the anal canal. Most anal fissures are adequately treated by a medical approach using sitz baths, stool softeners, and analgesics. If the anal fissure becomes chronic and is not responsive to medical therapy, a lateral sphincterotomy of the internal anal sphincter is the surgical procedure of choice. Pharmacologic treatment (botulinum toxin or nitroglycerin ointment) to decrease internal anal sphincter tone has shown promise in the treatment of anal fissure. Anorectal abscesses are categorized into four types: perianal, ischiorectal, intersphincteric, and supralevator. Most are idiopathic and contain mixed aerobic-anaerobic pathogens. Fistula formation varies from 25% to 50% and is much more common with gut-derived organisms (e.g., E. coli, B. fragilis). Definitive treatment for an anorectal abscess is timely surgical incision and drainage to prevent more serious complications (e.g., serious infection, extension of the abscess). Anal carcinomas are infrequent, the majority of them being squamous cell or epidermoid carcinomas. The emergency physician must maintain a high index of suspicion and obtain a biopsy of suspicious lesions in order not to miss the diagnosis of a cancer. The most common presenting complaint of anal tumors is rectal bleeding. Combination chemotherapy and radiotherapy have shown promising results in the treatment of anal canal tumors. Bacterial, viral, and protozoal infections can be transmitted to the anorectum via anoreceptive intercourse. Such infections must be considered when a patient presents with rectal pain or discharge, tenesmus, or rectal or perineal ulcers. Proctosigmoidoscopy and rectal cultures may be necessary to determine the cause. Potential rectal complications of HIV infection include infectious diarrhea, acyclovir-resistant strains of HSV2, Kaposi's sarcoma, lymphoma, and squamous cell carcinoma. Rectal injuries may result from penetrating or blunt trauma, iatrogenic injuries, or foreign bodies. Rectal injury should be suspected when a patient presents with low abdominal, pelvic, or perineal pain or blood per rectum after sustaining trauma or undergoing an endoscopic or surgical procedure. Tetanus prophylaxis, intravenous antibiotics, and surgical intervention are indicated in all but superficial rectal tears.

Stapled Hemorrhoidectomy is when correctly indicated an easy feasible operative procedure for prolapsing internal hemorrhoids with or without a mucosal prolapse offering benefits to the patient. From July 1998 to October 2000 we treated 152 patients with a mean age of 52 (24-91) years for hemorrhoids within this study. We compared 72 patients, treated with stapled hemorrhoidectomy according to Koblandin-Longo with 80 patients who underwent a "conventional" reconstructive operation (Parks or Fansler-Arnold). All resected material was histopathologically examined. With stapler hemorrhoidectomy we found on average shorter operation times (22 vs. 53 min, p < 0.01), shorter hospitalisation (3 vs. 6.1 d, p < 0.01), significantly less postoperative pain (VAS 0-10: 1.83 vs. 3.70, p < 0.01) and fewer cumulative requests for analgesia by the patients (0.92 vs. 3.11 single doses, p < 0.01). The complication rate was 4 % in the stapler group and 11 % in the conventional group. Stapled hemorrhoidectomy was carried out only in patients with 3 degrees hemorrhoids with or without mucosal prolapse. The conventional group consisted of patients with 3 degrees prolapsing or 4 degrees fixated external hemorrhoids. Although very promising results are actually described with stapler hemorrhoidectomy, the established conventional reconstructive operations should be continued until long-term results are published.

Hemorrhoids are normal vascular structures underlying the distal rectal mucosa and anoderm. Symptomatic hemorrhoidal tissues located above the dentate line are referred to as internal hemorrhoids and produce bleeding and prolapse. Thrombosis in external hemorrhoids results in painful swelling. Symptomatic internal hemorrhoids that fail bowel management programs may be amenable to in-office treatment with rubber band ligation or infrared coagulation. Internal hemorrhoids that fail to respond to these measures or complex internal and external hemorrhoidal disease may require a surgical hemorrhoidectomy, either open or closed. A stapled hemorrhoidopexy treats symptomatic internal hemorrhoids and should be employed with care and only after thorough training of the surgeon because of the risk of rare, severe complications. The choice of procedure should be based on the patient's symptoms, the extent of the hemorrhoidal disease, and the experience of the surgeon.

Most patients with hemorrhoids experience only mild symptoms that can be treated with nonprescription topical preparations. Patients usually seek treatment when symptoms increase. Internal hemorrhoids typically present with prolapse or painless rectal bleeding. External hemorrhoids also bleed and can cause acute pain if thrombosed. Medical therapy should be initiated with stool softeners plus local therapy to relieve swelling and symptoms. If medical therapy is inadequate, surgical intervention is warranted. Rubber band ligation is the treatment of choice for grades 1 and 2 hemorrhoids. Rubber band ligation, excisional hemorrhoidectomy, or stapled hemorrhoidopexy can be performed in patients with grade 3 hemorrhoids. Rubber band ligation causes less postoperative pain and fewer complications than excisional hemorrhoidectomy and stapled hemorrhoidopexy, but has a higher recurrence rate. Excisional hemorrhoidectomy or stapled hemorrhoidopexy is recommended for treatment of grade 4 hemorrhoids. Stapled hemorrhoidopexy has a faster postoperative recovery, but a higher recurrence rate. Postoperative pain from excisional hemorrhoidectomy can be treated with nonsteroidal anti-inflammatory drugs, narcotics, fiber supplements, and topical antispasmodics. Thrombosed external hemorrhoids can be treated conservatively or excised.

Hemorrhoidal disease is the first cause of proctological consultation although epidemiology is poorly documented. Pathophysiology is complex and involves a fragmentation of supporting tissues as well as vascular changes with hypervascularization and/or impaired venous return. The only complication of external hemorrhoids is thrombosis, which is responsible for acute anal pain irrespective of bowel movements. Internal hemorrhoids most frequently cause prolapse and/or bleeding which is easily recognizable. Physical examination always confirms the diagnosis and a colonoscopy is required after 40 or 45 in order to rule out colorectal cancer.

Submucosal hemorrhoidectomy (Parks' procedure) is a recognized method for treating acute hemorrhoidal crisis. Anoderm preservation has been stressed in various techniques described for elective or emergency excisional hemorrhoidal management. Mucopexy techniques have been proven useful as an adjunct to minimally resectional techniques. A modified submucosal technique with anoderm preservation and mucopexy was applied to 45 patients who presented on an emergency basis with hemorrhoidal crisis. External piles were minimally removed, the minimum possible amount of diseased mucosa was excised, a linear incision was used at the anoderm to enter the subanodermal/mucosal plane to achieve the submucosal excision, and a mucopexy was added at the approximation of the mucosal flaps. Postoperative morbidity was minimal and pain after the procedure remained at acceptable levels. This technique allows for an excision limited to the pathology with important anatomic tissue preservation. This results in conservation of the sensitive and useful anoderm, a decreased risk of stenosis, and addresses the mucosal prolapse. The level of postoperative pain with this technique is acceptable and long-term follow-up reveals a high degree of patient satisfaction.

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.

The pathogenesis of hemorrhoids is a weakening of the anal cushion and spasm of the internal sphincter. Bowel habits and lifestyles can be risk factors for hemorrhoids. The prevalence of hemorrhoids can encompass 4 to 55% of the population. Symptoms include bleeding, pain, prolapsing, swelling, itching, and mucus soiling. The diagnosis of hemorrhoids requires taking a thorough history and conducting an anorectal examination. Goligher's classification, which indicates the degree of prolapsing with internal hemorrhoids, is useful for choosing treatment. Drug therapy for hemorrhoids is typically utilized for bleeding, pain, and swelling. Ligation and excision (LE) is considered for Grade III and IV internal and external hemorrhoids. Rubber band ligation is used to treat up to Grade III internal hemorrhoids. Phenol almond oil is effective for internal hemorrhoids up to Grade III, while aluminum potassium sulfate and tannic acid have shown efficacy in treating prolapsing in internal hemorrhoids at Grades II, III, and IV. Procedure for prolapse and hemorrhoids (PPH) is surgically effective for Grade III internal hemorrhoids; however, the long-term prognosis is not favorable, with high recurrence rates. Separating ligation is effective surgical treatment for internal/external hemorrhoids Grade III and Grade IV. The basic approach to thrombosed external hemorrhoids and incarcerated hemorrhoids is conservative treatment; however, in some acute or severe cases, surgical resection is considered. Comparing the different instruments used for hemorrhoid surgery, all reduce operating time, blood loss, post-operative pain, and length of time until the return to normal activity. They do, of course, increase the cost of the procedure.
