Active clinical trials for "Hemorrhoids"

A single blind, randomized, with blinded evaluation by third parties clinical trial is carried out to assess the analgesic efficay of the addition of morphine chloride to a low dose solution of spinal local anaesthetic compared to a standard dose spinal anaesthetic in the haemorrhoid surgery. The objective of this clinical trial is to assess if the experimental treatment is as efficacy as the standard treatment in the anesthetic and analgesic effects with less side effects, greater and earlier mobility after surgery and shortened the hospitalization.

Hemorrhoidal disease occurs in 50% of people over 40 years old and is the most common cause of anorectal surgery. One of the complications of hemorrhoidectomy is pain, which is a difficult symptom to appreciate and assess, by its frequent and large variations in sensitivity in each patient. Many studies have been done to reduce patient postoperative pain, but there is no ideal method. The application of both oral and topical metronidazole has shown to decrease pain following hemorrhoidectomy, but its use is not standardized. The investigators evaluated the effect of oral administration of metronidazole versus homologated placebo in pain control after hemorrhoidectomy

Hemorrhoids are vascular cushions in the anal canal. People are normally born with hemorrhoids, and the presence of hemorrhoids does not imply disease. However, hemorrhoids typically cause symptoms when they enlarge over time. There are two types of hemorrhoids- External Hemorrhoids and Internal Hemorrhoids. Current minimally invasive technologies for the treatment of internal hemorrhoids are associated with several drawbacks that include high rate of recurrence and a need for repetitive procedures, frequent post-procedural pain or significant discomfort, intra-operative pain and technically demanding. The purpose of this study is to determine whether the HET Bipolar System is safe and effective in the treatment of Stage I and Stage II hemorrhoids (internal hemorrhoids). The HET Bipolar System is a new alternative device for the minimally invasive treatment of Stage I and Stage II hemorrhoids that incorporate design features with the intent of resolving each of the major limitations of currently available technology.

The purpose of this study is to compare two techniques for treating hemorrhoids, the ligation and hemorrhoidopexy technique and the conventional ligation of hemorrhoidal arteries using ultrasound, in patients with non-complicated hemorrhoids.

Hemorrhoidal disease (HD) is one of the oldest and most common proctologic diseases that has been described with an estimated prevalence between 4.4% and 86%. Despite the proposal of three mechanisms that might underlie haemorrhoidal development - the varicose vein theory, the vascular hyperplasia theory and the sliding anal-lining theory, the exact pathophysiology of symptomatic hemorrhoid disease is poorly understood. HD seems to be the most common cause for rectal bleeding, or hematochezia, and the second most frequent cause for severe rectorrhagia after diverticulitis. The blood is bright red and coats the stool at the end of defection. Other symptoms include pain, mucous discharge, itching or the sensation of tissue prolapse. The most widely accepted classification is the Goligher classification: Grade I: hemorrhoids bleed but do not prolapse out of the anal canal; Grade II: hemorrhoidal cushions prolapse outside of the anal canal on straining or during bowel movements, but reduce spontaneously; Grade III: hemorrhoidal cushions prolapse outside the anal canal on straining and require manual reduction; Grade IV: hemorrhoidal prolapse is irreducible even with manipulation

Haemorrhoids are vascular cushions in the anal canal that help in the control of stool. When inflamed they become pathological and may present with protrusion and bleeding. A randomized, triple blind , controlled study will be conducted to compare the efficacy of calcium dobesilate against flavanoids in the management of early haemorrhoidal disease.

Background: Hemorrhoidal disease is extremely frequent in the adult population and, as a benign pathology, the treatment should be guided by the patient's symptoms. Treatment of hemorrhoidal disease includes a conservative approach, office-based treatments and surgery. This study is aimed to evaluate and compare the efficacy and safety of the treatment of hemorrhoidal disease with non-surgical office-based method polidocanol foam sclerotherapy (SP) and the surgical technique doppler-guided hemorrhoidal artery ligation with recto-anal repair. Methods: Prospective, unicentric study including patients with symptomatic hemorrhoidal disease grade II and III refractory to conservative therapy, submitted either to SP (n=24) or to HAL-RAR procedure (n=21), during a recruitment period of 6 months. Patients were evaluated for efficacy (Sodergren's scale of symptoms and severity of bleeding) and safety (complications and implication in personal and professional life), up to one month after treatment. In follow-up period (6 months) participants were evaluated for hemorrhoidal disease recurrence.

While some investigators found oral metronidazole to be effective in reducing pain after hemorrhoidectomy, other researchers did not find a significant analgesic effect of systemic metronidazole. On the other hand, topical application of metronidazole had more consistent favorable results as Ala et al documented a remarkable analgesic effect of topical metronidazole 10% after excisional hemorrhoidectomy which was in line with Nicholson and Armestrong who also concluded similar results. No previous study compared the analgesic effect of topical and oral metronidazole after anorectal surgery. Therefore, the present trial was conducted to compare the impact of oral versus systemic metronidazole on pain and recovery after surgery for benign anorectal conditions.

Thrombosed external haemorrhoids are one of the most frequent anorectal emergencies. They are associated with swelling and intense pain. This study evaluated the efficacy and safety of an intersphincteric injection of botulinum toxin for pain relief in patients with thrombosed external haemorrhoids

The purpose of this study is to determine which treatment, band ligation (placing rubber bands around the hemorrhoids) or BICAP electrocoagulation (using electricity to cauterize) is safer and more effective endoscopic treatment for bleeding internal hemorrhoids.
