Active clinical trials for "Hemorrhoids"

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.

Symptomatic haemorrhoids, or piles, have significant effects on quality of life. The treatment for advanced disease is surgical excision (haemorrhoidectomy) which is extremely effective. However, pain following haemorrhoidectomy is known by all to be a miserable experience and current treatment is not very effective. We have formulated a new cream treatment which targets three theorised mechanisms of pain after haemorrhoidectomy. We will test the effectiveness of the treatments with a multi-centred randomised controlled factorial trial with four parallel double-blinded arms containing different combinations of the active agents. The outcomes include pain scores, amount of analgesia required and time to return to work. The results of our study could provide evidence of an effective treatment for post haemorrhoidectomy pain. The treatment may provide considerable benefit to patients undergoing this surgical procedure.

Trial Objectives The primary objectives of this clinical trial are to estimate the Covidien EEA™ Hemorrhoid and Prolapse Stapling Set: overall performance defined by the successful creation of a normal staple line safety as measured by the 30 day incidence of adverse events.

Purpose: The current study aims to evaluate the safety and effectiveness of the HET™ Bipolar System (Medtronic, Boulder, CO) for the treatment of grade I-II hemorrhoids in a prospective pilot study. This device was evaluated retrospectively in a limited cohort of 23 patients previously. Methods: Patients seen at a colorectal clinic in a single institution with grade I-II hemorrhoids are offered to participate in a prospective pilot trial. The HET device is a modified anoscope equipped with LED lighting, a tissue clamping mechanism and a bipolar energy source used to treat multiple hemorrhoidal columns in one sitting. Three columns of hemorrhoids are treated with 2 heat energy applications per column. The primary outcome is the treatment effect on hemorrhoid symptoms of bleeding, pain, prolapse, itching, and soiling. This is measured with a patient completed questionnaire documenting each symptom's frequency from 0 to 3 (i.e. 0 is < 1x/month; 3 is daily) before therapy and at 3 weeks and 6 month follow-up. Post-treatment pain scores were recorded using the visual analog scale (VAS).

The purpose of this study is to determine the safety and effectiveness of human dehydrated amnion chorion allograft in closed hemorrhoidectomy as assessed by patient and wound assessments.

The objectives of this study are to assess the potential contribution of lidocaine hydrochloride or hydrocortisone acetate, alone or in combination, in topical cream preparations in the treatment of Grade I or II hemorrhoids and to demonstrate the safety and efficacy of the test articles when applied twice daily for 14 days in subjects with Grade I or II hemorrhoids. These products reflect common drug combinations of lidocaine hydrochloride or hydrocortisone acetate found in many prescription hemorrhoid products.

This study is being conducted to evaluate an investigational instrument called the HEM-AVERT Perianal Stabilizer and its efficacy in reducing the occurrence or severity of hemorrhoids and thrombosed external hemorrhoids (TEH) which commonly occur during vaginal delivery.

The purpose of this study is to determine whether the use of perioperative intravenous S (+) ketamine reduces the amount and degree of postoperative pain. Furthermore the purpose of this study is to determine whether the use of perioperative intravenous S (+) ketamine effects cognitive function in the early postoperative period.

Evaluation of the effect and safety of NeoFitoroid® in reducing symptoms in patients with hemorrhoidal disease.

Background: Hemorrhoidal disease is a common benign condition seen frequently in clinical settings. Rubber band ligation and sclerotherapy have proven to be the office-based procedures of choice in hemorrhoidal disease, with various studies reporting rubber band ligation as being more effective but also more painful and bleeding prone than sclerotherapy with liquid polidocanol. However, there are no studies comparing rubber band ligation and sclerotherapy with polidocanol foam, a new type of sclerosant agent that has already proved to be more effective and safer than liquid polidocanol in grade I hemorrhoidal disease. The present study was designed to establish the clinical effectiveness and safety of sclerotherapy with polidocanol foam compared with rubber band ligation. Methods: This randomized controlled trial includes patients with symptomatic hemorrhoidal disease grades I to III. The participants were randomly assigned (in a 1:1 ratio) to either rubber band ligation or sclerotherapy with polidocanol foam, stratified by grade of hemorrhoidal disease. During the intervention period the patients are submitted to one of the office-based procedures and, afterwards, in the follow-up period, evaluated every three months for a total period of one year. The efficacy outcomes include symptom resolution, number of treatment sessions needed to achieve therapeutic success and evolution of hemorrhoidal disease grade in the intervention period and, during follow-up, recurrence incidence. Primary safety outcomes include the occurrence of any complication related to the office-based procedures.
