NCT ID: NCT04290351 Completed - Clinical trials for Hemorrhoids, Internal

The Effect of Rubber Band Ligation in Bleeding Internal Hemorrhoids.

Start date: November 1, 2020
Phase:
Study type: Observational

In this study, the researchers planned to compare the treatment results of patients undergoing rubber band ligation in addition to drug therapy in hemorrhagic internal hemorrhoids patients and those treated only with anti-hemorrhoidal drugs.

Polidocanol Foam Versus Rubber Band Ligation in the Treatment of Hemorrhoidal Disease

Start date: August 1, 2018
Phase: Phase 2
Study type: Interventional

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.

Safety and Efficacy Study of HET Bipolar System for Treatment of Stage I and Stage II Hemorrhoids

Start date: April 2013
Phase: N/A
Study type: Interventional

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.
