Multicenter Prospective Trial on Hemorrhoids


Brief description of study

This study will compare Ferguson hemorrhoidectomy and THD in terms of one-year recurrence in a large population (N=492). Recurrence is defined as prolapsing internal hemorrhoids at physical examination performed by a colorectal surgeon.

Detailed Study Description

This is a multicenter, parallel arm, non-randomized prospective data collection trial comparing Ferguson hemorrhoidectomy and THD in terms of recurrence rates at one-year. All subjects will already be scheduled for either Ferguson or THD hemorrhoidectomy, the surgery is NOT part of the research. Although a randomized study would control for variation among surgeons, this study design provides the best patient safety since the surgeons will perform the technique they do most frequently. Variability in the patient population will be managed with a conservative sample size, which allows for a multivariate analysis of the sample populations if any confounding variables are noted during initial data analyses. In addition, the variability will be minimized with stringent and detailed inclusion/exclusion criteria in terms of hemorrhoidal disease. Patients will be enrolled and followed for one year. Participating surgeons will be credentialed and each participating surgeon will enroll up to ten consecutive patients.

The primary endpoint of this study is to compare Ferguson hemorrhoidectomy and THD in terms of recurrence rates at one-year. Recurrence is defined as prolapsing internal hemorrhoids at physical examination performed by a colorectal surgeon.
