Multicenter Prospective Trial on Hemorrhoids
An observational study of Hemorrhoids, run by Stony Brook University at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: Multi-center, Non-randomized Prospective Observation Study Comparing Ferguson Hemorrhoidectomy and Transanal Hemorrhoidal Dearterialization (THD) for Prolapsed, Nonincarcerated, Reducible Hemorrhoids in Terms of 1-year Recurrence
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.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Transanal hemorrhoid dearterializationDevice
Also called THD
The hemorrhoids are operated in their natural position and not distorted by eversion The proctoscope is fully introduced transanally to reach the lower rectum. Under Doppler guidance, six arterial signals are found circumferentially above the dentate line. The approach to make the 'dearterialization' involves the transfixation of the rectal mucosa and submucosa to entrap the artery using a suture. Mucopexy is performed after the artery ligation with the same suture used for the dearterialization. Finally, the suture is tied to fix the mucopexy.
Ferguson hemorrhoidectomyProcedure or surgery
The hemorrhoids are operated in their natural position and not distorted by eversion. A Ferguson-Hill retractor is used to expose the hemorrhoids. Dissection with scissors is directed up to the dentate line where the fibers of the sphincter muscles are exposed and only a mucosal pedicle remains attached. A Buie-Smith crushing clamp is applied to this pedicle and the hemorrhoidal mass is excised at the superior level of the clamp. The pedicle is then ligated and the crushing clamp is removed. After dissection of the intermuscular septum is complete, the margins of the wound are drawn upward into the anal canal with stitches and are secured to the pedicle by the same suture. The remainder of the wound is closed with a stitch tied at the outer extremity of the wound using the same suture.

The record says: status not confirmed, as of the sponsor's last update on 10 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Suresh Yelika, MD (631-638-2215, suresh.yelika@stonybrookmedicine.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
1-year recurrence rates (time frame: 1-year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03245086, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2017; AzTrials last refreshed its copy on 27 Oct 2026.
