Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 99 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Patients scheduled for hemorrhoidectomies at NMCP

Who cannot join

  • Any patient with co-existing active purulent infection (i.e. abscess).
  • Any patient who has had previous surgical intervention for his/her hemorrhoidal disease. Previous simple incision to treat a thrombosed hemorrhoid is not considered a surgical intervention for the purposes of this study. The minimal scar produced by a small incision would not alter post-operative pain following removal of a hemorrhoidal column.
  • Any patient allergic to local anesthetics or oral pain medications
  • Any patient with a history of chronic pain
  • Any patient allergic to or has had an adverse reaction (i.e. history of gastrointestinal bleed) to a non-steroidal anti-inflammatory drugs (NSAIDs)
  • Any patient pregnant patient

About this study

Official title: Continuous Infusion of Local Anesthetic for Optimal Post Operative Pain Control Following Hemorrhoidectomy: A Randomized Double-blind Controlled Trial

Over the past decade, continuous wound infiltration systems have been introduced to treat a variety of post-surgical pain. These systems, commonly referred to pain pumps by patients, possess a catheter(s) attached to a reservoir of local anesthetic that directly infuses into the surgical site to provide local pain control thus avoiding the common and less desirable systemic effects of oral narcotic pain medication. Due to its portability, another benefit associated with these wound infiltration systems is its use as an outpatient pain control modality. Despite the apparent benefits, the verdict on the system's effectiveness in treating pain - throughout a variety of surgical fields - varies between very effective in reducing post-operative pain and reducing overall narcotic consumption for several days to completely ineffective with no reported changes in perceived pain or overall narcotic use.

Through a randomized trial comparing plain saline to a common local anesthetic, The investigators hope to evaluate the effectiveness of these pain pumps as an outpatient modality for pain management following hemorrhoidectomy patients. The investigators hypothesize that there will be a significant benefit in pain relief with the use of these pumps.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • placement of a continuous infusion pumpDevice

    Each infusion pump is placed below the mucosa of the rectum. Infusion of either the drug or saline will continue for approximately 3-4 days.

  • continuous infusion pump of bupivacaineDevice

    bupivacaine 0.25% at 4ml/hr for 3 to 4 days

Questions about this trial

What is this clinical trial studying?

A study testing placement of a continuous infusion pump and continuous infusion pump of bupivacaine in people with Hemorrhoids, run by United States Naval Medical Center, Portsmouth at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 20 Jul 2025. 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. Some participants in this study may receive a placebo. 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?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

VAS pain scales (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Jul 2025.
