Study summary

This phase II trial compares the effect of rectus sheath block with liposomal bupivacaine to thoracic epidural analgesia (TEA) on pain control in patients following surgical removal of all or part of the pancreas and duodenectomy (pancreatoduodenectomy). Administering long acting local anesthetics, such as liposomal bupivacaine, in between the muscle layers of the abdomen (rectus sheath block) may help with pain relief during and after surgery. TEA uses a needle to insert a flexible plastic catheter into the thoracic spine to administer anesthetic and pain medication, such as bupivacaine and hydromorphone, to treat pain in the thoracic and upper abdominal areas during and after surgery. Epidurals have been successfully used to treat pain after surgery, however, it does have a risk of low blood pressure which may limit the use in the thoracic approach. Rectus sheath blocks with liposomal bupivacaine may be as effective as TEA in reducing pain in patients following a pancreatoduodenectomy.

Read the detailed description

PRIMARY OBJECTIVE:

I. To determine if rectus sheath blocks with liposomal bupivacaine provide non-inferior analgesia compared with thoracic epidural analgesia (TEA) for patients undergoing pancreatoduodenectomy.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP EPIDURAL (E): Prior to pancreatoduodenectomy, patients undergo thoracic epidural placement and receive bupivacaine and hydromorphone continuous infusion via epidural for up to 72 hours postoperatively. Patients also receive iopamidol via epidural and undergo x-ray imaging on study.

GROUP RECTUS SHEATH (RS): Prior to pancreatoduodenectomy, patients undergo ultrasound and receive bupivacaine and liposomal bupivacaine injection into the rectus sheath.

Inclusion criteria

  • Adult patients, age 18 and older, undergoing open pancreaticoduodenectomy at the University of Minnesota will be included in the study

Exclusion criteria

Exclusion Criteria:

  • Patients with to block placement (coagulopathy, local anesthetic allergy, infection)
  • Patients with chronic opioid use (at least 30 milligram morphine equivalents [MME] for 3 or more weeks leading up to surgery)
  • Patients unable to understand the quality of recovery survey intellectual barriers. This will be determined by the primary investigator/attending anesthesiologist's discretion
  • Patient refusal and those who have opted out of research
  • Pregnant patients - will be assessed through review of the medical record

What researchers measure

Primary outcomes

  1. Milligram morphine equivalents (MME)

    Opioid consumption will be evaluated as a non-inferiority hypothesis using a two-sample t-test to compare the groups, with the conclusion of statistical significance being drawn from the corresponding confidence interval for the differences in mean MMEs between groups.

    Time frame: Up to 96 hours after open pancreatoduodenectomy

Secondary outcomes

  1. Pain scores

    Pain scores at rest and with movement will be assessed using a numeric rating scale pain scores where 0 is no pain and 10 is worst pain.

    Time frame: At 24, 48, 72 and 96 hours

  2. Hospital length of stay

    Average hospital length of stay

    Time frame: Up to 7 days after surgery

  3. Opioid consumption

    Average Opioid consumption (milligrams)

    Time frame: 96 hours

  4. Time to return of bowel function

    Average time to return of bowel function will be measured by first oral intake.

    Time frame: Up to 7 days after surgery

  5. Incidence of nausea, vomiting, hypotension and pruritis

    Time frame: At 24 hours, 48 hours, 72 hours and 96 hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 3, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
