Efficacy of the Erector Spinae Plane Block for Abdominal Pain From Gastrointestinal Malignancies

Not applicable Interventional Abramson Cancer Center at Penn Medicine · NCT07211386

This study will try an erector spinae plane nerve block to reduce severe abdominal pain and opioid use in adults with gastrointestinal cancers who come to Penn Medicine emergency departments.

What this trial studies

This project will offer an erector spinae plane block (ESPB), a regional anesthetic technique, to adults with GI malignancy who present to Penn Medicine EDs with intractable abdominal pain. Eligible patients receiving ESPB will be enrolled as a prospective cohort and compared to a matched historical control group of similar patients treated with standard ED analgesia. The primary outcome is total opioid use over 24 hours measured in milligram morphine equivalents (MMEs), with secondary outcomes including hospital length of stay and pre/post-block pain, function, and satisfaction at 24 hours. The ESPB will be performed by ED providers per institutional protocols already in use at UPHS.

Who should consider this trial

Good fit: Adults (over 18) with known gastrointestinal malignancy who present to a participating Penn Medicine ED with intractable abdominal pain and a same-day or recent CT showing a malignant source, who are medically stable and able to consent, are the intended participants.

Not a fit: Patients with non-malignant causes of pain, hemodynamic instability, allergy to ropivacaine or history of local anesthetic toxicity, pregnancy, incarceration, inability to consent, admission for serial abdominal exams, or prior enrollment are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, the ESPB could lower opioid needs and pain levels and possibly shorten hospital stays for patients with cancer-related abdominal pain.

How similar studies have performed: Regional anesthesia techniques including ESPB have shown pain and opioid-sparing benefits in perioperative and acute pain case series and small trials, but high-quality evidence specifically for ED management of GI cancer pain is limited.
