Coeliac Plexus vs Splanchnic Nerve Neurolysis for Upper Abdominal Cancer Pain

2 september 2026 uppdaterad av: Kazi Mahzabin Arin, Bangladesh Medical University

Effect of Coeliac Plexus Versus Splanchnic Nerve Neurolysis in Pain Management With Upper Abdominal Malignancies

The goal of this clinical trial is to determine whether Neurolytic Splanchnic Nerve Block (NSNB) reduces pain in adults with upper abdominal malignancies. It will also evaluate the safety of Neurolytic Splanchnic Nerve Block (NSNB). The main questions it aims to answer are:

Does NSNB reduce pain intensity compared to Neurolytic Coeliac Plexus Block (NCPB), as measured by the Visual Analog Scale (VAS)? What adverse effects do participants experience when receiving Neurolytic Splanchnic Nerve Block (NSNB)?

Investigators will compare Neurolytic Splanchnic Nerve Block (NSNB) with Neurolytic Coeliac Plexus Block (NCPB) to determine which intervention provides more effective and safer pain relief.

Participants will:

  • receive either NSNB or NCPB under fluoroscopic guidance
  • be monitored immediately and for 2 hours after the procedure for any complications Have their pain intensity recorded immediately after the procedure, and at 7 days, 1 month, and 3 months
  • be evaluated for quality-of-life using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 3 (EORTC QLQ-C30) at 1 month and 3 months.
  • have their opioid consumption tracked throughout the study.

Studieöversikt

Detaljerad beskrivning

This study is a quasi-experimental, interventional trial conducted at the Division of Pain Medicine & Regional Anaesthesia, Department of Anaesthesia, Analgesia and Intensive Care Medicine, Bangladesh Medical University, Dhaka. Adult patients diagnosed with upper abdominal malignancies (including pancreatic, gastric, hepatic, or biliary origin) who report moderate to severe pain (VAS ≥5) and have no contraindications for nerve blocks will be enrolled.

Eligible participants will be allocated in a 1:1 ratio into two groups. The control group will receive a fluoroscopy-guided Neurolytic Coeliac Plexus Block (NCPB). The procedure involves patient positioning in the prone posture with abdominal flexion, identification of anatomical landmark L1 under posteroanterior and oblique C-arm fluoroscopy, skin infiltration with local anesthetic, and injection of 3 mL 0.25% bupivacaine, followed by 20 mL of 70% alcohol for neurolysis, with 1 mL saline flush during needle withdrawal to prevent tract formation. The study group will receive a fluoroscopy-guided Neurolytic Splanchnic Nerve Block (NSNB) using a similar approach, with needle placement at the T11-T12 level, 3 mL of local anesthetic, and 10 mL of 70% alcohol for neurolysis.

Baseline evaluations will include a complete blood count, a coagulation profile (prothrombin time, bleeding time, clotting time, INR), a Visual Analog Scale (VAS) pain score, and a quality-of-life assessment using the EORTC QLQ-C30. Participants will be monitored immediately and for 2 hours post-procedure for complications, including hypotension, diarrhea, back or shoulder pain, pneumothorax, or neurological changes.

Follow-up assessments will occur immediately post-procedure, at 7 days, 1 month, and 3 months. Pain intensity, opioid consumption, and quality-of-life scores will be recorded.

This study aims to provide comparative data on analgesic efficacy, opioid-sparing effects, safety, and quality-of-life outcomes between NCPB and NSNB in patients with upper abdominal malignancies.

Intervention / Behandling
Experimentell: Interventionsgrupp
Fluoroscopy-guided neurolytic splanchnic nerve block performed in adults with upper abdominal malignancies. Patients are positioned prone with proper support. Using posteroanterior and lateral C-arm fluoroscopy, T11-T12 vertebral bodies and the junction of the rib and vertebral body are identified. After local anesthetic infiltration, a Chiba needle is advanced to the anterior one-third of the lateral vertebral body. Contrast dye is injected to confirm placement. Neurolysis is performed using 10 mL of 70% alcohol, preceded by 2-3 mL of 0.25% bupivacaine. A 1 mL saline flush is given during needle withdrawal to prevent track formation. Patients are monitored immediately and for 2 hours post-procedure for complications including hypotension, diarrhea, back pain, shoulder pain, pneumothorax, or neurological changes.
Aktiv komparator: Kontrollgrupp
Fluoroscopy-guided neurolytic coeliac plexus block performed on adult patients with upper abdominal malignancies. Patients are positioned prone with a pillow under the abdomen. Using posteroanterior and oblique C-arm fluoroscopy, the T12-L1 vertebral bodies are identified. After local anesthetic infiltration, 3 mL of 0.25% bupivacaine is injected, followed by 20 mL of 70% alcohol for neurolysis. A 1 mL saline flush is given during needle withdrawal to prevent track formation. Patients are monitored immediately and for 2 hours post-procedure for adverse effects including hypotension, diarrhea, back pain, shoulder pain, or neurological changes.
