Uitkomstmaten
Primaire uitkomstmaten
The primary parameter is the difference in short-term efficacy between P-SNN and EUS-CGN. <br>
• Pain is measured using a 11-point numeric rating scale (0-10) for upper abdominal or back pain. Pain is assessed after seven days, the patient is asked about the pain score with regard to the previous 24 hours. This is compared to the patients baseline pain score in order to determine the reduction in pain (=efficacy).<br>
• Baseline pain score is based on an assessment by the patient. The average pain score from the three consecutive days prior to the procedure will be used to determine the baseline pain score.
Achtergrond van het onderzoek
Patients with intra-abdominal malignancies, especially pancreatic carcinoma, are often inoperable at the time of diagnosis. For those patients, palliative therapy is the only option. Intra-abdominal malignancies are often associated with severe chronic pain. Celiac plexus neurolysis (CPN), either as a replacement or in addition to opioid usage, is an effective treatment option. Traditionally, percutaneous CPN (P-CPN) is performed by an anesthesiologist. The anesthesiologist uses a percutaneous approach to block the celiac plexus itself or the splanchnic nerves (percutaneous splanchnic nerve neurolysis; P-SNN), from which the celiac plexus nerves originate. Reaching the celiac plexus using endoscopic ultrasound (EUS) is a good, if not better, alternative. Recently, injection of a neurolytic agent with EUS directly in the celiac ganglia (EUS-CGN) proved superior to EUS-CPN. Direct comparison between P-SNN and EUS-guided neurolysis in malignant intra-abdominal pain has not been performed. Therefore, we set out to perform such a study. Since EUS-CGN proved superior to EUS-CPN, this technique will be used. We hypothesize that EUS-CGN is more effective in achieving adequate pain reduction in malignant upper-abdominal pain or back pain than percutaneous splanchnic nerve neurolysis (P-SNN).

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
• Diagnosis of an inoperable malignant tumor in the abdomen by histopathological or imaging findings.
o Inoperable malignancy is defined as local tumor infiltration into surrounding organs, distant metastases or a poor general health due to serious concomitant disease.
• Baseline pain score of ≥3 on a 11-point numeric rating scale (0-10) for upper abdominal or back pain. This is assessed on the three consecutive days prior to the procedure and the average score is used as a baseline pain score.
• ≥18years old.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
• Previous CPN
• Patients with a poor mental condition or mental retardation, unable to understand the nature and possible consequences of the study
• Coagulopathy (INR>1.5, platelets<50.000/mm3) which has not been corrected prior to the procedure
• Pregnancy
• Previous participation in this trial
• Severe allergy to contrast
• Systemic infection or infection at the location of the first lumbar vertebra.
• Karnofsky performance scale of <30%
