Comparison of Neurolytic Block Techniques for the Treatment of Abdominal Visceral Pain and Their Influence On The Quality of Life of Patients With Cancer

The neurolytic blocks of sympathetic chains are commonly used for the treatment of cancer-related pain. This study aims to compare celiac plexus neurolysis and splanchnic nerve neurolysis for the treatment of abdominal visceral pain and its influence on the quality of life of patients with cancer.

Inclusion: Patients aged 18 years or older Presence of localized visceral pain in the upper abdomen originating from cancer of the stomach, duodenum, distal esophagus, ascending or transverse colon, liver, biliary tract, or pancreas; Ineffectiveness of analgesic treatment with third-step opioids according to the WHO analgesic ladder, including:; Opioids (≥ 60 mg/day of morphine equivalents) Antidepressants (tricyclic or dual-action), at any dosage Gabapentinoids, at any dosage Presence of side effects from analgesics that are difficult to manage with medication.

Exclusion: Clinical coagulation disorder, defined as:; Presence of ascites Presence of deep vein thrombosis Presence of hepatic failure: Child-Pugh class B or C Presence of renal failure: estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m² Use of any anticoagulant medication; INR > 1.5 Prothrombin activity < 70% or prothrombin time > 13.5 seconds aPTT > 40 seconds Cardiovascular failure: NYHA class III.
