Spinal Cord Stimulation
Donnée non disponible
A stimulation electrode is placed in the epidural space between the T4-T7 spinal levels and connected to an external electrical pulse generator, which is used for stimulation. The stimulus intensity is initially increased in a ramp-like fashion using high-frequency stimulation at 1000 Hz, with pulse widths of 90 microseconds and intensities increasing from 2 to 14 mA to establish the sensation threshold. After establishing the sensation threshold, the 75 % subthreshold of sensation is used as the stimulation intensity during the active stimulation period.
Inconnu
Sham
Donnée non disponible
For sham treatment, a similar procedure for establishing the sensation threshold is used, and stimulation at the 75 % subthreshold intensity is initiated, but the stimulation device is turned off 30 seconds after the sensation subthreshold is established.

Résumé de l'étude
Chronic pancreatitis leads to severe abdominal pain in up to 70% of patients, and several studies have proposed it has a neuropathic component. Current treatments often fail to provide adequate pain relief, necessitating new innovations for management. Spinal cord stimulation has been proposed to treat severe neuropathic pain refractory to conventional treatment, but sham-controlled trials have not previously been done in patients with visceral pain. This study will test the effect of spinal cord stimulation in chronic pancreatitis patients with insufficient pain relief from standard therapies.

Chronic pancreatitis (CP) is a condition causing considerable morbidity, with nearly 0.5 million new cases emerging in Europe every year. It is characterized by a fibro-inflammatory process that progressively damages the pancreas. As the disease advances, most patients experience exocrine pancreatic insufficiency and diabetes, but the most debilitating aspect is severe abdominal pain, which affects about 70% of patients. The pain's origins in CP are complex, typically associated with pancreatic inflammation, ductal obstruction, damage to pancreatic nerves due to inflammation and fibrosis, and resulting neuropathy that triggers sensitization in the pain pathways. This may lead to self-perpetuating pain independent of its initial cause.
Current CP pain management involves conventional analgesics, neuromodulators, and specific endoscopic or surgical interventions for selected cases. However, a substantial number of patients still struggle with inadequate pain relief despite these treatments, necessitating innovative approaches to address CP-associated pain effectively.
Spinal cord stimulation (SCS) is a reversible invasive technique that involves stimulating spinal cord neurons and axons using low-voltage electrical current through leads placed in the epidural space behind the spinal cord dorsal columns. The mechanisms through which neurostimulation may alleviate pain and induce neuroplasticity are intricate and impact multiple neuronal and pain pathways. SCS has shown efficacy in managing neuropathic pain. However, there is a lack of sham-controlled research investigating SCS's effect on visceral pain conditions, including CP.
Hypothesizing that SCS, when compared to sham stimulation, can offer clinically significant pain relief and enhance physical functioning and quality of life in CP patients, an investigator-led, randomized, double-blinded, sham-controlled, cross-over study is initiated.
