Percutaneous Lesioning Splanchnic Nerves in Patients With Chronic Pancreatitis

2014-08-27 03:18:16 | BioPortfolio

Summary

Chronic pancreatitis is a progressive inflammatory disease resulting in slow destruction of the pancreas. This chronic inflammation can lead to chronic abdominal pain which can last for many years. Unfortunately, medical management often is of only limited benefit in treating the pain of chronic pancreatitis.

Management of patients with intractable pain is difficult, often resulting in narcotic addiction.

Early results in a small group of patients suggest that percutaneous radiofrequent lesioning of splanchnic nerves has good potential for pain control in a subset of patients with chronic pancreatitis. Given the simplicity of the procedure, it clearly warrants reappraisal to identify its current role in pancreatic pain management.

Description

Rationale: Pain control is the most pressing problem in patients with chronic pancreatitis. Many methods have been advocated to control this pain. Unfortunately, these methods fail to control the pain in 20-50% of patients. Management of patients with intractable pain is difficult, often resulting in narcotic addiction. Percutaneous alcoholic block of the celiac plexus is, because of the risks of paralysis and catastrophic haemorrhage resulting from injury to major abdominal vasculature, restricted to patients with intractable, severe pain due to terminal pancreatic cancer. Splanchnic nerve lesioning is a useful alternative to celiac plexus block in the management of patients with chronic upper abdominal pain. The predictable relationship of the splanchnic nerves to other structures allows for accurate needle placement and hence a low risk of damage. Radiofrequent lesioning uses a high frequency alternating current to heat tissues leading to thermal coagulation. It produces predictable and accurate lesions.

Objective: To evaluate the feasibility and efficacy of percutaneous radiofrequent lesioning of splanchic nerves (PRFLSN) in patients with pain caused by chronic pancreatitis. The primary goal is to determine if a 50% reduction in pain can be achieved for at least 3 months. Secondary objectives are reduction of medication use and improvement of quality of life.

Design: Single blind, prerandomized intervention study. Study population: Patients with pain (NRS>5) caused by chronic pancreatitis, despite optimal medical treatment.

Intervention: One group receives PRFLSN after a positive trial block with bupivacaine, the other group receives no extra treatment besides optimal medical treatment.

Main study endpoints: The percentage of reduction of pain after PRFLSN for a period of at least 3 months and preferably one year.

Medical and Biotech [MESH] Definitions

INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

Acute or chronic INFLAMMATION of the PANCREAS due to excessive ALCOHOL DRINKING. Alcoholic pancreatitis usually presents as an acute episode but it is a chronic progressive disease in alcoholics.

Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.

A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.

Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.
