          Abstract

          Persistent pain is a serious problem that often contributes to a poor quality of life in pancreatic cancer patients. Medical management by opioid analgesics is often accompanied by side effects and incomplete pain relief. A celiac plexus block is a simple treatment which relieves pain, but the procedure demands a certain degree of proficiency and the duration of the effects obtained can be rather limited. Transhiatal bilateral splanchnicectomy achieves a certain denervation of splanchnic nerves, but it requires a laparotomy. Unilateral thoracoscopic splanchnicectomy is a minimally invasive procedure to cause definite denervation. Bilateral thoracoscopic splanchnicectomy is recommended for unsatisfactory cases or recurrent pain occurring after the initial unilateral splanchnicectomy. It is important to select the most suitable treatment depending on patients' actual medical state and the predicted outcomes.

          Chemical splanchnicectomy in patients with unresectable pancreatic cancer. A prospective randomized trial.

          A prospective, randomized, double-blind study was completed comparing intraoperative chemical splanchnicectomy with 50% alcohol versus a placebo injection of saline in patients with histologically proven unresectable pancreatic cancer. Standardized assessment of pain, mood, and disability due to pain was completed preoperatively and at 2-month intervals until death. Chemical splanchnicectomy with alcohol was performed in 65 patients, whereas 72 patients received the placebo. The two groups were similar with respect to age, sex, location, and stage of tumor, operation performed, the use of postoperative chemo- and radiation therapy, and initial assessment scores for pain, mood, and disability. No differences in hospital mortality or complications, return to oral intake, or length of hospital stay were observed. Mean pain scores were significantly lower in the alcohol group at 2-, 4-, and 6-month follow-up and at the final assessment (p < 0.05). To further determine the effect of chemical splanchnicectomy, patients were stratified into those with and without preoperative pain. In patients without preoperative pain, alcohol significantly reduced pain scores and delayed or prevented the subsequent onset of pain (p < 0.05). In patients with significant preoperative pain, alcohol significantly reduced existing pain (p < 0.05). Furthermore, patients with preexisting pain who received alcohol showed a significant improvement in survival when compared with controls (p < 0.0001). The results suggest that intraoperative chemical splanchnicectomy with alcohol significantly reduces or prevents pain in patients with unresectable pancreatic cancer.

            Efficacy of endoscopic ultrasound-guided celiac plexus block and celiac plexus neurolysis for managing abdominal pain associated with chronic pancreatitis and pancreatic cancer.

            Endoscopic ultrasound (EUS)-guided celiac plexus block (CPB) and celiac plexus neurolysis (CPN) have become important interventions in the management of pain due to chronic pancreatitis and pancreatic cancer. However, only a few well-structured studies have been performed to evaluate their efficacy. Given limited data, their use remains controversial. Herein, we evaluate the efficacy of EUS-guided CPB and CPN in alleviating chronic abdominal pain due to chronic pancreatitis and pancreatic cancer respectively. Using Medline, Pubmed, and Embase databases from January 1966 through December 2007, a thorough search of the English literature for studies evaluating the efficacy of EUS-guided CPB and CPN for the management of chronic abdominal pain due to chronic pancreatitis and pancreatic cancer was conducted, along with a hand search of reference lists. Studies that involved less than 10 patients were excluded. Data on pain relief was extracted, pooled, and analyzed. A total of 9 studies were included in the final analysis. For chronic pancreatitis, 6 relevant studies were identified, comprising a total of 221 patients. EUS-guided CPB was effective in alleviating abdominal pain in 51.46% of patients. For pancreatic cancer, 5 relevant studies were identified with a total of 119 patients. EUS-guided CPN was effective in alleviating abdominal pain in 72.54% of patients. EUS-guided CPB was 51.46% effective in managing chronic abdominal pain in patients with chronic pancreatitis, but warrants improvement in patient selection and refinement of technique, whereas EUS-guided CPN was 72.54% effective in managing pain due to pancreatic cancer and is a reasonable option for patients with tolerance to narcotic analgesics.

              Celiac plexus neurolysis for abdominal cancer pain: a systematic review.

              This systematic review assesses the effectiveness and side effects of celiac plexus neurolysis (CPN) in the treatment of upper abdominal cancer pain, and evaluates whether there are any differences between the percutaneous and endoscopic ultrasound-guided (EUS) denervation techniques.
