ABSTRACT Videoscopic splanchnicectomy (VSPL) is a method of pain relief in chronic pancreatitis patients. Because this method is not equally effective in all patients, this study was designed to identify the factors determining the unfavorable results of VSPL.
This is a non-randomized prospective case-controlled study designed to compare a group of patients suffering from chronic pancreatitis treated with VSPL (N = 48) versus a group of patients treated symptomatically (N = 42). The outcome was measured as the intensity of pain ailments [visual analog scale (VAS)-pain scale] and subjective satisfaction of the patients from the surgical treatment [Functional Assessment of Chronic Illness Therapy-Treatment Satisfaction (FACIT-TS)]. The predictive variables considered in this study were: age, sex, emotional status, social support (the two last variables were measured by subscales of quality-of-life questionnaire from the group of FACIT), history of previous surgical treatment, and opioid use for at least 3 months before VSPL. The follow-up was 18 months. Logistic regression was performed using dichotomized pain as outcome variable: high score more than 66.7 on VAS scale and low under 50 points on VAS scale 18 months after VSPL.
VSPL significantly reduced the pain ailments at all points of the study when compared to the control. However, the pain intensity at the end of the study was higher than directly after the surgery. In the patients treated with opioids before the surgery, the pain intensity was significantly higher than in the patients not using this group of drugs. Logistic regression revealed that opioid administration before VSPL was the most important predictor of high pain scores 18 months after the surgery.
When planning the VSPL in the treatment of pain in patients suffering from chronic pancreatitis, it is necessary to take into consideration the previous chronic use of opioids, as this variable can significantly influence poorer results of this surgical pain management.

    ABSTRACT: Purpose: Patients with pancreatic malignancy suffer from intractable and persistent pain that can only be effectively treated by the use of opioids. Such pain significantly impacts quality of life and becomes the stigma of the disease and dying. The aim of the study was to evaluate the psychosocial correlates of pain among the pancreatic cancer patients, with a special emphasis on social support. Methods: One hundred and thirty one patients (52 women and 79 men) diagnosed with pancreatic cancer participated in the study. Visual Analog Scale (VAS) was used to assess current pain intensity. Social support was assessed by the subscale “Family and social living” of FACT–G and the Visual Representation Scale PRISM. Results: There was a strong correlation between pain intensity and the social support measured by subscale of FACT-G in the opioid-using group (measured by VAS r=0.47, p<0.05) and measured with the PRISM (r=0.81, p<0.05). In the opioid-naïve group, there was no relationship between pain and perceived social support level. In women, pain strongly correlated with social support: VAS/FACT correlation was r=-0.64, VAS/PRISM r=-0.62 (both p<0.05). Conclusions: In patients suffering from pancreatic cancer that use opioids, higher level of pain is connected with higher perceived positive impact of illness on social relations and with higher level of perceived social support. In contrary, in female patients, lower social support is associated with higher level of pain. Social support is an important contributor to pain perception in patients receiving opioids and in female patients.

    ABSTRACT: Chronic pancreatitis is a common disorder associated with significant morbidity and mortality. Interdisciplinary consensus guidelines have recently updated the definitions and diagnostic criteria for chronic pancreatitis and provide a critical assessment of therapeutic procedures. Diagnostic imaging relies on endoscopic ultrasound (EUS) as the most sensitive technique, whereas computed tomography (CT) and magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP) remain a frequent preoperative requirement. Endoscopic retrograde cholangiopancreatography (ERCP) is now used mostly as a therapeutic procedure except for the differential diagnosis of autoimmune pancreatitis. Complications of chronic pancreatitis, such as pseudocysts, duct stricture and intractable pain can be treated with endoscopic interventions as well as open surgery. In the treatment of pseudocysts endoscopic drainage procedures now prevail while pain treatment has greater long-term effectiveness following surgical procedures. Currently, endocopic as well as surgical treatment of chronic pancreatitis require an ever increasing degree of technical and medical expertise and are provided increasingly more often by interdisciplinary centres. Surgical treatment is superior to interventional therapy regarding the outcome of pain control and duodenum-preserving pancreatic head resection is presently the surgical procedure of choice.

    ABSTRACT: Thoracoscopic splanchnicectomy (TS) is a minimally invasive intervention to relieve pain in patients with chronic pancreatitis (CP) with equivocal results. Preoperative opioid use seems to impair TS outcome but this has not been investigated in a systematic matter. We searched PubMed, EMBASE, and The Cochrane Library for studies on the outcome of TS in CP patients. Studies with ≥5 patients and a follow-up of ≥12 months were included. Success was defined as the proportion of patients free of opioids or who had a reduction of ≥4 points on a pain scale. The effect of opioid use on the success rate of TS was analyzed by uni- and multivariate regression. Sixteen studies with 484 patients were included in our review. The mean (±SD) age of the patients was 44 ± 4.3 years and 66 % were male. Median follow-up period was 21 months (IQR 14-35). Median preoperative opioid use was 85 % (IQR 54-100 %). After TS, a median of 49 % (IQR 22-75 %) of patients were free of opioids at end of follow-up. The median success rate was 62 % (IQR 48-86 %). Mean success rate in studies in which ≤50 % of the patients used opioids preoperatively was 81 % (SD ± 21) compared to 60 % (SD ± 15) for other studies (p = 0.049). Higher age, male gender, and lower rates of preoperative opioid use were associated with a higher success rate (p = 0.003, 0.047, and 0.017, respectively). Multivariate regression, including age, gender, preoperative opioid use, and duration of follow-up, identified age and preoperative opioid use as independent predictors of success after TS (both p = 0.002). Preoperative opioid use is associated with a worse outcome after TS in CP patients. To optimize outcome, use of TS may be considered at an earlier stage in the treatment of patients with CP before prolonged opioid therapy.
