Abstract
Abdominal pain secondary to chronic pancreatitis (CP) is difficult to manage and often requires chronic oral opioid therapy (OOT). Targeted drug delivery (TDD) allows for a diminished dose of opioid intake and improved pain levels. TDD has been used in different pain syndromes with only limited reports in CP. OBJECTIVE The objective of this article is to perform a retrospective review of CP patients treated with TDD versus OOT to compare chronic pain control and consumed morphine-equivalent doses. METHODS Patients receiving TDD between September 2011 and August 2018 were included. All patients were weaned off oral opioids one week before intrathecal trial and pump implantation. Patients with intrathecal trials providing at least 50% pain relief underwent pump implantation. Data were collected while on OOT and at two weeks, three months, and nine months post-implant. Data were analyzed with Microsoft Excel 365 MSO using means and standard deviations. P-values were calculated using a two-tailed student's t-test with paired two-sample means. RESULTS Twenty-three patients were analyzed. Pre-trial average pain score was 6.5/10 with a mean improvement with trials greater than 71%. The mean chronic baseline oral morphine milligram equivalents (MME) was 188. The mean MME on TDD at two weeks (0.36), three months (1.39), and nine months (2.47) were significantly lower than OOT. Mean pain scores were 6, 4.9, and 5.6 at two weeks, three months, and nine months, respectively, compared to 6.5 on OOT. DISCUSSION The results of this study indicate that TDD provides improved pain control with significantly lower opioid doses.

Abstract
Visceral pain is a complex and heterogeneous pain condition that is often associated with pain-related negative emotional states, including anxiety and depression, and can exert serious effects on a patient's physical and mental health. According to modeling stimulation protocols, the current animal models of visceral pain mainly include the mechanical dilatation model, the ischemic model, and the inflammatory model. Acupuncture can exert analgesic effects by integrating and interacting input signals from acupuncture points and the sites of pain in the central nervous system. The brain nuclei involved in regulating visceral pain mainly include the nucleus of the solitary tract, parabrachial nucleus (PBN), locus coeruleus (LC), rostral ventromedial medulla (RVM), anterior cingulate cortex (ACC), paraventricular nucleus (PVN), and the amygdala. The neural circuits involved are PBN-amygdala, LC-RVM, amygdala-insula, ACC-amygdala, claustrum-ACC, bed nucleus of the stria terminalis-PVN and the PVN-ventral lateral septum circuit. Signals generated by acupuncture can modulate the central structures and interconnected neural circuits of multiple brain regions, including the medulla oblongata, cerebral cortex, thalamus, and hypothalamus. This analgesic process also involves the participation of various neurotransmitters and/or receptors, such as 5-hydroxytryptamine, glutamate, and enkephalin. In addition, acupuncture can regulate visceral pain by influencing functional connections between different brain regions and regulating glucose metabolism. However, there are still some limitations in the research efforts focusing on the specific brain mechanisms associated with the effects of acupuncture on the alleviation of visceral pain. Further animal experiments and clinical studies are now needed to improve our understanding of this area.

Abstract
OBJECTIVE Aim: To analyze the state of parameters of inflammation, endotoxicosis, and their influence on the functional capacity of the pancreas in the comorbid course of chronic pancreatitis and type 2 diabetes mellitus (DM2). PATIENTS AND METHODS Materials and methods: 115 patients with CP in the phase of mild therapeutic exacerbation in combination with DM2 in the stage of subcompensation were examined. To assess the impact of comorbid DM2 on the clinical condition of patients with CP, a comparison group of 25 patients with CP in the exacerbation phase was included in the study. The assessment of the presence and depth of pancreatic exocrine insufficiency (PEI) was carried out according to the "gold standard" - determination of the content of fecal α-elastase-1, which was determined by the method of enzyme immunoassay using standard kits. As the main criterion for diagnosis and monitoring of DM, the measurement of HbA1c was used, which was determined by the method of ion exchange chromatography. C-reactive protein (CRP) was determined by the immunoturbidometry method by photometric measurement of the antigen-antibody reaction to human CRP antibodies; reference values of CRP in blood serum are up to 3 mg/l. Endogenous intoxication (EI) was assessed based on the levels of medium-mass molecules (MMM) - MMM1 and MMM2 at wavelengths 254 and 280 nm. The level of circulating immune complexes (CIC) was determined by the method of selective precipitation in 3.75% ethylene glycol followed by photometry. RESULTS Results: Moderate and moderate inverse correlations were established between CRP and fecal α-elastase in CP and CP-DM2 comorbidity (r=-0.423 and r=-0.565, p<0.05). This proved a reliable influence of the depth of inflammation according to the content of CRP on the increase in PEI according to the level of fecal α-elastase, which was higher in the CP-DM2 comorbidity compared to CP. A deeper level of secretory insufficiency of the pancreas was established in CP with concomitant DM2, which deepened when the CRP level increased, compared to that in isolated CP: an increase in the strength of reliable direct moderate HbA1c-CRP correlations in patients with CP in combination with DM2 was proved in relation to such cases isolated CP (respectively r=0.313 and r=0.410, p<0.05). CONCLUSION Conclusions: We proved a reliable influence of the index of endogenous intoxication on the level of PEI according to the level of fecal α-elastase, which was higher in the CP-DM2 comorbidity compared to isolated CP: moderate and medium-strength inverse correlations were established IEI-fecal α-elastase in patients with CP and CP-DM2 comorbidity (r=-0.471 and r=-0.517, p<0.05). An increase in the strength of reliable direct, moderate, and moderate correlations between the levels of HbA1c and the index of endogenous intoxication in patients with isolated CP and CP-DM2 comorbidity (r=0.337 and r=0.552, p<0.05), which proved a deeper level of secretory pancreas insufficiency with concomitant DM2, which worsened with increasing endotoxicosis according to the value of the index of endogenous intoxication.

Abstract
A thorough pain assessment is of utmost importance when managing pain in clinical practice as it is the foundation for defining pain in need of treatment, either interventional or pharmacological. Pain characteristics can also guide interventional strategies and help evaluate the effect of treatment. In research settings, standardized pain assessment is crucial to improve comparability across studies and facilitate meta-analysis. Due to the importance of thorough visceral pain assessment, this manuscript describes the key elements of pain evaluation focusing on chronic pancreatitis. Most studies in pain assessment have focused on somatic pain, and although chronic pain often shares characteristics between etiologies, some differences must be addressed when assessing visceral pain. Especially differences between somatic and visceral pain are apparent, where visceral pain is diffuse and difficult to localize, with referred pain aspects and often autonomic symptoms dominating the clinical picture. These aspects need to be incorporated into the pain assessment instrument. The manuscript will discuss the different ways of assessing pain, including unidimensional measurement scales, multidimensional questionnaires, and quantitative sensory testing. The advantages and challenges linked to the different methods will be evaluated.

Pancreatic QST Differentiates Chronic Pancreatitis Patients into Distinct Pain Phenotypes Independent of Psychiatric Comorbidities. Clin Gastroenterol Hepatol 2022; 20:153-161.e2.

Abstract
BACKGROUND & AIMS Quantitative sensory testing (QST) has been previously used to study pain in chronic pancreatitis (CP) but included methods that are not suitable for clinical purposes. The aims of this study were to determine if pancreatic QST (P-QST) can differentiate patients into distinct pain phenotypes and to determine the association of these with their clinical pain and psychiatric comorbidities. METHODS A multicenter cross-sectional study was conducted where patients completed validated questionnaires assessing quality of life (QoL), depression and anxiety scores as well as clinical pain symptoms followed by P-QST which included a cold pressor test, repetitive pinprick stimuli and pressure stimulation of the upper abdominal (T10) and control dermatomes. P-QST categorized patients into pain phenotypes based on a previously established nomogram. QoL, clinical pain and psychiatric assessment scores were compared across these groups. RESULTS A total of 179 patients were enrolled with a mean age of 54.1±13.6 years among whom 59% were males and 42% had an alcoholic etiology. P-QST showed no hyperalgesia in 91 (51%), segmental hyperalgesia in 50 (28%) and widespread hyperalgesia in 38 (21%) patients. Patients with widespread hyperalgesia had significantly higher pain intensity scores (P = .03) and rates of constant pain (P = .002) as well as decreased QoL (P < .001) and physical functioning (P =.03) in comparison with the other two pain phenotypes. In contrast, psychiatric comorbidities were similar across all groups. CONCLUSIONS P-QST may serve as a novel unbiased pain assessment tool in CP as it categorizes patients into distinct pain phenotypes independent of their psychiatric comorbidities.

Abstract
OBJECTIVES Abdominal pain is the primary symptom of chronic pancreatitis (CP), but pain is difficult to assess, and objective methods for pain assessment are lacking. The characterization of the sensory component of pain as a surrogate for nociception can be achieved by sensory testing using standardized stimuli. Herein, we describe the rationale for and development of an international consortium to better understand and characterize CP pain. METHODS A collaboration was initially formed between the University of Aalborg, Johns Hopkins University, and the University of Pittsburgh. This group refined the protocol for pancreatic quantitative sensory testing (P-QST) and then expanded the collaboration with plans for incorporating P-QST into prospective studies. RESULTS The collaboration has successfully developed a P-QST nomogram. Chronic pancreatitis patients identified with P-QST as having widespread hyperalgesia had higher pain intensity scores, higher prevalence of constant pain, and decreased quality of life. Psychiatric comorbidities were independent of pain phenotypes. Multiple studies are underway to validate these findings and evaluate their utility in clinical trials. CONCLUSIONS Development of the P-QST Consortium will facilitate collaborative efforts to use P-QST as a means for evaluation and characterization of pain in CP patients, and optimize methods to guide individualized pain management approaches.

Assessment of pain associated with chronic pancreatitis: An international consensus guideline. Pancreatology 2021; 21:1256-1284.

Abstract
Pain is the most common symptom in chronic pancreatitis (CP) with a major impact on quality of life. Few validated questionnaires to assess pain in CP exist, and the lack of consensus negatively impacts clinical management, research and meta-analysis. This guideline aims to review generic pain questionnaires for their usability in CP, to outline how pain assessment can be modified by confounding factors and pain types, to assess the value of additional measures such as quality of life, mental health and quantitative sensory testing, and finally to review pain assessment questionnaires used specifically in CP. A systematic review was done to answer 27 questions that followed the PICO (Population; Intervention; Comparator; Outcome) template. Quality of evidence of the statements was judged by Grades of Recommendation, Assessment, Development and Evaluation (GRADE) criteria. The manuscript was sent for review to 36 experts from various disciplines and continents in a multi-stage Delphi process, and finally reviewed by patient representatives. Main findings were that generic pain instruments are valid in most settings, but aspects of pain are specific for CP (including in children), and instruments have to account for the wide phenotypic variability and development of sensitization of the central nervous system. Side effects to treatment and placebo effects shall also be considered. Some multidimensional questionnaires are validated for CP and are recommended together with assessment of quality of life and psychiatric co-morbidities. This guideline will result in more homogeneous and comprehensive pain assessment to potentially improve management of painful CP.

Abstract
OBJECTIVE This study analyzes the clinicopathologic findings and their impact on outcome of patients so as to identify which patients benefit most from surgical treatment in chronic pancreatitis, especially in regard to pain relief. SUMMARY BACKGROUND DATA The predominant symptom of chronic pancreatitis is chronic pain resulting in reduced quality of life. It is well known that the main reason for development of the disease is abuse of alcohol and nicotine, but only little data on factors influencing outcome are available. METHODS One thousand one hundred forty-six consecutive patients who underwent surgery for chronic pancreatitis were included. Clinicopathologic data, including morphology of the pancreas in preoperative diagnostics and the histopathologic results, were evaluated. A long-term follow-up including Quality of Life and pain scores was performed. Additionally, we describe the novel Chronic Pancreatitis Pain Relief Score (CPPR-Score) as a tool for prediction of pain relief. RESULTS Overall the rate of pain relief was 79.8% after surgery. The presence of an inflammatory mass in the pancreatic head larger than 4 cm (P < 0.001), presence of a dilated main pancreatic duct of over 4 mm (P < 0.001), histopathologically detected severe calcifications (P = 0.001) and severe fibrosis (P < 0.001) as well as ethanol induced disease (P < 0.001) found to be strong independent prognostic factors for pain relief. The CPPR-Score (0-5 points) proved to be a very good predictive score for pain-relief (P < 0.001). CONCLUSIONS The rate of pain relief after surgical treatment in chronic pancreatitis is high and the commonly used procedures can be performed with acceptable morbidity and mortality. The Chronic Pancreatitis Pain Relief Score allows identifying patients who will benefit most from surgery.

Abstract
Pain is the main clinical symptom of chronic pancreatitis (CP), as well as the most common cause of patients' recurrent hospitalizations. The management regimen for CP pain needs to be formulated according to the patient's conditions. Lifestyle changes and drug treatment can usually be used as first-line therapy. Conventional analgesics, pancreatic enzymes, and antioxidants are commonly used in treating pain of CP. In recent years, the application of conventional analgesics has been further standardized. Besides, there have been more clinical studies on the treatment of CP pain with pancreatic enzymes or antioxidants. Traditional Chinese medicine has played an increasingly important role in the treatment of CP pain. New drugs such as camostat mesylate are expected to be used in CP pain, though more high-quality studies are still needed to confirm their safety and effectiveness.

Abstract
Chronic pancreatitis affects over 250,000 people in the US and millions worldwide. It is associated with chronic debilitating pain, pancreatic exocrine failure, and high risk of pancreatic cancer and usually progresses to diabetes. Treatment options are limited and ineffective. We developed a new potential therapy, wherein a pancreatic ductal infusion of 1%-2% acetic acid in mice and nonhuman primates resulted in a nonregenerative, near-complete ablation of the exocrine pancreas, with complete preservation of the islets. Pancreatic ductal infusion of acetic acid in a mouse model of chronic pancreatitis led to resolution of chronic inflammation and pancreatitis-associated pain. Furthermore, acetic acid-treated animals showed improved glucose tolerance and insulin secretion. The loss of exocrine tissue in this procedure would not typically require further management in patients with chronic pancreatitis because they usually have pancreatic exocrine failure requiring dietary enzyme supplements. Thus, this procedure, which should be readily translatable to humans through an endoscopic retrograde cholangiopancreatography (ERCP), may offer a potential innovative nonsurgical therapy for chronic pancreatitis that relieves pain and prevents the progression of pancreatic diabetes.

Abstract
There is tremendous interpatient variability in the response to analgesic therapy
(even for efficacious treatments), which can be the source of great frustration
in clinical practice. This has led to calls for “precision
medicine” or personalized pain therapeutics (ie, empirically based
algorithms that determine the optimal treatments, or treatment combinations, for
individual patients) that would presumably improve both the clinical care of
patients with pain and the success rates for putative analgesic drugs in phase 2
and 3 clinical trials. However, before implementing this approach, the
characteristics of individual patients or subgroups of patients that increase or
decrease the response to a specific treatment need to be identified. The
challenge is to identify the measurable phenotypic characteristics of patients
that are most predictive of individual variation in analgesic treatment
outcomes, and the measurement tools that are best suited to evaluate these
characteristics. In this article, we present evidence on the most promising of
these phenotypic characteristics for use in future research, including
psychosocial factors, symptom characteristics, sleep patterns, responses to
noxious stimulation, endogenous pain-modulatory processes, and response to
pharmacologic challenge. We provide evidence-based recommendations for core
phenotyping domains and recommend measures of each domain.

Background Pain is the primary symptom of chronic pancreatitis (CP) and remains a considerable therapeutic challenge. In patients with obstruction of the pancreatic duct, including stones and strictures, endoscopic treatment with or without preceding extracorporeal shock wave lithotripsy (ESWL) has been used for pancreatic duct decompression. The rationale for these procedures is based on the assumption that obstruction of the pancreatic duct leads to ductal hypertension and pain. However, clinical pain symptoms correlate poorly with pancreatic duct morphology, and the evidence for pancreatic duct decompression as an effective treatment for pain is based on case series and comparison between different procedures. No randomized, prospective, sham-controlled trials are currently available. The SCHOKE (Extracorporeal Shock Wave Lithotripsy and Endotherapy for Pain in Chronic Pancreatitis) trial is a randomized, sham-controlled trial designed to determine if pancreatic duct decompression is an effective treatment for pain in patients with CP. Methods The SCHOKE trial is a randomized, single-blind, parallel-group, sham-controlled trial designed to evaluate the effect of combined ESWL and endoscopic treatment for pain in patients with CP. In total, 106 adult patients with painful CP and pancreatic duct obstruction will be randomized to combined ESWL and subsequent endoscopic treatment or corresponding sham procedures. The primary outcome is pain relief during the 3-month postrandomization period as documented in a pain diary. Secondary outcomes include quality of life and functional scores, patient global impression of change, change in use of analgesics, frequency of hospitalization, and complications. Standard follow-up is at 3 and 6 months after randomization. In an experimental substudy, quantitative sensory testing obtained before and after intervention will be used to obtain information on central pain processing and to develop models for prediction of treatment outcome. Discussion The SCHOKE trial investigates if pancreatic duct decompression, obtained by combined ESWL and endoscopic treatment, is effective for pain treatment in patients with CP.

Abstract
Chronic pancreatitis is characterized by progressive, irreversible morphologic and functional changes that are most commonly attributed to environmental insults, particularly when there is a genetic or anatomic predisposition. Heavy alcohol use and cigarette smoking are the most common environmental risk factors, but both may be absent. Antecedent episodes of acute pancreatitis occur in about half of patients. Abdominal pain is the most common symptom and requires a tailored approach depending on the anatomic changes in the pancreas. Other clinical manifestations include diabetes mellitus, exocrine pancreatic insufficiency, metabolic bone disease, pancreatic cancer, and anatomic complications. Current disease management is centered on risk factor reduction and screening for and treating disease complications. There are no current therapies to delay or retard disease progression, but there are ongoing efforts to more fully understand the natural history of chronic pancreatitis and underlying mechanisms of disease. These studies are expected to provide insights that will transform our approach to disease management and provide increased hope to patients.

Abstract
OBJECTIVE Pain is a common and disabling symptom in patients with leg ulcers. Clinical quantification of pain mostly depends on subjective pain reports, which do not reveal underlying mechanisms. The aim of this pilot study is to identify mechanisms underlying the pain in patients with leg ulcers by documenting alterations in pain processing using quantitative sensory testing. METHODS In nine ulcer patients the mechanical sensory thresholds and the mechanical pain thresholds were determined by Semmes-Weinstein monofilaments (SWM) at three different sites: on the contralateral (unaffected) leg, on the skin of the affected leg 10cm from the ulcer margin, and on the affected leg, close (1-2cm) to the ulcer margin. Besides the mechanical sensory thresholds and mechanical pain thresholds, pain at the site of the ulcer, using an 11-point numeric rating scale (NRS), was documented. RESULTS Mechanical sensory thresholds were increased in all subjects. Almost half (44%) of patients consistently showed allodynia at the unaffected site. The lowering of mechanical pain thresholds correlated with higher scores on the NRS. CONCLUSION All patients showed diminished touch and/or protective sensation, which might have contributed to ulcer development via (partial) loss of protective function. The allodynia at the unaffected site suggests the presence of central sensitisation of pain processing.

Abstract
OBJECTIVE Abnormal pain processing in the central nervous system is a hallmark of chronic pancreatitis (CP). We characterized brain structure in CP patients and identified disease characteristics that impact the brain structure in CP patients. PATIENTS AND METHODS Thirty-three CP patients and 23 matched healthy controls underwent brain MRI. Total and regional gray matter volume (GMV) and cortical thickness analyses were carried out. Multivariate linear regression models were used to determine the independent predictors of total GMV. RESULTS CP patients had 31.9 ± 9.3 ml (mean ± SE) (5.1%) reduced total GMV compared with the healthy controls (587.1 ± 5.8 vs. 619.0 ± 7.0 cm, P < 0.001). Alcoholic etiology was associated independently with a decreased total GMV (P < 0.001), whereas no association was observed for pain or other disease characteristics (all P > 0.05). Similarly, regional GMV loss and cortical thinning were observed for several cortical areas in patients with alcoholic etiology compared with their nonalcoholic counterparts (P < 0.05). These regional differences were particularly evident for pain-related cortical areas; however, no significant differences in regional GMV or cortical thickness were observed between patients with and without pain (all P > 0.05). CONCLUSION Patients with CP have GMV loss that is associated with alcoholic disease etiology. No associations were detected between pain and GMV loss, likely because the potential effect of long-lasting pain on brain structure is masked by the effects of previous alcohol use. The findings imply that alcoholic etiology is the most prominent contributing factor for structural brain alterations in CP patients.

Abstract
INTRODUCTION Chronic pancreatitis (CP) is thought to present the end stage of a continuous disease process evolving from acute pancreatitis (AP), over recurrent AP, to early and end-stage CP. Due to the irreversible nature of CP, early detection and prevention is key. Prospective assessment based on advanced imaging modalities as well as biochemical markers of inflammation, fibrosis and oxidative stress may provide a better understanding of the underlying pathological processes and help identify novel biomarkers of disease with the ultimate goal of early diagnosis, intervention and prevention of disease progression. This paper describes the protocol of a prospective multicentre cohort study investigating the fibroinflammatory process involved in progression from acute to CP using state-of-the-art diagnostic imaging modalities and circulating biomarkers of inflammation, fibrosis and oxidative stress. METHODS AND ANALYSIS Adult control subjects and patients at different stages of CP according to the M-ANNHEIM system will be recruited from outpatient clinics at the participating sites and form three cohorts: controls (n=40), suspected CP (n=60) and definitive CP (n=60). Included patients will be followed prospectively for 15 years with advanced MRI and contrast-enhanced endoscopic ultrasound with elastography, assessment of endocrine and exocrine pancreatic function, biochemical and nutritional assessment, and evaluation of pain processing using quantitative sensory testing. Blood samples for a biobank will be obtained. The purpose of the biobank is to allow analyses of potential circulating biomarkers of disease progression, including markers of inflammation, fibrosis and oxidative stress. ETHICS AND DISSEMINATION Permissions from the Regional Science Ethics committee and the Regional Data Protection Agency have been obtained. We will submit the results of the study for publication in peer-reviewed journals regardless of whether the results are positive, negative or inconclusive.

Abstract
Background Assessing features of centralized pain may prove to be clinically meaningful in pediatric populations. However, we are currently limited by the lack of validated pediatric measures. Aim We examined the psychometric properties of the Widespread Pain Index (WPI) and Symptom Severity (SS) scale, to assess features of centralized pain, in youth with painful conditions from three clinical samples: (1) musculoskeletal surgery, (2) headache, and (3) chronic pain. Methods Participants were 240 youth aged 10-18 years (Mage=14.8, SD=1.9) who completed the WPI and SS scale. Subsets of participants also completed additional measures of pain region, pain intensity, quality of life, pain interference and physical function. Results Increased features of centralized pain by age were seen for the WPI (r=0.27, p<0.01) and SS scale (r=0.29, p<0.01). Expected differences in sex were seen for the WPI (sex:t132=-3.62, p<0.01), but not the SS scale (sex:t223=-1.73, p=0.09). Reliability for the SS scale was adequate (α=.70). Construct validity was demonstrated through relationships between the WPI and pain regions (r=.57, p<0.01), and between the SS scale and quality of life (r=-.59, p<0.01) and pain interference (r=.56, p<0.01). Criterion validity was demonstrated by differences on the WPI between the surgery sample and the headache and chronic pain samples (F2,237=17.55, p<0.001). Comprehension of the SS scale items was problematic for some youth. Conclusions The WPI showed adequate psychometric properties in youth; however the SS scale may need to be modified. Our findings support the need to develop psychometrically sound instruments for comprehensive assessment of pain in pediatric samples.

Abstract
Chronic pancreatitis is a chronic inflammation of the pancreas with pain as its severest symptom and often an impaired quality of life. Surgical intervention plays an important role in the management of pain but is generally kept as a last resort when conservative measures and endoscopy have failed. However, in the last few years multiple studies suggested the superiority of (early) surgical treatment in chronic pancreatitis for multiple end points, including pain relief. In this paper we highlight the most recent high-quality evidence on surgical therapy in chronic pancreatitis and the rationale for early (surgical) intervention.

Abstract
INTRODUCTION Previous studies suggest that fragmentation of pancreatic duct stones (PDS) using extracorporeal shock wave lithotripsy (ESWL) is associated with pain relief. However, the treatment may not be effective in certain subgroups. AIM To evaluate predictors of pain relief after ESWL in patients with chronic pancreatitis and PDS. METHODS Retrospective study including patients with chronic pancreatitis undergoing ESWL for painful PDS. Analgesic use before and after the ESWL procedure was registered. We defined adequate pain relief after ESWL as 'pain-free without analgesics or with use of weak analgesics as needed'. The study was approved by the Danish Data Protection Agency (approval number: AHH-2017-048). RESULTS We included 81 patients (median age 58 years; 63% men; 68% alcoholic pancreatitis). Patients underwent one to seven ESWL procedures (mean 1.7). A concurrent ERCP was performed in 17%. All patients used analgesics before the ESWL procedure (68 used opioids). After ESWL, 43 still used opioids. Thirty-two patients achieved adequate pain relief. Univariable regression analysis showed that older age predicted adequate pain relief (OR 1.09;1.03-1.16; p = .002) as did location of the stone in the head or neck (OR 2.59;1.04-6.45; p = .041). In multivariable analysis, we found that the only two predictors of adequate pain relief were age (p = .002) and the location of the stones (p = .039). CONCLUSION After the ESWL, about four out of ten patients are pain-free without medication or able to manage their pain with weak analgesics. Age and the location of the stones may be considered when evaluating if patients are eligible for referral to ESWL.

Abstract
Background The assessment of a neuropathic pain component (NePC) to establish the neurological criteria required to comply with the clinical description is based on history taking, clinical examination, and quantitative sensory testing (QST) and includes bedside examination (BSE). The objective of this study was to assess the potential association between the clinically diagnosed presence or absence of an NePC, BSE, and the Nijmegen–Aalborg screening QST (NASQ) paradigm in patients with chronic (≥3 months) low back and leg pain or with neck shoulder arm pain or in patients with chronic pain due to suspected peripheral nerve damage. Methods A total of 291 patients participated in the study. Pain (absence or presence of neuro-pathic pain) was assessed independently by two physicians and compared with BSE (measurements of touch [finger, brush], heat, cold, pricking [safety pin, von Frey hair], and vibration). The NASQ paradigm (pressure algometry, electrical pain thresholds, and conditioned pain modulation) was assessed in 58 patients to generate new insights. Results BSE revealed a low association of differences between patients with either absent or present NePC: heat, cold, and pricking sensations with a von Frey hair were statistically significantly less common in patients with present NePC. NASQ did not reveal any differences between patients with and without an NePC. Conclusion Currently, a standardized BSE appears to be more useful than the NASQ paradigm when distinguishing between patients with and without an NePC.

Abstract
OBJECTIVES We investigated the impact of patient age and disease duration on islet isolation results, diabetes outcomes, and pain outcomes after total pancreatectomy with islet autotransplant (TPIAT) performed in 64 patients with hereditary pancreatitis due to PRSS1 gene mutation. METHODS We evaluated the association of patient age and disease duration on islet isolation results and opioid use at 1 year using logistic regression and on graft function using 1-way analysis of variance. RESULTS Islet mass was negatively associated with increasing age and longer disease duration, with a 13% reduction (95% confidence interval [CI], 3%-22%) and 22% (95% CI, 14%-29%) reduction in islet equivalents per kilogram body weight (IEQ/kg) for each 5 years of age and disease duration, respectively. Full graft function was associated with younger age and shorter duration of disease (P < 0.01). Persistent opioid use (15% of patients at 1 year) increased with age (P = 0.05) and disease duration (P = 0.04). CONCLUSIONS The TPIAT outcomes were adversely impacted by older age and prolonged disease. In particular, islet mass is lower and risk of diabetes high in older patients with prolonged disease. This should be considered when counseling this subgroup of TPIAT recipients on expected outcomes.

HPB (Oxford) 2018; 20:166-174. [PMID: 28993044 DOI: 10.1016/j.hpb.2017.08.033] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Revised: 07/09/2017] [Accepted: 08/30/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Little published data exist examining causes of hospital readmission following total pancreatectomy with islet autotransplantation (TPIAT). METHODS A retrospective analysis was performed of a prospectively collected institutional TPIAT database. Primary outcome was unplanned readmission to the hospital within 30 days from discharge. Reasons and risk factors for readmission as well as islet function were evaluated and compared by univariate and multivariate analysis. RESULTS 83 patients underwent TPIAT from 2006 to 2014. 21 patients (25.3%) were readmitted within 30 days. Gastrointestinal problems (52.4%) and surgical site infection (42.8%) were the most common reasons for readmission. Initial LOS and reoperation were risk factors for early readmission. Patients with delayed gastric emptying (DGE) were three times more likely to get readmitted. In multivariate analysis, patients undergoing pylorus preservation surgery were nine times more likely to be readmitted than the antrectomy group. CONCLUSION Early readmission after TPIAT is common (one in four patients), underscoring the complexity of this procedure. Early readmission is not detrimental to islet graft function. Patients undergoing pylorus preservation are more likely to get readmitted, perhaps due to increased incidence of delayed gastric emptying. Decision for antrectomy vs. pylorus preservation needs to be individualized.

Abstract
AIM To evaluate the endoscopic treatment efficacy and prognostic factors of long-term response to treatment for painful chronic pancreatitis.
METHODS This retrospective analysis identified 168 patients with painful chronic pancreatitis hospitalized during January 2010-January 2015 in a Romanian tertiary referral center. Data on demographics, medical history, alcohol consumption, smoking habit, clinical parameters, type and number of endoscopic procedures and hospital admissions number were collected from the medical charts and analyzed. The absence or substantial reduction of pain (mild pain) at the end of the follow-up associated with the technical success of endotherapy was considered as clinical success.
RESULTS Among the 168 patients with painful chronic pancreatitis admitted to our department during the study period, 39 (23.21%) had optimal response to the medical therapy. One hundred and twenty-nine patients required endoscopic treatment. The median follow-up period was 15 mo (range, 0-60 mo). Overall, technical success of endotherapy was achieved in 105 patients (81.39%). More than two-thirds of patients (82.78%) had substantial improvement of pain after the endoscopic treatment, including frequency and severity of the pain attacks. Patients younger than 40 years had significantly more successful endoscopic procedures (P = 0.041). Clinical success was higher in non-smoking patients (P = 0.003). The hospital admission rate was higher in patients with recognized alcohol consumption (P = 0.03) and in smokers (P = 0.027). The number and location of pancreatic stones and locations of strictures did not significantly influence the technical success (P > 0.05) or the clinical success (P > 0.05).
CONCLUSION Younger age than 40 years can be considered an important factor positively influencing endoscopic treatment outcome in patients with painful chronic pancreatitis.

Total Pancreatectomy With Islet Autotransplantation for Acute Recurrent and Chronic Pancreatitis. ACTA ACUST UNITED AC 2017; 15:548-561.

Abstract
PURPOSE OF REVIEW The first total pancreatectomy and islet autotransplantation (TP-IAT) was performed for chronic pancreatitis in 1977 with the goal to ameliorate the pain and simultaneously preserve islet function. We reviewed the recent medical literature regarding indications, patient suitability, current outcomes, and challenges in TP-IAT. RECENT FINDINGS Current indications for TP-IAT include intractable pain secondary to chronic pancreatitis (CP) or acute recurrent pancreatitis (ARP) with failed medical and endoscopic/surgical management. Independent studies have shown that TP-IAT is associated with elimination or significant improvement in pain control and partial or full islet graft function in the majority of patients. In single-center cost analyses, TP-IAT has been suggested to be more cost-effective than medical management of chronic pancreatitis. While initially introduced as a surgical option for adults with long-standing chronic pancreatitis, TP-IAT is now often utilized in children with chronic pancreatitis and in children and adults with intractable acute recurrent pancreatitis. The surgical procedure has evolved over time with some centers offering minimally invasive operative options, although the open approach remains the standard. Despite many advances in TP-IAT, there is a need for further research and development in disease diagnosis, patient selection, optimization of surgical technique, islet isolation and quality assessment, postoperative patient management, and establishment of uniform metrics for data collection and multicenter studies. TP-IAT is an option for patients with otherwise intractable acute recurrent or chronic pancreatitis which presents potential for pain relief and improved quality of life, often with partial or complete diabetes remission.

Abstract
Abdominal pain is the foremost complication of chronic pancreatitis (CP). Pain can be related to recurrent or chronic inflammation, local complications or neurogenic mechanisms with corresponding changes in the nervous systems. Both pain intensity and the frequency of pain attacks have been shown to reduce quality of life in patients with CP. Assessment of pain follows the guidelines for other types of chronic pain, where the multidimensional nature of symptom presentation is taken into consideration. Quantitative sensory testing may be used to characterize pain, but is currently used in a research setting in advanced laboratories. For pain relief, current guidelines recommend a simple stepwise escalation of analgesic drugs with increasing potency until pain relief is obtained. Abstinence from alcohol and smoking should be strongly advised. Pancreatic enzyme therapy and antioxidants may be helpful as initial treatment. Endoscopic treatment can be used in patients with evidence of ductal obstruction and may be combined with extracorporeal shock wave lithothripsy. The best candidates are those with distal obstruction of the main pancreatic duct and in early stage of disease. Behavioral interventions should be part of the multidisciplinary approach to chronic pain management particularly when psychological impact is experienced. Surgery should be considered early and after a maximum of five endoscopic interventions. The type of surgery depends on morphological changes of the pancreas. Long-term effects are variable, but high success rates have been reported in open studies and when compared with endoscopic treatment. Finally, neurolytical interventions and neuromodulation can be considered in difficult patients.

Abstract
BACKGROUND/OBJECTIVES Chronic pancreatitis (CP) pain is challenging to treat. Treatment selection is hampered by there being no validated pain assessment tool that accounts for the complexity of CP pain and its underlying mechanisms. This study aims to develop a comprehensive pain assessment tool (COMPAT) specific for CP, evaluate its face validity with experts and patients and test it with a pilot cohort of patients. METHODS COMPAT was developed from existing pain assessment tools and a literature review. Face validity was conducted by pancreatologists and CP patients using an item-content validity index for importance, relevance and clarity. Subsequent revisions were made to COMPAT. A pilot cohort of CP patients tested COMPAT. RESULTS COMPAT was developed and covered all important aspects of CP pain. Experts and CP patients reported that 70% of questions were important and relevant to CP pain. Most experts were willing to use COMPAT in clinic, ward/hospital and research settings. The most common location of pain was the epigastrium and food was the most important trigger. Pain Pattern C (constant background pain with pain attacks), had significantly higher frequency of pain attacks, higher opioid use, and affective descriptors of pain than Pattern A (pain attacks with no background pain). CONCLUSIONS COMPAT has high face validity and met with high acceptance. CP patients successfully self-reported their pain with COMPAT. The results reveal many differences in the CP pain within the pilot cohort, which may reflect different mechanisms of pain. A larger prospective cohort study is planned to further validate COMPAT.

Abstract
The medical management of pain in chronic pancreatitis continues to pose significant challenges for clinicians caring for these patients. There are increasing data, suggesting that pain in chronic pancreatitis is largely due to peripheral and central sensitization that evolves, over time, as a result of nociceptive afferent associated with chronic inflammation and fibrosis of the pancreas. In many instances, patients rapidly progress to requiring opioid analgesics for the adequate treatment of pain despite the unequivocal risks associated with the long-term use of these drugs. Centrally acting drugs, such as gabapentinoids, appear to be effective means of treating pain due to their inhibition of neurotransmitters involved in central sensitization, but side effects limit their use. The present review explores the evidence for various non-pharmacologic and pharmacologic treatments for pain in chronic pancreatitis.

Abstract
Background The effective management of pain in chronic pancreatitis (CP) remains a therapeutic challenge. Analgesic drugs, such as opioids, and the underlying pathology can impair gut function. The autonomic nervous system influences hormone secretion and gut motility. In healthy volunteers, electrical (using noninvasive transcutaneous vagal nerve stimulation [t-VNS]) and physiological (using deep slow breathing [DSB]) modulation of parasympathetic tone results in pain attenuation and enhanced gut motility. Thus, the aims were to investigate whether t-VNS and DSB could enhance the parasympathetic tone, decrease pain sensitivity and improve gut motility in CP. Patients and methods A total of 20 patients (12 males, mean age=61 years, range: 50–78 years) with CP were randomized to short-term (60 minutes) t-VNS and DSB, or their placebo equivalent, in a crossover design. Cardiometrically derived parameters of autonomic tone, quantitative sensory testing of bone and muscle pain pressure, conditioned pain modulation (CPM) and assessments of gastroduodenal motility with ultrasound were performed. Results In comparison to sham, t-VNS and DSB increased cardiac vagal tone (CVT) (P<0.001). However, no changes in pain pressure thresholds for bone (P=0.95) or muscle (P=0.45) were seen. There was diminished CPM (P=0.04), and no changes in gastroduodenal motility were observed (P=0.3). Conclusion This explorative study demonstrated that t-VNS and DSB increased CVT in patients with CP. However, this short-lasting increase did not affect pain sensitivity to musculoskeletal pain or gastroduodenal motility. The chronic pain in CP patients is complex, and future trials optimizing neuromodulation for pain relief and improved motility are needed.

Abstract
BACKGROUND The prevalence and impact of chronic gastrointestinal dysmotility following total pancreactectomy with islet autotransplantation (TP-IAT) for chronic pancreatitis is not known. METHODS A cross-sectional study of all patients who underwent TP-IAT at our institution from August 2011 to November 2015 was undertaken. The GCSI (Gastroparesis Cardinal Symptom Index), PAGI-SYM (Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index), PAC-SYM (Patient Assessment of Constipation Symptoms), Bristol stool chart, 12-item Short Form Health Survey (SF-12), and visual analog scale for pain were administered ≥4 weeks following TP-IAT. KEY RESULTS The prevalence of any dysmotility symptoms in patients who completed the survey (33/45, 73%) post-TP-IAT was 45%. Post-TP-IAT, the mean reduction in opioid dosing was 77.6 oral morphine equivalents (OMEs) (95% CI 32.1-123.0, p = 0.002) with 42% of patients requiring no opioids. There was significant negative correlation between dysmotility scores and SF-12 physical scores (r = -0.46, p = 0.008, 95% CI -0.70 to -0.13). Self-reported abdominal pain had significant negative correlation with both physical and mental SF-12 scores (r = -0.67, p < 0.001, 95% CI -0.83 to -0.41 and r = -0.39, p = 0.03, 95% CI -0.65 to -0.04). There was no correlation between gastrointestinal dysmotility and self-reported pain. CONCLUSIONS AND INFERENCES Symptoms of chronic gastrointestinal dysmotility and chronic abdominal pain are common post-TP-IAT and will need to be better recognized and differentiated to improve the management of these patients.

Abstract
Background. Treatment of intractable pain due to chemotherapy induced peripheral neuropathy (CIPN) is a challenge. Intravenous (iv) lidocaine has shown to be a treatment option for neuropathic pain of different etiologies. Methods. Lidocaine (1.5 mg/kg in 10 minutes followed by 1.5 mg/kg/h over 5 hours) was administered in nine patients with CIPN, and analgesic effect was evaluated during infusion and after discharge. The immediate effect of lidocaine on pressure pain thresholds (PPT) and the extent of the stocking and glove distribution of sensory abnormalities (cold and pinprick) were assessed. Results. Lidocaine had a significant direct analgesic effect in 8 out of 9 patients (P = 0.01) with a pain intensity difference of >30%. Pain reduction persisted in 5 patients for an average of 23 days. Lidocaine did not influence mean PPT, but there was a tendency that the extent of sensory abnormalities decreased after lidocaine. Conclusion. Iv lidocaine has direct analgesic effect in CIPN with a moderate long-term effect and seems to influence the area of cold and pinprick perception. Additional research is needed, using a control group and larger sample sizes to confirm these results.

Abstract
There is tremendous interpatient variability in the response to analgesic therapy (even for efficacious treatments), which can be the source of great frustration in clinical practice. This has led to calls for "precision medicine" or personalized pain therapeutics (ie, empirically based algorithms that determine the optimal treatments, or treatment combinations, for individual patients) that would presumably improve both the clinical care of patients with pain and the success rates for putative analgesic drugs in phase 2 and 3 clinical trials. However, before implementing this approach, the characteristics of individual patients or subgroups of patients that increase or decrease the response to a specific treatment need to be identified. The challenge is to identify the measurable phenotypic characteristics of patients that are most predictive of individual variation in analgesic treatment outcomes, and the measurement tools that are best suited to evaluate these characteristics. In this article, we present evidence on the most promising of these phenotypic characteristics for use in future research, including psychosocial factors, symptom characteristics, sleep patterns, responses to noxious stimulation, endogenous pain-modulatory processes, and response to pharmacologic challenge. We provide evidence-based recommendations for core phenotyping domains and recommend measures of each domain.

Abstract
Objectives Chronic gneck and shoulder pain (CNSP) is a common clinical symptom of cervical spondylotic radiculopathy. Several studies using resting-state functional magnetic resonance imaging (rs-fMRI) have reported that most chronic pain diseases are accompanied by structural and functional changes in the brain. However, few rs-fMRI studies have examined CNSP. The current study investigated cerebral structural and functional changes in CNSP patients. Methods In total, 25 CNSP patients and 20 healthy volunteers participated in the study. 3D-T1W and rs-fMRI images were acquired. Voxel-based morphometry analysis was applied to structural images, and regional homogeneity (ReHo) was extracted from rs-fMRI. Statistical analysis was performed on post-processing images and ReHo parameter maps. Results The results revealed no significant differences in brain structure between the two groups. In the patient group, ReHo values were significantly increased in the bilateral middle frontal gyrus and decreased in the left insula, superior frontal gyrus, middle cingulate gyrus, supplementary motor area, right postcentral gyrus, and superior parietal lobule. Conclusions This initial structural and rs-fMRI study of CNSP revealed characteristic features of spontaneous brain activity of CNSP patients. These findings may be helpful for increasing our understanding of the neuropathology of CNSP.

Abstract
Chronic pancreatitis (CP) is a progressive inflammatory disease, which leads to loss of pancreatic function and other disease-related morbidities. A group of academic physicians and scientists developed comprehensive guidance statements regarding the management of CP that include its epidemiology, diagnosis, medical treatment, surgical treatment, and screening. The statements were developed through literature review, deliberation, and consensus opinion. These statements were ultimately used to develop a conceptual framework for the multidisciplinary management of chronic pancreatitis referred to as an academic pancreas center of excellence (APCOE).

Total Pancreatectomy With Islet Autotransplantation Improves Quality of Life in Patients With Refractory Recurrent Acute Pancreatitis. Clin Gastroenterol Hepatol 2016; 14:1317-23. [PMID: 26965843 PMCID: PMC5538725 DOI: 10.1016/j.cgh.2016.02.027] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2015] [Revised: 02/21/2016] [Accepted: 02/22/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Therapeutic options are limited for patients with recurrent acute pancreatitis who have intractable symptoms despite maximal endoscopic and medical treatment, but equivocal or no morphologic or functional evidence of chronic pancreatitis. We performed a prospective observational cohort study to determine the efficacy of total pancreatectomy with islet autotransplantation (TPIAT) for these patients. METHODS We collected data from all patients undergoing TPIAT at the University of Minnesota from 2007 through 2013; 49 patients (42 female; mean age, 32.8 ± 7.8 years) had a diagnosis of recurrent acute pancreatitis not provoked by intervention, with negative or equivocal findings from nondiagnostic imaging or pancreatic function tests for chronic pancreatitis, and intractable pain between episodes. Data on insulin use, narcotic requirements, pain scores, and health-related quality of life were collected before TPIAT; 3 months, 6 months, and 1 year afterward; and then yearly. RESULTS All 49 patients studied required narcotics before TPIAT (45 daily users and 4 intermittent users); 2 had insulin-treated diabetes. At 1 year after TPIAT, 22 out of 48 patients (46%) reported no use of narcotic pain medications (P < .001 vs baseline). Health-related quality of life score, measured by the physical and mental component summary score, increased by approximately 1 standard deviation from the population mean (P < .001 for the physical component summary; P = .019 for the mental component summary). At 1 year after TPIAT, 21 out of 48 patients (45%) were insulin independent; their mean percent glycosylated hemoglobin A1c at 1 year after TPIAT was 6.0% ± 0.9% (5.2% ± 0.6% pre-TPIAT). CONCLUSIONS Patients with recurrent acute pancreatitis but lacking clear chronic pancreatitis benefit from TPIAT, with outcomes similar to those previously described for patients with chronic pancreatitis (improved quality of life and reduced narcotic use). For these patients who have otherwise limited surgical treatment options, TPIAT can be considered when medical and endoscopic therapies have failed.

Abstract
PURPOSE OF REVIEW To summarize observations in clinical chronic pancreatitis in the past year. RECENT FINDINGS A predisposing genetic mutation was identified in 67% of cases of pediatric chronic pancreatitis. A novel susceptibility gene involving a hybrid allele is associated with idiopathic chronic pancreatitis. ABO blood type B and FUT2 nonsecretor status is associated with asymptomatic hyperlipasemia and chronic pancreatitis. Alcohol consumption impairs cystic fibrosis transmembrane conductance regulator (CFTR) activity leading to decreased bicarbonate secretion and patients with susceptible CFTR mutations can develop clinical pancreatitis. Computed tomography imaging findings in chronic pancreatitis correlate poorly with pain patterns. Endoscopic ultrasound features correlate poorly with fibrosis. Circulating epithelial cells are present in chronic pancreatitis patients but not healthy volunteers. Surgery is superior to endoscopic treatment in providing durable pain relief (>5 years). Repetitive pancreatic duct stent placements and chronic narcotic use are preoperative predictors of poor outcome after total pancreatectomy with islet cell auto transplantation. SUMMARY Novel genetic mutations for idiopathic chronic pancreatitis are being identified. Alcohol impairs CFTR activity and may explain a mechanism for pancreatitis. Current imaging modalities correlate poorly with clinical pain presentation and fibrosis in chronic pancreatitis. Novel imaging modalities are needed. As total pancreatectomy with islet cell auto transplantation grows, rigorous outcomes analysis is needed to drive patient selection.

Abstract
Despite marked differences in underlying pathophysiology, the current management of visceral pain largely follows the guidelines derived from the somatic pain literature. The effective management of patients with chronic visceral pain should be multifaceted, including both pharmacological and psychological interventions, thereby providing a mechanism-orientated approach to treatment. Patients can frequently become disenfranchised, and subsequently disengaged, with healthcare providers leading to repeated consultations. Thus, a key aspect of management is to break this cycle by validating patients' symptoms, adopting an empathic approach and taking time to educate patients. To optimize treatment and outcomes in chronic visceral pain we need to move away from approaches exclusively based on dealing with peripheral nociceptive input toward more holistic strategies, taking into account alterations in central pain processing.

Predictors of Post-Operative Pain Relief in Patients with Chronic Pancreatitis Undergoing the Frey or Whipple Procedure. J Gastrointest Surg 2016; 20:734-40.

Abstract
BACKGROUND Post-operative pain relief in chronic pancreatitis (CP) is variable. Our objective was to determine clinical imaging or histopathologic predictor(s) of post-operative pain relief in CP patients undergoing the Whipple or Frey procedure. METHODS All patients who underwent a Whipple (n = 30) or Frey procedure (n = 30) for painful CP between January 2003 and September 2013 were evaluated. A toxic etiology was defined as a history of alcohol use and/or smoking. The pre-operative abdominal CT was evaluated for calcification(s) and main pancreatic duct (MPD) dilation (≥5 mm). The post-operative histopathology was evaluated for severe fibrosis. Clinical imaging and histopathologic features were evaluated as predictors of post-operative pain relief using univariable and multivariable regression analysis. RESULTS A total of 60 patients (age 51.6 years, 53% males) were included in our study, of whom 42 (70%) reported post-operative pain relief over a mean follow-up of 1.1 years. There were 37 (62%) patients with toxic etiology, 36 (60%) each with calcification(s) and MPD dilation. A toxic etiology, calcifications, and severe fibrosis were associated with post-operative pain relief on univariable analysis (all p < 0.01). However, only a toxic etiology was an independent predictor of post-operative pain relief (OR 5.7, 95% CI 1.3, 24.5, p = 0.02). CONCLUSION Only a toxic etiology, and not imaging or histopathologic findings, independently predicts post-operative pain relief in CP patients undergoing the Whipple or Frey procedure.

Abstract
Chronic pain has multiple mechanisms that result in pain amplification and maintenance, including central and peripheral sensitization and altered modulation of pain perception. Assessment of pain requires comprehensive assessment of symptoms and signs, suspected pain mechanisms, and the patient's biopsychosocial context. Multiple validated measures exist for the assessment of pain symptoms, pain-related disability, psychological impact of pain, and candidacy for opioid management.

Abstract
DESCRIPTION Pain in patients with chronic pancreatitis (CP) remains the primary clinical complaint and source of poor quality of life. However, clear guidance on evaluation and treatment is lacking. METHODS Pancreatic Pain working groups reviewed information on pain mechanisms, clinical pain assessment and pain treatment in CP. Levels of evidence were assigned using the Oxford system, and consensus was based on GRADE. A consensus meeting was held during PancreasFest 2012 with substantial post-meeting discussion, debate, and manuscript refinement. RESULTS Twelve discussion questions and proposed guidance statements were presented. Conference participates concluded: Disease Mechanism: Pain etiology is multifactorial, but data are lacking to effectively link symptoms with pathologic feature and molecular subtypes. Assessment of Pain: Pain should be assessed at each clinical visit, but evidence to support an optimal approach to assessing pain character, frequency and severity is lacking. MANAGEMENT There was general agreement on the roles for endoscopic and surgical therapies, but less agreement on optimal patient selection for medical, psychological, endoscopic, surgical and other therapies. CONCLUSIONS Progress is occurring in pain biology and treatment options, but pain in patients with CP remains a major problem that is inadequately understood, measured and managed. The growing body of information needs to be translated into more effective clinical care.

Abstract
Chronic pancreatitis (CP) is a chronic inflammatory disease of the pancreas. The main symptom of patients with CP is chronic and severe abdominal pain. However, the pathophysiology of pain in CP remains obscure. Traditionally, researchers believed that the pain was caused by anatomical changes in pancreatic structure. However, treatment outcomes based on such beliefs are considered unsatisfactory. The emerging explanations of pain in CP are trending toward neurobiological theories. This article aims to review current evidence regarding the neuropathophysiology of pain in CP and its potential implications for the development of new treatments for pain in CP.

Abstract
PURPOSE OF REVIEW Pain is the most common symptom of chronic pancreatitis, with a profound socioeconomic impact. Historical management paradigms failed, as they did not adequately address the fundamental underlying mechanisms. The present article describes the neurobiology of pain and sensitization in this condition, in an effort to explain prior failings and provide future directions for managing pain in chronic pancreatitis. RECENT FINDINGS A number of recent advances have been made in understanding the neurobiology of pain for this condition. This has been coupled with clinical advances in assessing sensitization to pain in these patients, which has been shown to predict response to medical and surgical therapy. SUMMARY Pain in chronic pancreatitis is complex. Addressing the mechanical and morphological findings in chronic pancreatitis without addressing the underlying neurobiological mechanisms is destined to fail. New advances in our understanding of the neurobiology of pain in chronic pancreatitis helps to explain prior failings and provides future direction for managing pain in patients afflicted by this disease.
