Soft self-expandable metal stent to treat painful pancreatic duct strictures secondary to chronic pancreatitis: a prospective multicenter trial. Gastrointest Endosc 2023; 97:472-481.e3.

Abstract
BACKGROUND AND AIMS Fully covered self-expandable metal stents (FCSEMSs) may offer a treatment option for pain associated with a dilated pancreatic duct (PD) in chronic pancreatitis (CP), but optimal patient selection and FCSEMS design, efficacy, and safety remain uncertain. We studied an investigational pancreatic FCSEMS for treatment of CP-associated pain. METHODS Patients with painful CP, a dominant distal PD stricture, and PD dilation upstream were enrolled in a prospective, multicenter, single-arm trial studying 6-month indwell of a 4- to 6-cm-long soft pancreatic FCSEMS. Primary efficacy and safety endpoints were pain reduction 6 months after FCSEMS indwell (performance goal ≥53%) and PD stenting-related serious adverse events (SAEs), respectively (performance goal <32%). The primary efficacy endpoint was assessed in patients with sufficiently severe and frequent pain at FCSEMS placement as a first stent or in exchange of a plastic stent. RESULTS Among 67 patients (mean age, 52.7 ± 12.5 years; mean time since CP diagnosis, 6.4 ± 6.4 years), 34 (50.7%) had plastic stent placement within 90 days of FCSEMS placement, and 46 patients were eligible for the primary efficacy endpoint analysis. Technical success was 97.0% (65/67). The observed primary efficacy (26.1%, 12/46) and safety endpoints (31.3%, 21/67) failed to meet the a priori study hypotheses. Study stent migration occurred in 47.7% of patients (31/65). CONCLUSIONS Six-month treatment with an FCSEMS did not lead to an expected degree of pain reduction, and migrations and SAEs were common. Further study is needed to clarify optimal decompressive strategy, FCSEMS design, and patient selection. (Clinical trial registration number: NCT02802020.).

Abstract
BACKGROUND/OBJECTIVES Data regarding incidence, health-care burden, and predictors for readmission in patients with acute alcoholic pancreatitis (AAP) is scarce. We aim to identify incidence, health-care burden, and predictors of readmission over an 11-month period. METHODS Retrospective cohort study using the 2016 National Readmission Database of adult patients admitted with a principal diagnosis of AAP in January and 11-month readmission follow up for all-cause readmission. Incidence of all-cause readmission, mortality rate, morbidity, length of stay (LOS), total hospitalization charges and costs were evaluated. Independent risk factors for all-cause readmission were identified using a Cox multivariate logistic regression analysis. RESULTS A total of 6633 patients were included in the study. The mean age was 45.7 years and 28.9% of patients were female. 73.1% of patients had a modified BISAP score of 0. The 11-month readmission rate was 43.1%. The main cause of readmission was another episode of AAP. The mortality rate of readmission was 0.5% and the mortality rate during the index admission (IA) was 1.1% (P = 0.03). The mean LOS, total hospitalization charges and costs for readmission were 4.5 days, $34,307 and $8958, respectively. Independent predictors of readmission were Charlson Comorbidity Index score of ≥ 3, associated chronic alcoholic pancreatitis, and chronic pancreatitis (CP) from other causes. CONCLUSION Among patients admitted with AAP, the 11-month readmission rate was 43.1%. Over one-third of readmissions were due to another episode of AAP. Readmission associated with significant resource utilization. Special attention should be placed in patients with underlying CP due to the increased risk of readmission.

A Macrophage Membrane-Polymer Hybrid Biomimetic Nanoplatform for Therapeutic Delivery of Somatostatin Peptide to Chronic Pancreatitis. Pharmaceutics 2022; 14:pharmaceutics14112341. [PMID: 36365160 PMCID: PMC9698601 DOI: 10.3390/pharmaceutics14112341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 10/23/2022] [Accepted: 10/26/2022] [Indexed: 11/16/2022] Open
Abstract
The clinical translation of therapeutic peptides is generally challenged by multiple issues involving absorption, distribution, metabolism and excretion. In this study, a macrophage membrane-coated poly(lactic-co-glycolic acid) (PLGA) nanodelivery system was developed to enhance the bioavailability of the somatostatin (SST) peptide, which faces the hurdles of short half-life and potential side effects in the treatment of chronic pancreatitis. Using a facile nanoprecipitation strategy, SST was loaded in the nanoparticles with an encapsulation efficiency (EE) and a loading efficiency (LE) of 73.68 ± 3.56% and 1.47 ± 0.07%, respectively. The final formulation of SST-loaded nanoparticles with the camouflage of macrophage membrane (MP-SST) showed a mean diameter of 151 ± 4 nm and an average zeta potential of −29.6 ± 0.3 mV, which were stable long term during storage. With an above 90% cell viability, a hemolysis level of about 2% (<5%) and a preference for being ingested by activated endothelial cells compared to macrophages, the membrane−polymer hybrid nanoparticle showed biocompatibility and targeting capability in vitro. After being intravenously administered to mice with chronic pancreatitis, the MP-SST increased the content of SST in the serum (123.6 ± 13.6 pg/mL) and pancreas (1144.9 ± 206.2 pg/g) compared to the treatment of (Dulbecco’s phosphate-buffered saline) DPBS (61.7 ± 6.0 pg/mL in serum and 740.2 ± 172.4 pg/g in the pancreas). The recovery of SST by MP-SST downregulated the expressions of chronic pancreatitis-related factors and alleviated the histologic severity of the pancreas to the greatest extent compared to other treatment groups. This augmentation of SST therapeutic effects demonstrated the superiority of integrating the synthetic polymer with biological membranes in the design of nanoplatforms for advanced and smart peptide delivery. Other peptides like SST can also be delivered via the membrane−polymer hybrid nanosystem for the treatment of diseases, broadening and promoting the potential clinical applications of peptides as therapeutics.

Abstract
Though liver is the most commonly affected organ in patients with chronic and excessive intake of alcohol, no organ is immune to toxic effects of alcohol and patients with alcohol-related liver disease (ALD) can suffer from a wide list of extrahepatic manifestations involving gastrointestinal tract, central and peripheral nervous systems, cardio vascular system, musculo-skeletal system, disruption of nutritional status, endocrinological abnormalities, hematological abnormalities and immune dysfunction. These extrahepatic organ involvements are usually overlooked by hepatologists and physicians who are mostly focused on managing life threatening complications of ALD. As a result, there is delayed diagnosis, delay in the initiation of appropriate treatment and late referral to other specialists. Some of these manifestations are of utmost clinical importance (e.g. delirium tremans and Wernicke's encephalopathy) because an early diagnosis and treatment can lead to full recovery while delayed or no treatment can result in death. On the other hand, several extrahepatic manifestations are of prognostic significance (such as alcoholic cardiomyopathy and malignancies) in which there is an increased risk of morbidity and mortality. Hence, a clear understanding and awareness of the extrahepatic manifestations of ALD is quintessential for proper management of these patients.

Abstract
BACKGROUND/OBJECTIVES Alcoholic acute pancreatitis (AAP) comprises the second most common cause of acute pancreatitis in the USA, and there is lack of data regarding 30-day specific readmission causes and predictors. We aim to identify 30-day readmission rate, causes, and predictors of readmission. METHODS Retrospective analysis of the 2016 National Readmission Database of adult patients readmitted within 30 days after an index admission for AAP. RESULTS Totally, 76,609 AAP patients were discharged from the hospital in 2016. The 30-day readmission rate was 12%. The main cause of readmission was another episode of AAP. Readmission was not associated with higher mortality (1.3% vs. 1.2%; P = 0.21) or prolonged length of stay (5.2 vs. 5.0 days; P = 0.06). The total health care economic burden was $354 million in charges and $90 million in costs. Independent predictors of readmission were having Medicaid insurance, a Charlson comorbidity index score ≥ 3, use of total parenteral nutrition, opioid abuse disorder, prior pancreatic cyst, chronic alcoholic pancreatitis, and other chronic pancreatitis. Obesity was associated with lower odds of readmission. CONCLUSION Readmission rate for AAP is high and its primary cause are recurrent episodes of AAP. Alcohol and substance abuse pose a high burden on our health care system. Public health strategies should be targeted to provide alcohol abuse disorder rehabilitation and cessation resources to alleviate the burden on readmission, the health care system and to improve patient outcomes.

Abstract
BACKGROUND & AIMS Benign biliary strictures (BBS) are complications of chronic pancreatitis (CP). Endotherapy using multiple plastic stents (MPS) or a fully covered self-expanding metal stent (FCSEMS) are acceptable treatment options for biliary obstructive symptoms in these patients. METHODS Patients with symptomatic CP-associated BBS enrolled in a multicenter randomized noninferiority trial comparing 12-month treatment with MPS vs FCSEMS. Primary outcome was stricture resolution status at 24 months, defined as absence of restenting and 24-month serum alkaline phosphatase not exceeding twice the level at stenting completion. Secondary outcomes included crossover rate, numbers of endoscopic retrograde cholangiopancreatography (ERCPs) and stents, and stent- or procedure-related serious adverse events. RESULTS Eighty-four patients were randomized to MPS and 80 to FCSEMS. Baseline technical success was 97.6% for MPS and 98.6% for FCSEMS. Eleven patients crossed over from MPS to FCSEMS, and 10 from FCSEMS to MPS. For MPS vs FCSEMS, respectively, stricture resolution status at 24 months was 77.1% (54/70) vs 75.8% (47/62) (P = .008 for noninferiority intention-to-treat analysis), mean number of ERCPs was 3.9 ± 1.3 vs 2.6 ± 1.3 (P < .001, intention-to-treat), and mean number of stents placed was 7.0 ± 4.4 vs 1.3 ± .6 (P < .001, as-treated). Serious adverse events occurred in 16 (19.0%) MPS and 19 (23.8%) FCSEMS patients (P = .568), including cholangitis/fever/jaundice (9 vs 7 patients respectively), abdominal pain (5 vs 5), cholecystitis (1 vs 3) and post-ERCP pancreatitis (0 vs 2). No stent- or procedure-related deaths occurred. CONCLUSIONS Endotherapy of CP-associated BBS has similar efficacy and safety for 12-month treatment using MPS compared with a single FCSEMS, with FCSEMS requiring fewer ERCPs over 2 years.

Abstract
Alcoholic beverages stimulate pancreatic enzyme secretions by inducing cholecystokinin (CCK) release. CCK is the major stimulatory hormone of pancreatic exocrine secretions, secreted from enteroendocrine I-cells of the intestine. Fermentation products of alcoholic beverages, such as maleic and succinic acids, influence gastric acid secretions. We hypothesize that maleic and succinic acids stimulate pancreatic exocrine secretions during beer and wine ingestion by increasing CCK secretions. Therefore, the effects of maleic and succinic acids on CCK release were studied in duodenal mucosal cells and the enteroendocrine cell line STC-1. Mucosal cells were perfused for 30 min with 5 min sampling intervals, STC-1 cells were studied under static incubation for 15 min, and supernatants were collected for CCK measurements. Succinate and maleate-induced CCK release were investigated. Succinate and maleate doses dependently stimulated CCK secretions from mucosal cells and STC-1 cells. Diltiazem, a calcium channel blocker, significantly inhibited succinate and maleate-induced CCK secretions from mucosal cells and STC-1 cells. Maleate and succinate did not show cytotoxicity in STC-1 cells. Our results indicate that succinate and maleate are novel CCK-releasing factors in fermented alcoholic beverages and could contribute to pancreatic exocrine secretions and their pathophysiology.

Characterization of KRAS Mutation in Acinar and Langerhans Islet Cells of Patients With Pancreatic Ductal Adenocarcinoma. Pancreas 2016; 45:337-41.

Abstract
OBJECTIVES KRAS mutations are frequent in pancreatic ductal adenocarcinoma, chronic pancreatitis, and mucinous neoplasms. In animal studies, KRAS mutations in acinar and Langerhans islets are associated with pancreatic intraepithelial neoplasia. Clinically, KRAS mutation is sometimes requested on cytology/biopsy specimens and negative results are helpful to rule out pancreatic ductal adenocarcinoma. This study set out to further elucidate these issues. METHODS Surgical specimens with pancreatic ductal adenocarcinoma, premalignant lesions, and chronic pancreatitis were reviewed. Tissue microdissections on 53 such areas of 21 cases were performed followed by polymerase chain reaction and pyrosequencing. RESULTS KRAS codon 12 mutations were detected in 100% pancreatic ductal adenocarcinomas. No KRAS codon 12 and 13 mutations were detected in benign acinar and Langerhans islets that lie adjacent to or away from the tumor. Variable mutation frequencies were seen in premalignant lesions. CONCLUSIONS The results support such clinical practice that negative KRAS mutation helps rule out pancreatic ductal adenocarcinomas on small cytology/biopsy specimens. Negative KRAS mutations, however, cannot rule out pancreatic premalignant lesions. Additionally, the results that benign pancreas are negative for KRAS mutations complement the findings of other relevant study that KRAS mutation-associated premalignant lesions do not appear to arise from acinar cells or Langerhans islets.

Abstract
OBJECTIVE The aim of this study was to report on 15-year long-term results of a randomized controlled trial comparing extended drainage procedure (Frey) and classical resectional procedure [pylorus-preserving pancreatoduodenectomy (PD)] in patients with chronic pancreatitis. BACKGROUND Chronic pancreatitis is a common inflammatory disease with a prevalence of 10 to 30 cases per 100,000 inhabitants. It is characterized by the progressive conversion of pancreatic parenchyma to fibrous tissue. Different surgical procedures are used in treatment of persistent pain. METHODS Sixty-four patients suffering from chronic pancreatitis with inflammatory mass in the pancreatic head were randomly assigned in 2 treatment groups (PD, n = 32) and (Frey, n = 32). The perioperative course of the randomized controlled trial and the 7 years follow-up have been previously published. All participating patients were contacted with a standardized, validated questionnaire (EORTC QLQ C30) to evaluate the long-term survival, quality-of-life pain, and exocrine and endocrine function. RESULTS In the 15-year long-term follow-up, the pain control was good and comparable between both groups, but the quality of life was better after Frey procedure in regard of the physical status [PD: 100 (0-100) vs PD: 60 (0-100) (P = 0.011)]. No significant differences in terms of the Pain Score were detected between both groups [PD: 7 (0-100) vs Frey 4 (0-100) P = 0.258]. Seven patients after Frey OP and 6 patients after PD were free of pain. Analyzing the postoperative overall survival, a higher long-term mortality was found after PD (53%) than that found after Frey procedure (30%) resulting in a longer mean survival (14.5 ± 0.8 vs 11.3 ± 0.8 years; P = 0.037). No correlation between endocrine or exocrine pancreatic function and pain was found, whereas continuous alcohol consumption was associated with poorer outcome regarding quality of life (P < 0.001) and pain score (P < 0.001). CONCLUSIONS PD and Frey procedure provide good and permanent pain relief and improvement of the quality of life in long-term follow-up. In addition, a longer survival was found after the organ sparing resection. Together with better short-term results, the organ-sparing procedure seems to be favorable in treatment of chronic pancreatitis.

Abstract
INTRODUCTION The management of pain in chronic benign pancreatitis is complex. Celiac plexus neurolysis provides pain relief of variable duration. Neuromodulation of splanchnic nerves with electrodes and an implantable pulse generator system is an alternative to producing long-term pain relief with minimal complications in selected cases. METHODS A 36-year-old lady with intractable abdominal pain for five years from chronic benign pancreatitis presented to our pain clinic. Multiple pharmacotherapy regimens, surgery, and interventions produced temporary pain relief of variable duration and intensity. Following a successful trial of celiac plexus stimulation, neuromodulation of the splanchnic nerves was achieved with two permanently implanted octopolar leads at the T11/T12 area connected to an implantable pulse generator. RESULTS Eighteen months following the implant, the patient continues to derive satisfactory pain relief without any device related complications. Her opiate use is significantly reduced from 225 (486 mg morphine per day) to 12.5 (27 mg morphine per day) micrograms/h fentanyl patches and the fentanyl lozenges were stopped with an increase in appetite and of more than 8 kg in weight gain. The initial pain score visual analogue scale (VAS) 8-9/10 was reduced to VAS 0/10 since implantation. DISCUSSION The pain of chronic pancreatitis has both visceral and somatic components as evidenced by the lack of complete pain relief from celiac plexus block alone and the knowledge that in chronic disease, the pathology extends to extra pancreatic somatic tissues, particularly the retro-peritoneum. We postulate that the electrical field generated by the dual octrode system extends to include splanchnic nerves and other somatic innervation of the pancreas. CONCLUSION In our opinion, this is the first case of a successful long-term neuromodulation of splanchnic nerves with a permanently implanted device. The potential exists for its use in visceral abdominal pain of varied etiology, once more experience is obtained with this technique.

Abstract
Alcohol abuse is one of the most common causes of pancreatitis. The risk of developing alcohol-induced pancreatitis is related to the amount and duration of drinking. However, only a small portion of heavy drinkers develop disease, indicating that other factors (genetic, environmental, or dietary) contribute to disease initiation. Epidemiologic studies suggest roles for cigarette smoking and dietary factors in the development of alcoholic pancreatitis. The mechanisms underlying alcoholic pancreatitis are starting to be understood. Studies from animal models reveal that alcohol sensitizes the pancreas to key pathobiologic processes that are involved in pancreatitis. Current studies are focussed on the mechanisms responsible for the sensitizing effect of alcohol; recent findings reveal disordering of key cellular organelles including endoplasmic reticulum, mitochondria, and lysosomes. As our understanding of alcohol's effects continue to advance to the level of molecular mechanisms, insights into potential therapeutic strategies will emerge providing opportunities for clinical benefit.

Abstract
INTRODUCTION Chronic pancreatitis (CP) is a disease with enormous social and personal impact. It is most commonly caused by the abuse of alcohol combined with nicotine. CP is usually characterised by an inflammatory mass located in the pancreatic head. Its natural course is characterised by persistent or recurrent painful attacks as well as progressive loss of pancreatic function due to fibrosis of the parenchyma with consecutive endocrine and exocrine insufficiency. CONCLUSIONS The only success parameter of any treatment is the effective long-lasting pain relief and improvement in the quality of life. The surgical armamentarium includes simple drainage procedures, resections of different extents or a combination of both. Duodenum-preserving resection of the pancreas offers the best short-term outcome according to trials conducted so far. It has the benefit of combining the highest safety with the highest efficiency. Additionally, the extent of the operation can be adapted to the morphology of the individual patient.

Abstract
OBJECTIVES Low-dose ionizing radiation from medical imaging has been indirectly linked with subsequent cancer. Computed tomography (CT) is the gold standard for defining pancreatic necrosis. The primary goal was to identify the frequency and effective radiation dose of CT imaging for patients with necrotizing pancreatitis. METHODS All patients with necrotizing pancreatitis (2003-2007) were retrospectively analyzed for CT-related radiation exposure. RESULTS Necrosis was identified in 18% (238/1290) of patients with acute pancreatitis (mean age = 53 years; hospital/ICU length of stay = 23/7 days; mortality = 9%). A median of five CTs/patient [interquartile range (IQR) = 4] were performed during a median 2.6-month interval. The average effective dose was 40 mSv per patient (equivalent to 2,000 chest X-rays; 13.2 years of background radiation; one out of 250 increased risk of fatal cancer). The actual effective dose was 63 mSv considering various scanner technologies. CTs were infrequently (20%) followed by direct intervention (199 interventional radiology, 118 operative, 12 endoscopic) (median = 1; IQR = 2). Magnetic resonance imaging did not have a CT-sparing effect. Mean direct hospital costs increased linearly with CT number (R = 0.7). CONCLUSIONS The effective radiation dose received by patients with necrotizing pancreatitis is significant. Management changes infrequently follow CT imaging. The ubiquitous use of CT in necrotizing pancreatitis raises substantial public health concerns and mandates a careful reassessment of its utility.

Abstract
Over the past decades several epidemiological studies have been published reporting on incidence trends, hospital admissions, etiological factors and outcome of both acute and chronic pancreatitis. Over time, the incidence of acute pancreatitis has increased in the Western countries. Also, the number of hospital admissions for both acute and chronic pancreatitis have increased. These upward time trends possibly reflect a change in the prevalence of main etiological factors (e.g. gallstones and alcohol consumption) and cofactors such as obesity and genetic susceptibility. Acute and chronic pancreatitis are associated with significant morbidity and mortality and a substantial use of health care resources. Although the case-fatality rate of acute pancreatitis decreased over time, the overall population mortality did not change for both acute and chronic pancreatitis. This chapter will focus on recent developments in the epidemiology, aetiology, natural course and outcome of both acute and chronic pancreatitis.

Abstract
INTRODUCTION The prognosis of patients with acute pancreatitis is still uncertain regardless of modern therapeutic procedures. It is even more emphasized if the acute pancreatitis is followed by psychic disorders. OBJECTIVE The aim of the study was to provide an overview of the incidence of certain psychosomatic disorders in patients with acute pancreatitis and evaluate priority therapeutic procedures. METHOD In this study, we analysed 16 patients with psychosomatic disorders followed by the episode of acute pancreatitis among 202 patients that were hospitalized in the period from 1993 until 2000. The diagnosis was based on anamnesis, clinical and laboratory findings and diagnostic procedures such as X-ray, US, CT and MRI. RESULTS Among 16 patients with psychosomatic disorders followed by acute pancreatitis, 13 (81.25%) patients were operated on and 3 (18.75%) patients were medically treated. 6 patients experienced hallucinations, 5 memory deficiency, 16 disorientation and 14 confabulation. CONCLUSION Psychosomatic disorders in patients with acute pancreatitis require complex medical treatment. Due to the already mentioned complications, the management of these conditions is very difficult and with uncertain results.

Abstract
Pain is a major clinical manifestation of chronic pancreatitis (CP) and a common indication for surgery in these patients. Pathogenesis of pain in CP is multifactorial and the mechanisms of pain may differ from patient to patient. This can explain why one therapeutic method of treatment of pain does not work in all patients and in different stages of the disease. Two main complimentary pathogenetic theories have been proposed to explain the mechanisms of pain in CP, the neurogenic theory and the theory of increased intraductal/intraparenchymal pressures. According to the neurogenic theory, in CP there are alterations of pancreatic/peripancreatic nerves, exposing them to noxious substances and/or activated immune cells, thereby generating pain ("neuroimmune interaction"). The other theory of intraductal/intraparenchymal hypertension suggests that pain in CP is generated as a result of increased pressures within the pancreatic ductal system and/or pancreatic parenchyma, like the pain in the classic compartment syndrome. The theory of intraductal/intraparenchymal hypertension is strongly supported by the good results of drainage procedures in the surgical management of CP. Pancreatic ischemia, oxygen-free radicals, centrally sensitized pain state, acute exacerbations of CP, development of complications from the pancreas (most commonly, pseudocysts) or adjacent organs (usually, duodenal and/or common bile duct stenosis), etc. are other possible contributing factors. Different patterns of pain have been described in idiopathic (early vs. late onset) and in alcoholic CP. Interestingly, pain is automatically relieved during the natural course of the disease in some patients (the "burn-out" phenomenon), after a relatively long time (from a few years to up to 3 decades). However, this is an unpredictable evolution for the individual patient. Therefore, surgery should be offered when pain is intense and after failure of conservative treatment. Surgical management should be individualized, depending on the particular findings of each patient. The knowledge of the pathophysiologic basis and of natural course of pain in CP is of paramount importance for the surgeon to select appropriate therapy for the individual patient with CP.

Abstract
Chronic, debilitating abdominal pain is arguably the most important component of chronic pancreatitis, leading to significant morbidity and disability. Attempting to treat this pain, which is too often unsuccessful, is a frustrating experience for physician and patient. Multiple studies to improve understanding of the pathophysiology that causes pain in some patients but not in others have been performed since the most recent reviews on this topic. In addition, new treatment modalities have been developed and evaluated in this population. This review discusses new advances in neuroscience and the study of visceral pain mechanisms, as well as genetic factors that may play a role. Updates of established therapies, as well as new techniques used in addressing pain from chronic pancreatitis, are reviewed. Lastly, outcome measures, which have been highly variable in this field over the years, are addressed.

Abstract
OBJECTIVE To estimate the incidence of alcoholic pancreatitis, a dependence questionnaire survey was administered to male members of the sobriety association in Japan. METHODS Questionnaires asking about age, age at start of alcohol drinking, amount of alcohol consumption, duration of drinking, the initiated age of abstinence, medical history of pancreatitis, the age at diagnosis of pancreatitis, and the etiology of pancreatitis were sent to 7876 male members of a sobriety association in Japan. RESULTS Of 4120 members who replied to the questionnaire, 857 (20.8%) had a medical history of pancreatitis. Of these 857 members, 418 (10.1%) had been diagnosed with alcoholic pancreatitis, 32 (0.8%) as gallstone pancreatitis, and 407 (9.9%) with unknown etiology or etiology forgotten. A clear history of pancreatitis and information on habitual heavy drinking and the consumed amount of alcohol could be obtained from 373 of the 418 members diagnosed with alcoholic pancreatitis and from 345 of the 407 members with pancreatitis of unknown etiology. These 718 respondents were considered to be true alcoholic pancreatitis cases, with an extrapolated incidence of 9.1% (718/7876) to 17.4% (718/4120) cases of alcoholic pancreatitis in alcoholics in Japan. Alcoholics with a history of pancreatitis began drinking at relatively younger age and consumed a significantly greater amount of alcohol per day compared with 3113 alcoholics without a medical history of pancreatitis. CONCLUSION This survey suggests that the incidence of alcoholic pancreatitis in alcoholics is much higher than previously reported.

Abstract
Alcoholic chronic pancreatitis (CP) is not usually diagnosed until the end stage of the disease, and hence enormous medical and social resources are consumed in the treatment of established alcoholic CP. With the aim of early diagnosis and prevention of alcoholic CP, we here propose "alcoholic pancreatopathy" as a new category of pancreatic disorder induced by alcohol intake. In addition to a history of excessive alcohol intake (>80 g/day), the presence of at least one of the following conditions establishes the diagnosis of alcoholic pancreatopathy: 1. History of alcoholic acute pancreatitis. 2. Recurrent abdominal pain or gastrointestinal symptoms induced by alcohol intake. 3. Hyperamylasemia or a high serum level of any other pancreatic enzymes. 4. Abnormal findings in the pancreas by routine abdominal ultrasonography. Alcoholic pancreatopathy is a comprehensive concept that includes the early stage of pancreatic injury induced by alcohol, and is useful for detecting the preclinical stage of pancreatic injury induced by alcohol and hence for treating the early stage of the disease. Further assessments and well-designed studies for investigating the early stage of alcoholic CP are necessary, in which alcoholic pancreatopathy could play a key role.

Abstract
AIM: To compare the effects of neurolytic celiac plexus block (NCPB) and videothoracoscopic splanchnicectomy (VSPL) on pain and quality of life of chronic pancreatitis (CP) patients.
METHODS: Forty-eight small duct CP patients were treated invasively with NCPB (n = 30) or VSPL (n = 18) in two non-randomized, prospective, case-controlled protocols due to chronic pain syndrome, and compared to a control group who were treated conservatively (n = 32). Visual analog scales were used to assess pain and opioid consumption rate was evaluated. In addition, the quality of life was measured using QLQ C-30 for NCPB and FACIT for VSPL. Although both questionnaires covered similar problems, they could not be compared directly one with another. Therefore, the studies were compared by meta-analysis methodology.
RESULTS: Both procedures resulted in a significant positive effect on pain of CP patients. Opioids were withdrawn totally in 47.0% of NCPB and 36.4% of VSPL patients, and reduced in 53.0% and 45.4% of the respective patient groups. No reduction in opioid usage was observed in the control group. In addition, fatigue and emotional well-being showed improvements. Finally, NCPB demonstrated stronger positive effects on social support, which might possibly be attributed to earlier presentation of patients treated with NCPB.
CONCLUSION: Both invasive pain treatment methods are effective in CP patients with chronic pain.

Abstract
Alcoholic chronic pancreatitis is a severe, disabling, chronic inflammatory condition of the pancreas that is seen in fewer than 5% of alcoholics. The severity and unpredictability of this condition has lead to several theories on the mechanism causing chronic pancreatitis based on careful clinical observation. Hypothetical mechanisms were applied to various animal models. Finally, following multiple lines of evidence, there is a convergence of thought and development of some new models that are quite instructive. Taken together, chronic alcohol consumption by rats results in multiple effects on the pancreas that increase the risk of acute pancreatitis, including ongoing acinar cell injury that lowers the threshold for hyperstimulation-induced acute pancreatitis, neurohormonal injury, and adaptation that results in acinar cell hyperstimulation, increased susceptibility to viral mediated acute pancreatitis, and possibly other factors. After acute pancreatitis initiates the inflammatory process, the chronic inflammation and fibrosis of alcoholic chronic pancreatitis are driven by diet, the acinar cell stress response to continued alcohol that may be potentiated by toxic alcohol metabolites, hypoxia, hyperstimulation, and partial duct obstruction; plus the effects of proinflammatory immunocytes and cytokines; and by stellate cell-mediated fibrosis driven by anti-inflammatory cytokines, alcohol, and alcohol metabolites. The factors determining which alcoholic will develop alcoholic chronic pancreatitis likely involve genetic factors, dietary factors, and susceptibility to pancreatic injury through several mechanisms ranging from trauma to gallstones to viruses.

Abstract
Although the association between alcohol and pancreatitis has been recognized for centuries, the precise magnitude of the impact of alcohol remains poorly quantified. Epidemiologic research on this condition has been seriously handicapped by several factors. Classifications are based on morphology rather than on etiology; the diagnostic differences between acute and chronic pancreatitis are imprecise and confusing; and coding by the International Classification of Diseases (ICD) has been inadequate. The current ICD (ICD-10), used in the United States since 1999, identifies alcohol-induced chronic pancreatitis as a separate code for the first time, an enhancement that will greatly improve the quality of data collected in current and future studies. Unfortunately, no code yet exists for acute alcoholic pancreatitis. Of the approximately 2.4 million deaths in the United States in 1999, pancreatitis was listed as the underlying cause for 3289 deaths, making it the 235th leading cause of death. Acute pancreatitis accounted for 84% of these deaths, and chronic pancreatitis the remaining 16%. Alcohol is a primary cause of both acute and chronic pancreatitis in most developed countries. About one-third of acute pancreatitis in the United States is alcohol-induced. In the United States and other developed countries, 60%-90% of chronic pancreatitis is alcohol induced. Both forms are more common in men. The development of chronic pancreatitis is proportional to the dose and duration of alcohol consumption (minimum, 6-12 years of approximately 80 g of alcohol per day). Autopsy studies reveal subclinical chronic pancreatitis in another 10% of alcohol abusers. Yet, since <10% of chronic alcoholics develop chronic pancreatitis, clearly other predisposing factors besides alcohol are involved. Genetic variability and environmental exposures, such as diet, are prime candidates for further investigation. To date, there have been few large epidemiological studies of alcoholic pancreatitis in the United States or other developed countries. Additional studies are needed to improve the quality of existing baseline epidemiologic data and allow better assessment of risk. Improved diagnostic precision, more complete and specific coding, and greater understanding of covariables and mechanisms would also advance the field.
