Abstract
BACKGROUND Debate exists regarding the optimal treatment for painful chronic pancreatitis (CP). This meta-analysis aims to determine the outcomes of surgical intervention as compared to endoscopy in patients with painful CP. METHODS A systematic review and meta-analysis including studies from PubMed, Embase, Web of Science, and Cochrane Databases (1995 onwards) was done by two independent reviewers using PRISMA guidelines. Primary outcome was pain relief. RESULTS Among 8,479 studies, three were randomized trials, comprising a total of 199 patients. Compared with endoscopy, surgery was associated with a lower Izbicki score, both at medium term (mean difference (MD) 21.46, 95% confidence interval (CI) 13.48-29.43, p < 0.00001) and long term (MD: 17.80, 95% CI: 8.36-27.23, p = 0.0002). A higher proportion of surgical patients had some sort of pain relief compared with those who had endoscopy, both at medium term (72% vs. 46%, RR: 1.51, 95% CI: 1.19-1.90, p = 0.0006) and long term (73% vs. 47%, RR: 1.50, 95% CI: 1.19-1.89, p = 0.0007). Complete pain relief was more common in the surgical group compared to the endoscopy group, both at medium term (33% vs. 17%, RR: 1.97, 95% CI: 1.16-3.36, p = 0.01) and long term (35% vs. 18%, RR: 1.92, 95% CI: 1.15-3.20, p = 0.01). The pooled crossover rate from endoscopy to surgery was 22% (22/99). CONCLUSIONS Surgical treatment in patients with painful CP leads to better pain control, requiring fewer interventions as compared to endoscopic treatment.

Reduced bone mineral density in the first year after total pancreatectomy with islet autotransplantation (TPIAT). Pancreatology 2021; 21:1491-1497. [PMID: 34538580 PMCID: PMC8629939 DOI: 10.1016/j.pan.2021.08.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 07/29/2021] [Accepted: 08/28/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND/OBJECTIVES The effect of total pancreatectomy with islet autotransplantation (TPIAT) on bone mineral density (BMD) in patients with CP is unknown. We aimed to assess bone health in patients with CP after TPIAT. METHODS We measured BMD, BMD Z-score, and bone mineral content (BMC) for total body, lumbar spine, right and left hip in 78 patients before and after TPIAT using dual-energy X-ray absorptiometry (DXA, n = 78 pre-TPIAT, n = 65 paired pre- and 12 months post-TPIAT, n = 33 paired 12 and 18 months post-TPIAT), and tested for association with clinical history including age, smoking status, and medications using paired and two-sample t-tests, linear regression, and Fisher's exact test. Laboratory measures related to bone health were also assessed. RESULTS In the patients with pre-TPIAT DXA, 12% had low BMD (Z-score ≤ -2). BMD, BMD Z-score, and BMC all decreased from pre-to 12 months post-TPIAT. BMD declined by 1.7%-4.1% with the greatest change at the hips. Adjusted for change in lean and fat body mass, DXA changes remained significant for total body and hip. Serum carboxy-terminal collagen crosslinks telopeptide and alkaline phosphatase increased at 12 months post-TPIAT, suggesting possible increased bone remodeling. BMD, BMD Z-score, and BMC did not change between 12 months and 18 months in any of the four regions (p > 0.6). CONCLUSIONS TPIAT is associated with decreases in BMD in the body, lumbar, and hip regions of patients with CP in the first year after TPIAT but these appear to stabilize between 12 and 18 months after TPIAT.

Peripancreatic arterial pseudoaneurysm in the background of chronic pancreatitis: clinical profile, management, and outcome. Updates Surg 2021; 74:1367-1373. [PMID: 34816352 DOI: 10.1007/s13304-021-01208-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 11/18/2021] [Indexed: 01/04/2023]
Abstract
BACKGROUND Bleeding pseudoaneurysm (PSA) is a rare but potentially lethal complication of chronic pancreatitis (CP). It requires expeditious management by a multidisciplinary team. The study aims to report our experience with PSA in the background of CP. METHODS All the patients, who underwent intervention for CP-related PSA between August 2007 and December 2020 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India were retrospectively reviewed. RESULTS Of the total 26 patients, 25 (96%) were men with a median age of 38 (11-63) years. The most commonly involved vessel was the splenic artery (n = 18, 69%). The interval between onset of GI bleed and intervention was 7 (0-120) days. Embolization was attempted in 11(42%) patients and was successful in six patients. Surgery was performed in 20 (77%) patients including five patients after failed embolization. The most commonly performed operation was distal pancreatectomy with splenectomy. The median operating time was 216 (115-313) minutes. The median intraoperative blood loss was 325 (100-1000) ml. Seventeen (85%) patients' required intraoperative blood transfusion. Four patients in the embolization group and five patients in the surgical group developed procedure-related complications. The most common postoperative complication was wound infection followed by pancreatic fistula. There was no procedure-related death. Over a median follow-up of 24 (6-122) months, no patient developed recurrent hemorrhage. CONCLUSIONS Both embolization and surgery play an important role in the management of PSA. The choice of procedure depends upon the local availability and feasibility of a particular technique.

Abstract
This report investigates an unusual case of recurrent pancreatitis. A 22-year-old female was admitted to the emergency room for severe abdominal pain, nausea, and weight loss. She reported having these symptoms since she was a toddler. The clinician ordered fecal pancreatic elastase-1, fat-soluble vitamins, molecular studies, and imaging of the pancreas by computed tomography. The screening test result for fecal pancreatic elastase-1 revealed severe pancreatic exocrine insufficiency, and the concentrations of fat-soluble vitamins were also low. Imaging showed scattered calcifications in the pancreas. These findings supported a diagnosis of chronic pancreatitis. Due to the rarity of chronic pancreatitis in young adults, molecular studies were performed. The patient was found to be homozygous for a mutation in the SPINK1 gene, which is associated with hereditary pancreatitis. This case report discusses hereditary pancreatitis and highlights data on the utilization of fecal pancreatic elastase-1 to assess pancreatic exocrine insufficiency.

Clin Res Hepatol Gastroenterol 2020; 44:598-608. [PMID: 31523018 DOI: 10.1016/j.clinre.2019.08.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 07/20/2019] [Accepted: 08/14/2019] [Indexed: 02/06/2023]
Abstract
AIMS Islet autotransplantation (IAT), in conjunction with total pancreatectomy (TP), is used to relieve pain in patients with chronic pancreatitis (CP), while reducing the incidence of brittle diabetes. We aimed to evaluate the efficacy and safety of IAT after TP (TPIAT) in this setting. METHODS We searched PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials since 1977. Data were extracted from published papers. Random-effects meta-analysis and meta-regression models were built to assess the outcomes and effect of different factors. Subgroup and sensitivity analyses were conducted to examine the between-study heterogeneity, which was assessed using Cochrane's Q and I2 statistic. RESULTS A total of 17 studies, including 1024 patients, met the eligibility criteria. The median cohort size was 21 patients (range: 5-409). The pooled incidence rates of insulin independence, narcotic independence and mortality at last follow-up were 11.47 per 100 patient-years (95% CI: 6.79-21.60, I2=91.0%), 18.11 per 100 patient-years (95% CI: 5.29-62.04, I2=98.8%) and 2.88 per 100 patient-years (95% CI: 1.75-4.74, I2=46.8%), respectively. However, the heterogeneity level of our results was high, which was due to differences in research methods and definitions of outcomes between studies. Therefore, our results should be interpreted with caution. CONCLUSIONS TPIAT can effectively relieve pain and reduce the risk of surgical diabetes with no increase in mortality or morbidity. Prospective, randomized, clinical trials are required to further evaluate selection of patients and the timing of TPIAT.

Abstract
PURPOSE OF REVIEW While there has been a growing utilization of total pancreatectomy with islet autotransplantation (TPIAT) for patients with medically refractory chronic pancreatitis over the past few decades, there remains a lack of consensus clinical guidelines to inform the counseling and management of patients undergoing TPIAT. In this article, we review the current clinical practice and published experience of several TPIAT centers, outline key aspects in managing patients undergoing TPIAT, and discuss the glycemic outcomes of this procedure. RECENT FINDINGS Aiming for lower inpatient glucose targets immediately after surgery (usually 100-120 mg/dl), maintaining all patients on subcutaneous insulin for at least 3 months to "rest" islets before an attempt is made to wean insulin, and close outpatient endocrinology follow-up after TPIAT particularly in the first year is common and related to better outcomes. Although TPIAT procedures and glycemic outcomes may differ across surgical centers, overall, approximately one third of patients are insulin independent at 1 year after TPIAT. Higher islet yield and lower preoperative glucose levels are among the strongest predictors of short-term post-operative insulin independence. Beyond 1 year post-operatively, the clinical management and long-term glycemic outcomes of patients after TPIAT are more variable. A multidisciplinary approach is essential in optimizing the preoperative, inpatient, and post-operative management and counseling of patients about the expected glycemic outcomes after surgery. Consensus guidelines for the clinical management of diabetes after TPIAT and harmonization of data collection protocols among TPIAT centers are needed to address the current knowledge gaps in clinical care and research and to optimize glycemic outcomes after TPIAT.

Abstract
Chronic pancreatitis and incidentally discovered pancreatic lesions present significant diagnostic and therapeutic challenges for surgeons. While both decompressive and resection procedures have been described for treatment of chronic pancreatitis, optimal management must be tailored to each patient's individual disease characteristics, parenchymal morphology, and ductal anatomy. Surgeons should strive to achieve long-lasting pain relief while preserving native pancreatic function. For patients with incidentally discovered pancreatic lesions, differentiating benign, pre-malignant, and malignant lesions is critical as earlier treatment is thought to result in improved survival. The purpose of this evidence-based manuscript is to review the presentation, workup, surgical management, and associated outcomes for patients with chronic pancreatitis or incidentally discovered solid and cystic lesions of the pancreas.

Abstract
Introduction Chronic pancreatitis (CP) is an intractable and multi-factorial disorder. Developing appropriate animal models is an essential step in pancreatitis research, and the best ones are those which mimic the human disorder both aetiologically and pathophysiologically. The current study presents an optimised protocol for creating a murine model of CP, which mimics the initial steps of chronic pancreatitis in alcohol chronic pancreatitis and compares it with two other mouse models treated with cerulein or ethanol alone. Material and methods Thirty-two male C57BL/6 mice were randomly selected, divided into four groups, and treated intraperitoneally with saline (10 ml/kg, control group), ethanol (3 g/kg; 30% v/v), cerulein (50 µg/kg), or ethanol + cerulein, for six weeks. Histopathological and immunohistochemical assays for chronic pancreatitis index along with real-time PCR assessments for mRNA levels of inflammatory cytokines and fibrogenic markers were conducted to verify the CP induction. Results The results indicated that CP index (CPI) was significantly increased in ethanol-cerulein mice compared to the saline, ethanol, and cerulein groups (p < 0.001). Interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), transforming growth factor β (TGF-β), α-smooth muscle actin (α-SMA), and myeloperoxidase activity were also significantly greater in both cerulein and ethanol-cerulein groups than in the saline treated animals (p < 0.001). Immunohistochemical analysis revealed enhanced expression of TGF-β and α-SMA in ethanol-cerulein mice compared to the saline group. Conclusions Intraperitoneal (IP) injections of ethanol and cerulein could successfully induce CP in mice. IP injections of ethanol provide higher reproducibility compared to ethanol feeding. The model is simple, non-invasive, reproducible, and time-saving. Since the protocol mimics the initial phases of CP development in alcoholics, it can be used for investigating basic mechanisms and testing new therapies.

Abstract
The aim of the study was to assess the rate of insulin independence in patients after total pancreatectomy (TP) and islet autotransplantation in our center. TP followed by islet auto-transplantation was performed in 10 patients. Severe unrelenting pain associated with chronic pancreatitis was the major indication for surgery. Islets were isolated using the modified Ricordi method and infused through the portal vein. Exogenous insulin therapy was implemented for at least two months posttransplant to support islet engraftment and was subsequently weaned off, if possible. Median follow-up was 26 months (range, 2 to 60 months). Median islet yield was 158,860 islet equivalents (IEQ) (range, 40,203 to 330,472 IEQ) with an average islet yield of 2,478 IEQ/g (range, 685 to 6,002 IEQ/g) of processed pancreas. One patient developed transient partial portal vein thrombosis, which resolved without sequela. Five (50%) patients are currently off insulin with excellent glucose control and HbA1c below 6. Patients who achieved and maintained insulin independence were transplanted with significantly more islets (median, 202,291 IEQ; range, 145,000 to 330,474 IEQ) than patients who required insulin support (64,348 IEQ; range, 40,203 to 260,476 IEQ; P < 0.05). Patient body mass index and time of chronic pancreatitis prior transplant procedure did not correlate with the outcome. The remaining five patients, who require insulin support, had present C-peptide in blood and experience good glucose control without incidence of severe hypoglycemic episodes. Islet autotransplantation efficiently preserved beta cell function in selected patients with chronic pancreatitis and the outcome correlated with transplanted islet mass.

Abstract
Magnetic resonance (MR) imaging plays an important role in the diagnosis and staging of acute and chronic pancreatitis and may represent the best imaging technique in the setting of pancreatitis due to its unmatched soft tissue contrast resolution as well as non-ionizing nature and higher safety profile of intravascular contrast media, making it particularly valuable in radiosensitive populations such as pregnant patients, and patients with recurrent pancreatitis requiring multiple follow-up examinations. Additional advantages include the ability to detect early forms of chronic pancreatitis and to better differentiate adenocarcinoma from focal chronic pancreatitis. This review addresses new trends in clinical pancreatic MR imaging emphasizing its role in imaging all types of acute and chronic pancreatitis, pancreatitis complications and other important differential diagnoses that mimic pancreatitis.

Abstract
BACKGROUND/OBJECTIVES Pancreatectomy with autologous islet transplantation has slowly been proving to be an effective way of treating chronic pancreatitis while lessening the effects of the concomitant surgical diabetes of pancreatectomy alone. Assessing patient quality of life and pain after the procedure is particularly important as intractable pain is the main complaint for which patients undergo total pancreatectomy. METHODS We used the Rand SF-36 and McGill pain questionnaires, and Visual Analogue Scale to assess patients preoperatively for quality of life and pain resulting from life with chronic pancreatitis. After undergoing total pancreatectomy with autologous islet transplantation (TPAIT), patients were followed with surveys administered at 1 month, 6 months, and 1 year to evaluate changes in their quality of life and pain experienced. RESULTS Significant improvement was reported in all components of every questionnaire within a year after surgery. Furthermore, patient reported mean scores on quality of life were found to fall within the range of the general population. CONCLUSIONS From our experience with 53 patients at the University of Arizona, after pancreatectomy with autologous islet transplantation patients reported a higher quality of life when compared to preoperative values, as well as reduced levels of pain.

Abstract
The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Abstract
AIM: To obtain reference values for pancreatic flow output rate (PFR) and peak time (PT) in healthy volunteers and chronic pancreatitis (CP); to correlate quantification of secretin enhanced magnetic resonance cholangiopancreatography (SMRCP) of pancreatic fluid output following secretin with fecal elastase-1 (FE-1) tests.
METHODS: The present study includes 53 subjects comprised of 17 healthy individuals and 36 patients with CP from April 2011 to January 2013. The 36 patients with CP were divided into three groups of mild CP (n = 14), moderate CP (n = 19) and advanced CP (n = 3) by M-ANNHEIM classification for CP.. Fifty-three cases underwent FE-1 test and magnetic resonance imaging using 3.0 T-device (Signa EXCITE, GE Healthcare). Coronal T2-weighted single-shot turbo spin-echo, spiratory triggered, covering the papillae, duodenum and small bowel. MRCP was performed with a heavily T2-weighted fat-suppressed long TE HASTE sequence (thick slab 2D MRCP sequence), repeated every 2 min up to 11 min after 0.1 mL/kg secretin injection (Secrelux, Sanochemia®, Germany). FE-1 test used sandwich enzyme-linked immunosorbent assay (ELISA) test (ScheBo. Tech®, Germany).
RESULTS: A good linear correlation showed between the calculated volume and the actual volume by Phantom experiments. Fifty-three paired Quantification of secretin enhanced magnetic resonance cholangiopancreatography (MRCPQ) and FE-1 data sets were analyzed. The mean FE-1 of 53 cases was 525.41 ± 94.44 μg/g for 17 healthy volunteers, 464.95 ± 136.13 μg/g for mild CP, 301.55 ± 181.55 μg/g for moderate CP, 229.30 ± 146.60 μg/g for advanced CP. Also, there was statistically significant difference in FE-1 (P = 0.0001) between health and CP. The mean values of PFR and PT were 8.18 ± 1.11 mL/min, 5.76 ± 1.71 min for normal; 7.27 ± 2.04 mL/min, 7.71 ± 2.55 min for mild CP; 4.98 ± 2.57 mL/min, 9.10 ± 3.00 min for moderate CP; 4.13 ± 1.83 mL/min, 12.33 ± 1.55 min for advanced CP. Further, statistically significant difference in PFR (P = 0.0001) and PT (P = 0.0001) was observed between health and CP. Besides, there was correlation (r = 0.79) and consistency (K = 0.6) between MRCPQ and ELISA Test. It was related between M-ANNHEIM classification and PFR (r = 0.55), FE-1 (r = 0.57).
CONCLUSION: SMRCP can provide a safe, non-invasive and efficient method to evaluate the exocrine function of the pancreas.

Abstract
Background Human ß-defensins are a family of antimicrobial peptides located at the mucosal surface. Both sequence multi-site variations (MSV) and copy-number variants (CNV) of the defensin-encoding genes are associated with increased risk for various diseases, including cancer and inflammatory conditions such as psoriasis and acute pancreatitis. In a case–control study, we investigated the association between MSV in DEFB104 as well as defensin gene (DEF) cluster copy number (CN), and pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP). Results Two groups of PDAC (N=70) and CP (N=60) patients were compared to matched healthy control groups CARLA1 (N=232) and CARLA2 (N=160), respectively. Four DEFB104 MSV were haplotyped by PCR, cloning and sequencing. DEF cluster CN was determined by multiplex ligation-dependent probe amplification. Neither the PDAC nor the CP cohorts show significant differences in the DEFB104 haplotype distribution compared to the respective control groups CARLA1 and CARLA2, respectively. The diploid DEF cluster CN exhibit a significantly different distribution between PDAC and CARLA1 (Fisher’s exact test P=0.027), but not between CP and CARLA2 (P=0.867). Conclusion Different DEF cluster b CN distribution between PDAC patients and healthy controls indicate a potential protective effect of higher CNs against the disease.

Abstract
For patients with severe chronic pancreatitis refractory to medical interventions, total pancreatectomy can be considered to relieve the root cause of pain. The goal of a simultaneous islet autotransplant is to prevent or minimize the otherwise inevitable surgical diabetes. Islet autotransplant can successfully preserve some endogenous islet function in the majority of recipients, which mediates protection against brittle diabetes. Most maintain reasonably good glycemic control, while 30 %-40 % successfully discontinue insulin therapy. With islet autotransplants reaching a wider clinical audience, refinements in islet isolation techniques and strategies to protect islet grafts post-transplant may further improve the success of this procedure.

Abstract
BACKGROUND Total pancreatectomy (TP) with intraportal islet autotransplantation (IAT) can relieve pain and preserve β-cell mass in patients with chronic pancreatitis (CP) when other therapies fail. We report on a >30-year single-center series. STUDY DESIGN Four hundred and nine patients (including 53 children, 5 to 18 years) with CP underwent TP-IAT from February 1977 to September 2011 (etiology: idiopathic, 41%; Sphincter of Oddi dysfunction/biliary, 9%; genetic, 14%; divisum, 17%; alcohol, 7%; and other, 12%; mean age was 35.3 years, 74% were female; 21% has earlier operations, including 9% Puestow procedure, 6% Whipple, 7% distal pancreatectomy, and 2% other). Islet function was classified as insulin independent for those on no insulin; partial, if known C-peptide positive or euglycemic on once-daily insulin; and insulin dependent if on standard basal-bolus diabetic regimen. A 36-item Short Form (SF-36) survey for quality of life was completed by patients before and in serial follow-up since 2007, with an integrated survey that was added in 2008. RESULTS Actuarial patient survival post TP-IAT was 96% in adults and 98% in children (1 year) and 89% and 98% (5 years). Complications requiring relaparotomy occurred in 15.9% and bleeding (9.5%) was the most common complication. IAT function was achieved in 90% (C-peptide >0.6 ng/mL). At 3 years, 30% were insulin independent (25% in adults, 55% in children) and 33% had partial function. Mean hemoglobin A1c was <7.0% in 82%. Earlier pancreas surgery lowered islet yield (2,712 vs 4,077/kg; p = 0.003). Islet yield (<2,500/kg [36%]; 2,501 to 5,000/kg [39%]; >5,000/kg [24%]) correlated with degree of function with insulin-independent rates at 3 years of 12%, 22%, and 72%, and rates of partial function 33%, 62%, and 24%. All patients had pain before TP-IAT and nearly all were on daily narcotics. After TP-IAT, 85% had pain improvement. By 2 years, 59% had ceased narcotics. All children were on narcotics before, 39% at follow-up; pain improved in 94%; and 67% became pain-free. In the SF-36 survey, there was significant improvement from baseline in all dimensions, including the Physical and Mental Component Summaries (p < 0.01), whether on narcotics or not. CONCLUSIONS TP can ameliorate pain and improve quality of life in otherwise refractory CP patients, even if narcotic withdrawal is delayed or incomplete because of earlier long-term use. IAT preserves meaningful islet function in most patients and substantial islet function in more than two thirds of patients, with insulin independence occurring in one quarter of adults and half the children.

Abstract
BACKGROUND/AIM Chronic pancreatitis (CP) is the progressive and irreversible destruction of the pancreas characterized by the permanent loss of endocrine and exocrine function. Trypsin, the most important digestive enzyme plays a central role in the regulation of all other digestive enzymes. Chymotrypsin, an endopeptidase hydrolyzes peptides at amino acids with aromatic side chains. Alpha-1-antitrypsin is a principal antiprotease which protects the mucosal tissue from the proteolytic effects of trypsin and chymotrypsin by the formation of molar complexes. The present study is aimed at examining the role of proteases (trypsin and chymotrypsin) and anti-protease (α1-anti-trypsin) in the etiopathogenesis of chronic pancreatitis. PATIENTS AND METHODS A total of 90 CP patients and 110 age and sex matched controls were considered for the study. Serum trypsin, chymotrypsin and α1-anti-trypsin levels were determined prospectively in CP patients and compared to healthy controls as described previously. RESULTS The mean activity of trypsin were found to be increased in CP patients (X ± SD = 0.82 ± 0.838) in comparison to normal control group (X ± SD = 0.55 ± 0.328), (P = 0.001). Chymotrypsin activity were also found to be elevated in CP patients (X ± SD = 0.63 ± 0.278) in comparison to control group (X ± SD = 0.39 ± 0.295), (P = 0.0001). The mean α-1-anti-trypsin activity were found to be lowered in CP patients (X ± SD = 0.42 ± 0.494) in comparison to control group (X ± SD = 0.67 ± 0.465), with the variation being significant (P = 0.0003). CONCLUSION The findings suggest an imbalance in the synthesis and degradation of proteolytic enzymes and antiprotease indicating an altered aggressive and defensive role in the pathogenesis of chronic pancreatitis.

Abstract
Alterations in the pancreatic fluid proteome of individuals with chronic pancreatitis (CP) may offer insights into the development and progression of the disease. The endoscopic pancreatic function test (ePFT) can safely collect large volumes of pancreatic fluid that are potentially amenable to proteomic analyses using difference gel electrophoresis (DIGE) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pancreatic fluid was collected endoscopically using the ePFT method following secretin stimulation from three individuals with severe CP and three chronic abdominal pain (CAP) controls. The fluid was processed to minimize protein degradation and the protein profiles of each cohort, as determined by DIGE and LC-MS/MS, were compared. This DIGE-LC-MS/MS analysis reveals proteins that are differentially expressed in CP compared with CAP controls. Proteins with higher abundance in pancreatic fluid from CP individuals include: actin, desmoplankin, α-1-antitrypsin, SNC73, and serotransferrin. Those of relatively lower abundance include carboxypeptidase B, lipase, α-1-antichymotrypsin, α-2-macroglobulin, actin-related protein (Arp2/3) subunit 4, glyceraldehyde-3-phosphate dehydrogenase, and protein disulfide isomerase. Endoscopic collection (ePFT) in tandem with DIGE-LC-MS/MS is a suitable approach for pancreatic fluid proteome analysis; however, further optimization of our protocol, as outlined herein, may improve proteome coverage in future analyses.

Abstract
Chronic pancreatitis is a rare disease in childhood. However, when severe, a total pancreatectomy may be the only option to relieve pain and restore quality of life. An islet autotransplant performed at the time of pancreatectomy can prevent or minimize the postsurgical diabetes that would otherwise result from pancreatectomy alone. In this procedure, the resected pancreas is mechanically disrupted and enzymatically digested to separate the islets from the surrounding exocrine tissue, and the isolated islets are infused into the portal vein and engraft in the liver. Because patients are receiving their own tissue, no immunosuppression is required. Islet autotransplant is successful in two thirds of children-these patients are insulin independent or require little insulin to maintain euglycemia. Factors associated with a more successful outcome include a younger age at transplant (<13 years), more islets transplanted, and lack of prior surgical procedures on the pancreas (partial pancreatectomy or surgical drainage procedures).

Abstract
BACKGROUND For chronic pancreatitis, European prospective trials have concluded that duodenum-preserving head resections (DPHR) are associated with less morbidity and similar pain relief and quality of life (QoL) outcomes compared with pancreaticoduodenectomy (PD). However, DPHR procedures are seldom performed in North America. METHODS Patients undergoing PD or DPHR for unremitting pain secondary to chronic pancreatitis were retrospectively identified. Quality of life was assessed cross-sectionally using the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire (QLQ-C30) and pancreatic cancer-specific supplemental module (QLQ-PAN26). RESULTS Eighty-one patients underwent either a Whipple PD (n= 59) or a DPHR (Bern, Beger or Frey procedure, n= 22) for the treatment of pain caused by chronic pancreatitis over a 5-year period. The characteristics of patients undergoing DPHR and PD procedures were similar. Duration of procedure (360 min vs. 245 min), duration of hospital stay (12.0 days vs. 9.5 days) and estimated blood loss (535 ml vs. 214 ml) were all significantly less for DPHR patients (P < 0.05). Thirty-day morbidity and mortality, postoperative pain relief and QoL scores did not differ significantly between groups. CONCLUSIONS Duodenum-preserving head resection is equally as effective as PD in relieving pain and improving QoL in chronic pancreatitis patients, and involves a shorter hospital stay and less blood loss.

Abstract
OBJECTIVES A multicenter study was initiated by the Chinese Chronic Pancreatitis Study Group to determine the nature and magnitude of chronic pancreatitis (CP) in China. METHODS Twenty-two hospitals representing all 6 urban health care regions in China participated in the study. The survey covered a 10-year period from May 1, 1994, to April 30, 2004. Multiple logistic regression was used for analyses. RESULTS The analysis included 2008 patients (64.99% were men, and 35.01% were female; mean age, 48.9 years [SD, 15.0 years]). Chronic pancreatitis prevalence increased yearly from 1996 to 2003: 3.08, 3.91, 5.28, 7.61, 10.43, 11.92, 12.84, and 13.52 per 100,000 inhabitants. Chronic pancreatitis etiologies were alcohol (35.11%), biliary stones (34.36%), hereditary (7.22%), and idiopathic CP (12.90%). Clinical feature were pain (76.25%), maldigestion (36.11%), jaundice (13.40%), and steatorrhea (6.92%). Complications were pseudocyst (26.25%), diabetes (21.61%), bile duct strictures (13.40%), and ascites (1.74%). With regard to the diagnosis, the sensitivity and specificity of endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography were 88% and 93%, and 87% and 93%, respectively. Three hundred ninety-one patients (19.47%) received endoscopic therapy. Surgery was performed in 239 patients (11.90%). CONCLUSION In China, the incidence of CP is rising rapidly; alcohol and biliary stones are the main causes. Endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography are highly sensitive and specific diagnostic methods.

Abstract
Chronic pancreatitis (CP) is characterized by progressive, chronic inflammation of the pancreas, resulting in loss of exocrine and endocrine function and chronic abdominal pain. In most cases, CP is induced by long-term alcoholism. The second most frequent diagnosis is idiopathic CP, in the absence of known causes of CP. However, the identification of genetic and immunological causes continuously reduces the number of cases classified as idiopathic pancreatitis. Common symptoms of CP comprise abdominal pain radiating to the back, diarrhea, steatorrhea and the development of diabetes. The diagnosis is mainly based on clinical features, typical morphological findings such as pancreatic calcifications, duct stenoses and dilatations, as well as pathologic pancreatic function tests. Treatment of CP includes watch and wait strategies in asymptomatic patients, symptomatic treatment of the clinical features such as pain, exocrine and endocrine insufficiency, as well as interventional or surgical therapy of complications such as pseudocysts, pancreatic duct stenosis, stones or biliary obstruction.

Abstract
AIM: To test the hypothesis that calcium sensing receptor (CASR) polymorphisms are associated with chronic pancreatitis (CP), and to determine whether serine protease inhibitor Kazal 1type (SPINK1) N34S or alcohol are necessary co-factors in its etiology.
METHODS: Initially, 115 subjects with pancreatitis and 66 controls were evaluated, of whom 57 patients and 21 controls were predetermined to carry the high-risk SPINK1 N34S polymorphism. We sequenced CASR gene exons 2, 3, 4, 5 and 7, areas containing the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 controls to analyze three common nonsynonymous single nucleotide polymorphisms (SNPs) in exon 7 (A986S, R990G, and Q1011E).
RESULTS: The CASR exon 7 R990G polymorphism was significantly associated with CP (OR, 2.01; 95% CI, 1.12-3.59; P = 0.015). The association between CASR R990G and CP was stronger in subjects who reported moderate or heavy alcohol consumption (OR, 3.12; 95% CI, 1.14-9.13; P = 0.018). There was no association between the various CASR genotypes and SPINK1 N34S in pancreatitis. None of the novel CASR polymorphisms reported from Germany and India was detected.
CONCLUSION: Our United States-based study confirmed an association of CASR and CP and for the first time demonstrated that CASR R990G is a significant risk factor for CP. We also conclude that the risk of CP with CASR R990G is increased in subjects with moderate to heavy alcohol consumption.

Abstract
The incidence of chronic pancreatitis (CP) is increasing all over the world. However, it is rather difficult to treat it because its etiological factor and pathogenesis are still unclear. In recent years, the rapid advances in endoscopy techniques have provided new treatment modalities for CP. We, in this paper, describe the present status and advances in endoscopy for CP as well as the problems and difficulties, thus contributing to the treatment for CP.

Abstract
BACKGROUND Pancreatic fistula (PF) formation is a known complication of pancreatic surgery, pancreatitis, and pancreatic injury. When medical or endoscopic interventions fail to resolve PF, operation remains the only viable treatment option. Unfortunately, operation for the correction of PF is often difficult and associated with significant morbidity. METHODS Herein, we report on our experience with a previously described technique for the management of PF that is performed easily and is associated with reduced morbidity. During the period of 2003-2006, 8 patients (males = 6, female = 2) with PF were treated with prolonged percutaneous drainage. Once a mature scar tract formed around the percutaneous drain, patients underwent a fistulojejunostomy. RESULTS The age of these patients ranged from 43 to 61 years. Of the 8 patients, 5 had fistulas secondary to necrotizing pancreatitis. The remaining 3 patients had fistulas resulting from previous pancreatic surgery. The average interval between drain placement and fistulojejunostomy was 6 months (range, 4-7 months). The average duration of operation was 2.5 h (range, 1-4.5 h). The average blood loss was 280 mL (range, 50-600 mL). Average duration of stay was 9 days (average, 4-14 days). At a mean follow-up of 17 months (range, 2-58 months), 6 of 8 patients had resolution of their pancreatic fistulas, could resume regular diet, and were free of narcotic use. One patient developed a recurrent pseudocyst and required a distal pancreatectomy, and the final patient was lost to follow-up. CONCLUSIONS Fistulojejunostomy is an effective therapy for the definitive treatment of pancreatic fistulas.

Abstract
BACKGROUND Pancreas divisum is the most common anatomic variant of pancreatic development and may lead to pancreatitis. This study evaluated the efficacy of endoscopic stenting in patients with chronic pancreatitis due to pancreas divisum. METHODS Between 1993 and 2005, 32 patients with chronic pancreatitis due to pancreas divisum were treated with endoscopic stenting. Each patient underwent an endoscopic retrograde cholangiopancreatography to confirm the diagnosis of pancreas divisum prior to endoscopic stenting. A survey was conducted by telephone conversation to evaluate pain intensity, symptom relief, hospital admissions, quality of life and pain medication usage, which was verified by a statewide narcotic electronic database. Eight of the 32 patients were unavailable for the interview and were not included in the analysis of the study. Results are expressed as mean +/- standard error of the mean (SEM). RESULTS Twenty-four patients were followed up for a period of 59.6 months. The overall pain level average in the 24 patients decreased significantly from 8.9 +/- 0.4 pre-stenting to 3.9 +/- 0.7 post-stenting (P < 0.05) on a scale of 1 to 10. The number of hospital admissions per year in these patients decreased significantly from 7.3 +/- 2.1 pre-stenting to 2.1 +/- 0.4 post-stenting (P < 0.05). Pain medication usage reported by the patients found a decrease in 58% of patients, 21% remained the same, and 13% increased their usage. There was improvement in nausea (67%), vomiting (63%), and chronic pain (75%). Thirteen patients (55%) were treated endoscopically without requiring surgery and 11 (45%) patients required surgery after stenting. These 11 patients had surgery an average of 25 months post-stenting. The complication rate of post-procedural pancreatitis was 3.4%. No mortality was reported in this study. CONCLUSION Endoscopic stenting of the pancreatic duct is a safe and effective first treatment for patients with pancreatitis secondary to pancreas divisum. Surgery, when performed for endoscopic stenting failure, is effective as an adjunctive treatment.

Abstract
BACKGROUND/PURPOSE To explore the etiology, age and gender distribution, complications, and prognosis of recurrent pediatric pancreatitis. METHODS Between 1993 and 2005, 92 children were hospitalized at the National Taiwan University Hospital with pancreatitis. Only 25 diagnosed with recurrent pancreatitis, based on two or more episodes of pancreatitis, elevated serum amylase and/or lipase levels > or = 3 times the upper limit of normal, radiographic evidence, and clinical symptoms, were enrolled. RESULTS A total of 85 episodes of pancreatitis in 25 patients (16 girls, 9 boys; mean age, 9.5 +/- 4.4 years; 3.4 +/- 1.9 episodes per person) were documented. The recurrence rate of pediatric pancreatitis was 27.2%. Recurrent pancreatitis was associated with pancreaticobiliary structural anomalies (n = 7), biliary stones or sludge (n = 4), hyperlipidemia (n = 3), pseudopapillary tumor of the pancreas (n = 2), trauma (n = 2), hypoxic encephalopathy with recurrent bacteremia and sepsis (n = 1), and idiopathic (n = 6). The age and gender distribution according to etiologies were not different (p = 0.301 for age, p = 0.137 for gender). Complications included cholangitis or cholestasis (16%), pancreatic necrosis (16%), pseudocyst formation (12%), shock (8%), hemorrhagic pancreatitis (4%), and diabetes mellitus (4%). No patient died of recurrent pancreatitis. Long-term morbidity after recurrent pancreatitis presented as gout, diabetes mellitus, non-alcoholic steatohepatitis, and chronic pancreatitis. CONCLUSION For children who suffer from recurrent pancreatitis, pancreaticobiliary structural anomalies should be considered first.
