Abstract
Pain secondary to chronic pancreatitis is a poorly understood and complex phenomenon. Current endoscopic treatments target pancreatic duct decompression secondary to strictures, stones, or inflammatory and neoplastic masses. When there is refractory pain and other treatments have been unsuccessful, one can consider an endoscopic ultrasound-guided celiac plexus block. Data on the latter are underwhelming.

Abstract
Pancreatic duct pressure (PDP) dynamics comprise an intricately modulated system that helps maintain homeostasis of pancreatic function. It is affected by various factors, including the rate of pancreatic fluid secretion, patency of the ductal system, sphincter of Oddi function, and pancreatic fluid characteristics. Disease states such as acute and chronic pancreatitis can alter the normal PDP dynamics. Ductal hypertension or increased PDP is suspected to be involved in the pathogenesis of pancreatic pain, endocrine and exocrine pancreatic insufficiency, and recurrent pancreatitis. This review provides a comprehensive appraisal of the available literature on PDP, including the methods used in the measurement and clinical implications of elevated PDP.

Abstract
Stone clearance with extracorporeal shock wave lithotripsy is a safe and effective procedure for large pancreatic calculi not extractable by the standard endoscopic retrograde cholangiopancreatography techniques. In properly selected patients, this minimally invasive approach should be offered as the first line of therapy instead of surgery. Complete stone clearance can be achieved in three-fourths with long-term pain relief in two-thirds of patients. Re-intervention is required in less than half of the patients. Future studies should compare the extracorporeal approach with intraductal lithotripsy using the pancreatoscope.

Abstract
INTRODUCTION Pancreatic duct obstruction is the primary indication for endoscopic and/or surgical therapy in patients with chronic pancreatitis (CP). However, the clinical course of medically managed patients in relation to pancreatic duct obstruction is largely unknown. METHODS This was a retrospective cohort study of medically managed patients with CP. We classified patients based on pancreatic duct obstruction from a stricture or stone using cross-sectional imaging (i.e., large vs small duct CP). We compared prevalence of diabetes and exocrine insufficiency (EPI) between subgroups at inclusion and investigated risk of new-onset diabetes, EPI, and all-cause mortality over a follow-up period of 5 years. Changes in pancreatic morphology were studied in patients who underwent follow-up imaging. RESULTS A total of 198 patients (mean age 58 ± 12 years, 70% male, 60% alcoholic etiology, 38% large duct CP) were evaluated. At inclusion, patients with large vs small duct CP had a higher prevalence of both diabetes (43% vs 24%, P = 0.004) and EPI (47% vs 28%, P = 0.007). There was an increased risk of new-onset EPI in patients with large duct CP (hazard ratio 1.72; 95% confidence interval [1.05-2.80], P = 0.031) and higher rates of pancreatic atrophy ( P < 0.001). No differences between groups were observed for new-onset diabetes and all-cause mortality. Conversion from small to large duct CP or vice versa during follow-up was observed in 14% of patients. DISCUSSION In a medically managed cohort of patients, large duct CP was associated with increased risk of EPI and pancreatic atrophy compared with small duct CP.

Abstract
DESCRIPTION The purpose of this American Gastroenterological Association (AGA) Clinical Practice Update Expert Review is to provide practical, evidence-based guidance to clinicians regarding the role of endoscopy for recurrent acute and chronic pancreatitis. METHODS This expert review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide guidance on a topic of clinical importance to the AGA membership, underwent internal peer review by the Clinical Practice Updates Committee (CPUC), and external peer review through standard procedures of Gastroenterology. This review is framed around the 8 best practice advice points agreed upon by the authors, based on the results of randomized controlled trials, observational studies, systematic reviews and meta-analyses, as well expert consensus in this field. Best Practice Advice Statements BEST PRACTICE ADVICE 1: After an unrevealing initial evaluation, endoscopic ultrasound is the preferred diagnostic test for unexplained acute and recurrent pancreatitis. Magnetic resonance imaging with contrast and cholangiopancreatography is a reasonable complementary or alternative test to endoscopic ultrasound, based on local expertise and availability. BEST PRACTICE ADVICE 2: The role of endoscopic retrograde cholangiopancreatography (ERCP) for reducing the frequency of acute pancreatitis episodes in patients with pancreas divisum is controversial, but minor papilla endotherapy may be considered, particularly for those with objective signs of outflow obstruction, such as a dilated dorsal pancreatic duct and/or santorinicele. There is no role for ERCP to treat pain alone in patients with pancreas divisum. BEST PRACTICE ADVICE 3: The role of ERCP for reducing the frequency of pancreatitis episodes in patients with unexplained recurrent acute pancreatitis and standard pancreatic ductal anatomy is controversial and should only be considered after a comprehensive discussion of the uncertain benefits and potentially severe procedure-related adverse events. When pursued, ERCP with biliary sphincterotomy alone may be preferable to dual sphincterotomy. BEST PRACTICE ADVICE 4: Surgical intervention should be considered over endoscopic therapy for long-term treatment of patients with painful obstructive chronic pancreatitis. Endoscopic intervention is a reasonable alternative to surgery for suboptimal operative candidates or those who favor a less invasive approach, assuming they are clearly informed that the best practice advice primarily favors surgery. BEST PRACTICE ADVICE 5: When ERCP is pursued, small (≤5mm) main pancreatic duct stones can be treated with pancreatography and conventional stone extraction maneuvers. For larger stones, extracorporeal shockwave lithotripsy and/or pancreatoscopy with intraductal lithotripsy may be required. BEST PRACTICE ADVICE 6: When ERCP is pursued, prolonged stent therapy (6-12 months) is effective for treating symptoms and remodeling main pancreatic duct strictures. The preferred approach is to place and sequentially add multiple plastic stents in parallel (upsizing); emerging evidence suggests that fully covered self-expanding metal stents may have a role for this indication, but additional research is necessary. BEST PRACTICE ADVICE 7: ERCP with stent insertion is the preferred treatment for benign biliary stricture due to chronic pancreatitis. FCSEMS placement is favored over multiple plastic stents whenever feasible, given similar efficacy but significantly reduced need for stent exchange procedures during the treatment course. BEST PRACTICE ADVICE 8: Celiac plexus block should not be routinely performed for the management of pain due to chronic pancreatitis. The decision to proceed with celiac plexus block in selected patients with debilitating pain in whom other therapeutic measures have failed can be considered on a case-by-case basis, but only after discussion of the unclear outcomes of this intervention and its procedural risks.

Prevalence of primary painless chronic pancreatitis: A systematic review and meta-analysis. Pancreatology 2022; 22:20-29. [PMID: 34840065 PMCID: PMC8785146 DOI: 10.1016/j.pan.2021.11.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 11/12/2021] [Accepted: 11/15/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND/OBJECTIVES While pain is the predominant symptom of chronic pancreatitis (CP), a subset of patients may experience a painless course. This systematic review aimed to determine the prevalence of primary painless CP. METHODS MEDLINE (PubMed), EMBASE and Web of Science Core Collection databases were searched for published studies through September 15, 2020 that included at least 10 consecutive patients with CP and which reported the number with painless CP. The presence of a history of recurrent acute pancreatitis (RAP), exocrine pancreatic insufficiency (EPI), diabetes mellitus (DM) and pancreatic adenocarcinoma (PA) in the painless CP patients was also recorded. A random effects model was used to determine pooled prevalence estimates with 95% confidence intervals (95% CI). RESULTS Among the 5057 studies identified and screened, 42 full-text articles were included in the final analysis. There were a total of 14,277 patients with CP among whom 1569 had painless CP. The pooled prevalence of painless CP was 12% (95% CI 10-15%). Among a subset of studies that reported on calcifications (n = 11), DM (n = 12), EPI (n = 8) and history of RAP (n = 14), the pooled prevalence estimates were 96% (95% CI 73-100%), 51% (95% CI 32-70%), and 47% (95% CI 15-81%), respectively. Alcohol, idiopathic/genetic and other etiologies were attributed to be the cause of painless CP in 32.4%, 56.9% and 8.9% patients, respectively. CONCLUSION Approximately one in ten patients with CP have primary painless disease with the majority being attributable to an idiopathic/genetic etiology. Further research is needed to determine the optimal management of these patients.

Abstract
Chronic pancreatitis (CP) is an inflammatory process characterized by irreversible morphological changes in the pancreas. Pain is the predominant symptom observed during the course of CP. The etiopathogenesis of pain in CP is multifactorial and includes ductal hypertension due to obstruction of the pancreatic duct (PD), neuropathic causes, and extrapancreatic complications of CP like pseudocyst and distal biliary obstruction. A sizeable proportion of patients with CP are amenable to endoscopic treatment. The mainstay of endotherapy includes decompression of PD with one or more plastic stents in those with stricture, and fragmentation of PD calculi using extracorporeal shock wave lithotripsy. Nearly two-thirds of the patients achieve pain relief in the long term with endotherapy. Upfront assessment for the suitability of endotherapy is paramount to achieve the best outcomes. The predictors of poor response to endotherapy include multifocal disease, like those with multifocal strictures or multiple calculi throughout the pancreas, or a combination of both PD strictures and stones. With the emerging use of covered metal stents, the outcomes are likely to improve in cases with refractory PD strictures as well as CP-related distal biliary obstruction. The optimum stent design and indwell time of metal stents in cases with refractory PD strictures need further evaluation. Endoscopic ultrasonography has emerged as a complementary endoscopic modality in the management of CP as well as associated complications like pseudocysts, refractory pain, and vascular complications.
