Abstract
Endoscopic therapy is the first line of management for chronic pancreatitis (CP)-related benign biliary strictures. Multiple plastic stents (MPS) exchanged at regular intervals and temporary placement of fully covered self-expanding metal stents (FCSEMS) are preferred modalities of endotherapy. FCSEMS placement is non-inferior to MPS and requires fewer sessions of endoscopic retrograde cholangiopancreatography than MPS placement. The presence of head calcifications, severe CP, and length of stricture are predictors of failure or recurrence after endotherapy. Failure of endotherapy should be considered after 1 year when surgery should be considered.

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.

Self-expanding metallic stent for refractory pancreatic duct stricture in chronic pancreatitis: A prospective follow-up study. Indian J Gastroenterol 2023:10.1007/s12664-023-01445-6. [PMID: 37768445 DOI: 10.1007/s12664-023-01445-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 08/08/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND AND AIMS In chronic pancreatitis, fully covered self-expanding metal stents (FCSEMS) are used to treat refractory pancreatic duct strictures. However, the FCSEMS design, effectiveness, safety, optimal stent indwelling time and patient selection remain unclear. This study aimed at evaluating technical success, clinical success and adverse events with FCSEMS in patients with symptomatic pancreatic duct stricture. METHODS The prospective study was conducted between May 2017 and May 2021 at a tertiary care center for chronic pancreatitis with refractory pancreatic duct stricture using controlled radial expansion (CRE) endoscopic retrograde cholangiopancreatography (ERCP) with FCSEMS (Niti-S, Bumpy stent, Taewoong Medical, Gimpo-Si, South Korea). RESULTS During the study period, a total of 11 patients underwent ERCP with FCSEMS for refractory pancreatic duct stricture. The mean age (± standard deviation, [SD]) was 32.36 ± 10.98 years and nine patients (81%) were male. Technical and clinical success rates were 100% and 90.9%, respectively. All patients had a history of prior pancreatic endotherapy. The median (inter quartile range, [IQR]) stent indwell time was seven (6-10) months. The median visual analogue scale (VAS) pain score pre and post-FCSEMS was 8 (5-8) and 1 (0-2), respectively (p-value 0.003). Median (IQR) follow-up after stent removal was 48 (40-60) months. One patient (9%) developed de novo main pancreatic duct (MPD) stricture, which was asymptomatic. None of the patients had cholangitis, pancreatitis, perforation, proximal migration or stent fracture. CONCLUSION The FCSEMS treatment appears to be safe, feasible and possibly an effective option for patients who have not responded to endoscopic plastic stenting.

Abstract
Chronic pancreatitis has been shown to cause various pathologies, such as biliary strictures and pancreatic malignancies, which can in turn result in biliary outlet obstruction. However, a pancreatic calculus itself resulting in biliary obstruction has been far less observed. The patient in question had a documented history of chronic alcoholism and received a cholecystectomy decades prior to the onset of cholestatic symptoms. Cholangiography demonstrated no indication of biliary stricture formation, nor was there radiological evidence of pancreatic pseudocyst or malignant formation. CT evidence across a decade of time established a storyline of pancreatic calculi formation, migration, and resultant biliary obstruction. Subsequent endoscopic sphincterectomy, pancreatic calculi removal, and biliary tree stent placement resulted in laboratory value normalization and clinical symptom resolution.

Abstract
Endoscopic luminal stenting (ELS) represents a minimally invasive option for the management of malignant obstruction along the gastrointestinal tract. Previous studies have shown that ELS can provide rapid relief of symptoms related to esophageal, gastric, small intestinal, colorectal, biliary, and pancreatic neoplastic strictures without compromising cancer patients’ overall safety. As a result, in both palliative and neoadjuvant settings, ELS has largely surpassed radiotherapy and surgery as a first-line treatment modality. Following the abovementioned success, the indications for ELS have gradually expanded. To date, ELS is widely used in clinical practice by well-trained endoscopists in managing a wide variety of diseases and complications, such as relieving non-neoplastic obstructions, sealing iatrogenic and non-iatrogenic perforations, closing fistulae and treating post-sphincterotomy bleeding. The abovementioned development would not have been achieved without corresponding advances and innovations in stent technology. However, the technological landscape changes rapidly, making clinicians’ adaptation to new technologies a real challenge. In our mini-review article, by systematically reviewing the relevant literature, we discuss current developments in ELS with regard to stent design, accessories, techniques, and applications, expanding the research basis that was set by previous studies and highlighting areas that need to be further investigated.

Abstract
Chronic pancreatitis is a slow, irreversible, and progressive inflammatory condition with abdominal pain, loss of parenchyma, fibrosis, and calculus formation. It also causes loss of exocrine and endocrine function. Gallstones and alcohol is the most frequent cause of chronic pancreatitis. It is also caused by other factors, including oxidative stress, fibrosis, and repeated incidence of acute pancreatitis. Chronic pancreatitis is followed by several sequelae, one of them being formation of calculi in the pancreas. The formation of calculi can occur in the main pancreatic duct, branches of the duct, and parenchyma. The cardinal sign of chronic pancreatitis is pain caused by obstruction of pancreatic ducts and its branches leading to ductal hypertension resulting in pain. The main aim of endotherapy includes pancreatic duct decompression. The management options vary based on the type and size of the calculus. The treatment of choice for small-sized pancreatic calculi is endoscopic retrograde cholangiopancreatography (ERCP) followed by sphincterotomy and extraction. The large-sized calculi need fragmentation before extraction, which is done by extracorporeal shock wave lithotripsy (ESWL). Surgery can be an option for patients having severe pancreatic calculi if endoscopic therapy fails. For diagnostic purposes, imaging plays a very important role. The treatment options remain complex if the radiological and laboratory findings overlap. Due to advancements in diagnostic imaging, treatment options have become precise and helpful. It can significantly lower the quality of life along with immediate and long-term problems that pose a serious risk to life. This review comprises the various management options available for removing calculi following chronic pancreatitis, including surgical, endoscopic, and medical therapy.

Abstract
Background/Aims This study assessed the significance of biliary stricture in symptomatic chronic pancreatitis patients requiring extracorporeal shock wave lithotripsy (ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) to remove obstructing pancreatic calculi. Methods A total of 97 patients underwent ESWL followed by ERCP to remove pancreatic calculi between October 2014 and October 2017 at Virginia Mason Medical Center. Significant biliary stricture (SBS) was defined as a stricture with upstream dilation on computed tomography scan or magnetic resonance cholangiopancreatography scans accompanied by cholestasis and/or cholangitis. SBS was initially managed by either a plastic stent or fully covered self-expandable metallic stent (fcSEMS). If the stricture did not resolve, the stent was replaced with either multiple plastic stents or another fcSEMS. Data were collected by retrospectively reviewing the medical records. Results Biliary strictures were noted in approximately one-third of patients (34/97, 35%) undergoing ESWL for pancreatic calculi. Approximately one-third of the biliary strictures (11/34, 32%) were SBS. Pseudocysts were more frequently found in those with SBS (36% vs 8%, p=0.02), and all pseudocysts in the SBS group were located in the pancreatic head. The initial stricture resolution rates with fcSEMSs and plastic prostheses were 75% and 29%, respectively. The overall success rate for stricture resolution was 73% (8/11), and the recurrence rate after initial stricture resolution was 25% (2/8). Conclusions Although periductal fibrosis is the main mechanism underlying biliary stricture development in chronic pancreatitis, inflammation induced by obstructing pancreatic calculi, including pseudocysts, is an important contributing factor to SBS formation during the acute phase.

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.

Abstract
Pancreatolithiasis, or pancreatic calculi (PC), is a sequel of chronic pancreatitis (CP) and may occur in the main ducts, side branches or parenchyma. Calculi are the end result, irrespective of the etiology of CP. PC contains an inner nidus surrounded by successive layers of calcium carbonate. These calculi obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Both endoscopic therapy and surgery aim to clear these calculi and decrease ductal hypertension. In small PC, endoscopic retrograde cholangiopancreatography (ERCP) followed by sphincterotomy and extraction is the treatment of choice. Large calculi require fragmentation by extracorporeal shock wave lithotripsy (ESWL) prior to their extraction or spontaneous expulsion. In properly selected cases, ESWL followed by ERCP is the standard of care for the management of large PC. Long-term outcomes following ESWL have demonstrated good pain relief in approximately 60% of patients. However, ESWL has limitations. Per oral pancreatoscopy and intraductal lithotripsy represent techniques in evolution, and in current practice their use is limited to centers with considerable expertise. Surgery should be offered to all patients with extensive PC, associated multiple ductal strictures or following failed endotherapy.

Abstract
Benign biliary strictures are a common indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has evolved over the last 2 decades as the current standard of care. The most common etiologies of strictures encountered are following surgery and those related to chronic pancreatitis. High-quality cross-sectional imaging provides a road map for endoscopic management. Currently, sequential placement of multiple plastic biliary stents represents the preferred approach. There is an increasing role for the treatment of these strictures using covered metal stents, but due to conflicting reports of efficacies as well as cost and complications, this approach should only be entertained following careful consideration. Optimal management of strictures is best achieved using a team approach with the surgeon and interventional radiologist playing an important role.

Abstract
This article aims to elucidate the classification of and optimal treatment for pancreatic pseudocysts. Various approaches, including endoscopic drainage, percutaneous drainage, and open surgery, have been employed for the management of pancreatic pseudocysts. However, no scientific classification of pancreatic pseudocysts has been devised, which could assist in the selection of optimal therapy. We evaluated the treatment modalities used in 893 patients diagnosed with pancreatic pseudocysts according to the revision of the Atlanta classification in our department between 2001 and 2010. All the pancreatic pseudocysts have course of disease >4 weeks and have mature cysts wall detected by computed tomography or transabdominal ultrasonography. Endoscopic drainage, percutaneous drainage, or open surgery was selected on the basis of the pseudocyst characteristics. Clinical data and patient outcomes were reviewed. Among the 893 patients, 13 (1.5%) had percutaneous drainage. Eighty-three (9%) had type I pancreatic pseudocysts and were treated with observation. Ten patients (1%) had type II pseudocysts and underwent the Whipple procedure or resection of the pancreatic body and tail. Forty-six patients (5.2%) had type III pseudocysts: 44 (4.9%) underwent surgical internal drainage and 2 (0.2%) underwent endoscopic drainage. Five hundred six patients (56.7%) had type IV pseudocysts: 297 (33.3%) underwent surgical internal drainage and 209 (23.4%) underwent endoscopic drainage. Finally, 235 patients (26.3%) had type V pseudocysts: 36 (4%) underwent distal pancreatectomy or splenectomy and 199 (22.3%) underwent endoscopic drainage. A new classification system was devised, based on the size, anatomical location, and clinical manifestations of the pancreatic pseudocyst along with the relationship between the pseudocyst and the pancreatic duct. Different therapeutic strategies could be considered based on this classification. When clinically feasible, endoscopic drainage should be considered the optimal management strategy for pancreatic pseudocysts.

Abstract
BACKGROUND AND AIMS Refractory chronic pancreatitis has been proposed as a challenge for endoscopists following routine single plastic stenting. However, data on the efficacy and safety of further endoscopic stenting are still controversial. The current systematic review aimed to assess the efficacy and safety of placement of fully covered self-expandable metal stent (FCSEMS) and multiple plastic stents. METHODS Databases including MEDLINE, EMBASE, the Cochrane Library, CBM, CNKI, VIP, and WANFANG Database were used to search relevant trials. Published studies were assessed by using well-defined inclusion and exclusion criteria. The process was independently performed by two investigators. RESULTS A total of 5 studies provided data of 80 patients. Forest plots and publication bias were not carried out because few studies were relevant and screened studies were all case series. The technical success rate was 100% both in placement of FCSEMS and multiple plastic stents. The functional success rate after placement of FCSEMS was 100%, followed by multiple plastic stents (94.7%). Complications occurred 26.2% after FCSEMS placement, which was not described in detail in multiple plastic stents. The stent migration rate was 8.2% for FCSEMS and 10.5% for multiple plastic stents. Reintervention rate was 9.8% for FCSEMS and 15.8% for multiple plastic stents. Pain improvement rate was 85.2% for FCSEMS and 84.2% for multiple plastic stents. CONCLUSIONS FCSEMS appeared to be no significant difference with multiple plastic stents in treatment of refractory chronic pancreatitis. We need to develop more investigations.

Abstract
Chronic pancreatitis is progressive and irreversible, leading to digestive and absorptive disorders by destruction of the exocrine pancreas and to diabetes mellitus by destruction of the endocrine pancreas. When complications such as pancreatolithiasis and pseudocyst occur, elevated pancreatic ductal pressure exacerbates pain and induces other complications, worsening the patient's general condition. Combined treatment with extracorporeal shock-wave lithotripsy and endoscopic lithotripsy is a useful, minimally invasive, first-line treatment approach that can preserve pancreatic exocrine function. Pancreatic duct stenosis elevates intraductal pressure and favor both pancreatolithiasis and pseudocyst formation, making effective treatment vitally important. Endoscopic treatment of benign pancreatic duct stenosis stenting frequently decreases pain in chronic pancreatitis. Importantly, stenosis of the main pancreatic duct increases risk of stone recurrence after treatment of pancreatolithiasis. Recently, good results were reported in treating pancreatic duct stricture with a fully covered self-expandable metallic stent, which shows promise for preventing stone recurrence after lithotripsy in patients with pancreatic stricture. Chronic pancreatitis has many complications including pancreatic carcinoma, pancreatic atrophy, and loss of exocrine and endocrine function, as well as frequent recurrence of stones after treatment of pancreatolithiasis. As early treatment of chronic pancreatitis is essential, the new concept of early chronic pancreatitis, including characteristics findings in endoscopic ultrasonograms, is presented.

Abstract
Chronic pancreatitis (CP)-related common bile duct (CBD) strictures are more difficult to treat endoscopically compared with benign biliary strictures because of their nature, particularly in patients with calcific CP. Before any attempt at treatment, malignancy must be excluded. Single plastic stents can be used for immediate symptom relief and as "bridge to surgery and/or bridge to decision," but are not suitable for definitive treatment of CP-related CBD strictures because of long-term poor results. Temporary simultaneous placement of multiple plastic stents has a high technical success rate and provides good long-term results.

Abstract
Chronic pancreatitis (CP) is a common gastrointestinal illness, which affects the quality of life with substantial morbidity and mortality. The management includes medical, endoscopic and surgical approaches with the need for interaction between various specialties, calling for a concerted multidisciplinary approach. However, at the time of this publication, guidelines to establish care of these patients are lacking. This review provides the reader with a comprehensive overview of the studies summarizing the various treatment options available, including medical, surgical and endoscopic options. In addition, technological advances such as endoscopic retrograde cholangiopancreatogrophy, endoscopic shock wave lithotripsy and endoscopic ultrasound can now be offered with reasonable success for pancreatic decompression, stricture dilatation with stent placement, stone fragmentation, pseudocyst drainage, and other endoscopic interventions such as celiac plexus block for pain relief. We emphasize the endoscopic options in this review, and attempt to extract the most up to date information from the current literature. The treatment of CP and its complications are discussed extensively. Complications such as biliary strictures. pancreatic pseudocysts, and chronic pain are common issues that arise as long-term complications of CP. These often require endoscopic or surgical management and possibly a combination of approaches, however choosing amongst the various therapeutic and palliative modalities while weighing the risks and benefits, makes the management of CP challenging. Treatment goals should be not just to control symptoms but also to prevent disease progression. Our aim in this paper is to advocate and emphasize an evidence based approach for the management of CP and associated long term complications.

Abstract
Chronic pancreatitis (CP) is a complex disease with a wide range of clinical manifestations. This range comprises from asymptomatic patients to patients with disabling symptoms or complications. The management of CP is frequently different between geographic areas and even medical centers. This is due to the paucity of high quality studies and clinical practice guidelines regarding its diagnosis and treatment. The aim of the Spanish Pancreatic Club was to give current evidence-based recommendations for the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts on this disease. These experts were selected according to clinical and research experience in CP. A list of questions was made and two experts reviewed each question. A draft was later produced and discussed with the entire panel of experts in a face-to-face meeting. The level of evidence was based on the ratings given by the Oxford Centre for Evidence-Based Medicine. In the second part of the consensus, recommendations were given regarding the management of pain, pseudocysts, duodenal and biliary stenosis, pancreatic fistula and ascites, left portal hypertension, diabetes mellitus, exocrine pancreatic insufficiency, and nutritional support in CP.

Abstract
Obstructive jaundice is very rarely caused by impaction of a pancreatic stone in the papilla. We report here on a case of obstructive jaundice with acute cholangitis that was caused by an impacted pancreatic stone in the papilla in a patient with chronic pancreatitis. A 48-year-old man presented with acute obstructive cholangitis. Abdominal computed tomography with the reconstructed image revealed distal biliary obstruction that was caused by a pancreatic stone in the pancreatic head, and there was also pancreatic ductal dilatation and parenchymal atrophy of the pancreatic body and tail with multiple calcifications. Emergency duodenoscopy revealed an impacted pancreatic stone in the papilla. Precut papillotomy using a needle knife was performed, followed by removal of the pancreatic stone using grasping forceps. After additional sphincterotomy, a large amount of dark-greenish bile juice gushed out. The patient rapidly improved and he has remained well.

Abstract
Pancreatic duct stones are a common complication during the natural course of chronic pancreatitis and often contribute to additional pain and pancreatitis. Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused in part by obstruction of the pancreatic duct system (by stones or strictures) resulting in increasing intraductal pressure and parenchymal ischemia. Pancreatic stones can be managed by surgery, endoscopy, or extracorporeal shock wave lithotripsy. In this review, updated management of pancreatic duct stones is discussed.

Abstract
BACKGROUND/AIMS Pancreatic duct calcifications are common in chronic pancreatitis. Secretin (SEC) stimulates pancreas duct cells to secrete bicarbonate-rich fluid. SEC may aid fragmentation and facilitate excretion of pulverized pancreatic stones during extracorporeal shock wave lithotripsy (ESWL). The aim was to evaluate the effect of SEC administered during ESWL on clearance of main pancreatic stone (MPDS) at endoscopic retrograde cholangiopancreatography (ERCP). METHODS Between Jan. 2003 and Sept. 2010, patients with MPDS who were treated with ESWL and ERCP were identified retrospectively. The number and diameter of calcifications were assessed at pre-ESWL images. Before 2006, ESWL was performed without SEC stimulation. From 2007, 16 μg of SEC was administered IV near the beginning of ESWL at the discretion of the managing physician. Clearance of the pancreatic duct was assessed with ERCP after ESWL. RESULTS A total of 233 consecutive cases (SEC group: 71, no SEC group: 162) were tallied. Overall there were 310 ESWLs and 332 ERCPs in the 233 cases. On univariate analysis, the use of SEC showed significantly higher rate of complete MPDS clearance (63% vs. 46%, p = 0.021) after first ESWL/ERCP. The number of repeat sessions of ESWL/ERCP was similar between the two groups (SEC vs. No SEC, ESWL/ERCP: 1.27 vs. 1.36/1.34 vs. 1.46). Independent predictors of complete/nearly complete stone clearance included the use of SEC (p = 0.005), pre-ESWL pancreatic stent (p = 0.001). CONCLUSIONS Secretin during ESWL appears to aid clearance of MPDS in chronic calcific pancreatitis. Further prospective randomized studies would be of interest.

Abstract
Chronic pancreatitis (CP) is a debilitating disease that can result in chronic abdominal pain, malnutrition, and other related complications. The main aims of treatment are to control symptoms, prevent disease progression, and correct any complications. A multidisciplinary approach involving medical, endoscopic, and surgical therapy is important. Endoscopic therapy plays a specific role in carefully selected patients as primary interventional therapy when medical measures fail or in patients who are not suitable for surgery. Endoscopic therapy is also used as a bridge to surgery or as a means to assess the potential response to pancreatic surgery. This review addresses the role of endoscopic therapy in relief of obstruction of the pancreatic duct (PD) and bile du ct, closure of PD leaks, and drainage of pseudocysts in CP. The role of endoscopic ultrasound-guided celiac plexus block for pain in chronic pancreatitis is also discussed.

Abstract
Extraction of large pancreatic and common bile duct (CBD) calculi has always challenged the therapeutic endoscopist. Extracorporeal shockwave lithotripsy (ESWL) is an excellent tool for patients with large pancreatic and CBD calculi that are not amenable to routine endotherapy. Pancreatic calculi in the head and body are targeted by ESWL, with an aim to fragment them to < 3 mm diameter so that they can be extracted by subsequent endoscopic retrograde cholangiopancreatography (ERCP). In our experience, complete clearance of the pancreatic duct was achieved in 76% and partial clearance in 17% of 1006 patients. Short-term pain relief with reduction in the number of analgesics ingested was seen in 84% of these patients. For large CBD calculi, a nasobiliary tube is placed to help target the calculi, as well as bathe the calculi in saline - a simple maneuver which helps to facilitate fragmentation. The aim is to fragment calculi to < 5 mm size and clear the same during ERCP. Complete clearance of the CBD was achieved in 84.4% of and partial clearance in 12.3% of 283 patients. More than 90% of the patients with pancreatic and biliary calculi needed three or fewer sessions of ESWL with 5000 shocks being delivered at each session. The use of epidural anesthesia helped in reducing patient movement. This, together with the better focus achieved with newer third-generation lithotripters, prevents collateral tissue damage and minimizes the complications. Complications in our experience with nearly 1300 patients were minimal, and no extension of hospital stay was required. Similar rates of clearance of pancreatic and biliary calculi with minimal adverse effects have been reported from the centers where ESWL is performed regularly. In view of its high efficiency, non-invasive nature and low complication rates, ESWL can be offered as the first-line therapy for selected patients with large pancreatic and CBD calculi.

Abstract
Biliary plastic stenting plays a key role in the endoscopic management of benign biliary diseases. Complications following surgery of the biliary tract and liver transplantation are amenable to endoscopic treatment by plastic stenting. Insertion of an increasing number of plastic stents is currently the method of choice to treat postoperative biliary strictures. Benign biliary strictures secondary to chronic pancreatitis or primary sclerosing cholangitis may benefit from plastic stenting in select cases. There is a role for plastic stent placement in nonoperative candidates with acute cholecystitis and in patients with irretrievable bile duct stones.

Abstract
Use of stents in the pancreas has been confined and limited to referral centers that specialize in the treatment of patients with severe pancreatitis and acute relapsing pancreatitis. With therapeutic development in endoscopic treatment of pancreatic diseases and a better understanding of the cause and prevention of ERCP related complications, the use of stents has been extended to transmural drainage of pancreatic fluid collection or of pancreatic ducts has well as to prophylaxis of post-ERCP pancreatitis. As a result, indication for pancreatic stenting and the kind of stents to be used as well as the followup after placement varies. This article reviews the major indication for pancreatic stent placement and focuses on the choice of stent, technique of implantation and followup.

Abstract
Plastic stent insertion is a treatment option for pancreatic duct stricture with chronic pancreatitis. However, recurrent stricture is a limitation after removing the plastic stent. Self-expandable metal stents have long diameters and patency. A metal stent has become an established management option for pancreatic duct stricture caused by malignancy but its use in benign stricture is still controversial. We introduce a young patient who had chronic pancreatitis and underwent several plastic stent insertions due to recurrent pancreatic duct stricture. His symptoms improved after using a fully covered self-expandable metal covered stent and there was no recurrence found at follow-up at the outpatient department.

Abstract
This paper gives practical guidelines for diagnosis and treatment of chronic pancreatitis. Statements have been elaborated by working teams of experts, by searching for and analysing the literature, and submitted to a consensus process by using a Delphi modified procedure. The statements report recommendations on clinical and nutritional approach, assessment of pancreatic function, treatment of exocrine pancreatic failure and of secondary diabetes, treatment of pain and prevention of painful relapses. Moreover, the role of endoscopy in approaching pancreatic pain, pancreatic stones, duct narrowing and dilation, and complications was considered. Recommendations for most appropriate use of various imaging techniques and of ultrasound endoscopy are reported. Finally, a group of recommendations are addressed to the surgical treatment, with definition of right indications, timing, most appropriate procedures and techniques in different clinical conditions and targets, and clinical and functional outcomes following surgery.

Abstract
Over the last 15 years, endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a diagnostic tool to one that is primarily used to provide therapy. This development occurred first for biliary disorders and subsequently to a lesser extent for pancreatic diseases. Computed tomography, magnetic resonance imaging, magnetic resonance cholangiopancreatography and endoscopic ultrasonography suggest a diagnosis in the majority of patients with pancreatic diseases today and can help physicians and patients avoid unnecessary ERCP. However, a selected number of patients with pancreatic diseases may benefit from pancreatic endotherapy and avoid complex surgery and chronic use of medications. Pancreatic sphincterotomy, pancreatic stenting and pancreatic cyst drainage are some of the most effective and challenging endoscopic pancreatic interventions and should be performed with caution by expert therapeutic endoscopists. There has been a paucity of randomized studies investigating endoscopic techniques in comparison with surgery and medical therapy for the treatment of most benign and malignant pancreatic disorders due to the limited number of patients and the expertise required to attempt these procedures.

Abstract
AIM Large pancreatic ductal calculi and pain are a feature of chronic calcific pancreatitis (CCP) in the tropics. This large single center study evaluates the role of extracorporeal shock wave lithotripsy (ESWL) in fragmentation of large pancreatic stones and relief of pain in patients with CCP. METHODS Patients with CCP presenting with pain and large pancreatic duct (PD) calculi (>5 mm diameter) not amenable to extraction at routine endoscopic retrograde cholangio pancreatography (ERCP) were taken up for ESWL using a 3rd generation lithotripter. Stones in the head and body of pancreas were targeted at ESWL; 5,000 shocks were given per session. The calculi were fragmented to <3 mm size and then cleared by endotherapy. Pancreatic duct stents were deployed when indicated. A total of 1,006 patients underwent ESWL. Complete clearance was achieved in 762 (76%), partial clearance in 173 (17%) and unsuccessful in the rest. More than 962 (90%) of patients needed less than three sessions of ESWL. At 6 months, 711 (84%) of 846 patients who returned for follow up had significant relief of pain with a decrease in analgesic use. Complications were mild and minimal. CONCLUSION ESWL is an effective and safe modality for fragmentation of large PD calculi in patients with CCP.

Abstract
BACKGROUND Fully covered self-expandable metal stent (FCSEMS) placement has recently been tried in the management of refractory pancreatic-duct strictures associated with advanced chronic pancreatitis. The major limitation of FCSEMSs was frequent migration. OBJECTIVE To assess the safety, migration rate, and removability of modified FCSEMSs with antimigration features used for the treatment of benign pancreatic-duct strictures. DESIGN Prospective study. SETTING Tertiary academic center. PATIENTS Thirty-two patients with chronic painful pancreatitis and dominant ductal stricture. INTERVENTIONS Transpapillary endoscopic placement of FCSEMSs in the pancreatic duct with removal after 3 months. MAIN OUTCOME MEASUREMENTS Technical and functional success and adverse events associated with the placement of metal stents. RESULTS FCSEMSs were successfully placed in all patients through the major (n = 27) or minor (n = 5) duodenal papilla. All patients achieved pain relief from stent placement. There was no occurrence of stent-induced pancreatitis or pancreatic sepsis. No stent migrated, and all stents were easily removed. Follow-up ERCP 3 months after stent placement showed resolution of duct strictures in all patients. Pancreatograms obtained at FCSEMS removal displayed de novo focal pancreatic duct strictures in 5 patients, but all were asymptomatic. LIMITATIONS No long-term follow-up. CONCLUSIONS Temporary 3-month placement of FCSEMSs was effective in resolving pancreatic-duct strictures in chronic pancreatitis, with an acceptable morbidity profile. Modified FCSEMSs can prevent stent migration, but may be associated with de novo duct strictures. Further trials are needed to assess long-term safety and efficacy.

Abstract
OBJECTIVE Endoscopic therapy with pancreatic duct (PD) stenting in painful chronic pancreatitis is effective at reducing pain. Few studies have compared response to different PD stent diameters. In this study, we retrospectively analyzed the effect of PD stent diameter on hospitalization for abdominal pain in chronic pancreatitis. METHODS An existing database was queried to identify individuals who received PD stenting for chronic pancreatitis. Each patient was grouped according to stent diameter: (1) 8.5F stents or smaller and (2) 10F stents. The main outcome was number of hospitalizations adjusting for varying follow-up time and controlling for age, sex, and etiology of pancreatitis using a negative binomial model. RESULTS One hundred sixty-three patients underwent PD stent placement for chronic pancreatitis from October 1995 to September 2007. One hundred twenty-nine patients (79%) received predominantly PD stents 8.5F or smaller in diameter, and 34 patients (21%) received predominantly PD stents 10F in diameter. There was no statistically significant difference in population characteristics between the 2 groups. The 10F stent group had a statistically significant (P = 0.003) lower rate of hospitalization. CONCLUSIONS Patients who received larger diameter PD stents had fewer hospitalizations for abdominal pain. Outcome-based prospective studies are needed.

Abstract
Pancreaticobiliary ductal diseases are largely investigated by indirect imaging techniques. Therefore, the pathology of up to 30% of cases remains undetermined. Cholangiopancreatoscopy allows direct visualization of ductal abnormalities with the ability to sample tissue and deliver a number of endotherapies. The technique can be broadly categorized into either two-operator or single-operator systems. Both systems provide important diagnostic information in the investigation of undetermined biliary or pancreatic strictures, intraductal papillary mucinous neoplasia, occult ductal malignant changes in patients with primary sclerosing cholangitis and occult intraductal stones in patients with complex biliary stone diseases. Therapeutically, cholangiopancreatoscopy-guided endotherapies provide a highly effective and safe alternative to surgery for patients with difficult extrahepatic and intrahepatic ductal stones that are not amenable to conventional endoscopic extraction by endoscopic retrograde cholangiopancreatography. The clinical application of cholangiopancreatoscopy, however, will be limited unless the technology is further refined to improve its durability, image quality, therapeutic capability and technical feasibility.

Feasibility and safety of placement of a newly designed, fully covered self-expandable metal stent for refractory benign pancreatic ductal strictures: a pilot study (with video). Gastrointest Endosc 2008; 68:1182-9. [PMID: 19028228 DOI: 10.1016/j.gie.2008.07.027] [Citation(s) in RCA: 95] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2008] [Accepted: 07/10/2008] [Indexed: 02/08/2023]
Abstract
BACKGROUND Painful chronic pancreatitis with main pancreatic ductal strictures is usually managed with endotherapy with a plastic stent. To date, the role of placement of metallic stents, especially uncovered ones in benign pancreatic ductal stricture, has been unsatisfactory as a result of stent dysfunction related to mucosal hyperplasia. OBJECTIVE We explored the feasibility and safety of temporary placement of a newly designed, fully covered self-expandable metal stent (FCSEMS) in painful chronic pancreatitis and refractory benign pancreatic ductal strictures. DESIGN A prospective pilot and feasibility study. SETTING A tertiary academic center. PATIENTS Thirteen patients with chronic painful pancreatitis of alcoholic (8) or idiopathic (5) etiology. INTERVENTION ERCP with temporary FCSEMS placement (2 months). Endoscopic removal of FCSEMSs was performed with a snare or rat-tooth forceps. MAIN OUTCOME MEASUREMENTS End points were feasibility, safety, and morbidity. RESULTS Successful FCSEMS placement was performed in all enrolled patients. After immediate placement of FCSEMS, 2 patients had mild acute pancreatitis related mainly to the stricture dilation procedure (Soehendra stent retriever or balloon dilation). Complications associated with stent placement included 5 migrations (39%, 1 proximal and 4 distal) and 2 incidents of cholestatic liver dysfunction associated with the compression of the bile duct orifice by expansion of FCSEMSs. In 1 patient with proximal migration, the stent was repositioned by an inflated retrieval balloon. Additional endoscopic biliary sphincterotomy with or without biliary stenting was performed in 2 patients with cholestatic liver dysfunction. There was no occurrence of pancreatic sepsis among any patients. FCSEMSs were removed from 9 of 9 patients without stent migration (100% [9/9] as per protocol, and 69% [9/13] as intention to treat, respectively). Improvement or resolution of the pancreatic ductal strictures was confirmed in all 13 patients on follow-up ERCP (2 months after stent placement), regardless of stent migration. LIMITATIONS Small patient populations without long-term follow-up. CONCLUSIONS Two-month placement of FCSEMSs in patients with refractory benign pancreatic ductal strictures may be feasible and relatively safe. However, stent migration was not uncommon. A further investigation with ideal stent design may therefore be needed before recommending FCSEMSs as a therapeutic option for refractory benign pancreatic ductal strictures.

A novel biodegradable pancreatic stent for human pancreatic applications: a preclinical safety study in a large animal model. Gastrointest Endosc 2008; 67:1106-12. [PMID: 18291398 DOI: 10.1016/j.gie.2007.10.013] [Citation(s) in RCA: 30] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2006] [Accepted: 10/02/2007] [Indexed: 02/08/2023]
Abstract
BACKGROUND Endoscopic stenting is one treatment method for pancreatic strictures or pseudocysts in patients with symptomatic chronic pancreatitis. With a biodegradable stent, the later removal of the stent could be avoided. OBJECTIVE We investigated the degradation, patency, and toxicity of a novel biodegradable, self-expanding radiopaque polylactide-barium sulfate pancreatic stent in a large animal model. DESIGN Animal study. SETTING AND INTERVENTIONS Five swine had a biodegradable pancreatic stent placed into the pancreatic duct (PD) and were followed-up for 6 months. MAIN OUTCOME MEASUREMENTS Repeated blood tests and radiographs were studied during the follow-up. The animals were euthanized at 6 months, at which time, the PD inner diameter was measured, and histology was analyzed and graded. For comparison, histology from 5 nonstented animals was also analyzed. RESULTS The stent was correctly inserted into the PD in 4 of 5 animals. All the animals remained healthy, gained weight, and showed no signs of pancreatitis. A radiograph showed that the stent was in its original place in all animals at 1 month but had disappeared in all animals by 3 months. At 6 months, the autopsied pancreatic tissue was soft, and the PD was patent in all of the animals. The PD was slightly dilated at the site of the stent in the head of the pancreas compared with the preoperative diameter (5 mm [range 3-6 mm] vs 2 mm [range 1-3 mm], P < .05), but, in the body of the pancreas, no significant dilatation was seen. In the histology of the pancreata, there was no difference between the samples from the exposed parts of the biodegradable pancreatic stent compared with the distal nonexposed parts, or to the samples from the nonstented animals. CONCLUSIONS This novel biodegradable pancreatic stent, studied in these swine, appeared to be safe for use in the PD. These encouraging results warrant further clinical trials with this biodegradable pancreatic stent in pancreatic applications in human beings.

Abstract
PURPOSE OF REVIEW As in our previous reviews, we endeavor to review important new observations in chronic pancreatitis made in the past year. Topics recently reviewed were truncated to accommodate a surge in publications on clinical aspects of chronic pancreatitis, which contained new observations or insights into new or old concepts. RECENT FINDINGS Cystic fibrosis carriers have been found to be at increased risk of pancreatitis. Autoimmune pancreatitis may belong to a multiorgan immunoglobulin G4-related autoimmune disease, and the natural history of chronic pancreatitis differs among the etiologies. Diffusion-weighted magnetic resonance imaging improves upon previous methodologies for diagnosing reduced pancreatic exocrine secretion, and fecal elastase-1 has been found to be a poor test for diagnosing pancreatic malabsorption. Visceral hyperalgesia or heightened central pain perception may contribute to pain in chronic pancreatitis. Instruments are evolving to assess quality of life in chronic pancreatitis, and fibrolytic agents have been found to have therapeutic promise. SUMMARY Researchers this past year have further characterized genetic, molecular and clinical aspects of chronic pancreatitis. Advancing the understanding of fibrogenesis, mechanisms of exocrine insufficiency, calcification, and pain and continuing development/modification of diagnostic tests should lead to improved prevention, detection and treatment of the condition. More accurate quantification of outcomes is critical for translating potential therapies from bench to bedside.
