Abstract
Background Transpancreatic biliary sphincterotomy (TPBS) is an advanced cannulation method for accessing common bile duct (CBD) in endoscopic retrograde cholangiopancreatography (ERCP). If CBD cannulation is difficult, an endoscopist can open the septum between the pancreatic and biliary duct with a sphincterotome to gain access. Long-term results of this procedure are unclear. We wanted to evaluate the short- and long-term complications of TPBS on patients with native papilla and benign indication for ERCP. Patients and Methods ERCPs performed in Helsinki University Hospital between 2007 and 2013 were reviewed. The study group comprised 143 consecutive patients with TPBS and 140 controls (CG). Data were collected from patient records and a phone survey was performed as a follow-up ≥ 4 years after the index ERCP. Results Post-ERCP pancreatitis (PEP) developed in seven patients (4.9%) in TPBS and one patient (0.7%) in CG (p = 0.067). The rates of other acute complications were similar between the groups. ERCP ended with no access to CBD in four cases (2.8%) in TPBS. The median length of follow-up was 6 years in TPBS and 7 years in CG. During this period, three patients (2.1%) in TPBS and six patients (4.3%) in CG suffered from acute pancreatitis (AP) (p = 0.238). One (0.7%) patient in CG and none in TPBS developed chronic pancreatitis (CP). Abdominal pain was suffered by ten patients (6.9%) in TPBS and twelve patients (8.6%) in CG daily, whereas by six patients (4.2%) in TPBS and twelve patients (8.6%) in CG weekly. Conclusion TPBS is a useful procedure, with acceptable complication rates. No significant difference occurred between the groups when evaluating the short-term or long-term complications with a follow-up period of four to 10 years. Additionally, no significant differences occurred in upper abdominal pain, episodes of AP, or development of CP.

Abstract
OBJECTIVE Functional pancreatic sphincter dysfunction (FPSD), previously characterized as pancreatic sphincter of Oddi dysfunction, is a rarely described cause of pancreatitis. Most studies are reported in adults with alcohol or smoking as confounders, which are uncommon risk factors in children. There are no tests to reliably diagnose FPSD in pediatrics and it is unclear to what degree this disorder contributes to childhood pancreatitis. METHODS We conducted a literature review of the diagnostic and treatment approaches for FPSD, including unique challenges applicable to pediatrics. We identified best practices in the management of children with suspected FPSD and formed a consensus expert opinion. RESULTS In children with acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP), we recommend that other risk factors, specifically obstructive factors, be ruled out before considering FPSD as the underlying etiology. In children with ARP/CP, FPSD may be the etiology behind a persistently dilated pancreatic duct in the absence of an alternative obstructive process. Endoscopic retrograde cholangiopancreatography with sphincterotomy should be considered in a select group of children with ARP/CP when FPSD is highly suspected and other etiologies have been effectively ruled out. The family and patient should be thoroughly counseled regarding the risks and advantages of endoscopic intervention. Endoscopic retrograde cholangiopancreatography for suspected FPSD should be considered with caution in children with ARP/CP when pancreatic ductal dilatation is absent. CONCLUSIONS Our consensus expert guidelines provide a uniform approach to the diagnosis and treatment of pediatric FPSD. Further research is necessary to determine the full contribution of FPSD to pediatric pancreatitis.

Abstract
BACKGROUND AND STUDY AIMS The objective of this study was to clarify the effectiveness of treatment selection for biliary-type sphincter of Oddi dysfunction by severe pain frequency and the risk factors for recurrence including the history of functional gastrointestinal disorder. PATIENTS AND METHODS Thirty-six sphincter of Oddi dysfunction patients who were confirmed endoscopic retrograde cholangiopancreatography enrolled in this study. Endoscopic sphincterotomy was performed for type I and manometry-confirmed type II sphincter of Oddi dysfunction patients with severe pain (⩾2 times/year; endoscopic sphincterotomy group). Others were treated medically (non-endoscopic sphincterotomy group). RESULTS The short-term effectiveness rate of endoscopic sphincterotomy was 91%. The final remission rates of the endoscopic sphincterotomy and non-endoscopic sphincterotomy groups were 86% and 100%, respectively. Symptoms relapsed after endoscopic sphincterotomy in 32% of patients. Patients in the endoscopic sphincterotomy and non-endoscopic sphincterotomy groups had or developed functional dyspepsia in 41% and 14%, irritable bowel syndrome in 5% and 14%, and gastroesophageal reflux disorder in 14% and 0%, respectively. History or new onset of functional dyspepsia was related to recurrence on multivariate analysis. The frequency of occurrence of post-endoscopic retrograde cholangiopancreatography pancreatitis and post-endoscopic retrograde cholangiopancreatography cholangitis was high in both groups. Two new occurrences of bile duct stone cases were observed in each group. CONCLUSION According to the treatment criteria, endoscopic and medical treatment for biliary-type sphincter of Oddi dysfunction has high effectiveness, but recurrences are common. Recurrences may be related to new onset or a history of functional dyspepsia.

Abstract
Patients with recurrent acute pancreatitis (RAP) have few treatment options available to them to manage their symptoms or prevent progression to chronic pancreatitis. At present, endotherapy is typically pursued as a means to achieve symptom remission and reduce rates of recurrence, hospitalization, abdominal pain, narcotic use, and surgical intervention. However, evidence that endotherapy effectively alters the natural history of disease remains limited. This article reviews the recent literature on the efficacy of endoscopic intervention in the treatment RAP with a focus on high-quality prospective randomized controlled studies. Additional studies are needed to corroborate these findings.

Abstract
Recurrent acute pancreatitis (RAP) is a clinically significant problem globally. The etiology remains unclear in approximately 10% to 15% of patients despite a thorough workup. Data on natural history and efficacy of treatments are limited. We aimed to establish criteria for diagnosis, evaluate the causative factors, and arrive at a consensus on the appropriate workup and management of patients with RAP. The organizing committee was formed, and a set of questions was developed based on the current evidence, controversies, and topics that needed further research. After a vetting process, these topics were assigned to a group of experts from around the world with special interest in RAP. Data were presented as part of a workshop on RAP organized as a part of the annual meeting of the America Pancreatic Association. Pretest and Posttest questions were administered, and the responses were tabulated by the current Grades of Recommendation Assessment, Development and Evaluation system. The consensus guidelines were established in the format of a diagnostic algorithm. Several deficiencies were identified with respect to data on etiology, treatment efficacies, and areas that need immediate research.

Abstract
Post-cholecystectomy syndrome and the concept of a causal relationship to sphincter of Oddi dysfunction, despite the controversy, has presented a clinically relevant conflict for decades. Historically surgeons, and now gastroenterologists have expended tremendous efforts towards trying to better understand the dilemma that is confounded by unique patient phenotypes. Areas covered: This review encompasses the literature from a century of experience on the topic of post-cholecystectomy syndrome. Relevant historical and anecdotal experiences are examined in the setting of insights from evaluation of recently available controlled data. Expert commentary: Historical observations and recent data suggest that patients with post-cholecystectomy syndrome can be categorized as follows. Patients with sphincter of Oddi stenosis will most often benefit from treatment with sphincterotomy. Patients with classic biliary pain and some objective evidence of biliary obstruction may have a sphincter of Oddi disorder and should be considered for endoscopic evaluation and therapy. Patients with atypical post-cholecystectomy pain, without any evidence consistent with biliary obstruction, and/or with evidence for another diagnosis or dysfunction should not undergo ERCP.

Abstract
BACKGROUND The role of endoscopic sphincterotomy (ES) in idiopathic recurrent acute pancreatitis (IRAP) is unclear. We hypothesized that ES will alter the natural history of IRAP. METHODS We retrospectively studied the course of 50 IRAP patients from the NAPS2 study from UPMC based on whether they underwent ES or were managed medically. Data included age at first AP, rate of attacks, and history of severe AP. Primary outcomes were any subsequent AP and rate of attacks; secondary outcome was chronic pancreatitis (CP) diagnosis during follow-up. Similar data was abstracted for alcoholic RAP. RESULTS When compared with medically managed IRAP patients (n = 24, 48%), those who underwent ES (n = 26, 52%) had similar rate of attacks/year (median 1.54 vs. 1.41, p = 0.63), but significantly more attacks (median 3 vs. 2, p = 0.04) at baseline. During follow-up (median 7 years), rate of attacks/year decreased significantly, and were similar in both groups (median 0.16 vs. 0, p = ns). Predictors for rate of attacks during follow-up were sex (ratio 0.54 in females, p = 0.045) and rate of attacks at baseline (ratio for doubling 1.2, p = 0.025), but not ES. Alcoholic RAP patients had lower rate of attacks at baseline, but higher risk of subsequent AP (80 vs. 46%, p = 0.021) and rate of attacks/year (median 0.25 vs. 0, p = 0.016) during follow-up. Progression to CP occurred in IRAP and ES, medically managed IRAP, and alcoholic RAP in 27%, 8% and 27% respectively (p = ns). CONCLUSIONS ES, chosen in patients with higher burden of attacks, does not seem to impact the natural history of IRAP.

Abstract
Background/Aims The reproducibility of sphincter of Oddi manometry (SOM) measurements and results of SOM after sphincterotomy has not been studied sufficiently. The aim of our study is to evaluate the reproducibility of SOM and completeness of sphincter ablation. Methods The recently published Evaluating Predictors and Interventions in sphincter of Oddi dysfunction (EPISOD) study included 214 subjects with post-cholecystectomy pain, and fit the criteria of sphincter of Oddi dysfunction type III. They were randomized into 3 arms, irrespective of manometric findings: sham (no sphincterotomy), biliary sphincterotomy, and dual (biliary and pancreatic). Thirty-eight subjects had both biliary and pancreatic manometries performed twice, at baseline and at repeat endoscopic retrograde cholangiopancreatography after 1–11 months. Sham arm was examined to assess the reproducibility of manometry, and the treatment arms to assess whether the sphincterotomies were complete (elevated pressures were normalized). Results Biliary and pancreatic measurements were reproduced in 7/14 (50%) untreated subjects. All 12 patients with initially elevated biliary pressures in biliary and dual sphincterotomy groups normalized after biliary sphincterotomy. However, 2 of 8 subjects with elevated pancreatic pressures in the dual sphincterotomy group remained abnormal after pancreatic sphincterotomy. Paradoxically, normal biliary pressures became abnormal in 1 of 15 subjects after biliary sphincterotomy, and normal pancreatic pressures became abnormal in 5 of 15 patients after biliary sphincterotomy, and in 1 of 9 after pancreatic sphincterotomy. Conclusions Our data suggest that SOM measurements are poorly reproducible, and question whether we could adequately perform pancreatic sphincterotomy.

Abstract
The concept that motor disorders of the gallbladder, cystic duct and sphincter of Oddi can cause painful syndromes is attractive and popular, at least in the USA. However, the results of commonly performed ablative treatments (cholecystectomy and sphincterotomy) are not uniformly good. The predictive value of tests that are often used to diagnose dysfunction (dynamic gallbladder scintigraphy and sphincter manometry) is controversial. Evaluation and management of these patients is made difficult by the fluctuating symptoms and the placebo effect of invasive interventions. A recent stringent study has shown that sphincterotomy is no better than sham treatment in patients with post-cholecystectomy pain and little or no objective abnormalities on investigation, so that the old concept of sphincter of Oddi dysfunction (SOD) type III is discarded. ERCP approaches are no longer appropriate in that context. There is a pressing need for similar prospective studies to provide better guidance for clinicians dealing with these patients. We need to clarify the indications for cholecystectomy in patients with Functional Gallbladder Disorder (FGBD) and the relevance of sphincter dysfunction in patients with some evidence for biliary obstruction (previously SOD type II, now called "Functional Biliary Sphincter Disorder - FBSD") and with idiopathic acute recurrent pancreatitis.

Abstract
IMPORTANCE Abdominal pain after cholecystectomy is common and may be attributed to sphincter of Oddi dysfunction. Management often involves endoscopic retrograde cholangiopancreatography (ERCP) with manometry and sphincterotomy. OBJECTIVE To determine whether endoscopic sphincterotomy reduces pain and whether sphincter manometric pressure is predictive of pain relief. DESIGN, SETTING, AND PATIENTS Multicenter, sham-controlled, randomized trial involving 214 patients with pain after cholecystectomy without significant abnormalities on imaging or laboratory studies, and no prior sphincter treatment or pancreatitis randomly assigned (August 6, 2008-March 23, 2012) to undergo sphincterotomy or sham therapy at 7 referral medical centers. One-year follow-up was blinded. The final follow-up visit was March 21, 2013. INTERVENTIONS After ERCP, patients were randomized 2:1 to sphincterotomy (n = 141) or sham (n = 73) irrespective of manometry findings. Those randomized to sphincterotomy with elevated pancreatic sphincter pressures were randomized again (1:1) to biliary or to both biliary and pancreatic sphincterotomies. Seventy-two were entered into an observational study with conventional ERCP managemeny. MAIN OUTCOMES AND MEASURES Success of treatment was defined as less than 6 days of disability due to pain in the prior 90 days both at months 9 and 12 after randomization, with no narcotic use and no further sphincter intervention. RESULTS Twenty-seven patients (37%; 95% CI, 25.9%-48.1%) in the sham treatment group vs 32 (23%; 95% CI, 15.8%-29.6%) in the sphincterotomy group experienced successful treatment (adjusted risk difference, -15.6%; 95% CI, -28.0% to -3.3%; P = .01). Of the patients with pancreatic sphincter hypertension, 14 (30%; 95% CI, 16.7%-42.9%) who underwent dual sphincterotomy and 10 (20%; 95% CI, 8.7%-30.5%) who underwent biliary sphincterotomy alone experienced successful treatment. Thirty-seven treated patients (26%; 95% CI,19%-34%) and 25 patients (34%; 95% CI, 23%-45%) in the sham group underwent repeat ERCP interventions (P = .22). Manometry results were not associated with the outcome. No clinical subgroups appeared to benefit from sphincterotomy more than others. Pancreatitis occurred in 15 patients (11%) after primary sphincterotomies and in 11 patients (15%) in the sham group. Of the nonrandomized patients in the observational study group, 5 (24%; 95% CI, 6%-42%) who underwent biliary sphincterotomy, 12 (31%; 95% CI, 16%-45%) who underwent dual sphincterotomy, and 2 (17%; 95% CI, 0%-38%) who did not undergo sphincterotomy had successful treatment. CONCLUSIONS AND RELEVANCE In patients with abdominal pain after cholecystectomy undergoing ERCP with manometry, sphincterotomy vs sham did not reduce disability due to pain. These findings do not support ERCP and sphincterotomy for these patients. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00688662.

Abstract
Symptomatic cholelithiasis and functional disorders of the biliary tract present with similar signs and symptoms. The functional disorders of the biliary tract include functional gallbladder disorder, dyskinesia, and the sphincter of Oddi disorders. Although the diagnosis and treatment of symptomatic cholelithiasis are relatively straightforward, the diagnosis and treatment of functional disorders can be much more challenging. Many aspects of the diagnosis and treatment of functional disorders are in need of further study. This article discusses uncomplicated gallstone disease and the functional disorders of the biliary tract to emphasize and update the essential components of diagnosis and management.

Abstract
Endoscopy plays an important role in both the diagnosis and the initial management of recurrent acute pancreatitis, as well as the investigation of refractory disease, but it has known limitations and risks. Sound selective use of these therapies, complemented with other lines of investigation such as genetic testing, can dramatically improve frequency of attacks and associated quality of life. Whether endoscopic therapy can reduce progression to chronic pancreatitis, or reduce the risk of malignancy, is debatable, and remains to be proven.

Abstract
Since its original description by Oddi in 1887, the sphincter of Oddi has been the subject of much study. Furthermore, the clinical syndrome of sphincter of Oddi dysfunction (SOD) and its therapy are controversial areas. Nevertheless, SOD is commonly diagnosed and treated by physicians. This article reviews the epidemiology, clinical manifestations, and current diagnostic and therapeutic modalities of SOD.

Abstract
BACKGROUND & AIMS The role of sphincter of Oddi manometry (SOM) in the management of patients with idiopathic recurrent acute pancreatitis requires clarification. We evaluated the therapeutic effects of endoscopic sphincterotomy in patients with recurrent acute pancreatitis and the prognostic significance of pancreatic sphincter dysfunction (SOD). METHODS We performed a randomized trial of endoscopic retrograde cholangiopancreatography with SOM for patients with idiopathic recurrent acute pancreatitis. Patients with pancreatic SOD (n = 69) were assigned randomly to groups that received only biliary sphincterotomy (BES) or a combination of biliary and pancreatic sphincterotomy (DES); patients who underwent normal SOM (n = 20) were assigned randomly to groups that received BES or a sham surgery. The primary outcome was incidence of recurrent acute pancreatitis during the follow-up period (minimum, 1 year; maximum, 10 years). We also determined the incidence of chronic pancreatitis and analyzed factors associated with recurrence of acute pancreatitis. RESULTS Among the 69 patients with SOD, 48.5% who received BES and 47.2% who received DES had recurrent acute pancreatitis (95% confidence interval, -22.3 to 24.9; P = 1.0). In patients with normal SOM (n = 20), 27.3% of those who received BES and 11.1% of those who received the sham surgery had recurrent acute pancreatitis (95% confidence interval, -49.5 to 17.2; P = .59). Overall, 16.9% of subjects developed chronic pancreatitis during a median follow-up period of 78 months (interquartile range, 35-108 mo). The odds of recurrent acute pancreatitis during follow-up evaluation were significantly greater among patients with SOD than those with normal SOM (unadjusted hazard ratio, 3.5; 95% confidence interval, 1.07-11.4; P < .04), and remained so after adjusting for potential confounders (hazard ratio, 4.3; 95% confidence interval, 1.3-14.5; P < .02). CONCLUSIONS Among patients with pancreatic SOD, DES and BES have similar effects in preventing recurrence of acute pancreatitis. Pancreatic SOD is an independent prognostic factor, identifying patients at higher risk for recurrent acute pancreatitis. CLINICAL TRIALS REGISTRATION Clinicaltrials.gov (NCT01583517).

Abstract
PURPOSE OF REVIEW To summarize the indications, success rates and complications associated with endoscopic sphincterotomy and endoscopic balloon dilation (EBD). RECENT FINDINGS Pancreatic and/or biliary sphincterotomies are essential components of most current therapeutic endoscopic retrograde cholangiopancreatography (ERCP). A current large body of evidence has established biliary sphincterotomy as effective in extraction of bile duct stones. The most common complications of biliary sphincterotomy are post-ERCP pancreatitis, as well as acute or delayed hemorrhage, the risks for which can be stratified according to well described patient and procedure related factors. Evidence is accumulating that pancreatic sphincterotomy is useful in at least some settings for treatment of sphincter of Oddi dysfunction, chronic pancreatitis, and pancreas divisum. EBD provides an adjunct or an alternative to biliary sphincterotomy for extraction of stones from the bile duct when routine biliary sphincterotomy is inadequate or risk excessive. SUMMARY Sphincterotomy and EBD are useful in managing a variety of pancreatobiliary conditions. Attention to risks of these procedures is essential for their efficacy and safety.

Abstract
AIM: To report the results of a medical management of sphincter of oddi dysfunction (SOD) after an intermediate follow-up period.
METHODS: A total of 59 patients with SOD (2 men and 57 women, mean age 51 years old) were included in this prospective study. After medical treatment for one year, the patients were clinically re-evaluated after an average period of 30 mo.
RESULTS: The distribution of the patients according to the Milwaukee’s classification was the following: 11 patients were type 1, 34 were type 2 and 14 were type 3. Fourteen patients underwent an endoscopic sphincterotomy (ES) after one year of medical treatment. The median intermediate follow-up period was 29.8 ± 3 mo (3-72 mo). The initial effectiveness of the medical treatment was complete, partial and poor among 50.8%, 13.5% and 35%, respectively, of the patients. At the end of the follow-up period, 37 patients (62.7%) showed more than 50% improvement. The rate of improvement in patients who required ES was not significantly different compared with the patients treated conservatively (64.2% vs 62.2%, respectively).
CONCLUSION: Our study confirms that conservative medical treatment could be an alternative to endoscopic sphincterotomy because, after an intermediate follow-up period, the two treatments show the same success rates.

Abstract
Given the significant risk of pancreatitis and the advent of high-fidelity diagnostic techniques, ERCP is now reserved as a therapeutic procedure for those with pancreatic disease. Early ERCP benefits those with gallstone pancreatitis who present with or develop cholangitis or biliary obstruction. Among those with idiopathic pancreatitis, ERCP may be used to confirm and treat SOD, microlithiasis, and structural anomalies, including pancreas divisum. Pancreatic endotherapy is a consideration to decrease pain in those with pancreatic duct obstruction, although surgical decompression may be more durable, particularly in those with severe disease. Pancreatic duct leaks may respond to endoscopic drainage, but optimal therapy is achieved if a bridging stent can be placed. Finally, using a wire-guided technique and pancreatic duct stents in high-risk patients, particularly in cases of suspected SOD, may minimize the risk of post-ERCP pancreatitis.

Abstract
This study investigated the changes in echogenicity, as measured by endoscopic ultrasound, and the surface area of the papilla of Vater (PV) and their relationship with postoperative symptoms in a group of 80 patients with symptomatic gallstones before and at 3 and 6 months after cholecystectomy. After cholecystectomy, 50 patients experienced early atypical symptoms characteristic of postcholecystectomy syndrome (PCS) and 30 patients were asymptomatic. The surface area of the PV was larger than normal prior to surgery and increased after surgery. The healthy PV is isoechogenic, but 48% of all patients were anisoechogenic preoperatively, increasing to 61% at 3 months after surgery, and decreasing to 25% at 6 months postsurgery. There was no significant difference between the two patient groups, suggesting that the changes observed in the PV do not explain the presence of the atypical symptoms of PCS.

Abstract
AIM To evaluate the reliability of an instrument that measures disability arising from episodic abdominal pain in patients with suspected sphincter of Oddi dysfunction (SOD). METHODS Although several treatments have been utilized to reduce pain and associated disability, measurement tools have not been developed to reliably track outcomes. Two pilot studies were conducted to assess test-retest reliability of a newly developed instrument, the recurrent abdominal pain intensity and disability (RAPID) instrument. The RAPID score is a 90-d summation of days where productivity for various daily activities is reduced as a result of abdominal pain episodes, and is modeled after the migraine disability assessment instrument used to measure headache-related disability. RAPID was administered by telephone on 2 consecutive occasions in 2 consenting populations with suspected SOD: a pre-sphincterotomy population (Pilot I, n = 55) and a post-sphincterotomy population (Pilot II, n = 70). RESULTS The average RAPID scores for Pilots I and II were: 82 d (median: 81.5 d, SD: 64 d) and 48 d (median: 0 d, SD: 91 d), respectively. The concordance between the 2 assessments for both populations was very good: 0.81 for the pre-sphincterotomy population and 0.95 for the post-sphincterotomy population. CONCLUSION The described pilot studies suggest that RAPID is a reliable instrument for measuring disability resulting from abdominal pain in suspected SOD patients.

Abstract
Sphincter of Oddi dysfunction (SOD) is a term used to describe a group of heterogenous pain syndromes caused by abnormalities in sphincter contractility. Biliary and pancreatic SOD are each sub-classified as type I, II or III, according to the Milwaukee classification. SOD appears to carry an increased risk of acute pancreatitis as well as rates of post ERCP pancreatitis of over 30%. Various mechanisms have been postulated but the exact role of SOD in the pathophysiology of acute pancreatitis is unknown. There is also an association between SOD and chronic pancreatitis but it is still unclear if this is a cause or effect relationship. Management of SOD is aimed at sphincter ablation, usually by endoscopic sphincterotomy (ES). Patients with type I SOD will benefit from ES in 55%-95% of cases. Sphincter of Oddi manometry is not necessary before ES in type I SOD. For patients with types II and III the benefit of ES is lower. These patients should be more thoroughly evaluated before performing ES. Some researchers have found that manometry and ablation of both the biliary and pancreatic sphincters is required to adequately assess and treat SOD. In pancreatic SOD up to 88% of patients will benefit from sphincterotomy. Therefore, there have been calls from some quarters for the current classification system to be scrapped in favour of an overall system encompassing both biliary and pancreatic types. Future work should be aimed at understanding the mechanisms underlying the relationship between SOD and pancreatitis and identifying patient factors that will help predict benefit from endoscopic therapy.

Abstract
Although there are numerous causes of acute pancreatitis, an etiology cannot always be found. Two potential etiologies, microlithiasis and sphincter of Oddi dysfunction, are discussed in this review. Gallbladder microlithiasis, missed on transcutaneous ultrasound, is reported as the cause of idiopathic acute pancreatitis in a wide frequency range of 6%-80%. The best diagnostic technique for gallbladder microlithiasis is endoscopic ultrasound although biliary crystal analysis and empiric cholecystectomy remain as reasonable options. In contrast, in patients who are post-cholecystectomy, bile duct microlithiasis does not appear to have a role in the pathogenesis of acute pancreatitis. Sphincter of Oddi dysfunction is present in 30%-65% of patients with idiopathic acute recurrent pancreatitis in whom other diagnoses have been excluded. It is unclear if this sphincter dysfunction was the original etiology of the first episode of pancreatitis although it appears to have a causative role in recurring episodes since sphincter ablation decreases the frequency of recurrent attacks. Unfortunately, this conclusion is primarily based on small retrospective case series; larger prospective studies of the outcome of pancreatic sphincterotomy for SOD-associated acute pancreatitis are sorely needed. Another problem with this diagnosis and its treatment is the concern over potential procedure related complications from endoscopic retrograde cholangiopancreatography (ERCP), manometry and pancreatic sphincterotomy. For these reasons, patients should have recurrent acute pancreatitis, not a single episode, and have a careful informed consent before assessment of the sphincter of Oddi is undertaken.

Abstract
Acute recurrent pancreatitis is a clinical entity largely associated with pancreatic ductal obstruction. This latter includes congenital variants, of which pancreas divisum is the most frequent but also controversial, chronic pancreatitis, tumors of the pancreaticobiliary junction and sphincter of Oddi dysfunction. This review summarizes current knowledge about diagnostic work-up and therapy of these conditions.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a largely diagnostic to a largely therapeutic modality. Cross-sectional imaging, such as computed tomography (CT) and magnetic resonance imaging (MRI), and less invasive endoscopy, especially endoscopic ultrasound (EUS), have largely taken over from ERCP for diagnosis. However, ERCP remains the “first line” therapeutic tool in the management of mechanical causes of acute recurrent pancreatitis, including bile duct stones (choledocholithiasis), ampullary masses (benign and malignant), congenital variants of biliary and pancreatic anatomy (e.g. pancreas divisum, choledochoceles), sphincter of Oddi dysfunction (SOD), pancreatic stones and strictures, and parasitic disorders involving the biliary tree and/or pancreatic duct (e.g Ascariasis, Clonorchiasis).

Abstract
AIM Endoscopic sphincterotomy is an efficient means of treating sphincter of Oddi dysfunction (SOD), but it is associated with a morbidity rate of 20%. The aim of this study was to assess how frequently endoscopic sphincterotomy was performed to treat SOD in a group of patients with a 1-year history of medical management. METHODS A total of 59 patients, who had been cholecystectomized 9.3 years previously on average, were included in this study and they all underwent biliary scintigraphy. Medical treatment was prescribed for 1 year. Endoscopic sphincterotomy was proposed for patients whose medical treatment had been unsuccessful. RESULTS Eleven patients were rated group 1 on the Milwaukee classification scale, 34 group 2 and 14 group 3. The hile-duodenum transit time (HDTT) was lengthened in 32 patients. The medical treatment was efficient or fairly efficient in 45% of the group 1 patients, 67% of the group 2 patients, and 71.4% of the group 3 patients (P=0.29). Only 14 patients out of the 21 whose medical treatment was unsuccessful agreed to undergo endoscopic sphincterotomy. HDTT was lengthened in 11 of the 14 patients undergoing endoscopic sphincterotomy and in 21 of the 45 non-endoscopic sphincterotomy patients (P=0.03). Twelve of the 14 patients who underwent endoscopic sphincterotomy were cured. CONCLUSION In this prospective series of patients with a 1-year history of medical management, only 23% of the patients with suspected SOD underwent endoscopic sphincterotomy although 54% had an abnormally long HDTT.

Abstract
BACKGROUND Most of the focus on patients with Sphincter of Oddi dysfunction (SOD) has centered on endoscopic management, and thus little is known about quality of life in these patients. AIMS We sought to determine what health-related quality of life components are troublesome to patients with SOD and compare to patients with recurrent pancreatitis. METHODS Using the Brief Symptom Inventory and the SF-12 version 1, as well as proprietary questionnaires, we measured health-related quality of life in patients with biliary SOD and patients with recurrent idiopathic pancreatitis who underwent sphincter of Oddi manometry. RESULTS Both groups had significantly worse quality of life than nonpatients and both groups somatized. Abuse histories were surprisingly common and similar between both groups. CONCLUSIONS Health-related quality of life is impaired and abuse histories are common in SOD patients, and similar to patients with recurrent idiopathic pancreatitis. Whether these characteristics are predictors of healthcare seeking remains to be determined.

Abstract
BACKGROUND There are few data on combined pancreatic and biliary sphincterotomy for sphincter of Oddi dysfunction (SOD), especially regarding clinical features that might predict outcomes. We sought to examine the relative importance of various clinical features and the presence or absence of objective biliary abnormalities in determining responses to endoscopic therapy. METHODS A cohort of consecutive patients with suspected SOD was treated with biliary sphincterotomy, with additional pancreatic sphincterotomy at initial or subsequent endoscopic retrograde cholangiopancreatography if there was abnormal pancreatic manometry in conjunction with pain refractory to biliary sphincterotomy, continuous pain, or a history of amylase elevation. Repeat intervention was offered until response was achieved or complete ablation of all treated sphincters was achieved. Response was assessed by patients using a 5-point Likert scale, and multivariate logistic regression analysis used to identify predictors of response. RESULTS Of 121 patients, 112 (92%) were female, 105 (87%) postcholecystectomy, and by modified Milwaukee biliary classification 18 (15%) were type I, 53 (44%) type II, and 50 (41%) type III. All patients underwent biliary sphincterotomy and 49 (40%) pancreatic sphincterotomy. Good or excellent response at final follow-up was reported by 83 (69%) of 121 patients, including 37 (61%) of 61 patients requiring repeated intervention. Response was not significantly different between biliary types I, II, and III. Patient characteristics (with adjusted odds ratios) that were significant predictors of poor response were normal pancreatic manometry (4.6), delayed gastric emptying (6.0), daily opioid use (4.0), and age <40 (2.7). Abnormal liver function tests or dilated bile duct were not significant. CONCLUSIONS For the treatment of SOD incorporating pancreatic and biliary sphincterotomy, patient characteristics and pancreatic sphincter manometry may be more important predictors of outcome than the traditional classification based on liver chemistries and bile duct dilation.

Abstract
BACKGROUND Accepted techniques for pancreatic sphincterotomy include use of a needle knife or a pull sphincterotome to ablate the sphincter. There are no prospective studies comparing outcomes between both techniques. AIM Compare post-ERCP pancreatitis rates among high-risk patients undergoing pancreatic sphincterotomy with the pull-sphincterotome versus needle-knife technique. STUDY DESIGN Prospective, randomized trial. METHODS Patients diagnosed with pancreatic sphincter hypertension at sphincter of Oddi manometry were randomized to undergo pancreatic sphincterotomy with a pull sphincterotome (followed by pancreatic stenting) or a needle knife over a pancreatic stent. MAIN OUTCOME MEASUREMENTS To compare post-ERCP pancreatitis rates between the pull-sphincterotome and needle-knife groups. RESULTS Forty-eight patients were randomized. Patient demographics and the incidence of patient and procedure risk factors for pancreatitis were similar in both treatment groups. The trial was stopped early after an interim analysis showed that post-ERCP pancreatitis was significantly higher among patients undergoing sphincterotomy with a pull sphincterotome than a needle knife (7/24 = 29% [95% CI 13-51] vs 0/24 = 0% [95% CI 0-12]; P = .01). No other complications were encountered. At a mean follow-up of 12 months (range 6-18 months), 60% of patients had complete symptom relief, 15% partial symptom relief, and 25% recurrent symptoms. Reintervention rates and clinical outcomes were not significantly different between the 2 groups. LIMITATIONS Short duration of follow-up. CONCLUSIONS Pancreatic sphincterotomy is safer in high-risk patients when performed with a needle knife over a pancreatic stent.

Abstract
BACKGROUND Data on sphincter of Oddi dysfunction (SOD) in children are scant. Most children diagnosed with SOD are treated by biliary sphincterotomy with suboptimal results. The efficacy and safety of pancreatic and dual sphincterotomy in children with SOD has not been previously reported. OBJECTIVE To evaluate the efficacy and safety of pancreatic and dual sphincterotomy in children with SOD. MATERIALS AND METHODS Prospective evaluation of all children who underwent endoscopic retrograde cholangiopancreatogram (ERCP) with sphincter of Oddi manometry for evaluation of suspected SOD over a 3-year period. Children diagnosed with SOD underwent pancreatic or dual sphincterotomy with prophylactic pancreatic stenting. RESULTS SOD was diagnosed by sphincter of Oddi manometry in 6 of 11 children who underwent ERCP for suspected SOD. Of the 6 children (mean age, 11 years; range, 5-16; 4 girls) with SOD, 3 presented with recurrent pancreatitis and 3 with postcholecystectomy pain. Pancreatic sphincter hypertension was noted in all 6 patients; concomitant biliary sphincter hypertension was noted in 3 patients with postcholecystectomy pain. Patients with recurrent pancreatitis underwent pancreatic sphincterotomy and those with postcholecystectomy pain underwent dual sphincterotomy. Prophylactic pancreatic stents were placed in all patients. One girl experienced mild post-ERCP pancreatitis. At a mean follow-up of 583 days (range, 325-1445), 4 patients were asymptomatic, 1 experienced partial symptom relief and 1 had recurrent symptoms. CONCLUSIONS As in adults, pancreatic and dual sphincterotomy, in expert hands, is effective and safe in a subgroup of children with SOD. Prospective, randomized trials with larger number of patients are required to validate the efficacy of endotherapy in children with SOD.

Abstract
The functional disorder of the gallbladder (GB) is a motility disorder caused initially either by metabolic abnormalities or by a primary motility alteration. The functional disorders of the sphincter of Oddi (SO) encompass motor abnormalities of either the biliary or the pancreatic SO. Dysfunction of the GB and/or biliary SO produce similar patterns of pain. The pain caused by a dysfunction of the pancreatic SO can be similar to that of acute pancreatitis. The symptom-based diagnostic criteria of motility dysfunction of the GB and biliary SO are episodes of moderate to severe steady pain located in the epigastrium and right upper abdominal quadrant that last at least 30 minutes. GB motility disorder is suspected after gallstones and other structural abnormalities have been excluded. This diagnosis should then be confirmed by a decreased GB ejection fraction induced by cholecystokinin at cholescintigraphy and after disappearance of the recurrent biliary pain after cholecystectomy. Symptoms of biliary SO dysfunction may be accompanied by features of transient biliary obstruction, and those of pancreatic SO dysfunction are associated with elevation of pancreatic enzymes and even pancreatitis. Biliary-type SO dysfunction is more frequently recognized in postcholecystectomy patients. SO manometry is valuable to select patients with sphincter dysfunction; however, because of the high incidence of complications, these patients should be referred to an expert unit for such assessment. Thus invasive tests should be performed only in the presence of compelling clinical evidence and after noninvasive testing has yielded negative findings. The committee recommends that division of the biliary or pancreatic sphincters only be considered when the patient has severe symptoms, meets the required criteria, and other diagnoses are excluded.

Abstract
BACKGROUND A rare, late complication of endoscopic biliary sphincterotomy is the occurrence of short strictures extending from the papillary orifice to the distal parts of the extraduodenal common bile duct. METHODS We evaluated the efficacy of the sequential insertion of multiple stents in the treatment of endoscopic biliary sphincterotomy associated common bile duct strictures. The design of the study is a prospective, single-arm observational study at a university-affiliated teaching hospital of 20 patients with distal common bile duct strictures because of choledocholithiasis-related endoscopic biliary sphincterotomy. Endoscopic treatment consisted of the sequential insertion of an increasing number of plastic stents with ever-larger diameters in 3-month follow-up intervals until stricture resolution. The primary outcome of the study was the rate of resolution of the stricture. The parameters measured were the duration of placement of stents, the maximum diameter, the total number of stents, and the total number of endoscopic sessions required for dilation of the strictures. RESULTS After a median of 9.0 months of stent placement (range 3-22 months) and a median of 20F maximum stent diameter (range 10F-30F), 18 patients (90%) remained stent-free for a median of 14.5 months (range 6-38 months). Two patients (10%) had stricture recurrences at 10 and 24 months. Multivariate regression analysis demonstrated that the time elapsed after endoscopic biliary sphincterotomy was significantly associated with the stent-placement time (however, significance was removed by correction for multiple testing) and the number of ERCPs required for dilation. The initial common bile duct size was significantly associated with the total stent number and diameter needed for stricture resolution (however, significance was removed by correction for multiple testing). Limitations are the low case number and the single-arm, noncontrolled study design. CONCLUSIONS Sequential insertion of an increasing number of biliary stents affords effective treatment of the distal biliary strictures that develop as a late complication of endoscopic biliary sphincterotomy.

Abstract
AIM: The role of the sphincter of Oddi (SO) in ethanol (ETOH)-induced pancreatitis is controversial. Our aim was to characterise the effect of ETOH on basal and stimulated SO motility.
METHODS: SOs removed from white rabbits were placed in an organ bath (Krebs solution, pH7.4, 37 °C). The effects of 2 mL/L, 4 mL/L, 6 mL/L and 8 mL/L of ETOH on the contractile responses of the sphincter were determined. SOs were stimulated with either 0.1 μmol/L carbachol, 1 μmol/L erythromycin or 0.1 μmol/L cholecystokinin (CCK).
RESULTS: ETOH at a dose of 4 mL/L significantly decreased the baseline contractile amplitude from 11.98 ± 0.05 mN to 11.19 ± 0.07 mN. However, no significant changes in the contractile frequency were observed. ETOH (0.6%) significantly decreased both the baseline amplitude and the frequency compared to the control group (10.50 ± 0.01 mN, 12.13 ± 0.10 mN and 3.53 ± 0.13 c/min, 5.5 ± 0.13 cycles(c)/min, respectively). Moreover, 0.8% of ETOH resulted in complete relaxation of the SO. Carbachol (0.1 μmol/L) or erythromycin (1 μmol/L) stimulated the baseline amplitudes (by 82% and 75%, respectively) and the contractile frequencies (by 150% and 106%, respectively). In the carbachol or erythromycin-stimulated groups 2-6 mL/L of ETOH significantly inhibited both the amplitude and the frequency. Interestingly, a 4-5 min administration of 6 mL/L ETOH suddenly and completely relaxed the SO. CCK (0.1 μmol/L) stimulated the baseline amplitude from 12.37 ± 0.05 mN to 27.40 ± 1.82 mN within 1.60 ± 0.24 min. After this peak, the amplitude decreased to 17.17 ± 0.22 mN and remained constant during the experiment. The frequency peaked at 12.8 ± 0.2 c/min, after which the constant frequency was 9.43 ± 0.24 c/min throughout the rest of the experiment. ETOH at a dose of 4 mL/L significantly decreased the amplitude from 16.13 ± 0.23 mN to 14.93 ± 0.19 mN. However, no significant changes in the contractile frequency were observed. ETOH at a dose of 6 mL/L inhibited both the amplitudes and the frequencies in the CCK-stimulated group, while 8 mL/L of ETOH completely relaxed the SO.
CONCLUSION: ETOH strongly inhibits the basal, carbachol, erythromycin, and CCK-stimulated rabbit SO motility. Therefore, it is possible that during alcohol-intake the relaxed SO opens the way for pancreatic fluid to flow out into the duodenum in rabbits. This relaxation of the SO may protect the pancreas against alcohol-induced damage.
