Pancreatitis aguda recurrente secundaria a disfunción del esfínter de oddi: Reporte de caso

La disfunción del esfínter de Oddi (DEO) es una patología poco frecuente que debe ser considerada en el diagnóstico diferencial de pacientes con episodios de dolor biliar o pancreatitis aguda recurrente y antecedente de colecistectomía. Generalmente son pacientes con múltiples consultas, en los cuales la patología ha afectado considerablemente su calidad de vida. El diagnóstico se sustenta en la clínica, los marcadores serológicos y los medios diagnósticos de soporte, que se solicitan según el componente esfinteriano sospechado. El tratamiento con mayor eficacia es la esfinterotomía endoscópica. El uso de prótesis es aceptado, pero discutido. Se presenta el caso de un paciente masculino en la cuarta década de la vida que consultó por múltiples episodios de pancreatitis aguda recurrente con estudios de etiología que sospecharon disfunción del esfínter de Oddi pancreático y quien fue llevado a manejo endoscópico, con mejoría de su cuadro clínico.

Sphincter of Oddi Dysfunction (SOD) is a rare pathology that should be considered in the differential diagnosis of patients with biliary pain episodes or recurrent acute pancreatitis and a background of cholecystectomy. Generally, these are patients with multiple consultations where this pathology has considerably affected their quality of life. Diagnosis is based on clinical findings, serological markers and supporting diagnostic tests requested according to the suspected sphincteric component. The most effective treatment is endoscopic sphincterotomy. The use of prosthesis is accepted but debated. We present the case of a male patient in his forties who consulted for multiple episodes of recurrent acute pancreatitis with etiology studies suspecting dysfunction of the pancreatic sphincter of Oddi and who was taken to endoscopic management with improvement of his clinical picture.

A Case of Acute Cholangitis Due to Opioid-induced Dysfunction of Sphincter of Oddi in the Patient with Breast Cancer

Opioids are known to cause dysfunction of the sphincter of Oddi. However, there are no reports on acute cholangitis due to opioid-induced dysfunction of the sphincter of Oddi. A 75-year-old woman with breast cancer, who had been prescribed oxycodone for lower abdominal pain due to unknown causes for 8 years, suddenly developed hypochondriac pain. We diagnosed the patient as having acute cholangitis and performed endoscopic retrograde pancreatography and technetium hepatobiliary iminodiacetic acid scan. The cause of acute cholangitis was considered to be opioid-induced dysfunction of the sphincter of Oddi. Six and nine days after admission, endoscopic sphincterotomy was performed, after which her upper abdominal pain resolved. Opioids increase biliary pressure and delay bile flow into the duodenum in patients after cholecystectomy. However, the actual clinical outcomes of using opioids for acute cholangitis and pancreatitis remain unknown. Thus, although opioid-induced dysfunction of the sphincter of Oddi is uncommon, it should be assessed in patients who are prescribed opioids.

Understanding the Biliary Dyspepsia / 대한췌담도학회지

Functional dyspepsia is a very common disease and there are two types of dyspepsia. One is functional dyspepsia in the gastrointestinal tract and the other is pancreatobiliary dyspepsia. Biliary dyspepsia is caused by biliary tract disease and can even cause biliary pain. Acalculous biliary pain (ABP) is biliary colic without gallstones, it is caused by functional biliary disorder or structural disorders such as microlithiasis, sludges or parasitic infestation like Clonorchiasis. The endoscopic ultrasonography is helpful tool for differential diagnosis of ABP. Although sphincter of Oddi manometry (SOM) is performed for the confirmative diagnosis of sphincter of Oddi dysfunction (SOD), several non-invasive tests have been studied because of some practical limitations and invasiveness of SOM itself. In fact, the most clinically used easy test to diagnose functional biliary disorder is quantitative hepatobiliary scintigraphy and it can distinguish gallbladder dyskinesia, SOD, or combined type. Initial treatment of functional biliary disorder is adequate dietary control and medication, but if the symptoms worsened or recurred frequently, laparoscopic cholecystectomy could be performed with gallbladder dyskinesia. If SOD is suspected, additional SOM should be considered and endoscopic sphincterotomy (EST) can be done according to the outcome. If the SOM is not available, the patient could be diagnosed by stimulated ultrasound.

Advances on diagnosis and therapy of sphincter of Oddi dysfunction / 中华肝胆外科杂志

Sphincter of Oddi dysfunction (SDO) is the obstruction of ampulla of Vater,resulting from abnormality of contraction of sphincter of Oddi,which causes the reflux of bile and pancreatic juice and promotes a series of pathophysiological changes in cholangiopancreatic system.Because of lack of typical clinical symptoms and specific diagnostic methods,the standards of diagnosis and therapy are still unclear.Recently,new changes happened in this field with the development of endoscopy and large-scale clinical trials.This review summarized the latest advances on sphincter of Oddi dysfunction in recent years.

Advances in Research on Etiology of Recurrent Acute Pancreatitis / 胃肠病学

Some patients with acute pancreatitis (AP)can relapse after initial cure. With the development and maturity of diagnosis and treatment technology,especially the rise of endoscopic technology,the detection rate of AP recurrence (such as bile duct stones,Oddi sphincter dysfunction,pancreas divisum,gene mutation,etc. )is increased. Recurrent acute pancreatitis (RAP)is characterized by various causes,and complex mechanisms. Understanding etiology and positive treatment play a pivotal role in reducing the incidence of RAP. This article reviewed the advances in study on etiology of RAP.

Cólico biliar inducido por morfina / Morphine induced biliary pain: case report

Morphine produces contraction of Oddi’s sphincter, which can be severe and of longer duration in some pathological conditions. This exaggerated response can manifest as a colicky biliary pain, frequently accompanied by a dramatic increase in hepatic enzymes. We report a 32 years old female who consulted in the emergency room for severe low abdominal pain of gynecologic origin, which was completely controlled by morphine. However, she presented a sudden epigastric colicky pain irradiating in the back, which persisted for several hours in spite of the repeated administration of analgesics. Transaminases elevated from previously normal value to over 1,000 U/L, and returned to the normal level without further treatment after several days. Magnetic resonance cholangiography showed normal fine bile duct, without stones. This transient increase in hepatic enzymes was considered as a consequence of high biliary pressure secondary to morphine-induced spastic contraction of Oddi’s sphincter and a consecutive hepatocellular necrosis.

Impact of motilin, neurotensin and nitric oxide synthase on sphincter of Oddi dysfunction / 中华消化内镜杂志

Objective To investigate the impact of motilin(MTL), neurotensin(NT)and nitric oxide synthase(NOS)on Oddi sphincter(SO)motion after cholecystectomy. Methods Oddi sphincter manometry(SOM)was performed on both Guinea pig model group(cholecystectomy)and control group (laparotomy)12 weeks after operation. Sphincter of Oddi dysfunction(SOD)group was determined by receiver operating characteristic(ROC)curve analysis and area under curve(AUC). Protein expression of MTL, NT and NOS in SO was also detected through integral optical density method. Meanwhile,the contents of MTL and NT in patients′ plasma of both SOD group(SO pressure> 40 mmHg)and control group were compared. Results AUC of 0.75 and SO pressure of more than 29.8 mmHg was determined as the standard of SOD group.MTL and NT contents(193.16±29.2 pg/mL and 104.57±19.52 pg/mL,respectively)of the model group(n=10)in plasma were significant higher than those of control group(n=11)(154.24 ± 27.69 pg/mL and 79.65±11.24 pg/mL,respectively),and same trend of MTL and NT protein expression in SO was detected(3 556.71±455.80 and 6 321.74±203.54 of the model group;3 075.92±350.06 and 5 843.57±344.00 of the control group).While NOS protein expression in model group was lower than that of the control group(2 954.21± 173.54 VS 3 314.91± 246.67, P<0.05). In clinical research, the plasma contents of MTL(350.98 ± 24.31 pg/mL VS 319.56 ± 23.54 pg/mL)and NT(102.39 ± 19.56 pg/mL VS 80.45±12.35 pg/mL)in SOD group(n=15)were higher than those of the control group(n=15)(P<0.05). Conclusion MTL and NT contents in plasma and protein expression of MTL, NT and NOS in SO may be related to SOD. MTL and NT examinations may assist diagnosing SOD after cholecystectomy.

Advances in Diagnosis and Treatment of Sphincter of Oddi Dysfunction / 胃肠病学

Sphincter of Oddi dysfunction (SOD)is a functional gastrointestinal disorder manifesting with the main symptoms of abdominal pain,abnormal liver function and recurrent idiopathic acute pancreatitis,which involved the abnormal contraction of sphincter of Oddi. The incidence of SOD has been increasing in recent years. More attention should be paid on SOD for decreasing the misdiagnosis in clinical practice. This article reviewed the recent advances in diagnosis and treatment of SOD.

New Research and Insight on Sphincter of Oddi Dysfunction / 胃肠病学

Sphincter of Oddi dysfunction (SOD) refers to a series of clinical syndromes that occurs because of structural or functional disorders involving the biliary and/or pancreatic sphincters.It remains controversial whether endoscopic sphincter manometry (SOM) or sphincterotomy is needed in patients with type Ⅲ SOD.An important problem is that ERCP (with or without SOM) carries significant risks, especially the post-ERCP pancreatitis.The EPISOD trial has updated our knowledge on type Ⅲ SOD.The latest Rome Ⅳ consensus suggested that the classification term type Ⅲ biliary SOD should be abandoned and a new classification of biliary SOD was proposed;also, manometry and sphincterotomy were not recommended for patients with this type of SOD.The goal of this paper is to review recent literatures and elucidate the selected important questions regarding type Ⅲ SOD.

Sphincter Oddi manometry and endoscopic sphincterotomy in diagnosis and treatment of patients with sphincter of Oddi dysfunction / 中国内镜杂志

Abstact: Objective To investigate the diagnostic value of endoscopic sphineter Oddi manometry (SOM) in patients with recurring abdominal pain and observe the value of endoscopic sphincterotomy (EST) in treatment of patients with sphincter of Oddi dysfunction (SOD).MethodsClinical data of 30 patients with chronic abdominal pain after cholecystectomy who were suspected SOD from 2012 October to 2014 September were collected and retrospectively analyzed. These patients received SOM in ERCP examination and the observation of Oddi sphincter basal pressure, contraction amplitude, frequency and mode of transmission were carried out. The EST were carried out in patients with basal pressure of Oddi sphincter higher than 40.0 mmHg or higher than 30.0 mmHg, and the presence of serum amylase, lipase, ALT, AST, AKP increased more than 2 times of the normal value and (or) of common bile duct, pancreatic duct widening.ResultThe SOM of all the 30 patients were all abnormal. The basal pressure of Oddi sphincter, the contraction amplitude, the contraction frequency and the reverse shrinkage were (36.6 ± 21.1) mmHg, (210.6 ± 25.7) mmHg, (10.1 ± 3.1) times/min and (55.0 ± 8.0)%. All the patients were treated with EST, of which 27 cases (90.0%) received good results.Conclusion SOM is helpful in evaluation of Oddisphincter function, it is of great value in diagnosis of SOD. EST treatment obtained satisfactory effect in patients with elevated basal pressure of Oddi sphincter.

The sphincter of Oddi: from incision to repair / 临床肝胆病杂志

The sphincter of Oddi is a valve that controls the biliopancreatic duct and plays an irreplaceable role in maintaining normal physiological functions of the biliopancreatic duct.However,sphincteroplasty and sphincterotomy may cause varying degrees of damage to the function of the sphincter of Oddi,which may further result in postoperative reflux of duodenal fluids and bacterial contamination in bile and increase the risks of recurrent common bile duct stones,reflux cholangitis,and even cholangiocarcinoma.Therefore,clinical physicians should protect the structure and function of the sphincter of Oddi.Based on our experience,under the premise that the extrahepatic bile duct can be preserved,patients with iatrogenic injury of the sphincter of Oddi can be treated with transduodenal sphincteroplasty to restore the structural integrity of the sphincter of Oddi and reduce biliopancreatic duct complications secondary to loss of function.

Sphincter of Oddi Manometry: Reproducibility of Measurements and Effect of Sphincterotomy in the EPISOD Study

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.

Therapy for patients with bile duct Ⅲ of sphincter of Oddi dysfunction after cholecystectomy / 中华肝胆外科杂志

Objective To study the therapeutic effect of pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet on patients with bile duct Ⅲ of sphincter of Oddi dysfunction (SOD) after cholecystectomy.Methods 72 patients who had a diagnosis consistent with bile duct Ⅲ of SOD seen from February 2010 to February 2013 in our hospital were randomly divided into the control group and the treatment group.Patients in the control group were given pinaverium bromid for 3 months while patients in the treatment group were,in addition to pinaverium bromid,given oryz-aspergillus enzyme and pancreatin tablet.Relief of abdominal pain,abdominal distention and recurrence of the above symptoms after drug withdrawal were studied.Results The scores on abdominal pain in the treatment group before and after treatment were 7.5 ± 1.1 and 3.0 ± 1.6 (P ＜ 0.05) while the scores in the control group were 7.4 ± 1.1 and 5.0 ± 1.4 (P ＜ 0.05),respectively.Alleviation of abdominal pain in the treatment group was superior to the control group (P ＜ 0.05).The scores on abdominal distention in the treatment group before and after treatment were 5.4 ± 0.6 and 1.6 ± 0.5 (P ＜ 0.05) while the scores in the control group were 5.2 ± 0.5 and 4.7 ± 0.8 (P ＞ 0.05),respectively.Alleviation of abdominal distention in the treatment group was superior to the control group (P ＜0.05).The scores of abdominal pain and distention in half year after 3 months' therapy in the treatment group were 3.1 ± 1.7 and 1.7 ± 1.1,respectively,which obviously were lower than the control group (5.4 ± 1.4 and 5.0 ± 0.6,P ＜ 0.05).Conclusions Pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet could effectively alleviate abdominal pain and distention in patients with bile duct Ⅲ of SOD after cholecystectomy and the recurrence rates of symptoms were significantly lower.

Spinal Cord Stimulation for Intractable Visceral Pain Due to Sphincter of Oddi Dysfunction

Sphincter of Oddi dysfunction (SOD) is a syndrome of chronic biliary pain or recurrent pancreatitis due to the functional obstruction of the pancreaticobiliary flow. We report a case of spinal cord stimulation (SCS) for chronic abdominal pain due to SOD. The patient had a history of cholecystectomy and had suffered from chronic right upper quadrant abdominal pain. The patient had been diagnosed as having SOD. The patient was treated with opioid analgesics and nerve blocks, including a splanchnic nerve block. However, two years later, the pain became intractable. We implanted percutaneous SCS at the T5-7 level for this patient. Visual analog scale (VAS) scores for pain and the amount of opioid intake decreased. The patient was tracked for more than six months without significant complications. From our clinical case, SCS is an effective and alternative treatment option for SOD. Further studies and long-term follow-up are necessary to understand the effectiveness and the limitations of SCS on SOD.

Prophylactic pancreatic duct stenting for biliary-type stenosis of Oddi sphincter with difficult cannulation / 中华消化内镜杂志

Objective To evaluate the clinical value and efficacy of prophylactic pancreatic duct stenting for biliary-type stenosis of Oddi sphincter with difficulty cannulation.Methods The present study was a retrospective study of 63 patients with biliary-type stenosis of Oddi sphincter and difficult cannulation.The stent group consisted 30 patients who underwent prophylactic pancreatic duct stenting from February 2010 to February 2011 and the control group included 33 patients who underwent only ERCP without prophylactic pancreatic duct stenting from January 2009 to January 2010.The incidence of postoperative pancreatitis were compared between the two groups.Results The incidence of postoperative pancreatitis of the control group was significantly higher than that of the stent group (P ＜ 0.05).Conclusion For patients with definite diagnosis of biliary-type stenosis of Oddi sphincter and difficult cannulation,prophylactic pancreatic duct stent placement is safe and effective.

Clinical analysis of endoscopic treatment of recurrent idiopathic pancreatitis / 中华胰腺病杂志

Objective To investigate the characteristics of etiology,efficacy of endoscopic management for recurrent idiopathic pancreatitis (RIP).MethodsThe clinical data of 58 cases of RIP diagnosed in our hospital from April 2005 to April 2011 were retrospectively analyzed.All the patients underwent endoscopic retrograde cholangiopancreatography (ERCP),and patients with suspected sphincter of Oddi dysfunction received manometry.According to the clinical and ERCP manifestations,the etiologies of RIP were determined and individualized endoscopic treatment was applied.The patients were followed-up postoperatively about the improvement of abdominal pain and recurrence of RIP.ResuItsFifty-eight patients (29 males,29 females) were suffered from acute pancreatitis from 3 to more than 10 times.The etiologies were as follows:29 cases of biliary microlithiasis,19 case of sphincter of Oddi dysfunction ( 16 cases of pancreatic type,3 cases of mixed type),4 cases of anomalous arrangement of the pancreaticobiliary duct,and 6 cases of normal manifestations at ERCP.Biliary sphincterotomy alone was performed in 33 patients,while both biliary and pancreatic sphincterotomy was performed in 8 patients,and pancreatic sphincterotomy alone was performed in 17 patients,after sphincterotomy,pancreatic stent insertion was performed in 24 patients.The follow-up data was obtained from 41 out of 58 patients,the follow-up period ranged from 3 ～ 67 months ( average 33 months).During this period,9(22.0％ ) patients suffered from RIP,and the treatment efficiency was 78％.ConclusionsBiliary microlithiasis and sphincter of Oddi dysfunction are the main causes of RIP.Drink could induce RIP.ERCP has definite treatment efficacy for RIP.

How to Interpret a Functional or Motility Test: Sphincter of Oddi Manometry

To date, endoscopic manometry is the best method for evaluating the function of the sphincter. Sphincter of Oddi manometry (SOM) remains the gold standard to correctly diagnose the sphincter of Oddi dysfunction (SOD) and stratify therapy. Several dynamic abnormalities relating to the intensity, frequency, and propagation of sphincter contractions have been described. However, their clinical use generally has been abandoned in favor of basal sphincter pressure alone, because this measurement is stable over time, and has stronger interobserver reliablility, reproducibility on repeating testing, and is associated with the responsiveness to therapy. A significant elevated risk of pancreatitis was attributed to the technique. The risk of pancreatitits associated with manometric evaluation of the pancreatic sphincter is markedly reduced when manometry is performed with continous aspiration from the pancreatic duct via one of the 3 catheter lumens. This section reviews indications, conscious sedative drugs, techniques, and the appropriate interpretations of SOM.

Disfunción del esfínter de Oddi y pancreatitis idiopática / Sphincter of Oddi dysfunction (SOD) and idiopatic pancreatitis

The sphincter of Oddi dysfunction is a little known entity that typically occurs in post-cholecystectomy patients with abdominal pain with biliary or pancreatic characteristics. It represents an important cause of idiopathic recurrent acute pancreatitis. Most of the patients referred for sphincter of Oddi dysfunction study have another disease which explain the symptoms, so a careful history and appropriate physical examination often can identify the true source of the pain. The most used grading score is the Milwaukee classification, based on clinical, laboratory, imaging and cholangiographic findings. In the last decade, new and more applicable criteria have been developed, such as Rome III criteria, which do not require functional tests considered complex and not available in non-specialized centers. The sphincter of Oddimanometry is considered the gold standard for the diagnosis of this entity, allowing for the determination of which patients will benefit from endoscopic therapy (sphincterotomy). There are some noninvasive diagnostic tests that have failed to show strong correlation to displace the sphincter of Oddi. The treatment of this condition is mainly based on endoscopic sphincterotomy, with variable success rates depending on the type of dysfunction. This article presents a review of the most important aspects related to the sphincter of Oddi and its relationship with idiopathic recurrent pancreatitis.

La disfunción del esfínter de Oddi es una entidad poco conocida, que típicamente se presenta en pacientes post-colecistectomía con dolor abdominal de tipo “biliar” o “pancreático”. Representa unaimportante causa de pancreatitis aguda recurrente idiopática. La mayoría de los pacientes derivados para estudio de disfunción del esfínter de Oddi corresponden a otra causa o enfermedad que explica los síntomas, por lo que una cuidadosa historia clínica y un adecuado examen físico, a menudo permiten identificar el verdadero origen del cuadro doloroso. La clasificación más utilizada es la de Milwaukee basada en parámetros clínicos, de laboratorio, imagenológicos y colangiográficos. En la última década, se han elaborado criterios de mayor aplicabilidad clínica como los criterios de Roma III, que no requieren de test funcionales considerados complejos y poco disponibles en centros no especializados. La manometría del esfínter de Oddi es considerado el gold standard en el diagnóstico de esta entidad, permitiendo además, establecer quiénes se beneficiarán con la terapia endoscópica (esfinterotomía). Se han desarrollado una serie de otros métodos diagnósticos no invasivos, que no han logrado demostrar una correlación suficientemente sólida para desplazar a la manometría. El tratamiento de esta condición se basa principalmente en la esfinterotomía endoscópica, con una tasa de éxito variable dependiendo del tipo de disfunción. En el presente artículo se revisarán los aspectos más importantes relacionados con la disfunción del esfínter de Oddi y su relación con pancreatitis recurrente idiopática.

Recurrent Acute Pancreatitis Associated with Sphincter of Oddi Dysfunction in a Child / 대한소아소화기영양학회지

Recent studies suggest that sphincter of Oddi dysfunction (SOD) is one of the possible causes of unexplained recurrent acute pancreatitis in children. A 14-year-old boy who had suffered from idiopathic recurrent acute pancreatitis was diagnosed with SOD. Abdominal ultrasonography, computerized tomography, and magnetic resonance cholangiopancreatography revealed no evidence of stone, tumor, or pancreatic ductal anomaly. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincter of Oddi manometry (SOM) revealed elevated basal pressure and tachyoddia consistent with SOD. Hence, an endoscopic pancreatic sphincterotomy was performed. We report a case of recurrent acute pancreatitis associated with SOD in a child. ERCP and SOM may be considered in patients with multiple unexplained attacks of pancreatic pain and negative abdominal imaging.
