Objectives: The sphincter of Oddi(SO) manometry via transpapillary route is performed usually for a period of several minutes. To investigate whether there is a considerable variation in the manometric measurements of SO over a longer period of time, we have performed long-term manometry of SO via transpapillary(n=5) as well as percutaneous(n=7) route. Methods: Transpapillary manometry of SO was carried out by conventional low- compliant continuously perfused techni~que. The location of the manometric catheter was maintained at the same level by observing the video monitor. SO manometry and the duodenal migrating motor complex(MMC) was simuitaneously measured with specially designed catheter via pereutaneous route. Results: The mean recording time was 41 minutes(range 11-72 minutes). The frequency of phasic contractions of SO varied from 0 to 12/min. Throughout the whole recording period, high-frequency contractians(over 8/min) were noted in 14.9 % of the time. In the eases of percutaneous transductal SO manometry, the periods of high-frequency contractions coincided with the phase III of duodenal MMC. The interval between the first high-frequency contractions and the second was 47 minutes. The mean duration of high-frequency contractions was 6 minutes and 4~2 seconds. There as no significant change in the amplitude, basal pressure and contraction sequence among the various periods of frequencies. Conclusions: Long-term continuous recording of SO manometry via transpapillary and percutaneous route showed that the contraction frequency of SO was not constant and tachyoddia appearde periodically. In the interpretation of tachyoddia, it is necessary to consider the period of phase III of the duodenal MMC.

4.How to Interpret a Functional or Motility Test: Sphincter of Oddi Manometry.
Journal of Neurogastroenterology and Motility 2012;18(2):211-217
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.

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.

We evaluated the clinical characteristics of patients with SO dyskinesia(n=16) who were confirmed by ERCP manometry during past 5 years. They were 14 male and 2 female and mean age was 52-year-old(range, 32-75). According to the criteria suggested by Hogan and Geenen, 13 patients were classified into biliary type and 3 patients into pancreatic type. Among the patients with biliary type(n=13), 12 patients fulfilled the criteria for group II dysfunction of SO and 1 patient for group III. Among the patients with pancreatic type(n=3), all fulfilled the criteria for group II. The manometric abnormalities were increased basal pressure(n=4), tachyoddia(n=7), increased retrograde propagation(n=3), tachyoddia and increased retrograde propagation(n=l), and tachyoddia and increased basal pressure(n=l). As treatment, 12 patients received conventional endoscopic sphincterotomy and 3 patients received endoscopic pancreatic sphincterotomy in addition to conventional endoscopic sphincterotomy. Satisfactory results (complete absence or marked reduction of pain) were obtained in 13(87%) out of 15 patients by endoscopic treatment. In conclusion, SO dyskinesia is not so common disease and the detection of patients with SO dyskinesia may increase by frequent application of ERCP manometry.

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.

PURPOSE: Biliary dyskinesia was considered as a wastebasket of quasi-biliary disease which could not be clearly explained under the basis of morphologic pathology. This entity was a source of confusion because of misconception and poor understanding. Recent introduction of biliary manometric technique enlightened some of these disorders. We evaluated the cholangiographic morphology of these disorders to clarify and to characterize the some characteristic findings, subsequently in order to help the diagnosis. MATERIALS AND METHODS: Five cases were confirmed by this technique as sphincter of Oddi dysfunction for last 13 months. All patients were female and age range was 53 to 75 years old. All patients were suffered from intermittent and recurrent biliary type pain. RESULTS: ERCP showed five common findings. The common bile duct was dilated over 12ram in all patients. Different from recurrent pyogenic cholangiohepatitis, intrahepatic ducts were proportionally dilated as extrahepatic ducts, in four patients and they branched normally and ductal wall was smooth. Transient or persistent meniscus sign was observed in four patients. All patients showed delayed emptying of contrast media from the common bile duct into the duodenum. Following IV injection of cholecystokinin, persistent meniscus disappeared and contrast media inflowed into the duodenum. CONCLUSION: Identification of all or some characteristic cholangiographic findings may eliminate a cumbersome and painful biliary manometric test for the diagnosis of sphincter of Oddi dysfunction.

BACKGROUND/AIMS: Pain is one of the most troublesome symptoms of pancreatitis. Transdermal fentanyl patches (TFPs) are long-acting analgesics with a reduced risk of dependency. This prospective study evaluated the effect of TFPs on sphincter of Oddi (SO) motility for the management of pain in pancreatitis. METHODS: SO manometry (SOM) was performed using triple-lumen catheters anterogradely inserted through the percutaneous transhepatic route during cholangioscopy in 16 patients. The basal pressure, amplitude, and frequency of the SO were assessed before and after applying a TFP at 24 hour at doses of 25 and 12.5microgram/hr, respectively. RESULTS: Two of 16 patients receiving a 25microgram/hr. TFP were excluded because of adverse side effects (headache and/or nausea). The mean basal pressure, amplitude, and frequency of SOM did not change significantly in the 25microgram/hr TFP group (n=4 patients). Parameters of SO function also did not significantly change in the 12.5microgram/hr TFP group (n=11 patients). CONCLUSIONS: TFPs below a dose of 25microgram/hr may not affect the motility of the SO. Administration of TFPs at lower dosages seems to be a safe analgesic treatment for the pain control of patients with pancreatitis without affecting the function of the SO.
