BACKGROUND Choledochoduodenal fistula is an uncommon complication secondary to peptic ulcer disease. Determining this diagnosis is challenging especially when confronted with unspecific physical and radiological findings. CASE REPORT Here we report a case of a 29-year-old Ethiopian female who presented to Geitaoui University Hospital in Beirut, Lebanon with epigastric pain and was diagnosed to have of choledochoduodenal fistula. CONCLUSIONS Choledochoduodenal fistula is a rare complication of duodenal ulcer and this case report may help clinicians to identify suspected cases of this entity with similar presentations.

Clinically, acupuncture affects the motility of the extrahepatic biliary tract, but the underlining mechanisms are still unknown. We applied manual acupuncture (MA) and electrical acupuncture (EA) separately at acupoints Tianshu (ST25), Qimen (LR14), Yanglingquan (GB34), and Yidan (CO11) in forty guinea pigs (4 groups) with or without atropinization under anesthesia while Sphincter of Oddi (SO) myoelectric activities and gallbladder pressure were monitored. In both MA and EA groups, stimulation at ST25 or LR14 significantly increased the frequency and amplitude of SO myoelectrical activities and simultaneously decreased the gallbladder pressure as compared to the pre-MA and pre-EA (P < 0.05). On the contrary, stimulation at GB34 or CO11 significantly decreased SO myoelectricity and increased the gallbladder pressure (P < 0.05). Pretreatment with atropine could abolish the effect of stimulation at acupoints ST25, GB34 and LR14 (P > 0.05), although significant myoelectricity increases were still inducible with MA or EA stimulation at CO11 (P < 0.05). In summary, acupuncture has bi-directional effects to gallbladder pressure and SO function, which probably due to autonomic reflex and somatovisceral interactions.

Local and systemic reactions to implanted metallic devices, particularly to those containing nickel, are well documented. Metal ions are released due to exposure of the metal to blood, proteins, other body fluids, and sheer mechanical stress. Metal ions then complex with native proteins and become antigens, which can elicit hypersensitivity reactions. Another case report depicts a specific allergic complication (early stent occlusion) related to metallic biliary stent implantation. We present a case of allergic symptoms, associated with eating, in a patient who developed nickel sensitivity after biliary metal stent placement confirmed by allergic skin testing to the same metallic biliary stent placed one year earlier. Symptoms resolved following partial removal of the non-epithelialized portion of the biliary stent.

Pancreatic cancer and cholangiocarcinoma are the most common causes of malignant biliary obstruction. They are diseases of increasing incidence and unfavorable prognosis. Only patients with localized disease indicated for surgery have a chance of long-term survival. These patients represent less than 20 % of all patients, despite the progress in our diagnostic abilities.Locally advanced and metastatic tumors are treated with palliative chemotherapy or chemoradiotherapy; the results of such treatments are unsatisfactory. The average survival of patients with unresectable disease is 6 months and only 5-10 % of patients survive 5 years.Biliary drainage is an integral part of palliative treatment. Endoscopically or percutaneosly placed stents improve quality of life, decrease cholestasis and pruritus, but do not significantly improve survival. Biliary stents get occluded over time, possibly resulting in acute cholangitis and require repeated replacement.Photodynamic therapy and radiofrequency ablation, locally active endoscopic methods, have been increasingly used in recent years in palliative treatment of patients with malignant biliary obstruction. In photodynamic therapy, photosensitizer accumulates in tumor tissue and is activated 48 hours later by light of a specific wave length. Application of low voltage high frequency current during radiofrequency ablation results in tissue destruction by heat. Local ablation techniques can have a significant impact in a large group of patients with malignant biliary obstruction, leading to improved prognosis, quality of life and stent patency.

INTRODUCTION: Surgically altered anatomy complicates endoscopic procedures of the pancreaticobiliary tree. Biliary strictures have been managed using percutaneous transhepatic techniques. MATERIALS AND METHODS: In recent years device-assisted enteroscopy (e.g., double balloon enteroscope [DBE]) has been used to gain access to the common bile duct. The length of the scope and its narrow, 2.8-mm working channel limit the use of standard endoscopic retrograde cholangiopancreatography (ERCP) devices. Therefore, shorter enteroscopes for ERCP have been developed. A fully covered self-expandable metallic stent (fcSEMS) cannot be used through the narrow channel. In conventional anatomy, benign biliary strictures have been treated using fcSEMS, requiring fewer endoscopies compared with multiple plastic stenting. RESULTS: Here we report the first case of fcSEMS deployment through the working channel of a novel, long DBE with a 3.2-mm working channel, and 2 cases with the conventional narrow-channel DBE, using the rendezvous technique, with fcSEMS insertion on a wire running along the enteroscope. CONCLUSIONS: These new techniques, here used on benign biliary strictures, are described in detail.

OBJECTIVES: The diagnostic role of endoscopic ultrasound (EUS) in children has only recently been demonstrated, and that also to a lesser extent than in adults. Data on the technique's therapeutic indications remain scarce. We therefore sought to evaluate diagnostic and interventional EUS indications, safety, and impact in children with pancreaticobiliary disorders. METHODS: We retrospectively reviewed our single pediatric center records, covering a 14-year period. RESULTS: From January 2000 to January 2014, 52 EUS procedures were performed in 48 children (mean age: 12 years; range: 2-17 years) with pancreaticobiliary disorders for the following indications: suspected biliary obstruction (nâ=â20/52), acute/chronic pancreatitis (nâ=â20), pancreatic mass (nâ=â3), pancreatic trauma (nâ=â7), and ampullary adenoma (nâ=â2). EUS was found to have a positive impact in 51 of 52 procedures, enabling us to avoid endoscopic retrograde cholangiopancreatography (ERCP) (nâ=â13 biliary; nâ=â6 pancreatic), focusing instead on endotherapy (nâ=â7 biliary; nâ=â14 pancreatic) or reorienting therapy toward surgery (nâ=â7). EUS-guided fine-needle aspiration was carried out on 12 patients for pancreatic tumor (nâ=â4), pancreatic cyst fluid analysis (nâ=â4), autoimmune pancreatitis (nâ=â2), and suspicion of biliary tumor (nâ=â2). A total of 13 therapeutic EUS procedures (11 children) were conducted, including 9 combined EUS-ERCP procedures (7 children, mean age: 8 years, range: 4-11 years), 3 EUS-guided pseudocyst drainage (2 children), and 1 EUS-guided transgastric biliary drainage. CONCLUSIONS: Our study reports on a large pediatric EUS series for diagnostic and therapeutic pancreaticobiliary disorders, demonstrating the impact of diagnostic EUS and affording insights into novel EUS and combined EUS-ERCP therapeutic applications. We suggest considering EUS as a diagnostic and therapeutic tool in the management of pediatric pancreaticobiliary diseases.

BACKGROUND AND STUDY AIMS: The use of covered self-expandable metallic stents (cSEMS) in benign biliary indications is evolving. The aim of the study was to assess the safety and feasibility of cSEMS compared with multiple plastic stents in the treatment of benign biliary stricture (BBS) caused by chronic pancreatitis. PATIENTS AND METHODS: This was a prospective, multicenter, randomized study of 60 patients with BBS caused by chronic pancreatitis. All patients received an initial plastic stent before randomization. At randomization, the stent was replaced either with a single cSEMS or three plastic stents. After 3 months, the position of the cSEMS was checked or another three plastic stents were added. At 6 months after randomization, all stents were removed. Clinical follow-up including abdominal ultrasound and laboratory tests were performed at 6 months and 2 years after stent removal. RESULTS: Two patients dropped out of the cSEMS group before stent removal. In April 2014, the median follow-up was 40 months (range 1â-â66 months). The 2-year, stricture-free success rate was 90â% (95â% confidence interval [CI] 72â%â-â97â%) in the plastic stent group and 92â% (95â%CI 70â%â-â98â%) in the cSEMS group (Pâ=â0.405). There was one late recurrence in the plastic stent group 50 months after stent removal. Stent migration occurred three times (10â%) in the plastic stent group and twice in the cSEMS group (7â%; Pâ=â1.000). CONCLUSION: A 6-month treatment with either six 10-Fr plastic stents or with one 10-mm cSEMS produced good long-term relief of biliary stricture caused by chronic pancreatitis.Study registered at ClinicalTrials.gov (NCT01085747).

Sphincter of Oddi disorder (SOD) is a part of functional gastrointestinal disorder which is a non-calculous obstructive disorder. This disease is more common in middle-aged women with a prevalence of around 1.5% but in patients with post-cholecystectomy syndrome (PCS) the prevalence rate is markedly higher (9-55%). This high variability maybe attributed to lack of uniformity in patient selection criteria, definition of SOD, and the diagnostic method used. Abdominal pain is the most common symptom occurring due to obstruction at the SO leading to ductal hypertension, ischemia from spastic contraction and hypersensitivity of papilla. Clinical diagnosis of SOD can be achieved by Rome III criteria. Various classifications are used (Milwaukee billiary and modified Milwaukee group classification) for billiary and pancreatic SOD. Not a single non-invasive method is diagnostic. Sphincter of Oddimanometry (SOM) is the gold standard method for evaluating and deciding the management of an SOD patient. The symptomatic relief rate varies from 55% to 95%, so risk-benefit ratio should be evaluated with each patient.

AIM: To investigate the causes and intraoperative detection of endoscopic retrograde cholangiopancreatography (ERCP)-related perforations to support immediate or early diagnosis. METHODS: Consecutive patients who underwent ERCP procedures at our hospital between January 2008 and June 2013 were retrospectively enrolled in the study (n = 2674). All procedures had been carried out using digital fluoroscopic assistance with the patient under conscious sedation. For patients showing alterations in the gastrointestinal anatomy, a short-type double balloon enteroscope had been applied. Cases of perforation had been identified by the presence of air in or leakage of contrast medium into the retroperitoneal space, or upon endoscopic detection of an abdominal cavity related to the perforated lumen. For patients with ERCP-related perforations, the data on medical history, endoscopic findings, radiologic findings, diagnostic methods, management, and clinical outcomes were used for descriptive analysis. RESULTS: Of the 2674 ERCP procedures performed during the 71-mo study period, only six (0.22%) resulted in perforations (male/female, 2/4; median age: 84 years; age range: 57-97 years). The cases included an endoscope-related duodenal perforation, two periampullary perforations related to endoscopic sphincterotomy, two periampullary perforations related to endoscopic papillary balloon dilation, and a periampullary or bile duct perforation secondary to endoscopic instrument trauma. No cases of guidewire-related perforation occurred. The video endoscope system employed in all procedures was only able to immediately detect the endoscope-related perforation; the other five perforation cases were all detected by subsequent digital fluoroscope applied intraoperatively (at a median post-ERCP intervention time of 15 min). Three out of the six total perforation cases, including the single case of endoscope-related duodenal injury, were surgically treated; the remaining three cases were treated with conservative management, including trans-arterial embolization to control the bleeding in one of the cases. All patients recovered without further incident. CONCLUSION: ERCP-related perforations may be difficult to diagnose by video endoscope and digital fluoroscope detection of retroperitoneal free air or contrast medium leakage can facilitate diagnosis.

A 40-year-old man, resident of a rural area of Rajasthan state of India presented with recurrent biliary colic and fever since last 2 years. Examination was normal and investigations revealed a dilated common bile duct with elevated alkaline phosphatase. Magnetic resonance cholangiopancreatography revealed a dilated biliary system without any evident cause. Patient was subjected to endoscopic retrograde cholangioancreatography and it demonstrated biliary dilatation with a linear filling defect in lower common bile duct, further sphinicterotomy was done and a live Fasciola hepatica was extracted using a biliary basket.

A 48-year-old man with locally advanced pancreatic cancer underwent combined treatment with gemcitabine and proton radiation therapy. Because of subsequent obstruction of the common bile duct, a metallic biliary stent was placed and he received further gemcitabine chemotherapy. During chemotherapy, he developed an acute abdomen with a sudden-onset of tarry stool and jaundice. Gastroduodenoscopy revealed hemobilia from the biliary metallic stent. Contrast-enhanced abdominal computed tomography revealed the presence of a pseudoaneurysm arising from the right hepatic artery adjacent to the top of the stent. Hemostasis of the right hepatic artery pseudoaneurysm was achieved via transcatheter arterial embolization using cyanoacrylate.

A 46-year-old man was admitted with obstructive jaundice and cross-sectional imaging with computed tomography suggested distal biliary obstruction. A distal common bile duct stricture was found at endoscopic retrograde cholangiopancreatography (ERCP) and cytology was benign. A 6 cm fully covered self-expanding metal stent (SEMS) was inserted across the stricture to optimize biliary drainage. However, the SEMS could not be removed at repeat ERCP a few months later. A further fully covered SEMS was inserted within the existing stent to enable extraction and both stents were retrieved successfully a few weeks later. Fully covered biliary (SEMS) are used to treat benign biliary strictures. This is the first reported case of inability to remove a fully-covered biliary SEMS. Possible reasons for this include tissue hyperplasia and consequent overgrowth into the stent proximally, or chemical or mechanical damage to the polymer covering of the stent. Application of the stent-in-stent technique allowed successful retrieval of the initial stent.
