Objective: This study was an investigation of the experience of a single institution with cases of definitive or suspected Mirizzi syndrome (MS) based on endoscopic retrograde cholangiography (ERCP) findings and the correlation of the preliminary diagnosis to the final diagnosis. Materials and Methods: This retrospective study was performed with the data of 58 patients treated between January 2010 and December 2019. Cases where the gallbladder or cystic duct compression of the main hepatic duct was clearly visible as the cause of biliary obstruction were classified in the ERCP report as definitive MS, and those with only a suspicion of compression were reported as suspected MS. In all, 22 patients had a definitive diagnosis of MS and 36 patients had a report of suspected MS. The ERCP reports were compared with surgical reports and the results were analyzed. Results: Examination of the surgical reports of the 22 patients with a preliminary diagnosis of definitive MS based on the ERCP findings revealed that MS was confirmed in 15 patients (68%) and malignancy in 3 patients (14%). No pathology other than gallstones was detected in 4 patients (18%). Review of the surgical reports of the 36 patients with a preliminary diagnosis of suspected MS indicated that MS was detected in 5 patients (14%), malignant stenosis in 20 patients (55%), chronic pancreatitis in 1 patient (3%), and a choledochal cyst in 1 patient (3%). Of the 23 patients with malignancy, cholangiocarcinoma was detected in 16 patients, pancreatic cancer in 3 patients, and gallbladder cancer in 3 patients. Conclusion: The results of this study illustrate the difficulty in accurately diagnosing MS and the frequent confusion with malignancy. [ABSTRACT FROM AUTHOR]

Abstract Background Ectopic opening of the common bile duct into the duodenal bulb (EO-CBD-DB) is a rare disease that may be complicated by duodenal ulcer, deformity, stenosis and biliary stones. The aim of this study is to report clinical presentations, endoscopic diagnosis and treatment of this entity as well as to investigate its association with duodenal stenosis. Methods Gastroduodenoscopic findings and radiological imaging were evaluated for ectopic papilla and duodenal stenosis. Diagnostic methods, endoscopic procedures and long-term outcomes of the endoscopic treatment were presented. Results EO-CBD-DB was found in 74 (77.1%) of the 96 patients with duodenal deformity/stenosis (79 male, 17 female, mean age: 58.5, range: 30-87 years). The papilla with normal appearance was retracted to the bulb in 11 while it was at its usual location in the remaining 11. The history of biliodigestive surgery was more common in patients with EO-CBD-DB who were frequently presented with the common bile duct stone-related symptoms than the other patients. Thirteen (17.6%) of the patients with EO-CBD-DB were referred to surgery. Endoscopic treatment was completed in 60 (81.1%) patients after an average of 1.7 (range: 1-6) procedures. These patients were on follow-up for 24.8 (range: 2-46) months. Endoscopic intervention was required in 12 (20%) of them because of recurrent biliary problems. Treatment of the patient who had stricture due to biliary injury during laparoscopic cholecystectomy is still continued. Conclusions The presence of EO-CBD-DB should be considered particularly in middle-aged male patients who have duodenal deformity/stenosis. Endoscopic treatment is feasible in these patients. The long-term outcomes of endoscopic therapy need to be compared with surgical treatment.

Background/aim: We aimed to present the endoscopic ultrasound (EUS) features of gastric lesions suggesting gastric ectopic pancreas during upper gastrointestinal endoscopy that were diagnosed in our gastroenterology unit, which is a tertiary center for endoscopic procedures in Turkey. Materials and methods: The data of patients who underwent upper gastrointestinal EUS in our center between April 2012 and July 2014 were retrospectively analyzed. Results: All of the lesions suggesting gastric ectopic pancreas were localized in the gastric antrum. Thirty-six of 44 lesions (81.1%) showed central dimpling. Lesion borders were shown to be definite in 10 (22.7%) lesions, whereas the borders of 34 lesions (77.3%) were indefinite. Thirty-nine lesions (88.6%) had heterogeneous and 5 lesions (11.4%) had homogeneous echo patterns; whereas 29 lesions (65.9%) were hypoechoic, 9 lesions (20.5%) were hyperechoic and 6 lesions (13.6%) had mixed echogenicity. Forty-two lesions (95.5%) were shown to affect only a single sonographic layer of the gastric wall. Conclusion: EUS features of lesions that strongly suggest gastric ectopic pancreas endoscopically, without any histopathological evidence and without either endoscopic or surgical resection, are as follows: indefinite border appearance, minimal heterogeneous hypoisoechoic echo pattern, existence of anechoic duct-like structures inside the lesion, common localization in the submucosal layer, and existence of umbilication.

Background/aim: We aimed to examine the effect of plastic biliary stenting in the treatment of common bile duct (CBD) stones. Materials and methods: The data of 13,034 patients in our unit who had endoscopic retrograde cholangiopancreatography (ERCP) between 2008 and 2015 were scanned retrospectively. Results: A biliary stent was placed in 61 of 74 patients. While the plastic biliary stent was placed in patients, the mean stone size after the 1st ERCP was 20 mm and the bile duct size was 13 mm. At the time of the 2nd ERCP conducted approximately 73.9 days later, the mean stone size was found to be 15 mm and the bile duct size was 12 mm. With recurrent ERCPs, the CBD stone was successfully removed in 53 patients but could not be removed in 8 patients. Among the 53 successful cases, 29 removals were successful in the 2nd ERCP session, 16 were successful in the 3rd session, 2 were successful in the 4th session, 1 was successful in the 5th session, 4 were successful in the 6th session, and 1 was successful in the 7th session. Conclusion: For CBD stones that cannot be removed by standard methods, temporary plastic stenting is an alternative method. [ABSTRACT FROM AUTHOR]

Background Double Balloon Enteroscopy (DBE) provides the opportunity not only to investigate but also apply endoscopic therapeutic interventions for small intestinal disturbances. The aim of this study is to assess the indications, diagnosis, therapeutic interventions, complications and safety in clinical practise of DBE procedures that have been performed in our clinic. Material-methods The data of patients who had undergone DBE procedure in our clinic between October 2007 and December 2014 were retrospectively investigated. All features including indications, findings, histopathological results, applied interventions and complications due to procedure were noted. Results A total of 297 patients, 160 (53,9%) male and 137 (46,1%) female were enrolled in the study. Total number of procedures for these 297 patients were 372 [256 (68,8%) oral and 116 (31,2%) anal]. Mean age of the patients was 46,9 (14–94) years. The most common indications were; obscure gastrointestinal (GI) bleeding (28,3%), iron deficiency anaemia (17,5% ) and abnormal findings in a prior imaging study (13,8%), respectively. The rate of new diagnosis with DBE was 11.8%, where the rate for confirmation of a possible diagnosis was 16.2%, rate of endoscopic treatment with definite diagnosis was 11%, rate for ruling out possible diagnosis or showing normal findings was 34.7% and rate for insufficient or unsuccessful procedures was 26.3%. Ulcers, inflammation and erosions (13%), polyposis syndromes (9.8%) and vascular pathologies (7.4%) were the most common endoscopic findings. Conclusion Our study shows that DBE has high efficacy for diagnosis and ability to perform treatment of small intestinal disturbances with safety. [ABSTRACT FROM AUTHOR]

Introduction. Using single anesthetic agent in endoscopic retrograde cholangiopancreatography (ERCP) may lead to inadequate analgesia and sedation. To achieve the adequate analgesia and sedation the single anesthetic agent doses must be increased which causes undesirable side effects. For avoiding high doses of single anesthetic agent nowadays combination with sedative agents is mostly a choice for analgesia and sedation for ERCP. Aim. The aim of this study is to investigate the effects of propofol alone, propofol + remifentanil, and propofol + fentanyl combinations on the total dose of propofol to be administered during ERCP and on the pain scores after the process. Materials and Method. This randomized study was performed with 90 patients (ASA I-II-III) ranging between 18 and 70 years of age who underwent sedation/analgesia for elective ERCP.The patients were administered only propofol (1.5mg/kg) in Group I, remifentanil (0.05 µg/kg) + propofol (1.5mg/kg) combination in Group II, and fentanyl (1 µg/kg) + propofol (1.5mg/kg) combination inGroup III. All the patients' sedation levels were assessed with the Ramsey Sedation Scale (RSS). Their recovery was assessed with the Aldrete and Numerical Rating Scale Score (NRS) at 10 min intervals. Results. The total doses of propofol administered to the patients in the three groups in this study were as follows: 375mg in Group I, 150mg in Group II, and 245mg in Group III. Conclusion. It was observed that, in the patients undergoing ERCP, administration of propofol in combination with an opioid provided effective and reliable sedation, reduced the total dose of propofol, increased the practitioner satisfaction, decreased the pain level, and provided hemodynamic stability compared to the administration of propofol alone.

Aim. Differentiation of malignant and benign strictures constitutes a problem despite the increasing experience of the endoscopists, radiologists, and pathologists. The aim of our study is to determine the factors that affect the efficacy of the ERCP guided brush cytology in PBS and to evaluate its diagnostic success when used alone and together with tumor markers. Method. The data from brush cytologies of 301 PBS patients were collected retrospectively and analyzed. The final diagnosis was approved based on the histological examination of the tissue taken surgically or by other methods. In the absence of a histological diagnosis, the final diagnosis was based on radiological studies or the results of a 12-month clinical follow up. Results. A total of 28 patients were excluded from the study. From the remaining 273 patients 299 samples were analyzed. The sensitivity and the specificity of brush cytology in diagnosing malignancy are 62.4% and 97.7, respectively. The sensitivity of brush cytology increased to 94.1% when combined with CA-19.9 and CA-125. Conclusion. Brush cytology is a useful method in diagnosing pancreaticobiliary strictures. Advanced age, stricture dilatation before sampling, the presence of a mass identified by radiological studies, high levels of CA-19.9, ALT, and total bilirubin increase the sensitivity of brush cytology.

Background: The diagnosis of primary sclerosing cholangitis (PSC) is reached by typical cholangiographic findings and liver biopsy. The characteristic cholangiographic abnormalities consist of multifocal strictures and dilatations in the intrahepatic and/or extrahepatic bile ducts. Patients may develop cirrhosis and portal hypertension. Endoscopy may reveal esophageal/gastric varices and portal hypertensive gastropathy. Objective: To define a novel endoscopic finding in patients with PSC. Design: Case series. Setting: Single tertiary referral center in Turkey. Patients: Ten patients with PSC, 16 with liver cirrhosis, and 10 with PSC-like cholangiogram. Interventions: Inspection of papilla with duodenoscope and ERCP. Main Outcome Measurements: Retraction of papilla into the duodenum wall. Results: Ten patients with PSC (8 male, 2 female, mean age 38 y) underwent ERCP at our institution. Retraction of papilla into the duodenum wall was observed in 7 patients (70%). The mean time elapsed between the retraction of the papilla and onset of PSC was 5.1 years (range 2-7 y). In patients with retraction of the papilla, both of the intrahepatic and extrahepatic bile ducts were involved; however, only the intrahepatic bile ducts were involved in patients with no retraction of papilla. Of 7 patients with retraction of papilla, 5 had a history of sphincterotomy procedure 5.4 years previously (range 5-6 y). Two patients had native papilla. None of the patients had end stage liver disease. Retraction of papilla was observed in none of the 16 patients with cirrhosis of the liver and in 10 with PSC-like cholangiogram. Limitations: Only observational; absence of surgical and/or pathologic evidence. Conclusions: Papilla may be embedded in the duodenum wall in some patients with PSC. Extrahepatic involvement seems to be necessary for the occurrence of this finding. [Copyright &y& Elsevier]

Background/aims: Retraction of the main papilla toward the biliary system was observed in 70% of patients with primary sclerosing cholangitis (PSC). However, this observation was confounded by the fact that all of the patients with this finding had a prior history of sphincterotomy. The aim of the present study was to observe whether main papillary retraction can be seen in patients with naïve papillae and accompanies the progression of the disease., Materials and Methods: The study was conducted in a single tertiary reference center and included 4 patients with PSC., Results: Main papillary retraction was seen to emerge with progression of PSC after an initial presentation with intra and extrahepatic involvement in 2 patients and after progression from intrahepatic to extrahepatic bile ducts in 1 patient. Main papillary retraction was seen in 2 patients with naïve papillae and could be detected by magnetic resonance cholangiography in 1 patient., Conclusion: Retraction of the main papilla can be seen in patients with PSC regardless of prior sphincterotomy history.

Congenital anomalies of pancreas and its ductal drainage are uncommon but in general surgically correctable causes of recurrent pancreatitis. A gastric duplication cyst communicated with an accessory pancreatic lobe is an extremely rare cause of recurrent pancreatitis, but an early and accurate diagnosis of this anomaly is important because suitable surgical treatment may lead to a satisfactory outcome. Herein, we presented multidetector computed tomography and magnetic resonance imaging findings of a gastric duplication cyst communicating with an accessory pancreatic lobe via an aberrant duct in a 29-year-old woman with recurrent acute pancreatitis and also reviewed other similar cases reported in the literature.
