RESUMO
INTRODUCTION: Patients with unexplained dilated common bile duct (CBD) and/or dilated main pancreatic duct (MPD) on noninvasive abdominal imaging tests are often referred for endoscopic ultrasound (EUS) in order to rule out biliopancreatic cancer. The aim of the study was to evaluate the diagnostic yield of EUS in this patient group. METHODS: A prospective study was conducted. Patients with unexplained dilated CBD and/or MPD on abdominal imaging, who underwent EUS, were enrolled. RESULTS: Fifty-four patients underwent EUS (CBD dilation n=38, MPD dilation n=5 or both n=11). In 31/54 patients (57.4%), EUS revealed pathologic findings. Sixteen patients (29.6%) had EUS evidence of biliopancreatic cancer and 15 patients (27.7%) had benign pathology. Ten (62.5%) of the patients with biliopancreatic cancer had MPD dilation. MPD dilation was significantly associated with malignancy (P=0.017). CONCLUSION: Patients with unexplained dilated MPD on noninvasive image have a high risk of biliopancreatic malignancy detected by EUS.

INTRODUCTION: Disconnected pancreatic duct syndrome (DPDS) is defined as the complete disruption of the main pancreatic duct, the result are peripancreatic fluid collections or pancreatic leaks. The aim of this study was to report the results of derivative endoscopic treatment of DPDS in a long-term follow-up period. PATIENTS AND METHODS: We performed a retrospective analysis of prospectively collected data. Endoscopic treatment consisted of transmural drainage with 2 double pigtail plastic stents (7 F and 4 cm) deployed under endoscopic ultrasound guidance. RESULTS: In total, 21 patients were included in our study. There were 15 (71%) men and the median age was 36 years (range, 23 to 86 y). The principal etiology of DPDS was acute pancreatitis. A total of 20 (95.2%) patients were diagnosed with DPDS by endoscopic pancreatography and only 1 (4.8%) patient by magnetic resonance cholangiopancreatography (MRCP). The median follow-up time was 28 months (range, 7 to 76 mo). Technique success was 100% and initial clinical success was 80.9% (17/21). Three (17.6%) of these patients required a new endoscopic procedure with success in all cases. During follow-up, 11 (52%) patients developed diabetes mellitus and 3 patients (14%) developed exocrine pancreatic insufficiency. There were 5 (15%) patients with complications. CONCLUSION: According to our data, endoscopic treatment with the placement of a permanent indwelling transmural stents is a useful and safe tool for the treatment of DPDS.

INTRODUCTION AND AIM: Endoscopic treatment is the best option for patients with postsurgical stricture of main biliary duct. There is scarce information about the incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) complications in this condition. The aim was to evaluate the incidence of complications and the associated risk factors in patients undergoing ERCP for postcholecystectomy biliary stricture. MATERIALS AND METHODS: Prospective analysis of patients with postsurgical stenosis of main biliary duct was carried out. Rate of post-ERCP complications was determined and the associated risk factors were analyzed. RESULTS: A total of 25 patients were included. The success rate of endoscopic treatment was 92% (n=23). Two patients had recurrence of stricture with median follow-up of 23 months (range, 0.3 to 65.4 mo). Five patients (20%) developed acute pancreatitis after ERCP. No risk factors were detected in multivariate analysis. CONCLUSION: Incidence of post-ERCP pancreatitis is high in patients with biliary stricture associated with surgical procedures.

BACKGROUND: Ampulla of Vater's tumors (AVT) are rare and account for 0.2% of neoplasia in necropsies. The stage, comorbidities and surgical experience are crucial for prognosis. The aim of this work is to report the clinical characteristics, treatment and complication of a group of patients with AVT. MATERIAL AND METHODS: Patients with AVT were included in a retrospective manner. Descriptive statistics was used and data were shown as means and SD. RESULTS: One hundred and six patients were included with a mean age of 58.5 +/- 14 years and 58% were women. Jaundice was the most common clinical data and it was present in 90% of cases. Two-thirds of patients underwent a Whipple surgical procedure. Complications of surgery were present in 35% of cases and abdominal sepsis and pancreatic fistulae were the most common (32% and 29%, respectively). Adenocarcinoma was the most common histological type and 39% of cases were in stage IV at diagnosis. Age higher or equal to 65 years was associated with less surgical possibilities. Melena at presentation was associated with a higher probability of surgical resection. CONCLUSION: The probability of surgical resection is lower in patients older than 65 years and higher in those with melena at the diagnosis.

The aim was to evaluate the initial success, rebleeding rate, need for emergent surgery, and mortality rates of patients with Dieulafoy's lesion (DL) and endoscopic treatment (ET). Patients with DL from a tertiary center were included. We included 20 patients with follow-up of 90 (60-550) days. The lesser curvature was the most common localization. Initial success, rebleeding, and emergent surgery requirement were observed in 90%, 10%, and 15%, respectively. No objective variables were related with response to ET. In conclusion, ET is secure and useful in patients with DL and it must be considered as the first-line treatment modality.
