    Background. Endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD) are both used to resolve jaundice before surgery for perihilar cholangiocarcinoma (PHC). PTBD has been associated with seeding metastases. The aim of this study was to compare overall survival (OS) and the incidence of initial seeding metastases that potentially influence survival in patients with preoperative PTBD versus EBD. Methods. Between 1991 and 2012, a total of 278 patients underwent preoperative biliary drainage and resection of PHC at 2 institutions in the Netherlands and the United States. Of these, 33 patients were excluded for postoperative mortality. Among the 245 included patients, 88 patients who underwent preoperative PTBD (with or without previous EBD) were compared to 157 patients who underwent EBD only. Survival analysis was done with Kaplan-Meier and Cox regression with propensity score adjustment. Results. Unadjusted median OS was comparable between the PTBD group (35 months) and EBD-only group (41 months; P = 0.26). After adjustment for propensity score, OS between the PTBD group and EBD-only group was similar (hazard ratio, 1.05; 95 % confidence interval, 0.74-1.49; P = 0.80). Seeding metastases in the laparotomy scar occurred as initial recurrence in 7 patients, including 3 patients (3.4 %) in the PTBD group and 4 patients (2.7 %) in the EBD-only group (P = 0.71). No patient had an initial recurrence in percutaneous catheter tracts. Conclusions. The present study found no effect of PTBD on survival compared to patients with EBD and no increase in seeding metastases that developed as initial recurrence. These data suggest that PTBD can safely be used in preoperative management of PHC

    <p>Abstract</p> <p>Background</p> <p>The aim of the study was to assess the knowledge and practices of primary care physicians in diagnosis and management of <it>Helicobacter pylori (H. pylori) </it>infection in developing country.</p> <p>Methods</p> <p>This convenient sample based, cross sectional study was conducted in primary care physicians of Karachi, Pakistan from March 2008 to August 2008 through a pretested self-designed questionnaire, which contained 11 items pertaining to <it>H. pylori </it>route of transmission, diagnosis, indication for testing, treatment options, follow up and source of information.</p> <p>Results</p> <p>Out of 509 primary care physicians, 451 consented to participate with the response rate of 88.6%. Responses of 426 primary care physicians were analyzed after excluding 19 physicians. 78% of the physicians thought that contaminated water was the source of spread of infection, dyspepsia was the most frequent indication for investigating <it>H. pylori </it>infection (67% of the physicians), while 43% physicians were of the view that serology was the most appropriate test to diagnose active <it>H. pylori </it>infection. 77% of physicians thought that gastric ulcer was the most compelling indication for treatment, 61% physicians preferred Clarithromycin based triple therapy for 7–14 days. 57% of the physicians would confirm <it>H. pylori </it>eradication after treatment in selected patients and 47% physicians preferred serological testing for follow-up. In case of treatment failure, only 36% of the physicians were in favor of gastroenterologist referral.</p> <p>Conclusion</p> <p>The primary care physicians in this study lacked in knowledge regarding management of <it>H. pylori </it>infection. Internationally published guidelines and World gastroenterology organization (WGO) practice guideline on <it>H. pylori </it>for developing countries have little impact on current practices of primary care physicians. We recommend more teaching programs, continuous medical education activities regarding <it>H. pylori </it>infection.</p

    Rupture of Hepatocellular Carcinoma into the Biliary System with Resulting Bile Duct Thrombi: Report of Two Cases

    We report two cases of hepatocellular carcinoma revealed by jaundice and the presence of free-floating tumoural fragments within the biliary system. Two men (one of 64 and one of 73) presented with isolated jaundice. The results from ultrasound, CT and MRI were suggestive of a cholangiocarcinoma. Surgical intervention demonstrated bile duct thrombi from the primary tumour causing obstructive jaundice

    Objective To evaluate the long-term outcome of autoimmune pancreatitis. Methods Patients with at least 2 years of follow-up were included. Information was collected regarding disease characteristics, treatment outcome, diagnosed malignancies, and mortality. In addition, pancreatic function and quality of life were assessed prospectively. Results 107 patients were included (87% men, 90% with type 1), with a median follow-up of 74 (interquartile range, 49-108) months. One third was operated for suspected pancreatic cancer (32%). Most patients were (successfully) treated with steroids (83%), but relapses were common (52%), for which no risk factors could be identified. Pancreatic carcinoma was not observed. Prospective data were obtained from 64%, as 17% had died, 7% were lost to follow-up, and 13% refused to participate. After a median of 75 (interquartile range, 50-106) months, 46% still used active treatment. Exocrine and endocrine insufficiencies were highly prevalent (82% and 57%, respectively). Quality of life and survival were not impaired, as compared with a reference population. Conclusions Despite an excellent initial treatment response, relapses are common, even in type 2, and almost half of the patients require maintenance therapy. Pancreatic insufficiency is highly prevalent, which calls for active screening. Pancreatic cancer was not observed, and quality of life and survival are not impaired
