In patients with severe biliary pancreatitis, delayed cholecystectomy associated with a high risk of recurrence is recommended. The current study aimed to evaluate the effect of common bile duct (CBD) stenting on reducing gallstones migration and recurrence of symptoms in patients with pancreatitis and delayed cholecystectomy candidates. To this purpose, the randomized, controlled clinical trial was performed on 40 patients with biliary pancreatitis who were candidates for delayed cholecystectomy. Patients were randomly divided into two groups of A and B that underwent CBD stenting after ERCP and received endoscopic treatment without stenting, respectively. A checklist recorded demographics and complications. Group A was followed up after four weeks to remove the stent and record the complications. Group B underwent MRCP to examine the migration of new gallstones as well as the complications. Of the 40 patients, 20 subjects (11 males and 9 females) were allocated to each group, matched for demographic variables. In the one-month follow-up, only one subject in group A manifested symptoms of gallstone migration and recurrence, while in group B, recurrence was observed in 6 patients (P = 0.037). There was no significant difference in the success rate of ERCP and the incidence of complications between the two groups. CBD stenting in patients with biliary pancreatitis and gallstone could reduce the risk of recurrence and remigration of gallstones in delayed cholecystectomy cases.

Background Hepatitis D virus (HDV) is a defective RNA virus that depends on the hepatitis B surface antigen (HBsAg) of hepatitis B virus for its replication, developing exclusively in patients with acute or chronic hepatitis B. There are little data regarding the routes of HDV transmission in Iran. The risk factors for HDV infection in Iran are blood transfusion, surgery, family history, Hejamat wet cupping (traditional phlebotomy), tattooing, war injury, dental interventions, and endoscopy. Objectives We performed this study to determine the prevalence of hepatitis D in the general population of Qom province and the potential risk factors for acquiring HDV. Patients and methods This cross-sectional study collected 3690 samples from 7 rural clusters and 116 urban clusters. HBs antigen was measured, and if the test was positive, anti-HDV was measured. Ten teams, each consisting of 2 trained members, were assigned to conduct the sampling and administer the questionnaires. The data were analyzed using SPSS. Results Forty-eight subjects (1.3%) suffered from hepatitis B, and 1 HBsAg-positive case had HDV infection. The prevalence of hepatitis D infection in Qom Province was 0.03%. The prevalence of hepatitis D infection in HBsAg-positive cases was 2%. Our anti-HDV-positive case had a history of tattooing, surgery, and dental surgery. There was no significant relationship between tattooing, surgery history, or dental surgery and hepatitis D infection. Conclusions The prevalence of hepatitis D in Qom is the the lowest in Iran, similar to a study in Babol (north of Iran).
