Background: 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. Methods: 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. Results: 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. Conclusion: CBD stenting in patients with biliary pancreatitis and gallstone could reduce the risk of recurrence and remigration of gallstones in delayed cholecystectomy cases.

Recent research is recognizing that multicriteria decision making should take into account the concepts of uncertainty, risk, and confidence. In some cases, precise determination of the exact value of the attributes is difficult. Consequently, to surmount this potential problem, their values are considered as fuzzy and intervals. The elimination and choice translating reality (ELECTRE) is one of the most widely used methods to rank a set of alternatives versus a set of criteria to reflect the decision maker’s preference. What is customary in almost all recent papers regarding ELECTRE is the utilization of fuzzy concepts in decision-making process. In this paper, we propose a novel algorithmic ELECTRE method which assimilates the concepts of interval weights and data for the facilitation of evaluation of a set of alternatives against a set of criteria in this situation. Finally, the executive procedure of our proposed ELECTRE method is illustrated by applying it to the problem of supplier selection. [ABSTRACT FROM AUTHOR]
