Abstract

Anastomotic biliary strictures (ABSs) are one of the most frequent adverse events that occur after orthotopic liver transplantation (OLT). Multiple plastic stents (MPS) have been validated for this indication. More recently, fully covered self-expandable metallic stents (FCSEMSs) have been used with positive outcomes, but also have a higher rate of migration, which may limit success. Our primary objective was to compare stent migration rates observed with standard FCSEMSs (Std-FCSEMSs) and so-called anti-migration FCSEMSs (Am-FCSEMSs), which are newly designed with reversed proximal side flaps. Secondary objectives were to compare rates of stricture resolution and procedure-related morbidity. We conducted a retrospective analysis of a subset of patients (FCSEMSs for post-OLT ABS) from 2 prospectively maintained databases of (1) OLT patients, and (2) ERCP and stent placement. Between January 2009 and January 2016, consecutive patients presenting with ABS after OLT referred to Cochin Hospital (Paris, France) for ERCP and receiving a FCSEMS were included. Exclusion criteria were any other cause of biliary stricture (ie, malignant stricture, ischemic origin), and biliary fistulae. One hundred twenty-five FCSEMSs (57 Am-FCSEMSs, 52 ...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
