Preoperative Stenting for Benign and Malignant Periampullary Diseases: Unnecessary if Not Harmful

Preoperative biliary drainage (PBD) is often performed in patients with jaundice with the presumption that it will decrease the risk of postoperative complications. PBD carries its own risk of complications and, therefore, has been controversial. Multiple randomized controlled trials and metaanalyses have shown that PBD has significantly increased overall complications compared with surgery alone. As such, the routine application of PBD should be avoided except in a subset of clinical situations. This is discussed in detail in this article.
