Background/AimsDespite advances in preoperative evaluation and postoperative care, intervention, especially surgery, for relief of obstructive jaundice still carries high morbidity and mortality rates. In obstructive jaundice, intestinal barrier dysfunction has been postulated to be a key factor contributing to high postoperative morbidity and mortality rates. Since surgery in patients with jaundice is thought to increase the risk of postoperative complications, preoperative biliary drainage (PBD) was introduced to improve the postoperative outcome. To date, whether biliary drainage should be routinely performed in patients with jaundice undergoing a pancreatoduodenectomy remains controversial, and the effect of biliary drainage on the intestinal barrier function in obstructive jaundice remains unknown.ResultsBiliary drainage is almost exclusively associated with beneficial results, such as improved intestinal barrier function in experimental models. However, clinical data in this field are limited, indirect and remain controversial. Most importantly, routine PBD will result in a highly procedure-related complication rate and an increase in operative infectious complications.ConclusionsPBD should not be performed routinely, unless further improved PBD techniques would become available in clinical studies. Future studies should focus on PBD techniques, and then on the effects of biliary drainage on intestinal mucosa in obstructive jaundice in clinical.
