Abstract
BACKGROUND/AIM: The aims of this study were to clarify optimal type and management of preoperative biliary drainage (PBD) in patients with obstructive jaundice who underwent pancreatoduodenectomy (PD). PATIENTS AND METHODS: A total of 156 patients with obstructive jaundice who underwent PD were enrolled. We compared clinical variables and postoperative complications between patients who underwent endoscopic retrograde biliary drainage (ERBD) and those who underwent endoscopic nasobiliary drainage (ENBD). RESULTS: All patients underwent PBD, with ERBD in 117 and ENBD in 39. The incidence of infectious complications and clinically relevant pancreatic fistula (CR-PF) were significantly higher in the ERBD group (39% vs. 13%, p=0.012 and 39% vs. 10%, p<0.00001, respectively). However, there was no significant difference in the postoperative complications between two groups when the duration of drainage exceeded 30 days. CONCLUSION: ERBD should not be performed in patients with obstructive jaundice prior to PD because of the increased rates of infectious complications and CR-PF following PD, and ENBD should be chosen instead. Furthermore, PD should be performed within 30 days of drainage period in patients with ENBD.
