Summary
Preoperative bile duct stenting significantly increases bacterial contamination but does not raise postoperative cholangitis or complications when managed with appropriate antibiotics and flushing. Careful patient selection for biliary drainage is essential.
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Surgical Infectious Diseases
Background:
- Bile duct stenting in pancreatic surgery aims to improve outcomes but risks bacterial contamination and cholangitis.
- A critical evaluation of stenting's impact on bile duct health is necessary.
Purpose of the Study:
- To investigate the effect of preoperative bile duct stenting on intraoperative bile cultures.
- To assess the impact of stenting on postoperative outcomes in patients undergoing pancreatic surgery.
Main Methods:
- Prospective analysis of intraoperative bile duct cultures in 80 patients undergoing surgery for periampullary diseases.
- Patients received antibiotic prophylaxis and retrograde bile duct flushing.
- Comparison between patients with and without preoperative biliary drainage.
Main Results:
- 98% of stented patients had positive bile cultures versus 21% without drainage (P<0.001).
- Postoperative acute cholangitis occurred in 2% of stented patients versus 13% without drainage (P=0.231).
- Major complications were similar between groups (12% stented vs. 8% non-stented, P=0.817).
Conclusions:
- Preoperative biliary drainage causes near-universal bile duct bacterial contamination.
- With appropriate prophylaxis and flushing, stenting does not increase postoperative cholangitis or morbidity.
- Individual patient assessment for the benefits of preoperative biliary drainage is crucial.
