Effect of Bile Contamination on Immediate Outcomes after Pancreaticoduodenectomy for Tumor

Background The influence of preoperative biliary drainage on the postoperative course of patients undergoing pancreaticoduodenectomy (PD) remains controversial. Among drawbacks of biliary drainage, bile contamination and its consequences are incompletely evaluated. This study aimed to compare outcomes after PD in patients with sterile and those with infected bile. Study design Seventy-nine consecutive patients underwent PD for periampullary tumor with routine bile culture and antibiotic prophylaxis with cefazolin. The postoperative course of 35 patients with infected bile (group B+) was compared with that of 44 patients with sterile bile (group B−). Results The distribution of tumors was comparable except for ampullary carcinoma, which was more frequent in group B+ patients (p = 0.001). Interventional biliary endoscopy was performed preoperatively in 80% of patients in group B+ versus 14% in group B− (p Conclusions In patients undergoing PD, bile infection is related to previous interventional biliary endoscopy in 80% of patients and is associated with an increased rate of postoperative infections. During PD for ampullary carcinoma or after interventional biliary endoscopy, a specific antibioprophylaxis should be evaluated.
