Association of bacteria in pancreatic fistula fluid with complications after pancreatic surgery

BJS Open, Volume 4, Issue 3, Page 432-437, June 2020., 2020
This study showed that, despite the absence of intestinal lumen opening, pancreatic fistulas after distal pancreatectomy frequently contain intestinal bacteria, which markedly worsen the clinical outcome. Understanding the pathogenetic mechanism behind this high prevalence of intestinal bacteria within distal pancreatectomy‐associated pancreatic ...
