Brief summary: Pancreaticoduodenectomy is the most performed pancreatic surgery for malignant or premalignant tumors of the region of the head of the pancreas. Its post-operative morbidity is very high, over 40%. There is very little data on the impact of microbiota on complications after pancreatic surgery. The purpose of this research is to study the correlation between the microbiota (fecal, blood, oral, biliary, pancreatic and intestinal microbiota) and the postoperative complications in patients who undergo pancreaticoduodenectomy.

Detailed description: After pancreaticoduodenectomy, the post-operative complications can be surgical (pancreatic fistula, gastroparesis) but also infectious, digestive (diarrhea) and lead to malnutrition. They are responsible for prolonged post-operative hospitalizations, impaired quality of life of patients and induce a delay in the implementation of adjuvant chemotherapy, or even an impossibility to achieve it. The absence of adjuvant chemotherapy adversely affects the prognosis of patients, by increasing the rate of recurrence and decreased survival. There is therefore a real oncological benefit in finding solutions to reduce the number and severity of these complications. A change in post-operative microbiota composition has been shown to play a role in the development of post-surgical anastomotic fistulas in colorectal cancer. Despite their importance, there is very little data on the impact of microbiota on complications after pancreatic surgery. We postulate that microbiota variations could have an impact on early and late post-operative complications after pancreaticoduodenectomy. Any patient hospitalized at the Toulouse University Hospital with an indication of a pancreaticoduodenectomy will be offered to participate in this study. Microbiota analysis will be carried out on different samples: blood, stool and saliva samples will be collected during the surgery, between J5 and J10 (post-operative during hospitalization) and at 3 and 6 months after the surgery. Bile, pancreatic and intestinal mucosa samples will only be collected during the surgery. Complications will be collected throughout this study. This study will not create any additional constraints on patient management. The follow-up period will be 6 months. This follow-up period will be fixed for all patients included. The microbiota analyses will be centrally determined during the study.
