Surgery is required for the treatment of many pancreatic conditions, either malignant or benign. Mortality of pancreatic surgery can be up to 3% even in expert centers. Morbidity is high, postoperative pancreatic fistula (POPF) being the main postoperative complication. In its current definition (drain output of any measurable fluid >= postoperative day 3 with amylase content >3 times the serum amylase activity and with clinical consequence), the incidence of postoperative PF is between 15 and 30 %. Most POPF resolve spontaneously but when refractory POPF occurs, it may lead to severe complications. POPF severity is graded as follows: grade B in case of change in medical management: infection without organ failure, specific medication (total parenteral nutrition, somatostatin analogs, antibiotics), persistent drainage > 3 weeks, angiographic procedure for bleeding, prolonged hospital stay; grade C in case of reoperation or PF-related organ failure or death. No specific prophylactic treatment of POPF is currently recommended by clinical guidelines. In clinical research, many prophylactic strategies have been attempted with partial efficacy. Endoscopic pancreatic sphincterotomy with plastic stent placement is effective in pre-and postoperative management of pancreatic fistula but with the need of a highly competent interventional endoscopist. Intrapapillary botulinum toxin injection is believed to induce relaxation of the pancreatic sphincter, leading to a " pharmacological " pancreatic sphincterotomy without any morbidity. A recent phase I/II prospective study has shown promising results in this indication, with no clinically relevant pancreatic fistula when botulinum toxin was injected. Based on this observation we hypothesize that intrapapillary botulinum toxin injection during an endoscopic procedure before surgery could be effective for the prevention of post-surgical pancreatic fistula

Secondary | Quality of life EQ-5D-5L questionnaire | The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state : LEVEL 1: indicating no problem LEVEL 2: indicating slight problems LEVEL 3: indicating moderate problems LEVEL 4: indicating severe problems LEVEL 5: indicating unable to/extreme problems | 3 months | |
Secondary | Number of sides effects (complications) related to the endoscopic botulinum toxin injection | number of sides effects (complications) related to the endoscopic botulinum toxin injection | 3 months |
