Prophylactic Abdominal Drainage vs no Drainage After Distal Pancreatectomy

A prospective, randomised, multicentre, multicentre, randomised non-inferiority study is designed. The aim is to study whether patients who undergo distal pancreatectomy can benefit from the non-placement of a drain in terms of clinically relevant postoperative pancreatic fistula and Clavien-Dindo morbidity greater than or equal to 3. Information will be collected for all patients undergoing distal pancreatectomy surgery at the collaborating centres who, upon invitation, voluntarily agree to participate in the study. Those who have agreed to participate, given written consent and meet the inclusion criteria and none of the exclusion criteria will be randomly assigned to one of the following treatment groups: * Control group: patients who, after distal pancreatectomy, in whom abdominal drainage is placed. * Intervention group: patients who, after distal pancreatectomy, will be omitted the placement of an abdominal drain. Following the postoperative pancreatic fistula score according to the DISPAIR criteria, patients included in the present study will be stratified according to the preoperative risk of postoperative pancreatic fistula into: extreme, high, moderate and low. The standards of surgical technique to be followed in both open and minimally invasive distal pancreatectomy were agreed by consensus. Each patient will be followed up for 6 months from the time of randomisation (day of surgery).Those responsible for the recruitment and selection of patients for inclusion in the research project belong to the Multidisciplinary Committee of Hepatobiliary and Pancreatic Surgery of each centre. Surgical intervention, postoperative management and perioperative morbidity will be evaluated by the surgeon responsible for the patient. A patient recruitment period of 2 years is estimated. After a follow-up period of 6 months, an analysis of postoperative pancreatic fistula rate, perioperative morbidity, biochemical parameters and quality of life will be performed.
