About

Postoperative pancreatic fistula (POPF) is a major source of morbidity and mortality after pancreatic resection, especially after distal pancreatectomy (PD). Today, POPF remains one of the main causes of hospital length of stay and healthcare costs. Numerous surgical techniques have been tested to reduce its incidence without success, so the current standard for the management of POPF, and the avoidance of associated complications, is intraoperative drain placement. However, surgically placed drains are not without risk. In recent years many studies, mostly retrospective, have attempted to determine whether omission of prophylactic drainage is associated with increased morbidity. These studies suggest that patients may benefit from not having a drain placed. This evidence challenges standard practice and the debate of whether or not to place a drain after distal pancreatectomy remains open. The investigators designed a prospective multicentre randomised non-inferiority study to determine whether prophylactic intraoperative drainage is associated with a lower morbidity rate after distal pancreatectomy.

Full description

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.

Inclusion and exclusion criteria

Inclusion Criteria:

• Adult patients (over 18 years of age) undergoing elective distal pancreatectomy surgery for any indication, with or without splenectomy, minimally invasive or open. It is not necessary to integrate gender perspective as it is not relevant and there is no influence on the results of POPF or morbidity.
• Signed informed consent was obtained from each of the patients included in the study.

Exclusion criteria

• Patients undergoing distal pancreatectomy as a secondary procedure
• Additional liver, gastric or colonic resection
• Pregnancy
• Participation in another study
• History of previous surgery involving the pancreas
• Patients with American Society of Anaesthesiologists classification 4
• Arterial resection other than the splenic artery
