"Snapshot" study worldwide over 3 months in 2021. Provide a verified record of true morbidity and mortality. Identify modifiable predicting factors of outcome. Obtain PubMed citable co-authorship,

The PancreasGroup.org team is conducting a "snapshot" clinical study investigating the outcomes of pancreatic surgery worldwide. This "collaborative" model for snapshot clinical studies is a well-established approach for assessing current practice in a short period of time.

There will be 3 months of prospective enrolment and 3 months follow up within a 12-month frame. The study will provide highly valuable data on outcomes after pancreatic surgery.

The investigators are aiming at providing a verified record of true morbidity and mortality in consecutive unselected patients. This way the investigators will help identify relevant, modifiable predicting factors for outcome after pancreatic surgery.

Inclusion Criteria:

• All indications (including benign and malignant)
• Open, laparoscopic or robotic.
• Elective or emergency.
• Partial or total pancreatectomies.
• Pancreatic tumour enucleations.
• Procedures with concomitant vascular or other organ resections.
• Pancreatic duct drainage procedures (e.g. Frey, Puestow, or Beger)
• Adults 18 years of age or older.

Exclusion Criteria:

• Pancreas or islet cell transplantation.
• Transcutaneous or transgastric imaging-guided ablation (e.g. RFA) or electroporation (e.g. NanoKnife).
• Endoscopic (e.g. endoscopic retrograde cholangiopancreatography, stent or lithotripsy) procedures.
• Endoscopic transgastric and surgical necrosectomies excluded.
• Patients less than 18 years of age excluded.

All adult patients undergoing pancreatic resection by surgeons at their respective centres are eligible for study inclusion.

PancreasGroup.org is a collaboration of all surgeons contributing data as equal partners. Each surgeon contributing data has access to analysis files of the entire database at any time point and the right to propose analyses and publish data as long as every surgeon contributing data are included as a group author in every publication and have an opportunity to review the data prior to submission. Each collaborator has access to their own data in a form of excel export file without requiring permission or approval by the PancreasGroup.org management committee.

The data will become available after the first and main publication of PancreasGroup.org. They will be available for at least 10 years.
