Complications directly related to primary and secondary treatment divided into major and minor complications according to Clavien-dindo.
Complications include, but are not limited to: * Intra-abdominal abscess, defined as a radiologically confirmed accumulation of purulent fluid in a walled-off space within the abdominal cavity. * (Adhesive) bowel obstruction requiring readmission (diagnosis based on clinical signs and symptoms such as a history of constipation, nausea, vomiting and distended abdomen) * Superficial Surgical Site Infection, as defined by the CDC criteria.
