Abstract
Introduction: Over 5.8 million abdominal operations and procedures were recorded in England between April 2021 and March 20221. Although a definition of major surgery has been proposed by the Delphi consensus among European Surgical Association members2, there is no clear consensus regarding which surgical procedures constitute major abdominal surgery (MAS). Despite this, multiple sources in the literature, including perioperative morbidity and mortality scoring systems, national audits, and private healthcare coding schedules3–5, have alluded to this type of surgery without any underlying qualification. To clarify this area, a scoping literature review was conducted to derive a definition of MAS, based on content analysis of the terminology used to describe major abdominal surgical procedures6. MAS was defined as an intraperitoneal operation with no primary involvement of the thorax, involving either luminal resection and/or resection of a solid organ associated with the gastrointestinal tract. The aim of the current study was to verify the discriminative ability of this hypothesized definition of MAS using real-world data analysis and unsupervised machine learning.
