title: A comprehensive classification of invasive procedures for treating the local complications of acute pancreatitis based on visualization, route, and purpose.
abstract: OBJECTIVE
  The lack of a system to classify invasive procedures to treat local complications of acute pancreatitis is an obstacle to comparing interventions. This study aimed to develop and validate a comprehensive multidisciplinary classification.
  
  
  METHODS
  Standardized terminology was used to develop a classification of procedures based on three key components: how the lesion is visualized, the route used during the procedure, and the procedure's purpose. Gastroenterologists, radiologists, and surgeons (n = 22) from three New Zealand centers independently classified 15 published technique descriptions. Inter-rater reliability was calculated for each component. The classification's clarity, ease of use, and potential to achieve its objectives were rated on a Likert scale.
  
  
  RESULTS
  The classification's clarity, ease of use, and potential to achieve its objectives had median scores of 4/5. Inter-rater reliability for visualization, route, and purpose components was substantial at 0.73 (95% CI 0.63-0.82), 0.79 (95% CI 0.70-0.87), and 0.64 (95% CI 0.53-0.74), respectively.
  
  
  CONCLUSIONS
  This article describes the development and validation of a comprehensive classification for the wide range of procedures used to treat the local complications of acute pancreatitis. It has substantial inter-rater reliability and high acceptability, which should enhance communication between clinicians and facilitate comparison between procedures.
