Prediction model for non-invasive quantitative evaluation of postoperative concurrent pancreatic fistula risk before pancreatic resection

Abstract

The invention relates to a prediction model for non-invasive quantitative evaluation of postoperative concurrent pancreatic fistula risk before pancreatic resection, and belongs to the technical field of medical imaging. According to the invention, a real image obtained in clinical practice is put into an artificial intelligence end, and ultrasonic multi-mode and preoperative various pancreatic fistula related indexes are combined; the method also comprises deeply mining image omics characteristic information in an image by using an AI algorithm, comprehensively evaluating, screening, weighting and comprehensively calculating the image omics characteristic information, extracting useful information, and establishing a diagnosis and treatment model for artificial intelligence prediction of postoperative pancreatic fistula in combination with various preoperative characteristics of a patient and related laboratory examination and image examination results. Starting from ultrasonic elastic quantification, the problem that the pancreas texture cannot be objectively evaluated before a pancreas resection operation in the past is solved, and non-invasive quantification is conducted on the pancreas texture; meanwhile, an artificial intelligence machine learning method is introduced, the problem that a large amount of information cannot be processed in real time during manual image analysis is solved, and the effectiveness and accuracy of a prediction model are maximized.

Description

technical field [0001] The invention relates to a prediction model for non-invasive quantitative evaluation of the risk of pancreatic fistula after pancreatectomy, belonging to the technical field of medical imaging. Background technique [0002] Pancreatic fistula (Pancreatic Fistula) is one of the most serious complications after acute pancreatitis, chronic pancreatitis, abdominal surgery (especially pancreatectomy) and abdominal trauma. Pancreatic juice leaving the normal outflow tract can accumulate in the abdominal cavity and cause necrosis of surrounding tissues, and then secondary infection. Infection can accelerate the activation of pancreatic enzymes and strengthen the digestion and corrosion of pancreatic juice. The erosion of the gastrointestinal tract by pancreatic juice can cause bleeding and internal fistula in the stomach, small intestine, colon, etc., and if the blood vessels are eroded, it can cause fatal massive hemorrhage. For patients with poor general c...

Problems solved by technology

However, at present, there is still no objective and effective index for the risk assessment of pancreatic fistula after pancreatectomy, and more often it relies on the experience judgment of clinicians, or the subjective evaluation of the texture of the pancreas by palpation of the pancreas during laparotomy. Judgment, not only prone to inter-observer differences, difficult to quantify results, but also lacks the possibility of preoperative prediction
