Summary

One-year recurrence rate of acute pancreatitis at about 20%. 36% of the patients with recurrent acute pancreatitis will develop into chronic pancreatitis. In addition to negative impact on patient's quality of life, chronic pancreatitis is also associated with the occurrence of pancreatic cancer. The etiology of recurrent acute pancreatitis (RAP) can be divided into mechanical obstructive factors (e.g. cholelithiasis, cholestasis), metabolic abnormality and toxic substance factors (e.g. hyperlipidemia and alcoholism), and other or idiopathic factors. At present, the diagnosis and treatment of RAP remains highly challenging. Early identification and intervention on risk factors of recurrence will be effective in reducing incidence and improving prognosis.

Contrast-enhanced Computed Tomography (CT) can not only provide more imaging information and further assess the severity of acute pancreatitis, but also aid in the differentiation of other diseases associated with acute abdominal pain. In addition, radiomics based on raw radiographic data has become a research hotspot in recent years. The purpose of this study is to establish and validate a deep learning model based on high concentration iopromide-enhanced abdominal CT images which is designed to predict the recurrence of pancreatitis in patients with first episode of pancreatitis within the 1-year follow-up period.

Radiomics Model

A total of 694 consecutive eligible patients with first episode of "acute pancreatitis" that recommended for iopromide 370 mgI/ml enhanced pancreatic CT scan within 14 days after onset of symptoms (the sample size ratio of training set: test set: validation set is 5:2:3) will be sequentially enrolled at 10 sites (This study is observational in nature. The routine enhanced pancreatic CT protocol at all selected sites is similar or equivalent to that used in the PI site in the study). Relevant clinical information of the enrolled subjects is collected. Radiomics features are extracted from the selected regions of interest on pancreatic CT images and classified. The subjects are followed up for 12 months and divided into recurrent group and non-recurrent group according to the first recurrence status.
