摘要

背景/目的：体成分在预测急性胰腺炎（AP）严重程度方面的临床应用尚不清楚。我们的目的是利用人工智能（AI）测量身体成分来预测住院患者的严重AP。方法：我们对2018年在三家三级医疗中心住院的AP患者进行了回顾性研究。纳入入院时腹部计算机断层扫描（CT）成像的患者。采用全自动、有效的腹部分割算法进行体成分分析。主要结局是严重AP，根据修订的亚特兰大分类定义为持续的单器官或多器官衰竭。结果：共纳入352例患者。严重AP 35例（9.9%）。在多变量分析中，调整男性性别和AP首次发作后，肌间脂肪组织（IMAT）与严重AP相关，OR = 1.06 / 5 cm2, p = 0.0207。皮下脂肪组织（SAT）面积接近显著性，OR = 1.05, p = 0.17。内脏脂肪组织（VAT）和骨骼肌（SM）均与严重AP无关。在未调整的分析中，肥胖患者较高的SM与严重AP相关（中度和轻度分别为86.7 vs 75.1和70.3 cm2, p = 0.009）。结论：在这项使用AI测量身体成分的多位点回顾性研究中，我们发现IMAT升高与严重AP相关。尽管SAT对严重AP不显著，但其接近统计学意义。VAT和SM均不显著。在更大的前瞻性研究中进一步研究可能是有益的。

Measurement of adipose body composition using an artificial intelligence-based CT Protocol and its association with severe acute pancreatitis in hospitalized patients

Background/Objectives

The clinical utility of body composition in predicting the severity of acute pancreatitis (AP) remains unclear. We aimed to measure body composition using artificial intelligence (AI) to predict severe AP in hospitalized patients.

Methods

We performed a retrospective study of patients hospitalized with AP at three tertiary care centers in 2018. Patients with computer tomography (CT) imaging of the abdomen at admission were included. A fully automated and validated abdominal segmentation algorithm was used for body composition analysis. The primary outcome was severe AP, defined as having persistent single- or multi-organ failure as per the revised Atlanta classification.

Results

352 patients were included. Severe AP occurred in 35 patients (9.9%). In multivariable analysis, adjusting for male sex and first episode of AP, intermuscular adipose tissue (IMAT) was associated with severe AP, OR = 1.06 per 5 cm², p = 0.0207. Subcutaneous adipose tissue (SAT) area approached significance, OR = 1.05, p = 0.17. Neither visceral adipose tissue (VAT) nor skeletal muscle (SM) was associated with severe AP. In obese patients, a higher SM was associated with severe AP in unadjusted analysis (86.7 vs 75.1 and 70.3 cm² in moderate and mild, respectively p = 0.009).

Conclusion

In this multi-site retrospective study using AI to measure body composition, we found elevated IMAT to be associated with severe AP. Although SAT was non-significant for severe AP, it approached statistical significance. Neither VAT nor SM were significant. Further research in larger prospective studies may be beneficial.
