腹疝（VHs）是前腹壁的异常开口，是手术干预的常见副作用。VH修复是世界范围内普通外科医生最常用的手术，但VH修复效果并不特别令人鼓舞（复发率高达43%）。各种开放和腹腔镜技术可用于疝修补，具体使用的技术最终取决于外科医生的偏好和经验。尽管对VH患者进行了常规的计算机断层扫描（CT），但很少有定量信息可用于指导选择特定方法和/或优化患者特异性治疗。从轶事访谈来看，VH修复手术的成功与疝的大小、位置和累及二级结构有关。在此，我们提出了一种图像标记方案来分割前腹部区域，为提取生物标志物和评估治疗效果提供几何基础。根据常规的临床CT数据，我们能够识别腹壁的内外表面和突出的体积。这是第一次在腹部CT上对这些结构进行量化的正式报告。在4例疑似VH患者（3例最终诊断为VH， 1例未诊断为VH）中评估了该方案的内部和内部可重复性。所有结构的平均表面距离均小于2mm。
Ventral hernias (VHs) are abnormal openings in the anterior abdominal wall that are common side effects of surgical intervention. Repair of VHs is the most commonly performed procedure by general surgeons worldwide, but VH repair outcomes are not particularly encouraging (with recurrence rates up to 43%). A variety of open and laparoscopic techniques are available for hernia repair, and the specific technique used is ultimately driven by surgeon preference and experience. Despite routine acquisition of computed tomography (CT) for VH patients, little quantitative information is available on which to guide selection of a particular approach and/or optimize patient-specific treatment. From anecdotal interviews, the success of VH repair procedures correlates with hernia size, location, and involvement of secondary structures. Herein, we propose an image labeling protocol to segment the anterior abdominal area to provide a geometric basis with which to derive biomarkers and evaluate treatment efficacy. Based on routine clinical CT data, we are able to identify inner and outer surfaces of the abdominal walls and the herniated volume. This is the first formal presentation of a protocol to quantify these structures on abdominal CT. The intra- and inter rater reproducibilities of this protocol are evaluated on 4 patients with suspected VH (3 patients were ultimately diagnosed with VH while 1 was not). Mean surfaces distances of less than 2mm were achieved for all structures.
