The preoperative cholescintigrams of 16 patients with subacute or chronic gallbladder (GB) perforation demonstrated at surgery were reviewed, and the scintigraphic findings were characterized. Persistent GB nonvisualization was found in each study. Additional findings included a band of increased pericholecystic hepatic activity (PCHA) (n = 7) and/or a photopenic region in the GB fossa (n = 7). PCHA and photopenic region findings, when visualized, were most commonly associated with a subacute localized perforation with pericholecystic abscess formation. However, the sensitivity of each of these findings was only 44%. Cholescintigrams did not directly demonstrate the perforation site in any patient. Although the presence of the PCHA sign and/or GB fossa photopenic region appears to identify a subgroup of patients at increased risk for perforation, cholescintigraphy is relatively insensitive for detection of subacute or chronic GB perforation.
对16例手术中证实为亚急性或慢性胆囊穿孔患者的术前胆囊闪烁扫描图像进行回顾，并对闪烁扫描结果进行特征描述。每项研究均发现胆囊持续不显影。其他表现包括胆囊周围肝组织活性增强带（PCHA）（7例）和/或胆囊窝放射性缺损区（7例）。PCHA和放射性缺损区表现若能显影，最常见于伴有胆囊周围脓肿形成的亚急性局限性穿孔。然而，这些表现的敏感性仅为44%。胆囊闪烁扫描未在任何患者中直接显示穿孔部位。虽然PCHA征和/或胆囊窝放射性缺损区的出现似乎可识别出穿孔风险增加的亚组患者，但胆囊闪烁扫描对亚急性或慢性胆囊穿孔的检测相对不敏感。
