The appearance on computed tomographic (CT) scans of the upper abdomen after partial hepatectomy is complex. The findings expected at CT should not be confused with those of surgical complications, such as abscess, biloma, or hematoma. The findings on CT scans and the records of 17 patients who had undergone partial hepatectomy for malignancy were reviewed. Operations included wedge resection, left medial and lateral segmentectomies, left lobectomy, right subsegmentectomy, right lobectomy, and extended right lobectomy (trisegmentectomy). When partial hepatectomy had been performed with no complications, findings at CT included a small region of low attenuation at the surgical margin, probably due to transient accumulation of blood and bile; a right pleural effusion; extraluminal gas; shift of abdominal organs; hepatic regeneration; and fat attenuation at the resection margin representing the omental patch placed at surgery. Findings associated with surgical complications--such as abscess, biloma, and hematoma--included large or high-attenuation perihepatic and subphrenic fluid collections that did not conform to the resection margin.
部分肝切除术后上腹部计算机断层扫描（CT）的表现较为复杂。CT上预期的表现不应与手术并发症（如脓肿、胆汁瘤或血肿）的表现相混淆。回顾了17例因恶性肿瘤接受部分肝切除术患者的CT扫描结果及记录。手术包括楔形切除术、左内侧和外侧段切除术、左叶切除术、右亚段切除术、右叶切除术和扩大右叶切除术（三段切除术）。当部分肝切除术无并发症时，CT表现包括手术边缘的小片状低密度区，可能是由于血液和胆汁的短暂积聚；右侧胸腔积液；腔外气体；腹部器官移位；肝脏再生；以及切除边缘的脂肪密度影，代表手术时放置的网膜补片。与手术并发症（如脓肿、胆汁瘤和血肿）相关的表现包括不符合切除边缘的肝周和膈下大的或高密度的液性聚集区。
