A prospective study was performed to determine the impact of preoperative assessment of estimated postoperative liver volume on surgical decision making for liver metastases from colorectal cancer. Assessment of estimated postoperative liver volume was performed before surgery in 25 patients. Mean estimated postoperative liver volume +/- standard deviation (SD) was 697 cm3 +/- 317 (range, 320-1,532 cm3). Mean relative estimated postoperative liver volume +/- SD was 51% +/- 16 (range, 20%-90%). In two patients, relative estimated postoperative liver volumes of less than 35% prevented resection. These two patients underwent preoperative portal vein embolization, which resulted in marked hypertrophy of the unembolized healthy part of the liver and subsequent safe resection. Before surgery, all patients had a relative estimated postoperative liver volume of greater than 35%, and no cases of postoperative liver failure occurred. The results demonstrated that assessment of estimated postoperative liver volume provides vital preoperative data for reducing the risk of postoperative liver failure.
进行了一项前瞻性研究，以确定术前评估预计术后肝体积对结直肠癌肝转移手术决策的影响。对25例患者在手术前进行了预计术后肝体积的评估。平均预计术后肝体积±标准差（SD）为697 cm³±317（范围为320 - 1532 cm³）。平均相对预计术后肝体积±SD为51%±16（范围为20% - 90%）。在两名患者中，相对预计术后肝体积小于35%导致无法进行切除。这两名患者接受了术前门静脉栓塞，结果未栓塞的健康肝脏部分出现明显肥大，随后得以安全切除。手术前，所有患者的相对预计术后肝体积均大于35%，且未发生术后肝衰竭病例。结果表明，预计术后肝体积的评估为降低术后肝衰竭风险提供了重要的术前数据。
