背景：肥胖患者胃食管区域的视野有限，常常因脂肪浸润导致肝脏肿大而加剧。术前缩小肝脏大小将有助于外科医生，特别是那些不习惯处理病态肥胖患者的外科医生。方法：50 名预约进行腹腔镜胃束带术的病态肥胖患者术前接受了为期 2 周的低能量流质饮食。在饮食开始时和饮食结束时（术前）对肝脏左叶进行超声测量并进行身体分析。将肝脏大小的变化与身体分析变化进行比较。结果：两周内肝脏大小显着减小，这与 BMI 和体重减轻相关。与脂肪减少没有相关性。术中没有遇到较大的肝左叶，也没有对任何术前成功减肥的患者造成任何问题。结论：术前限制膳食能量会减小肝脏的大小，并且可以通过相关的体重减轻准确预测。
Background: A limited view of the gastro-esophageal area in obese patients is often aggravated by an enlarged liver due to fatty infiltration. Preoperative decrease in liver size would help surgeons, particularly those not used to working with morbidly obese patients.Methods: 50 morbidly obese patients booked for laparoscopic gastric banding undertook a 2-week, preoperative low energy liquid diet. Ultrasound measurements of the left lobe of the liver and body analysis were undertaken at the start of the diet, and again at the conclusion of the diet (preoperatively). Changes in liver size were compared to body analysis changes.Results: There was a highly significant decrease in liver size in the 2 weeks, which correlated with BMI and weight loss. There was no correlation with fat loss. No large left lobe of the liver was encountered at surgery nor caused any problem in any patients with successful preoperative weight loss.Conclusions: Preoperative restriction of dietary energy will reduce liver size, and is accurately predicted by associated weight loss.
