腹腔镜胃袖状切除术前及术后胃容积的测定方法及意义

Measurement of Gastric Volume Before and After Laparoscopic Sleeve Gastrectomy

腹腔镜胃袖状切除术(laparoscopic sleeve gastrectomy,LSG)作为一种确定的、单独的治疗病态肥胖的手术方式,在减少体重指数(body mass index,BMI)、多余体重减少百分比(percent excess weight loss,%EWL)以及改善肥胖相关并发症等方面取得良好效果,但手术治疗肥胖症的机制仍不明确。作为一种限制性手术方式,LSG最重要的机制可能是减少胃的容积来限制食物的摄入。因此,测量胃的容积是实现术后最佳减重效果不可缺少的技术。目前测定胃容积方法主要有影像学测量法和术中直接测量法。影像学方法包括上消化道造影、CT三维重建、MRI和核素扫描测量。本文将LSG术前、术后胃容积的测定方法作一综述。

Laparoscopic sleeve gastrectomy （LSG） as a sole and definitive bariatric surgery has achieved well results in terms of decreasing the body mass index （BMI） and percentage of excess weight loss （ % EWL）, therefore reducing the obesity-related complications, but the mechanism remains unclear. As a restrictive surgical procedure, the most important mechanism of LSG might be the reduction of the volume of the stomach resulting in a limited food intake. Therefore, to achieve the best weight loss after surgery, measuring the gastric volume is an indispensable technology. Currently, gastric capacity measurement methods include imaging measurements and intraoperative direct measurement. Imaging ods include upper gastrointestinal radiography, CT threedimensional reconstruction, Mill and radionuelide scanning, with each having its advantages and disadvantages. In this article, the measurement methods of gastric capacity before and after LSG were reviewed.
