概括
腹腔外科手术患者经历了显著的骨矿物密度 (BMD) 损失在腹腔镜Roux-en-Y胃绕道 (LRYGB) 后五年. 低体重指数 (BMI) 的老年患者有更高的BMD加速下降风险.
科学领域:
- 内分泌学 在内分泌学.
- 代谢手术 代谢手术
- 骨健康 骨健康 骨健康
背景情况:
- 腹腔外科手术,包括腹腔镜Roux-en-Y胃绕道 (LRYGB),与骨矿物质密度 (BMD) 的降低有关.
- 对于LRYGB对脊椎 BMD 的长期影响需要进一步研究.
研究的目的:
- 为了评估长期的脊椎BMD和体重指数 (BMI) 在LRYGB之后的变化.
- 评估机会性定量CT (QCT) 在手术后监测BMD的有效性.
主要方法:
- 接受LRYGB治疗的62名患者在基线和手术后1,3年和5年通过机会性QCT测量了BMD和BMI.
- 统计分析包括单向ANOVA和ANCOVA,以评估随时间变化的BMD和BMI,以年龄和性别为共变量.
主要成果:
- 在LRYGB后的5年内,骨质量持续显著下降,与基线相比,在3年和5年显著下降.
- 体重指数在第一年内下降,稳定,并在第5年略有增加.
- 年龄和基线BMI是 BMD 损失的显著共变量,这表明老年,更瘦的患者的风险更高.
结论:
- 机会性QCT是一种可行的方法,用于跟踪LRYGB后的BMD变化.
- 在5年内,LRYGB会导致持续的骨质量减少.
- 低BMI的老年患者特别容易在LRYGB之后加速骨密度下降.

01:29Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
During an EGD, the endoscope can be used to:
01:26Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
