概括
laparoscopic 袖子胃切除术改变了肠道微生物组,影响了骨代谢. 微生物组成的变化与手术后骨的转化和损失增加相关,这表明肠道细菌和骨健康之间存在联系.
科学领域:
- 腹腔外科手术是什么意思
- 肠道微生物组研究研究
- 骨健康和新陈代谢
背景情况:
- 腹腔镜袖胃切除术 (LSG) 是一种常见的减肥手术,用于减肥和改善并发症.
- LSG可以对骨代谢产生负面影响,这是一个尚未完全理解的并发症.
- 肠道微生物组在骨健康中的作用是公认的,但在LSG的背景下尚未被探索.
研究的目的:
- 调查肠道微生物组变化和LSG后骨健康变化之间的关系.
- 为了确定特定的微生物或代谢因素影响骨代谢后LSG.
主要方法:
- 对23名患有严重肥胖的成年人进行了前性队列研究,接受了LSG.
- 骨健康评估和便样本采集手术前和后 (6个月).
- 用于肠道微生物组分析的16S rRNA基因测序和用于便短链脂肪酸 (SCFA) 的LC-MS/MS.
主要成果:
- LSG增加了骨循环标记 (CTx,P1NP) 和减少了股骨部 BMD.
- 在LSG后观察到Firmicutes类的减少.
- 肠道微生物组成 (β-多样性) 的更大变化与更高的P1NP和更大的骨损失相关.
- 与IGF-1水平相关的微生物丰富性/均性 (α-多样性) 的变化.
- 术后较低的丁酸盐度与较低的IGF-1和较高的CTx相关.
结论:
- 由LSG诱导的肠道微生物组变化可能会对骨结果产生负面影响.
- 微生物产生的丁酸盐及其对IGF-1的影响可能是关键机制,将肠道健康与LSG后骨健康联系起来.

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...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
