概括
袖子胃切除术 (SG) 后的大脑结构差异是未知的. 体重过多减轻 (EWL) 的患者表现出更好的白质完整性,这与更少的痛苦和暴饮暴食有关.
科学领域:
- 神经成像是一种神经成像.
- 腹部外科手术的结果
- 肥胖问题研究研究
背景情况:
- 在袖子胃切除术 (SG) 后,基于过量减肥 (EWL) 调查肥胖患者 (PwO) 的大脑结构差异.
- 在PwO中比较灰质体积 (GMV) 和白质 (WM) 完整性,在PwO中>50%的EWL,<50%的EWL,以及在没有先前减肥手术的情况下控制肥胖 (CwO).
研究的目的:
- 为了确定PWO中潜在的大脑结构差异,在SG后达到不同程度的EWL.
- 为了比较成功和不太成功的减肥组和对照组之间的GMV和WM完整性.
主要方法:
- 在62个PWO (24>50%EWL,18>50%EWL) 和20个CwO上进行1.5T磁共振扫描.
- 基于Voxel的形态测量和基于通道的空间统计,用于GMV和WM分析.
- 多重回归以关联结构和心理措施.
主要成果:
- 与其他组相比,>50%的EWL组的GMV损失显著降低,WM完整性更高.
- 在>50%的EWL组中,WM完整性和心理测量之间的正相关性 (较低的完整性与更高的痛苦,情绪失调,暴饮暴食有关).
结论:
- 有限的GMV变化,但在PwO之间观察到广泛的WM微结构差异,在SG后高EWL与低EWL.
- 微观结构上的WM差异可能表明白质在PWO中对代谢功能障碍的脆弱性更高.

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
