概括

使用双极软凝血模式 (NIRBS) 的非注射切除提供了一种可行的内镜方法来切除结肠直肠聚. 这种技术可以实现显著的粘膜下组织切除深度,与传统方法相比,无论内镜学家的经验如何.

科学领域:

胃肠病学胃肠病学
内視鏡外科手術內視鏡外科手術
结肠直肠癌预防预防

背景情况:

结肠直肠聚切除对于降低癌症死亡率至关重要.
一种新的技术,使用双极软凝血模式 (NIRBS) 的非注射切除,已经开发出来.
评估NIRBS的可行性和有效性至关重要.

研究的目的:

为了比较NIRBS的切除深度与冷陷多角切除术 (CSP) 和常规内镜粘膜切除术 (CEMR).
评估NIRBS用于结直肠多切除的可行性.

主要方法:

一项比较研究涉及95个结直肠多 (6-9毫米) 用NIRBS,CSP或CEMR治疗.
对切除的粘膜下组织厚度的分析.
包括专家和非专家内镜师的数据.

主要成果:

与CSP (21.4%) 不同的是,NIRBS和CEMR标本经常含有亚粘膜组织 (97.9%和100.0%).
在NIRBS (1,125微米) 和CEMR (1,167微米) 中,下粘膜组织的中位厚度显著,超过CSP (0微米).
NIRBS实现了1,140微米 (专家) 和1,017微米 (非专家) 的中位厚度,证明了一致的深度.

结论:

NIRBS始终实现了超过1000微米的下切除深度.
该技术的有效性独立于内镜师的经验.
NIRBS为结直肠多瘤提供了一个可行的内镜切除选项,包括那些早期癌症.

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic 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...
