概括
肠道移植为肠道衰竭患者提供了显著的好处. 在2023年,发生了95次移植,存活率和风险各不相同,特别是那些需要肝肠联合移植的人.
科学领域:
- 胃肠道学和肝病学
- 移植医学 移植医学
- 手术瘤学手术瘤学
背景情况:
- 肠道移植是肠道衰竭的重要治疗方法,通常是由于长期的肠道营养并发症或腹部灾难造成的.
- 尽管其关键作用,肠子移植很少进行,突出显示需要继续研究和改进结果.
- 近年来,对肠道移植的需求,特别是在成年人群中,一直在稳步增加.
研究的目的:
- 分析2023年肠移植的趋势,结果和并发症.
- 为了比较没有肝脏的肠和肠与肝脏移植之间的移植存活率和患者死亡率.
- 在不同的移植情景中评估急性排斥和移植后淋巴增殖障碍 (PTLD) 的发生率.
主要方法:
- 从2023年开始对肠道移植数据的回顾性分析,包括等待名单的增加,执行的程序和患者人口统计数据.
- 评估成人和儿科接受者1年和5年的移植存活率,按移植类型分层 (有或没有肝脏).
- 对等待名单上的死亡率和急性排斥和PTLD的发生率的分析.
主要成果:
- 在2023年,135名候选人被添加到等待名单上,95例肠道移植手术进行,其中33例为儿科接受者.
- 移植存活率有所不同:无肝肠移植显示1年存活率为78.3% (成人) 和76.1% (儿科),而有肝肠移植显示57.8% (成人) 和81.1% (儿科).
- 在第一年内,约20%的患者出现了急性排斥. 5年的PTLD发病率在没有肝脏的肠道 (11.5%) 和有肝脏的肠道 (2.5%) 接受者中较高.
结论:
- 肠道移植仍然是一个关键的治疗方法,但结果根据肝脏是否包括在内有显著差异.
- 虽然等待列表死亡率在没有肝脏的肠道移植中很低,但在等待肠与肝脏移植的人中,死亡率超过10%.
- 长期的移植存活率和并发症率需要持续的研究,特别是考虑到肠道康复的进步和不断增长的成年接受者池.

Anatomy of the Intestines
71.2K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
304
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Assessment of the Gastrointestinal System I: Subjective Data
132
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Inflammatory Bowel Disease V: Surgical Management
101
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.
Here are some common surgical interventions for IBD:

Renewal of Intestinal Stem Cells
2.5K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
38
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
