内镜粘膜切除和内窥镜粘膜粘膜解剖:用于切除GI粘膜肿瘤的微创技术
Major advances in the development of endoscopic devices and techniques over the past fifteen years have introduced endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) as standard of care for the safe and effective removal and/or definitive staging of mucosal lesions of the esophagus, stomach, duodenum and colon, often eliminating major surgery as first-line management. Gastroenterologists at118金宝搏抽水Penn State Health Milton S. Hershey Medical Center包含亚伯拉罕马修,MD那马修·梅奥医学博士, 和Charles Dye, MD,已成为这些技术的领先临床医生和活跃的研究人员,每年执行几百个EMR程序。Mathew解释说:“EMR是这些技术更广泛地用于去除较小的肿瘤或病变[<2.5cm]。使用EMR,正常盐水或羟基丙基甲基纤维素,稀肾上腺素和亚甲基蓝色注入肿瘤下粘膜空间的关键区域,策略性地定位肿瘤并将其与肠壁分离;然后可以将肿瘤较小的热或机械损伤的风险较低。通过ESD,外科医生采用更具侵略性的去除较大,更侵入性肿瘤的侵略性,使用专门的装置隧道进入粘膜膜,以将肿瘤堵塞划分。切口用缝合线或夹子内窥镜闭合。“
通过ESD切除过程中的结肠质量病变。
Moyer注意到EMR和ESD的好处在高批量中心进行时,具有正确的设备和程序量的合适团队,越来越大的风险;然而,可能发生并发症,并且应该向患者解释。“并发症包括出血,其出现在五到10%的病例中,较低的穿孔风险(1%EMR,2%至5%ESD)。不完全去除异常组织是EMR(1至11%)和ESD(1%)的长期复杂性。“
在筛查程序期间,病变失败的病变患者可能更大的风险。这支球队强烈建议推荐医生,以避免试图去除任何损害,这些病变在筛查程序期间不适合完全去除。染料解释说:“随着病变去除的尝试失败,所得到的炎症反应可以粘附剩余的异常组织对肌肉馅目,使随后的内窥镜去除困难并提高主要手术的潜力。”建议参考医生标记目标病变,如有必要,从周边获得活检,并将患者提交到三级小心,以便完成,并且最小化风险。
Patients typically undergo routine surveillance endoscopy at three or six months and one year after. Mathew notes, “Minimally invasive procedures like EMR and ESD can make a real difference in the life of a patient. They can return to normal activities usually the next day with a very low risk of any complication or lesion recurrence.”
Indications for EMR or ESD
- Mucosal lesions of the esophagus (cancerous or potentially cancerous) including lesions within Barrett’s esophagus and short-segment Barrett’s esophagus with dysplasia
- 胃粘膜病变
- 十二指肠病变,包括需要ERCP辅助的安培切除术的安瓿病变
- Adenomatous colon and rectal lesions not amendable to safe or complete removal during screening colonoscopy
- 有限的胃和直肠毒细胞瘤
- 选择粘膜病变
