除了标准的内窥镜手术, including endoscopic retrograde cholangiopancreatography (ERCP), 上消化道内窥镜和乙状结肠镜, 加州大学旧金山分校健康's digestive disorder specialists offer advanced endoscopic procedures. 在很多情况下, these techniques provide improved options for the treatment and diagnosis of a variety of digestive disorders affecting the GI tract, 包括减肥.
高级内窥镜手术
Endoscopic refers to the use of an instrument called an endoscope — a thin, flexible tube with a tiny video camera and light on the end. The high-quality picture from the endoscope is shown on a television monitor, providing a clear and 消化道的详细视图. All endoscopic procedures are performed by one of our gastroenterologists who are experts in digestive disorders. We specialize in the following advanced endoscopic procedures.
小肠镜
小肠镜 allows for the examination of a large portion of the upper small bowel via the use of an extended length endoscope. It is about two and a half times as long as a standard upper endoscope. It is typically used to identify and treat potential sources of bleeding in patients whose previous endoscopy and colonoscopy results have been normal. 除了, enteroscopy may be performed in patients with suspected mucosal disease of the small bowel, whose tissues biopsies are obtained during the time of the procedure.
食管支架
食管支架, 也叫肠内支架置入术, is performed for patients with obstruction of the digestive tract. 通常, 这些支架放置在食道中, colon or the upper small bowel to relieve the obstruction caused by esophageal, 结肠癌和胰十二指肠癌. 支架通常放置在晚期, 不治之症才能帮助他们继续吃饭. 除了, in patients with colon cancer who are candidates for surgery, it may allow for improved preoperative cleansing of the colon. This has the potential to allow for performing the excision of the cancer and reattachment of the colon with a single operation, 而不是两个步骤.

内镜治疗
We offer a variety of endoscopic therapies for the treatment of gastrointestinal bleeding. 这些包括:
- Esophageal banding and sclerotherapy for variceal bleeding
- Bicap cautery, "endo-clipping" or injection therapy with epinephrine for ulcer bleeding
- Bicep-cautery or for the treatment of vascular ectasia of the stomach, colon or rectum
- Hemorrhoidal sclerotherapy for patients with hemorrhoidal bleeding
Many large polyps or early cancers that previously required a surgical approach may now be treated endoscopically. These improved techniques provide an alternative to surgery when noninvasive lesions are identified.
内镜超声检查
内镜超声检查 (EUS) is a method of combining endoscopy and ultrasound imaging technologies to obtain high-quality images of the digestive tract and its adjacent structures. 内窥镜是一种仪器, flexible tube with a tiny video camera and light on the end, 这提供了一个清晰的, 消化道的详细视图. Ultrasound is an imaging technique that uses sound waves to produce pictures.
在内镜超声检查中, a special endoscope is used that has an ultrasound processor on its tip, 称为EUS镜, 或echoendoscope. These instruments allow examination of both the lining of your digestive tract with the endoscope, but also of the wall of the tract and its surrounding structures such as the liver, 胰腺, 胆管和淋巴结. 还可以看到许多其他结构. 因为这些独特的功能, EUS can sometimes detect abnormalities or obtain information other imaging tests cannot. EUS手术可以通过口腔进行, 称为上EUS, 或者通过直肠, 称为直肠或下部EUS.
EUS is primarily used to detect suspected cancers and evaluate how far a previously diagnosed cancer has spread in order to determine a patient's appropriate treatment plan. The process of determining the extent to which a cancer has spread is called staging. EUS is used to stage cancers of the esophagus, stomach, 胰腺 and rectum. If cancer has spread to adjacent lymph nodes and blood vessels, it can be determined by the imaging and fine-needle aspiration capabilities of EUS. EUS给出部分, 但不完全, information regarding the spread of these tumors to adjacent organs due to its limited depth of penetration. 然而, recent imaging enhancements allow for greater evaluation of adjacent organs than previously possible.
EUS的其他用途包括:
- Identifying the nature of "lumps" and "bumps" seen on a previous endoscopic exam. These bumps may represent an adjacent structure compressing the digestive tract or represent a mass or fluid collection within the wall of the digestive tract.
- 评估胰腺和胆管疾病, the tubes that drain bile from your liver and gall bladder. EUS很容易看到胆管, 胰腺可以检查肿块, 暗示慢性炎症的囊肿或变化.
- Evaluating patients with fecal incontinence and stage lung cancers as well as evaluating for clots in the vessels of the abdomen with the use of a process known as Doppler ultrasound imagining.
