We described for the first time the contrast enhancement of a giant fibrovascular esophageal polyp using ultrasound contrast agent, Sonovue® (Bracco, Milan, Italy) during echoendoscopy. Fine Doppler ...
We describe a patient with a giant Brunner's gland hamartoma in the duodenum who was safely treated by endoscopic mucosal resection (EMR). A 64-year-old woman visited our hospital for a workup of seve...
Transoral resection of Zenker's diverticulum (TORD) was first reported in 2010. We present results for our modified approach to transoral resection (MTORD)-full-thickness cricopharyngeal myectomy, di...
To analyse the efficacy and safety of two standard methods of endoscopic mucosal resection (EMR) for large non-pedunculated colorectal polyps, We will compare submucosal injection-assisted...
This study compares different approaches to endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (≥20mm) in a 2 x 2 randomized design. The first randomization w...
This clinical trial is being conducted to compare the efficacy and safety of two standard methods of polypectomy，Conventional Endoscopic Mucosal Resection（EMR）and Underwater Endoscop...
This study evaluates the efficacy of small colorectal polyp removal using cold endoscopic mucosal resection with hot endoscopic mucosal resection. Half of the participants will receive col...
Randomized, comparative and prospective study between Conventional Endoscopic Mucosal Resection for the removal of flat or sessile colorectal lesions without previous attempt to resection.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
Surgical resection of the VULVA.
Surgical removal or resection of the CERVIX UTERI.
The local implantation of tumor cells by contamination of instruments and surgical equipment during and after surgical resection, resulting in local growth of the cells and tumor formation.
Multinucleated cells (fused macrophages) seen in granulomatous inflammations such as tuberculosis, syphilis, sarcoidosis, and deep fungal infections. They resemble foreign-body giant cells (GIANT CELLS, FOREIGN BODY) but Langhans giant cells contain less chromatin and their nuclei are arranged peripherally in a horseshoe-shaped pattern. Langhans giant cells occur frequently in delayed hypersensitivity.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
