biopsy forceps

The carcinoids were removed by hot biopsy forceps or electrocautery snare.

The mucosal surface was then pinned out and biopsied with colonoscopy biopsy forceps.

Ancillary equipment - endoscopy biopsy forceps, snares, injectors (see Instruments used in gastroenterology).

In one patient the lesion was destroyed by hot biopsy forceps and further biopsy specimens were free from carcinoid infiltration.

Reports on the clinical use of endobiliary biopsy forceps are limited and their place in the investigation of biliary strictures remains to be established.

The endoscopes were sterilised after each examination according to local standards; the biopsy forceps were sterilised by autoclaving.

Biopsy specimens were taken with new rat toothed flexible head biopsy forceps (Olympus FB-40Q).

Endoscopic polypectomy has been carried out since the early 1970s by both endoscopic snare removal and fulguration of polyps with hot biopsy forceps.

A duodenal ulcer was defined as a mucosal defect of greater than 5 mm in diameter, measured by comparison with open biopsy forceps of known size.

The polyps are routinely removed at the time of colonoscopy either with a polypectomy snare (first description by P. Deyhle, Germany, 1970) or with biopsy forceps.

As there may be infiltration of the submucosa, larger biopsy forceps, endoscopic ultrasound guided biopsy, endoscopic submucosal resection, or laparotomy may be required to obtain tissue.

A biopsy forceps, a device used to collect a small tissue sample for cancer tests, is exempt from reviews, but Ms. Torrente said studies had shown that forceps were particularly difficult to clean.

Negative endoscopic biopsies can, to some extent, be explained by the specific growth pattern of the tumour; primary lymphoma arises in submucosal lymphoid patches, hence not within easy reach of biopsy forceps.

Tissue specimens were taken with biopsy forceps (FB-25K, Olympus, Tokyo, Japan) from the border of the gastric ulcer, and 5-10 cm away from the ulcer in the endoscopically normal gastric mucosa.

Multiple types of micro instrumentation are available, including grasping forceps, biopsy forceps, drills, needles, laser fibers, and lithotripters (although the last is currently unavailable in the US pending U.S. Food and Drug Administration approval).
