Endoscopic Biopsy Techniques in Barrett's Esophagus Patients

"* Using the turn-and-suction technique, the forceps cups are opened and the forceps is withdrawn against the tip of the endoscope. The tip is then directed toward the target ('turn'), and suction is applied ('suction') as the forceps is applied against the targeted mucosa and then closed.~* Endoscopists can obtain two biopsy specimens from a single passage of the conventional biopsy forceps instead of one. These techniques are called the 'double-biopsy method' and the 'single-biopsy method', respectively."
