It is vital the biopsy channel size of the endoscope is co-ordinated with compatible devices in order to obtain the best results during the procedure. The minimum biopsy channel diameter required is 2.8 mm and length of up to 150 cm. The outer diameter of the scope to be used must be from 8,5 mm up to 11,5 mm. Band ligation may not be effective when applied to small varices.
It is vital to ensure the understanding of the technical principles, clinical applications and associated risks with GI endoscopy as well as endoscopic banding before using this product. This product must only be used by or under direct supervision of physician thoroughly trained in therapeutic endoscopy as well as vessel banding.
Oesophageal ligators are not intended for ligation of varices below the gastro-oesophageal junction.
Banding should begin at the gastro-oesophageal junction and proceed up the oesophagus in an helicoidal manner, respecting a minimum of 2cm in between 2 ligatures. Passing the endoscope over an already ligated varices may dislodge the band from its position.
Routine endoscopic examination by the physician is recommended to confirm the diagnosis requiring treatment of oesophageal varices prior to assembling the Multiband Ligator.
