MONTVALE, N.J., Oct. 31, 2013 /PRNewswire/ -- On September 16, 2013 PENTAX
Medical Company  initiated a voluntary nationwide recall of 76 PENTAX Gas/
Water Valves, model OF-B194. The valves were offered as a separate purchase
for use with PENTAX GI Video Endoscopes (90i/90k series and i10/k10 series).
The OF-B194 Valve has been found to have a manufacturing defect which may
prevent users from turning off the CO2 gas flow during an endoscopic procedure
with the potential for serious hazard to the patient, including: peritonitis,
perforations, sepsis, death, and bowel perforations requiring surgical repair.

Customers who have OF-B194 PENTAX Gas/ Water Valves have been advised to
immediately examine their inventory and quarantine and stop using the product
subject to the recall.

Recalled  OF-B194 Gas/ Water Valves were  manufactured and distributed from
August 2009 through July 2013. A total of 704 valves were distributed
worldwide in the following regions: Europe/Middle East/Africa (EMEA) 300
valves, Asia Pacific (APAC) 278 valves, 24 valves in Japan, 26 valves in
Canada and 76 valves in the United States. All units distributed in the United
States and Worldwide have been recalled.

Products can be identified by the model number (OF-B194) stamped on the valve.
Corrected valves have a circle before the model number (O OF-B194).

PENTAX Medical Company  voluntarily recalled the OF-B194 Valve after becoming
aware of  a report to the Australia regulatory authority: A 74-year-old male
patient admitted for routine Colonoscopy. Polypectomy performed in sigmoid on
advancing to the caecum. Reached right side of colon and noticed Petechiae
(discolouration due to minute haemorrhage within tissue). At this stage
distended abdomen was noted. Suction reported to not be effective in reducing
the distension. An alternative CO2 valve changed in an attempt to halt the
flow of CO2 into the bowel. Upon withdrawal of the colonoscope, CO2 was noted
to be flowing from the scope despite valve not being depressed, which is
irregular. Patient had abdominal x-ray performed in recovery, a number of
small perforations detected. Patient returned to operating theatre, right
Hemicolectomy performed. Patient transferred to ICU.

Our investigation into the event concluded there is a possibility that some
valves may have been incorrectly assembled. No injuries have been reported in
the United States to date. PENTAX Medical Company has notified the FDA of this

PENTAX Medical Company distributed the product to Medical Facilities and
PENTAX Sales Representatives/ Field Support Staff in the United States. All
affected Medical Facilities in the United States have been notified of the
action, have responded, and replacement OF-B194 Valves have been provided by
PENTAX Medical Company.
