Intestinal Perforation During Colonoscopy Reported with PENTAX Gas/Water Valve

Problems with the PENTAX endoscope were first identified when Australian health authorities reported the case of a 71 year-old man who suffered numerous intestinal perforations. Doctors were performing a routine colonoscopy procedure to remove polyps in his intestines. They were using a PENTAX endoscope with the OF-B194 Gas/Water Valve.

During the procedure, the man’s abdomen became severely swollen. The doctors realized that his intestines were filling with CO2, but they were unable to shut off the valve on the endoscope. After the endoscope was removed, doctors noticed that it was leaking CO2 that could not be turned off. The patients required intensive medical treatment for numerous, small intestinal perforations. He ultimately needed surgical excision of part of his intestines.

What is the PENTAX valve used for?

The OF-B194 Gas/Water Valve is a component that is used with the PENTAX GI Video Endoscope. The endoscope is a long, flexible tube with a video attached to the end. Doctors insert the endoscope into a patient’s mouth or anus to view inside the gastrointestinal system. During the procedure, doctors must inflate the intestines with CO2 so they can see part of the intestinal tract.

What’s the problem?

The problem is that the OF-B194 Gas/Water Valve may have been assembled improperly. During a medical procedure, it could leak CO2 and doctors may be unable to turn off the valve. This could lead to over-inflation of a patient’s intestines, with life-threatening complications:

  • Peritonitis (inflammation of tissue lining organs and inner wall of abdomen)
  • Perforations
  • Sepsis (whole-body inflammation caused by infection)
  • Bowel perforations requiring surgery
  • Death
