[A modified monopolar electrocoagulation probe for endoscopic treatment of gastrointestinal hemorrhage]

A modified monopolar electrocoagulation probe for endoscopic treatment of gastrointestinal bleedings in special situations is described. The tip of the active electrode may be moved foreward or drawn back into a teflon catheter. Thereby, blood clots are removed from the tip of the probe. The device is easy to use, reliable in emergency endoscopies and can be employed with conventional high-frequency diathermy instruments. The probe is inexpensive. 49 patients with active gastrointestinal bleedings according to Forrest Ib were treated. In 40/49 patients permanent hemostasis could be achieved. In 4/49 patients recurrent bleedings were controlled after repeated electro-coagulation. 4/49 patients needed elective operation, one patient emergency operation. Complications by application of the described monopolar electrocoagulation probe did not occur. The area of necrosis according to electrocoagulation was small.
