An endoscope was equipped with a saline-filled latex rubber balloon at its tip to displace contaminating blood, bile, or gastric contents during operative portoscopy, biliary endoscopy, or upper gastrointestinal endoscopy. A fiber with its tip inside the balloon transmitted energy from an Nd:YAG laser for coagulation of tumors in one bile duct cancer, in six portal vein growths from primary liver cancers, and in a superficially growing stomach cancer. The balloon increased the precision of irradiation by making lesions easier to identify through displacement of bile or blood and by keeping the fiber tip at a fixed position relative to the lesion. The technique, basic experimental studies, and clinical experiences are reported.
一种内窥镜在其顶端装有一个充满盐水的乳胶橡胶球囊，以便在手术性腹腔镜检查、胆道内窥镜检查或上消化道内窥镜检查期间排出污染的血液、胆汁或胃内容物。一根顶端位于球囊内的光纤传输来自钕钇铝石榴石激光的能量，用于凝固一例胆管癌、六例原发性肝癌门静脉生长灶及一例浅表生长型胃癌中的肿瘤。球囊通过使胆汁或血液移位从而更易于识别病变，并通过使光纤顶端相对于病变保持固定位置，提高了照射的精度。本文报告了该技术、基础实验研究及临床经验。
