A 44 year-old man visited our hospital in January 2003, because of positive fecal occult blood test (FOB) . We detected multiple angioectasia in the transverse colon by total colonoscopy and diagnosed this lesion to be the cause of FOB positive. The lesions were treated by argon plasma coagulation with normal saline injection (NS-APC) . This technique is much safer than the usual APC procedure. The treatment was performed in the outpatient clinic without any complication, and no lesions were left 4 months later. APC-NS is useful treatment and safety technique for angioectasia of the colon.
