title: Colonoscopic snare polypectomy: analysis of 1485 resections comparing two types of current.
abstract: The complications related to 1485 colonic snare polypectomies were analyzed according to the type of current which was used for resection. From January 1982 to August 1986 (period 1), blended current was used in 758 snare polypectomies, while continuous coagulation current was applied in 727 polypectomies from September 1986 to October 1989 (period 2). The incidence of complications observed in the entire series was low, consisting of 0.26% perforations and 0.9% major hemorrhages. There were no deaths in this series. Twelve of 14 hemorrhages occurred after resection of polyps larger than 1 cm. Although the incidence of complications was not statistically different in the two groups, there was a significant difference in the timing of hemorrhages. All of the major hemorrhages were immediate (eight) when the blended current was used, but delayed (six; from 2 to 8 days after polyp resection), when pure coagulation current was applied.
