Passage: Rubber band ligation is typically recommended as the first-line treatment in those with grade 1 to 3 disease. It is a procedure in which elastic bands are applied onto an internal hemorrhoid at least 1 cm above the pectinate line to cut off its blood supply. Within 5–7 days, the withered hemorrhoid falls off. If the band is placed too close to the pectinate line, intense pain results immediately afterwards. Cure rate has been found to be about 87% with a complication rate of up to 3%.

Question: What is the complication rate?
3%
