End-to-end anastomosis refers to a surgical procedure that restores function by anastomosing the severed ends of the lumen, and the recovery time for end-to-end anastomosis varies from site to site. In case of intestinal telangiectomy, the recovery time is about 10 days; in case of vascular telangiectomy, the recovery time is shorter and it usually takes about 7 days to recover; in case of ureteral telangiectomy, the recovery time is longer and it usually takes about 20 days.
