A ligating instrument includes a handle for securing a proximal end of a ligating device externally of the body with one hand, the ligating device defining a lumen for passage therethrough of a length of ligature material formed with a ligature loop for being disposed externally of a distal end of the ligating device to be positioned around anatomical tissue to be ligated within the body, and an operating member coupled with the ligature material for being manually moved with the same hand as that securing the ligating device proximal end to pull the ligature material through the ligating device to form a ligature with the ligature loop in the anatomical tissue. A method of ligating tissue in endoscopic operative procedures includes the steps of securing a proximal end of a ligating instrument externally of the body with one hand, introducing a distal end of the ligating instrument at a surgical site in the body through a portal formed in tissue of the body, placing a length of ligature material carried by the ligating instrument around anatomical tissue to be ligated, moving an operating member of the ligating instrument with the same hand as that securing the proximal end to pull the ligature material through the ligating instrument to tighten the ligature material around the anatomical tissue to form a ligature and actuating a cutter of the ligating instrument to cut the ligature material away from the ligature.
