Hemorrhoids. Measuring the constrictive force of rubber bands.
In ligating hemorrhoids with rubber bands, weaker constrictive force lessens liability to subsequent bleeding but increases that for venous block without complete arterial block. A method applicable in the office is described to assess this force. Thirteen samples of rubber bands tested exhibited very wide differences of this force and also of hysteresis. Some attributes of the desirable rubber band are submitted.
