I need to measure the tensile strength of intestinal anastomosis but due to large sample size it is not possible to carry out the procedure immediately after sampling or within a few hours following sampling. I have previously frozen skin samples for the same purpose. I would like to know if it is also possible to freeze intestinal samples for later analysis or not? Also does anyone know whether anastomosis sutures should be removed prior to tensile measurement like skin sutures or not? Thank you in advance.
