A method for testing for leaks of an anastomosis of a bowel, the method comprising:
- inserting an outlet of a delivery device into a lumen of the anastomosis;
- delivering a sufficient amount of an acid and a sufficient amount of a base to the bowel;
- producing a gaseous foam when the acid and the base enter the bowel to distend the bowel;
- evaluating if there is a leak by the presence or absence of gaseous foam outside of the anastomosis;
- and
- retracting the outlet of the delivery device from the lumen of the anastomosis.
