Inguinal hernia injection therapy is theoretically a method of injecting adhesives or sclerosing agents (such as glycerol lithate, sodium cod liver oil, compound quinine, medical gum, etc.) into the inguinal canal to cause aseptic inflammation of the hernia sac or the tissue around the hernia sac neck, fibrous hyperplasia, formation of adhesions and occlusion of the hernia sac. Injection therapy is very blind, it is a blind exploratory operation, and it is difficult to determine its depth, level and site. The anatomical level of the groin is fine and complex, so the location can only be roughly estimated when injecting, and it is difficult to determine whether the defective area can be plugged. In addition, the injection site formed a hard mass, into broken glass-like crystals, difficult to be absorbed by the body and the possibility of cancer; local injection of sclerosing agent not only has a very high recurrence rate, sclerosing agent can also cause intestinal adhesions, intestinal obstruction, intestinal perforation and even necrosis and other adverse reactions, serious cases may threaten life. In cases where injection therapy does not heal or recurrence requires surgery, the difficulty of surgery and the incidence of surgical complications increase significantly due to the formation of local scarring and tissue adhesions in the inguinal canal. Injectable treatment of inguinal hernia is a method that does not conform to the theory of inguinal hernia treatment, which has many complications, high recurrence rate, increases the difficulty of surgery, aggravates the surgical injury, causes difficulties in the later treatment and increases the burden of patients.
