According to the specific method, poloxamer, chitosan, polycarbophil, polyvinylpyrrolidone, iohexol and methylene blue are utilized to construct the novel intestinal canal filling temperature-sensitive gel injection. The injection can be injected into the anastomotic intestinal segment of the small intestine by using a conventional nasobiliary drainage tube which is clinically used at present, and the injection becomes viscous immediately under the action of the pH value of the small intestine after injection, so that the injection is inhibited from spreading all around. Meanwhile, the injection is quickly converted into high-strength hydrogel under the action of body temperature, and the hydrogel is adhered to small intestine mucosa to inhibit gel sliding. Therefore, the injection can form a section of gel on a target small intestine section, local immobilization filling and supporting of the target small intestine section are achieved, development can be achieved, the operation difficulty of intestinal tube puncture and stent placement in gastrointestinal anastomosis guided by an ultrasonic endoscope can be greatly reduced, the operation efficiency and the success rate are improved, and the operation cost is reduced. The dosage is less than that of normal saline which is conventionally used clinically, and the effect is better. Moreover, the gel temperature can be reduced by injecting low-temperature normal saline after the operation, so that the gel is thoroughly dissolved into a solution and discharged out of the body, and the phenomenon that the gel remains in the intestinal canal after the operation to cause obstruction is avoided. Therefore, the novel intestinal canal filling temperature-sensitive gel injection has very important clinical practical application value for gastrointestinal anastomosis guided by an ultrasonic endoscope.
