- the polyglycolic acid felt is impregnated with a fibrillinogen solution, covered with a polyglycolic acid felt impregnated with a fibrillinogen solution, and the polyglycolic acid felt is placed on the polyglycolic acid felt covered with a circular defect hole. Fibrin glue was applied to cover the intestine around it.
- This method was performed using a rabbit with three holes at the duodenum, small intestine, and colon using a forceps of approximately 5 mm in diameter, which is about half the diameter of the intestine, on the serosal side of the intestine.
- the reason for selecting these three power sites is that the faecal character is at each site, and although the digestive tract volume is liquid in the duodenum, it is solid in the colon and the small intestine is semisolid in the middle. Intestinal bacteria are most common in the duodenum and low in the colon.
- the examination was conducted using 5 parts at different sites under conditions, but closure of the defect was complete at all sites, and all rabbits survived oral anesthesia after awakening.

- the intestine was removed by two birds and the lumen was examined, but the healing process progressed from the surroundings, and the defect hole had become about half the size.
- the belly was reopened for one month, but adhesions were mild and fibrin glue and absorbent felt were small nodules and attached to the serosal side. Two more birds removed the intestine and searched the lumen, but the closure was completely blocked. Nose on serosal side was further reduced and was in the absorption section in the laparotomy findings after 2 months.
- This method was performed using a rabbit with three holes at the duodenum, small intestine, and colon using a forceps of approximately 5 mm in diameter, which is about half the diameter of the intestine, on the serosal side of the intestine.
- the intestinal tract including the created defective part was extracted, one end was closed, the other end was connected to a pressure gauge, and the lumen pressure was raised by feeding air from the middle of the circuit, and the pressure at which the intestinal tract broke down in water was measured. .
- As a control an intestinal tract not treated with any treatment was compared with an intestinal tract which was closed in the same way as a defect.
- FIG. 1 is a schematic view showing a method of using a defect occlusion kit according to the present invention.
