Abstract:
PURPOSE: This study was performed to design a safe air-pressure reduction system which can absorb rapidlyrising intraluminal pressure during intussusception, and comparison with other reduction systems to test itsclinical availability. MATERIALS AND METHODS: The air-pressure reduction system consisted of a pressure gauge,air insufflators, a pressure controller, buffers, and rapid exhaustion devices, and to determine itsabsorbability, it was connected with a bowel model. By using it in 20 infants with intussusception, we comparedthe absorbability of our air-pressure reduction system with preexisting systems. RESULTS: While extraluminalpressure was applied to the bowel model in which baseline intraluminal pressure was set to 120mmHg, this rose to176mmHg (56mmHg high to standard, 100%) in the direct infusion system, but to only 130 mmHg (10mmHg high tostandard, 17.9%) in a system connected to a large buffer of 10,500 mL capacity. Immediately after the applicationof extraluminal pressure for less than 1 sec, this air-pressure reduction system showed better absorbability thanthe hydrostatic reduction system. Applying this system to 20 infants with intussusception, this was successfullyreduced in 19 cases(95%), without complications. CONCLUSION: In this experiment, it was proved that the systemabsorbed rapid intraluminal pressure elevation. Its use would help prevent bowel perforation during air reductionoccurring during intussusception.
