We examined the theoretic possibility that therapeutic ultrasound can disrupt a stapled gastrointestinal anastomosis.
A case is reported in which leakage of a stapled ileocolic anastomosis occurred following therapeutic ultrasound. Calculations are performed on the power of the ultrasound beam and its adsorption and dispersion in the tissue between the probe and anastomosis to establish its intensity at the anastomosis.
Ultrasound intensity at the anastomosis in this patient was calculated at 10 to 46 mW/cm2.
Although the calculated ultrasound intensities at the anastomosis do not appear to be very high, other factors such as "pressure doubling" and "stress concentration" at the stapled surface suggest that therapeutic ultrasound may cause staple disruption.
我们研究了治疗性超声能够破坏吻合器吻合的胃肠道吻合口这一理论可能性。
报告了1例治疗性超声后发生吻合器回结肠吻合口渗漏的病例。对超声束的功率及其在探头与吻合口之间组织中的吸收和分散进行计算，以确定其在吻合口处的强度。
该患者吻合口处的超声强度经计算为10至46 mW/cm²。
虽然计算得出的吻合口处超声强度似乎不是很高，但诸如吻合钉表面的“压力加倍”和“应力集中”等其他因素表明，治疗性超声可能会导致吻合钉断裂。
