Abstract
Anastomotic leakage is a worldwide problem in gastrointestinal surgery which seems to be related to the state of microcirculation. Laser speckle contrast imaging (LSCI) could give surgeons insight in the state of microcirculation to attune the site of anastomosis. This work studies the feasibility of LSCI as a tool for this purpose. An experimental setup was developed using a commercially available laparoscopic video system. Laser speckle contrast imaging is capable of detecting ischemic areas on the large intestine. Further research and development are required before adaptation of this technique in the operating room.
摘要
吻合口漏是胃肠外科领域一个全球性的问题，似乎与微循环状态有关。激光散斑对比成像（LSCI）可以让外科医生了解微循环状态，从而调整吻合部位。本研究探讨了将LSCI作为实现此目的工具的可行性。利用商用腹腔镜视频系统开发了一种实验装置。激光散斑对比成像能够检测大肠上的缺血区域。在手术室应用这项技术之前，还需要进一步的研究和开发。
