A New Laparoscopic Surgical Procedure to Achieve Sufficient Mesorectal Excision in Upper Rectal Cancer
Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric vessels, we dissected the mesorectum along the layer of the planned total mesorectal excision. The rectal wall was carefully separated from the mesorectum at the appropriate anal side from the tumor. After the rectum was isolated and transected using an endoscopic linear stapler, the rectal stump drew immediately toward the anal side, enabling the mesorectum to be identified clearly. In this way, sufficient TSME can be performed easily and accurately. This technique has been successfully conducted on 19 patients. Conclusion. This laparoscopic technique is a feasible and reliable procedure for achieving sufficient TSME
Visualization of Bubble and Large Particle Movements in a Fluidized-Bed of Binary Mixture of Particles
Fluidized-bed combustion systems are composed of many kinds of particles with avariety of sizes,e.g.coal,sand,RDF,limestone etc.ln such a binary system of particles,the segregation,if occurs,many harm the combustion,mixing and heat transfer in the bed,depending on the particle movement. The particle movement or circulation in the fluidized-bed depends on many factors,such as the density ratio,size ratio,shape of particle,fluidization velocity. Owing to the difficulty of flow visualization,such particle movement has not been fully understood so far. This paper describes large-particle movement obtained by the flow visualization using neutron radiography. Tracer particles mixed into the fluidized particles indicated clearly bubbles and the cloud behavior around the bubble. Image processing,i.e. PIV and PTV,gives rather clear understanding on the interaction between the large particle,emulsion and/or cloud behavior in the bed
