Killian-Jamieson diverticulum mimicking a suspicious thyroid nodule: sonographic diagnosis.

Killian-Jamieson diverticulum is a rare form of pharyngoesophageal diverticula emerging in the anterolateral wall of the cervical esophagus. We present a case of Killian-Jamieson diverticulum that mimicked a thyroid nodule on sonography (US), and for which a US-guided fine-needle aspiration (FNA) was performed. The possibility of Killian-Jamieson diverticulum should be considered when a thyroid nodule is seen adjacent to the esophagus even without US change during/after swallowing.

Fixation methods for implantable port chamber: comparative study using glue, self-stabilizing leg and suture fixations in rabbits.

Objective: To evaluate the fixation strength and tissue reaction of the glue fixation and self-stabilizing leg fixation methods and to compare the results with those of the conventional tagging suture fixation method.

Materials And Methods: Twelve healthy rabbits were selected and three different methods of implanting the port chamber were employed on the back of each rabbit. A total of thirty six port chambers were implanted with these three different methods, viz.
