The Relationship between Temporal Changes in Proximal Neck Angulation and Stent-Graft Migration after Endovascular Abdominal Aortic Aneurysm Repair.

Background: In recent years, endovascular abdominal aortic aneurysm repair (EVAR) for treating abdominal aortic aneurysms (AAA) has become quite prevalent in Japan. Though little information is available about temporal changes in proximal neck angulation due to the difficulties encountered in measuring the angle. Therefore, we examined temporal changes in proximal neck angulation and its relationship to stent-graft migration after EVAR.

Transumbilical Hidden-Scar High Anterior Resection for Sigmoid Colon Cancer Using GelPOINT Through an Umbilical Zigzag Skin Incision.

Hidden-scar surgery is a new method by which surgeons perform abdominal operations through one incision made in the folds of the patient's umbilicus. However, with a straight incision in the umbilicus, the maximal opening of the fascia is 2 cm. The 2-cm fascial opening is not enough to allow for the triangulation of instruments, the removal of specimens, and the performance of anastomosis, particularly during gastrectomy and colectomy.

Haplotype analysis with 14 Y-STR loci using 2 multiplex amplification and typing systems in 2 regional populations in Japan.

In this study 14 Y-STR loci (DYS393, DYS19, DYS391, DYS437, DYS435, DYS439, DYS389II, DYS438, DYS436, DYS390, Y-GATA-H4, DYS385, Y-GATA-A7.1 and DYS392) were analysed in 207 Japanese males from Honshu (main island of Japan, Nagoya City) and 87 Japanese males from Okinawa (southernmost islands of Japan) using two multiplex PCR typing systems, a novel 10-plex amplification system and a new commercially available 6-plex typing kit which had two loci in common. The allele frequency distributions were similar at almost all of the 14 loci.
