We examined 200 normal elbows to assess the usefulness of ultrasonography in examining the ulnar nerve in the cubital tunnel. On longitudinal images in elbow extension, the nerve changed its course at the fibrous band region 11.5 (SD 2.8) mm distal to the medial epicondyle. On axial images, the diameter of the major axis of the nerve was 3.1 (0.5) mm and that of the minor axis was 1.9 (0.4) mm in men. The respective values were 2.7 (0.4) mm and 1.8 (0.4) mm in women. Dynamic studies showed that in 53 elbows (27%), the nerve moved on to the tip of the epicondyle with the elbow flexed and in 39 elbows (20%), the nerve dislocated anteriorly. The diameters of the hypermobile nerves were significantly larger than nerves that did not displace.

Visceral adiposity and sarcopenic visceral obesity, as well as low muscle mass and quality, were closely associated with mortality and recurrence after resection of pancreatic cancer.

Preoperative sarcopenic obesity was an independent risk factor for death and HCC recurrence after hepatectomy for HCC.

Although stage was the most important factor, low skeletal muscle mass and quality were closely related to mortality after resection of ICC in patients with stage I-III.
