To validate the authors' published surface landmarks for gaining percutaneous access to the internal jugular vein (IJV), and to determine whether these surface landmarks were altered after neck surgery. ⋯ Duplex imaging validated the accuracy of the surface landmarks for IJV cannulation and documented the adverse effects of neck rotation. IJV anatomy is not altered after CEA.

Comparative Study
Comparison of quality of life in patients undergoing abdominoperineal extirpation or anterior resection for rectal cancer.
To evaluate the quality of life (QoL) in patients undergoing anterior resection (AR) or abdominoperineal extirpation (APE) for rectal cancer in a sample of patients recruited from a field trial. ⋯ Patients undergoing APE do not have a poorer QoL than patients undergoing AR. Patients undergoing low AR have a lower QoL than those undergoing APE. Attention should be paid to QoL concerns expressed by patients undergoing low AR.

To study the influence of a novel intermittent sequential pneumatic compression device (Lympha-press) on the adverse cardiac and peripheral hemodynamic changes induced by positive-pressure pneumoperitoneum (PPPn) in laparoscopic surgery. ⋯ Significant and individually variable central and peripheral hemodynamic changes are encountered during laparoscopic surgery with PPPn and the head-up tilt position. These are reversed by intermittent sequential pneumatic compression using Lympha-press.

To evaluate the correlation between serum vascular endothelial growth factor (VEGF) level and the clinicopathologic features in patients with hepatocellular carcinoma (HCC). ⋯ These results show that a high preoperative serum VEGF level is a predictor of microscopic venous invasion in HCC, suggesting that the serum VEGF level may be useful as a biologic marker of tumor invasiveness and a prognostic factor in HCC.

To analyze the authors' experience with sentinel lymph node biopsy (SLNB) and the subsequent incidence and pattern of recurrence in patients with positive and negative nodes. ⋯ Patients with positive sentinel nodes have a significantly increased risk for recurrence. The early pattern of first recurrence for patients with negative and positive results is characterized by a preponderance of locoregional sites, similar to that reported in previous series of elective lymph node dissection. These data underscore the need for careful pathologic analysis of the SLN as well as a careful, directed locoregional physical examination in the follow-up of these patients.
