To identify the parameters related to the effective selection of patients who could receive prognostic benefit from lateral pelvic node dissection. ⋯ Advanced lower rectal cancer patients having LNI in the lateral pelvic area are likely to receive prognostic benefit from lymphadenectomy. The most efficient means of determining the effectiveness of lateral dissection preoperatively is to estimate the nodal diameter in the "vulnerable" lateral regions by diagnostic imaging.

The purpose of this study is to measure abdominal wall myopathic histologic and mechanical changes during incisional herniation and its effect on incisional hernia repairs. ⋯ The internal oblique muscles of the abdominal wall express a pattern of changes consistent with those seen in chronically unloaded skeletal muscles. The internal oblique muscles become fibrotic during herniation, reducing abdominal wall compliance and increasing the transfer of load forces to the midline wound at the time of hernia repair.

To review present knowledge of the influence of hepatic steatosis in liver surgery as derived from experimental and clinical studies. ⋯ Hepatic steatosis is a major factor determining patient outcome after surgery. Further research is needed to clarify the clinical relevance of all forms and severity grades of steatosis for patient outcome. Standardized grading and diagnostic methods need to be used in future clinical trials to be able to compare outcomes of different studies.

The objective of this study was to determine the relationship of race and socioeconomic factors and the method used for appendectomies in children (open vs. laparoscopic). ⋯ There are significant racial and insurance-related differences in use of laparoscopic appendectomy in children that are most evident at nonchildren's hospitals. These findings provide evidence that factors at hospitals dedicated to children may lead to better access to new technologies.

To assess a machine perfusion system in rescuing liver grafts from non-heart-beating donors (NHBD). ⋯ We demonstrate a beneficial effect of HOPE by preventing reperfusion injury in a clinically relevant NHBD model.
