Several recent reports have shown a lymphedema rate of about 7% with sentinel lymph node biopsy (SLNB) only. We hypothesized that this higher than expected rate of lymphedema may be secondary to disruption of arm lymphatics during an SLNB procedure. ⋯ Disruption of the blue ARM node because of proximity to the hot SLN may explain the surprisingly high rate of lymphedema seen after SLNB. Identifying and preserving the ARM blue nodes may translate into a lower incidence of lymphedema with SLNB and axillary lymph node dissection.

The concept that premenopausal female patients are more resistant to shock than male patients has been shown in numerous preclinical models. The more relevant effect of gender on clinically important outcomes after trauma is less clear. Clinical studies have been conflicting, both supporting and refuting the protective effects of gender on outcomes, primarily because of limitations in sample size and patient stratification. In an attempt to resolve this ongoing dispute, we evaluated the effect of gender on various outcomes in the largest single institutional series of trauma patients reported in the literature after blunt injury. ⋯ Multivariable logistic regression analysis of a large trauma cohort definitively establishes that gender is not independently associated with mortality after blunt trauma in humans. In contrast, male gender was shown to be associated with increased morbidity. Unlike rodent studies, gender alone offers no survival advantage in humans after blunt trauma.

We reviewed our obesity surgery database for 2 experienced bariatric surgeons since their last patient death in October 2003 through July 2007. ⋯ Results for laparoscopic Roux-en-Y gastric bypass improve with experience and can be taught in an academic training program, with low morbidity and mortality. Routine postoperative upper gastrointestinal contrast studies are unnecessary and may lengthen hospital stay.

Comparative Study
Does race influence outcomes after primary liver transplantation? A 23-year experience with 2,700 patients.
Data about the influence of race on survival after liver transplantation (LT) are limited and conflicting. This study was undertaken to evaluate longterm outcomes for LT in African-American (AA) recipients compared with recipients of other races and to determine factors responsible for any observed differences. ⋯ This is the first study to demonstrate equivalent longterm results after LT for AA and other races. Modern immunosuppression with tacrolimus substantially lowered rejection rates and improved graft and patient survival after LT.

Patients with borderline resectable pancreatic adenocarcinoma (PA) include those with localized disease who have tumor or patient characteristics that preclude immediate surgery. There is no optimal treatment schema for this distinct stage of disease, so the role of surgery is undefined. ⋯ This is the first large report of borderline resectable PA and includes objective definitions for this stage of disease. Our neoadjuvant approach allowed for identification of the marked subset of patients that was most likely to benefit from surgery, as evidenced by the favorable median survival in this group.
