Multicenter Study
Hepatic resection for noncolorectal nonendocrine liver metastases: analysis of 1,452 patients and development of a prognostic model.
To determine the utility of hepatic resection (HR) in the treatment of patients with noncolorectal nonendocrine liver metastases (NCNELM). ⋯ HR for NCNELM is safe and effective, with outcomes mainly dependent on primary tumor site and histology. For individual patients, a statistical model based on key prognostic factors could validate the indication for hepatic resection by predicting long-term survivals.

To compare outcomes of appendectomy in an Acute Care Surgery (ACS) model to that of a traditional home-call attending surgeon model. ⋯ In patients with acute appendicitis, the presence of an in-house acute care surgeon significantly decreased the time to operation, rupture rate, complication rate, and hospital length of stay. The ACS model appears to improve outcomes of acute appendicitis compared with a TRAD home-call model. This study supports the efficacy and efficiency of the ACS model in the management of surgical emergencies.

This study examines donation after cardiac death (DCD) practices and outcomes in liver transplantation. ⋯ The annual number of DCD livers used for transplant has increased rapidly. However, DCD livers are associated with a significantly increased risk of graft failure unrelated to modifiable donor or recipient factors. Appropriate recipients for DCD livers have not been fully characterized and recipient informed consent should be obtained before use of these organs.

Comparative Study
Duodenal switch provides superior weight loss in the super-obese (BMI > or =50 kg/m2) compared with gastric bypass.
Although weight loss following Roux-en-Y gastric bypass is acceptable in patients with preoperative body mass index (BMI) between 35 and 50 kg/m, results from several series demonstrate that failure rates approach 40% when BMI is > or =50 kg/m. Here we report the first large single institution series directly comparing weight-loss outcomes in super-obese patients following biliopancreatic diversion with duodenal switch (DS) and Roux-en-Y Gastric Bypass (RYGB). ⋯ Direct comparison of DS to RYGB demonstrates superior weight loss outcomes for DS.

To determine whether analyzing more lymph nodes in colon cancer specimens improves survival. ⋯ Adequate lymphadenectomy, as measured by analysis of at least 15 lymph nodes, correlates with improved survival, independent of stage, patient demographics, and tumor characteristics. Currently, most procedures do not meet this guideline. Future trials of adjuvant therapy should include extent of lymphadenectomy as a stratification factor.
