Anderson et al report on their risk-adjusted tool used to measure surgical outcomes in resource-limited hospitals. The invited commentary by Farmer evaluates this potential tool for global comparative effectiveness.
Harari and coauthors examine whether increasing body mass index is associated with more aggressive disease and adverse surgical outcomes in patients with papillary thyroid cancer.
Inaba and coauthors conducted a retrospective study on patients with chest trauma, divided into quartiles by body mass index, to compare the distance to be traversed during needle decompression between the second intercostal space and midclavicular line with the fifth intercostal space in the anterior axillary line. In a related commentary, Schreiber discusses the need for such research.
Krampitz and coauthors performed prospective database searches to determine whether lymph node metastases decrease survival in patients with pancreatic neuroendocrine tumors. See the invited critique by Stabile.
Yaghoubian and colleagues conducted an 11-year retrospective analysis of 348 categorical general surgery residents at 6 West Coast programs to determine the rates and predictors of remediation and attrition among the residents. In an invited critique, Karen Deveney, MD, comments on the findings.
To determine the effect of preoperative MR imaging on reoperation rates in women with operable breast cancer, Weber et al performed selective imaging based on breast density and histologic findings. They measured rates of reoperation and pathologically avoidable mastectomy at initial operation. See also the invited critique by Lum.
Danczyk and coworkers used a retrospective cohort study to compare outcomes of primary vs secondary open operations for AIOD. See invited critique by Lee.
In a retrospective review, Nelson et al compare the outcomes of a large cohort undergoing biliopancreatic diversion/duodenal switch vs gastric bypass. In the Invited Critique, Beekley discusses duodenal switch vs gastric bypass.
To document whether discrepancies exist in complications and outcomes at level II teaching trauma centers vs nonteaching trauma centers, Bukur and colleagues performed a retrospective review of the 2007-2008 National Trauma Data Bank. The influence of house staff presence on failure to rescue was determined. See the related invited critique by Martin.
Cho and coauthors compare the outcomes of umbilical hernia repair in patients with and without signs of portal hypertension and assess the effect of emergency surgery on complication rates.
In a retrospective review of a prospectively maintained database, Kidner and coauthors hypothesize that preoperative imaging underestimates the number of pulmonary metastatic melanomas. See the invited critique by Bold.
Menen and coauthors examine the use of fluorescent laparoscopy in the detection of colon cancer metastases. See invited critique by Duh.
To guide the management of dominant thyroid nodules of the isthmus, Goldfarb et al studied 942 patients who had undergone surgeon-performed preoperative ultrasound and fine-needle aspiration, followed by thyroidectomy. They correlated preoperative findings and final pathologic results with malignancy vs benign thyroid disease in 28 patients having dominant thyroid nodules of the isthmus.
