To determine the effect of β-blocker continuation on outcomes in patients undergoing elective noncardiac surgery, Kwon and colleagues studied patients included in the Surgical Care and Outcomes Assessment Program, a Washington quality improvement benchmarking initiative. Patients underwent elective colorectal and bariatric surgical procedures at 38 hospitals between January 2008 and December 2009.
van der Wilden et al determine the rates and predictors of failure of nonoperative management of grade 4 and grade 5 blunt liver injuries and find that nonoperative management was offered safely in two-thirds of cases, with a 91% success rate. See Invited Critique by Kispert concerning nonoperative management of blunt liver injuries.
To measure the incidence and severity of orthopedic surgical resident fatigue and the associated relative risk of medical error, McCormick et al continuously recorded residents’ sleep and awake periods via actigraphy and used a daily questionnaire to analyze mental fatigue. See the related invited critique by Tracy.
Lee and coauthors analyzed national trends in the nonoperative management of pediatric splenic injury through retrospective analysis of 2 national databases. In their invited critique, Aidlen and Luks suggest that rates of nonoperative management can be improved.
To determine the risk factors for symptomatic anastomotic leakage after colorectal resection, Slieker and colleagues reviewed the records of 259 patients who underwent left-sided colorectal anastomoses in the Analysis of Predictive Parameters for Evident Anastomotic Leakage study.
In a matched-pair study, Romy et al determine if Roux-en-Y gastric bypass provides superior results to gastric banding in the treatment of morbidly obese patients.
Abi-Haidar et al compare outcomes between patients with acute cholecystitis undergoing percutaneous cholecystectomy and those undergoing cholecystectomy alone. The editorial by Orlando discusses the nuances of surgical decision making in this patient population.
Based on self-administered survey sent individually to women surgeons in training and practice, Turner and colleagues assessed experiences related to childbirth and pregnancy among women general surgeons. Participants were from the Association for Women Surgeons and the American College of Surgeons who graduated from medical school and practice general surgery or a general surgery subspecialty.
To examine the outcomes of and parental satisfaction with same-day discharge in children undergoing laparoscopic appendectomy, Alkhoury et al studied operative and postoperative details in 207 consecutive cases of acute or interval appendectomy.
Previous work showed that a subset of natural killer T cells in mice decreased the antitumor efficacy of live attenuated Listeria monocytogenes against murine hepatic colorectal cancer metastases. Olino and colleagues hypothesize that specific glycolipids that selectively stimulate natural killer T-cell subsets used alone or co-administered with Listeria monocytogenes would increase survival.
