In a cross-sectional study, Glance et al examine the association between the American College of Surgeons Committee on Trauma quality indicators and outcomes.
In a retrospective study, Pendlimari et al determine how many cases are required to achieve technical proficiency for hand-assisted laparoscopic surgery.
In a retrospective database analysis, Masoomi and coauthors determine the frequency of splenic injury and evaluate predictive risk factors of splenic injury during colorectal surgery. An invited critique suggests that, despite potential rationalizations for their finding, the differences reported should not be so easily dismissed.
Saunders et al determine the effects of body mass index on outcomes after liver resection performed at Veterans Affairs medical centers. In an invited critique, Millis provides a commentary.
In a retrospective review of consecutive patients undergoing thyroidectomy, Landry and coauthors identify patients at risk for symptomatic hypocalcemia and make recommendations for safe, selective calcium supplementation. An invited critique suggests that their approach can be performed either in the hospital or in an outpatient laboratory and can be considered “sound clinical judgment.”
In a prospestive cohort study of patients undergoing elective left-sided colon or rectal resections at 40 hospitals, Kwon and coauthors compare the incidence of leaks after colorectal operations between hospitals that perform routine testing vs those that use selective testing.
In a retrospective study, Roman et al determine if anatomic changes induced by large hiatal hernia alter esophageal pressure topography measurements made during high-resolution manometry.
Angenete et al find that for a majority of the abdominal surgical procedures studied, the risk of small-bowel obstruction with open surgery is at least 4 times that with laparoscopy. In the related editorial, Funk and Ashley believe that laparoscopy offers an opportunity for improved quality of life and decreased morbidity.
Huh et al evaluate the prognostic value of macroscopic ulceration, tumor border configuration, and tumor-infiltrating lymphocytes at the invasive margin in patients with colorectal cancer. In the related editorial, Bland discusses outcomes risk among these patients.
Sørensen performed a systematic review and meta-analysis to clarify the evidence on smoking and postoperative healing complications across surgical specialties and to determine the impact of perioperative smoking cessation intervention. In the related commentary, Winter discusses the moral imperative of smoking cessation.
Lonze and colleagues investigated the delivery of hepatitis C virus–specific short hairpin RNAs to uninfected explanted grafts to protect against subsequent infection after transplantation.
