In a cohort study, Birkmeyer et al evaluate the effectiveness and safety of 3 predominant venous thromboembolism prophylaxis strategies among patients undergoing bariatric surgery.
Kazaure et al describe procedure-specific types, rates, and risk factors for postdischarge complications occurring within 30 days after 21 inpatient general surgery procedures.
Among 1738 patients who underwent esophagectomy at 164 American College of Surgeons National Surgical Quality Improvement Program hospitals, Merkow and colleagues measured risk-adjusted 30-day outcomes and hospital-level variation in performance based on operative approach (transhiatal, Ivor Lewis, 3-field, and any approach with an intestinal conduit). See invited critique by Yang.
Momin and coauthors examine whether being uninsured is associated with higher in-hospital postoperative mortality when undergoing surgery in the United States for a brain tumor. See the invited critique by Hervey-Jumper and Maher.
Feuerbacher and colleagues hypothesized that realistic operating room distractions and interruptions (ORDIs) induce errors in a simulated surgical procedure performed by novice surgeons. For the study, 18 second-year, third-year, and research-year surgical residents completed a within-subjects experiment on a laparoscopic virtual reality simulator.
In a retrospective review, Falor and coauthors hypothesize that patients with mild gallstone pancreatitis may undergo an early laparoscopic cholecystectomy within 48 hours of hospital admission without awaiting normalization of pancreatic and liver enzyme levels. An invited critique suggest that surgeons should feel more comfortable proceeding with an early laparoscopic cholecystectomy.
In a retrospective review, Cisco et al compare intraoperative parathyroid hormone profiles in African American patients with non–African American patients. In the related invited critique, Ryan discusses the need for randomized clinical trials on intraoperative parathyroid hormone kinetics.
Brenner and colleagues retrospectively reviewed 1547 consecutive patients with severe traumatic brain injury (TBI) who survived past 12 hours after hospital admission to investigate the relationship between oxygenation and short-term outcomes in patients with TBI.
Kapoor et al examine the long-term outcome of patients with early breast cancer with hematoxylin-eosin–negative sentinel lymph nodes who did not undergo completion axillary lymph node dissection.
Kevin P. Charpentier, MD, reviews irreversible electroporation (IRE) as a novel, nonthermal form of tissue ablation using high-voltage electrical current to induce pores in the lipid bilayer of cells, resulting in cell death. Steven D. Colquhoun, MD, provides a related critique.
