Multicenter Study
Comparison of the outcomes of hemorrhoidectomy and PPH in the treatment of grades III and IV hemorrhoids.
To investigate the clinical effect and outcome of traditional hemorrhoidectomy and procedures for prolapse and hemorrhoid (PPH) for the treatment of grades III and IV hemorrhoids. We retrospectively reviewed 1003 grades III and IV hemorrhoid patients who presented to our hospital. A total of 585 patients underwent PPH, and 418 patients underwent hemorrhoidectomy. ⋯ It can reduce postoperative and surgery-related complications. However, this was a single-hospital retrospective study. Therefore, well-designed, multicenter, randomized controlled trials are needed to evaluate the value of PPH for grades III and IV hemorrhoids.

High-Sensitivity Troponin I after Cardiac Surgery and 30-Day Mortality.
Consensus recommendations regarding the threshold levels of cardiac troponin elevations for the definition of perioperative myocardial infarction and clinically important periprocedural myocardial injury in patients undergoing cardiac surgery range widely (from >10 times to ≥70 times the upper reference limit for the assay). Limited evidence is available to support these recommendations. ⋯ The levels of high-sensitivity troponin I after cardiac surgery that were associated with an increased risk of death within 30 days were substantially higher than levels currently recommended to define clinically important periprocedural myocardial injury. (Funded by the Canadian Institutes of Health Research and others; VISION Cardiac Surgery ClinicalTrials.gov number, NCT01842568.).

Multicenter Study Observational Study
Evaluation of International Contemporary Operative Outcomes and Management Trends Associated With Esophagectomy: A 4-Year Study of >6000 Patients Using ECCG Definitions and the Online Esodata Database.
This study aims to verify the utility of international online datasets to benchmark and monitor treatment and outcomes in major oncologic procedures. ⋯ The Esodata database provides a valuable resource for assessing contemporary international outcomes. This study highlights an increased application of minimally invasive approaches, a high percentage of complications, improvements in pneumonia and key quality metrics, but with anastomotic leak rates still >10%.

Randomized Controlled Trial Multicenter Study
Hyperoxia and Antioxidants for Myocardial Injury in Noncardiac Surgery: A 2 × 2 Factorial, Blinded, Randomized Clinical Trial.
Hyperoxia and oxidative stress may be associated with increased risk of myocardial injury. The authors hypothesized that a perioperative inspiratory oxygen fraction of 0.80 versus 0.30 would increase the degree of myocardial injury within the first 3 days of surgery, and that an antioxidant intervention would reduce degree of myocardial injury versus placebo. ⋯ Perioperative interventions with high inspiratory oxygen fraction and antioxidants did not change the degree of myocardial injury within the first 3 days of surgery. This implies safety with 80% oxygen and no cardiovascular benefits of vitamin C and N-acetylcysteine in major noncardiac surgery.

Association of postoperative complications with persistent post-surgical pain: a multicentre prospective cohort study.
Persistent post-surgical pain is an important and under-recognised problem that is difficult to treat. Postoperative complications have been identified as possible risk factors for persistent post-surgical pain. We conducted a secondary analysis of the Measurement of Exercise Tolerance before Surgery (METS) cohort study to characterise the association of major postoperative complications with post-surgical pain at 30 days and 1 yr after major surgery. ⋯ Patients who developed major complications were more likely to report pain at 30 days and possibly 1 yr after surgery. Research is necessary to validate these findings and delineate underlying mechanisms.
