WJS Presents: We Asked The Experts

World Journal of Surgery announces a new regular feature: ‘We Asked The Experts’. 

This article series will be composed of succinct reviews of specific interesting topics or questions in surgery/medicine. WJS will highlight common clinical dilemmas, innovations in the delivery of clinical care, controversial issues, or cutting-edge developments in education, quality, safety, policy, global surgery, or other nonclinical areas relevant to practicing surgeons.

We Asked The Experts articles require a presubmission inquiry and approval. Contact the Editorial Office with your proposed topic:  worldjsurg@ohsu.edu


We Asked the Experts: How Can One Troubleshoot Loss of Intraoperative Nerve Monitoring During Head and Neck Surgery?

Here, we discuss practical tips and potential pitfalls that may aid surgeons in using the monopolar nerve stimulator for laryngeal neuromonitoring with a device that transforms laryngeal muscle activity into audible and visual electromyographic (EMG) signals. Read More


We Asked the Experts: “To Stent or Not to Stent… What is the Best Management of an Esophageal Leak or Benign Perforation?”

Since a review on this topic was published in 2014, the number of publications pertinent to this topic has more than doubled and the cumulative number of patients has increased from 340 to 1752 patients. Nevertheless, the results remain the same; metal stents perform better than plastic stents with a reduced risk of migration, perforation, and repositioning. The absolute percentage of technical and clinical success rates has also increased either reflecting improvements in stent design or greater experience in the insertion/removal of stents. But, has the review provided an answer to the surgeon’s question when faced with the dreaded anastomotic leak, or a Boerhaave’s perforation in the early hours of the morning? Read the full article for tips.


We Asked the Experts: Covid-19 Outbreak: Is There Still a Place for Scheduled Surgery? “Reflection from Pathophysiological Data”

Covid-19 pandemic severely hits the world, and many countries need to adapt their health systems to handle a large influx of patients with pneumonia due to this new virus. This unique crisis is putting a strain on our hospitals, which have to respond to the influx of patients with Covid-19. At the same time, physicians must provide care for patients suffering from other, and sometimes urgent, conditions. In this context, the management of patients requiring major oncological or cardiac surgery within adapted (often short) timeframes is a difficult preoccupation, especially since that some pathophysiological data on this virus leads us to believe that immunosuppressive changes due to surgery may increase susceptibility to the virus.
