How to teach evidence-based surgery.

The objectives of teaching evidence-based surgery (EBS) are to inform and convince that EBS is a method of interrogation, reasoning, appraisal, and application of information to guide physicians in their decisions to best treat their patients. Asking the right, answerable questions, translating them into effective searches for the best evidence, critically appraising evidence for its validity and importance, and then integrating EBS with their patients' values and preferences are daily chores for all surgeons. Teaching and learning EBS should be patient-centered, learner-centered, and active and interactive. The teacher should be a model for students to become an expert clinician who is able to match and take advantage of the clinical setting and circumstances to ask and to answer appropriate questions. The process is multistaged. Teaching EBS in small groups is ideal. However, it is time-consuming for the faculty and must be clearly and formally structured. As well, evidence-based medicine (EBM) courses must cater to local institutional needs, must receive broad support from the instructors and the providers of information (librarians and computer science faculty), use proven methodologies, and avoid scheduling conflicts. In agreement with others, we believe that the ideal moment to introduce the concepts of EBM into the curriculum of the medical student is early, during the first years of medical school. Afterward, it should be continued every year. When this is not the case, as in many countries, it becomes the province of the surgeon in teaching hospitals, whether they are at the university, are university-affiliated, or not, to fulfill this role.

Treatment of hydatid cyst of the liver: where is the evidence?

Treatment of hydatid cyst of the liver ranges from surgical intervention (conventional or laparoscopic approach) to percutaneous drainage and to medical therapy. The aim of this systematic review was to provide "evidence-based" answers to the following questions: Should chemotherapy be used alone or in association with surgery? What is the best surgical technique? When is the percutaneous aspiration injection and reaspiration technique (PAIR) indicated? An extensive electronic search of the relevant literature without limiting it to the English language was carried out using MEDLINE and the Cochrane Library. Key words used for the final search were "hydatid cyst," "liver," "treatment," "meta analysis," "randomized controlled trial," "prospective study," "retrospective study." All relevant studies reporting the assessment of one modality of treatment or a comparison of two or several therapeutic methods to treat hydatid cyst of the liver and published in a peer-reviewed journal were considered for analysis. This systematic review allowed us to conclude that chemotherapy is not the ideal treatment for uncomplicated hydatid cysts of the liver when used alone (level II evidence, grade B recommendation). The level of evidence was too low to help decide between radical or conservative treatment (level IV evidence, grade C recommendation). Omentoplasty associated with radical or conservative treatment is efficient in preventing deep abscesses (level II evidence, grade A recommendation). The laparoscopic approach is safe (level IV evidence, grade C recommendation). Drug treatment associated with surgery (level II evidence, grade C recommendation) requires further studies. Percutaneous drainage associated with albendazole therapy is safe and efficient in selected patients (level II evidence, grade B recommendation). The level of evidence is low concerning treatment of complicated cysts.

Dysphagia after Laparoscopic 360 Repair for Gastroesophageal Reflux Disease.

In comparison to medical treatment, antireflux surgery is recognized as an effective, efficient and longlasting therapy, as well as the only treatment that is able to modify the natural history of gastroesophageal reflux disease (GERD). The 360 fundoplication is the most widely used surgical procedure for GERD. Although performed in the era of H2-blockers and open surgery, comparison of the so-called Nissen repair to both symptomatic and continuous medical therapies concluded that surgery was superior to medical therapy in every outcome measure used.
