The discovery that the bacterium Helicobacter pylori (H. pylori) lives in the stomach has rendered out-of-date the concept of inhospitality of the gastric environment. H. pylori is able to survive in this organ through mechanisms of acid resistance and colonization factors. The prevalence of H. pylori infection varies depending on age, socioeconomic class, and country. ⋯ For patients having previously received a clarithromycin-containing regimen, this drug should be avoided as a second-line therapy. In this case, the tailored therapy (to test clarithromycin susceptibility before prescribing drugs) or the so-called quadruple therapy, and triple levofloxacin-based therapy should be proposed. Rifabutin- and furazolidone-based treatments should be reserved for further treatment.

Robot-assisted surgery emerged and evolved in order to increase the surgical precision and due to the need to overcome the drawbacks of conventional minimally invasive surgery. In thoracic surgery the first reported use of a robotic device was in a series of 12 patients with different lung pathologies with the assistance of the DaVinci Robotic Surgical System in 2002. The DaVinci system has been used for various procedures in the field of thoracic surgery since then. While its advantages for the resection of early stage thymoma have been well documented, its role in the treatment of lung cancer and other pathologies is still under investigation. ⋯ Although numerous studies have shown the feasibility and safety of robotic surgery for various procedures, they were not able to show superior postoperative outcomes in terms of morbidity and mortality in exchange for the higher costs of robotic surgery compared to conventional video-assisted thoracic surgery (VATS), except for early-stage thymoma resection. Therefore, randomized control trials comparing robotic particularly with VATS, but also with open procedures are required to further evaluate this crucial topic.
