AbstractObesity causes multiple conditions such as type 2 diabetes, cardiovascular disease, and so on, and an intervention is needed for controlling weight and improving metabolic syndrome. However, the effectiveness of lifestyle interventions and pharmacotherapy are restrictive for losing weight. Endoscopic sleeve gastroplasty (ESG) was developed as a new therapy, picking the best of both medication and surgery, less invasive and more effective. Recently, ESG is gradually spreading in Western countries, but there is Case report doesn't need conclusion/result for Japanese patients. We herein reported the first clinical case of ESG in Japan.Given the situation of the pandemic of COVID‐19, we could not invite a proctor from Western countries and receive the instruction of the device setting and maneuver face to face. Thus, we conducted the training for device setting, maneuver, and operation under a web‐based international remote collaboration. Eventually, we completed ESG without an adverse event. We could prove this web‐based proctor system was useful through the introduction of ESG in Japan. The international remote collaboration could become a new normal even in the endoscopy field post‐COVID‐19 era.

Natural orifice translumenal endoscopic surgery (NOTES) is a novel surgical concept that may provide a multitasking platform for minimally invasive surgery in the 21st century. With NOTES, natural hollow organs are used to gain access to body cavities via the mouth, anus, vagina, and urethra, thereby eliminating skin incisions. Access to the body cavity through the entry portal for the NOTES procedure and closure of the portal after surgery are important treatment considerations. In this review, access and closure techniques for NOTES-related procedures are discussed. Technical descriptions for access are also described. Closure techniques using experimental and commercially available devices are also reviewed. Based on the experimental and early clinical experiences to date, the future of NOTES appears quite promising. Nonetheless, ongoing fundamental research is necessary to determine the safety and benefit of these procedures. While technical challenges are currently present, the issues are being resolved with the development of optimal instrumentation and techniques. We believe that once standardized safe and reliable access and closure techniques are established, a major shift in minimally invasive surgery will likely be inevitable.
