Abstract:

Natural orifice specimen extraction surgery (NOSES) and enhanced recovery after surgery (ERAS) are the current hot topic in the field of abdominal minimally invasive surgery. The multidisciplinary and multimodal approach consists of the whole course management of preoperative preparation, anesthesia and analgesia, minimally invasive surgery and postoperative rehabilitation with the core principle of reducing surgical trauma and stress, accelerating recovery. Recently, our team has made efforts to explore the effect of optimal combination of minimal invasive surgery, precise anesthesia, whole-course pain management, as well as strict preoperative preparation and postoperative follow-up to minimize the physical and mental stress and trauma of surgical patients.
