In recent years, natural orifice specimen extraction surgery (NOSES) has been widely used in surgery of colorectal cancer. The rapid development of NOSES is mainly attributed to its own great advantages and values, including the reduction of surgical trauma, the acceleration of postoperative recovery and the reduction of adverse psychological reactions for patients. These advantages of NOSES are also important embodiment and perfect interpretation of the organ functional protection. Organ functional preservation is a hot topic in surgery today, and it is also an inevitable requirement for minimally invasive surgery. Essentially, NOSES and organ functional preservation are proposed in the same background, and the goals are highly compatible. NOSES is an important practitioner of organ functional preservation, and organ functional preservation is also the vane of the development of the theoretical system of NOSES. These two items complement each other and together constitute the important element in the development of modern minimally invasive surgery. In order to comprehensively discuss the relationship between NOSES and organ functional protection, we elaborate the important role and value of functional protection in NOSES from five key procedures of colorectal surgery, namely surgical approach, extent of resection, lymph node dissection, digestive tract reconstruction and specimen extraction.

Thanks to endoscopic assistance and the pressure effect of pelvic pneumoperitoneum, transanal total mesorectal excision (taTME) can better expose the surgical field of distal mesorectal space, and may have a prospect for the preservation of pelvic nerves and organ function. The transanal minimally invasive surgery (TAMIS) platform may decrease the injury of internal anal sphincter and protect anal function. Current data show that taTME procedure has similar results on postoperative anal function, urinary function and sexual function compared to transabdominal TME procedure. The early impaired anal function after taTME may be related to the transanal approach itself, implement of single port and the learning curve, but the anal function can improve with time. Regarding the protection of urinary and sexual function, the beginners should be familiar with the course of pelvic nerves, the anatomical landmarks and the technical points during the dissection upward, and try to avoid the injury of the pelvic plex trunk and pelvic splanchnic nerves. TaTME is different from natural orifice transluminal endoscopic surgery (NOTES), while the latter focuses on the minimally invasive principle, the former focuses on the oncological safety and nerve protection. We should combine the advantages of transanal and transabdominal approaches to achieve the final goal of surgical quality improvement and organ function preservation.

The surgical treatment of low rectal diseases has gradually changed from open radical operation to endoscopic minimally invasive operation. Transanal total mesorectal excision (taTME) combines endoscopic technique with transanal approach, and solves the problem of surgery exposure in lower rectal cancer. It has become an option for colorectal surgeons in lower rectal cancer. We named this operation as transanal endoscopic surgery, for the appropriateness when it is applied for other colorectal diseases. Transanal endoscopic surgery belongs to the category of natural orifice transluminal endoscopic surgery, which achieves the same pathological outcomes with less invasiveness and better organ functions compared with traditional surgery. It represents the tendency of low rectal surgery.

In recent years, our country has gained unprecedented achievements in minimally invasive surgery. Natural orifice specimen extraction surgery (NOSES), natural orifice transluminal endoscopic surgery (NOTES) and transanal total mesorectal excision (TaTME) are the three most representative techniques for minimally invasive surgery. They are hot in Chinese surgical field due to their superior minimally invasive advantages. It is true that these three technologies are still in their early stages of development. Each of them also faces many problems and challenges that need to be resolved and overcome. Therefore, it is necessary for us to understand these technologies thoroughly on the premise of accurate definitions, clear concepts, and standardized operating procedures. We should not blindly follow, nor should we confuse concepts and surgical names. This is an important prerequisite for the orderly development of minimally invasive surgery. NOSES emphasizes the removal of specimens through natural orifice, while NOTES mainly emphasizes the use of natural orifice as a surgical approach into the body cavity. TaTME emphasizes the trans-anal approach. NOSES and NOTES are two wide surgical concepts that apply to a variety of tissues and organs, while TaTME is a narrow surgical concept that is confined to the rectum. The main purpose of the three is to demonstrate a good minimally invasive effect on the basis of ensuring effective treatment of the disease. From the current technical conditions, no surgical technique is perfect. Only by selecting the best surgical method according to the patient's condition, can the advantages of minimally invasive technology be maximized, and patients can benefit the most.

Natural orifice transluminal endoscopic surgery (NOTES) is the latest surgical technique for inserting an endoscope through the mouth, anus, vagina etc., and for performing surgery with mucosal incision only, i.e., without skin incision. Recently, a number of researchers have applied NOTES to thyroid surgery in several trials, with the aim of removing the thyroid gland through oral cavity. The transoral endoscopic thyroid surgery became widely known after Anuwong et al. reported successful results for their first 60 patients and it has become increasingly recognized as a feasible novel surgical procedure. The purpose of this article is to review and summarize the existing literature, and describe in detail the preoperative considerations, rationale for patient selection, surgical method and postoperative management for transoral thyroid surgery.

Gastric outlet obstruction, afferent or efferent limb obstruction, and biliary obstruction among patients with altered anatomy often require surgical intervention which is associated with significant morbidity and mortality. Endoscopic dilation for benign etiologies requires multiple sessions, whereas self-expandable metal stents used for malignant etiologies often fail due to tumor in-growth. Lumen apposing metal stents, placed endoscopically with the intent of creating a de-novo gastrointestinal anastomosis bypassing the site of obstruction, can potentially achieve similar efficacy, with a much lower complication rate. In our study cohort (n=79), the composite technical success rate and clinical success rate was 91.1% (72/79) and 97.2% (70/72), respectively. Five different techniques were used: 43% (34/79) underwent the balloon-assisted method, 27.9% (22/79) underwent endoscopic ultrasound-guided balloon occluded gastro-jejunostomy bypass, 20.3% (16/79) underwent the direct technique, 6.3% (5/79) underwent the hybrid rendezvous technique, and 2.5% (2/79) underwent natural orifice transluminal endoscopic surgery (NOTES)-assisted procedure. All techniques required an echoendoscope except NOTES. In all, 53.2% (42/79) had non-cautery enhanced Axios stent, 44.3% (35/79) had hot Axios stent, and 2.5% (2/79) had Niti-S spaxus stent. Symptom-recurrence was seen in 2.8%, and 6.3% had a complication (bleeding, abdominal pain or peritonitis). All procedures were performed by experts at centers of excellence with adequate surgical back up.

Recently, an increasing interest in less invasive surgery has led to the advent of laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES). LESS and NOTES could be technically challenging, but available literature has demonstrated the feasibility and safety of LESS for benign gynecologic diseases. However, the evidence is not strong enough to recommend the use of LESS over that of conventional multiport laparoscopic surgery (MLS). As per the results of the most recently published meta-analysis, the majority of surgical outcomes are equivalent between LESS and MLS, except for the longer operative time in LESS for both adnexal surgery and hysterectomy. Although an increasing number of studies have reported on robotic LESS, NOTES, and LESS for gynecologic malignancy, definite conclusions have not been drawn owing to the lack of sufficient information.
