Objective: Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an important variation in minimally invasive surgery (MIS) nowaday. We would like to present the techniques and the results of the pure transanal and transvaginal laparoscopies (NOTES) in treatment of colorectal cancer. Material and method: Prospective study at Hue Central Hospital, Vietnam. Patients: From December 2013 to December 2015, 22 cololorectal cancers (17 rectum, 4 sigmoid tumors and 1 descending colon), adenocarcinoma, T≤ T3N1M0. Methods: The patients were placed in the lithotomy and Trendelenburg position, and the lone-star retractor was placed in anus (rectum cancer) or vagina (sigmoid cancer). Inflating of surgical cavity with CO2 and setting at 12 mmHg. Continuing dissection until go inside of the abdominal cavity (transanal technique), after that, the rectum was pushed into the abdominal cavity. The IMA, IMV were divided (TME included) in both techniques. After finishing dissection, specimens were pulled out through the anus or vagina to prepare anastomosis. The coloanal or colorectal anastomosis was performed by hand-sewn (6 cases) or by EEA staplers (16 cases). Results: 3 patients needed one more 5 mm umbilical port in RLQ, 1 patient needed two 5mm trocars (post radiation hemorrhagy, urethral perforation,…). 1 patient converted to open and 1 patient converted to HYBRID-NOTES procedure. The operation time was 258 ± 40 (190 - 300). All patients required minimal analgesia. Bowel movement returned on the first day in 16 patients (average: 2 days, maximum: 3 days). The hospital stay was 8 ± 2,6 (4 -14 days). Kirwan clasification (sphinter function) is very good (stage I: 16). Conclusions: Pure transanal and transvaginal laparoscopies in treatment of colorectal cancer are feasible and safe. It seems to be the first pure transvaginal laparoscopy (NOTES) for human in the world. However, a multicentric studies and long follow-up are necessary. Key words: Natural Orifice Transluminal Endoscopic Surgery (NOTES), colorectal cancer, Pure transanal

Natural orifice transluminal endoscopic surgery (NOTES) is a relatively new surgical access for minimally invasive surgery, which is being widely studied in human medicine. However, few studies focusing on its applicability in the small animal practice have been performed so far. The aim of the current study was to evaluate the feasibility of pure-NOTES transvaginal ovariohysterectomy in bitches. Five bitches were evaluated. The abdomen was accessed through an 11mm trocar inserted through a vaginal incision. Using a rigid endoscope with working channel, the ovarian pedicles were coagulated and sectioned using bipolar diathermy. The uterine horn was pulled into the trocar and exteriorized along with the cannula. The uterine body and vessels were coagulated or ligated. The uterine stump was replaced into the abdominal cavity and the pneumoperitoneum drained. Pure-NOTES OHE was successfully accomplished in four out of five bitches. In the first try, it was converted to a hybrid-NOTES technique due to instrument failure. Mean surgical time was 52.1 (SD±11.5 minutes) for the pure-NOTES technique. Pure-NOTES OHE is feasible in bitches, which may result in no major complications and excellent surgical recovery.

Objective. To assess outcome and safety of 571 hybrid natural orifice transluminal endoscopic surgery (NOTES) cholecystectomies. Methods. We retrospectively analyzed all consecutive NOTES cholecystectomies performed at our center between June 2009 and January 2018. All procedures were performed using a hybrid transvaginal technique, including an umbilical small-size trocar. End points, calculated at discharge, 30 and up to 90 days postoperatively, included intra- and postoperative morbidity assessed by the validated Clavien–Dindo classification and the Comprehensive Complication Index (CCI). Special focus was held on outcome and necessity of pre- and postoperative gynecological examinations. Results. We performed 571 hybrid NOTES cholecystectomies within 9 years. The vast majority were elective, 9.6% were emergency cholecystectomies. 6.7% of patients developed at least one complication until discharge, most of them minor (≤grade II). 30- and 90-day complication rates were 10.7% and 11%, respectively. Mean CCI at discharge and postoperative days 30 and 90 was 1.45 (±6.4), 2.3 (±7.7), and 2.4 (±7.8), respectively. Major complications (≥grade IIIa) occurred in 1.6% of patients, and 4 patients required emergency reoperation. No mortality was observed. In 9.8%, an additional abdominal trocar was placed. All patients underwent routine gynecological examination, whereof only 5 were rejected for transvaginal access preoperatively. In no case transvaginal access was discontinued intraoperatively due to gynecological disease. Conclusion. Hybrid NOTES transvaginal cholecystectomy represents a safe and feasible alternative to standard laparoscopic cholecystectomy. Preoperative gynecological examination is no longer routinely necessary, as intraoperative assessment is adequate.

The Times

Although laparoscopic colectomy shows superior short-term outcomes and similar oncologic outcomes in comparison to conventional open colectomy, incision-related complications have weakened its advantages. The natural orifice transluminal endoscopic surgery (NOTES) has been considered as the most perfect surgical approach. However, monumental technical hurdles have precluded widely adoption of this technique. As a transient mode, the natural orifice specimen extraction surgery (NOSES) emerges as the times require. Although it is accepted by surgeons for the treatment of colorectal cancer, there are still many disputes that need to be solved.

Natural orifice transluminal endoscopic surgery (NOTES) has generated healthy and vigorous debate about the introduction of an entirely novel method of surgical therapy. Although there are many reasons for scepticism, there is undoubted interest in this field from both the medical profession and general public. Those Associations currently involved in laparoscopic and endoscopic surgery wish to safeguard patients and the reputation of the profession by issuing clear guidance and support for those wishing to undertake NOTES. The purpose of this document is to review the current status of both NOTES and hybrid NOTES, while at the same time identifying obstacles in both clinical research and training. Furthermore, it aims to provide a consensus statement on behalf of the main UK specialty associations involved in this field of surgery. The primary aim of this consensus statement is to provide a framework within which to develop, safely and effectively, what must still be considered an experimental technique.

Natural Orifice Transluminal Endoscopic Surgery (NOTES) involves accessing the abdominal cavity via one of the bodies’ natural orifices, for example, mouth, anus, or vagina. This new surgical procedure is very appealing from patients’ perspectives because it eliminates completely abdominal wall aggression and promises to reduce postoperative pain, in addition to all other advantages brought by laparoscopic surgery. However, the constraints imposed by both the mode of access and the limited technology currently available make NOTES very challenging for the surgeons. Redesign of the instruments is imperative in order to make this emerging operative access safe and reproducible. In this paper, we survey on the state-of-the-art devices used in NOTES and introduce both the flexible instruments based on improvement of current endoscopic platforms and the revolutionary concept of robotic platforms based on the convergence of communication and micromechatronics technologies. The advantages and limitations of each category are addressed. Potential solutions are proposed to improve the existing designs and develop robust and stable robotic platforms for NOTES.

Chapter 18 discusses natural orifice translumenal endoscopic surgery (NOTES), which is currently investigated as an experimental alternative to diagnose and treat abdominal pathology combining endoscopic and laparoscopic techniques. Using a translumenal approach, the abdominal cavity is accessed with flexible endoscopes through an incision in the stomach, colon, or vagina. By obviating abdominal incisions, this approach may be less invasive than standard surgical techniques. This novel technique is currently performed at a few academic research institutions, but these less invasive operations potentially can be performed in an office-based setting in the future.

Natural orifice translumenal endoscopic surgery (NOTES) had its origins in numerous small animal studies primarily examining safety and feasibility. In human trials, safety and feasibility remain at the forefront; however, additional logistic, practical, and regulatory requirements must be addressed. The purpose of this paper is to evaluate and summarize published studies to date of NOTES in humans. The literature review was performed using PUBMED and MEDLINE databases. Articles published in human populations between 2007 and 2011 were evaluated. A review of this time period resulted in 48 studies describing procedures in 916 patients. Transcolonic and transvesicular procedures were excluded. The most common procedure was cholecystectomy (682, 75%). The most common approach was transvaginal (721, 79%). 424 procedures (46%) were pure NOTES and 491 (54%) were hybrid NOTES cases. 127 (14%) were performed in the United States of America and 789 (86%) were performed internationally. Since 2007, there has been major development in NOTES in human populations. A preponderance of published NOTES procedures were performed internationally. With further development, NOTES may make less invasive surgery available to a larger human population.
