ABSTRACT
Surgical treatment of low rectal cancer is a difficult point in colorectal surgery, which has the problem of mutual restriction between radical resection and functional protection. With the development of laparoscopic total mesenterectomy, minimally invasive operation through anal endoscopy and the gradual improvement of the concept of natural orifice transluminal endoscopic surgery, the transanal total mesorectal excision (taTME) is formed in line with the principle of radical resection of rectal cancer. On the premise of ensuring radical resection, taTME can maximize organ preservation and function protection, and improve the quality of life of patients. 4K laparoscopic system can provide a clear surgical field and improve the surgical precision, which is helpful for the accurate anatomy of low rectal cancer. The authors share the clinical experience of 4K laparoscopy assisted taTME in order to provide references for surgical colleagues.
ABSTRACT
With the development of instruments and the innovation of techniques, gastrointestinal endoscopy is expanding the scope and scale in its application. As an important component of endoscopic therapeutic techniques, the development of endoscopic resection techniques is undoubtedly remarkable. The representative techniques including endoscopic submucosal dissection, submucosal tunneling endoscopic resection and natural orifice transluminal endoscopic surgery have made endoscopic resectable scope gradually extend from the initial intramucosal to the submucosal, and even extraserosal lesions. This article reviews the state of the art and advances of main endoscopic resection techniques.

ABSTRACT
Background: Laparoscopic cholecystectomy (LC) has evolved to be as gold standard treatment for gall bladder disease and is the most common laparoscopic procedure performed worldwide. In recent times, the innovative techniques of Natural orifice Transluminal Endoscopic Surgery (NOTES) and Single Incision Laparoscopic Surgery (SILS) have been applied as a step forward towards scar less surgery with added benefits of less pain and less analgesic requirement, shorter hospital stay, quick return to work.Methods: A retrospective study of 50 patients admitted with gall bladder disease through outdoor for laparoscopic cholecystectomy from November 2018 to January 2019 in Maharishi Markandeshwar Institute of Medical Sciences and Research Mullana (AMBALA) were randomized into two groups of 25 each for Single Incision Laparoscopic Cholecystectomy (SILC) and standard laparoscopic cholecystectomy (LC) comparing the operative time, outcome and complications.Results: 50 patients admitted to MMIMSR Mullana from November 2018 to January 2019 with gall bladder disease were divided into two groups of 25 each who underwent three port SILC and four port laparoscopic cholecystectomy (4PLC). The average intra-operative time in SILC (80.56 mins) was significantly more than standard laparoscopic cholecystectomy. The average length of stay in the hospital for SILC was 1.8 days (1-3 days), was significantly less than in standard four port laparoscopic cholecystectomy. Incidence of Intraoperative complications were more in SILC than standard LC.Conclusions: SILC as the newer novel technique had better outcomes in terms of cosmesis, early discharge, shorter stay at hospital.
ABSTRACT
Background: Natural orifice transluminal endoscopic surgery (NOTES) is a minimal invasive treatment. However, tissue dissection under endoscopy is still challenging due to the flexibility of endoscopy body and there is still no effective method for establishing a tunnel towards the targeted area. We previously showed that a new kind of thermogel could be submucosallly injected and served as a cushion for endoscopic dissection. Thus, in this study we investigated the feasibility and safety of tunnel creation using poly (lactic acid-co-glycolic acid)-poly (ethylene glycol)-poly (lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) thermogel for NOTES in a porcine model. Methods: We prepared an injectable thermogel composed of PLGA-PEG-PLGA triblock copolymers which exhibited a low-viscous sol at room temperature and spontaneously transformed into a no-flowing gel at body temperature. This thermogel was used in NOTES in pigs. The success rate and adverse events were observed. Results: The PLGA-PEG-PLGA thermogels were successfully injected to the targeted areas under the guide of endoscopic ultrasonography and the tunnels were created by sucking the gel during NOTES as the endoscopy went forwards in all the three animals. The necropsy of the pigs showed no evidence of iatrogenic injury. No serious bleeding and perforation was observed. The results demonstrated that thermogel injection and tunnel creation by suction during NOTES were feasible, which simplified the procedure of tissue dissection and developed a new method of identifying the targeted area for surgical interventions without causing severe tissue damage. Conclusion: The application of thermogel for tunnel creation in NOTES could optimize current procedures and may have a promising prospect in clinical application
ABSTRACT
RESUMEN El objetivo del trabajo es profundizar en los diferentes aspectos cognoscitivos sobre las nuevas evidencias concernientes al tratamiento de la apendicitis aguda y comparar los resultados obtenidos con las diferentes técnicas quirúrgicas empleadas actualmente y el tratamiento conservador. Se realizó una revisión bibliográfica y se seleccionaron artículos en las fuentes electrónicas: Web of Science, Scielo, Elsevier, PubMed, Medline y Google, publicadas en la presente centuria en idiomas español e inglés. La apendicetomía mediante laparotomía ha sido siempre la regla de oro para el tratamiento de la apendicitis aguda. En 1982, se introdujo el acceso laparoscópico que ha demostrado ser tan seguro y eficiente como el convencional. En 2004, la cirugía endoscópica a través de orificios naturales; en 2007 por un solo puerto y en 2015 mediante endoscopia retrógrada. La evolución del cuadro clínico es variable por lo que se han propuesto estrategias como la cirugía ambulatoria, el tratamiento conservador seguido o no de cirugía de intervalo, a fin de evitar intervenciones innecesarias con morbilidad y mortalidad similares a las realizadas con urgencia. La apendicetomía mediante laparotomía o laparoscopia aun es la regla de oro del tratamiento de la apendicitis aguda, aunque se impone el acceso laparoscópico, han surgido nuevas técnicas invasivas y la cirugía ambulatoria. La antibioticoterapia es esencial y como tratamiento único tiene como objetivo disminuir los costos y la morbilidad asociada a la cirugía; por tanto, actualmente el tratamiento adecuado de esta enfermedad es controversial y dependerá de los protocolos de actuación establecidos, el estado del paciente y los recursos disponibles(AU)
ABSTRACT The objective of this work is to study in depth the different cognitive aspects about the new evidences concerning the treatment of acute appendicitis and to compare the results obtained with the different surgical techniques currently used and the conservative treatment. A bibliographic review was carried out and articles were chosen from the electronic sources Web of Science, Scielo, Elsevier, PubMed, Medline, and Google, published in this century in Spanish and in English. Appendectomy by laparotomy has always been the gold standard for the treatment of acute appendicitis. In 1982, laparoscopic access was introduced, which has proven safe and efficient as conventional access. In 2004, endoscopic surgery through natural orifices was used; in 2007, it was performed by a single port, and in 2015, through retrograde endoscopy. The evolution of the clinical picture is variable so strategies have been proposed such as ambulatory surgery, conservative treatment followed or not by interval surgery, in order to avoid unnecessary interventions with morbidity and mortality similar to those performed with urgency. Appendectomy by laparotomy or laparoscopy is still the golden standard of the treatment of acute appendicitis, although laparoscopic access is required, new invasive techniques and outpatient surgery have emerged. Antibiotic therapy is essential and, as a single treatment, aims to reduce costs and morbidity associated with surgery; therefore, the adequate treatment of this disease is currently controversial and will depend on the established protocols of action, patient condition, and the available resources(AU)

ABSTRACT
Since the introduction of endoscopic submucosal dissection (ESD) in China in 2006, endoscopic minimally invasive treatment has experienced a booming development for more than 10 years, and its indications are gradually being expanded from inside the lumen to outside the lumen, from the superficial layer to the deep layer, from organic diseases to functional diseases. This article summaries the development of endoscopic minimally invasive resection in the past 10 years, from the perspective of mucosa, submucosa, muscularis, serosal and even extraluminal lesions, respectively, to introduce the role of endoscopic minimally invasive treatment. For mucosal lesions, ESD has become a first-line treatment for early gastric cancer; endoscopic treatment of colorectal lesions is still controversial in Europe and the United States, but is gradually being accepted. For submucosal tumors(SMT), the Expert Consensus for Endoscopic Diagnosis and Treatment of Submucosal Tumors in China (version 2018) was published in 2018, and the principles and related technical rules for gastrointestinal SMT have been highlighted. For serosal and even extraluminal lesions, natural orifice transluminal endoscopic surgery (NOTES) and tunnel endoscopic surgery, mainly including endoscopic myotomy (POEM) and endoscopic transmucosal tunneling tumor resection (STER), showed potential for development in preliminary studies, and showed good results in cholecystectomy, appendectomy, achalasia, gastroparesis and even extra-gastrointestinal tumor resection. This article describes the various endoscopic treatment techniques, and looks into their application prospects and future challenges.
ABSTRACT
In recent years,due to the coming of aging society,pelvic floor dysfunction(PFD)has gradually become one of the research hotspots in the field of obstetrics and gynecology worldwide.At present,surgery is the preferred treatment for moderate to severe PFD patients. With the development of minimally invasive surgery technology and the renewal of minimally invasive concept,PFD treatment options have been improved continuously. Natural orifice transluminal endoscopic surgery has been applied to gynecological surgery because of its fast recovery,slight pain and being without abdominal incision. Although the development of minimally invasive surgery provides more surgical options,different surgical methods have their advantages and disadvantages,and they should be controlled.Therefore,the age,symptoms,signs,medical history and general condition of the patients should be comprehensively evaluated to achieve the best therapeutic effect.
ABSTRACT
Minimally invasive treatment is of great significance to gynecological tumors. Laparoendoscopic single-site surgery(LESS)and natural orifice transluminal endoscopic surgery(NOTES)are recent advances in the field of minimally invasive treatment. At present,a variety of gynecological benign surgery can be managed by LESS or NOTES surgery,and achieved good clinical results. Operation for gynecologic malignancies are complicated,and LESS and NOTES surgery are still controversial for the treatment of gynecologic malignancies. At present,domestic and foreign scholars have made some useful attempts to apply NOTES surgery to malignant tumors.Preliminary data have confirmed the feasibility of these procedure,but due to the small operating space,the operation is difficult,and the operation skills still need to be developed.Based on the experience of our hospital's initial exploration,this article briefly explains the current situation,advantages,difficulties and technical experience in the application of NOTES surgery for gynecological malignancies.

ABSTRACT
OBJECTIVE: To study the efficacy of transvaginal natural orifice transluminal endoscopic surgery(vNOTES)sacrocolpopexy in the treatment of pelvic organ prolapse(POP).METHODS: From June 2017 to September 2018,33 POP patients who underwent vNOTES sacrocolpopexy in the Third Affiliated Hospital of Guangzhou Medical University were collected.The operative time,blood loss and postoperative complications were recorded to evaluate the safety of the operation.After regular follow-up,POP-Q was used to objectively evaluate the effect of surgery,and PFIQ-7 was used to evaluate the recovery effect.RESULTS: In this group,3 of 33 cases were converted to transumbilical laparoscopy,and in the remaining 30 cases the surgery was successfully completed.The operation time was(184.97±41.91)min,and mean estimated blood loss was(28.33±18.77)mL.No complications such as exposure or infection of mesh were found after operation.The POP-Q indicators were significantly improved in 1,3,6 months after surgery(P<0.05),and the quality of life was better after operation than before(P<0.05).CONCLUSION: vNOTES is a feasible and safe approach for sacrocolpopexy with positive short-term efficacy in the treatment of POP.
ABSTRACT
ABSTRACT Abscesses are a rare complication of transanal minimally invasive surgery and transanal endoscopic micro surgery. Reported cases have been in the rectal and pre-sacral areas and have been managed with either antibiotics alone or in conjunction with laparotomy and diverting colostomy. We report a case of a large retroperitoneal abscess following a Transanal minimally invasive surgery full thickness rectal polyp excision. The patient was successfully managed conservatively with antibiotics and a percutaneous drain. Retroperitoneal infection should be included in a differential diagnosis following a Transanal minimally invasive surgery procedure as the presentation can be insidious and timely intervention is needed to prevent further morbidity.
RESUMO Os abscessos são uma complicação rara da cirurgia de ressecção transanal minimamente invasiva (TAMIS) e da micro cirurgia endoscópica transanal (TEMS). Os casos notificados foram nas áreas rectal e pré-sacral e foram administrados com antibióticos isoladamente ou em conjunto com laparotomia e desvio de colostomia. Relatamos um caso de grande abscesso retroperitoneal após uma excisão de pólipo retal de espessura total TAMIS. O paciente foi tratado com sucesso com a administração de antibióticos e drenagem percutânea. Para prevenir mais morbidade é necessária incluir a infecção retroperitoneal no diagnostico diferencial após um procedimento TAMIS onde a apresentação pode ser insidiosa e a intervenção atempada.

ABSTRACT
There have been an evolutionary development with respect to the resection modality for the treatment of the gastric neoplasms such as gastric subepithelial tumors (SETs) or early gastric cancers (EGCs). Hybrid natural orifice transluminal endoscopic surgery (hybrid NOTES) played a central role in the process of development. In the earlier period, the non-exposure type hybrid NOTES such as laparoscopy and endoscopy cooperative surgery (LECS), endoscope-assisted wedge resection (EAWR), and laparoscopy-assisted endoscopic full-thickness resection (LAEFTR) has been introduced by several investigators. However, a concern about a spillage of gastric content including the tumor cells has been continuously raised among the clinicians. Accordingly, the non-exposure type hybrid NOTES such as combination of laparoscopic and endoscopic approaches to neoplasia with a non-exposure technique (CLEAN-NET), non-exposed endoscopic wall-inversion surgery (NEWS), and hybrid neo-endoscopic full-thickness resection (hybrid neo-EFTR) have been developed to the clinicians. Although most of studies about hybrid NOTES for the treatment of the gastric neoplasms have a small number of patients and require further validations, those are enough to receive our attention. Here, we describe and summarize the development process of the innovative resection methods for gastric neoplasms using hybrid NOTES approach.
