This ENETS guidance paper, developed by a multidisciplinary working group, provides an update on the previous colorectal guidance paper in a different format. Guided by key clinical questions practical advice on the diagnosis and management of neuroendocrine tumours (NET) of the caecum, colon, and rectum is provided. Although covered in one guidance paper colorectal NET comprises a heterogeneous group of neoplasms. The most common rectal NET are often small G1 tumours that can be treated by adequate endoscopic resection techniques. Evidence from prospective clinical trials on the treatment of metastatic colorectal NET is limited and discussion of patients in experienced multidisciplinary tumour boards strongly recommended. Neuroendocrine carcinomas (NEC) and mixed neuroendocrine non‐neuroendocrine neoplasms (MiNEN) are discussed in a separate guidance paper. [ABSTRACT FROM AUTHOR]

The management of postoperative bleeding, after gastric endoscopic submucosal dissection (ESD), has become particularly important because of the recent increase in antithrombotic use. Endoscopic shielding with polyglycolic acid (PGA) sheets has been shown to be effective. However, shrinkage and early displacement of the sheet remain challenges. This study aimed to determine the efficacy and safety of our developed method, named wafer paper and ring-mounted PGA sheet (WaRP). Twenty-four patients with antithrombotic uptake who underwent the WaRP method following gastric ESD were retrospectively examined. This involved the delivery of a PGA sheet wrapped in wafer paper with ring-thread, and its fixation on the gastric floor using hemoclips. The primary outcome was the technical success rate of the WaRP, and several secondary outcomes were evaluated. The technical success rate of WaRP was 100%. The procedure lasted a mean of 10.5 min (SD 6.7 min). The prevalence of complete retention at follow-up endoscopy was 83.3% (20/24). There were no WaRP-associated complications, but post-ESD hemorrhage occurred in two patients undergoing hemodialysis (8.3%). The WaRP method is a simple and reliable means of PGA sheet delivery and placement that reduces the incidence of post-ESD hemorrhage. [ABSTRACT FROM AUTHOR]

Background: Robotics represents the most technologically advanced approach in minimally invasive surgery (MIS). Its application in general surgery has increased progressively, with some early experience reported in emergency settings. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a systematic review of the literature to develop consensus statements about the potential use of robotics in emergency general surgery. Methods: This position paper was conducted according to the WSES methodology. A steering committee was constituted to draft the position paper according to the literature review. An international expert panel then critically revised the manuscript. Each statement was voted through a web survey to reach a consensus. Results: Ten studies (3 case reports, 3 case series, and 4 retrospective comparative cohort studies) have been published regarding the applications of robotics for emergency general surgery procedures. Due to the paucity and overall low quality of evidence, 6 statements are proposed as expert opinions. In general, the experts claim for a strict patient selection while approaching emergent general surgery procedures with robotics, eventually considering it for hemodynamically stable patients only. An emergency setting should not be seen as an absolute contraindication for robotic surgery if an adequate training of the operating surgical team is available. In such conditions, robotic surgery can be considered safe, feasible, and associated with surgical outcomes related to an MIS approach. However, there are some concerns regarding the adoption of robotic surgery for emergency surgeries associated with the following: (i) the availability and accessibility of the robotic platform for emergency units and during night shifts, (ii) expected longer operative times, and (iii) increased costs. Further research is necessary to investigate the role of robotic surgery in emergency settings and to explore the possibility of performing telementoring and telesurgery, which are particularly valuable in emergency situations. Conclusions: Many hospitals are currently equipped with a robotic surgical platform which needs to be implemented efficiently. The role of robotic surgery for emergency procedures remains under investigation. However, its use is expanding with a careful assessment of costs and timeliness of operations. The proposed statements should be seen as a preliminary guide for the surgical community stressing the need for reevaluation and update processes as evidence expands in the relevant literature.

Opioid misuse is a widespread public health problem, and opioids are often prescribed in the dental environment. These recommendations provide alternatives to opioids to reduce or eliminate dental procedure–related acute pain. A multidisciplinary working group developed these clinical recommendations to specifically address procedure-related acute pain. These recommendations, which are based on published peer-reviewed research and guidelines, include therapies used before, during, and after dental procedures. When evidence is not definitive, the best practices, which are based on experts' consensus, are included. The recommendations are not intended to be exhaustive. These recommendations are a summary of the evidence and best practices for opioid alternatives to treat acute pain related to dental procedures. Dental providers should prioritize opioid stewardship when managing procedure-related pain with strategies such as thorough preprocedure pain assessment, minimally invasive techniques, preemptive analgesia, intraprocedure pain management, and appropriately selected postprocedure pharmacologic therapy. These recommendations are a concise resource for clinical providers. It is important to address patients' procedure-related pain, using nonopioids whenever possible. Alternatives are outlined, allowing providers to make informed decisions. [ABSTRACT FROM AUTHOR]

This study is an analysis of the 100 most cited articles in mitral valve surgery. A bibliometric analysis is a tool to evaluate research performance in a given field. It uses the number of times a publication is cited by others as a proxy marker of its impact. The most cited paper Carpentier et al. discusses mitral valve repair in terms of restoring the geometry of the entire valve rather than simply narrowing the annulus (Carpentier, J Thorac Cardiovasc Surg 86:23-37, 1983). The first successful mitral valve repair was performed by Elliot Cutler at Brigham and Women's Hospital in 1923 (Cohn et al., Ann Cardiothorac Surg 4:315, 2015). More recently percutaneous and minimally invasive techniques that were originally designed as an option for high risk patients are being trialled in other patient groups (Hajar, Heart Views 19:160-3, 2018). Comparison of percutaneous method with open repair represents an expanding area of research (Hajar, Heart Views 19:160-3, 2018). This study will analyse the top 100 cited papers relevant to mitral valve surgery, identifying the most influential papers that guide current management, the institutions that produce them and the authors involved.

Background and Objectives: Transgender people are defined as individuals whose gender identity does not entirely match their sex assigned at birth. Gender surgery typically represents the conclusive and irreversible step in the therapeutic process, especially for the impact on the reproductive sphere. The increased awareness of gender dysphoria and the expanding array of medical and surgical options, including minimally invasive techniques, contribute to the gradual increase in the social impact of transgender surgery. There are several surgical techniques for "gender assignment", such as vaginal, laparotomic, laparoscopic, and robotic, and the novel approach of vaginal natural orifice transluminal endoscopic surgery to perform a hysterectomy and bilateral salpingo-oophorectomy (BSO). The purpose of this review is to assess the various surgical approaches (hysterectomy and salpingo-oophorectomy) for gender reassignment in order to determine the best option in clinical practice for the female-to-male population in terms of surgical outcomes such as operative time, surgical complication, hospital discharge, postoperative pain, and bleeding. Materials and Methods: This systematic review includes studies from 2007 to 2024. Special consideration was given to articles documenting the characteristics and management of female-to-male reassignment surgery. Finally, eight papers were included in this review. Results: The literature analysis considered surgical techniques ranging from traditional surgery to innovative methods like vaginal natural orifice transluminal endoscopic surgery and robotic-assisted laparoscopic hysterectomy. Vaginal natural orifice transluminal endoscopic surgery and the robotic approach offer potential benefits such as reduced postoperative pain and shorter hospital stays. While vaginal natural orifice transluminal endoscopic surgery may encounter challenges due to narrow access and smaller vaginal dimensions, robotic single-site hysterectomy may face instrument conflict. Conclusions: The conventional laparoscopic approach remains widely used, demonstrating safety and efficacy. Overall, this review underscores the evolving landscape of surgical techniques for gender affirmation and emphasizes the necessity for personalized approaches to meet the specific needs of transgender patients.

Endoscopic endonasal surgery of the skull base (EESSB) is now well established as an alternate surgical technique/approach for the treatment of skull base pathology but is not universally practiced at all institutions that perform skull base surgery. Skull base surgeons are encouraged to share the white paper with coders and insurance companies to promote improved understanding and better coding practices. [Extracted from the article]

The popularity of minimally invasive surgery for lumbar spinal stenosis (LSS) has been steadily increasing worldwide. This study aims to conduct a comprehensive bibliometric analysis to identify global trends and hotspots in the research related to this surgical approach.Methods: Select articles related to the field that were retrieved from the Web of Science Core Collection (WoSCC) between January 1, 1993 and December 31, 2022. Visualization of networks and in-depth bibliometric analyses, including the number of publications, countries/regions, institutions, journals, authors, keywords, and references, were conducted using VOSviewer and CiteSpace software.Results: A total of 1197 papers were identified over a three-decade period, with the highest production year being 2022, which saw 171 papers published. The most prolific countries/regions were the United States (279) and Harvard Medical School (59). Among journals, Spine (3289 citations) was the most cited, while World Neurosurgery (98 publications) had the highest number of publications. Lewandrowski, Kai-Uwe (29 publications) wrote the most articles, and Ahn, Y (239 citations) ranked first among cited authors. The most frequently used keyword was "discectomy", but recent years have shown a strong emergence of keywords such as "microendoscopic decompressive laminotomy", "foraminotomy" and "classification".Conclusion: The United States and China have emerged as leaders in the field of minimally invasive surgery for LSS. Endoscopic spinal surgery is recognized as a critical approach, with ongoing research focused on indications, potential complications, minimally invasive anatomical approaches, and outcomes. Furthermore, there is a strong emphasis on optimizing the surgical process, which has become a trending and hot spot in current research. The improvement of surgical techniques is at the forefront of advancements in this field. [ABSTRACT FROM AUTHOR]

While primarily observed in adults, this case contributes valuable insights into the manifestation and management of this benign salivary gland tumor within the pediatric population. This paper reports the first documented case of sinonasal pleomorphic adenoma in pediatric otolaryngology, presenting a unique perspective on this rare nasal tumor in a 9-year-old boy. The patient presented with progressive nasal obstruction and epistaxis and underwent a smooth endoscopic resection of a 2-cm pleomorphic adenoma on the right anterior nasal septum. The subsequent discussion covered background, histology, imaging, and management strategies. Surgical removal with clear margins, particularly through the endoscopic approach, emerged as the primary and successful treatment method, minimizing morbidity and reducing recurrence risk. Long-term clinical surveillance is recommended due to an estimated 8.8% recurrence rate. In conclusion, this paper explains the challenges and solutions in diagnosing and treating sinonasal pleomorphic adenomas in children. It emphasizes the critical importance of early diagnosis, precise surgical intervention, and continuous monitoring, which are essential for achieving optimal patient outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: In this review, first, the history of EUS-guided biliary drainage (EUS-BD) is summarized. In the following chapters controversies arising from various approaches and challenges in EUS-BD, EUS-guided gallbladder drainage (EUS-GBD) and alternatively performed procedures are discussed from different points of view on the background of the available evidence. In addition, for all topics arguments in favor and against the techniques are described and reflected. The topics include "Why do we need procedures other than ERCP?"; "Should EUS-BD and ERCP be performed by the same operator?"; rendezvous techniques, including "Should rendezvous be used first?" and "Which rendezvous route should be used?"; percutaneous transhepatic cholangiography and biliary drainage (PTBD); "Should PTBD and EUS-BD be performed by the same physician?"; "Do we need cystotomes?"; "Do we need bougies?"; "Are all EUS needles the same for EUS-BD?"; "Plastic or metal stents?"; and adverse events. In this 14th document in a series of papers entitled "Controversies in Endoscopic Ultrasound" we discuss various aspects of EUS-guided biliary drainage that are debated in the literature and in practice. Endoscopic retrograde cholangiography is still the reference technique for therapeutic biliary access, but EUS-guided techniques for biliary access and drainage have developed into safe and highly effective alternative options. However, EUS-guided biliary drainage techniques are technically demanding procedures for which few training models are currently available. Different access routes require modifications to the basic technique and specific instruments. In experienced hands, percutaneous transhepatic cholangiodrainage is also a good alternative. Therefore, in this paper, we compare arguments for different options of biliary drainage and different technical modifications. [ABSTRACT FROM AUTHOR]

Background : Patients affected by cleft lip and palate have a characteristic nasal deformity; however, the treatment timeline varies amongst providers. There has been a shift from a more conservative approach to earlier intervention in order to allow for more normal development of the nose. Form, function, and future development all must be considered. For this reason, this investigation was undertaken to present the current literature available on the effects to all aspects of primary septoplasty in the cleft nasal deformity. Design : An initial list of 222 papers was identified, and it was determined that 16 papers fit the inclusion criteria. Studies were included in which the initial age of operation for the majority of patients was between 3 and 12 months and in which patients underwent septal repositioning at the time of cleft lip repair. These papers were all reviewed by a single author initially, and the results recorded. All results were then verified by a second author for accuracy and completeness. Results : Symmetry was found to be improved by primary septoplasty. Growth was not found to be impaired in any study; data was insufficient to indicate that growth was improved. Obstruction was improved as determined both by imaging, endoscopy, and patient survey. Finally, reoperation rates occurred at an acceptable rate not exceeding that of primary rhinoplasty without septoplasty. Conclusion : Primary septoplasty leads to better aesthetic symmetry and function of the cleft nose without impairing growth. This change is maintained into adulthood often without the need for revisionary surgery. [ABSTRACT FROM AUTHOR]

Simple Summary: Patients with pituitary tumors and other masses at the bottom of the skull are at risk of brain infection and leaks of the fluid surrounding the brain when the tumor is removed surgically. To prevent these types of complications, surgeons have developed techniques to patch the surgical area with normal tissue taken from other parts of the body. In the past, this tissue was taken from the head, neck, and shoulder regions. Newer techniques allow the entire surgery to occur within the nose, resulting in fewer side effects and faster recovery. This includes taking normal tissue from within the nose to repair the base of the skull where the mass is removed. The nasoseptal flap is the most common method for this type of intranasal repair. In this paper, we describe the development and evolution of this surgical technique and discuss the impact that it has had on patient outcomes. The nasoseptal flap is a workhorse reconstructive option for anterior skull base defects during endonasal surgery. This paper highlights the versatility of the nasoseptal flap. After providing a brief historical perspective, this review will focus on the relevant primary literature published in the last ten years. We will touch upon new applications of the flap, how the flap has been modified to expand its reach and robustness, and some of the current limitations. We will conclude by discussing what the future holds for improving upon the design and use of the nasoseptal flap in anterior skull base reconstruction. [ABSTRACT FROM AUTHOR]

Blue nevus is a type of uncommon benign pigmented lesion in the skin or the mucosa of human body which is featured by pigmented dendritic melanocytes and spindled melanocytic cells. Sinonasal blue nevus is extremely rare. We reported a sinonasal blue nevus case with the background of pituitary adenoma, type 2 diabetes mellitus, and hypertension (including endoscopic and histological pictures). Further, the existing literature about blue nevus is reviewed. This paper puts a spotlight on the potential correlation between blue nevus with the endocrine system disorder and provides support for further experimental research. [ABSTRACT FROM AUTHOR]

The miniature serpentine robot can be applied to NOTES (Natural Orifice Transluminal Endoscopic Surgery). In this paper, a bronchoscopy application is addressed. This paper describes the basic mechanical design and control scheme of this miniature serpentine robotic bronchoscopy. In addition, off-line backward path planning and real-time and in situ forward navigation in this miniature serpentine robot are discussed. The proposed backward-path-planning algorithm utilizes the 3D model of a bronchial tree constructed from the synthetization of medical images such as images from CT (Computed Tomography), MRI (Magnetic Resonance Imaging), or X-ray, to define a series of nodes/events backward from the destination, for example, the lesion, to the original starting point, for example, the oral cavity. Accordingly, forward navigation is designed to make sure this series of nodes/events shall be passed/occur from the origin to the destination. This combination of backward-path planning and forward navigation does not require accurate positioning information of the tip of the miniature serpentine robot, which is where the CMOS bronchoscope is located. Collaboratively, a virtual force is introduced to maintain the tip of the miniature serpentine robot at the center of the bronchi. Results show that this method of path planning and navigation of the miniature serpentine robot for bronchoscopy applications works. [ABSTRACT FROM AUTHOR]

Background: Recent studies suggest that individuals who underwent noncurative endoscopic resection for gastric cancer may require additional surgery. We conducted a comprehensive systematic review and meta-analysis to investigate the risk of lymph node metastasis in these cases. Methods: We comprehensively examined relevant literature by extensively reviewing electronic databases such as PubMed, Cochrane Library, and Google Scholar. Subsequently, we analyzed clinicopathological outcomes and calculated pooled odds ratios and 95 percent confidence intervals using diverse effects models. Results: This analysis included 12 papers with 4808 individuals who underwent additional surgery after noncurative endoscopic resection for early gastric cancer. The results indicated significant associations between lymph node metastasis and submucosal invasion (Odd ratio 2.04, 95% (CI): 1.58-2.63, I 2 = 88.7%; p<0.001), vertical margin (Odd ratio 6.11, 95% (CI): 1.94-19.23, I 2 = 0%; p<0.001), lymphatic invasion (Odd ratio 10.02, 95% (CI): 7.57-13.27, I 2 = 92%; p<0.000), and vascular invasion (Odd ratio 7.11, 95% (CI): 5.49-9.22, I 2=92%; p<0.000). Conclusion: When choosing factors for surgical treatment, it is essential to thoroughly consider the invasion of lymph nodes, vascular system, submucosa, and positive vertical margin.

The study aimed to make a bibliometric analysis of the current research situation in unilateral biportal endoscopy/biportal endoscopic spinal surgery (UBE/BESS). Research data sets were acquired from the Web of Science database. The study chosed "biportal endoscopic spinal surgery" OR "two portal endoscopic spinal surgery" OR "percutaneous biportal endoscopic decompression" OR "unilateral biportal endoscopy" OR "irrigation endoscopic discectomy" as the search terms. The literature search was limited to articles published before March 5, 2021. We only included original articles and reviews. VOS viewer and Citespace software were used to analyze the data and generate visualization knowledge maps. Annual trend of publications, distribution, H‐index status, co‐authorship status, and research hotspots were analyzed. A total of 74 publications met the requirement. The sum number of citations was 31,204, in which 19,336 were no self‐citations. The average citation of all the papers was 21.84 times. The H‐index of all the publications was 85. South Korea's total number of articles was far higher than that of other countries and regions (61, 82.4%), followed by United Arab Emirates, Egypt, and Peoples Republic of China (three, ranking second, accounting for 12.2% of the total). For the most productive authors, Choi ranked first with 21 articles, Kim ranked second with 16 articles, and Heo ranked third with 12 articles. The journal with the greatest number of publications was World Neurosurgery, with a total of 18 (39.1%) papers. Clinics in Orthopedic Surgery ranked second with six (13.0%) papers. In third place, there were fix articles published by Asian Spine Journal and Neurospine, accounting for 21.8% of the total articles. These top three journals accounted for 73.9% of all the papers. Spondylolisthesis and endoscopic decompression were the research hotspots in recent years. The number of publications has showed an upward trend with a stable rise in recent years. South Korea is the country with the highest productivity, not only in quality, but also in quantity. Barun Hosp and Leon Wiltse Mem Hosphave published most articles. Choi is the most productive author. World Neurosurgery is the most productive journal. Spondylolisthesis and endoscopic decompression are the research hotspots in recent years. Indeed, this study provides new insight into the growth and development of UBE/BESS. [ABSTRACT FROM AUTHOR]

Background: This paper reports the first case of simultaneous bilateral cochlear implant surgery performed exclusively with a three-dimensional exoscope. It also discusses the optimum operative set-up and the feasibility of three-dimensional exoscopic ear surgery as an alternative to the microscope. Method: The Vitom three-dimensional exoscope system (Karl Storz) was used. Results: The surgery was successfully completed, with no peri-operative complications. Both the operation time and the surgical outcome for the patient were comparable with the previous cochlear implant surgical procedures performed in our centre using the conventional operating microscope. Conclusion: This paper demonstrates that exclusive use of the three-dimensional exoscope is a viable alternative to the operating microscope for selected otological cases. It is clear that the three-dimensional exoscopic technique is potentially very promising for future surgical procedures, provided that cases are selected carefully to prevent compromising exposure, efficiency or patient safety.

Objective: To assess the current standard of consent for functional endoscopic sinus surgery and determine whether it complies with the law following the Montgomery ruling. Methods: Ten complications following functional endoscopic sinus surgery were identified as common or serious from a literature search. Using questionnaires, ENT surgeons were asked which of these complications they discussed with patients, and patients were asked how seriously they regarded those risks using a five-point Likert scale. Results: Consent practice from 21 ENT surgeons and data from 103 patients were analysed. The 'reasonable patient' would expect to be consented for all risks, except for pain, and scarring or adhesions. Most ENT surgeons would routinely discuss all risks that were considered significant, except for facial paraesthesia (29 per cent) and damage to the nasolacrimal duct (24 per cent). A negative change in sense of smell was not mentioned by 29 per cent of surgeons. Conclusion: This paper demonstrates that the current consent process for functional endoscopic sinus surgery is likely to be substandard medicolegally. [ABSTRACT FROM AUTHOR]

Objective: Acromegaly is a condition characterized by an overproduction of growth hormone which infers high morbidity and mortality if left untreated. The objective of this review is to analyse and appraise the current evidence for the generalized use of preoperative medications and the various surgical approaches as described in the literature. Design: A thorough search from MEDLINE via PubMed, EMBASE, and Cochrane Library has been performed which identified a total of 37 papers. Conclusion: The preoperative use of somatostatin receptor agonists (SAs) in acromegaly is a controversial topic with current guidelines suggesting against their generalized routine use. Most authors noticed an insignificant long‐term remission of acromegaly when given SAs compared with nil preoperative therapy, except for invasive macroadenomas as SAs have been found to reduce the tumour volume and aid towards the total resection of the adenoma. Furthermore, according to the evidence available, endoscopic transsphenoidal surgery is the optimum method for hypophysectomy in terms of its remission and safety profile. [ABSTRACT FROM AUTHOR]

Patients with familial adenomatous polyposis (FAP) develop early colorectal adenomas and if left untreated, progression to cancer is an inevitable event. Prophylactic surgery does not prevent further development of cancer in the rectal remnant, rectal cuff in patients with ileal pouch anal anastomosis (IPAA) and even on the ileal mucosa of the pouch body. The aim of this review is to assess long-term rates of cancer and adenoma development in patients with FAP after prophylactic surgery and to summarise current recommendations for endoscopic management and surveillance of these patients. A systematic literature search of studies from January 1946 through to June 2023 was conducted using the PRISMA checklist. The electronic database PubMed was searched. Fifty-four papers involving 5010 patients were reviewed. Cancer rate in the rectal remnant was 8.8–16.7% in the western population and 37% in the eastern population. The cumulative risk of cancer 30 years after surgery was 24%. Mortality due to cancer in the rectal remnant is 1.1–11.1% with a 5-year survival rate of 55%. The adenoma rate after primary IPAA was 9.4–85% with a cumulative risk of 85% 20 years after surgery and a cumulative risk of 12% for advanced adenomas 10 years after surgery. Cumulative risk for adenomas after ileorectal anastomosis (IRA) was 85% after 5 and 100% after 10 years. Adenomas developed more frequently after stapled (33.9–57%) compared to hand-sewn (0–33%) anastomosis. We identified reports of 45 cancers in patients after IPAA of which 30 were in the pouch body and 15 in the rectal cuff or at the anastomosis. There was a significant incidence of cancer and adenomas in the rectal remnant and ileal pouch of FAP patients during the long-term follow-up. Regular endoscopic surveillance is recommended, not only in IRA patients, but also in pouch patients after proctocolectomy. [ABSTRACT FROM AUTHOR]

BACKGROUND. Endoscopic sinus surgery (ESS) has revolutionized the treatment of nasal and paranasal sinus conditions, offering minimally invasive techniques with improved patient outcomes. However, ESS can be challenging, lengthy, and physically demanding. This article presents a comprehensive overview of factors to consider before and during ESS to enhance surgical ease and patient comfort. MATERIAL AND METHODS. The paper is a literature review sustaining a point of view on the factors influencing the outcome of endoscopic sinus surgery. RESULTS. Preoperative considerations encompass a thorough assessment of surgical indications, weighing against medical alternatives as per guidelines. Attention to patient comorbidities, medication management and infection control are paramount. Intraoperatively, collaboration with anesthesiologists is crucial for optimizing patient stability and minimizing complications. Ergonomic considerations, patient positioning and surgical environment optimization contribute to surgeon comfort and procedural efficiency. The surgical procedure entails meticulous preparation of the nasal cavity, preservation of anatomical structures, and adherence to standardized techniques. The sphenoethmoidectomy is described as a sequential five-door procedure, emphasizing anatomical landmarks and meticulous dissection techniques. Hemostasis and the judicious use of powered shavers play pivotal roles in minimizing bleeding and optimizing tissue removal. Navigation systems offer additional support, particularly in complex cases or revision surgeries. CONCLUSION. ESS requires meticulous planning, technical proficiency, and interdisciplinary collaboration to optimize outcomes. Anticipation and adherence to standardized protocols are paramount in navigating the challenges of ESS, ultimately enhancing surgical ease and patient comfort. [ABSTRACT FROM AUTHOR]

Simple Summary: Autoimmune atrophic gastritis can lead to serious conditions, including malabsorption and vitamin deficiencies, that may cause anemia, neurological disorders, and gastric malignancies. This paper provides recent evidence on the pathogenesis, diagnosis, clinical presentation, risk of malignancies, endoscopic surveillance, and treatment of autoimmune atrophic gastritis. This review provides a valuable update for healthcare professionals and researchers, and the findings may help improve the diagnosis and management of patients with autoimmune atrophic gastritis, leading to improved outcomes and shaping future research directions. Autoimmune atrophic gastritis (AAG) is a chronic condition characterized by the presence of atrophy in the oxyntic mucosa due to anti-parietal cell antibodies. This review provides a comprehensive and up-to-date overview of autoimmune atrophic gastritis, reporting recent evidence on epidemiology, pathogenesis, diagnosis, clinical presentation, risk of malignancies, and management. The prevalence of AAG has been estimated at between 0.3% and 2.7% in the general population. The diagnosis of AAG is based on a combination of the serologic profile and the histological examination of gastric biopsies. Patients with AAG are often asymptomatic but can also have dyspeptic or reflux symptoms. The atrophy of the oxyntic mucosa leads to iron and vitamin B12 malabsorption, which may result in anemia and neurological affections. Autoimmune atrophic gastritis is associated with an increased risk of type I neuroendocrine tumors (NETs) and gastric cancer, with an incidence rate of 2.8% and 0.5% per person/year, respectively. Management is directed to reinstate vitamins and iron and to prevent malignancies with endoscopic surveillance. In conclusion, atrophic autoimmune gastritis is an infrequent condition, often asymptomatic and misdiagnosed, that requires an early diagnosis for appropriate vitamin supplementation and endoscopic follow-up for the early diagnosis of NETs and gastric cancer.

Recent developments in deep learning have enabled data-driven algorithms that can reach human-level performance and beyond. The development and deployment of medical image analysis methods have several challenges, including data heterogeneity due to population diversity and different device manufacturers. In addition, more input from experts is required for a reliable method development process. While the exponential growth in clinical imaging data has enabled deep learning to flourish, data heterogeneity, multi-modality, and rare or inconspicuous disease cases still need to be explored. Endoscopy being highly operator-dependent with grim clinical outcomes in some disease cases, reliable and accurate automated system guidance can improve patient care. Most designed methods must be more generalisable to the unseen target data, patient population variability, and variable disease appearances. The paper reviews recent works on endoscopic image analysis with artificial intelligence (AI) and emphasises the current unmatched needs in this field. Finally, it outlines the future directions for clinically relevant complex AI solutions to improve patient outcomes. [ABSTRACT FROM AUTHOR]

Navigation brought about a tremendous improvement in functional endoscopic sinus surgery (FESS). When upgraded accordingly, FESS becomes navigated endoscopic sinus surgery (NESS). Indications for intraoperative use of navigation can be broadened to almost any FESS case. NESS in advanced sinus surgery is currently still not used routinely and requires systematic practice guidelines. The purpose of this paper is to report on commonly identified landmarks while performing advanced NESS according to evidence-based medicine (EBM) principles. This review paper has been assembled following PRISMA guidelines. A PubMed and Scopus (EMBASE) search on anatomical landmarks in functional endoscopic and navigated sinus surgery resulted in 47 results. Of these, only 14 (29.8%) contained original data, constituting the synthesis of best-quality available evidence. Anatomical landmarks are considered to be the most important points of orientation for optimal use of navigation systems during FESS surgery. The most commonly identified significant landmarks are as follows: (1) Maxillary sinus ostium; (2) Orbital wall; (3) Frontal recess; (4) Skull base; (5) Ground lamella; (6) Fovea posterior; (7) Sphenoid sinus ostium. Conclusions: Establishing common landmarks are essential in performing NESS. This is true for advanced and novice surgeons alike and offers a possibility to use navigation systems systematically, taking advantage of all the benefits of endoscopic navigated surgery.

Methods: All pertinent articles on endoscopic thyroidectomy were obtained from the Web of Science Core Collection Database. The data on the number of citations and publications, most prolific countries and institutions, significant authors and journals, top themes, and keywords were analyzed by Biblioshiny, CiteSpace, and VOSviewer. Results: There were 758 publications, all of that were found from 2013 to 2022. The output of the annual publication showed an upward trend. A series of cases report by Anuwong et al. published in 2016 received the most citations. The country with the most articles published articles was South Korea, and the two countries with the most collaboration were South Korea and the United States. The most productive journal was Surgical Endoscopy and Other Interventional Techniques. Dionigi G, Kim HY, and Anuwong A were the writers with the most articles published, the highest hand g-indices, and the strongest link strength, respectively. The keywords "endoscopic thyroidectomy", "surgical", "thyroidectomy", "robotic thyroidectomy", "experience", and others were most used. Conclusion: The innovative surgical technique, transoral endoscopic thyroidectomy vestibular approach (TOETVA), leaves no scars and produces optimal cosmetic results. However, the long-term oncologic results for thyroid cancer performed with this approach are still missing. This scientometric analysis can offer valuable insights into the present research standing and key focal points in this domain, enabling researchers to gain a precise understanding of the state-of-the-art research in this area.

Background: Choanal atresia is a congenital obstruction of the posterior nasal aperture. Endoscopic endonasal surgery has led to successful choanal atresia repair. This paper describes our surgical technique using septal mucosal flaps without the need for stenting. Methods: This study comprised a multicentre retrospective review of patient notes. A cross-over septal technique is described, whereby bilateral vertical mucosal incisions are made at the posterior third of the septum, and the atretic plate and posterior vomer are removed. One flap is pedicled superiorly and rotated over the bare skull base and sphenoid bone; the contralateral flap is pedicled inferiorly to cover the exposed vomer remnant and hard palate. Results: There were 12 patients from 2013 to 2020, aged 0.07–50 years, with a male to female ratio of 1:5. Ten patients had unilateral and two had bilateral choanal atresia. Nine patients had bony choanal atresia, with the remainder mixed. Conclusion: The cross-over technique for choanal atresia has low morbidity and 100 per cent success in our series. The use of mucoperiosteal flaps to cover exposed bone and minimal instrumentation to the lateral nasal wall reduce post-operative stenosis. [ABSTRACT FROM AUTHOR]

Objective: The study aims to assess the current development status of transforaminal full-endoscopic spine surgery (TFES) by exploring and analyzing the published literature to obtain an overview of this field and discover the evolution and emerging topics that are underrepresented. Methods: Using Bibliometrix, CiteSpace, and VOSviewer, we analyzed the bibliometric data selected from the Web of Science Core Collection between January 2002 and November 2022. The descriptive and evaluative analyses of authors, institutes, countries, journals, keywords, and references are compiled. The quantity of research productivity was measured by the number of publications that were published. A quality indicator was thought to be the number of citations. In the bibliometric analysis of authors, areas, institutes, and references, we calculated and ranked the research impact by various metrics, such as the h-index and m-index. Results: A total of 628 articles were identified in the field of TFES by the 18.73% annual growth rate of research on the subject from 2002 to 2022, constituting the documents are by 1961 authors affiliated with 661 institutions in 42 countries or regions and published in 117 journals. The USA (n = 0.20) has the highest international collaboration rate, South Korea has the highest H-index value (h = 33), and China is ranked as the most productive country (n = 348). Brown univ., Tongji univ., and Wooridul Spine represented the most productive institutes ranked by the number of publications. Wooridul Spine Hospital demonstrated the highest quality of paper publication. The Pain Physician had the highest h-index (n = 18), and the most cited journal with the earliest publication year in the area of FEDS is Spine (t = 1855). Conclusion: The bibliometric study showed a growing trend of research on transforaminal full-endoscopic spine surgery over the past 20 years. It has shown a significant increase in the number of authors, institutions, and international collaborating countries. South Korea, the United States, and China dominate the related areas. A growing body of evidence has revealed that TFES has leapfrogged from its infancy stage and gradually entered a mature development stage. [ABSTRACT FROM AUTHOR]

Navigation control skills of surgeons become very critical for surgical procedures. Strategies improving these skills are important for developing higher-quality surgical training programs. In this study, the underlying reasons of the navigation control effect on performance in a virtual reality-based navigation environment are evaluated. The participants' performance is measured in conditions: navigation control display and paper-map display. Performance measures were collected from 45 beginners and experienced residents. The results suggest that navigation display significantly improved performance of the participants. Also, navigation was more beneficial for beginners than experienced participants. The underlying reason of the better performance in the navigation condition was due to lower number of looks to the map, which causes attention shifts between information sources. Accordingly, specific training scenarios and user interfaces can be developed to improve the navigation skills of the beginners considering some strategies to lower their number of references to the information sources.

Objectives: This qualitative systematic review evaluates the evidence in support of the use of oral corticosteroids in patients undergoing sialendoscopy for the treatment of obstructive sialadenitis. Design: Qualitative systematic review. Methods: A literature search was conducted from January 1985 and September 2020. Inclusion criteria embraced peer-reviewed articles in which adult patients undergoing interventional sialendoscopy for obstructive salivary gland disease received oral corticosteroids. The results were initially screened based on title and abstract, and the remaining articles were reviewed for eligibility. Results: About 218 papers were selected by title and abstract, 96 were selected for full-text review, and 9 met the inclusion criteria. Eight published reports were retrospective observational studies and 1 was a prospective comparative study. Overall, the heterogeneity of clinical data stood out in this systematic review. The pooled success rate in the studies was 873/979 (89%). Only 5 studies described a rationale for oral corticosteroid use as part of the post-operative management. In 4 studies, a prednisone total daily dose of 40 to 50 mg was used. One study clearly showed a lower recurrence rate in patients who received oral steroids for more than 7 days in addition to sialendoscopy for management of ductal stenoses. Conclusion: This systematic review showed that most centers that prescribe oral corticosteroids after sialendoscopy are unaware of the specific results with this treatment. For ductal stenoses, only 1 paper clearly showed the benefits of oral corticosteroids after sialendoscopy but more high-quality evidence is required in the form of a comparative study or randomized controlled trial, with appropriate long-term follow up.
