Project description:Background and study aims Women remain underrepresented in gastroenterology, especially advanced endoscopy. Women represent 30 % of general gastroenterology fellows; yet in 2019, only 12.8 % of fellows who matched into advanced endoscopy fellowship (AEF) programs were women. Methods We administered a web-based survey to the program directors (PDs) of AEF programs that participated in the 2018-2019 American Society for Gastroenterology (ASGE) match. We assessed PD and program characteristics, in addition to perceived barriers and facilitators (scale 1-5, 5 = most important) influencing women pursuing AEF training. Results We received 38 (59.3 %) responses from 64 PDs. 15.8 % (6/38) of AEF PDs and 13.2 % (5/38) of endoscopy chiefs were women. By program, women represented 14.8 % (mean) ± 17.0 % (SD) of AEF faculty and 12.0 % (mean) ± 11.1 % (SD) of AEF trainees over the past 10 years. 47.4 % (18/38) programs reported no female advanced endoscopy faculty and 31.6 % (12/38) of programs have never had a female fellow. Percentage of female fellows was strongly associated with percentage of female AEF faculty (ß = 0.43, P < 0.001). Inflexible hours and call (mean rank 3.3 ± 1.1), exposure to fluoroscopy (2.9 ± 1.1), lack of women endoscopists at national conferences/courses (2.9 ± 1.1) and lack of female mentorship (2.9 ± 1.0) were cited as the most important barriers to recruitment. Conclusion We utilized a survey of AEF PDs participating in the ASGE match to determine program characteristics and identify contributors to gender disparity. Women represent a minority of AEF PDs, endoscopy chiefs, advanced endoscopy faculty and AEF trainees. Our study highlights perceived barriers and facilitators to recruitment, and emphasizes the importance of having female representation in faculty, and leadership positions in endoscopy.

Project description:During the last 10 years, microscope-integrated indocyanine green fluorescence (m-ICG) has been widely used for assessing real-time blood flow during aneurysm surgery. More recently, an endoscope-integrated indocyanine green fluorescence (e-ICG) has been adopted as a versatile tool during different endoscopic neurosurgical procedures. The purpose of the present report is to evaluate multimodal applications of e-ICG during different endonasal, intraventricular, aneurysm and brain tumor surgeries and provide technical nuances. In addition, we reviewed the literature and identified and compare several overlapping case series of patients treated via an endoscopic integrated indocyanine green fluorescence technique. A total of 40 patients were retrospectively evaluated. Patients were divided into four main groups: (1) endoscopic endonasal approaches (n = 14); (2) ventricular endoscopic approach including patients undergoing third ventriculostomy (n = 8) and tumor biopsy (n = 1); (3) aneurysms surgery (n = 9); and (4) brain parenchymal tumors (n = 8). All patients were successfully treated using the e-ICG dynamic endoscopic visualization, and there were no perioperative complications. Such unique features open up a promising field of applications beyond the use of m-ICG in different surgical field due to the longer duration of e-ICG fluorescence up to 35 ± 7 min. E-ICG represents a new and effective technique for longer real-time visualization of vascular structures preserving normal tissues and functions during different transcranial and endonasal approaches. As the technology and e-ICG resolution improves, the technique has the potential to become a critical tool for different applications in neurosurgery.

Project description:In general, gastroesophageal reflux disease (GERD) is diagnosed clinically based on typical symptoms and/or response to proton pump inhibitor treatment. Upper gastrointestinal endoscopy is reserved for patients presenting with alarm symptoms, such as dysphagia, odynophagia, significant weight loss, gastrointestinal bleeding, or anorexia; those who meet the criteria for Barrett's esophagus screening; those who report a lack or partial response to proton pump inhibitor treatment; and those with prior endoscopic or surgical anti-reflux interventions. Newer endoscopic techniques are primarily used to increase diagnostic yield and provide an alternative to medical or surgical treatment for GERD. The available endoscopic modalities for the diagnosis of GERD include conventional endoscopy with white-light imaging, high-resolution and high-magnification endoscopy, chromoendoscopy, image-enhanced endoscopy (narrow-band imaging, I- SCAN, flexible spectral imaging color enhancement, blue laser imaging, and linked color imaging), and confocal laser endomicroscopy. Endoscopic techniques for treating GERD include esophageal radiofrequency energy delivery/Stretta procedure, transoral incisionless fundoplication, and endoscopic full-thickness plication. Other novel techniques include anti-reflux mucosectomy, peroral endoscopic cardiac constriction, endoscopic submucosal dissection, and endoscopic band ligation. Currently, many of the new endoscopic techniques are not widely available, and their use is limited to centers of excellence.

Project description:ObjectivesFew reports have detailed improvements in the quality of colonoscopies with continuous training post-fellowship completion. We examined the changes in colonoscopy performance among trainees during our advanced endoscopy training program.MethodsScreening or surveillance colonoscopies performed by 11 trainees who participated in our 3-year advanced endoscopy training program between April 2015 and March 2020 were retrospectively analyzed. Quality and efficiency metrics of colonoscopies were evaluated annually.ResultsAltogether, 297, 385, and 438 colonoscopies were enrolled in the first, second, and third training years, respectively. The mean insertion times were 8.6, 7.6, and 6.9 min in the first, second, and third training years, respectively, with significant improvement from the first to second year (p = 0.03) and from the first to third year (p < 0.01). The adenoma detection rate, proximal adenoma detection rate, and mean number of adenomas per patient exhibited a tendency to improve annually; however, the difference was not significant. Polypectomy efficiency was 10.5%, 11.2%, and 13.0%, with significant improvements from the first to third year (p < 0.01) and from the second to third year (p = 0.02). Insertion time and polypectomy efficiency showed significant improvements, especially among trainees experienced with <500 colonoscopies.ConclusionsThrough our advanced endoscopy training program, there has been an improvement in the quality and efficiency of colonoscopy for trainees who have completed their fellowships, particularly those with <500 colonoscopies.

Project description:Malignant hilar biliary obstruction (MHO) is a medical challenge as regards both forming a correct diagnosis and its adequate management, in terms of treatment alternatives and palliative options. Surgical resection is the only curative treatment for the underlying disease, but the majority of patients are not suitable candidates because of an unresectable tumor or poor performance status. Biliary drainage (BD) can be achieved through the percutaneous transhepatic route or endoscopically, and the choice depends on a host of factors, including biliary anatomy and comorbidity of the patient. Though there is no consensus, the endoscopic approach is usually preferred over the former. Endoscopy can aid in both diagnosis (collection of histological as well as cytological samples, direct visualization of suspected malignant pathology, or use of endoscopic ultrasound [EUS] for evaluation and locoregional staging), and in achieving internal BD. Advances in the development of various stents, accessories and, more recently, the use of EUS have in fact further expanded its application in MHO management. The choice of stents to be used (type, make, and number), palliation methods, deployment techniques and the use of local ablative strategy are still evolving and require more data. The complexity of management of MHO mandates that each patient should receive a "personalized approach", all the way from establishing a diagnosis until final treatment, with the help of a multidisciplinary team effort. Herein, we provide a comprehensive literature review of the current role of endoscopy for MHO, according to its applications in various clinical settings.

Project description:Capsule endoscopy (CE) has been increasingly utilised in recent years as a minimally invasive tool to investigate the whole gastrointestinal (GI) tract and a range of capsules are currently available for evaluation of upper GI, small bowel, and lower GI pathology. Although CE is undoubtedly an invaluable test for the investigation of small bowel pathology, it presents considerable challenges and limitations, such as long and laborious reading times, risk of missing lesions, lack of bowel cleansing score and lack of locomotion. Artificial intelligence (AI) seems to be a promising tool that may help improve the performance metrics of CE, and consequently translate to better patient care. In the last decade, significant progress has been made to apply AI in the field of endoscopy, including CE. Although it is certain that AI will find soon its place in day-to-day endoscopy clinical practice, there are still some open questions and barriers limiting its widespread application. In this review, we provide some general information about AI, and outline recent advances in AI and CE, issues around implementation of AI in medical practice and potential future applications of AI-aided CE.

Project description:IntroductionUnequal female representation in the field of advanced therapeutic endoscopy (ATE) has been recently highlighted in the United States. Previous attempts to determine the barriers to entry into the career have reported a lack of mentorship, patriarchy, inflexible hours/calls and exposure to fluoroscopy. Canadian trainee exposure to ATE and differences in experience between men and women is unknown.ObjectivesWe sought to determine the barriers to pursuing a career in ATE, specifically focussing on the perspectives of Canadian female gastroenterology fellows.MethodsAn online survey was developed and distributed to Canadian gastroenterology fellows enrolled in Royal College-accredited programs in 2021-2022.ResultsResponses were received from gastroenterology fellows at 12 of the 14 Canadian programs. The response rate was 46% (n = 42, 16 female respondents and 26 male respondents). An equal proportion of male (42%, n = 11) and female (38%, n = 6) trainees indicated interest in a career in ATE. Thirty-eight per cent (n = 6) of female trainees felt that they had inadequate mentorship opportunities/role models within ATE, in comparison to 4% (n = 1) of males (P = .004). Furthermore, 19% (n = 3) of females felt that this lack of mentorship/role models was a primary deterrent from pursuing ATE as a career, in comparison to 0% of males (P = .02). There was equal self-perceived competency surrounding ATE knowledge between both men and women.ConclusionsFemale gastroenterology fellows in Canada lack mentorship and role models in ATE, which seems to be a primary deterrent from pursuing it as a career when compared to their male counterparts. Recognizing and addressing the lack of female leadership and visibility is necessary to improve parity and encourage women to train in the male-dominated field of ATE.

Project description:Fluorescence Imaging (FI) is a powerful technique in biological science and clinical medicine. Current FI devices that are used either for in-vivo or in-vitro studies are expensive, bulky and consume substantial power, confining the technique to laboratories and hospital examination rooms. Here we present a miniaturised wireless fluorescence endoscope capsule with low power consumption that will pave the way for future FI systems and applications. With enhanced sensitivity compared to existing technology we have demonstrated that the capsule can be successfully used to image tissue autofluorescence and targeted fluorescence via fluorophore labelling of tissues. The capsule incorporates a state-of-the-art complementary metal oxide semiconductor single photon avalanche detector imaging array, miniaturised optical isolation, wireless technology and low power design. When in use the capsule consumes only 30.9 mW, and deploys very low-level 468 nm illumination. The device has the potential to replace highly power-hungry intrusive optical fibre based endoscopes and to extend the range of clinical examination below the duodenum. To demonstrate the performance of our capsule, we imaged fluorescence phantoms incorporating principal tissue fluorophores (flavins) and absorbers (haemoglobin). We also demonstrated the utility of marker identification by imaging a 20 μM fluorescein isothiocyanate (FITC) labelling solution on mammalian tissue.
