Medical education in mainland China has undergone massive expansion and reforms in the past decades. A nation-wide survey of the five-year clinical medicine programs aimed to examine the course hours, pedagogies, learning resources and teaching staff of anatomy both at present and over the past three decades (1990-1999, 2000-2009, and 2010-2018). The directors or senior teachers from 90 out of the 130 five-year clinical medicine programs were invited to fill out a factual questionnaire by email. Ultimately, sixty-five completed questionnaires were received from 65 different schools. It was found that the total number of gross anatomy course hours has decreased by 11% in the past 30 years and that systematic and regional anatomy have been increasingly taught separately among the surveyed medical schools. Problem-based learning has been adopted in thirty-five (54%) of the surveyed schools, and team-based learning is used in ten (15%) of the surveyed schools. The surveyed schools reported receiving more donated cadavers in recent years, with the average number increasing from 20.67 ± 20.29 in 2000-2009 to 36.10 ± 47.26 in 2010-2018. However, this has not resulted in a decrease in the number of students who needed to share one cadaver (11.85 ± 5.03 in 1990-1999 to 14.22 ± 5.0 in 2010-2018). A decreasing trend regarding the teacher-student ratio (1:25.5 in 2000-2009 to 1:33.2 in 2010-2018) was also reported. The survey demonstrated the historical changes in gross anatomy education in China over the past thirty years.

For centuries cadaveric dissection has been a cornerstone of medical anatomy education. However, time and financial limitations in modern, compressed medical curricula, coupled with the abundance of alternate modalities, have raised questions about the role of dissection. This study was designed to explore student perceptions of the efficacy of a dissection program for learning musculoskeletal anatomy, and possible adaptations for appropriate inclusion of dissection in the modern medical curricula. A paper-based questionnaire was used to collect data from 174 medical students after completion of cadaveric dissections. Data were analyzed using both quantitative and qualitative methods. Students strongly believed that cadaver-based learning is essential to anatomy education and modern teaching modalities only complement this. Moreover, most students reported that dissection provided an additional, immersive learning experience that facilitated active learning and helped in developing manual competencies. Students with previous dissection experience or an interest in anatomy-related specialties were significantly more likely to attend dissection sessions. Students found that the procedural dissection components enhanced the knowledge of applied anatomy and is beneficial for the development of clinical skills. They welcomed the idea of implementing more procedure-based dissections alongside lectures and prosections-based practical (PBP) sessions. Cadaveric dissection plays an integral role in medical anatomy education. Time restraints and an increased focus on clinical significance, however, demand carefully considered adaptations of existing dissection protocols. The introduction of procedure-based dissection offers an innovative, highly engaging and clinically relevant package that would amalgamate skills essential to medical practice while retaining the benefits that have allowed dissection to stand the test of time.

Therapeutic endoscopic resection has gained favor for its ability to achieve high en bloc and histologically complete resection rates via a minimally invasive approach. The main technical difficulties faced by interventionists are first the lack of traction causing suboptimal visualization of the dissection field and second, the lack of triangulation using existing therapeutic apparatuses. These challenges can be overcome with the use of robots and the multiple degrees of freedom afforded by the robotic wrists. Nevertheless, complications such as bleeding and perforation can occur. It is hence beneficial for the robotic device to be equipped with additional abilities such as suturing. Once the robotic prototypes have been fully optimized and marketed, a structured program should be instituted to ensure proper and adequate training of the end-users. The future of robotics should then explore the possibility of developing a soft robot or a robot with more natural human-like movements. A robot with a force feedback mechanism would be superior and improve safety. Eventually, a supervised autonomous robot may perform interventions with greater precision and accuracy than an expert procedurist. This review describes the benefits of robot-assisted endoscopic resections, recent developments aimed at managing iatrogenic complications and future directions for robotic endoscopy.

Many Anglo-American universities have undertaken a paradigm shift in how the dissection of human material is approached, such that students are encouraged to learn about the lives of body donors, and to respectfully "personalize" them as human beings, rather than treating the specimens as anonymous cadavers. For the purposes of this study, this provision of limited personal information regarding the life of a body donor will be referred to as "personalization" of body donors. At this time, it is unknown whether this paradigm shift in the personalization of body donors can be translated into the German-speaking world. A shift from donor anonymity to donor personalization could strengthen students' perception of the donor as a "first patient," and thereby reinforce their ability to empathize with their future patients. Therefore, this study aimed to collect data about the current status of donation practices at German-speaking anatomy departments (n = 44) and to describe the opinions of anatomy departments, students (n = 366), and donors (n = 227) about possible donor personalization in medical education. Anatomy departments in Germany, Austria, and Switzerland were invited to participate in an online questionnaire. One-tenth of registered donors at Ulm University were randomly selected and received a questionnaire (20 items, yes-no questions) by mail. Students at the University of Ulm were also surveyed at the end of the dissection course (31 items, six-point Likert-scale). The majority of students were interested in receiving additional information about their donors (78.1%). A majority of donors also supported the anonymous disclosure of information about their medical history (92.5%). However, this information is only available in about 28% of the departments surveyed and is communicated to the students only irregularly. Overall, 78% of anatomy departments were not in favor of undertaking donor personalization. The results appear to reflect traditional attitudes among anatomy departments. However, since students clearly preferred receiving additional donor information, and most donors expressed a willingness to provide this information, one could argue that a change in attitudes is necessary. To do so, official recommendations for a limited, anonymous personalization of donated cadaveric specimens might be necessary. Anat Sci Educ 11: 282-293. © 2017 American Association of Anatomists.

"Modern" rectal cancer treatment began in the 18th century. However, initial results of the pioneer surgeons were very poor. During the next several decades, significant progress was made towards the cure of rectal cancer. Improvements have included lowering mortality, reducing recurrence, and optimizing functional outcomes. This article reviews the individuals and their advancements in rectal cancer treatment. It describes the changes in the surgical approach for tumor resection, the study of the lymphatic spread of rectal cancer and the advances in sphincter preservation procedures from the era of blunt dissection until the paradigm changing revolution of total mesorectal excision.

Throughout the modern history of anatomical dissection by medical and other health science students, cadavers have been anonymized. This has meant that students have been provided with limited, if any, information on the identities or medical histories of those they are dissecting. While there was little way around this when the bodies were unclaimed, this need not be the case when the bodies have been donated. However, with a few exceptions, no efforts have been made to change this model. Recent attempts to move anatomy teaching in a more humanistic direction, by emphasizing the cadaver as the students' first patient and with the growth of commemoration services following the dissecting process, raise the question of whether cadavers should continue to be anonymized. In laying a basis for discussion of this matter, we outline what appear to be the virtues of anonymity, and the form that alternatives to anonymity might take. The options identified are nonidentification, low information; nonidentification, moderate information; and identification, full information. The virtues and drawbacks of each of these possibilities are assessed by analyzing their value for students, and also for donors and their families. Policy issues raised by alternatives are also considered. This article provides a basis for continued discussion and suggestions for further research in this area.

Anatomical education has been undergoing reforms in line with the demands of medical profession. The aim of the present study is to assess the impact of a traditional method like cadaveric dissection in teaching/learning anatomy at present times when medical schools are inclining towards student-centered, integrated, clinical application models. The article undertakes a review of literature and analyzes the observations made therein reflecting on the relevance of cadaveric dissection in anatomical education of 21st century. Despite the advent of modern technology and evolved teaching methods, dissection continues to remain a cornerstone of anatomy curriculum. Medical professionals of all levels believe that dissection enables learning anatomy with relevant clinical correlates. Moreover dissection helps to build discipline independent skills which are essential requirements of modern health care setup. It has been supplemented by other teaching/learning methods due to limited availability of cadavers in some countries. However, in the developing world due to good access to cadavers, dissection based teaching is central to anatomy education till date. Its utility is also reflected in the perception of students who are of the opinion that dissection provides them with a foundation critical to development of clinical skills. Researchers have even suggested that time has come to reinstate dissection as the core method of teaching gross anatomy to ensure safe medical practice. Nevertheless, as dissection alone cannot provide uniform learning experience hence needs to be complemented with other innovative learning methods in the future education model of anatomy.

PURPOSE: The aim of this questionnaire survey was to assess the change in treatment modality over time and the current status of clinical outcomes of local treatment in Japanese patients with pathological T1 (pT1) rectal tumors. METHODS: A questionnaire survey was conducted by the 81st Congress of the Japan Society for Cancer of the Colon and Rectum. Clinical and pathological outcomes of all eligible patients undergoing local treatment were retrospectively collected from the medical records of each participating hospital. RESULTS: A total of 1371 pT1 patients from January 2006 to December 2008 (Period A), and 659 patients in 2013 (Period B) were registered. Approximately 70 % of patients underwent radical surgery in both periods. The rate of patients undergoing laparoscopic surgery increased from 46.5 % in Period A to 84.7 % in Period B. The indications for local excision were comparable with those for endoscopic intervention in 78 % of institutions. The rate of endoscopic submucosal dissection (ESD) increased from 20.1 % in Period A to 37.9 % in Period B, whereas local excision decreased from 36.9 to 24.1 %. Few patients received adjuvant therapy, and approximately 40 % of patients underwent additional surgery in both periods. Local recurrence was observed in 9.2 % of patients in Period A, with the median follow-up period being 59 months. Eighty-two percent of patients with local recurrence underwent salvage surgery. CONCLUSIONS: Local treatment with various modalities was properly performed for early rectal cancer. The number of less invasive modalities, such as laparoscopic surgery and ESD, increased between study periods.

Reduced contact hours and access to cadaveric/prosection-based teaching in medical education has led to many doctors reporting inadequate anatomical knowledge of junior doctors. This trend poses significant risk, but perhaps most of all in surgery. Here the opinions of surgeons regarding current and future teaching practices in anatomy were surveyed. Eighty surgeons were invited to complete a questionnaire, 48 of which were returned for a 60% response rate. Respondents were asked to select the method they viewed as the best method of teaching anatomy. Sixty-five percent of respondents selected "cadaver/prosection demonstration" (P < 0.001), while 55% of respondents, thought it should be enhanced in anatomy education (P < 0.001). Finally, respondents were asked to select what form of imaging should be further explored in anatomical education. Seventy-five percent of respondents' selected computerized tomography (CT) imaging compared to other imaging modalities (P < 0.001). These data show that surgeons view cadaveric/prosection-based teaching as the most beneficial method of teaching anatomy and that it should be enhanced in medical education. Furthermore, surgeons suggested that CT should be further integrated into anatomical education. These findings support the continued use of cadaveric/prosection-based teaching, and will help inform the integration of radiology in the design and implementation of anatomy teaching in medical education.

Even in the rapidly changing field of cadaver dissection, published guide books still play an important role in the anatomy lab. However, commercial manuals with lengthy volumes and inflexible copyrights have several limitations which can be complemented by open-source manuals. Recently, the authors have manufactured and distributed a free electronic dissection manual (anatomy.co.kr), where descriptions are written concisely and images are drawn schematically. Moreover, simplified signs are employed to represent the cadaver viewing angles and manner of dissection. Based on the original files of this manual, other anatomists can revise and utilize the descriptions and figures. We expect many updated versions of our manual to be shared between students all over the world.

OBJECTIVE: Work hour restrictions and current quality, financial, and legal concerns have reduced resident operative volume and autonomy. Although laboratory (cadaveric or animal) dissection has a rich history in neurosurgery, its current role in resident training is unclear. Recent literature suggests educators have looked to simulation to accelerate the learning curve of acquiring neurosurgical technical skills. The purpose of this study was to determine the prevalence, characteristics, and extent of laboratory dissection in neurosurgical residency programs in the United States. METHODS: A survey was sent to program directors of all 100 neurosurgical residency programs in the United States. RESULTS: Response rate was 65%. Most programs (93.8%) incorporate laboratory dissection into resident training. Most programs have 1-3 (36.1%) or 4-6 (39.3%) sessions annually. Residents in postgraduate years 2-6 (85.2%-93.4%) most commonly participate. The most common topics are cranial approaches (100%), spinal approaches (88.5%), spine instrumentation (80.3%), and endoscopy (50.8%). Thirty-one (47.7%) programs use artificial physical model or virtual reality simulators; the most common simulators are endoscopy (15.4%), microvascular anastomosis (13.8%), and endovascular (10.8%). Only 8 programs (13.1%) formally grade dissection skills. Educators (95.4%) believe laboratory dissection is an integral component of training and no respondent believed simulation could currently provide greater educational benefit than laboratory dissection. Most (89.2%) respondents would support a national "suggested" dissection curriculum and manual. CONCLUSIONS: In neurosurgical resident education, laboratory dissection is widely used; however, significant variation exists. Nonetheless, program directors believe laboratory dissection plays an integral role in neurosurgical training and is currently associated with greater educational benefit than simulation.

BACKGROUND: The purpose of this study was to assess the current usage, utilization and future direction of digital photography of gross surgical specimens in pathology laboratories across Canada. METHODS: An online survey consisting of 23 multiple choice and free-text questions regarding gross digital photography was sent out to via email to laboratory staff across Canada involved in gross dissection of surgical specimens. RESULTS: Sixty surveys were returned with representation from most of the provinces. Results showed that gross digital photography is utilized at most institutions (90.0%) and the primary users of the technology are Pathologists (88.0%), Pathologists' Assistants (54.0%) and Pathology residents (50.0%). Most respondents felt that there is a definite need for routine digital imaging of gross surgical specimens in their practice (80.0%). The top two applications for gross digital photography are for documentation of interesting/ complex cases (98.0%) and for teaching purposes (84.0%). The main limitations identified by the survey group are storage space (42.5%) and security issues (40.0%). Respondents indicated that future applications of gross digital photography mostly include teaching (96.6%), presentation at tumour boards/ clinical rounds (89.8%), medico-legal documentation (72.9%) and usage for consultation purposes (69.5%). CONCLUSIONS: The results of this survey indicate that pathology staff across Canada currently utilizes gross digital images for regular documentation and educational reasons. They also show that the technology will be needed for future applications in teaching, consultation and medico-legal purposes.

The technique of endoscopic submucosal dissection (ESD), which was developed for en bloc resection of large lesions in the stomach, has been widely accepted for the treatment of the entire gastrointestinal tract. Many minimally invasive endoscopic therapies based on ESD have been developed recently. Endoscopic submucosal excavation, submucosal tunneling endoscopic resection and laparoscopic-endoscopic cooperative surgery have been used to remove submucosal tumors, especially tumors which originate from the muscularis propria of the digestive tract. Peroral endoscopic myotomy has recently been described as a scarless and less invasive surgical myotomy option for the treatment of achalasia. Patients benefit from minimally invasive endoscopic therapy. This article, in the highlight topic series, provides detailed information on the indications and treatments for esophageal diseases.
