Abstract
Purpose Ultrasound examinations are often criticized for having higher examiner dependency compared to other imaging techniques. Compared to free-text reporting, structured reporting (SR) of head and neck sonography (HNS) achieves superior time efficiency as well as report quality. However, there are no findings concerning the influence of SR on the interrater reliability (IRR) of HNS. Materials and Methods Typical pathologies (n=4) in HNS were documented by video/images by two certified head and neck ultrasound instructors. Consequently, structured reports of these videos/images were created by n=9 senior physicians at departments of otolaryngology or maxillofacial surgery with DEGUM instructors on staff. Reports (n=36) were evaluated regarding overall completeness and IRR. Additionally, user satisfaction was assessed by a visual analog scale (VAS). Results SR yielded very high report completeness (91.8%) in all four cases with a substantial IRR (Fleiss' κ 0.73). Interrater agreement was high at 87.2% with very good user satisfaction (VAS 8.6). Conclusion SR has the potential to ensure high-quality examination reports with substantial comparability and very high user satisfaction. Furthermore, big data collection and analysis are facilitated by SR. Therefore, process quality, workflow, and scientific output are potentially enhanced by SR.

Abstract
AbstractBedside ultrasound has become one of the most important noninvasive and readily available diagnostic tools for critically ill patients. However, the current ultrasound training program for surgical residents is not standardized and is mostly unavailable to all surgical residents equally. Herein, we evaluated the effectiveness of the new training program in bedside ultrasound for surgical residents. Postgraduate residents (years 1 to 4) from the department of general surgery in a tertiary hospital attended the newly designed, 8-week ultrasound training course at the surgical intensive care unit. Didactic and experimental lectures about basic ultrasound physics and machine usage were delivered, followed by daily hands-on training to actual patients. Each participant documented their ultrasound findings and completed a self-assessment survey of ultrasound skills using the Likert scale. A total of 44 residents were enrolled, and only 36.4% of them were previously exposed to bedside ultrasound experience. Following the completion of the training course, the proficiency levels and the objective structured assessment of ultrasound skill scores showed significant improvement in every element (P < 0.001). The mean differences in pre- and post-course scores between post-graduate years and post hoc analysis revealed that the post-graduate year 2 group showed a higher improvement in most elements. Whether or not residents had previous experience with ultrasound, the significant improvement was seen in post-course scores. The knowledge and confidence of surgical residents in bedside ultrasound could be improved after our short training curriculum. Such education should be encouraged for all surgical residents to enhance their competency in performing bedside ultrasounds and use in managing critically ill patients.

Abstract
INTRODUCTION Point-of-care ultrasound (POCUS) is an increasingly used bedside tool. Applications in urology include the assessment of an undifferentiated acute scrotum, renal colic, and the guidance of suprapubic catheter placement. However, the user-dependent nature of this modality necessitates appropriate use and competence. The objective of this study was to develop and evaluate a low-cost, feasible, and guideline-based introductory POCUS program for Canadian urology residents. METHODS Residents from McMaster University's urology program completed a three-hour online course, followed by a three-hour hands-on seminar. Course material was developed by ultrasound educators based on national guidelines. Low-cost testicular phantoms and suprapubic catheter insertion models were constructed. Pre- and post-course surveys focused on participant skill confidence, while multiple-choice questionnaires assessed theoretical knowledge. RESULTS Fourteen residents participated in the course. Theoretical knowledge in POCUS improved significantly (p<0.001, d=2.2) and mean confidence scores improved for all skills, including performing kidney, bladder, and testicular POCUS (all p<0.001; d=3.4, 1.9, 2.9, respectively). Participants indicated that the course increased their confidence and likelihood of using POCUS in clinical practice, and that POCUS training should be integrated into urology training curricula. CONCLUSIONS This novel study included the development of an inexpensive, feasible, guideline-based introductory training program for urological POCUS, developed in collaboration with ultrasound educators. Participants significantly improved in theoretical knowledge and skill confidence. Although this study was limited to one residency program, the basis of this course may serve as a foundation for the development of competency-based training for urological POCUS in Canada.

Abstract
BACKGROUND Ultrasound is an established imaging modality in general surgery. With the increasing use of bedside point-of-care ultrasounds, general surgeons have been incorporating this skill into their clinical practice. This systematic review provides an up-to-date summary of the evidence for abdominal ultrasound scans performed by general surgeons to diagnose intra-abdominal pathology. METHODS Two independent reviewers searched the PubMed database between 1 January 1980 and 1 June 2020. Articles about surgeon-performed abdominal ultrasound in adult patients were included. Studies on trauma and vascular surgery were excluded. RESULTS 26 articles met the inclusion criteria, presented as a narrative analysis. There was good evidence for the use of surgeon-performed ultrasound, particularly in gallstone-related diseases and moderate evidence for the use of ultrasound in appendicitis. Further evidence is required for point-of-care ultrasounds for other pathologies such as diverticulitis and groin hernias. Ultrasound training for general surgeons is variable with notable heterogeneity across studies. CONCLUSION A standardised training programme for general surgeons will greatly improve confidence and skill. There is good evidence for the use of bedside ultrasound by general surgeons in the acute and elective setting with reduced time to definitive treatment and fewer unnecessary hospital admissions.

Abstract
La ecografía es un estudio de imágenes diagnósticas con una amplia historia de uso en todas las especialidades de la Medicina; su advenimiento ha ayudado al enfoque diagnóstico e, incluso, al abordaje terapéutico de los pacientes.
Desde su origen en el siglo XIX con mediciones de la velocidad del sonido en el agua, hasta el desarrollo de las máquinas de ultrasonografía sustentadas en los avances de la tecnología, la física y la ingeniería, se ha utilizado de manera notable en la Medicina.
No hay duda de que, en el campo de la Cirugía General, ha sido útil para el manejo de los pacientes con enfermedad abdominal. La tecnología ecográfica permite identificar las características de un órgano normal y, cuando este patrón se afecta, orienta sobre la causa o determina la enfermedad que puede estar produciendo la alteración.
En la presente revisión, se hace un recuento histórico del nacimiento de la ecografía, su aplicación en el campo de la medicina y su utilidad para el cirujano general en diversas circunstancias de la práctica quirúrgica.

Abstract
BACKGROUND Acute cholecystitis (AC), frequently responsible for presentation to the emergency department, requires expedient diagnosis and definitive treatment by a general surgeon. Ultrasonography, usually performed by radiology technicians and reported by radiologists, is the first-line imaging study for the assessment of AC. Targeted point-of-care ultrasound (POCUS), particularly in the hands of the treating surgeon, may represent an evolution in surgical decision-making and may expedite care, reducing morbidity and cost. METHODS This consensus guideline was written under the auspices of the European Society of Trauma and Emergency Surgery (ESTES) by the POCUS working group. A systematic literature search identified relevant papers on the diagnosis and treatment of AC. Literature was critically-appraised according to the GRADE evidence-based guideline development method. Following a consensus conference at the European Congress of Trauma & Emergency Surgery (Valencia, Spain, May 2018), final recommendations were approved by the working group, using a modified e-Delphi process, and taking into account the level of evidence of the conclusion. RECOMMENDATIONS We strongly recommend the use of ultrasound as the first-line imaging investigation for the diagnosis of AC; specifically, we recommend that POCUS may be adopted as the primary imaging adjunct to surgeon-performed assessment of the patient with suspected AC. In line with the Tokyo guidelines, we strongly recommend Murphy's sign, in conjunction with the presence of gallstones and/or wall thickening as diagnostic of AC in the correct clinical context. We conditionally recommend US as a preoperative predictor of difficulty of cholecystectomy. There is insufficient evidence to recommend contrast-enhanced ultrasound or Doppler ultrasonography in the diagnosis of AC. We conditionally recommend the use of ultrasound to guide percutaneous cholecystostomy placement by appropriately-trained practitioners. CONCLUSIONS Surgeons have recently embraced POCUS to expedite diagnosis of AC and provide rapid decision-making and early treatment, streamlining the patient pathway and thereby reducing costs and morbidity.

Abstract
ABSTRACTObjectivesPerforming an extended Focused Assessment with Sonography in Trauma (eFAST) exam is common practice in the initial assessment of trauma patients. The objective of this study was to systematically review the published literature on diagnostic accuracy of all components of the eFAST exam.MethodsWe searched Medline and Embase from inception through October 2018, for diagnostic studies examining the sensitivity and specificity of the eFAST exam. After removal of duplicates, 767 records remained for screening, of which 119 underwent full text review. Meta-DiSc™ software was used to create pooled sensitivities and specificities for included studies. Study quality was assessed using the Quality in Prognostic Studies (QUADAS-2) tool.ResultsSeventy-five studies representing 24,350 patients satisfied our selection criteria. Studies were published between 1989 and 2017. Pooled sensitivities and specificities were calculated for the detection of pneumothorax (69% and 99% respectively), pericardial effusion (91% and 94% respectively), and intra-abdominal free fluid (74% and 98% respectively). Sub-group analysis was completed for detection of intra-abdominal free fluid in hypotensive (sensitivity 74% and specificity 95%), adult normotensive (sensitivity 76% and specificity 98%) and pediatric patients (sensitivity 71% and specificity 95%).ConclusionsOur systematic review and meta-analysis suggests that e-FAST is a useful bedside tool for ruling in pneumothorax, pericardial effusion, and intra-abdominal free fluid in the trauma setting. Its usefulness as a rule-out tool is not supported by these results.

Abstract
INTRODUCTION Femoral hernia is a rare and often misdiagnosed condition in childhood. The aim of our study was to demonstrate that the laparoscopic approach improves diagnostic accuracy and offers a safe and effective treatment. METHODS A retrospective study of 687 pediatric patients who underwent laparoscopic inguinal hernia repair from January 2000 to December 2015 was performed. RESULTS Femoral hernias were identified in 16 patients (2.3%). The right side was affected in 10 cases (62.5%), the left side in 5 (31.2%), and 1 case was bilateral (6.2%). The mean age of patients was 8.00 ± 3.81 years, and there was a male predominance. Preoperative diagnosis was femoral hernia in eight cases (50%) and indirect inguinal hernia in the remaining eight (50%). Seven children (43.8%) presented with hernia recurrence after having undergone an open ipsilateral indirect hernia repair. A modified laparoscopic McVay technique was performed in 12 cases (70.6%). An epigastric artery injury by trocar occurred in one patient. All operations were completed laparoscopically. The mean surgical time was 45.6 ± 22.9 min for unilateral cases and 110 ± 10.0 min for bilateral cases. No immediate postoperative complications were noted. The mean postoperative hospital stay was 0.6 ± 0.4 days. No recurrence was observed after a median follow-up of 11 years (range, 4-16 years). CONCLUSION Femoral hernia is a rare pathology in pediatric patients that is often difficult to diagnose. The laparoscopic approach is effective in the diagnosing and treating these hernias, and it allows for the simultaneous repair of multiple groin defects.

Abstract
BACKGROUND Intensivist-performed ultrasound (IPUS) is an adjunctive tool used to assist in resuscitation and management of critically ill patients. It allows clinicians real-time information through noninvasive methods. We aimed to evaluate the types of IPUS performed and the methods surgical critical care (SCC) fellows are trained along with challenges in training. METHODS One hundred SCC fellowship directors were successfully sent an email inviting them to participate in a short Web-based survey. We inquired about program characteristics including hospital type, fellowship size, faculty size and training, dedicated surgical critical care beds, and ultrasound equipment availability. The survey contained questions regarding the program directors' perception on importance on cost effectiveness of IPUS, types of IPUS examinations performed, fellows experience with IPUS, challenges to training, and presence and methods of quality assurance (QA) programs. RESULTS A total of 38 (38.0%) program directors completed the survey. Using a 100-point Likert scale, the majority of the respondents indicated that IPUS is important to patient care in the SICU and is cost-effective (mean score 85.5 and 84.6, respectively). Most (34, 89.5%) utilize IPUS and conduct a mean of 5.1 different examination types with FAST being the most prevalent examination (33, 86.8%). Thirty-three (86.8%) programs include IPUS in their SCC training with varying amounts of time spent training. Of these programs, 19 (57.6%) have a specific curriculum. The most frequently used modalities for training fellows were informal bedside teaching (28, 84.8%), hands-on lectures (20, 60.6%) and formal lectures (19, 57.6%). The top three challenges program directors cited for IPUS education was time (23, 69.7%), followed by concerns for ongoing QA (19, 57.6%) and lack of faculty trained in IPUS (18, 53.9%). Only 20 (60.6%) programs review images as a part of QA/quality improvement. CONCLUSIONS Utilization and training of IPUS is common in SCC fellowships. There is varied education type and training time devoted to IPUS which could lead to gaps in knowledge and care. Development of a standard curriculum for SCC fellowships could assist surgical intensivists in achieving a base of knowledge in IPUS to create a more homogenously trained workforce and standards of care.

Abstract
Point-of-care ultrasound is an ultrasound examination that is made at the bedside by the examining clinician in the Accident and Emergency department, clinic, ward, or operating theatre, and it has been growing in popularity since it was first introduced in the 1990s. It is used as an adjunct to clinical examination to aid diagnosis or treatment. We have carried out a pilot survey to assess whether oral and maxillofacial surgeons in the United Kingdom either need or desire to make such an examination. We present the results of our survey and discuss the uses and benefits of point-of-care ultrasound in oral and maxillofacial surgery.

Abstract
Advances in technology and increased affordability of machines have allowed ultrasound to become ubiquitous across the spectrum of medical care. Increasing portability has brought ultrasound to the point of care in multiple medical specialties. Formal ultrasound training is rapidly being incorporated into multispecialty residency programs and undergraduate medical education curricula, yet little formal training exists for physician assistants (PAs) on this emerging clinical adjunct. This article outlines recommendations for and barriers to the incorporation of bedside ultrasound into PA clinical practice.

Abstract
BACKGROUND Despite the development of ultrasound courses by the American College of Surgeons two decades ago, many residencies lack formal ultrasound training. The aim of this study was to assess the previous ultrasound experience of residents and the efficacy of a new ultrasound curriculum by comparing pre- and post-course tests. METHODS A pre-course survey and test were sent to all residents at the University of Texas Southwestern Medical Center. Pre-interns and junior residents received a didactic lecture on ultrasound basics and the extended focused assessment with sonography for trauma and were given hands-on practice. Finally, a post-course test and survey were sent to the pre-interns and junior residents. RESULTS Only 11.3% of the residents reported having previous exposure to a formal ultrasound curriculum, and only 12.7% were taught by faculty. On the pre-course test, there was no difference in performance among senior residents, junior residents, and pre-interns (P = 0.114). After taking the course, the pre-interns improved their performance, and their average increased from 44.3% (standard deviation = 12.4%) to 66.1% (standard deviation = 12.2%; P < 0.001). The junior residents also had an improvement in their performance on the test after the course (P < 0.001). Junior residents performed better than pre-interns on the post-course test (P = 0.001). CONCLUSIONS The knowledge of surgical residents in ultrasound basics and extended focused assessment with sonography for trauma can be improved with the establishment of an ultrasound curriculum. We believe that such an educational endeavor should be encouraged by all surgical residencies.

Abstract
OBJECTIVES Despite the rise of ultrasound in medical education (USMED), multiple barriers impede the implementation of such curricula in medical schools. No studies to date have surveyed individuals who are successfully championing USMED programs. This study aimed to investigate the experiences with ultrasound integration as perceived by active USMED directors across the United States. METHODS In 2014, all allopathic and osteopathic medical schools in the United States were contacted regarding their status with ultrasound education. For schools with required point-of-care ultrasound curricula, we identified the USMED directors in charge of the ultrasound programs and sent them a 27-question survey. The survey included background information about the directors, ultrasound program details, the barriers directors faced toward implementation, and the directors' attitudes toward ultrasound education. RESULTS One-hundred seventy-three medical schools were contacted, and 48 (27.7%) reported having a formal USMED curriculum. Thirty-six USMED directors responded to the survey. The average number of years of USMED curriculum integration was 2.8 years (SD, 2.9). Mandatory ultrasound curricula had most commonly been implemented into years 1 and 2 of medical school (71.4% and 62.9%, respectively). The most common barriers faced by these directors when implementing their ultrasound programs were the lack of funding for faculty/ equipment (52.9%) and lack of time in current medical curricula (50.0%). CONCLUSIONS Financial commitments and the full schedules of medical schools are the current prevailing roadblocks to implementation of ultrasound education. Experiences drawn from current USMED directors in this study may be used to help programs starting their own curricula.

Abstract
Since the first medical student ultrasound electives became available more than a decade ago, ultrasound in undergraduate medical education has gained increasing popularity. More than a dozen medical schools have fully integrated ultrasound education in their curricula, with several dozen more institutions planning to follow suit. Starting in June 2012, a working group of emergency ultrasound faculty at the California medical schools began to meet to discuss barriers as well as innovative approaches to implementing ultrasound education in undergraduate medical education. It became clear that an ongoing collaborative could be formed to discuss barriers, exchange ideas, and lend support for this initiative. The group, termed Ultrasound in Medical Education, California (UMeCali), was formed with 2 main goals: to exchange ideas and resources in facilitating ultrasound education and to develop a white paper to discuss our experiences. Five common themes integral to successful ultrasound education in undergraduate medical education are discussed in this article: (1) initiating an ultrasound education program; (2) the role of medical student involvement; (3) integration of ultrasound in the preclinical years; (4) developing longitudinal ultrasound education; and (5) addressing competency.

Abstract
Gastric cancer is occasionally diagnosed using transabdominal ultrasonography (US) during screening or investigation of patients with abdominal symptoms. Therefore, the present study analyzed the association of the tumor diameter, pathological T (pT) staging and depth of invasion with the detection of gastric cancer using US. Patient records were analyzed retrospectively and 13 patients were enrolled, who underwent US screening prior to endoscopic mucosal resection, endoscopic submucosal dissection or surgery. In total, 5 patients were diagnosed with gastric cancer using US (positive detection group), while US was unable to detect the gastric cancer in 8 patients (negative detection group). The tumor diameter and depth of invasion were determined by pathologists. One-way analysis of variance or the χ2 test was performed. Wall thickness in gastric cancer cases ranged between 7 and 20 mm (mean, 12.2±5.9 mm), as measured using abdominal US. The hemoglobin level was significantly lower in the positive detection patients compared with the negative detection patients (P=0.0455). In addition, the diameters of the gastric wall in the negative and positive detection patients were 24.5±16.4 and 54.4±26.2 mm, respectively (P=0.0266). These results indicate that gastric cancer in the positive detection patients were at a more advanced-stage compared with that in the negative detection patients. Furthermore, gastric cancer with a stage over pT2 was diagnosed using abdominal US (P=0.0242), whereas stage pT1a gastric cancer was not detected by abdominal US. Gastric tumors invading deeper than the submucosa were diagnosed using US (P=0.0242). However, the gastric cancer cases limited to the mucosa remained undetected. In conclusion, the detection of gastric cancer correlated well with the tumor diameter, pT staging and depth of invasion.

Abstract
Hashimoto thyroiditis (HT), now considered the most common autoimmune disease, was described over a century ago as a pronounced lymphoid goiter affecting predominantly women. In addition to this classic form, several other clinico-pathologic entities are now included under the term HT: fibrous variant, IgG4-related variant, juvenile form, Hashitoxicosis, and painless thyroiditis (sporadic or post-partum). All forms are characterized pathologically by the infiltration of hematopoietic mononuclear cells, mainly lymphocytes, in the interstitium among the thyroid follicles, although specific features can be recognized in each variant. Thyroid cells undergo atrophy or transform into a bolder type of follicular cell rich in mitochondria called Hürthle cell. Most HT forms ultimately evolve into hypothyroidism, although at presentation patients can be euthyroid or even hyperthyroid. The diagnosis of HT relies on the demonstration of circulating antibodies to thyroid antigens (mainly thyroperoxidase and thyroglobulin) and reduced echogenicity on thyroid sonogram in a patient with proper clinical features. The treatment remains symptomatic and based on the administration of synthetic thyroid hormones to correct the hypothyroidism as needed. Surgery is performed when the goiter is large enough to cause significant compression of the surrounding cervical structures, or when some areas of the thyroid gland mimic the features of a nodule whose cytology cannot be ascertained as benign. HT remains a complex and ever expanding disease of unknown pathogenesis that awaits prevention or novel forms of treatment.
