ABSTRACT
Introducción y objetivo: Analizar el logro de los objetivos docentes desarrollados durante el escenario de los casos de simulación a través de la valoración del profesor, los participantes observadores y quien realiza la propia simulación. Sujetos y métodos: Estudio observacional, prospectivo, descriptivo y unicéntrico, realizado con estudiantes de tercer curso de Medicina de la Universitat Autònoma de Barcelona. Se evalúan los objetivos docentes para cada caso clínico simulado por parte de los estudiantes que realizan la simulación, los observadores y el profesor. La evaluación numérica sigue una escala de tipo escala visual analógica y la categórica los clasifica en conseguidos, parcialmente conseguidos y no conseguidos. El estado nervioso y la comodidad de los alumnos también se evalúan numéricamente. Resultados: Se ha registrado la valoración de los objetivos de 929 participantes. La evaluación de los objetivos tiene un valor medio superior a 7 para cada uno de ellos. Existe una diferencia de 1,5-2 puntos en la valoración media entre el primer caso y el último, y no hay ningún alumno que no consiga los objetivos en el último caso. Se describe un estado de nervios alrededor de 4,5 y de comodidad alrededor de 7, sin diferencias entre los distintos evaluadores. Conclusiones: El logro de los objetivos se consigue de forma notable. Entre el primer caso y el último existe una significativa diferencia en el grado de obtención de los objetivos. No hay una relación entre el estado emocional de los participantes y la consecución de los objetivos.(AU)
Introduction and aim: To analyze the achievement of the educational objectives developed during the scenario of the simulation cases through the assessment of the teacher, the observer participants and the person who performs the simulation itself. Subjects and methods: Observational, prospective, descriptive and single-center study, carried out with 3rd year Medicine students at the Universitat Autònoma de Barcelona. The teaching objectives for each simulated clinical case are evaluated by the students who carry out the simulation, the observers and the teacher. The numerical evaluation follows a VAS-type scale and the categorical one classifies them as achieved, partially achieved and not achieved. The nervous state and comfort of the students are also evaluated numerically. Results: The evaluation of the objectives of 929 participants has been registered. The evaluation of the objectives has an average value greater than 7 for each one of them. There is a difference of 1.5-2 points in the average assessment between the first case and the last, with no student not achieving the objectives in the last case. A state of nerves around 4.5 and comfort around 7 is described, with no differences between the different evaluators. Conclusions: The achievement of the objectives is achieved in a remarkable way. Between the first case and the last, there is a significant difference in the degree of achievement of the objectives. There is no relationship between the emotional state of the participants and the achievement of the objectives.(AU)

PURPOSE: Persistent occult hypoperfusion after initial resuscitation is strongly associated with increased morbidity and mortality after severe trauma. The objective of this study was to analyze regional tissue oxygenation, along with other global markers, as potential detectors of occult shock in otherwise hemodynamically stable trauma patients. METHODS: Trauma patients undergoing active resuscitation were evaluated 8 h after hospital admission with the measurement of several global and local hemodynamic/metabolic parameters. Apparently hemodynamically stable (AHD) patients, defined as having SBP ≥ 90 mmHg, HR < 100 bpm and no vasopressor support, were followed for 48 h, and finally classified according to the need for further treatment for persistent bleeding (defined as requiring additional red blood cell transfusion), initiation of vasopressors and/or bleeding control with surgery and/or angioembolization. Patients were labeled as "Occult shock" (OS) if they required any intervention or "Truly hemodynamically stable" (THD) if they did not. Regional tissue oxygenation (rSO2) was measured non-invasively by near-infrared spectroscopy (NIRS) on the forearm. A vascular occlusion test was performed, allowing a 3-min deoxygenation period and a reoxygenation period following occlusion release. Minimal rSO2 (rSO2min), Delta-down (rSO2-rSO2min), maximal rSO2 following cuff-release (rSO2max), and Delta-up (rSO2max-rSO2min) were computed. The NIRS response to the occlusion test was also measured in a control group of healthy volunteers. RESULTS: Sixty-six consecutive trauma patients were included. After 8 h, 17 patients were classified as AHD, of whom five were finally considered to have OS and 12 THD. No hemodynamic, metabolic or coagulopathic differences were observed between the two groups, while NIRS-derived parameters showed statistically significant differences in Delta-down, rSO2min, and Delta-up. CONCLUSIONS: After 8 h of care, NIRS evaluation with an occlusion test is helpful for identifying occult shock in apparently hemodynamically stable patients. LEVEL OF EVIDENCE: IV, descriptive observational study. TRIAL REGISTRATION: ClinicalTrials.gov Registration Number: NCT02772653.

INTRODUCTION: The doctorate is the third cycle of official university studies, which, through the defense of the doctoral thesis leads to the acquisition of the title of doctor or PhD from the Anglo-Saxon countries. Royal Decree law 99/2011 regulates doctoral programs, with a wide margin on quality requirements. The objective of this study is to find out if there is this variation in the requirements of the doctorate programs of the different departments of surgery of the Spanish public universities and to establish a quality scale. METHODS: Cross-sectional observational study from 2/22/2021 to 3/3/2021, through a survey sent electronically to the professors of the departments of surgery. RESULTS: Thirty-five departments of surgery were consulted, obtaining a response in 29 of them (82.9%). The observed variation regarding requirements has been basically in the quality of the research project, in fact in 25 (86.2%) there are no regulations on this. When it is presented in the form of a compendium of articles, these are required to be original in 15 (51.7%). Regarding the position as author, the doctoral student must be the preferred author, at least in 2 articles in 14 (48.4%) of the programs. In 14 departments (48.4%) there are no regulations on the position of the articles and quartiles of journals. When scoring the different programs according to their requirements, the variability is high, ranging between 2 and 19 points. Funding for the development of the doctorate is meager. CONCLUSIONS: There is a wide variability in the requirement of doctoral programs. Homogeneous levels of demand must be defined to promote and protect higher-level doctorates.

AIM: The aim was to describe the robot-assisted intracorporeal anastomosis technique in left colon surgery (rLCS) and report the initial results. METHOD: The rLCS was performed in 25 consecutive patients, starting with a Pfannenstiel incision and introducing a prepared anvil. The robot was docked and the affected segment resected. Colotomy was performed and the anvil was introduced in the proximal segment. End-to-end anastomosis was performed and reinforced. An air-leak test was performed. RESULTS: The results varied in terms of patient's age, American Society of Anesthesiologists grade, weight and the technique performed. Most patients had cancer. There was no suture failure or mortality, and the mean hospital stay was 3 days. CONCLUSIONS: The rLCS is a safe, reproducible technique with good initial results. Prospective studies should be performed to demonstrate its advantages.

PURPOSE: Combined endoscopic and laparoscopic surgery (CELS) has emerged as a promising method for managing complex benign lesions that would otherwise require major colonic resection. The aim of this study was to describe the different techniques and to evaluate the safety of CELS, assess its outcomes in a technique that is scarcely widespread in our environment. METHOD: Observational retrospective study, short-term outcomes of patients undergoing CELS for benign colon polyps from October 2018 to June 2020 were evaluated. Postoperative outcomes, length of hospital stay and pathological findings were evaluated. RESULTS: Seventeen consecutive patients underwent CELS during the study period. The median size of the lesion was 3.5 cm (range 2.5-6.5 cm), the most frequent location was the cecum (10 from 17). Most patients treated with CELS underwent an endoscopic-assisted laparoscopic wedge resection (11 from 17). In four patients this resection was combined with another CELS technique, and two patients underwent an endoscopic-assisted laparoscopic segment resection. The success rate of CELS in our series was in 14 from 17 (82.4%). The median operative time was 85 min (range 50-225 min). The median hospital stay was 2 days (range 1-15 days). One patient experienced an organ/space surgical site infection which did not require further intervention. Four lesions were shown to be malignant by postoperative pathology study. CONCLUSION: CELS is a safe and multidisciplinar technique that requires collaboration between gastroenterologists and surgeons. It can be considered as an alternative to colonic resection for complex benign colonic polyps.

BACKGROUND: Despite advances in trauma management, half of trauma deaths occur secondary to bleeding. Currently, hemostatic resuscitation strategies consist of empirical transfusion of blood products in a predefined fixed ratio (1:1:1) to both treat hemorrhagic shock and correct trauma-induced coagulopathy. At our hospital, the implementation of a resuscitation protocol guided by viscoelastic hemostatic assays (VHAs) with rotational thromboelastometry has resulted in a goal-directed approach. The objective of the study is twofold, first to analyze changes in transfusion practices overtime and second to identify the impact of these changes on coagulation parameters and clinical outcomes. We hypothesized that progressive VHA implementation results in a higher administration of fibrinogen concentrate (FC) and lower use of blood products transfusion, especially plasma. METHODS: A total of 135 severe trauma patients (January 2008 to July 2019), all requiring and initial assessment for high risk of trauma-induced coagulopathy based on high-energy injury mechanism, severity of bleeding and hemodynamic instability were included. After 2011 when we first modified the transfusion protocol, a progressive change in transfusional management occurred over time. Three treatment groups were established, reflecting different stages in the evolution of our strategy: plasma (P, n = 28), plasma and FC (PF, n = 64) and only FC (F, n = 42). RESULTS: There were no significant differences in baseline characteristics among groups. Progressive implementation of rotational thromboelastometry resulted in increased use of FC over time ( p < 0.001). Regression analysis showed that group F had a significant reduction in transfusion of packed red blood cells ( p = 0.005), plasma ( p < 0.001), and platelets ( p = 0.011). Regarding outcomes, F patients had less pneumonia ( p = 0.019) and multiorgan failure ( p < 0.001), without significant differences for other outcomes. Likewise, overall mortality was not significantly different. However, further analysis comparing specific mortality due only to massive hemorrhage in the F group versus all patients receiving plasma, it was significantly lower ( p = 0.037). CONCLUSION: Implementing a VHA-based algorithm resulted in a plasma-free strategy with higher use of FC and a significant reduction of packed red blood cells transfused. In addition, we observed an improvement in outcomes without an increase in thrombotic complications. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

BACKGROUND: Endorectal ultrasound and rectal magnetic resonance are sometimes unable to differentiate between stages T2 and T3 in rectal adenomas that are possible adenocarcinomas, or between stages T1 and T2 in rectal adenocarcinomas. These cases of diagnostic uncertainty raise a therapeutic dilemma: transanal endoscopic surgery (TES) or total mesorectal excision (TME)? METHODS: An observational study of a cohort of 803 patients who underwent TES from 2004 to 2021. Patients operated on for adenoma (group I) and low-grade T1 adenocarcinoma (group II) were included. The variables related to uncertain diagnosis, and to the definitive pathological diagnosis of adenocarcinoma stage higher than T1, were analyzed. RESULTS: A total of 638 patients were included. Group I comprised 529 patients, 113 (21.4%) with uncertain diagnosis. Seventeen (15%) eventually had a pathological diagnosis of adenocarcinoma higher than T1. However, the variable diagnostic uncertainty was a risk factor for adenocarcinoma above T1 (OR 2.3, 95% CI 1.1-4.7). Group II included 109 patients, eight with uncertain diagnosis (7.3%). Two patients presented a definitive pathological diagnosis of adenocarcinoma above T1. CONCLUSIONS: On the strength of these data, we recommend TES as the initial indication in cases of diagnostic uncertainty. Multicenter studies with larger samples for both groups should now be performed to further assess this strategy of initiating treatment with TES.
ABSTRACT
PURPOSE: The intrarectal suture is considered a high technically complex procedure. The study's objectives were to assess the feasibility of making an intrarectal knot, through an in vitro study and assessing whether the video tutorial facilitates learning. MATERIALS AND METHODS: A detailed description of the technique. A comparative observational cross-sectional study in surgeons with no previous experience in intrarectal knots. RESULTS: Twenty-one of these 32 participants passed the intrarectal knot test without video tutorial (T1) (65.6%), and 26 (81.2%) after the video tutorial (T2) (P=0.26). The mean time taken to tie the knot fell from 74 seconds (SD=46) in T1 to 41 seconds (SD=41) in T2 (P<0.001). At T1, 26 participants (81.3%) described the technique as difficult, but only 7 (21.9%) at T2 (P<0.001). CONCLUSIONS: Performing the intrarectal knot suture is feasible. Despite the technical difficulty, the video tutorial is sufficient for surgeons to learn the technique.

Introducción: La exactitud del FAST disminuye notablemente en los pacientes politraumáticos con fractura pélvica. El objetivo es analizar las consecuencias de tomar decisiones terapéuticas basadas en el resultado del FAST en los pacientes politraumáticos con fractura de pelvis. Métodos: Estudio descriptivo de pacientes con politraumatismos mayores de 16 años que han ingresado en el área de críticos o que han fallecido previamente, con fractura pélvica. El resultado del FAST ha sido comparado con un valor realmente positivo o negativo según el resultado de la laparotomía o de la tomografía computarizada.Resultados: En 13 años, se ha incluido a 263 pacientes politraumáticos con fractura pélvica (ISS medio de 31; mortalidad 19%). El FAST tenía una sensibilidad del 65,2%, una especificidad del 69%, una tasa de falsos negativos del 34,8% y una tasa de falsos positivos del 30,9%. Los pacientes hemodinámicamente inestables tenían el doble de mortalidad que los pacientes estables (27% vs. 14%, p <0,05). Los pacientes con un FAST positivo tenían mayor mortalidad que los pacientes con FAST negativo (43% vs. 26%); 4 de 10 pacientes hemodinámicamente inestables con un FAST falsamente positivo que se sometieron a laparotomía exploradora innecesaria murieron por shock hipovolémico. La mortalidad se redujo del 60 al 20% asociando un packing preperitoneal. Conclusiones: La reducida eficacia del FAST en pacientes con fractura de pelvis nos obliga a cuestionarnos las consecuencias de la toma de decisiones terapéuticas con base en sus resultados. Los pacientes con FAST falsamente positivo tienen una mortalidad mayor, que se puede reducir aplicando un packing preperitoneal. (AU)
Introduction: FAST is essential to decide if trauma patients need laparotomy, but has a notably decrease in accuracy in patients with pelvic fracture. Our objective is to analyze the consequences of therapeutic decision-making based on the FAST results in trauma patients with pelvic fracture. Methods: Descriptive study that includes trauma patients older than 16 with a pelvic fracture admitted to the critical care area or who were fallecimiento. FAST result was compared with a true positive or negative value according to the results of laparotomy or abdominal CT. We recorded diagnosis and treatment of each injury and resolution of the case, detailing the cause of death, among all variables. Results: Over the 13year period, we included 263 trauma patients with pelvic fracture, with a mean ISS of 31 and mortality of 19%. FAST had a sensitivity of 65.2%, specificity of 69%, false negative rate of 34.8% and false positive rate of 30.9%. Hemodynamically unstable patients died twice as many stable patients (27% vs. 14%, p <0.05). Patients with positive FAST died more than negative FAST (43% vs. 26%); and 4 of 10 hemodynamically unstable patients who underwent non therapeutic laparotomy after presenting a false positive FAST died from hypovolemic shock. The mortality rate fell from 60% to 20% when preperitoneal packing was performed before angio-embolization of the pelvis. Conclusion: FAST has low accuracy in polytraumatized patients with pelvic fracture. Patients with false positive FAST have higher mortality, which can be reduce notably applying a preperitoneal packing. (AU)

OBJECTIVE: Mild AD can be treated safely and effectively on an outpatient basis without antibiotics. SUMMARY OF BACKGROUND DATA: In recent years, it has shown no benefit of antibiotics in the treatment of uncomplicated AD in hospitalized patients. Also, outpatient treatment of uncomplicated AD has been shown to be safe and effective. METHODS: A Prospective, multicentre, open-label, noninferiority, randomized controlled trial, in 15 hospitals of patients consulting the emergency department with symptoms compatible with AD.The Participants were patients with mild AD diagnosed by Computed Tomography meeting the inclusion criteria were randomly assigned to control arm (ATB-Group): classical treatment (875/125âmg/8âh amoxicillin/clavulanic acid apart from anti-inflammatory and symptomatic treatment) or experimental arm (Non-ATB-Group): experimental treatment (antiinflammatory and symptomatic treatment). Clinical controls were performed at 2, 7, 30, and 90âdays.The primary endpoint was hospital admission. Secondary endpoints included number of emergency department revisits, pain control and emergency surgery in the different arms. RESULTS: Four hundred and eighty patients meeting the inclusion criteria were randomly assigned to Non-ATB-Group (n = 242) or ATB-Group (n = 238). Hospitalization rates were: ATB-Group 14/238 (5.8%) and Non-ATB-Group 8/242 (3.3%) [mean difference 2.58%, 95% confidence interval (CI) 6.32 to -1.17], confirming noninferiority margin. Revisits: ATB-Group 16/238 (6.7%) and Non-ATB-Group 17/242 (7%) (mean difference -0.3, 95% CI 4.22 to -4.83). Poor pain control at 2âdays follow up: ATB-Group 13/230 (5.7%), Non-ATB-Group 5/221 (2.3%) (mean difference 3.39, 95% CI 6.96 to -0.18). CONCLUSIONS: Nonantibiotic outpatient treatment of mild AD is safe and effective and is not inferior to current standard treatment.

AIM: The COVID-19 pandemic has forced surgeons to adapt their standard procedures. The modifications introduced are designed to favour minimally invasive surgery. The positive results obtained with intracorporeal resection and anastomosis in the right colon and rectum prompt us to adapt these procedures to the left colon. We describe a 'don't touch the bowel' technique and outline the benefits to patients of the use of less surgically aggressive techniques and also to surgeons in terms of the lower emission of aerosols that might transmit the COVID-19 infection. METHODS: This was an observational study of intracorporeal resection and anastomosis in left colectomy. We describe the technical details of intracorporeal resection, end-to-end stapled anastomosis and extraction of the specimen through mini-laparotomy in the ideal location. RESULTS: We present preliminary results of 17 patients with left-sided colonic pathologies, 15 neoplasia and two diverticular disease, who underwent four left hemicolectomies, six sigmoidectomies and seven high anterior resections. Median operating time was 186 min (range 120-280). No patient required conversion to extracorporeal laparoscopy or open surgery. Median hospital stay was 4.7 days (range 3-12 days). There was one case of anastomotic leak managed with conservative treatment. CONCLUSION: Intracorporeal resection and end-to-end anastomosis with the possibility of extraction of the specimen by a mini-laparotomy in the ideal location may present benefits and also adapts well to the conditions imposed by the COVID-19 pandemic. Future comparative studies are needed to demonstrate these benefits with respect to extracorporeal anastomosis.

PURPOSE: Laparoscopic ventral rectopexy is the most favored surgical treatment for rectal prolapse. Perineal approaches are recommended for frail patients and those with major comorbidities, and in young men to avoid genitourinary disorders. There are very few descriptions in the literature of transanal endoscopic surgery to treat complete rectal prolapse. The aim of this article is to describe our experience with this technique. PATIENTS AND METHODS: Patients undergoing transanal endoscopic surgery for rectal prolapse repair between 2010 and 2019 were recruited for the study. Preoperative, surgical, and postoperative variables were recorded. Surgical technique, 30-day morbidity and follow-up are described. RESULTS: Five patients have been included. The postoperative period was uneventful and all patients were discharged in 48 hours without complications. All showed improved symptoms at 1-year control, and none presented recurrence in a mean follow-up period of 6 years. CONCLUSIONS: The transanal endoscopic procedure allows improved endoscopic vision, and the reconstruction is performed transpelvically by fixing the anastomosis suture to the pelvic wall to prevent recurrence. Therefore, we think it is a valid alternative to other perineal procedures in patients in whom abdominal surgery is contraindicated.

BACKGROUND: Surgical treatment of early rectal cancer T1 is either local excision or total mesorectal excision. The choice of surgery is based on the risk of metastatic lymph node involvement. The most important factor to consider is the degree of submucosal invasion. We present a different way to measure tumoral invasion derived from the measurement of the healthy residual submucosa with its prognosis and therapeutic implications METHODS: Observational study of tumor submucosal invasion in patients undergoing transanal endoscopic microsurgery was conducted. Parameters evaluated are submucosal invasion, measuring the healthy residual submucosa at the point of maximum invasion; macroscopic morphology of the tumor; presence of muscularis mucosa, muscularis propria, and measurement of submucosa in the tumor area and the healthy area. The classification proposed is compared with the ones previously published. RESULTS: Eighty consecutive patients diagnosed with T1 rectal cancer underwent transanal endoscopic microsurgery. Seventeen tumors (21.3%) were polypoid. En bloc resection was achieved in 77 (96.3%). The muscularis mucosa was present in 28 (35%), and the muscularis propria in 77 (96.3%) (p < 0.001). The healthy residual submucosa in the tumor area measured 2,343 ± 1,869 µm. Agreement was moderate with the Kikuchi classification (kappa 0.58) and very good with the Kudo classification (kappa 0.87). CONCLUSIONS: We describe a method for measuring submucosal invasion in T1 rectal cancer which does not depend on the morphology of the lesion or on the presence of the muscularis mucosa. It can be applied to all T1 classifications of the digestive tract in which the muscularis propria is present.

INTRODUCTION: Transanal endoscopic microsurgery (TEM) is a safe procedure and the rates of intra- and postoperative complications are low. The information in the literature on the management of these complications is limited, and so their importance may be either under- or overestimated (which may in turn lead to under- or overtreatment). The present article reviews the most relevant series of TEM procedures and their complications and describes various approaches to their management. EVIDENCE ACQUISITION: A systematic review of the literature, including TEM series of more than 150 cases each. We analyzed the population characteristics, surgical variables and intraoperative and postoperative complications. EVIDENCE SYNTHESIS: A total of 1043 records were found. After review, 1031 were excluded. The review therefore includes 12 independent cohorts of TEM procedures with a total of 4395 patients. The rate of perforation into the peritoneal cavity was 5.1%, and conversion to abdominal approach was required in 0.8% of cases. The most frequent complications were acute urinary retention (AUR, 4.9%) and rectal bleeding (2.2%). Less common complications included abscesses (0.99%) and rectovaginal fistula (0.62%). Mortality rates were low, with a mean value of 0.29%. CONCLUSIONS: Awareness and knowledge of TEM complications and their management can play an important role in their treatment and patient safety. Here, we present a review of the most important TEM series and their complication rates and describe various approaches to their management.
