BACKGROUND: Ampullary adenocarcinoma (AAC) is a rare neoplasm which as a result is lacking specific treatment guidelines. This international survey study was performed to gain insight in the current daily practice of AAC.METHODS: Surgeons and medical oncologists, whom were members of the Dutch Pancreatic Cancer Group, International Study Group on Ampullary Cancer, International Hepato-Pancreato-Biliary Association, European and International Consortium on Minimally Invasive Pancreatic Surgery, or contributed to (peri)ampullary cancer research, were invited through email and newsletters between January and October 2021.RESULTS: Overall, 217 surgeons and medical oncologists completed the survey. Most of the respondents work in Europe (60%), and in a pancreatic expertise center (86%). The majority of respondents (87%) stated that the histological AAC subtype (e.g. intestinal vs. pancreatobiliary) was determined in the resection specimen. Neoadjuvant treatment for resectable disease was considered by 24% and adjuvant therapy by 90% of the respondents, with 80% of them choosing adjuvant chemotherapy alone. The formation of multidisciplinary teams, improvement in resection procedures, increased availability of chemotherapy regimens, and increased knowledge on tumor biology were considered as the most important developments in the last five years. The necessity for randomized controlled trials was mentioned by 50% of the respondents.CONCLUSIONS: This international survey highlights the existing variation in the management of patients with AAC, especially regarding the use of (neo)adjuvant therapy. More data from trials and international registries are needed to develop evidence-based guidelines on surgical and oncological management with the ultimate aim to improve outcomes for patients with AAC.

Background The 8th edition of AJCC TNM staging of Gallbladder cancer subdivided T2 stage into T2a and T2b based on tumour location. This meta-analysis aimed to investigate the long-term outcomes in T2a and T2b gallbladder cancers. Methods Literature search of Medline, Web of science, Embase and Cochrane databases was performed. Study characteristics, survival and recurrence data were extracted for meta-analysis of effect estimates and of individual patient data. Results Fifteen retrospective studies (2531 patients, T2a = 1332, T2b = 199) were included in the meta-analysis. Overall survival (OS) was significantly worse in patients with T2b compared to T2a tumours (HR 2.18, 95% CI 1.67–2.86, p < 0.0001). Meta-analysis of individual patient data (n = 629) showed similar results (HR 1.92, 95% CI 1.43–2.58, p < 0.00001). Patients with T2b tumours had higher risk of recurrence compared to T2a (OR 3.19, 95% CI 1.40–7.28, p = 0.006) and were more likely to receive adjuvant chemotherapy (OR 1.76, 95% CI 1.12–2.84, p 0.014). Liver resection improved OS in T2b tumours (HR 2.99, CI 1.73–5.16, p < 0.0001). Conclusion T2b gallbladder tumours have worse overall survival and increase risk of recurrence compared to T2a. Liver resection appears to improve OS in patients with T2b tumours. However, high quality multicentre data is required to confirm these results. Take-home message T2b gallbladder tumours have worse overall survival and increase risk of recurrence compared to T2a. Liver resection appears to improve OS in patients with T2b tumours. However, high quality multicentre data is required to confirm these results.

This study tested the construct validity and reliability of the Scales for Rating the Behavioral Characteristics of Superior Students (SRBCSS) with the purpose to have a valid and reliable measure to identify the gifted individuals. The sample consisted of 176 superior students from grades five and six in Qatar. The results revealed a high consistency in rating the students by their teachers. Confirmatory factor analysis revealed that the items clustered around the 12 subscales. Also, the indicators in form of parcels produced 12 factors and two second-order factors that represent learning/personal and verbal/artistic characteristics. The results showed that those major characteristics are highly correlated and provided support to the convergent validity of the subscales. The implication of these results indicate that the subscales can be used collectively or separately to assess students’ characteristics of superiority in the Arab milieu.

Purpose Moor (1985) designated two major problem sources typifying the social and ethical implications of computer technologies, namely, “policy vacuum” and “conceptual muddles.” Motivated by Moor’s seminal definition and Floridi’s (2013) conceptualization of information and communication technologies (ICTs) as re-ontologizing technologies, this study aims to explore Omani undergraduates’ cognition regarding ICT ethics. Design/methodology/approach Adopting a grounded theory approach for the constant comparative thematic analysis, the constituents of ICT ethics-related cognition among undergraduates and influencing factors were scrutinized. Qualitative data were gathered via focus group discussions with undergraduates and interviews with academics and information systems professionals at Sultan Qaboos University. Findings In total, 10 thematic categories revolving around a core category, constructing conceptual perceptions of and attitudes toward the realms constituting ICT ethics using an ontological, object-oriented approach, emerged from the comparative analysis. Undergraduates were found to adopt an applied approach when defining professional ICT ethics codes and policies, with a particular focus on information privacy and integrity. Research limitations/implications This qualitative study was conducted at a single research site. This may restrict the generalizability of the findings. Postgraduates were not considered when designing this qualitative inquiry. Originality/value The findings of the study hold theoretical and methodological significance with regard to ICT ethics-related cognition in the era following the fourth industrial revolution by sustaining feminist ethics in this research. Ultimately, the study developed a substantive theory scrutinizing the constitutive elements of ICT ethics-related cognition among Generation Z.

Purpose This paper examines associations among the socio-psychological determinants of information and communication technologies (ICT)-assisted deviance-related practices within a group of Omani undergraduates. Moreover, this study aims to evaluate the explanatory burdens of such socio-psychological factors on actual behaviour. Design/methodology/approach The study implements a predictive research design applied to a cross-sectional sample. At the outset, a theoretical model was built based on the theory of planned behaviour (TPB). Thereafter, structural equation modelling was implemented to test the TPB model on the response data collected from a cluster sample of undergraduates from six universities in the Sultanate of Oman. Findings The results of the path diagram overwhelmingly support the TPB hypotheses. Specifically, intention is the most influential and immediate predictor of behaviour, while at the same time partially, though markedly, mediating the influence of cognition on behaviour. Practical implications This study has implications for the design of inclusive measures of the intrinsic dimensions of ethical self-efficacy as designated by the social cognitive theory of moral thought and conduct, which include moral judgment, self-monitoring of conduct and affective reactions to conduct. As the study reveals the importance of the explanatory power of cognition to explain variance in intention and behaviour, it has implications on the development of ICT-ethics-education. Originality/value This study fills a gap in the empirical literature on how intention mediates the relationship between ICT-ethics-connected cognition and behaviour. Moreover, the study addresses the direct relationship between cognition and behaviour – a relationship that is considered equivocal in both theories of planned behaviour and reasoned action.

Background Several studies have suggested a survival benefit of neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) in the pancreatic head. Data concerning NAT for PDAC located in pancreatic body or tail are lacking. Methods Post hoc analysis of an international multicenter retrospective cohort of distal pancreatectomy for PDAC in 34 centers from 11 countries (2007–2015). Patients who underwent resection after NAT were matched (1:1 ratio), using propensity scores based on baseline characteristics, to patients who underwent upfront resection. Median overall survival was compared using the stratified log-rank test. Results Among 1236 patients, 136 (11.0%) received NAT, most frequently FOLFIRINOX (25.7%). In total, 94 patients receiving NAT were matched to 94 patients undergoing upfront resection. NAT was associated with less postoperative major morbidity (Clavien–Dindo ≥ 3a, 10.6% vs. 23.4%, P = 0.020) and pancreatic fistula grade B/C (9.6% vs. 21.3%, P = 0.026). NAT did not improve overall survival [27 (95% CI 14–39) versus 31 months (95% CI 19–42), P = 0.277], as compared with upfront resection. In a sensitivity analysis of 251 patients with radiographic tumor involvement of splenic vessels, NAT (n = 37, 14.7%) was associated with prolonged overall survival [36 (95% CI 18–53) versus 20 months (95% CI 15–24), P = 0.049], as compared with upfront resection. Conclusion In this international multicenter cohort study, NAT for resected PDAC in pancreatic body or tail was associated with less morbidity and pancreatic fistula but similar overall survival in comparison with upfront resection. Prospective studies should confirm a survival benefit of NAT in patients with PDAC and splenic vessel involvement.

Item does not contain fulltext BACKGROUND: A radical left pancreatectomy in patients with pancreatic ductal adenocarcinoma (PDAC) may require extended, multivisceral resections. The role of a laparoscopic approach in extended radical left pancreatectomy (ERLP) is unclear since comparative studies are lacking. The aim of this study was to compare outcomes after laparoscopic vs open ERLP in patients with PDAC. METHODS: An international multicenter propensity-score matched study including patients who underwent either laparoscopic or open ERLP (L-ERLP; O-ERLP) for PDAC was performed (2007-2015). The ISGPS definition for extended resection was used. Primary outcomes were overall survival, margin negative rate (R0), and lymph node retrieval. RESULTS: Between 2007 and 2015, 320 patients underwent ERLP in 34 centers from 12 countries (65 L-ERLP vs. 255 O-ERLP). After propensity-score matching, 44 L-ERLP could be matched to 44 O-ERLP. In the matched cohort, the conversion rate in L-ERLP group was 35%. The L-ERLP R0 resection rate (matched cohort) was comparable to O-ERLP (67% vs 48%; P = 0.063) but the lymph node yield was lower for L-ERLP than O-ERLP (median 11 vs 19, P = 0.023). L-ERLP was associated with less delayed gastric emptying (0% vs 16%, P = 0.006) and shorter hospital stay (median 9 vs 13 days, P = 0.005), as compared to O-ERLP. Outcomes were comparable for additional organ resections, vascular resections (besides splenic vessels), Clavien-Dindo grade ≥ III complications, or 90-day mortality (2% vs 2%, P = 0.973). The median overall survival was comparable between both groups (19 vs 20 months, P = 0.571). Conversion did not worsen outcomes in L-ERLP. CONCLUSION: The laparoscopic approach may be used safely in selected patients requiring ERLP for PDAC, since morbidity, mortality, and overall survival seem comparable, as compared to O-ERLP. L-ERLP is associated with a high conversion rate and reduced lymph node yield but also with less delayed gastric emptying and a shorter hospital stay, as compared to O-ERLP.

Study Purpose The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. Methods The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. Results Not applicable. Conclusion DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

Despite many developments, postoperative bile leakage (POBL) remains a relatively common postoperative complication after laparoscopic liver resection (LLR) and open liver resection (OLR). Previous studies regarding the incidence and clinical impact of POBL have mainly focused on patients undergoing OLR. The aim of this study is to compare the incidence and clinical impact of POBL between patients undergoing LLR and OLR in a large international multicenter cohort using a propensity score matched analysis.

Laparoscopic distal pancreatectomy (LDP) is increasingly being performed as an alternative to open surgery. Whether the implementation and corresponding learning curve of LDP have an impact on patient outcome is unknown. The aim was to investigate the temporal trends in practice across UK centres.This was a retrospective multicentre observational cohort study of LDP in 11 tertiary referral centres in the UK between 2006 and 2016. The learning curve was analysed by pooling data for the first 15 consecutive patients who had LDP and examining trends in surgical outcomes in subsequent patients.In total, 570 patients underwent LDP, whereas 888 underwent open resection. For LDP the median duration of operation was 240 min, with 200 ml blood loss. The conversion rate was 12·1 per cent. Neuroendocrine tumours (26·7 per cent) and mucinous cystic neoplasms (19·7 per cent) were commonest indications. The proportion of LDPs increased from 24·4 per cent in 2006-2009 (P1) to 46·0 per cent in 2014-2016 (P3) (P 0·001). LDP was increasingly performed for patients aged 70 years or more (16 per cent in P1 versus 34·4 per cent in P3; P = 0·002), pancreatic ductal adenocarcinoma (6 versus 19·1 per cent; P = 0·005) and advanced malignant tumours (27 versus 52 per cent; P = 0·016). With increasing experience, there was a trend for a decrease in blood transfusion rate (14·1 per cent for procedures 1-15 to 3·5 per cent for procedures 46-75; P = 0·008), ICU admissions (32·7 to 19·2 per cent; P = 0·021) and median duration of hospital stay (7 (i.q.r. 5-9) to 6 (4-7) days; P = 0·002). After 30 procedures, a decrease was noted in rates of both overall morbidity (57·7 versus 42·2 per cent for procedures 16-30 versus 46-75 respectively; P = 0·009) and severe morbidity (18·8 versus 9·7 per cent; P = 0·031).LDP has increased as a treatment option for lesions of the distal pancreas as indications for the procedure have expanded. Perioperative outcomes improved with the number of procedures performed.Cada día se utiliza más la pancreatectomía distal laparoscópica (laparoscopic distal pancreatectomy, LDP) como una alternativa a la cirugía abierta. Se desconoce si la implementación y la correspondiente curva de aprendizaje de la LDP tienen impacto en los resultados. El objetivo fue investigar las tendencias relacionadas con su implementación en los centros del Reino Unido a los largo del tiempo. MÉTODOS: Se realizó el estudio observacional retrospectivo y multicéntrico de una cohorte de LDP en once centros de referencia terciarios del Reino Unido entre 2006-2016. Se analizó la curva de aprendizaje agrupando los 15 primeros pacientes consecutivos de LDP y se compararon los resultados quirúrgicos con los obtenidos en los pacientes subsiguientes.En total, se incluyeron 570 pacientes con LDP y 888 con resección abierta. Para el LDP, la mediana de tiempo operatorio fue de 240 minutos con 200 ml de pérdida de sangre. La tasa de conversión fue del 12,2%. Las indicaciones más frecuentes fueron los tumores neuroendocrinos (26,7%) y las neoplasias quísticas mucinosas (19,7%). La proporción de LDP aumentó del 24% al 46% (de 2006-2009 a 2014-2016; P 0,001). La LDP se realizó cada vez con mayor frecuencia en pacientes de ≥ 70 años (15,8% versus 34,4%, P = 0,002), en pacientes con adenocarcinoma ductal pancreático (6,5% versus 19,1%, P = 0,005) y en pacientes con tumores malignos avanzados (27,3% versus 51,85%, P = 0,016). Con el aumento de la experiencia, disminuyeron las tendencias de la tasa de transfusión sanguínea (14,1% al 3,5%, P = 0,008), los ingresos en la UCI (32,7% a 19,2%, P = 0.021) y la mediana de la duración de la estancia hospitalaria (7 (rango intercuartílico 5-9) a 6 (rango intercuartilico 4-7) días, P = 0,002). Tras 30 procedimientos, disminuyeron tanto la morbilidad global (57,7% versus 42,2%, P = 0,009) como las tasas de morbilidad grave (21,5% versus 14,6%, P = 0,022). CONCLUSIÓN: La pancreatectomía distal laparoscópica se ha incrementado como una opción de tratamiento para las lesiones del páncreas distal a medida que se han ido ampliando las indicaciones del procedimiento. Los resultados perioperatorios mejoran con el número de procedimientos realizados.

A recent systematic review recommends against the use of any of the current COVID-19 prediction models in clinical practice. To enable clinicians to appropriately profile and treat suspected COVID-19 patients at the emergency department (ED), externally validated models that predict poor outcome are desperately needed.Our aims were to identify predictors of poor outcome, defined as mortality or ICU admission within 30 days, in patients presenting to the ED with a clinical suspicion of COVID-19, and to develop and externally validate a prediction model for poor outcome.In this prospective, multi-center study, we enrolled suspected COVID-19 patients presenting at the EDs of two hospitals in the Netherlands. We used backward logistic regression to develop a prediction model. We used the area under the curve (AUC), Brier score and pseudo-R2 to assess model performance. The model was externally validated in an Italian cohort.We included 1193 patients between March 12 and May 27 2020, of whom 196 (16.4%) had a poor outcome. We identified 10 predictors of poor outcome: current malignancy (OR 2.774; 95%CI 1.682-4.576), systolic blood pressure (OR 0.981; 95%CI 0.964-0.998), heart rate (OR 1.001; 95%CI 0.97-1.028), respiratory rate (OR 1.078; 95%CI 1.046-1.111), oxygen saturation (OR 0.899; 95%CI 0.850-0.952), body temperature (OR 0.505; 95%CI 0.359-0.710), serum urea (OR 1.404; 95%CI 1.198-1.645), C-reactive protein (OR 1.013; 95%CI 1.001-1.024), lactate dehydrogenase (OR 1.007; 95%CI 1.002-1.013) and SARS-CoV-2 PCR result (OR 2.456; 95%CI 1.526-3.953). The AUC was 0.86 (95%CI 0.83-0.89), with a Brier score of 0.32 and, and R2 of 0.41. The AUC in the external validation in 500 patients was 0.70 (95%CI 0.65-0.75).The COVERED risk score showed excellent discriminatory ability, also in an external validation. It may aid clinical decision making, and improve triage at the ED in health care environments with high patient throughputs.

Background Minimally invasive pancreatoduodenectomy (MIPD) is increasingly being performed because of perceived patient benefits. Whether conversion of MIPD to open pancreatoduodenectomy worsens outcome, and which risk factors are associated with conversion, is unclear. Methods This was a post hoc analysis of a European multicentre retrospective cohort study of patients undergoing MIPD (2012–2017) in ten medium-volume (10–19 MIPDs annually) and four high-volume (at least 20 MIPDs annually) centres. Propensity score matching (1 : 1) was used to compare outcomes of converted and non-converted MIPD procedures. Multivariable logistic regression analysis was performed to identify risk factors for conversion, with results presented as odds ratios (ORs) with 95 per cent confidence intervals (c.i). Results Overall, 65 of 709 MIPDs were converted (9.2 per cent) and the overall 30-day mortality rate was 3.8 per cent. Risk factors for conversion were tumour size larger than 40 mm (OR 2.7, 95 per cent c.i.1.0 to 6.8; P = 0.041), pancreatobiliary tumours (OR 2.2, 1.0 to 4.8; P = 0.039), age at least 75 years (OR 2.0, 1.0 to 4.1; P = 0.043), and laparoscopic pancreatoduodenectomy (OR 5.2, 2.5 to 10.7; P Conclusion Risk factors for conversion during MIPD include age, large tumour size, tumour location, laparoscopic approach, and surgery in medium-volume centres. Although conversion during MIPD itself was not associated with worse outcomes, the outcome in these patients was poor in general which should be taken into account during patient selection for MIPD.

It may aid clinical decision making, and improve triage at the ED in health care environments with high patient throughputs.

Background Surgical factors, including resection of Gerota’s fascia, R0-resection, and lymph node yield, may be associated with survival after distal pancreatectomy (DP) for pancreatic ductal adenocarcinoma (PDAC), but evidence from large multicenter studies is lacking. This study aimed to identify predictors for overall survival after DP for PDAC, especially those related to surgical technique. Patients and Methods Data from an international retrospective cohort including patients from 11 European countries and the USA who underwent DP for PDAC (2007–2015) were analyzed. Cox proportional hazard analyses were performed and included Gerota’s fascia resection, R0 resection, lymph node ratio, extended resection, and a minimally invasive approach. Results Overall, 1200 patients from 34 centers with median follow-up of 15 months [interquartile range (IQR) 5–31 months] and median survival period of 30 months [95% confidence interval (CI), 27–33 months] were included. Gerota’s fascia resection [hazard ratio (HR) 0.74; p = 0.019], R0 resection (HR 0.70; p = 0.006), and decreased lymph node ratio (HR 0.28; p p p = 0.350). Adjuvant chemotherapy (HR 0.67; p = 0.003) was also associated with improved overall survival. Conclusions This international cohort identified Gerota’s fascia resection, R0 resection, and decreased lymph node ratio as factors associated with improved overall survival during DP for PDAC. Surgeons should strive for R0 resection and adequate lymphadenectomy and could also consider Gerota’s fascia resection in their routine surgical approach.

Purpose The reported conversion rates for minimally invasive distal pancreatectomy (MIDP) range widely from 2 to 38%. The identification of risk factors for conversion may help surgeons during preoperative planning and patient counseling. Moreover, the impact of conversion on outcomes of MIDP is unknown. Methods A systematic review was conducted as part of the 2019 Miami International Evidence-Based Guidelines on Minimally Invasive Pancreas Resection (IG-MIPR). The PubMed, Cochrane, and Embase databases were searched for studies concerning conversion to open surgery in MIDP. Results Of the 828 studies screened, eight met the eligibility criteria, resulting in a combined dataset including 2592 patients after MIDP. The overall conversion rate was 17.1% (range 13.0–32.7%) with heterogeneity between studies associated with the definition of conversion adopted. Only one study divided conversion into elective and emergency conversion. The main indications for conversion were vascular involvement (23.7%), concern for oncological radicality (21.9%), and bleeding (18.9%). The reported risk factors for conversion included a malignancy as an indication for surgery, the proximity of the tumor to vascular structures in preoperative imaging, higher BMI or visceral fat, and multi-organ resection or extended resection. Contrasting results were seen in terms of blood loss and length of stay in comparing converted MIDP and completed MIDP patients. Conclusion The identified risk factors for conversion from this study can be used for patient selection and counseling. Surgeon experience should be considered when contemplating MIDP for a complex patient. Future studies should divide conversion into elective and emergency conversion.

Background In the past infectious diseases affected the quality of lifestyle during home confinement. The study conducted examines the influence of home confinement during the COVID-19 pandemic outbreak on lifestyle, mental wellbeing, nutritional status, and sleeping pattern. Method An online multicategorical questionnaire was distributed to collect demographic information combined with the following tools: Food Frequency Questionnaire (FFQ), International Physical Activity Questionnaire (IPAQ), WHO-5 wellbeing score, and Pittsburgh Sleep Quality Index (PSQI). A snowball non-discriminate sampling procedure was conducted to collect data from people attending or working at higher institutions from March 1, 2020 to April 24, 2020. A total of 1723 completed responses (917 males, 37.4 ±13.4 years old and 806 females 32.2 ± 11.5 years old) were collected. Results The female participants had significantly lower mental health scores than males (53.9% vs. 46.1%). The mental wellbeing scores were higher among participants with medium and high physical activity (PA) levels (p < 0.00). Additionally, the mental wellbeing scores were significantly improved by dietary quality and it’s sleeping score (p < 0.001). However, PA was by far the major determinant of the mental health scores. Conclusion Factors such as PA, diet, and sleeping patterns were associated with mental wellbeing during the COVID-19 confinement among Arab participants.

Background Based on excellent outcomes from high-volume centres, laparoscopic liver resection is increasingly being adopted into nationwide practice which typically includes low-medium volume centres. It is unknown how the use and outcome of laparoscopic liver resection compare between high-volume centres and low-medium volume centres. This study aimed to compare use and outcome of laparoscopic liver resection in three leading European high-volume centres and nationwide practice in the Netherlands. Method An international, retrospective multicentre cohort study including data from three European high-volume centres (Oslo, Southampton and Milan) and all 20 centres in the Netherlands performing laparoscopic liver resection (low-medium volume practice) from January 2011 to December 2016. A high-volume centre is defined as a centre performing >50 laparoscopic liver resections per year. Patients were retrospectively stratified into low, moderate- and high-risk Southampton difficulty score groups. Results A total of 2425 patients were included (1540 high-volume; 885 low-medium volume). The median annual proportion of laparoscopic liver resection was 42.9 per cent in high-volume centres and 7.2 per cent in low-medium volume centres. Patients in the high-volume centres had a lower conversion rate (7.4 versus 13.1 per cent; P Conclusion High-volume expert centres had a sixfold higher use of laparoscopic liver resection, less conversions, and shorter hospital stay, as compared to a nationwide low-medium volume practice. Stratification into Southampton difficulty score risk groups identified some differences but largely outcomes appeared better for high-volume centres in each risk group.

Background/objectives: The aim of this study was to assess the impact of older age (≥70 years) and obesity (BMI ≥30) on surgical outcomes of minimally invasive pancreatic resections (MIPR). Subsequently, open pancreatic resections or MIPR were compared for elderly and/or obese patients. Methods: A systematic review was conducted as part of the 2019 Miami International Evidence-Based Guidelines on MIPR (IG-MIPR). Study quality assessment was according to The Scottish Intercollegiate Guidelines Network (SIGN). A meta-analysis was performed to assess the impact of MIPR or open pancreatic resections in elderly patients. Results: After screening 682 studies, 13 observational studies with 4629 patients were included. Elderly patients undergoing laparoscopic distal pancreatectomy (LDP) had less blood loss (117 mL, p < 0.001) and a shorter hospital stay (3.5 days p < 0.001) than elderly patients undergoing open distal pancreatectomy (ODP). Postoperative pancreatic fistula (POPF) B/C, major complication and reoperation rate were not significantly different in elderly patients undergoing either laparoscopic or open pancreatoduodenectomy (OPD). One study compared robot PD with OPD in obese patients, indicating that patients with robotic surgery had less blood loss (mean 250 ml vs 500 ml, p = 0.001), shorter operative time (mean 381 min vs 428 min, p = 0.003), and lower rate of POPF B/C (13% vs 28%, p = 0.039). Conclusion: The current available limited evidence does not suggest that MIPR is contraindicated in elderly or obese patients. Additionally, outcomes in MIPR are equal or more beneficial compared to the open approach when applied in these patient groups.

espanolIntroduccion. El proposito de este estudio fue examinar si la percepcion del valor de la en- senanza y la autoeficacia de un profesor estan relacionadas con el agotamiento. Investigacio- nes anteriores han demostrado una fuerte relacion entre la autoeficacia de los profesores y el agotamiento. Sin embargo, en raras ocasiones, el valor del trabajo se ha incluido en cualquiera de los estudios anteriores. Metodo. Se extrajo una muestra aleatoria estratificada (N = 2446) de maestros omanies. Se utilizaron tres medidas: valor del trabajo, inventario de agotamiento de Maslach (MBI) y es- cala de sentido de eficacia de los maestros (TSES). Se realizo un analisis factorial confirmato- rio para probar la estructura factorial propuesta de las medidas, asi como el modelo estructural propuesto. Resultados. Las pruebas de invariancia demostraron que la estructura de constructos y las relaciones entre constructos eran invariantes en todos los generos. El valor del trabajo quedo relacionado significativamente con las dimensiones de SE y de agotamiento. De acuerdo con las predicciones, la SE del compromiso de los estudiantes se relaciona con las tres dimensio- nes de agotamiento; mientras que las otras dos dimensiones de SE no se relacionaron con las dimensiones de agotamiento en la direccion esperada. El valor del trabajo y la SE explicaron variaciones significativas en cada una de las dimensiones de agotamiento. Discusion y Conclusion. Los resultados de este estudio resaltan la importancia del valor en el trabajo y la SE de involucrar a los estudiantes como mecanismos cognitivos de autorregula- cion utilizados en situaciones estresantes como la ensenanza y para ayudar a controlar el es- tres y el agotamiento. El Ministerio de Educacion, los medios de comunicacion y la sociedad en general deberian conocer el estado social de la ensenanza y los maestros y brindar mas respeto a los maestros y a su trabajo. Tal respeto mejoraria la moral de los docentes y los ayu- daria a ser mas eficaces y menos exaltados. EnglishIntroduction. The purpose of this study was to examine if the perception of teaching value and a teacher's self-efficacy (SE) are related to burnout. Previous research has shown a strong relation between teachers SE and burnout. Rarely, however, job value has been included in any of the previous studies. Method. A stratified random sample (N =2446) of Omani teachers was drawn. Three measures: Job value, Maslach burnout inventory (MBI) and the teachers' sense of efficacy scale (TSES) were used. Confirmatory factor analysis was performed to test the proposed factor structure of the measures as well as the proposed structural model. Results. The invariance tests proved that the structure of constructs and the relations between constructs were invariant across gender. Job value significantly related to both SE and burn- out dimensions. Consistent with predictions, SE of student engagement related to all three burnout dimensions; whereas the other two dimensions of SE didn’t relate to burnout dimen- sions in the expected direction. Job value and SE explained significant variances in each of the burnout dimensions. Discussion and Conclusion. The results of this study highlight the importance of job value and SE of engaging students as cognitive self-regulatory mechanisms used in the stressful situations like teaching and to help control stress and burnout. Ministry of education, media and socity at large should be aware of the social status of teaching and teachers and provide more respect to the teachers and their job. Such respect would improve the morale of teachers and help them become more efficacious and less exhausted.
