ABSTRACT

BACKGROUND: Surgeons work long shifts and are frequently on call. Pressure to make quick and accurate decisions along with the responsibility of performing complex procedures contribute to surgeons' high stress-levels, anxiety and altered empathy level. We aimed to study surgeons' personality and meaning in life at two different centres. METHODS: General surgeons completed 47 questions. Visual analogous scale-items with controlled internal consistency (Cronbach alpha) coefficients varying from .77 to .85 were used from the following scales: Global Measure of Perceived Stress; Hostility Questionnaire; Jefferson Scale of Physician Empathy; Meaning in Life Questionnaire-SF; Rosenberg Self-Esteem Scale; Spielberger State Anxiety Scale and Quality of Work life Scale. Multiple linear regression analyses, parametric or non-parametric tests were employed when considered adequate. RESULTS: Fifty-four participants were recruited from 3 different levels of training. Gender differences in Anxiety, Physician Empathy and presence of meaning in life (MIL-P) were revealed. Junior trainees differed from senior trainees and consultants as regards MIL-P, Anxiety, Stress and work-related factors. The surgeons' self-rated self-esteem was work-related. Surgeons' Quality of Work Life was best predicted by Physician Empathy but also their self-rated Self-Esteem contributed significantly to the prediction. Surgeons' MIL-P was significantly predicted by Physician Empathy and State Anxiety. CONCLUSION: Surgeons' current personality attributes might not apply to all of them. Female surgeons were more empathetic and felt more presence of meaning in life than male surgeons, and men were less anxious than female surgeons. Junior trainees experienced less anxiety than senior trainees but were more stressed than consultants. The most significant predictors of surgeons' personality were their experience of presence of meaning in life along with their level of empathy.

ABSTRACT

INTRODUCTION: The unique pressures of a surgical career put surgeons at particular risk of mental health conditions, including anxiety and depression. Surgeons have previously been shown to have a high prevalence of psychological distress. This study aimed to systematically review the prevalence of anxiety and depression amongst surgeons, and to identify factors that can modify the risk of anxiety and depression in surgeons. METHODS: A 10-year systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines to identify citations related to the keywords "anxiety" OR "depression" AND "surgeon" in PubMed/Medline and ScienceDirect databases. Inclusion and exclusion criteria were applied to produce a final list of citations. RESULTS: Thirty-one citations were included with a total of 11,399 participants. The median percentage of anxiety in surgeons was 20 with a range of 54.6%. While the median percentage of depression was 24 with a range of 59%. Risk factors associated with a higher risk of anxiety and depression include female gender, younger age, concurrent burnout, and occupational concerns regarding the COVID-19 pandemic. Protective factors include institutional support and a sense of social belonging. CONCLUSIONS: There was a high prevalence of anxiety and depression amongst surgeons over the past decade. It is imperative to develop strategies to mitigate the effect of anxiety and depression in surgeons.

ABSTRACT

Acute appendicitis is one of the most common abdominal emergencies. There has been an increasing use of robotic abdominal surgery. However, it remains underutilised in emergency settings. This study aimed to systematically review robotic appendicectomy (RA) feasibility. A 20-year systematic review was performed, along with quality assessment. The research protocol was registered with PROSPERO. The search yielded 1,242 citations, including 9 articles. The mean quality score was 10.72 ± 2.56. The endpoints across the studies were rate of conversion to open surgery, length of hospital stay, blood loss and operative time. RA is a safe, feasible technique that can be performed in elective and emergency settings with minimal blood loss. The operative time and hospital stay were within acceptable limits. Robotic surgery's major drawback is its high cost and limited availability. Future studies evaluating RA with a focus on its application during emergencies and its cost-effectiveness are recommended.

ABSTRACT

INTRODUCTION: Disruptive physician behaviour can affect patients' safety. If surgical trainees throughout higher education experience disruptive behaviour, impaired work-life may follow. Therefore, we aimed to study surgeons' level of narcissism (N), hostility, and stress in relation to their work environment and potential experience of bullying. We also scrutinized search for or presence of meaning in life. METHODS: General surgeons in UK National Health Service from 2 hospitals participated with 3 levels of training: junior trainees (JT), senior trainees (ST), and consultants (CONS). Participants completed 52 VAS-formed questions plus demographics. Modified questionnaires were used for assessments of 'hostility', 'narcissism', meaning in life, quality of work-life, and bullying. RESULTS: Altogether 33% of surgeons displayed narcissism and 22% could exhibit disruptive behaviour. MANOVA significant differences between low, medium, and high narcissism groups were revealed in hostility (p<.01), perceived stress (p=.001), and presence of meaning in life (p<.05). Regression analyses explained hostility both by N-scale (p=.000) and 'being bullied during training'(p=.009) but negatively by 'presence of meaning in life'(p=.004). Surgeons' perceived stress was explained both by N-scale (p=.000) followed by 'seeing others bullied during training (p=.000) and negatively by 'working extra days beyond schedule' (p=.007). The presence of meaning in life was explained mostly by good beneficial stress (p= .000) but negatively both by 'doing extra work beyond schedule' (p= .016) and hostility (p= .003). CONCLUSION: Surgeons may exhibit disruptive behaviour in a challenging situation. The narcissim-scale was the best predictor of hostility and perceived stress. Being bullied during surgical training predicted hostility. Seeing others being bullied during surgical training predicted stress. Beneficial stress is explained best by surgeons' experience of the presence of meaning in life.

ABSTRACT

INTRODUCTION: Racial/ethnic discrimination indicates the stereotyped or unkind conduct of superiority towards other persons based on their race or skin color. The UK General Medical Council published a statement supporting zero-tolerance approach to racism in the workplace. We aimed to systematically review racial discrimination in surgery and answer the following questions: (1) Does racial/ethnic discrimination in surgery exist in citations from the last 5 years. (2) If yes, are ways suggested to reduce racial/ethnic discrimination in surgery? METHODS: The systematic review was performed in compliance with the PRISMA guidelines along AMSTAR 2. A 5-year literature search was carried out on PubMed for articles published from 1/1/2017 to 01/11/2022. Search terms were 'racial discrimination and surgery', 'racism OR discrimination AND surgery', 'racism OR discrimination AND surgical education'. The retrieved citations were quality assessed by MERSQI and evidence graded by GRADE. RESULTS: A total of 9116 participants responded with a mean of 1013 (SD = 2408) responses per citations reported in 9 studies from a final list of 10 included citations. Nine studies were from USA and 1 from South Africa. There was evidence of racial discrimination in the last 5 years and the results were justified on strong scientific evidence constituting the basis for evidence grade I. The second question's answer was 'yes' which was defendable on moderate scientific recommendation and thereby establishing the basis for evidence grade II. CONCLUSION: There was sufficient evidence for the presence of racial discrimination in surgical practice in the last 5 years. Ways to decrease racial discrimination in surgery exist. Healthcare and training systems must increase the awareness of these issues to eliminate the harmful effect on the individual as well as on the level of the surgical team performance. The existence of the discussed problems must be managed in more countries with diverse healthcare systems.

ABSTRACT

Background: Acute cutaneous abscess is a common surgical condition that mostly requires incision and drainage. Despite this, there is no standardized national or international guidance on post-operative antibiotics prescription. Traditionally, antibiotics are not indicated unless complications and/or risk factors such as immunocompromisation, diabetes or cellulitis exist. We aimed to study the local practice for post-operative antibiotics prescription for cutaneous abscesses in a UK university teaching hospital. Methods: Retrospective data collection for emergency general surgical admissions for a period of 6 months was carried out. All patients with cutaneous abscesses were included in this analysis. Scrotal, breast and limb abscesses were excluded. Patients' demographics, co-morbidities and complications, including local (cellulitis, necrosis) and systemic (e.g sepsis), were studied. Approval for access to patient data was granted by the local clinical governance department prior to the commencement of this study. Computations were performed using IBM SPSS version 26. Chi square (X 2), Pearson correlation (r), one or two samples t-test (one or two tailed) were applied. Results: A total of 148 patients were included. The mean age was 40 years (55 % males). The most common site of abscess was perianal (27.7 %), followed by pilonidal (20.3 %) and axilla (16.9 %). A total of 107 (73 %) were managed surgically with incision and drainage, and of these 92 (86 %) were managed within 24 h. Altogether, 83 (76 %) were prescribed post-operative antibiotics, while only 25 (23 %) had indications. The most used post-operative empirical antibiotics was co-amoxiclav (59 %). There was a significant relationship between 'abscess site' × 'antibiotics' [X 2 (36)=54.8, P=0.023]. A total of 103 patients' average duration of post-operative antibiotics was 7.2 (sd 2.9) days. Ten patients subject to readmission spent an average of 8.4 (sd 3.8) days on antibiotics. Conclusions: There were variations in clinical practice regarding post-operative antibiotic prescription for cutaneous abscesses. Research is required in the future in cooperation with microbiologists to develop a standardized evidence-based treatment protocol for the management of such a common surgical condition.

ABSTRACT

BACKGROUND: Postoperative hernia-repair complications are frequent in patients with inflammatory bowel disease (IBD). This fact challenges surgeons' decision about hernia mesh management in these patients. Therefore, we systematically reviewed the hernia mesh repair in IBD patients with emphasis on risk factors for postoperative complications. METHOD: A systematic review was done in compliance with the PRISMA guidelines. A search was carried out on PubMed and ScienceDirect databases. English language articles published from inception to October 2021 were included in this study. MERSQI scores were applied along with evidence grades in agreement with GRADE's recommendations. The research protocol was registered with PROSPERO (CRD42021247185). RESULTS: The present systematic search resulted in 11,243 citations with a final inclusion of 10 citations. One paper reached high and 4 moderate quality. Patients with IBD exhibit about 27% recurrence after hernia repair. Risk factors for overall abdominal septic morbidity in Crohn's disease comprised enteroprosthetic fistula, mesh withdrawals, surgery duration, malnutrition biological mesh, and gastrointestinal concomitant procedure. CONCLUSION: Patients with IBD were subject, more so than controls to postoperative complications and hernia recurrence. The use of a diversity of mesh types, a variety of position techniques, and several surgical choices in the citations left room for less explicit and more implicit inferences as regards best surgical option for hernia repair in patients with IBD.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Bouveret syndrome is a rare condition characterised by gastric outlet obstruction secondary to a gallstone fistulating into the proximal duodenum or pylorus. Although rare, this condition carries a high mortality rate and no current standardised guidelines for management. CASE PRESENTATION: We present a case of a patient in their 60s with recurrent small bowel obstruction secondary to a cholecysto-duodenal fistula and large gallstone which became impacted in the fourth part of the duodenum. The patient had a P-POSSUM Score of 14% mortality and 60% morbidity risk, had multiple co-morbidities, was bedbound, BMI 59 and had been deemed high risk for general anaesthetic at oncology centre for a 10 × 10 cm likely gynaecological malignancy a month prior to this admission. CLINICAL DISCUSSION: In contrast to existing literature, endoscopic lithotripsy was considered but not attempted due to unavailability of this service locally. Surgical intervention was decided based on radiological features of impending duodenal perforation on CT imaging and multiple disciplinary team discussion. The patient was managed with open enterolithotomy at the duodeno-jejunal (DJ) flexure and discharged 3 weeks post-operatively at her pre-operative baseline. CONCLUSION: This is the first report to our knowledge to describe successful surgical management of a gallstone impacted in the fourth part of the duodenum. In cases where anatomical location of impaction precludes retrieval via simple gastrostomy, we suggest using high pressure flush to mobilise the stone to more favourable location distally. We emphasise that stone size should be considered when planning surgical management.

ABSTRACT

BACKGROUND: Patients with advanced illnesses are often admitted with acute surgical emergencies. There is currently no evidence characterising such admissions. We aimed to evaluate emergency patients, managed non-operatively, who died during the same admission. METHODS: This single-centre retrospective, observational study collected data points for a 12 month period including age, prior documented do not resuscitate order (DNAR), existing cancer, Charlson Comorbidity Index, frailty, surgical diagnosis, interval from admission to death and care given. Patients who underwent surgical intervention were excluded. Non-parametric tests were used for statistical analysis. RESULTS: A total of 72 patients were included in this study, of which 68.1% died within 6 days of admission (median 4.0 days). Patients with visceral perforation, obstruction, bowel ischaemia or known malignancy were more likely to die within 6 days than those with pancreatitis, sepsis or new malignancy (median 2 vs 7 days, p < 0.001). Patients with frailty (2 vs 4 days, p = 0.017) and existing DNAR (3 vs 4 days, p = 0.048) died more rapidly than those without. Age and comorbidity index did not impact time to death. CONCLUSION: Frailty, surgical diagnosis and existing DNAR were predictors of shorter admission to death interval, while age and comorbidity index were not. This has implications on inpatient palliative care service planning.

ABSTRACT

Surgery is known to be a craft profession requiring individuals with specific innate aptitude for manipulative skills, and visuospatial and psychomotor abilities. The present-day selection process of surgical trainees does not include aptitude testing for the psychomotor and manual manipulative skills of candidates for required abilities. We aimed to scrutinize the significance of innate aptitudes in surgical practice and impact of training on skills by systematically reviewing their significance on the surgical task performance. A systematic review was performed in compliance with PRISMA guidelines. An initial search was carried out on PubMed/Medline for English language articles published over 20 years from January 2001 to January 2021. Search strategy and terms to be used included 'aptitude for surgery', 'innate aptitude and surgical skills, 'manipulative abilities and surgery', and 'psychomotor skills and surgery'. MERSQI score was applied to assess the quality of quantitatively researched citations. The results of the present searches provided a total of 1142 studies. Twenty-one studies met the inclusion criteria out of which six citations reached high quality and rejected our three null hypothesis. Consequently, the result specified that all medical students cannot reach proficiency in skills necessary for pursuing a career in surgery; moreover, playing video games and/or musical instruments does not promote skills for surgery, and finally, there may be a valid test with predictive value for novices aspiring for a surgical career. MERSQI mean score was 11.07 (SD = 0.98; range 9.25-12.75). The significant findings indicated that medical students with low innate aptitude cannot reach skills necessary for a competent career in surgery. Training does not compensate for pictorial-skill deficiency, and a skill is needed in laparoscopy. Video-gaming and musical instrument playing did not significantly promote aptitude for microsurgery. The space-relation test has predictive value for a good laparoscopic surgical virtual-reality performance. The selection process for candidates suitable for a career in surgery requests performance in a simulated surgical environment.

ABSTRACT

INTRODUCTION: The transmission of COVID-19 virus since the outbreak of viral pneumonia due to SARS-CoV-2 gave rise to protective operative measures. Aerosol generating procedures such as laparoscopic surgery are known to be associated with increased risks of viral transmission to the healthcare workers. The safety of laparoscopy during the pandemic was then debated. We aimed to systematically review the literature regarding the safe use of laparoscopy during COVID-19. METHODS: We performed a systematic search using PubMed and ScienceDirect databases from inception to 1st May, 2020. The following search terms were used: ''laparoscopic surgery and COVID-19''; ''minimally invasive surgery and COVID-19''. Search items were considered from the nature of the articles, date of publication, aims and findings in relation to use of laparoscopic surgery during COVID-19. The study protocol was registered with PROSPERO register for systematic reviews (CRD42020183432). RESULTS: Altogether, 174 relevant citations were identified and reviewed for this study, of which 22 articles were included. The analysis of the findings in relation to laparoscopic surgery during the pandemic were presented in tabular form. We completed the common recommendations for performing laparoscopy during the COVID-19 pandemic in forms of pre-, intra- and postoperative phases. CONCLUSION: There is no scientific evidence to date for the transmission of COVID-19 by laparoscopic surgery. Laparoscopy can be used with precautions because of its benefits compared to open surgery. If safe, conservative management is the primary alternative during the pandemic. We concluded that recommended precautions should be respected while performing laparoscopy during the pandemic.

ABSTRACT

INTRODUCTION: Laparoscopic surgery may be advantageous for cystic fibrosis (CF) patients because it leads to fewer complications than open surgery. However, it could still lead to pulmonary and cardiovascular complications in CF patients. We aimed to systematically review the use of laparoscopic surgery in CF patients. METHODS: A systematic review was performed in compliance with PRISMA guidelines. A literature search was performed using PubMed/MEDLINE, ScienceDirect, EMBASE, and Google Scholar, with "cystic fibrosis and laparoscopic surgery" and "cystic fibrosis and minimally invasive surgery" used as the search terms. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria were applied. The protocol was registered with the PROSPERO register. RESULTS: Six studies met the predetermined inclusion criteria; accordingly, two studies provided high-quality evidence and four provided moderate-quality evidence. The interrater correlation was convincing (rs  = .95, P = .02, two-tailed). Therefore, three quantitative studies and three qualitative studies were assessed and evidence-graded in accordance with the GRADE protocol. CONCLUSION: The benefits of laparoscopic surgical interventions for patients with CF were supported with good evidential value and recognized as a safe and suitable surgical option.

ABSTRACT

INTRODUCTION: Music is commonly played in operating theatres. Music was shown to diminish stress of the surgical team along with reducing the patient's anxiety before surgery. On the other hand, it has been revealed that music might give rise to negative effects of divided attention causing distraction in surgical routines. Therefore, we aimed to systematically review the effect of music on the surgeon's task performance. METHODS: A systematic review was performed in compliance with the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) and AMSTAR (Assessing the methodological quality of systematic reviews) guidelines. A literature search using PubMed/Medline, ScienceDirect and Google Scholar, was performed by means of the search terms: "music and operating theatre", as well as "music and surgery". The search was limited to citations in English from year 2009-2018. Search items were considered from the nature of the articles, date of publication, forum of publication, aims and main findings in relation to use of music in operating theatres. Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria were applied. Studies were included based on predetermined inclusion criteria where after the papers' quality assessments and evidence grading were completed by two independent reviewers. The protocol was registered with the PROSPERO register of systematic reviews. RESULTS: Out of 18 studies that formed the base for evidence evaluations, 6 studies were assessed as having high quality and 8 studies of moderate quality. Five studies, provided both strong and moderate scientific evidence for a positive effect of music on surgeon's task performance. In contrast, strong scientific evidence for a negative effect of music on surgeon's task performance also was revealed in 2 high-quality studies. Nevertheless, the positive effect of music on the surgical task performance was significantly higher when compared to its negative effect (p < 0.0001). CONCLUSION: Certain music elements affect the surgical task performance in a positive or negative way. The total and significant outcome of the present study was that the positive effect of music on surgeon's task performance, overrides its negative effect. Classic music when played with a low to medium volume can improve the surgical task performance by increasing both accuracy and speed. The distracting effect of music should also be put in consideration when playing a loud or high-beat type of music in the operating theatres.

ABSTRACT

AIM: There are reports of visual strains and associated symptoms when operating in a 3D laparoscopic environment. We aimed to study the extent of visual symptoms seen in 3D versus conventional 2D imaging in volunteers performing laparoscopic tasks and study the effect of eye exercises on 3D laparoscopy. METHODS: Twenty four consented laparoscopic novices were required to undergo a visual acuity test (Snellen chart) and eye deviation test (Maddox Wing). A battery of specific isolated laparoscopic tasks lasting 30 min was developed to test their ability to detect changes in 2D and 3D environments separately. Before and after the 2D and 3D laparoscopic tasks, subjects were asked to complete a standardised questionnaire designed to scale (from 0 to 10) their visual symptoms (blurred vision, difficulty in refocusing from one distance to another, irritated or burning eyes, dry eyes, eyestrain, headache and dizziness). Participants who underwent 3D laparoscopic tasks were randomized into two groups, those who received two minutes eye exercises before performing the tasks and those who didn't. Independent t-test was used for the statistical analysis of this study. RESULTS: Visual symptoms and eye strain were significant in 2D (p < 0.01) and difficulty in refocusing from one distance to another was significant in 3D laparoscopic imaging (p < 0.05). There was no significant effect of the simple eye exercises on relieving the visual symptoms in the 3D group. CONCLUSION: Visual symptoms were present in both 2D and 3D imaging laparoscopy. Eye strain was prominent in 2D imaging, while difficulty in refocusing from one distance to another was prominent in 3D. Eye exercises for 3D visual symptoms did not bring any significant improvement.

ABSTRACT

AIMS: There is a strong evidence to suggest that 3D imaging improves the laparoscopic task performance when compared against 2D. However, to date, no study has explained why that might be. We identified six generic visual components during laparoscopic imaging and aimed to study each component in both 2D and 3D environments for comparison. METHODS: Twenty-four consented laparoscopic novices performed specific isolated tasks in a laparoscopic Endo Trainer in 2D and 3D separately. The six endpoints were the accuracy in detecting changes in the laparoscopic images in the following components: distance, area, angle, curvature, volume and spatial coordinates. All the components except the spatial coordinates were assessed by creation, measurement and comparison. Each component was analysed between 2D and 3D groups and within each group at different values. Tests of spatial coordinates were video-recorded and analysed for error number and error types by human reliability analysis technique. Errors types included past-pointing, not reaching the object and touching the wrong object. The results were statistically analysed with independent T test. RESULTS: There was no statistically significant difference between 2D and 3D accuracy in the angle, area, distance and curvature. 3D performed more accurately in comparing volumes (p = 0.05). In spatial coordinates, there were a statistically significant higher number of errors in 2D as compared to 3D (p < 0.001). Past-pointing and touching the wrong objects were significantly higher in 2D (p < 0.05). CONCLUSION: Between all the visual components, detecting change in volume and the spatial coordinates showed significant improvement in 3D environment when compared to 2D.

ABSTRACT

INTRODUCTION: Surgical checklists are in use to reduce errors for safer surgery. We aimed to study the effect of a previously designed performance-based self-administered intra-procedural checklist on the performance of trainees during elective laparoscopic cholecystectomy. METHODS: Twenty-four laparoscopic cholecystectomies were enrolled into the study. Six surgical trainees each performed four procedures, two without the checklist and directly followed by two procedures with the checklist. A soft beeping sound reminded each trainee to apply the checklist every 4 min during the procedures. The unedited videos were analysed using the human reliability analysis technique for the number of consequential errors, number of interventions by the trainer, number of instrument movements and time execution. The trainees' satisfaction was assessed on a 5-point Likert scale questionnaire. Nonparametric test was used for data analysis. p value was defined as significant when p < 0.05. RESULTS: Participants performed statistically better with the application of the checklist compared to when no checklist was used, respectively: Median [IQR] total number of errors 1.51 [0.80] versus 3.84 [1.42] (p = 0.002) and consequential errors 0.20 [0.12] versus 0.45 [0.42] (p = 0.005), and the number of instrument movements per time decreased from 11.90 [5.34] to 10.38 [5.16] (p = 0.04). With the introduction of the checklist, the number of interventions by the trainer per time decreased from 2.79 [1.85] to 0.43 [1.208] (p = 0.003). The trainees satisfaction score was 4.5 [1] for the first question, 4 [1] for the second question and 4 [2] for the third question. CONCLUSION: The self-administered intra-procedural checklist improved the performance of surgical trainees and decreased the number of interventions by the trainer during laparoscopic cholecystectomy. The trainees were generally satisfied using the checklist during the procedures.
