Junior doctors' wellbeing at peak and post-peak pandemic: a repeated cross-sectional study.

INTRODUCTION: The impact of the COVID-19 pandemic on healthcare professionals has been significant. The aim of this study was to explore the mental state and wellbeing of UK junior doctors at different phases of the initial outbreak. METHODS: This is a cross-sectional study of UK-based junior doctors' perceptions of threat and support during and after the first wave of the COVID-19 pandemic. Levels of anxiety, depression, post-traumatic stress disorder symptoms and use of coping mechanisms were explored through a Google questionnaire. RESULTS: 196 participants were included in this study (93 in period A and 103 in period B). Junior doctors reported feeling increased risk (p=0.001) and increased fear of contracting the virus (p<0.001) during period A. Increased levels of severe anxiety (Generalized Anxiety Disorder-7 score >15) along with increased cases level of depression (Patient Health Questionnaire-9 score >10) were reported for both periods. Junior doctors described suffering more frequently with flashbacks (p=0.006) and nightmares (p=0.024) in comparison with senior colleagues during period A. During period A, 21.4% of participants felt isolated at work (p<0.001), whereas 13% reported being easily annoyed on a daily basis, 11.7% reported very low morale (p<0.001) and 66% were not aware of any psychological support being available. The use of exercise, peer support and mindfulness apps increased during period B (p=0.023). CONCLUSIONS: Healthcare systems need to urgently establish robust psychological support mechanisms and infrastructure to protect junior doctors and provide institutional resilience against the adverse consequences of the long physical and mental battle with COVID-19.

Laparoscopic surgery reduces the incidence of surgical site infections compared to the open approach for colorectal procedures: a meta-analysis.

BACKGROUND: Surgical site infections (SSI) are the commonest healthcare associated infections. They severely compromise patient safety, are a significant burden on healthcare resources and have an adverse impact on patient quality of life. The incidence of SSIs can be as high as 10% after colorectal procedures. The laparoscopic approach is being increasingly used to undertake colorectal procedures. It provides advantages over the traditional open approach with smaller incisions, shorter hospital stay and equal oncological outcomes. The aim of this meta-analysis was to evaluate whether the laparoscopic approach for colorectal procedures reduces the incidence of SSI compared to the open approach. METHODS: Randomised controlled trials (RCTs) comparing the two approaches published since 2000 were included in the review. Revman 5.3 software was used to carry out the review. Data were pooled and the results were shown as risk ratios with 95% confidence intervals using the fixed effects model. RESULTS: Sixteen RCT's were included in the analysis comprising 5797 patients. These covered a range of colorectal pathologies including colon cancer, rectal cancer, inflammatory bowel disease and familial adenomatous polyposis syndrome. Analysis showed significantly lower wound infection rates (RR: 0.72, 95% confidence interval: 0.60-0.88, p = 0.001) and lower abdominal abscess rates (RR: 0.88, 95% CI 0.62-1.27, p = 0.51). The combined SSI rate was significantly lower in laparoscopic compared to open surgery (RR: 0.76, 95% CI 0.64-0.90, p = 0.001). CONCLUSIONS: Laparoscopic colorectal surgery significantly lowers the incidence of SSI compared to open surgery.

Factors associated with burnout syndrome in surgeons: a systematic review.

INTRODUCTION: To date, studies have shown a high prevalence of burnout in surgeons. Various factors have been found to be associated with burnout, and it has significant consequences personally and systemically. Junior doctors are increasingly placing their own health and wellbeing as the most important factor in their decisions about training. Finding ways to reduce and prevent burnout is imperative to promote surgical specialties as attractive training pathways. METHODS: The MEDLINE, PsychInfo and EMBASE databases were searched using the subject headings related to surgery and burnout. All full text articles that reported data related to burnout were eligible for inclusion. Articles which did not use the Maslach Burnout Inventory or included non-surgical groups were excluded; 62 articles fulfilled the criteria for inclusion. FINDINGS: Younger age and female sex tended to be associated with higher levels of burnout. Those further in training had lower levels of burnout, while residents suffered more than their seniors. Burnout is associated with a lower personal quality of life, depression and alcohol misuse. Academic work and emotional intelligence may be protective of burnout. Certain personality types are less likely to be burnt out. Mentorship may reduce levels of burnout. CONCLUSIONS: Workload and work environment are areas that could be looked at to reduce job demands that lead to burnout. Intervening in certain psychological factors such as emotional intelligence, resilience and mindfulness may help to reduce burnout. Promoting physical and mental health is important in alleviating burnout, and these factors likely have a complex interplay.

Outcomes of endoscopic pilonidal sinus treatment (EPSiT): a systematic review.

BACKGROUND: Pilonidal sinus is a common disease of the natal cleft, which can lead to complications including infection and abscess formation. Various operative management options are available, but the ideal technique is still debatable. More recently minimally invasive approaches have been described. Our aim was to review the current literature on endoscopic pilonidal sinus treatment (EPSiT) and its outcomes. METHODS: A systematic literature review was conducted and reported in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of EMBASE, MEDLINE and Cochrane Library was conducted in November 2017. Full-text studies on the use of endoscopy for the treatment of pilonidal sinus were included in the review. RESULTS: Initial search results returned 52 articles. Eight studies (eight case series and one randomised control trial) were included in the final qualitative synthesis. These studies demonstrated that EPSiT has good complete healing rates and low recurrence rates. There was also a high level of patient satisfaction and little time taken off work. Two studies reported modifications to the original technique. The main limitation was the lack of comparative studies. CONCLUSIONS: Initial studies on EPSiT have shown promising results. However, there is a need for a standardised technique and more comparative studies to validate this novel procedure.

Magnetic resonance based texture parameters as potential imaging biomarkers for predicting long-term survival in locally advanced rectal cancer treated by chemoradiotherapy.

AIM: The study aimed to investigate whether textural features of rectal cancer on MRI can predict long-term survival in patients treated with long-course chemoradiotherapy. METHOD: Textural analysis (TA) using a filtration-histogram technique of T2-weighted pre- and 6-week post-chemoradiotherapy MRI was undertaken using TexRAD, a proprietary software algorithm. Regions of interest enclosing the largest cross-sectional area of the tumour were manually delineated on the axial images and the filtration step extracted features at different anatomical scales (fine, medium and coarse) followed by quantification of statistical features [mean intensity, standard deviation, entropy, skewness, kurtosis and mean of positive pixels (MPP)] using histogram analysis. Cox multiple regression analysis determined which univariate features including textural, radiological and histological independently predicted overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS). RESULTS: MPP [fine texture, hazard ratio (HR) 6.9, 95% CI: 2.43-19.55, P < 0.001], mean (medium texture, HR 5.6, 95% CI: 1.4-21.7, P = 0.007) and extramural venous invasion (EMVI) on MRI (HR 2.96, 95% CI: 1.04-8.37, P = 0.041) independently predicted OS while mean (medium texture, HR 4.53, 95% CI: 1.58-12.94, P = 0.003), MPP (fine texture, HR 3.36, 95% CI: 1.36-8.31, P = 0.008) and threatened circumferential resection margin (CRM) on MRI (HR 3.1, 95% CI: 1.01-9.46, P = 0.046) predicted DFS. For OS, EMVI on MRI (HR 4.23, 95% CI: 1.41-12.69, P = 0.01) and for DFS kurtosis (medium texture, HR 3.97, 95% CI: 1.44-10.94, P = 0.007) and CRM involvement on MRI (HR 3.36, 95% CI: 1.21-9.32, P = 0.02) were the independent post-treatment factors. Only TA independently predicted RFS on pre- or post-treatment analyses. CONCLUSION: MR based TA of rectal cancers can predict outcome before undergoing surgery and could potentially select patients for individualized therapy.

The incidence of incisional hernias following ileostomy reversal in colorectal cancer patients treated with anterior resection.

INTRODUCTION The aim of this study was to identify the rate of incisional hernia formation following ileostomy reversal in patients who underwent anterior resection for colorectal cancer. In addition, we aimed to ascertain risk factors for the development of reversal-site incisional hernias and to record the characteristics of the resultant hernias. MATERIALS AND METHODS Using a prospectively compiled database of colorectal cancer patients who were treated with anterior resection, we identified individuals who had undergone both ileostomy formation and subsequent reversal of their ileostomies from January 2005 to December 2014. Medical records were reviewed to record descriptive patient data about risk factors for hernia formation, operative details and any subsequent operations. Computed tomography reports were reviewed to identify the number, site and characteristics of incisional hernias. RESULTS A total of 121 patients were included in this study; 14.9% (n = 18) developed an incisional hernia at the ileostomy reversal site; 17.4% (n = 21) at a non-ileostomy site and 6.6% (n = 8) developed both. The reversal-site hernias were smaller both in width and length compared with the non-ileostomy-site hernias. Risk factors for the development of reversal-site incisional hernias were higher body mass index (BMI), lower age, open surgery, longer reversal time and a history of previous hernias. We did not detect a difference in the size of the incisional hernias that developed in patients with these specific risk factors. CONCLUSIONS Incisional hernias are a significant complication of ileostomy reversal. Further evaluation of the use of prophylactic mesh to reduce the incidence of incisional hernias may be worthwhile.

What happens when we do not operate? Survival following conservative bowel cancer management.

Introduction While surgery is the cornerstone of bowel cancer treatment, it comes with significant risks. Among patients aged over 80 years, 30-day mortality is 13%-15%, and additionally 12% will not return home and go on to live in supportive care. The question for patients and clinicians is whether operative surgery benefits elderly, frail patients. Methods Multidisciplinary team outcomes between October 2010 and April 2012 were searched to conduct a retrospective analysis of patients with known localised colorectal cancer who did not undergo surgery due to being deemed unfit. Results Twenty six patients survived for more than a few weeks following surgery, of whom 20% survived for at least 36 months. The average life expectancy following diagnosis was 1 year and 176 days, with a mean age at diagnosis of 87 years (range 77-93 years). One patient survived for 3 years and 240 days after diagnosis. Conclusions Although surgeons are naturally focused on surgical outcomes, non-operative outcomes are equally as important for patients. Elderly, frail patients benefit less from surgery for bowel cancer and have higher risks than younger cohorts, and this needs to be carefully discussed when jointly making the decision whether or not to operate.

Problems and solutions in delivering global surgery in the 21st century.

BACKGROUND: Surgery has had low priority in global health planning, so the delivery of surgical care in low- and middle-income countries is often poorly resourced. A recent Lancet Commission on Global Surgery has highlighted the need for change. METHODS: A consensus view of the problems and solutions was identified by individual surgeons from high-income countries, familiar with surgical care in remote and poorer environments, based on recent publications related to global surgery. RESULTS: The major issues identified were: the perceived unimportance of surgery, shortage of personnel, lack of appropriate training and failure to establish surgical standards, failure to appreciate local needs and poor coordination of service delivery. CONCLUSION: Surgery deserves a higher priority in global health resource allocation. Lessons learned from participation in humanitarian crises should be considered in surgical developments.

Incisional hernia rate after laparoscopic colorectal resection is reduced with standardisation of specimen extraction.

INTRODUCTION: Incisional hernia is a common complication of laparoscopic colorectal surgery. Extraction site may influence the rate of incisional hernias. Major risk factors for the development of incisional hernias include age, diabetes, obesity and smoking status. In this study, we investigated the effect of specimen extraction site on incisional hernia rate. METHODS: Two cohorts of patients who underwent laparoscopic colorectal resections in a single centre in 2005 (n=85) and 2009 (n=139) were studied retrospectively. In 2005 all specimens were extracted through transverse muscle cutting incisions. In 2009 all specimens were extracted through midline incisions. Demographic variables, rate of incisional hernias and risk factors for hernia development were compared between the year groups. All patients had been followed up clinically for two years. RESULTS: A total of 224 patients (mean age: 67.5 years, standard deviation: 16.35 years) were included in this study. Of these, 85 patients were in the 2005 transverse group and 139 were in the 2009 midline group. The total incisional hernia rate for the series was 8.0% at the two-year follow-up visit. For the 2005 group, the incisional hernia rate was 15.3% (n=13) and for the 2009 group, it was 3.6% (n=5) (p<0.01). The body mass index was higher in patients who developed incisional hernias than in those who did not (p=0.02). CONCLUSIONS: The 2005 group had a significantly higher incisional hernia rate than the 2009 group. This is due to the differences in the incision technique and extraction site between the two groups.

Laparoscopic total mesorectal excision following long course chemoradiotherapy for locally advanced rectal cancer.

PURPOSE: Laparoscopic total mesorectal excision (TME) of locally advanced rectal cancer after long-course chemoradiotherapy (LCRT) is surgically and oncologically challenging. We have assessed the feasibility, timing, and short-term oncological outcome of laparoscopic TME after LCRT. METHODS: Between 2004 and 2006, 30 patients were selected for LCRT based on clinical examination and MRI. Patients received 3/4 field radiotherapy, 45-50.4 Gy in 25-28 fractions during 5 weeks with either 5-fluorouracil or Uftoral. Clinical assessments were made 4 weeks after completion of radiotherapy and then 2 weekly with sequential 4 weekly MRI, to individualize the timing of surgery at maximal response. Laparoscopic TME was performed using a standard technique. RESULTS: Thirty patients received LCRT and 26 patients (21 men; median age, 63 years) underwent laparoscopic TME at 11 weeks (median) after LCRT. Median operating time was 270 min. Sixteen patients had LAR and ten had APR. There were three conversions. Three patients developed anastomotic leak (18.7%): one was managed conservatively and one patient died of septicemia. Morbidity was seen in 19% of patients. There were 25 (96%) R0 resections with a complete response in 5 (19%) cases and microscopic tumor in lakes of mucin (Tmic) in another 6 (23%). Two patients (7.6%) developed local recurrence (median follow up, 34 months). The median time interval between radiotherapy and surgery was 11 (range, 7-13) weeks, which was based on serial MRI scans after LCRT. CONCLUSIONS: Laparoscopic TME after LCRT is feasible and safe both oncologically and surgically. Serial MRI helps to determine the optimum timing of surgery.

Incisional hernia rates following laparoscopic colorectal resection.

INTRODUCTION: In published series with satisfactory follow-up incisional hernia rates following laparotomy vary between 4 and 18%, with up to 75% developing within two years of operation. This therefore represents the commonest complication following open abdominal surgery and a substantial added workload for the colorectal/general surgeon. AIM: To prospectively review incisional hernia rates in patients undergoing laparoscopic colorectal resection in a single centre. METHODS: All laparoscopic wounds were closed in identical fashion to open closure technique, utilising 0-monofilament, polyglyconate and a mass closure technique, followed by a subcuticular, polyglactin-910 suture for skin closure. All patients were subsequently examined in an outpatient setting by a senior surgeon independent to the original procedure. RESULTS: 167 consecutive patients undergoing laparoscopic colorectal resections (94M:73F; median age 68 years) were included. Median incision length for specimen extraction was 6 cm (range 3-11 cm) and patients were followed-up for a median of 36 months (range 24-77 months). Twelve (7%) patients developed an incisional hernia (ten in specimen extraction wounds and two in port-site wounds), ten of whom underwent successful laparoscopic repairs. Of the remaining patients, one remains symptomatic and awaits repair, and one is asymptomatic and unfit for surgery. CONCLUSIONS: The well-documented advantages of laparoscopic surgery include reduced hospital stay, early return to activity, decreased analgesic requirements and improved cosmesis. However, the results of this study suggest that incisional hernia rates are not decreased by laparoscopic surgery, although the hernias may be smaller and more amenable to repair by laparoscopic approaches.

Consensus statement: natural orifice transluminal endoscopic surgery.

Natural orifice transluminal endoscopic surgery (NOTES) has generated healthy and vigorous debate about the introduction of an entirely novel method of surgical therapy. Although there are many reasons for scepticism, there is undoubted interest in this field from both the medical profession and general public. Those Associations currently involved in laparoscopic and endoscopic surgery wish to safeguard patients and the reputation of the profession by issuing clear guidance and support for those wishing to undertake NOTES. The purpose of this document is to review the current status of both NOTES and hybrid NOTES, while at the same time identifying obstacles in both clinical research and training. Furthermore, it aims to provide a consensus statement on behalf of the main UK specialty associations involved in this field of surgery. The primary aim of this consensus statement is to provide a framework within which to develop, safely and effectively, what must still be considered an experimental technique.

Locally advanced rectal cancer: histopathological correlation and predictive accuracy of serial MRI after neoadjuvant chemotherapy.

The accuracy of MRI after long-course chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC) has been questioned. We have evaluated our experience of sequential MRI to assess pre-operative downstaging with histopathology correlation. 17 patients with LARC had three MRI scans: MRI 1, before treatment; MRI 2, 6 weeks post-CRT; and MRI 3, pre-operatively. MRI T and N staging were reported, with T3 subdivided into T3a (<5 mm through wall), T3b (1-5 mm), T3c (5-15 mm) and T3d (>15 mm). The maximal wall measurements and a prediction of vascular involvement were also correlated with histopathology. Histopathological agreement with MRI 3 was high: T 82%; N 88% and vascular 73%. Statistically significant (p<0.01) T downstaging was shown in MRI 2 and MRI 3 groups. In the 6 weeks post-CRT scan, T downstaging occurred in 6% of patients, with a further 29.4% showing T3c to T3b downsizing. 41% showed N stage improvement. In the third MRI group pre-surgery, 41.2% showed an MRI T stage improvement, with a further T3 downsizing in 17.6% of patients. 50% of these responders had shown no T stage improvement on their second scan. The sequential scans also showed significant reduction in wall thickness (p<0.01). In conclusion, the pre-operative MRI showed ongoing response to CRT up to 12 weeks post-CRT, which has important clinical implications regarding the most appropriate time to operate. Improved agreement between MRI 3 and histopathology compared with previous studies including only one post-treatment MRI was also demonstrated.

The use of laparoscopic subtotal cholecystectomy for complicated cholelithiasis.

BACKGROUND: The risk of damage to the bile duct and structures in the hilum of the liver is significant when Calot's triangle cannot be safely dissected during laparoscopic cholecystectomy, and conversion to an open procedure often is performed. This is more common during emergency surgery, but may not render the procedure any easier. Traditionally, open subtotal cholecystectomy was performed, but with the advent of laparoscopic surgery, this has fallen from favor. The authors report their experience using laparoscopic subtotal cholecystectomy to avoid bile duct injury and conversion in difficult cases. METHODS: Laparoscopic subtotal cholecystectomy, performed when the cystic duct cannot be identified safely, consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain into Hartmann's pouch. The notes for all patients who underwent a laparoscopic subtotal cholecystectomy between 1 September 2001 and 31 December 2004 were retrospectively analyzed. RESULTS: Subtotal cholecystectomy was performed in 26 cases including 13 emergency and 13 elective procedures. The median age of the patients (15 women and 11 men) was 68 years (range, 36-86 years). The indications were severe fibrosis in 16 cases, inflammatory mass or empyema in 8 cases, and gangrenous gallbladder or perforation in 2 cases. The median postoperative inpatient stay was 5 days (range, 2-26 days). Five patients underwent postoperative endoscopic retrograde cholangiopancreatography: four for persistent biliary leak and one for a retained common bile duct stone. One patient required laparotomy for subphrenic abscess, and one patient (American Society of Anesthesiology [ASA] grade 4, presenting with biliary peritonitis) died 2 days postoperatively. One patient required a subsequent completion laparoscopic cholecystectomy for a retained gallstone. One patient had a chest infection, and two patients experienced port-site hernias. CONCLUSIONS: Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot's triangle cannot be dissected. It averts the need for a laparotomy.

Laparoscopic resection of diverticular fistulae: a 10-year experience.

OBJECTIVE: Until recently the laparoscopic approach was reserved for uncomplicated diverticular disease. We show that fistulating diverticular disease can be resected safely, with good clinical outcome via a laparoscopic approach. METHOD: Between April 1994 and May 2005, 31 consecutive patients [17 male, median age of 63 years (range 40-85)], underwent attempted laparoscopic resection for diverticular fistulae. Patient data were prospectively recorded. RESULTS: There were 22 colovesical and nine colovaginal fistulae. The median operative time was 150 min (range 60-310) and the median postoperative stay was 7 days (range 3-21). Conversion to an open procedure was required in nine of 31 patients (29%). This rate fell to 10% in cases performed after April 2000. There were two nonsurgically related postoperative deaths. Both occurred in the converted group. At 3 months follow-up, two patients complained of frequency of stools, which settled by 6 months. To date there has been no recurrence of symptomatic diverticulosis or fistulation. CONCLUSION: Totally laparoscopic resection for diverticular fistulae is safe and feasible. Fistulae should not be considered as a contraindication to laparoscopic resection for an experienced laparoscopic surgeon.
