Demographics, diagnostics, treatment, and outcomes of patients presenting with acute groin hernia: 15-year multicentre retrospective cohort study.

BACKGROUND: Groin hernias commonly present acutely in high-risk populations and can be challenging to manage. This retrospective, observational study aimed to report on patient demographics and outcomes, following acute admissions with a groin hernia, in relation to contemporary investigative and management practices. METHODS: Adult (≥18 years old) patients who presented acutely with a groin hernia to nine National Health Service trusts in the north of England between 2002 and 2016 were included. Data were collected regarding patient demographics, radiological investigations, and operative intervention. The primary outcome of interest was 30-day inpatient mortality rate. RESULTS: Overall, 6165 patients with acute groin hernia were included (4698 inguinal and 1467 femoral hernias). There was a male preponderance (72.5 per cent) with median age of 73 years (interquartile range (i.q.r.) 58-82). The burden of patient co-morbidity increased over the study period (P < 0.001). Operative repair was performed in 2258 (55.1 per cent) of patients with an inguinal and 1321 (90.1 per cent) of patients with a femoral hernia. Bowel resection was more commonly required for femoral hernias (14.7 per cent) than inguinal hernias (3.5 per cent, P < 0.001) and in obstructed (14.6 versus 0.2 per cent, P < 0.001) or strangulated (58.4 versus 4.5 per cent, P < 0.001) hernias. The 30-day mortality rate was 3.1 per cent for the overall cohort and 3.9 per cent for those who underwent surgery. Bowel resection was associated with increased duration of hospital stay (P < 0.001) and 30-day inpatient mortality rate (P < 0.001). Following adjustment for confounding variables, advanced age, co-morbidity, obstruction, and strangulation were all associated with an increased 30-day mortality rate (all P < 0.001). CONCLUSION: Emergency hernia repair has high mortality rates. Advanced age and co-morbidity increase both duration of hospital stay and 30-day mortality rate.

Evaluating temporal trends and the impact of surgical subspecialisation on patient outcomes following adhesional small bowel obstruction: a multicentre cohort study.

PURPOSE: Small bowel obstruction (SBO) is the most common indication for laparotomy in the UK. While general surgeons have become increasingly subspecialised in their elective practice, emergency admissions commonly remain undifferentiated. This study aimed to assess temporal trends in the management of adhesional SBO and explore the influence of subspecialisation on patient outcomes. METHODS: Data was collected for patients admitted acutely with adhesional SBO across acute NHS trusts in Northern England between 01/01/02 and 31/12/16, including demographics, co-morbidities and procedures performed. Patients were excluded if a potentially non-adhesional cause was identified and were grouped by the responsible consultant's subspecialty. The primary outcome of interest was 30-day inpatient mortality. RESULTS: Overall, 2818 patients were admitted with adhesional SBO during a 15-year period. There was a consistent female preponderance, but age and comorbidity increased significantly over time (both p < 0.001). In recent years, more patients were managed operatively with a trend away from delayed surgery also evident (2002-2006: 65.7% vs. 2012-2016: 42.7%, p < 0.001). Delayed surgery was associated with an increased mortality risk on multivariable regression analysis (OR: 2.46 (1.46-4.23, p = 0.001)). CT scanning was not associated with management strategy or timing of surgery (p = 0.369). There was an increased propensity for patients to be managed by gastrointestinal (colorectal and upper gastrointestinal) subspecialists over time. Length of stay (p < 0.001) and 30-day mortality (p < 0.001) both improved in recent years, with the best outcomes seen in colorectal (2.6%) and vascular subspecialists (2.4%). However, following adjustment for confounding variables, consultant subspecialty was not a predictor of mortality. CONCLUSION: Outcomes for patients presenting with adhesional SBO have improved despite the increasing burden of age and co-morbidity. While gastrointestinal subspecialists are increasingly responsible for their care, mortality is not influenced by consultant subspecialty.

Temporal Trends in the Investigation, Management and Outcomes of Acute Appendicitis over 15 Years in the North of England: A Retrospective Cohort Study.

BACKGROUND: Acute appendicitis is a common surgical emergency with an estimated lifetime prevalence of 8.6% for males and 6.7% for females. Despite the frequency of presentation, considerable variation in clinical practice exists. Our study aimed to explore temporal trends in the investigation, treatment and outcomes for patients with appendicitis between 2002 and 2016. METHODS: Data collected included all patients aged ≥16 years across the NHS trusts in Northern England between 01/01/2002 and 31/12/2016 diagnosed with appendicitis. Patient demographics, co-morbidity and management strategies were included. Outcomes of interest were length of stay and inpatient mortality. RESULTS: Over a 15 years period, 22,137 patients were admitted with acute appendicitis. A consistent male preponderance (n = 11,952, 54%) was observed, and median age increased over time (2002-2006: 36.4 vs. 2012-2016: 39.5, p < 0.001). Comorbidity of patients also increased (p < 0.001) in recent years. Computed tomography (CT) use increased from 0.8 to 21.9% (p < 0.001) over the study period. Following CT scanning, there was a longer time to theatre (1.22 vs. 0.70 days, p < 0.001), and patients were more frequently managed non-operatively (23.8% vs. 5.7%, p < 0.001). The utilisation of laparoscopic approaches significantly increased from 4.1 to 70.4% (p < 0.001). Laparoscopic patients had a shorter median length of stay (2.97 days) when compared with open surgery (4.44 days) or non-operative (6.19 days) patients. The 30-day mortality rate was 0.33% overall and decreased with time (p = 0.004). CONCLUSIONS: CT and laparoscopic surgery are increasingly utilised in the management of appendicitis. Along with other advances in clinical practice, they have led to reduced lengths of stay and mortality.

The impact of surgical subspecialization on patient outcomes following emergency colorectal resections in the north of England: a retrospective cohort study.

AIM: Emergency colorectal surgery is associated with significant morbidity and mortality. Most general surgeons have a subspecialty, which forms the focus of their elective work, allowing development of specialist skill sets. The aim of this study was to assess the impact of consultant subspecialization on patient outcomes following emergency colorectal resections. METHODS: Data were requested for all emergency admissions under a general surgeon between 1 January 2002 and 31 December 2016 within the north of England. These were acquired from individual Trusts following Caldicott approval. Data included demographics, diagnoses and any procedures undertaken. Patients were assigned to cohorts based on the subspecialist interest of the consultant they were under the care of. The primary outcome of interest was 30-day postoperative mortality. Categorical data were compared with the chi-squared test, and continuous data with the t test or ANOVA. A logistic regression model determined factors associated with 30-day in-hospital mortality. RESULTS: Overall, 7648 emergency colorectal resections were performed with a 30-day postoperative mortality of 13.8%. This was significantly lower if the responsible consultant was a colorectal surgeon compared with other general surgery subspecialties (11.8% vs. 15.2%, P < 0.001). This was significant on univariate analysis (OR 0.75, P < 0.001); however, following multivariable adjustment, this was not statistically significant (P = 0.380). The colorectal specialists had a higher laparoscopy rate than their colleagues-9.8% versus 6.8% (P < 0.001). Stoma rates were also lower (46.9% vs. 51.0%, P = 0.001) and anastomosis rates higher (55.9% vs. 49.3%, P < 0.001) amongst colorectal surgeons. CONCLUSION: These findings add to the growing body of evidence that patient outcomes may be improved by involving subspecialists in colorectal emergencies.

A single-centre observational cohort study to evaluate volume and severity of emergency general surgery admissions during the COVID-19 pandemic: Is there a "lockdown" effect?

INTRODUCTION: The COVID-19 pandemic has led to changes in NHS surgical service provision, including reduced elective surgical and endoscopic activity, with only essential emergency surgery being undertaken. This, combined with the government-imposed lockdown, may have impacted on patient attendance, severity of surgical disease, and outcomes. The aim of this study was to investigate a possible 'lockdown' effect on the volume and severity of surgical admissions and their outcomes. METHODS: Two separate cohorts of adult emergency general surgery inpatient admissions 30 days immediately before (February 16, 2020 to March 15, 2020), and after UK government advice (March 16, 2020 to April 15, 2020). Data were collected relating to patient characteristics, severity of disease, clinical outcomes, and compared between these groups. RESULTS: Following lockdown, a significant reduction in median daily admissions from 7 to 3 per day (p < 0.001) was observed. Post-lockdown patients were significantly older, frailer with higher inflammatory indices and rates of acute kidney injury, and also were significantly more likely to present with gastrointestinal cancer, obstruction, and perforation. Patients had significantly higher rates of Clavien-Dindo Grade ≥3 complications (p = 0.001), all cause 30-day mortality (8.5% vs. 2.9%, p = 0.028), but no significant difference was observed in operative 30-day mortality. CONCLUSION: There appears to be a "lockdown" effect on general surgical admissions with a profound impact; fewer surgical admissions, more acutely unwell surgical patients, and an increase in all cause 30-day mortality. Patients should be advised to present promptly with gastrointestinal symptoms, and this should be reinforced for future lockdowns during the pandemic.

Finegoldia magna: a rare cause of necrotising fasciitis.

Necrotising fasciitis is a life-threatening condition characterised by inflammation, affecting the soft tissues, which spreads within a fascial plane. Skin changes can be delayed and can often go unnoticed. The condition arises from a bacterial infection, commonly being of polymicrobial aetiology. We describe an uncommon case of necrotising fasciitis caused by Finegoldia magna, an anaerobic coccus, in a 40-year-old patient with diabetes. F. magna is a Gram-positive anaerobic coccus, which was previously known as Peptostreptococcus magnus The bacteria is found in the normal flora of the urogenital tract. The bacteria is associated with severe infections such as native valve endocarditis, paravalvular abscess around a bioprosthetic valve, purulent pericarditis complicated by mediastanitis, meningitis after pneumonia and necrotising pneumonia complicated by pyopneumothorax. There have been no cases in the literature describing necrotising fasciitis of the abdominal wall caused by F. magna.

Evaluating outcomes following emergency laparotomy in the North of England and the impact of the National Emergency Laparotomy Audit - A retrospective cohort study.

BACKGROUND: Emergency laparotomy is associated with high morbidity and mortality. Current trends suggest improvements have been made in recent years, with increased survival and shorter lengths of stay in hospital. The National Emergency Laparotomy Audit (NELA) has evaluated participating hospitals in England and Wales and their individual outcomes since 2013. This study aims to establish temporal trends for patients undergoing emergency laparotomy and evaluate the influence of NELA. METHODS: Data for emergency laparotomies admitted to NHS hospitals in the Northern Deanery between 2001 and 2016 were collected, including demographics, co-morbidities, diagnoses, operations undertaken and outcomes. The primary outcome of interest was in-hospital death within 30 days of admission. Cox-regression analysis was undertaken with adjustment for covariates. RESULTS: There were 2828 in-hospital deaths from 24,291 laparotomies within 30 days of admission (11.6%). Overall 30-day mortality significantly reduced during the 15-year period studied from 16.3% (2001-04), to 8.1% during 2013-16 (p < 0.001). After multivariate adjustment, laparotomies undertaken in more recent years were associated with a lower mortality risk compared to earlier years (2013-16: HR 0.73, p < 0.001). There was a significant improvement in 30-day postoperative mortality year-on-year during the NELA period (from 9.1 to 7.1%, p = 0.039). However, there was no difference in postoperative mortality for patients who underwent laparotomy during NELA (2013-16) compared with the preceding three years (both 8.1%, p = 0.526). DISCUSSION: 30 day postoperative mortality for emergency laparotomy has improved over the past 15-years, with significantly reduced mortality risk in recent years. However, it is unclear if NELA has yet had a measurable effect on 30-day post-operative mortality.

An evaluation of the epidemiology, management and outcomes for perforated peptic ulcers across the North of England over 15 years: A retrospective cohort study.

BACKGROUND: The management of perforated peptic ulcers has evolved over time and includes laparoscopic or open repair, and conservative management. The utilisation of, and outcomes from these strategies are not clear. Trends in epidemiology, management and outcomes for perforated peptic ulcer across the North of England over a 15-year period were analyzed. PATIENTS AND METHODS: Emergency General Surgical admissions data from nine NHS trusts in the North of England from 2002 to 2016 were collected and analyzed, including demographics, interventions and outcomes. Cases were identified using ICD-10 codes K25, K26 and K27 0.1, 0.2, 0.5, 0.6. RESULTS: Peptic ulcer perforation accounted for 2373 of 491141 admissions (0.48%), with a decreased incidence over time (0.62% in 2002-2006 to 0.36% in 2012-2016). Over the 15 years studied, an increasing proportion of cases were managed laparoscopically (4.5%-18.4%, p < 0.001) and under upper-gastrointestinal consultants (15.4%-28.6%, p < 0.001). Thirty-day inpatient mortality improved significantly over time (20.0%-10.8%, p < 0.001) as did mean length of stay (17.3-13.0 days, p = 0.001). Independent predictors of increased 30-day mortality were increasing age, Charlson co-morbidity score, clinical and operative risk, earlier year of admission, winter admission, weekend/bank holiday procedure and management strategy, with laparotomy and conservative management increasing risk. CONCLUSION: Outcomes (30-day mortality and LOS) improved significantly over the study period. Laparoscopic approach was increasingly utilised and was an independently significant factor associated with improved mortality. Management by upper-gastrointestinal specialists increased rates of laparoscopy, with fewer conversions to open.

Evaluating the effects of surgical subspecialisation on patient outcomes following emergency laparotomy: A retrospective cohort study.

BACKGROUND: General surgeons have become increasingly subspecialised in their elective practice. Emergency laparotomies, however, are performed by a range of subspecialists who may or may not have an interest in the affected area of gastrointestinal tract. This retrospective cohort study evaluates the impact of surgical subspecialisation on patient outcomes following emergency laparotomy. METHODS: Data was collected for patients who underwent an emergency abdominal procedure on the gastrointestinal tract in the North of England from 2001 to 2016. This included demographics, co-morbidities, diagnoses and procedures undertaken. Patients were grouped according to consultants' subspecialist interest. The primary outcome of interest was 30-day postoperative mortality. RESULTS: 24,291 emergency laparotomies were performed with an associated 30-day postoperative mortality of 11.7%. Laparotomies undertaken by upper gastrointestinal (UGI) or colorectal surgeons have significantly lower mortality (10.1%) when compared with other subspecialities (13.5%). More specifically, mortality was decreased for UGI (7.9% vs. 12.9%) and colorectal procedures (10.9% vs. 14.2%) when performed by surgeons with a specialist interest in the relevant area of the gastrointestinal tract (both p < 0.001). The utilisation of laparoscopic surgery is higher, in both UGI (21.8% vs. 9.0%) and colorectal procedures (7.2% vs. 3.5%), when the causative pathology is relevant to the surgeon's subspeciality (both p < 0.001). CONCLUSION: Mortality following emergency laparotomy is improved when performed under the care of gastrointestinal surgeons. Both UGI and colorectal emergency procedures have improved outcomes, with lower mortality and higher rates of laparoscopy, when under the care of a surgeon with a subspecialist interest in the affected area of the gastrointestinal tract.

A 15-year retrospective analysis of the epidemiology and outcomes for elderly emergency general surgical admissions in the North East of England: A case for multidisciplinary geriatric input.

INTRODUCTION: Life expectancies in the UK are increasing and with this there is an increasing elderly population with more complex co-morbidity. Emergency surgery in the elderly is challenging in terms of decision making, managing co-morbidity and post-operative rehabilitation with high morbidity and mortality. To optimise service design and development, it is important to understand the changing pattern of emergency surgical care for this group. METHODS: After obtaining necessary approvals, we approached each hospital trust in the North of England for details of every emergency admission under a general surgeon from 2000 to 2014. Data for each admission included demographics, co-morbidities, diagnoses, procedures undertaken and outcomes. RESULTS: There were 105 002 elderly (≥70 years) emergency general surgical admissions, and mean age and co-morbidity (defined by Charlson index scores) increased (both p < 0.001). Operative intervention was undertaken in a similar proportion of patients in all age groups (13%), with more patients undergoing operations over time (p < 0.001), of which 50% were within 48 h of admission. Overall in-hospital mortality decreased significantly as did length of hospital stay (both p < 0.001). Factors associated with increased 30 day in-hospital mortality were increasing age and Charlson score, admissions directly from clinic, operations undertaken at the weekend and patients admitted earlier in the study period. CONCLUSION: The workload of emergency general surgery in the elderly is becoming more complex. This challenge is already being addressed with improvements in outcomes. The data presented here reinforces the need for new models of care with increased multidisciplinary geriatric care input into elderly surgical patient care in the perioperative period.

Perioperative and long-term outcomes following aortic valve replacement: a population cohort study of 4124 consecutive patients.

OBJECTIVE: Because of increasing life expectancy, more patients require valve replacement for aortic stenosis. We aimed to determine perioperative and long-term outcomes, the factors associated with these and whether they have changed over time. METHODS: We undertook a retrospective cohort study of all 4124 patients, who underwent isolated, primary aortic valve replacement in Scotland between April 1996 and March 2009 inclusive. RESULTS: Annual operations increased by 68%, from 261 to 439. The overall risk of dying within 30 days, 5 years and 10 years was 3.4%, 19.9% and 38.5%, respectively. Over 10 years' follow-up, 4.4% underwent further valve surgery, 7.9% suffered a stroke and 5.3% a myocardial infarction. Age, renal impairment and urgency were predictors of both perioperative and long-term death. Perioperative death was associated with left-ventricular impairment and long-term death with respiratory disease, diabetes and deprivation. Over the 13 years, there was an increase in median age (from 66 to 69 years, p < 0.001), diabetes (from 1.9% to 12.6%, p < 0.001), hypertension (from 26.4% to 56.1%, p < 0.001), cerebrovascular disease (from 3.7% to 9.8%, p < 0.001), respiratory disease (from 6.6% to 9.7%, p = 0.020) and previous myocardial infarction (from 0.6% to 5.8%, p < 0.001), but the risk of perioperative death fell from 6.5% to 3.1% (odds ratio (OR) 0.87, 95% confidence interval (CI) 0.83, 0.92, p < 0.001) per year. CONCLUSIONS: Patients undergoing aortic valve replacement have a poor risk profile. Over time, their numbers, age and co-morbidity have increased. In spite of these, there has been a significant reduction in the risk of perioperative death.
