Frequency and severity of general surgical emergencies during the COVID-19 pandemic: single-centre experience from a large metropolitan teaching hospital

INTRODUCTION

The COVID-19 pandemic has put significant stress on healthcare systems globally. This study focuses on emergency general surgery services at a major trauma centre and teaching hospital. We aimed to identify whether the number of patients and the severity of their presentation has significantly changed since the implementation of a national lockdown.

MATERIALS AND METHODS

This study is a retrospective review of acute referrals (from general practice and accident and emergency) to the emergency general surgery team over a 14-day period before (group 1) and during (group 2) lockdown.

RESULTS

A total of 151 patients were reviewed by the general surgical team in group 1 and 75 in group 2 (a 50.3% reduction). The number of days with symptoms prior to presentation was significantly shorter in group 1 compared with group 2 (3 vs 4, p = 0.04). There was no significant difference in the National Early Warning Score, white blood cell count, lymphocytes and C-reactive protein on admission between the two groups of patients. There were significantly fewer patients admitted after lockdown compared with pre-lockdown (66% vs 48%, p = 0.01). Length of hospital stay was significantly shorter during lockdown compared with pre-lockdown (5 days vs 4 days, p = 0.04).

CONCLUSION

Fewer patients were referred and admitted during lockdown compared with pre-lockdown, and the length of stay was also significantly reduced. There was also a delay in presentation to hospital, although these patients were not more unwell based on the scoring criteria used within this study.

Integrated total pelvic floor ultrasound in pelvic floor defaecatory dysfunction

AIM

Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined.

METHOD

Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated.

RESULTS

The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms.

CONCLUSION

Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

The future of pelvic floor services in the UK

AIM

The study aimed to determine the current state of UK pelvic floor services and to discuss future strategies.

METHOD

A questionnaire developed by the Pelvic Floor Society was sent in 2014 to the 175 colorectal units recognized by the Association of Coloproctology of Great Britain and Ireland. Questions included type of centre, frequency of pelvic floor clinics/interdisciplinary joint pelvic floor clinics/multidisciplinary meetings (MDMs) and workload.

RESULTS

Sixty-seven (38%) centres replied including 75% of units with a consultant who was as member of the Pelvic Floor Society. Of the 67 centres 39% were tertiary centres for pelvic floor surgery (tertiary), 48% performed some pelvic floor surgery (regional) and 13% did not perform any (local). Ninety-six per cent of tertiary referral centres served a population over 500 000. The mean number of whole time equivalent consultants in tertiary centres was 1.03 and 0.77 in regional centres. Eighty per cent of tertiary centres and 56% of regional centres ran pelvic floor clinics. Eighty-four per cent of tertiary referral and 75% of regional units held or attended an MDM. Anal ultrasonography, anorectal physiology and proctography were performed in 96% of tertiary centres compared with 50% of non-tertiary units.

CONCLUSION

The provision of pelvic floor services includes local, regional and tertiary centres. The overall response rate was low (38%) and biased to centres with a consultant who was a member of the Pelvic Floor Society. Not all regional or tertiary centres held an MDM or a pelvic floor clinic. Given the nature of pelvic floor pathology an integrated service should be aimed at linking different centres and specialities.

'23 h Model' for breast surgery: an early experience

The principles of fast track surgery are well established in colorectal surgery. It is an evidence based model aimed at reducing length of stay, convalescence and morbidity by optimising both clinical and organisational factors. Despite this, the implementation of fast track surgery in breast cancer patients has been slow. The 23 h discharge model for breast cancer surgery patients has been outlined by the NHS Improvement Programme and is a breakthrough from traditional inpatient care. This paper outlines the early experience of implementation of this model in a single institution during a 3-month audit period. Over 80% of patients undergoing non-reconstructive breast surgery were discharged safely within '23 h'. This suggests that good communication links, reorganisation of existing resources, active user involvement (both patients and clinical team) and strong project management ensures fast-tracking to be safe for the patient with significant economic benefits for the hospital.

Laparoscopic adrenalectomy for co-secreting aldosterone and cortisol adenomas

There are few published data on aldosterone and cortisol co-secreting adrenal tumours. Failure to perform comprehensive preoperative endocrine investigations in patients with adrenal "incidentalomas" or in those thought to be secreting only one hormone may account for this. Clinically patients with such lesions may have evidence of hypertension and hypokalaemia with no features of cortisol excess. Preoperative diagnosis of such lesions with accurate endocrinological work up is essential to prevent adrenal insufficiency and haemodynamic crises following removal of such glands. We present a series of 4 patients with co-secreting tumours treated by laparoscopic adrenalectomy between September 2010 and March 2011. Our experience suggests that dual secretors are more common than originally thought. A high index of suspicion and adequate endocrine work up is paramount in diagnosing such tumours and in experienced hands, laparoscopic adrenalectomy with appropriate substitutive steroid cover is safe, feasible and curative for these functioning adrenal tumours.
