Is pelvic ultrasound useful in the clinical assessment and management of women with right iliac fossa pain? A single-centre retrospective study

INTRODUCTION

Acute right iliac fossa (RIF) pain is a common presenting symptom in surgical patients, with a wide range of differentials, particularly in premenopausal females. This study explores ultrasound usage in the management of women aged 16-55 years presenting with RIF pain.

METHODS

A total of 1,082 patients who presented to a tertiary hospital over 12 months were included. Data were collected from patients' electronic records, including initial clinical impression, imaging, management, operative findings, histology and subsequent hospital attendances within 6 weeks and within 6 months.

RESULTS

Following clinical assessment, 607 (56%) of patients underwent an ultrasound. Of these, 280 (25.9%) patients received no radiological imaging on initial presentation, and 252 (42%) had pathology identified on ultrasound. The most common finding was an ovarian cyst, closely followed by unexplained free pelvic fluid. Of the 607 patients scanned, 29 (4.8%) had an ultrasound diagnosis of appendicitis; 254 of 1,082 (23.5%) patients underwent operative management. Of the 254 patients who had surgery, 179 (70.5%) had preoperative imaging. Of the 29 (11.4%) cases where the intraoperative finding was gynaecological, 15 (51.7%) cases had not had any preoperative imaging. The negative appendicectomy rate was 21.3% (45/211). Of the 45 patients who had a histologically normal appendix, 22 (48.9%) had not had any previous imaging. Ultrasound had a specificity of 78% for diagnosing appendicitis.

CONCLUSIONS

In patients who underwent operative management, a negative finding or finding not requiring surgical management was associated with no preoperative imaging. This supports the use of ultrasound scans as an adjunct in a multimodal approach to the assessment of women presenting with RIF pain.

Defining core patient descriptors for perforated peptic ulcer research: international Delphi

BACKGROUND

Perforated peptic ulcer (PPU) remains a common condition globally with significant morbidity and mortality. Previous work has demonstrated variation in reporting of patient characteristics in PPU studies, making comparison of studies and outcomes difficult. The aim of this study was to standardize the reporting of patient characteristics, by creating a core descriptor set (CDS) of important descriptors that should be consistently reported in PPU research.

METHODS

Candidate descriptors were identified through systematic review and stakeholder proposals. An international Delphi exercise involving three survey rounds was undertaken to obtain consensus on key patient characteristics for future research. Participants rated items on a scale of 1-9 with respect to their importance. Items meeting a predetermined threshold (rated 7-9 by over 70 per cent of stakeholders) were included in the final set and ratified at a consensus meeting. Feedback was provided between rounds to allow refinement of ratings.

RESULTS

Some 116 clinicians were recruited from 29 countries. A total of 63 descriptors were longlisted from the literature, and 27 were proposed by stakeholders. After three survey rounds and a consensus meeting, 27 descriptors were included in the CDS. These covered demographic variables and co-morbidities, risk factors for PPU, presentation and pathway factors, need for organ support, biochemical parameters, prognostic tools, perforation details, and surgical history.

CONCLUSION

This study defines the core descriptive items for PPU research, which will allow more robust synthesis of studies.

658 Managing the Acute Surgical Patient – How has COVID-19 Changed Our Approach?

Aim

COVID-19 has changed how surgical admissions are triaged and treated. This retrospective cohort study aims to detail the effects of a national lockdown on emergency general surgical referrals at a tertiary centre.

Method

A retrospective search identified all emergency general surgery referrals prior to and during the UK national lockdown. Pre (10-23 Feb 2020;PLG) and intra-lockdown (30 Mar-12 Apr 2020;ILG) groups were compared using descriptive statistics and significance was quantified with Chi-squared.

Results

600 patients were included of which 426 (71%) presented in the PLG. The PLG had proportionally fewer ED referrals (40.8%vs.51.1%, p = 0.02) and less cross-sectional imaging performed (31.5%vs.40.8%, p = 0.03). There was a significant reduction in non-specific abdominal pain (NSAP) during lockdown (25.12%vs.14.94%, p = 0.007). GP referrals (48.8%vs.46.6%, p = 0.61), admission (46.2%vs.44.8%, p = 0.09) and operative intervention (21.4% vs.17.24%, p = 0.25) showed no disparity.

Conclusions

Predictably, the advent of lockdown resulted in a reduction in hospital attendance and surgical referrals. Our data showed a similar proportion of referred patients admitted pre- and intra-lockdown despite a reduction in absolute terms. This may be due to a trend towards later presentation coupled with a focus on conservative management and prevention of admission. The decrease in NSAP raises questions that require further exploration. Cross-sectional imaging was used more freely as an adjunct in the ILG suggesting increasing acuity and delayed presentation or may result from a tendency towards image-guided discharge. Admissions have since trended towards pre-lockdown levels, but it is yet to be seen if a reduction in elective operating will lead to an increase in emergency admissions.

Case-based review: conservative management of appendicitis--are we delaying the inevitable?

Acute appendicitis is a common surgical presentation for which surgical intervention, an appendicectomy, has remained a largely unchallenged primary treatment modality. Traditionally, it has been felt that the pathophysiological progressive nature of appendicitis ultimately leads to perforation. A number of recent studies, however, suggest that the process of appendiceal inflammation may follow a more remitting nature with evidence indicating spontaneous resolution. It is hypothesised that the treatment of uncomplicated appendicitis may therefore be amenable to conservative management with antibiotics. This article aims to highlight some of the issues and challenges relating to the conservative management of acute appendicitis and further demonstrates potential diagnostic and treatment difficulties involved in managing the more unfamiliar condition of recurrent appendicitis.

Small bowel perforation secondary to accidental dental plate ingestion

The majority of ingested foreign bodies will pass through the gastrointestinal tract without incident, with less than 1% of cases resulting in complications. Herein we present a case of small bowel perforation secondary to the accidental ingestion of a dental plate. A diagnosis of perforation was made by CT imaging, but the exact cause could only be determined after resection of the affected bowel and histo-pathological examination. We re-iterate the importance of accurate and thorough history taking in patients with possible foreign body ingestion.
