Traumatic Small Bowel Injury: A Diagnosis Challenge

Traumatic small bowel injury is rare complication following a blunt abdominal trauma. We encountered a case of small bowel injury following a motor vehicle accident that was initially missed during the first presentation due to unremarkable findings in examination. Patient re-presented five days later with bowel ischaemia and was managed accordingly. It is a challenge in diagnosing the injury due to its vague presentation. The usage of Focused Assessment with Sonography for Trauma (FAST) scan as a screening tool in Emergency Department to pick up intra-abdominal injury do have limitations especially in diagnosing small bowel perforation post blunt abdominal trauma. The early phase of small bowel injury post blunt abdominal trauma rarely produces significant free fluid during the FAST scan. It is paramount for the emergency doctors to have a high level of suspicion in high risk cases to provide early supportive treatment and early referral to surgical team. If left undiagnosed bowel ischaemia may lead to catastrophic complication affecting the patient’s morbidity and mortality. In conclusion, each case should be managed and risk stratify individually. Computed tomography abdomen is found to be more superior in detecting bowel injuries, hence, and investigation of choice compared to bedside ultrasonograpy in cases with high level of suspicaion.

Emergency Surgery Admissions and The COVID-19 Pandemic: Did The First Wave Really Change Our Practice? Results of An ACOI/WSES International Audit On 6263 Patients.

IntroductionThe COVID-19 pandemic is having a deep impact on emergency surgical services, with a significant reduction of patients admitted into emergency surgical units world widely. Reliable figures of this reduction have not been produced yet. Our international audit aimed at giving a precise snapshot of the absolute and relative changes of emergency surgical admissions at the outbreak of the pandemic. Materials and methodsDatasets of patients admitted as general surgical emergencies into 45 internationally distributed emergency surgical units during the months of March and April 2020 (Covid-19 pandemic outbreak) were collected and compared with those of patients admitted into the same units during the months of March and April 2019 (pre-Covid-19). Primary endpoint was to evaluate the relative variation of the presentation symptoms and discharge diagnoses between the two study periods. Secondary endpoint was to identify the possible change of therapeutic strategy during the same two periods. ResultsForty-four centres participated sent their anonymised data to the study hub, for a total of 6263 patients. Of these, 3810 were admitted in the pre-Covid period and 2453 in the Covid period, for a 35.6% absolute reduction. The most common presentation was abdominal pain, whose incidence did not change between the two periods, but in the Covid period patients presented less frequently with anal pain, hernias, anaemia and weight loss. ASA 1 and low frailty patients were admitted less frequently, while ASA>1 and frail patients showed a relative increase. The type of surgical access did not change significantly, but lap-to-open conversion rate halved between the two study periods. Discharge diagnoses of appendicitis and diverticulitis reduced significantly, while bowel ischaemia and perianal ailments had a significant relative increase.ConclusionsOur audit demonstrates a significant overall reduction of emergency surgery admissions at the outbreak of the Covid-19 pandemic with a minimal change of the proportions of single presentations, diagnoses and treatments. These findings may open the door to new ways of managing surgical emergencies without engulfing the already busy hospitals.

Is surgical exploration necessary in asymptomatic intestinal pneumatosis after lung transplantation?

Pneumatosis intestinalis is described as gas within the bowel wall and can be a sign of bowel ischaemia with a pending perforation. The described patient presented with the incidental diagnosis of pneumatosis intestinalis with free intraperitoneal gas on CT scan. His medical history included a successful lung transplantation. We here describe the clinical decision-making and evaluate our case with previous cases in the literature.

EP.TU.533A rare clinical presentation of Goblet Cell Adenocarcinoma of the appendix: Recommendations for safe & effective management

Background Goblet cell carcinoma (GCC) is a rare mixed neoplasm arising from the appendix, consisting of glandular and neuroendocrine tissue. It typically presents in adults with a mean age of 55-65 years old. Diagnosis is usually incidental via histopathological examination after 0.3% to 0.9% of all appendicectomies. Literature remains sparse on classification and prognosis of GCC, and cases documented in younger patients. Aims To highlight an interesting clinical presentation and intra- and post-operative management of GCC. To increase awareness for future practice when managing patients with GCC. Methods A 37 year-old male presented with left sided abdominal pain, constipation and fresh rectal bleeding. Computed Tomography demonstrated extensive SMV thrombus causing small bowel ischaemia. On the Intensive Care Unit, he underwent thrombolysis through a Transjugular Intrahepatic Porto-Systemic Shunt. A few days later, he developed bowel obstruction, necessitating a small bowel resection secondary to an ischaemic stricture. 9 months later, he presented with clinical signs of appendicitis. After an uneventful appendicectomy, he was diagnosed with GCC upon histopathological examination of the specimen. Results The patient made an uneventful post-operative recovery. A multidisciplinary team (MDT) decision was made to perform a completion right hemicolectomy, with histology confirming pT3N1M0 GCC. Adjuvant chemotherapy with 5-Fluorouracil was started. Conclusion This case highlights GCC with a preceding clinical course not yet published in the literature. It stresses the importance of the MDT in managing GCC. Although primarily diagnosed histologically, a clinical suspicion of GCC of the appendix is worth considering in pro-thrombotic patients.

TP9.2.7Acute Surgical Admissions at the End of Life: an Analysis of Deaths in Non-operatively Managed Patients

Aims 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 72 patients were included. 68.1% of patients 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.

A rare case of tension pneumoperitoneum secondary to gastric perforation associated with severe aortic compression

A 36-year-old male was critically unwell with acute central abdominal pain and distension. CT demonstrated severe pneumoperitoneum leading to compression and total occlusion of the inferior vena cava and occlusion of the aorta. At laparotomy a perforated posterior gastric ulcer was found with four quadrant contamination. A damage control procedure was performed and a re-look laparotomy was carried out two days later where bowel ischaemia was found. Despite being supported on the intensive care unit, unfortunately the patient died. Tension pneumoperitoneum leading to occlusion of the aorta is very rare and the severity of this condition should be recognised; it has never been survived in the reported literature. Rapid assessment and investigation is essential to ensure the timely treatment of this disease.

113 Ischaemic Bowel in The North of England: Trends in Management Approach And Patient Outcomes

Aim Bowel ischaemia is the third most common indication for emergency laparotomy in the UK and is associated with high rates of postoperative morbidity and mortality. This study describes changes in incidence, patient characteristics, management approach and outcomes for patients with bowel ischaemia over a fifteen-year period Method Data for patients admitted as an emergency, with a diagnosis of bowel ischaemia, to NHS hospitals in the North of England between 2002 and 2016 were collected. This included patient demographics and co-morbidities, operations performed and outcomes. The primary outcome of interest was in-hospital death within 30 days of admission for non-operatively managed patients and 30-day post-operative mortality for those who underwent an operative intervention. Results The incidence of bowel ischaemia has increased as a proportion of emergency general surgery admissions by 68% over fifteen years. More patients are undergoing computerised tomography (CT) imaging has (44.0% vs. 70.3%, p<0.001) and more operations are being performed within 48 hours of admission (p<0.001). The number of patients being managed operatively has fallen from 56.7% to 38.7%. Decreased 30-day mortality rates were observed for both operatively (37.5% to 26.7%, p<0.001) and non-operatively (45.7% to 26.8%, p<0.001) managed patients. Mean length of hospital stay has remained relatively unchanged over time. Conclusions Ischaemic bowel is becoming increasingly common. Increased usage of CT imaging has likely resulted in decreased rates of operative management due to its ability to accurately characterise intra-abdominal pathology. Improved mortality rates were observed for both operative and non-operative management strategies.

Small intestine leiomyosarcoma mimicking gastrointestinal stromal tumour

Small bowel malignant tumours make only 2% of all gastrointestinal (GI) malignancies. Small bowel leiomyosarcoma (LMS) is further rare, accounts for only 0.1%–3% fraction of these tumours. These cases can present as asymptomatic intra-abdominal mass, anaemia due to GI bleed or acute abdomen such as perforation peritonitis, intussusception and bowel ischaemia. Standard of care is surgical resection. Our case presented as large lobulated exophytic ileal LMS measuring 10.8×11×14.7 cm involving multiple small bowel loops and abutting right iliac vessels and uterus. Patient’s clinical course was complicated with COVID-19 positivity, deep vein thrombosis and pulmonary thromboembolism. She was managed by preoperative anticoagulation followed by resection of the tumour with end ileostomy.
