BackgroundThe number of colonoscopic procedures continues to rise rapidly. With widespread adoption of colonoscopy based bowel screening programmes, this rising trend is set to continue.AimsThis study aimed to identify whether elective colonoscopy could provoke cardiac rhythm disturbances and/or myocardial ischaemia, as evidenced by 12 lead Holter ECG recordings and troponin I (cTnI) changes.Materials and methodsPatients were stratified into three groups based on the presence of cardiac disease or cardiovascular risk factors. They underwent real time 12 lead Holter monitoring before, during and after colonoscopy. Bloods were taken for pre- and post-procedure cTnI estimation.ResultsHolter ECG recordings of the three groups showed a high incidence of new but silent ischaemic and arrhythmic ECG changes during the colonoscopy in patients with documented but stable heart disease and to a lesser extent in those patients with one or more risk factors for heart disease. Three patients had high cTnI concentrations both before and after colonoscopy. Two patients with known heart disease died within 30 days of colonoscopy.ConclusionsThis study demonstrates for the first time the occurrence of potentially clinically significant ST-T wave changes and rhythm disturbances during elective colonoscopy in patients with known heart disease and to a lesser extent in those patients with a known cardiovascular risk profile.

Introduction The aim of this study was to study radiological assessment, management and outcome of traumatic splenic injury over 15 years in a UK district general hospital. Method A retrospective database was established including all splenic injury cases from June 2002 to June 2017 by searching the clinical electronic database. We searched the radiological database for computed tomography reported phrases ‘spleen injury’, ‘laceration’, ‘haematoma’, ‘trauma’. We interrogated theatre records for operations coded as splenectomy and cross-referenced this with pathology. Records were reviewed for demographics, vital observations, documentation of American Association for the Surgery of Trauma (AAST) grading of splenic injury, subsequent management and outcomes. Results There were 126 patients identified with traumatic splenic injury, with male to female ratio three to one. Operative management was undertaken in 54/126 (43%) patients and selective non-operative management in the remaining. Splenic artery embolisation was undertaken in 5/126 (4%) and 2/126 underwent splenorrhaphy. Computed tomography was undertaken in 109/126 (87%) patients and AAST grading was reported in 18 (17%) patients. AAST grade reporting did not improve significantly when comparing the first 7.5 years with the latter (2/30, 7%; 16/79, 20%), respectively; p = 0.09). Selective non-operative management increased significantly over the studied period (14/34, 42%; 58/93, 62%; p = 0.04). The overall hospital mortality was 10.3%. Discussion and conclusion AAST grade reporting of splenic injury has remained sub-optimal over 15 years. Despite progression towards selective non-operative management, operative intervention remained unacceptably high, with splenectomy being the main therapeutic modality. Standardisation through an integrated multidisciplinary diagnostic and management pathway offers the optimal strategy to reduce trauma-induced splenectomy.
