Impact of surgeon volume on 18-month unclosed ileostomy rate after restorative rectal cancer resection.

AIM: The impact of surgeon volume on 18-month unclosed ileostomy rates after rectal cancer surgery has not been fully explored. The aim of this study was to describe the effect of surgeon volume and evaluate factors predictive of an unclosed ileostomy. METHOD: Patients undergoing anterior resection with a diverting ileostomy for rectal cancer from March 2004 to October 2018 were identified from a prospectively maintained database. The unclosed ileostomy rate was determined by those with an unclosed ileostomy at 18 months. High- and low-volume surgeons (HVS and LVS, respectively) were classed as those performing five or more or fewer than five rectal cancer resections per year, respectively. Data on sex, age, American Society of Anesthesiologists grade, neoadjuvant chemoradiotherapy (CRT), tumour height, T-stage, anastomotic leak, surgical approach and adjuvant chemotherapy were also collected. Factors predictive of an unclosed ileostomy at 18 months were explored using a multivariate binary logistic regression analysis. RESULTS: A total of 415 patients (62.4% male) with a median age of 67 were eligible for analysis. Of these, 115 (27.7%) had an unclosed ileostomy at 18 months. HVS had an unclosed ileostomy rate of 24.6% (72/292) compared with 34.9% (43/123) for LVS. Volume was associated with an unclosed ileostomy in univariable analysis (p = 0.032) but not in multivariate analysis (OR 1.75, 95% CI 0.92-3.32, p = 0.08). Independent factors predictive of an unclosed ileostomy were anastomotic leak (OR 10.41, 3.95-27.0, p < 0.01), adjuvant chemotherapy (OR 2.23, 1.24-3.96, p < 0.01) and neoadjuvant CRT (OR 2.16, 1.15-5.75, p = 0.01). CONCLUSION: LVS were associated with a higher unclosed ileostomy at 18 months compared with HVS. This study adds further weight to the call for adoption of a minimum annual case threshold in rectal cancer surgery.

Effects of ethnicity and socioeconomic status on surgical outcomes from inflammatory bowel disease.

PURPOSE: Evidence suggests that ethnicity and socioeconomic status of patients with chronic diseases influence their healthcare outcomes. The aim of this study was to assess the impact of these factors on the surgical outcome of patients with inflammatory bowel disease (IBD) over a 15-year period. METHODS: A retrospective observational study investigated IBD patients operated on at an NHS Trust between 2000-2015, with follow-up data until 2020. Logistic regression models were used to determine the relationship between ethnic minority background and Index of Multiple Deprivation (IMD) on outcomes including requirement for intra-abdominal surgery, permanent stoma, re-do surgery and surgical complications, accounting for age, gender, smoking history and biologic treatment. RESULTS: There were 1,620 patients (56.7% ulcerative colitis (UC) and 43.3% Crohn's disease (CD)). Median age was 32 years, and 49.6% were female. Patients with an ethnic minority background accounted for 20.6%. Within 5 years of first presentation, 369 patients required intra-abdominal surgery, 95 permanent stomas and 107 re-do surgery. For CD patients, younger age at diagnosis, female patients, those with an ethnic minority background, higher IMD quintile, smoking history and biologic treatment were more likely to have intra-abdominal surgery. Ethnic minority background and higher IMD score were further associated with surgical complications for CD but not UC patients. CONCLUSION: Ethnic minority status and socioeconomic deprivation were associated with worse surgical outcomes within our cohort of IBD patients. These findings may stimulate discourse regarding the strategic planning of equitable healthcare services.

Late endovascular coil migration following traumatic pulmonary artery pseudoaneurysm embolization: case report.

BACKGROUND: Percutaneous vascular interventions are performed for the treatment of haemoptysis and involve embolization of bronchial arteries, pulmonary arteries and pulmonary arteriovenous malformations. There are isolated reports of embolization of pseudoaneurysms forming in the pulmonary vasculature. The migration of components of the coils used in the embolization of vascular pulmonary pathologies is rare. CASE PRESENTATION: A 46-year-old man presented to the emergency department with cough, haemoptysis, and expectoration of lengths of metal wire. He had an episode of coughing out a wire about a year prior to his admission to our hospital, which he attributed to be present in the can of coke he had consumed at that time and did not report it to the doctors. His past medical history was significant for stab injury to the right chest 17 years ago, for which he underwent right thoracotomy and exploration for bleeding. Injury to the lung parenchyma was noted and repair was performed by suturing the defect. Post operatively the CT scan demonstrated development of pulmonary artery pseudoaneurysm. We report a case of a patient expectorating coils 17 years after embolization of this traumatic pulmonary artery pseudoaneurysm. Radiological imaging demonstrated coils in the perihilar area of the lung parenchyma and in the tracheobronchial lumen. Operative intervention was used to remove the coils. CONCLUSIONS: Although percutaneous catheter based vascular interventions have emerged as safe and effective procedures, the long-term complications such as coil migration, recanalization and need for further embolization ought to be considered and patients need to be counselled and followed-up accordingly. To the best of our knowledge, this is the first case of migrated coil post embolization of post-traumatic pulmonary artery pseudoaneurysm. Ultimately, the management of endobronchial coil migration post embolization, be it surgical or bronchoscopic, should be decided on a case-by-case basis, considering the patient's symptoms and the risk fatal complications.
