Association between troponin I levels and mortality among patients undergoing acute high-risk abdominal surgery-A cohort study.

BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is associated with 30-day mortality in heterogeneous surgical populations but is barely described after acute high-risk abdominal surgery. The impact of dynamic changes has not previously been investigated. The objectives were to determine the incidence of MINS in this population, the association between mortality and MINS, and whether plasma troponin I (TnI) dynamics have any impact on mortality. METHODS: A prospective cohort study of 341 patients undergoing acute high-risk gastrointestinal surgery was conducted. Plasma TnI was measured at the first four postoperative days. MINS was defined as any increased TnI level >59 ng/L. TnI dynamic required either two succeeding measurements of TnI >59 ng/L with a >20% increase/fall or one measurement of TnI >59 ng/L with a succeeding measurement of TnI <59 ng/L with a >50% decrease. Adjusted mortality rates were calculated using inverse probability of treatment weighting and competing risk analyses. RESULTS: The incidence of MINS was 23.8% and dynamic TnI changes occurred in 15.6% of the patients. The unadjusted 30-day and 1-year mortality were 19.8% and 35.9% in patients with MINS, compared with 2.7% and 11.6%, respectively, in patients without MINS (p < 0.001). After adjusting, the differences remained significant. There was no difference in mortality between patients with or without dynamic changes in TnI level. CONCLUSION: MINS occurred frequently and was associated with increased mortality. TnI monitoring might help identify patients with increased risk of mortality and improve care. Research on preventive measures and treatments is warranted. TRIAL REGISTRATION NUMBER AND AGENCY: ClinicalTrials.gov Identifier: NCT05933837, retrospective registered.

Long-term outcome after Bascom's pit-pick procedure for pilonidal sinus disease: A cohort study.

AIM: Previous studies have shown favourable short-term results after Bascom's pit-pick procedure for simple pilonidal sinus disease. A minimum 5-year follow-up is considered the gold standard but only a few long-term studies have previously been reported. Here, we aimed to estimate the long-term risk of treatment failure, incomplete wound healing or recurrence, postoperative complications and patient reported outcome measures such as chronic pain and satisfaction with cosmetic appearance. METHODS: Medical records of patients registered in a local database after undergoing Bascom's pit-pick procedure were reviewed and follow-up data updated. The patients received an online survey including questions about demographics, lifestyle, complications, reintervention, pain, satisfaction with cosmetic appearance and supplemented with telephone interviews if no response was received. RESULTS: A total of 158 patients underwent Bascom's pit-pick procedure during the period August 2007 to March 2014. Median follow-up was 7.98 (0.66, 10.96) years. Twelve patients (8%) had reintervention due to incomplete wound healing. A total of 32 patients experienced a recurrence. In competing risk analyses, the 10-year cumulative recurrence rate was 27% (95% CI: 19%-35%) of patients with complete wound healing. Treatment success was 68%. Recurrence was associated with active smoking, HR of 5.30 (95% CI: 1.42-19.86; p = 0.01), and number of primary pits ≥3, HR of 5.11 (95% CI: 1.49-17.47; p = 0.01). More than 90% had no postoperative complications or chronic pain, and more than 70% reported a high satisfaction with the cosmetic appearance. CONCLUSION: Bascom's pit-pick seems to be adequate treatment for most patients with a simple pilonidal sinus.
