Thoracic irrigation for prevention of secondary intervention after thoracostomy tube drainage for hemothorax: A Western Trauma Association multi-center study.

BACKGROUND: Retained hemothorax (rHTX) requiring intervention occurs in up to 20% of patients who undergo chest tube (TT) placement for a hemothorax (HTX). Thoracic irrigation at the time of TT placement decreases the need for secondary intervention in this patient group but those findings are limited because of the single center design. A multi-center study was conducted to evaluate the effectiveness of thoracic irrigation. METHODS: A multi-center, prospective, observational study was conducted between June 2018 and July 2023. Eleven sites contributed patients. Patients were included if they had a TT placed for a HTX and were excluded if: age < 18 years, TT for pneumothorax, thoracotomy or VATS performed within 6 hours of TT, TT >24 hours after injury, TT removed <24 hours, or death within 48 hours. Thoracic irrigation was performed at the discretion of the attending. Each hemithorax was considered separately if bilateral HTX. The primary outcome was secondary intervention for HTX-related complications (rHTX, effusion, or empyema). Secondary intervention was defined as: TT placement, instillation of thrombolytics, VATS, or thoracotomy. Irrigated and non-irrigated hemithoraces were compared using a propensity weighted analysis with age, sex, mechanism of injury, Abbreviated Injury Scale (AIS) chest and TT size as predictors. RESULTS: 493 patients with 462 treated hemothoraces were included, 123 (25%) had thoracic irrigation at TT placement. There were no significant demographic differences between the cohorts. Fifty-seven secondary interventions were performed, 10 (8%) and 47 (13%) in the irrigated and non-irrigated groups, respectively (p = 0.015). Propensity weighted analysis demonstrated a reduction in secondary interventions in the irrigated cohort (Odds Ratio 0.56 (0.34-0.85); p = 0.005). CONCLUSION: This Western Trauma Association multi-center study demonstrates a benefit of thoracic irrigation at the time of TT placement for a HTX. Thoracic irrigation reduces the odds of a secondary intervention for rHTX-related complications by 44%. LEVEL OF EVIDENCE: Therapeutic Study, Level II.

Emergent embolization of the gastroduodenal artery in the treatment of upper gastrointestinal bleeding. The experience from a surgeon-initiated interventional program.

BACKGROUND: Intractable nonvariceal upper gastrointestinal bleeding (UGIB) is associated with significant morbidity and mortality. Endovascular therapy is an alternative to surgery for high-risk patients. MATERIALS AND METHODS: Review of prospectively collected data from patients who underwent emergent gastroduodenal artery embolization for UGIB. RESULTS: Eight patients (mean age 68.5 years) were identified. They all had significant comorbidities and were deemed to be at high risk for surgical intervention. Endoscopy was performed in 7 patients. Active extravasation was present at the time of embolization in 5 (62.5%) patients. The technical success and clinical response rates were each 100%. The 30-day mortality rate was 12.5%. [corrected] There were no procedure-related complications. During mean follow-up of 9 months, 1 patient developed recurrent bleeding that was managed conservatively. COMMENTS: Endovascular embolization is a safe alternative to open surgical intervention after failed endoscopic treatment for UGIB. Surgeons with endovascular skills can perform this procedure with superior results.
