Surgical Repair of a Traumatic Tracheobronchial Injury in a Pediatric Patient Assisted with Venoarterial Extracorporeal Membrane Oxygenation.

Tracheobronchial rupture due to blunt chest trauma is a rare but life-threatening injury in the pediatric population. Computed tomography (CT) is not always reliable in the management of these patients. An additional concern is that ventilation may be disrupted during surgical repair of these injuries. This report presents the case of a 4 -year-old boy with an injury to the lower trachea and carina due to blunt force trauma that was missed on the initial CT scan. During surgery, he was administered venoarterial extracorporeal membrane oxygenation (ECMO). Although ECMO is not generally used in children, this case demonstrated that the short-term use of ECMO during pediatric surgery is safe and can prevent intraoperative desaturation.

Feasibility of four-arm robotic lobectomy as solo surgery in patients with clinical stage I lung cancer.

BACKGROUND: This study was performed to investigate the feasibility of four-arm robotic lobectomy (FARL) as a solo surgical technique in patients with non-small cell lung cancer (NSCLC). Early outcome and long-term survival of FARL were compared with those of video-assisted thoracoscopic lobectomy (VATL). METHODS: Prospective enrollment of patients with clinical stage I NSCLC undergoing FARL or VATL (20 patients in each group) was planned. Interim analysis for early postoperative outcome was performed after the initial 10 cases in each group. RESULTS: The study was terminated early because of safety issues in the FARL group after enrollment of 12 FARL and 17 VATL patients from 2011 to 2012. There were no differences in clinical characteristics between groups. Lobectomy time and total operation time were significantly longer in the FARL group (P=0.003). There were three life-threatening events in the FARL group (2 bleedings, 1 bronchus tear) that necessitated thoracotomy conversion in 1 patient. There were no differences in other operative outcomes including pain score, complications, or length of hospital stay. Pathologic stage and number of dissected lymph nodes (LNs) were also comparable. During a follow-up of 48.9±9.5 months, recurrence was identified in 2 (16.7%) patients in FARL group and 3 (23.5%) in VATL group. Five-year overall survival (100% vs. 87.5%, P=0.386) and disease-free survival (82.5% vs. 75.6%, P=0.589) were comparable. CONCLUSIONS: FARL as solo surgery could not be recommended because of safety issues. It required a longer operation time and had no benefits over VATL in terms of early postoperative outcome or long-term survival.

Early and Long-term Outcomes of Pneumonectomy for Treating Sequelae of Pulmonary Tuberculosis.

BACKGROUND: Pneumonectomy remains the ultimate curative treatment modality for destroyed lung caused by tuberculosis despite multiple risks involved in the procedure. We retrospectively evaluated patients who underwent pneumonectomy for treatment of sequelae of pulmonary tuberculosis to determine the risk factors of early and long-term outcomes. MATERIALS AND METHODS: Between January 1980 and December 2008, pneumonectomy or pleuropneumonectomy was performed in 73 consecutive patients with destroyed lung caused by tuberculosis. There were 48 patients with empyema (12 with bronchopleural fistula [BPF]), 11 with aspergilloma and 7 with multidrug resistant tuberculosis. RESULTS: There were 5 operative mortalities (6.8%). One patient had intraoperative uncontrolled arrhythmia, one had a postoperative cardiac arrest, and three had postoperative respiratory failure. A total of 29 patients (39.7%) suffered from postoperative complications. Twelve patients (16.7%) were found to have postpneumonectomy empyema (PPE), 4 patients had wound infections (5.6%), and 7 patients required re-exploration due to postoperative bleeding (9.7%). The prevalence of PPE increased in patients with preoperative empyema (p=0.019). There were five patients with postoperative BPF, four of which occurred in right-side operation. The only risk factor for BPF was the right-side operation (p=0.023). The 5- and 10-year survival rates were 88.9% and 76.2%, respectively. The risk factors for late deaths were old age (≥50 years, p=0.02) and low predicted postoperative forced expiratory volume in one second (FEV1) (<1.2 L, p=0.02). CONCLUSION: Although PPE increases in patients with preoperative empyema and postoperative BPF increases in right-side operation, the mortality rates and long-term survival rates were found to be satisfactory. However, the follow-up care for patients with low predicted postoperative FEV1 should continue for prevention and early detection of pulmonary complication related to impaired pulmonary function.
