    Objective: After congenital heart surgery, some patients may need long-term mechanical ventilation because of chronic respiratory failure. In this study, we analysed outcomes of the patients who need tracheostomy and home mechanical ventilation. Methods: Amongst 1343 patients who underwent congenital heart surgery between January, 2014 and June, 2018, 45 needed tracheostomy and HMV. The median age of these patients was 6.4 months (12 days-6.5 years). Nineteen patients underwent palliation while 26 patients underwent total repair. Post-operative diaphragm plication was performed in five patients (11\%). Median duration of mechanical ventilation before tracheostomy was 32 days (8-154 days). The patients were followed up with their home ventilators in ward and at home. Mean follow-up time was 36.24 +/- 11.61 months. Results: The median duration of ICU stay after tracheostomy was 27 days (range 2-93 days). Follow-up time in ward was median 30 days (2-156 days). A total of 12 patients (26.6\%) were separated from the ventilator and underwent decannulation during hospital stay. Thirty-two patients (71.1\%) were discharged home with home ventilator support. Of them, 15 patients (46.9\%) were separated from the respiratory support in median of 6 weeks (1 week-11 months) and decannulations were performed. Total mortality was 31.1\%. in which four patients are still HMV dependent. There was no significant difference for decannulation between total repair and palliation patients. Conclusion: HMV via tracheostomy is a useful option for the treatment of children who are dependent on long-term ventilation after congenital heart surgery although there are potential risks.

    Utility of Cervical Cannulation During Difficult Resternotomy in Congenital Heart Surgery
    (SAGE PUBLICATIONS INC, 2020-01-01) Temur, Bahar; Davutoglu, Arda; Dogruoz, Alper; Aydin, Selim; Suzan, Dilek; Kirat, Baris; Odemis, Ender; Erek, Ersin
    Background: Adhesions due to previous surgeries and some anatomical difficulties may make resternotomy dangerous in children. Femoral vessels are usually small and may not be suitable for cannulation. The aim of this report is to describe our experience with cervical cannulation during risky resternotomy in children. Methods: Between January 2014 and January 2018, cervical cannulation was performed in eight pediatric patients during sternal reentry. Their ages were between 3 months and 17 years (mean: 5.4 years). Three patients underwent stage III extracardiac Fontan operation with the diagnosis of hypoplastic left heart syndrome. Three patients had supravalvular aortic and/or pulmonary stenosis after previous arterial switch operation. One patient had proximal aortic arch stenosis and subvalvular aortic stenosis after interrupted aortic arch repair. The last patient had aortic root pseudoaneurysm and aortic insufficiency due to endocarditis. Through a separate cervical incision, a polytetrafluoroethylene graft was anastomosed to the common carotid artery and the arterial cannula was inserted into the graft. Antegrade selective cerebral perfusion (ASCP) was used in two patients. Results: During resternotomies, no major injury or bleeding occurred. Three-month-old patient who had previous interrupted aortic arch repair died despite extracorporeal membrane oxygenation support due to sepsis and multi-organ failure. Median intensive care unit stay and hospital stay were 3 days (1-40 days) and 17 days (7-60 days), respectively. Mean follow-up was 17.9 +/- 15.8 months. All patients were in good clinical condition. Conclusions: Cervical cannulation may be a useful and safe technique during high-risk resternotomy in children. This technique may also simplify the performance of ASCP if necessary.

    Robotic Rectal Cancer Surgery with the da Vinci Xi System: First 100 Cases
    (ISTANBUL TRAINING \& RESEARCH HOSPITAL, 2019-01-01) Ozben, Volkan; Dogruoz, Alper; Boga, Salih Anil; Aytac, Erman; Baca, Bilgi; Hamzaoglu, Ismail; Karahasanoglu, Tayfun
    Introduction: The da Vinci Xi system, the latest model of the robotic technology, is proposed to enable multiquadrant abdominal surgery to be performed in a fully robotic approach without the need for a laparoscopic assistance, robot re-docking or re-positioning of the trocars. However, the literature has limited data on this topic. In this study, we aimed to evaluate the feasibility of the Xi robot use in rectal cancer surgery, a multiquadrant surgical procedure. Methods: Patients undergoing robotic mezorectal excision for rectal adenocarcinoma using the da Vinci Xi system between December 2014 and June 2017 were included in this study. Data were collected prospectively and analyzed retrospectively. Demographic data, perioperative clinical findings, histopathologic data and postoperative 30-day outcomes were analyzed. Results: One hundred patients were included in this study. There were 57 male and 43 female patients with a mean age of 61.4 +/- 12.3 years. Low anterior resection and abdominoperineal recetion were performed in 90 and 10 patients, respectively. In all the operations, the abdominal and pelvic stages of the procedure were completed robotically without a need for dual docking or trocar re-positioning. The mean operative time was 328.4 +/- 105.8 min and blood loss was 131.7 +/- 170.3 mL. Intraoperative complication occurred in 2 patients (2\%). Two procedures were converted to open surgery (2\%). The mean number of harvested lymph nodes was 25.3 +/- 12.0. All the surgical margins were clear except for four patients (4\%). The rate of incomplete mesorectal fascia was 3.2\%. The mean length of hospital stay was 6.6 +/- 3.6 days and the overall postoperative morbidity rate was 25\%. Conclusion: The da Vinci Xi model enables rectal cancer operations to be performed in a fully robotic fashion. This feature of the robot helps surgeon to benefit optimally from the advantages robotic surgery in all stages of the procedure.
