ObjectiveTo summarize the clinical application of the minimally invasive step-up approach in the treatment of severe acute pancreatitis (SAP), and to explore the clinical indications, timing for the minimally invasive step-up approach, and to make comparison with open necrosectomy.
MethodsThe literatures about the treatment of SAP in recent years were collected to make a review.
ResultsThe minimally invasive step-up approach, comparing with open necrosectomy, was more effective to treat SAP, however, itself had its own limitations. In the treatment process, the optimal method was minimally invasive step-up approach, but also did not exclude open necrosectomy.
ConclusionsThe treatment of SAP can not rely on a single method, it needs a comprehensive treatment which is relate with multidisciplinary management and highly individual choice. In addition, it needs further study to explore the timing and indications for transforming minimally invasive step-up approach into open necrosectomy.
Objective To review our experience of minimally invasive direct coronary artery bypass grafting （MIDCAB） via a lower median ministernotomy in 72 cases. Methods Via a lower median ministernotomy,the left internal mammary artery was harvested to bypass the left anterior descending coronary artery. Saphenous vein was resected and used for single - or multi-vessel coronary revascularization on the beating heart. Results There were 1 operative death （1.4 % ）. Complications occurred in 3 patients （4.2%）. The operative duration was 195.6 ± 50. 6 min. The number of distal anastomoses was 2.3±0. 8（1-4）. The median time to tracheal extubation, and lengths of postoperative ICU and hospital stays were 11 hours, 3 and 9 days, respectively. Total chest drainage was 8. 54±5.9 ml/kg and 47 patients needed blood transfusion with an amount of 1 091.3±636.2 ml. The incision on the chest wall was 9 to 11 cm long in all cases. Sixty-six patients （92.9%, 66/71） were followed-up for a duration of 36.2±17.6 months. There were no late death and 43 patients （65.2%） were free from angina. Eighteen patients （27.3%, 18/ 66） experienced marked relief of their symptoms. Conclusions MIDCAB is possible via a lower ministernotomy for single - or multi-vessel coronary revascularization. The small incision reduces the risk of infection and blood loss. It is safe, easy and requires no special operative instruments.
Abstract： Objective To explore a new videoassisted thoracoscopic surgical treatment for lone atrial fibrillation, in order to seek better efficacy, reduce invasiveness, and devise an easiertooperate surgical treatment for atrial fibrillation. Methods In June 2011, 3 women aged 40 years, 60 years, and 66 years with lone atrial fibrillation were treated in the Cardiovascular Surgery Department of West China Hospital. The patients underwent a videoassisted thoracoscopic “Box Lesion” bipolar radiofrequency atrial fibrillation therapy (bilateral pulmonary vein + left atrial posterior wall isolation), including three 5 to 10 mm small incisions on each side of the chest wall. The complications and sinus rhythm maintenance of the patients were observed. Results The operative times were 140 min, 170 min, and 155 min. The three patients were in sinus rhythm immediately after the surgery. Mean blood loss was approximately 80 ml, mean intensive care unit (ICU) stay was 1 day, and average hospital stay was 7 days. No deaths and serious complications occurred. The three patients were still in sinus rhythm one week and one month after the operation, as measured by electrocardiogram. Conclusion Box Lesion bipolar radiofrequency treatment for atrial fibrillation therapy shows fast postoperative recovery. It is a promising procedure in atrial fibrillation treatment and is worthy of further study.

ObjectiveTo investigate the safety and efficacy of robot-assisted pulmonary lobectomy using da Vinci S System, and explore its advantages in minimally invasive surgery.
MethodsFrom May 2009 to May 2013, 12 patients with suspected non-small cell lung cancer (NSCLC) underwent robot-assisted lobectomy using da Vinci S System in Shanghai Chest Hospital. There were 6 male and 6 female patients with their age of 40-61 (52±8) years. Robotic instruments were used through a 12-mm observation port, two 8-mm thoracoscopic ports and a 12 to 40 mm utility incision without rib spreading. Perioperative data of the patients were collected and analyzed.
ResultsAll the 12 patients successfully received surgical resection. All types of lobectomy were performed, and all the procedures were radical resection. Each patient received 4 to 9 (5±1) stations of lymph node dissection. None of the patients underwent conversion to thoracotomy. There was no perioperative mortality or morbidity in this group. Chest drainage duration was 3-11 (8±7) days. Length of hospital stay was 6 to 18 (14±8) days. Operation time was 60 to 280 (185±78) minutes. Intraoperative blood loss was 20 to 200 (108±71) ml. There was no perioperative blood transfusion.
ConclusionsRobot-assisted lobectomy is initially proven a safe and effective procedure with enhanced visualization and better dexterity and stability than video-assisted thoracopscopic surgery. Thus surgical indications for robot-assisted lobectomy can be widened. Robot-assisted lobectomy is an important choice in the new age of minimally invasive thoracic surgery.
