Abstract： Objective To investigate the indications， surgical techniques and postoperative complication management of transhiatal esophagectomy without thoracotomy for patients with esophageal cancer. Methods We retrospectively analyzed the clinical records of 105 patients with esophageal cancer who underwent transhiatal esophagectomy without thoracotomy in the First Affiliated Hospital of Nanjing Medical University between July 2002 and July 2010， including 28 patients who received video-assisted mediastinoscopy. There were 59 male patients and 46 female patients with their average age of 63 （48-81） years. There were 51 patients with upper thoracic esophageal cancer， 18 patients with middle thoracic esophageal cancer and 36 patients with lower thoracic esophageal cancer. Surgical outcomes and safety were evaluated. Results Mean operation time was 153 （140-210） minutes， mean intraoperative blood loss was 150 （100 to 250） ml， and mean hospital stay was 15 （10-35） days. There was no in-hospital death or residual tumor cells in esophagus stumps. Twenty-seven patients had postoperative complications， including 3 patients with anastomotic leakage at neck， 4 patients with recurrent laryngeal nerve injury， 5 patients with pleural effusion， 2 patients with pneumothorax， 3 patients with pneumonia， 3 patients with arrhythmia， 1 patient with chylothorax， 2 patients with incision infection， 2 patients with delayed gastric emptying， and 2 patients with anastomotic stenosis， who were all cured after treatment. Ninety-seven patients were followed up from 16 months to 5 years， and 8 patients were lost during follow-up. During follow-up， there were 94 patients who had lived for 1 year， 67 patients who had lived for 3 years， and 34 patients who had lived for 5 years postoperatively， and some patients needed further follow-up. Conclusion Transhiatal esophagectomy without thoracotomy is a minimally traumatic procedure and can provide fast postoperative recovery. It is especially suitable for patients with stageⅡor earlier esophageal cancer who can’t tolerate or aren’t suitable for transthoracic esophagectomy.
Objective To assess clinical outcomes of therapeutic video-mediastinoscopy （VMS）. Methods Clinical data of 82 patients undergoing VMS in Zhongshan Hospital of Dalian University from December 2008 to October 2011 were retrospectively analyzed. Among them，24 patients received therapeutic VMS，including 18 men and 6 women with their median age of 56 （22-81） years. Three patients underwent operation through a neck incision，4 patients through a parasternal incision，and 17 patients through a lateral intercostal incision. Five patients received local anesthesia and basal anesthesia，and all the other patients received general anesthesia through single-lumen or double-lumen endotracheal intubation. Results Twelve patients with pleural effusion underwent pleural or lung biopsy and talc pleurodesis. Pathology examination showed malignant diseases in 11 patients and tuberculous pleural effusion in 1 patient. The median operation time was 35 （30-50） minutes，and postoperative hospital stay was 3-6 days. These patients were followed up for 1 month without recurrence of pleural effusion. Ten patients with mediastinal mass received pathological diagnosis and complete mass resection with their median operation time of 55 （30-270） minutes and median hospital stay of 7 （5-40） days. Two patients with hyperhidrosis underwent bilateral intercostal VMS sympathectomy. Their operation time was 60 minutes and 50 minutes respectively，and their hospital stay was 3 days. Postoperatively their sweating symptoms obviously resolved. They were followed up for 3 months，and their hands，feet and armpit were warm and dry. There was no in-hospital death in this group. Two patients （8.3%） had postoperative complications including 1 patient with phrenic nerve injury and another patient with pneumonia. Opioid analgesic drugs were not used postoperatively in 9 patients. Conclusion Therapeutic VMS is a safe，effective，minimally invasive and cosmetic procedure，but it is not suitable for resection of a large mediastinal mass.
Objective To evaluate the clinical role of video-assisted mediastinoscopy and its safety and effectiveness in the diagnosis of thoracic disease. Methods We reviewed the clinical data of consecutive 40 patients (25 males and 15 females with an average age of 54.6 years) who received video-assisted mediastinoscopic surgery in our department of thoracic surgery from December 2011 to November 2016, including mediastinal lymph node biopsy in 27 patients, mediastinal primary lesions biopsy in 8, bronchial cystectomy in 3 and esophageal dissection in 2. Results The histological results were positive in 20 patients (73.1%) in mediastinal lymph node biopsy, including granulomatous mediastinitis in 14 and metastasis in 6 (non-small cell lung cancer in 4, Ewing sacoma in 1 and small cell lung cancer in 1) and reactive proliferation in 7 (26.9%). In mediastinal primary lesions biopsy, the accuracy rate of diagnosis was 100.0%. The pathologic results were malignant in all patients, including small cell lung cancer in 5, adenoid cystic carcinoma in 1, squamous carcinoma in 1 and adenocarcinoma in 1. In patients who received the bronchial cystectomy, no recurrence was found during at least 2 years follow-up. There was one patient with severe complication (innominate artery injury). Two patients suffered transient laryngeal recurrent nerve palsy with hoarseness and two patients incision secretion. Conclusion Video-assisted mediastinoscopic surgery is effective and safe and dissection should be careful in granulomatous mediastinitis to avoid the great vessel injures.
Objective To compare the different surgical treatment methods of thymoma combined with myasthenia gravis (MG), and to discuss the clinical effectiveness of thoracoscopic combined mediastinoscopic extended thymectomy. Methods We retrospectively analyzed the clinical data of 58 patients of thymoma combined with myasthenia gravis in Northern Jiangsu People's Hospital between 2011 and 2016 year. According to the operation method, the patients were divided into three groups including a group A for thoracoscopic thymectomy (n=32), a group B for thoracoscopic combined mediastinoscopic thymectomy (n=15), and a group C for transsternal thymectomy (n=11). The clinical effects were observed and compared. Results In the group A and the group B, the bleeding volume, postoperative hospital stay and other complications were significantly lower than those in the group C with statistical differences (P<0.05). The incidence of myasthenic crisis in the group B (6.7%) was less than that in the group C (36.4 %), but the difference was not statistically different (P=0.058). The operation time of the three groups was 122.0 ± 39.4 min, 130.3 ± 42.5 min, and 142.3 ± 40.8 min respectively with no statistical difference between the two groups (P>0.05). The rate of dissection grade in the group B (grade 1, 12 patients, 80%) was significantly greater than that in the group A (grade 1, 14 patients, 43.8%,P<0.05). The effective rate of the group A, the group B, the group C was 84.4%, 93.3% and 90.9%, respectively with no statistical difference between groups (P>0.05). Conclusion The thoracoscopy combined mediastinoscopic thymectomy not only has the advantages of less trauma, quicker recovery and fewer complications, but also can more thoroughly clean the thymus and adipose tissue, which can achieve the same therapeutic effect as the transsternal thymectomy.
