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.
