@#Objective    To evaluate the feasibility and clinical value of robot-assisted lung segmentectomy through anterior approach. Methods    We retrospectively analyzed the clinical data of 77 patients who underwent robotic lung segmentectomy through anterior approach in our hospital between June 2018 to October 2019. There were 22 males and 55 females, aged 53 (30-71) years. Patients' symptoms, general conditions, preoperative imaging data, distribution of resected lung segments, operation time, bleeding volume, number of lymph node dissected, postoperative duration of chest tube insertion, drainage volume, postoperative hospital stay, postoperative complications, perioperative death and other indicators were analyzed. Results    All operations were successfully completed. There was no conversion to thoracotomy, serious complications or perioperative death. The postoperative pathology revealed early lung cancer in 48 patients, and benign tumors in 29 patients. The mean clinical parameters were following: the robot Docking time 1-30 (M=4) min, the operation time 30-170 (M=76) min, the blood loss 20-400 (M=30) mL, the drainage tube time 2-15 (M=4) days, the drainage fluid volume 200-3 980 (M=780) mL and the postoperative hospital time 3-19 (M=7) days. Conclusion    Robotic lung segmentectomy through anterior approach is a safe and convenient operation method for pulmonary nodules.

@#Objective    To investigate the short-term effects of Da Vinci robot-assisted Nissen fundoplication in the treatment of refractory gastroesophageal reflux disease (rGERD), and to evaluate the safety and efficacy of its surgical treatment. Methods    A total of 40 patients with rGERD treated by Da Vinci robot-assisted surgery from October 2016 to November 2019 in our hospital were collected. There were 23 males and 17 females at age of 34-76 (61±23) years. The related clinical data were retrospectively analyzed, and the operation skills of Da Vinci robot-assisted Nissen fundoplication with rGERD were summarized. Results    There was no perioperative death or serious complication such as esophagogastric fistula. Postoperative reflux symptoms were significantly improved. DeMeester scores after surgery (39.79±35.01 points vs. 2.61±2.40 points, P=0.029), lower esophageal sphincter pressure (8.74±7.21 mm Hg vs. 24.56±8.76 mm Hg, P=0.020), integrated relaxation pressure (7.29±7.21 mm Hg vs. 16.49±9.99 mm Hg, P=0.023), distal contractile integral (600.49 ± 665.30 mm Hg·s·m vs. 510.99 ± 580.60 mm Hg·s·m, P=0.042), GERD-Q scale score (12.98±2.39 points vs. 7.59±1.11 points, P=0.033) were significantly improved compared with those before surgery. Postoperative dysphagia was found in 2 patients. And dysphagia was alleviated after diet adjustment and other treatments. Conclusion    Da Vinci robot-assisted Nissen fundoplication is a safe and effective treatment for rGERD.

@#Objective    To evaluate the timing of chest tube removal after resection of lung or esophageal cancer. Methods    A prospective randomized controlled study was performed. From June 2014 to February 2016, 150 patients suspected as the cancer of lung or esophagus undergoing neoplasm resection and lymph node dissection in our single medical unit were classified into 3 groups according to the random number generated by SPSS17.0 with 50 patients in the each group. The drainage volume for chest tube removal was ≤100 mL/d in the group Ⅰ, 101–200 mL/d in the group Ⅱ, and 201–300 mL/d in the group Ⅲ. Chest radiography was performed 48 hours following chest tube removal. Results    The 127 patients (108 males and 19 females, with an average age of 59.0±8.7 years) eligible for analysis consisted of 45 patients in the group Ⅰ, 41 in the group Ⅱ, and 41 in the group Ⅲ respectively after the 23 patients were excluded from this study who were diagnosed as benign lesions through intraoperative frozen pathology (n=20) and postoperative complications (empyema in 2 patients and chylothorax in 1 patient). Age, sex, types of neoplasm, and comorbidities except procedures via video-assisted thoracic surgery (and laparoscopy) showed no significant difference among the three groups (P>0.05). No mortality was observed in this study. There were postoperative complications in 6 patients and its distribution had no statistical differences among the three groups (P>0.05). The mean postoperative duration of chest tube was 181.0±68.2 h, 111.0±63.1 h, 76.0±37.2 h, the mean drainage volume was 1 413.0±500.9 mL, 1 005.0±686.4 mL, 776.0±505.8 mL, and the mean hospital stay time following chest tube removal was 19.0±9.7 d, 14.0±8.0 d, 9.0±4.8 d in the group Ⅰ,Ⅱ and Ⅲ,  respectively; there was a significant difference among the three groups (P=0.000). The 13 patients required reintervention after chest tube removal due to pleural effusion accumulation and it had no difference among the three groups (P>0.05). Chest pain relieved essentially after chest tube removal in all patients. Conclusion    A drainage volume of ≤300 mL/d as a threshold for chest tube removal after resection of lung or esophageal cancer can shorten postoperative hospital stay and accelerate early recovery of the patients.
