RESUMO
@#Objective To investigate short-term outcomes of robot-assisted Heller-Dor myotomy (RAHM-Dor) for achalasia of cardia and our learning curve experience. Methods The clinical data and recent follow-up results of 42 patients who received RAHM-Dor from November 2015 to January 2020 in the Department of Thoracic Surgery of the First Affiliated Hospital of Nanchang University were retrospectively analyzed, including 20 males and 22 females with a mean age of 40.8±18.4 years. Results Dysphagia was the most common symptom, followed by heartburn and regurgitation. The mean operation time was 122.8±23.9 min. The mean blood loss was 47.5±32.7 mL. Two patients suffered mucosal injury, and successfully repaired by suturing during surgery. There was no esophageal fistula, conversion to an open operation or perioperative death in this series. The median length of hospital stay was 8 (6, 9) d. In all patients, the Stooler and Eckardt scores of postoperative 1, 6 and 12 months decreased compared to those of pre-operation (P<0.001). Conclusion RAHM-Dor is a safe and feasible avenue for the treatment of achalasia of cardia, and can achieve a satisfying short-term results. The learning curve shows a transition to the standard stage from the learning stage after 16-18 operations.
RESUMO
With the popularization of low-dose computed tomography (LDCT) scanning,the rate of the diagnosis of primary lung cancer for early-stage non-small cell lung carcinoma (NSCLC) is increasing,mainly because of a growing rate of solitary pulmonary nodule and ground-glass nodule.For these patients,recent studies have shown that segmentectomy and lobectomy have similar oncologic effects,while they can retain more lung function and improve the quality of life,so anatomical segmental resection is an alternative operation.In recent years,the three-dimensional reconstruction technology based on medical imaging has developed rapidly,which can be used to understand the anatomical structure,nodule position,spatial relationship,design of surgical path and other advantages in preoperative,and plays an important role in the thoracoscopic anatomical segmental resection with complex anatomical structure and individual differences.This paper reviews the application of three-dimensional reconstruction technology in segmental lung resection,and briefly introduces the application of this technology in precise segmental lung resection.
