Objective To observe the effects and benefits of the gastroscopy-assisted thoracoscopic modified Heller operation for the treatment of achalasia of cardia. Methods Retrospective analysis was conducted on the clin﹣ical data of 33 cases in our hospital. The surgical approach was gastroscopy-assisted thoracoscopic modified Heller operation. The intraoperative and postoperative effect and complications were observed. All patients were followed up for six months. Results After operation 33 achalasia patients' symptom of obstruction is alleviated. 1 case changed to open operation because of severe adhesion; 4 cases esophageal mucosal were injured and need to be repair assisted by thoracoscope. 1 case had esophagopleural fistula after operation and was cured by conservative treatment in one month. 1 case had gastroesophageal reflux symptoms after operation and relief symptoms after conservative treatment. All patients were follow-up more than six months, only 1 patient recured eating obstruction in 3 months after opera﹣tion, and was cured by gastroscopic expanding treatment. Conclusions The results of gastroscopy-assisted thoraco﹣scopic modified Heller operation to patients with Achalasia is significant. The operation is easy to perform and the complications is less, it can be promoted and applied in clinical practice.

Objective To evaluate the effect of plastic surgery for scar contracture after hand burn.Methods Clinical treatment data of 56 patients with scar contracture after hand burn was collected from December 2011 to December 2016.Different surgery methods were adopted to treat the scar contracture after hand burn according to different degree,different sites and different range.Results All cases were operated successfully,and the appearance and function of the hands were almost recovered during the 6 months' follow-up,without contracture again.Conclusion Appropriate surgical programs should be used in scar contracture with different parts and degrees,and reasonable postoperative rehabilitation can improve the function and appearance of hands better,which can avoid secondum contracture.

Objective To compare the effect of postoperative intercostal nerves cryoanalgesia and patient controlled epidural analgesia (PCEA) in patients undergoing thoracic surgery. Methods From April 2006 to May 2008,89 patients undergoing thoracic surgery were randomly divided into intercostal nerves cryoanalgesia group (group A,47 cases) and PCEA group (group B,42 cases). The scores of pain, use of pain medication and time of out-of-bed activity after the operation were used to evaluate the effect of pain between two groups. Results The scores of pain in group A and group B were (1.49 ± 0.80) and (2.43 ± 1.21) scores respectively. There were significant differences in the scores of pain. The use of pain medication [(1.28 ± 0.62) times vs (2.02 ± 1.05) times]and time of out-of-bed activity after the operation [(43.15 ± 12.22) h vs (64.10 ± 14.25) hi were significant difference between the two groups(P< 0.05). Conclusions For reducing the post- thoracotomy pain,intercostal nerves cryoanalgesia is superior to PCEA. Intercostal nerves cryoanalgesia can provide satisfactory analgesia after thoracic surgery.
