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 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.

Objective To evaluate the prediction value on distant metastases of fib bone marrow micrometastases (BMM) of patients with non-small lung cancer ( NSCLC ). Methods From January 2003 to March 2006, 168 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMM by using immnnohistochemistry. The sensitivity and specificity of the rib bone marrow micrometastases technique were also calculated. Receiver operating characteristic curve (ROC curve)was drawn according to data. Results Occult BMM were detected in 29.76 %(50/168) of patients with NSCLC. 15(29.76 %) patients developed metastases in the 50 patients with BMM and 15 (12.71%) patients developed metastases in the 118 patients without BMM. The sensitivity and the specificity of the technique was 61.54 % and 79.84 %. The false negative rate was 38.46 % and the false positive rate was 20.16 %. The positive predictive value, negative predictive value and Youden' s index were 87.5 %, 93.33 %, 74.33 % respectively. Conclusion The detection of BMM could predict the distant metastases of non-small lung cancer patients through receiver operating characteristic curve evaluation, however, the detecting sensitivity should be improved.
