With the diversification in surgical population and the progress of surgical techniques, the current clinical application of pre-operative pulmonary function assessment methods can hardly be qualified for accurately assessing whether lung cancer patients can tolerate surgical treatment and surgery-related risk. This paper focuses on the advantages and weaknesses of the commonly-used pul-monary function assessment methods, with the literature review of the clinical application status and progress of pulmonary function currently. We aim to achieve a reasonable evaluation of preoperative cardio-pulmonary function assessment, and sequentially reduce the risk and occurrence of surgical-related complications.

Objective To explore the utility of the diagnosis and typing to the ureterocysts using ultrasonography.Methods Based on the difference of anatomical location and appearance of cysts.the ureterocysts were divided into 4 types as fllowing:⑴Type of inside bladder:ureterocysts completely location in the inside of bladder.⑵Type of outside bladder:ureterocysts completely location in the outside of bladder.⑶Type of mixture:a part of cysts location in the inside of balader and other part localed in the outsider.⑷Type of ectopia:rare,cysts location in the neck of bladder or urethra usually complicated whith double kidney and abnormal location in the end of the ureter.Results UItrasonographic manifestations of 15 cases for ureterocele were reported.There were 3 cases of bilateral ureterocele and 18 cysts with a diameter 0 4cm～6 0cm. In which ,Type of inside bladder had 8 cases with 9cysts altogether .Type of outside bladdder had 2cases with 2 cysts only,Type of mixture had 5cases with 7 cysts;Type of ectopia had no one in this report .All cases were confirmed by ureteropyelography,in which,6 cases confirmed by surgical pathological examinations.Conclusion Ultrasonography has a high clinical value in the diagnosis and typing of ureterocele.

Background and purpose:With the development of the three-dimensional (3D) science, minimally invasive technology is going into the 3D period. While 3D laparoscope system has been widely accepted by surgeons because of its better visual effect and safer operations compared to traditional laparoscope system, this study aimed to evaluate the feasibility of 3D thoracoscope system in minimally invasive surgery for the treatment of thoracic diseases. Methods: A total of 96 cases of thoracic diseases were accomplished with KARL STORZ 3D thoracoscope during Mar. 2014 to Oct. 2014, including 33 cases of lobectomy, 2 cases of segmentectomy, and 10 cases of wedge resection of pulmonary tumor, 27 cases of mediastinal tumor, 20 cases of esophageal tumor and 4 case of esophageal achalasia. The data of operative time, bleeding volume, postoperative chest tube drainage and hospital time and postoperative complications were counted. Results: All the operations were completed successfully, without conversion to open surgery. All the operations cost 30 to 237 min. The operation of local resection lasted 30 to 120 min, with an average of 52 min, the operation of pulmonary lobectomy lasted 63 to 122 min, with an average of 75 min;the operation of mediastinal tumor resection lasted 35 to 125 min, with an average of 77 min;and the operation of esophageal diseases lasted 57 to 237 min, with an average of 189 min. The bleeding volumes were 2 to 85 mL, 15 to 72 mL, 30 to 186 mL and with the average of 50 mL, 47 mL, 118 mL in pulmonary, mediastinal and esophageal operations respectively. The time of postoperative chest tube drainage of each surgery was 1 to 5 days after pulmonary operations, 1 to 3 days after mediastinal operations, and 2 to 6 days after esophageal operations. The postoperative hospital time of pulmonary operation was 2 to 10 days, with an average of 6.3 days;the time of mediastinal operation was 3 to 6 days, with an average of 4.2 days;and the time of esophageal operation was 4 to 19 days, with an average of 13.3 days. No complications and tumor recurrence or metastasis were observed during the followed 3 months. Conclusion: 3D thoracoscope system not only preserves the minimally invasive advantage of video-assisted thoracoscopic surgery (VATS), it can also provide high-definition and stereoscopic vision and better sense of depth which facilitate the operation more precise and safer, thus operation time becomes shorter. Besides, 3D system possesses the advantage of natural vision similar to open surgery, thus it has an easier and shorter learning curve.
