OBJECTIVETo investigate the changes and influence factors for early postoperative pulmonary function of thoracotomy.

METHODSPre- and early postoperative pulmonary function was detected in 64 consecutive cases with optimal thoracotomy. Pain assessment was conducted before pulmonary function test, and the chief complaints of patients were recorded after the procedure. The changing curves of pulmonary function were made and the differences associated with groups, surgical styles, pain assessment, epidural analgesia, chief complaint and preoperative conditions were analyzed using SPSS10.0 medical statistic software.

RESULTSPulmonary function was severely lowered to (39 +/- 14)% of the base line on the first day. It was rehabilitated gradually, and recovered to (62 +/- 10)% of the base line on the 8th day. Epidural analgesia could improve pain relaxation and pulmonary function in some degree. Single-factor analysis showed that postoperative pain, postoperative day and surgical style were the significant influence factors for early postoperative pulmonary function. Multiple-factor analysis showed that preoperative pulmonary function, age and postoperative pain were the main factors, while surgical style had only weak effect on it.

CONCLUSIONSEarly postoperative pulmonary function is severely impaired by thoracotomy. It rehabilitate gradually with time. Improvement of preoperative pulmonary function, reducing surgical procedure injuries, especially injury to respiratory muscle system, and enough postoperative pain relief are the most important means that will reduce pulmonary function impairment and consequently reduce postoperative pulmonary complications.

The levels of pain, duration of approaching and closure, and surgical exposure associated with intercostal thoracotomy were compared between muscle-sparing and traditional techniques in 20 dogs. Postoperative pain was assessed based on numerical pain scores using behavioral observation, heart rate, respiratory rate, and wound palpation. Time for approaching and closure were measured, and the extent of intrathoracic organ exposure for the surgical procedures was described for each technique. There were significant differences in numerical pain scores at 2 h as well as 1, 2, 3, 4, 5, 6, and 7 days after surgery between the two groups (p < 0.0001). There was no significant (p = 0.725) difference in times for approaching and closure between the two groups. Compared to the traditional method, the muscle-sparing technique also achieved the desired exposure without compromising exposure of the target organs. Our results suggest that the muscle-sparing technique is more effective than the traditional method for providing a less painful recovery during the first 7 days after intercostal thoracotomy. Additionally, the muscle-sparing technique is as effective as the traditional modality for providing an appropriate time for approaching and closure during intercostal thoracotomy as well as adequate organ exposure for the surgical procedures.

BACKGROUND AND OBJECTIVEAtelectasis is a common complication after thoracotomy, and it may threaten patients' life if it was not treated correctly and properly. The aim of this article is to explore and discuss the prevention and treatment for atelectasis during the perioperative period, and also to explore new methods for reducing the perioperative mortality due to atelectasis after thoracotomy.

METHODSWe retrospectively reviewed the medical records of 374 lung cancer patients who underwent thoracotomy in our department between Jan 2007 and Nov 2009.

RESULTSAtelectasis occurred in 14 patients among all the 374 lung cancer patients who underwent thoracotomy. All the atelectasis returned to reexpansion after treatment.

CONCLUSIONThe incidence of atelectasis in these series is relatively low compared with the reports in literatures. Good perioperative preparation and perioperative treatment can remarkably decrease the incidence and mortality of atelectasis after thoracotomy in the treatment of lung cancer.

OBJECTIVETo report the experience in the diagnosis and treatment of pulmonary thromboembolism (PTE) in postthoracotomy patients and to analyze current problems in this field.

METHODSFrom January 2001 to June 2002 we diagnosed and treated 5 patient who had pulmonary thromboembolism, 72-168 hours after thoracotomy (male 4, female 1, mean age 63 years). Symptoms include breathholding, chest pain, palpitation, coma and so on. Physical signs include tachypnea, hypotension and tachycardia. We utilized spiral CT pulmonary artery angiography (SCTPA) and Doppler echocardiography to judge PTE. Pulmonary artery interventional therapy was used in 3 cases and total body thrombolysis in 1.

RESULTS4 patients recovered with no complication and recurrence; 1 patient died from congestive heart failure and respiratory failure.

CONCLUSIONDeep venous thrombosis (DVT) and PTE are related to the surgical intervention, chest tumor and thoracotomy is high risk factors. Screenage examination is primary to used. Pulmonary artery interventional therapy is safe to the postthoracotomy patients. Preventive measures is very important in the high-risk group.

OBJECTIVETo investigate the causes of acute respiratory distress (ARDS) after thoracotomy and to find out the measures to prevent ARDS.

METHODSThe characteristics of incidence, pathogenicity and treatment of ARDS after thoracotomy in 31 patients were analysed.

RESULTSThe patients who had chronic obstructive pulmonary disease, long history of smoking, hypertension were prone to ARDS. Injury to lung in operation, shock and pulmonary infection probably caused ARDS. Clearing away respiratory tract secretion, preserving of a clear airway, controlling pulmonary infection, alleviating pneumonedema by diuresis, early executing tracheotomy or mechanic assistant ventilation by tracheointubation were keys to rescuing patients successfully.

CONCLUSIONSIt is suggested that multi factors were related to ARDS after thoracotomy. Shock, injury to lung in operation, pulmonary infection, are important factors that lead to post-operative ARDS after thoracotomy. Early treatment can reduce mortality of ARDS.

OBJECTIVEVideo-assisted thoracoscopic (VATS) esophagectomy has been performed for more than 10 years in China. However, compared with the conventional esophagectomy via right thoracotomy, whether VATS esophagectomy has more advantages or not in the lymph node (LN) dissection and prevention of perioperative complications is still controversial and deserves to be further investigated. The aim of this study was to explore whether there are significant differences in this issue between the two surgical modalities or not.

METHODSThe results of lymph node dissection and perioperative complications as well as other parameters in the patients treated by VATS esophagectomy and those by conventional esophagectomy via right thoracotomy at our department from May 1, 2009 to July 30, 2013 were compared using SPSS 16.0 in order to investigate whether there was any significant difference between these two treatment modalities in the learning curve stage of VATS esophagectomy.

RESULTSOne hundred and twenty-nine cases underwent VATS esophagectomy between May 1, 2009 and July 30, 2013, and another part 129 cases with the same preoperative cTNM stage treated by conventional esopahgectomy via right thoracotomy were selected in order to compare the results of lymph node dissection and perioperative complications as well as other parameters between those two groups of patients. There were no significant differences in the sex, age, lesion locations and cTNM stage between these two groups. The total LN metastatic rate in the VATS esophagectomy group was 35.7% and that of the conventional esophagectomy group was 37.2% (P > 0.05). The total average number of dissected lymph nodes was 12.1 vs. 16.2 (P < 0.001). The average dissected LN stations was 3.2 vs. 3.6 (P = 0.038). The total average number of dissected LN along the left recurrent laryngeal nerve was 2.0 vs. 3.7 (P = 0.012). The total average number of dissected LN along the right recurrent laryngeal nerve was 2.9 vs. 3.4 (P = 0.231). However, there was no significant difference in the total average number of dissected LN in the other thoracic LN stations, and in the perioperative complications between the two groups. The total postoperative complication rate was 41.1% in the VATS group versus 42.6% in the conventional group (P = 0.801). The cardiopulmonary complication rate was 25.6% vs. 27.1% (P = 0.777). The death rate was the same in the two groups (0.8%). The VATS group had less blood infusion (23.2% vs. 41.8%, P = 0.001) and shorter hospital stay (15.9 days vs. 19.2 days, P = 0.049) but longer operating time (161.3 min vs. 127.8 min, P < 0.01).

CONCLUSIONSIn the learning curve stage of VATS esophagectomy, compared with the conventional esophagectomy, less LN number and stations can be dissected in the VATS group due to un-skillful VATS manipulation, especially it is more difficult in the LN dissection along the left recurrent laryngeal nerve. Therefore, it is more suitable to select patients with early esophageal cancer without obvious enlarged lymph nodes for VATS esophagectomy in the learning curve stage.

Esophageal perforation after endoscopic forceful pneumatic dilatation for achalasia is a devastating complication and surgical treatment is necessary. A 65-yr-old man and a 54-yr-old woman referred for esophageal perforation two hours after pneumatic dilatation and during the procedure, respectively. Gastroplasties through thoracotomy were performed in both cases and their recoveries were uneventful. The esophagogram with gastrografin on the post-operative 8th day did not show any passage disturbance or leakage at the anastomosis site. On the follow-up endoscopy 4 to 6 months after operation revealed that reflux esophagitis of LA classification A were noted in the both patients. They did not complain any reflux symptom or dysphagia for 9 to 13 months after operation. Instead of the most widely used procedure; primary repair of perforation site, wrapping with intercostal muscle flap and esophagomyotomy, gastroplasty was performed in two cases of iatrogenic esophageal perforation in achalasia and experienced good results.

Pulmonary lymphangioleiomyomatosis has been observed almost exclusively in women, usually in their reproductive years. Exacerbations with pregnancy and after hormonal manipulation have been documented, and it has been suggested that its pathogenesis is due to the influence of hormonal(estrogenic) stimulus. The clinical, roentgenographic, and histopathologic features of this case of pulmonary lymphangioleiomyomatosis in a 22-year-old male are all characteristic of those described in prior reports, except for the patient's sex. With the following case of pulmonary lymphangioleiomyomatosis in a male, we suggest the possibility of the existence of an additional pathogenetic mechanism.

BACKGROUNDIn clinical practice, the mechanisms underlying chronic post-surgical pain (CPSP) remain insufficiently understood. The primary goals of this study were to determine the incidence of chronic pain after thoracic surgery and to identify possible risk factors associated with the development of chronic post-thoracotomy pain in Chinese patients. The secondary goal was to determine whether the difference between pre- and post-operative white blood cell (WBC) counts could predict the prevalence of CPSP after thoracotomy. The impact of chronic pain on daily life was also investigated.

METHODSWe contacted by phone 607 patients who had undergone thoracotomy at our hospital during the period February 2009 to May 2010. Statistical comparisons were made between patients with or without CPSP.

RESULTS

RESULTSwere ultimately analyzed from 466 qualified patients. The overall incidence of CPSP was 64.5%. Difference between pre- and post-operative WBC counts differed significantly between patients with or without CPSP (P < 0.001) and was considered as an independent risk factor for the development of CPSP following thoracotomy (P < 0.001). Other predictive factors for chronic pain included younger age (< 60 years, P < 0.001), diabetes mellitus (P = 0.023), acute post-operative pain (P = 0.005) and the duration of chest tube drainage (P < 0.001). At the time of interviews, the pain resulted in at least moderate restriction of daily activities in 15% of the patients, of which only 16 patients had paid a visit to the doctor and only three of them were satisfied with the therapeutic effects.

CONCLUSIONSChronic pain is common after thoracotomy. WBC count may be a new independent risk factoring surgical patients during peri-operative period. Besides, age, diabetes mellitus, acute post-operative pain, and duration of chest tube drainage may also play a role in chronic post-surgical pain occurrence.

OBJECTIVE: To study the clinical effect of the oxygen drive aerosol in halation with budesonide and ambroxol in the prevention of adult post-thoracotomy pneumonia. METHODS: This was a randomized, open and parallel controlled trial. We chose 80 cases of patients in the department of thoracic surgery in the First Affiliated Hospital of Xi'an Jiaotong University which fitted our criteria as the research object. The selected patients were randomly divided into the active group and the control group, and the active group underwent oxygen drive aerosol inhalation (2 mg budesonide combined 60 mg ambroxol) for 3 days before operation, and the control group without preoperative aerosol inhalation, and their postoperative therapy was the same. RESULTS: The baseline data showed that the differences in sex, age, disease and smoking were not statistically significant between the two groups, P>0.05. The results of blood gas analysis before 12 hours of operation suggested that, the PaO₂and PaCO₂values of the active group were (88.40±9.40) mmHg and (38.30±6.10) mmHg; The PaO₂and PaCO₂ values of the control group were (85.09±7.18) mmHg and (41.21±3.15) mmHg. And the two groups' P values were 0.029 and 0.011, with statistical differences. There were 3 patients who developed postoperative pneumonia out of 40 patients in the active group, the incidence was 7.50%, but the incidence of control group was 25.00%. The P value was 0.034, with statistical differences. We also analyzed the influence of different diseases and surgical methods on postoperative pneumonia, and the results showed that in the active group and the control group, the incidence of postoperative pneumonia in the patients with esophageal cancer was lower than that in lung cancer patients, and there was a statistically significant difference (P<0.05). In the active group, the numbers of pulmonary deed resection, lobectomy and pulmonary sleeve resection were 2, 21 and 1 cases respectively, and the corresponding numbers in the control group were 2, 21 and 2. Among the two groups, the incidence of postoperative pneumonia in the patients with different surgical methods of lung cancer was statistically significant (P<0.05). CONCLUSION If we implement respiratory preparation with budesonide plus ambroxol inhalation for 3 days before operation, we can greatly reduce the incidence of postoperative pneumonia?
