Meta Analysis of Non-penetrating Trabecular Surgery versus Trabeculectomy for the Treatment of Open Angle Glaucoma

This study compared the efficacy of non-penetrating trabecular surgery and trabeculectomy for the treatment of open angle glaucoma. We searched the Cochrane Library, PUBMED （1966 to 2009）, Embase （1980 to 2009） and CMB-disk （1979 to 2009） for the randomized clinical trials （RCT） concerning the two treatment strategies. The reports, including the papers listed in bibliographies, were evaluated against a set of quality criteria and the RCTs that satisfied the criteria were selected and subjected to Meta analysis by employing the Cochrane Collaboration＇s RevMan 4.5 software package. A total of nine RCTs were included in the study. The analyses of the reports showed that, 12 months after surgery, there was significant difference in the reduction of interocular pressure （IOP） between non-penetrating trabecular surgery and trabeculectomy （Z=6.05 P0.00001）. There also existed statistically significant difference in the reduction of IOP at the censored time between the two procedures （Z=4.92, P0.00001）. Difference in the success rate was also found between the two surgeries （Z=3.82, P=0.0001）. It is concluded that, compared with the non-penetrating trabeculectomy, the traditional trabeculectomy could reduce IOP more and had higher success rate while the non-penetrating trabecular surgery is associated with lower postoperative complications.

Laparoscopic and endoscopic co-operative surgery for nonampullary duodenal tumors

AIM To assess the safety and feasibility of laparoscopic and endoscopic co-operative surgery(LECS) for early nonampullary duodenal tumors.METHODS Twelve patients with a non-ampullary duodenal tumor underwent LECS at our hospital. One patient had two mucosal lesions in the duodenum. The indication for this procedure was the presence of duodenal tumors with a low risk for lymph node metastasis. In particular, the tumors included small(less than 10 mm) submucosal tumors(SMT) and epithelial mucosal tumors, such as mucosal cancers or large mucosal adenomas with malignant suspicion. The LECS procedures, such as full-thickness dissection for SMT and laparoscopic reinforcement after endoscopic submucosal dissection(ESD) for epithelial tumors, were performed for the 13 early duodenal lesions in 12 patients. Here we present the short-term outcomes and evaluate the safety and feasibility of this new technique.RESULTS Two SMT-like lesions and eleven superficial epithelial tumor-like lesions were observed. Seven and Six lesions were located in the second and third parts of the duodenum, respectively. All lesions were successfully resected en bloc. The defect in the duodenal wall was manually sutured after resection of the duodenal SMT. For epithelial duodenal tumors, the ulcer bed was laparoscopically reinforced via manual suturing after ESD. Intraoperative perforation occurred in two out of eleven epithelial tumor-like lesions during ESD; however, they were successfully laparoscopically repaired. The median operative time and intraoperative estimated blood loss were 322 min and 0 mL, respectively. Histological examination of the tumors revealed one adenoma with moderate atypia, ten adenocarcinomas, and two neuroendocrine tumors. No severe postoperative complications(Clavien-Dindo classification grade Ⅲ or higher) were reported in this series, but minor leakage secondary to pancreatic fistula occurred in one patient.CONCLUSION LECS can be a safe and minimally invasive treatment option for non-ampullary early duodenal tumors.

Long-term survival outcomes of video-assisted thoracic surgery for patients with non-small cell lung cancer

Background： Video-assisted thoracic surgery （VATS） has been shown to be a safe alternative to conventional thoracotomy for patients with non-small cell lung cancer （NSCLC）. However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival. Methods： Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival. Results： Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients （69%）. The median 5-year overall survival for Stage Ⅰ, Ⅱ, Ⅲ and Ⅳ disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis. Conclusions： VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectableNSCLC

Outcomes of patients with cirrhosis undergoing non-hepatic surgery:Risk assessment and management

The reported mortality rates in patients with cirrhosis undergoing various non-transplant surgical procedures range from 8.3% to 25%. This wide range of mortality rates is related to severity of liver disease, type of surgery, demographics of patient population, expertise of the surgical, anesthesia and intensive care unit team and finally, reporting bias. In this article, we will review the pathophysiology, morbidity and mortality associated with non-hepatic surgery in patients with cirrhosis, and then recommend an algorithm for risk assessment and evidence based management strategy to optimize post-surgical outcomes.

ADJUVANT CHEMOTHERAPY FOLLOWING RADICAL SURGERYFOR NON-SMALL CELL LUNG CANCER:A RANDOMIZED STUDY

Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage I–III) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX) 300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 dl, cisplatin (DDP) 20 mg/m2, d1–5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600–900 mg/d for 1 year (adjuvant chemotherapy group). The other 35 patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4% in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage III was 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage I–II in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage III, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

Comparing a non-invasive hemodynamic monitor with minimally invasive monitoring during major open abdominal surgery

As part of the enhanced recovery after surgery （ERAS） protocol, the goal-directed fluid management with hemodynamic monitoring can effectively guide perioperative fluid use and significantly improve the outcomes in highrisk patients undergoing major surgeries. Several minimally invasive and non-invasive monitoring devices are commercially available for clinical use. As part of an internal evaluation, we reported the results from three different hemodynamic monitoring devices used in a patient undergoing a major abdominal surgery.

Effect of Oxygen Therapy by Venturi Mask versus Non Invasive Ventillation on the Outcome of Patients Who Devolope Hypoxia after Open Heart Surgery

Background: Cardiothoracic surgery is a common cause of acute respiratory failure and is associated with increased morbidity and mortality. We aimed to compare the outcomes of open heart surgery patients treated using oxygen delivery devices with patients who receive NIV as a first-line therapy for hypoxemic respiratory failure. Materials and Methods: 40 patients who developed acute hypoxemic respiratory failure after open heart surgery and admitted to cardiothoracic ICU 20 patients received NIV and 20 patient received oxygen by venture mask. For all patients the following measurements were performed before and after CPAP AND Venture use: CBC, blood urea, serum creatinine body temperature, chest X-ray, Arterial blood gases (arterial pH, sodium bicarbonate, pcO2, SpO2 and PaO2-to-FiO2 ratio). Results: Mean PO2 and SO2 have increased after using of both venture and Cpap, increase in both PCO2 and HCO3 levels after using Venturi mask, CPAP mask was superior to venturi mask in avoiding the need of intubation, decreasing The ICU stay median length and also median length of hospitalization, all were lower in CPAP group than venture group. Also the mortality rate was lower in CPAP group than the venturi group. Conclusion: Using CPAP mask in severe AHRF following open heart surgery can avoid intubation, decreases the levels of tachypnea and arterial hypoxemia, decreases ICU stay, the length of hospitalization and also decreases the mortality rate compared with patients receiving high-concentration oxygen therapy with venture mask.

Impact of topical nonsteroidal anti-inflammatory drugs in prevention of macular edema following cataract surgery in diabetic patients

AIM： To evaluate the efficacy of prophylactic administration of topical non-steroidal anti-inflammatory drugs（NSAIDs） on macular edema following cataract surgery in diabetic patients, and to compare between types of NSAIDs（ketorolac tromethamine 0.4% and nepafenac 0.1%）. METHODS： Group 1（control） received artificial tears substitute as a placebo group, group 2（nepafenac） received topical nepafenac 0.1%, and group 3（ketorolac） received topical ketorolac tromethamine 0.4%. Patients were examined postoperatively after completing one week, one month, two months and three months＇ intervals for evaluating cystoid macular edema（CME） development. The main study outcomes were achieving the best corrected visual acuity（BCVA） and change in the central macular thickness（CMT） measured with optical coherence topography（OCT）.RESULTS： Eighty eyes of 76 patients were included in this study. BCVA showed a statistically significant difference at the third month postoperative follow up between the control group and the NSAIDs groups（P=0.04）. There was an increase in the CMT in all cases starting from postoperative first week until third month. CMT showed a statistically significant difference between control group and NSAIDs groups from postoperative first month until third month（P=0.008, 0.027, 0.004）. There was no statistically significant difference between nepafenac and ketorolac groups in BCVA and OCT CMT. CONCLUSION： Prophylactic preoperative and postoperative NSAIDs may have a role in reducing the frequency and severity of CME in diabetic eyes following cataract surgery.

Surgery Versus Stereotactic Radiosurgery for Single Synchronous Brain Metastasis from Non-Small Cell Lung Cancer

Objective： The aim of this study is to compare the effectiveness of surgery with stereotactic radiosurgery （SRS） for patients with a single synchronous brain metastasis from successfully treated non-small cell lung cancer. Methods： Between 1995 and 2002, 53 patients underwent resection of both primary non-small cell lung cancer and the associated single brain metastasis. There were 33 men and 20 women with a mean age of 57 years （range, 32-85 years）. At the time of diagnosis, 42 patients experienced lung cancer related symptoms, whereas 11 patients experienced brain metastases-related symptoms. 42 patients had received thoracic surgery first, and 11 patients had undergone neurosurgery or radiosurgery first. Pneumonectomy was performed in 9 out of 42 patients （21.4%）, lobectomies in 30 （71.4%）, and wedge resection in 3 （7.2%）. 48 patients （90.5%） underwent complete lymphadenectomy. 35 patients underwent brain metastasectomy. 18 underwent SRS. Results： There was no postoperative mortality and severe complications after either lung or brain surgery. Histology showed 34 adenocarcinomas, 16 squamous cell carcinomas, and 3 large cell lung cancers. 15 patients （28.3%） had no evidence of lymph node metastases （No）, 20 patients （37.7%） had hilar metastases （N1）, and 18 patients （34%） had mediastinal metastases （N2）. The 1-, 2-, 3- and 5-year overall survival rates were 49%, 19%, 10%, and 5%, respectively. The corresponding data for neurosurgery group were 55%, 17%, 11%, and 6%, respectively. The median survival time was 13 months. For SRS group the corresponding data were 44.8%, 20.9% 10.5%, and 2%, respectively. The median survival time was 14 months. The differences between the two groups were not significant （P〉0.05）. In lymph node negative patients （No）, the overall 5-year survival rate was 10%, as compared with a 1% survival rate in patients with lymph node metastases （N1-2）. The difference was significant （P〈0,01）. For adenocarcinomas, the 5-year survival rate was 5%. The correspondent data for squamous cell lung cancers was 3%. The difference was not significant （P〉0.05）. Conclusion： Although the overall survival rate for patients who have brain metastases from NSCLC is poor, surgical resection or radiosurgery may be beneficial in a select group of patients with synchronous brain metastases and lung cancer without lymph node metastases.

Partial removal of the pulmonary artery in video-assisted thoracic surgery for non-small cell lung cancer

Lobectomy with partial removal of the pulmonary artery in video-assisted thoracic surgery （VATS） currently remains a challenge for thoracic surgeons. We were interested in introducing pulmonary vessel blocking techniques in open thoracic surgery into video-assisted thoracic surgery （VATS） procedures. In this study, we reported a surgical technique simultaneously blocking the pulmonary artery and the pulmonary vein for partial removal of the pulmonary artery under VATS. Seven patients with non-small-cell lung cancer （NSCLC） received lobectomy with partial removal of the pulmonary artery using the technique between December 2007 and March 2012. Briefly, rather than using a small clamp on the distal pulmonary artery to the area of invading cancer, we replaced a vascular clamp with a ribbon and Hem-o-lock clip to block the preserved pulmonary veins so as to prevent back bleeding and yield a better view for surgeons. The mean occlusion time of the pulmonary artery and pulmonary veins were 44.0±10.0 and 41.3±9.7 minutes, respectively. The mean repair time of the pulmonary artery was 25.3±13.7 minutes. No complications occurred. No patients showed abnormal blood flow through the reconstructed vessel. There were no local recurrences on the pulmonary artery. In conclusion, the technique for blocking the pulmonary artery and veins is feasible and safe in VATS and reduces the risk of abrupt intraoperative bleeding and the chance of converting to open thoracotomy, and extends the indications of VATS lobectomy.

Patient-Reported Outcomes of Surgery of Non-Small Cell Lung Cancer: Evaluation Based on the Questionnaires of Anti-Aging Quality of Life and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire

Background: Patient-reported outcomes of the quality of life (QOL) after an open thoracotomy have not been studied. To determine the physical and mental changes in surgical patients is very important for medical staffs. The surgical patient’s satisfaction and overall healthy changes were evaluated by the patient-self assessment questionnaires. Materials and Methods: From July 2007 to April 2008, 26 patients with non-small cell lung cancer (NSCLC) underwent surgical resection. The outcome of the QOL was evaluated by using two kinds of questionnaire surveys from the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the anti-aging QOL assessment (AA-QOL). The EORTC QLQ-C30 consisted of five domains (physical, role, cognitive, emotional, and social functionings) and global QOL. The AA-QOL contained 51 items;30 physical and 21 mental symptoms regarding the elderly and the aging population. The patients replied to the two questionnaires at two different times, i.e., at pre-surgery (baseline) and at post-surgery (2 weeks after the operation). The obtained data of these scores were averaged and compared between the two points of the pre-surgery and post-surgery. Results: Regarding the outcomes of the EORTC QLQ-C30, the physical and social functioning became significantly worse after the surgery. In contrast, the global QOL significantly became better after the surgery. For the symptom at post-surgery, three of which were “nausea and vomiting”, “pain”, and “appetite loss”, became significantly worse compared to those at pre-surgery. Regarding the outcomes of the AA-QOL, the physical symptoms (muscular pain/stiffness, palpitations, dyspnea, no feeling of good health, anorexia, and coughing and sputum) became significantly worse after the surgery. Regarding the mental symptoms, there were no significant differences. Conclusions: Regarding the outcomes based on the changes in the QOL after surgery, the physical symptoms became worse compared to the mental symptoms. To clarify the perioperative healthy changes of the QOL reported by patients with lung cancers is very important for multidisciplinary teamwork, which should play a role in providing the appropriate care and treatment and useful information for a preoperative patient’s decision making of receiving surgical treatment.

A comparative study of two methods for establishing a chronic non‑bacterial prostatitis model in rats‑

Objective:To compare the biological characteristics and stability of the chronic non-bacterial prostatitis(CNP)model in rats induced by the depot combined with estrogen induction method and the autoimmune response induction method.Methods:The CNP rat model was prepared using the depot combined with 17β-estradiol induction method in the depot hormone group and three concentrations of prostate protein homogenate at 40 mg/mL,20 mg/mL and 10 mg/mL in the autoimmune group,respectively.The degree of prostate tissue damage was evaluated by pathology(HE staining),and the immunoturbidimetric method was used to evaluate the contents of immunoglobulins IgA,IgM and IgG.ELISA was used to evaluate interleukin-1β(IL-1β),interleukin-10(IL-10),tumor necrosis factor-α(TNF-α)and high-sensitivity-C-reactive protein(hs-CRP),and electrochemiluminescence was used to evaluate the expression level of testosterone(T),and the two model methods were compared.Results:Compared with the sham-operated group,the body mass of rats in both models was significantly lower in the depot hormone group and autoimmune group before extraction(P<0.01,P<0.01),and histopathology of the prostate in both models showed destruction of glandular structure and a significant increase in inflammatory cells.Compared with the depot hormone group and the autoimmune group,the histopathological changes and inflammatory pathological scores of prostate and the contents of immune indexes IgA,IgM and IgG were significantly different in the depot hormone group(P<0.05,P<0.05,P<0.05),and the levels of IL-1β,IL-10,TNF-α,hs-CRP and T were significantly changed in the autoimmune group(P<0.01).The comparison between the high,medium and low dose groups of the autoimmune group,in which the pathological changes in the medium dose of the autoimmune group were slightly better than the other two groups between the groups,but the changes in IL-1β,IL-10,TNF-α,hs-CRP,and T in the low dose of the autoimmune group were the most significant(P<0.05).Conclusion:The pathological tissues of the chronic non-bacterial prostatitis model established by the depot combined with estrogen induction method and the autoimmune response induction method both showed significant changes,and the comprehensive indexes indicated that the depot combined with estrogen induction method was a more appropriate modeling choice.

Analysis of Prognostic Factors for Surgery after Neo-adjuvant Therapy for Stage Ⅲ Non-small Cell Lung Cancer

In order to explore the possibility to predict the risk factors for postoperative complications and survival time, the clinical data of 152 patients （including 116 males and 36 females） who had undergone neo-adjuvant therapy and surgery for stage IIIA and B non-small cell lung cancer （NSCLC） were retrospectively analyzed. Demographic data, preoperative functional parameters, staging, induction regimen （chemotherapy alone or associated with radiotherapy）, associated disorders, and data about operation were collected. Chi-square test and multivariate analysis fitting the unconditional logistic regression model were performed to identify predictors of postoperative complications, while Kaplan-Meier and multivariate Cox proportional hazard model were employed to identify predictors of survival time, respectively. The univariate analysis demonstrated that forced expiratory volume in 1 second predicted percent （FEV1%, P=0.040） and associated disorders （P=0.020） were the predictive factors of complications, but multivariate analysis found no independence factors （P〉0.05） of it. Univariate Kaplan-Meier analysis showed that stage （P=0.050） and pneumonectomy （P=0.018） affected the survival time. However, multivariate Cox proportional hazard model analysis demonstrated that only pneumonectomy （P=0.026） was associated with a decreased survival time, but no differences between right and left pneumonectomy were found. The results suggest that the risk factor for postoperative complications is acceptable, and pneumonectomy is associated with increased mortality, which should be performed only in stage Ⅲ NSCLC patients.

Do Patients with Asymptomatic Congenital Complete Heart Block Require a Pacemaker for Non-Cardiac Surgery?

The appropriate preparation of the patient with asymptomatic congenital complete heart block (CCHB) and a narrow QRS complex for elective non-cardiac surgery is controversial. Prophylactic temporary pacemaker insertion is associated with well-defined risks, and less invasive techniques exist to treat transient, hemodynamically significant intraoperative brady-arrhythmias. The present case report details the performance of general anesthesia for arthroscopic knee surgery in an adult patient with this condition without a pacemaker. Documentation of preoperative chronotropic competence with isoproterenol may be of value in deciding whether to proceed without temporary pacing capability in this setting.
