Objective To assess the clinical value of preoperative localization coupled with computed tomography (CT) three-dimensional reconstruction in pulmonary nodule-centered uniportal thoracoscopic combined subsegmental/segmental resection. Methods The clinical data of 30 patients of combined subsegmental/segmental resection in our hospital from December 2019 to October 2021 were retrospectively collected. There were 19 males and 11 females with the mean age of 56.4 (32.0-71.0) years. The pulmonary nodules were located by CT-guided injection of glue before operation. The three-dimensional reconstruction image and operation planning were carried out by Mimics 21.0 software. ResultsThe operations were all successfully performed, and there was no conversion to open thoracotomy or lobectomy. The mean tumor diameter was 11.6±3.5 mm, the mean distance between the nodule and the visceral pleura was 13.6±5.6 mm, the mean width of the actual cutting edge was 25.0±6.5 mm, the mean operation time was 110.2±23.8 min, the mean number of lymph node dissection stations was 6.5±2.4, the mean amount of intraoperative bleeding was 50.8±20.3 mL, the mean retention time of thoracic catheter was 3.2±1.1 d, and the mean postoperative hospital stay was 4.5±1.7 d. There was 1 patient of subcutaneous emphysema, 1 patient of atrial fibrillation and 1 patient of blood in sputum. Conclusion Preoperative CT-guided injection of medical glue combined with CT three-dimensional reconstruction of pulmonary bronchus and blood vessels is safe and feasible in pulmonary nodule-centered uniportal thoracoscopic combined subsegmental/segmental resection, which ensures the surgical margin and reserves lung tissues.
Objective To determine the accuracy of endorectal ultrasonography (ERUS) in preoperative staging of rectal cancer and investigate the limitations and pitfalls of ERUS. Methods Ninety-four patients with rectal cancer were examined preoperatively by ERUS between September 2008 and November 2009 in this hospital. The size, shape, echo pattern, infiltration depth, and extra-rectal invasion of lesions were observed. The results of ERUS staging were compared with histopathology findings of the resected specimens. Results The overall accuracy of ERUS in T staging was 63.8% (60/94). The accuracies of ERUS for pT1, pT2, pT3, and pT4 tumor were 87.2% (82/94), 76.6% (72/94), 76.6% (72/94), and 97.9% (92/94), respectively. The sensitivity, specificity, and accuracy of ERUS for advanced rectal cancer (pT3+pT4) were 70.8% (34/48), 78.3% (36/46), and 74.5% (70/94), respectively. The sensitivity, specificity, and accuracy of ERUS in lymph node metastasis were 75.0% (42/56), 42.1% (16/38), and 61.7% (58/94), respectively. There was no significant difference of accuracy among various tumor locations above anocutaneous line (P＝0.495). The accuracy of ERUS for T staging improved with experience, the T staging accuracy improved from 40.0% after assessment of 30 cases to 81.3% after 94 cases were examined (P＝0.026). Conclusions The ERUS provides a good accuracy rate for assessment of the depth of tumor invasion and lymph node metastasis of rectal cancer, and has become an important imaging tool for preoperative staging rectal cancer. The operator experience, peritumoral inflammation mainly influences the accuracy of ERUS.
ObjectiveTo evaluate roles and advantages of magnetic resonance imaging (MRI) and compute.tomography (CT) in preoperative assessment for hepatic alveolar echinococcosis. MethodMRI and CT scan imaging data of 60 patients with hepatic alveolar echinococcosis underwent radical surgery were retrospectively analyzed. ResultsMRI scanning could accurately identify the peripheral zone and marginal zone of hepatic alveolar echinococcosis lesions, and CT could not accurately show the above structures. In assessment of anatomic relation between vascular and lesions, MRI findings of 52 cases were in full compliance with corresponding intraoperative findings, and 8 cases were partial compliant. However, CT findings of 35 cases were in full compliance with corresponding intraoperative findings, 13 cases were partial compliant, and 12 cases were not compliant at all. In assessment of anatomic relation between biliary and lesions, MRCP could clearly show the bile duct, bile duct stenosis location and degree; CT scanning could only show widened bile duct, but could not accurately judge bile duct dilatation. ConclusionsMRI exerts some obvious advantages in preoperative evaluation of hepatic alveolar echinococcosis, and could accurately find relation between lesions and vascular or biliary system. MRI should be used as routine examination for patients with hepatic alveolar echinococcosis.
Objective To investigate the task group’s effectiveness in language evaluation based on the task group's functional Magnetic resonance (fMRI) results’ agreement with the fixation side of the Wada language area. MethodsWe collected 90 patients with intractable epilepsy of 90 patients from December 13, 2018 to January 3, 2020 from the Epilepsy Center of Guangdong 999 Brain Hospital. We used two simple fMRI tasks. Among them, 25 patients completed the Wada experimental examination, and 8 patients completed the electrode implantation and subsequent preoperative language area mapping. Adopt block experimental design, ABBA style presentation, and use AFNI software to process fMRI data, lateralization index calculation, and multiple regression analysis. ResultsfMRI results from 90 patients showed that the results from both the sentence-completion task and the image-naming task were more stable than those from either task. The results were then compared with the results of the “gold standard” Wada test in 25 patients with fMRI-located language dominance in the hemisphere. The results showed that the accuracy of the single task was between 70% and 80%, but the accuracy of the combined results of the two tasks was 93.3%. Conclusions Compared with the results of a single task, the results of multiple fMRI tasks are more stable in the judgment of activation range and language dominance hemisphere. fMRI and Wada language area siding accuracy 93.3%, fMRI task siding valid and replicable.
ObjectiveTo analyze the current situation of day surgery patients’ withdrawal from hospitalization, and put forward reasonable and effective measures and suggestions.MethodsDescriptive statistical analysis and trend chi-square test were conducted on the hospitalization withdrawal rate of day surgery in the Day Surgery Ward of the Second Affiliated Hospital Zhejiang University School of Medicine from 2012 to 2020. The reasons for hospitalization withdrawal and the operation methods of withdrawn cases from 2019 to 2020 were descriptively analyzed.ResultsFrom 2012 to 2020, the hospitalization withdrawal rate of day surgery decreased from 4.48% to 2.19%, with a significant decrease and a linear downward trend (χ2trend=138.500, P<0.001). From 2019 to 2020, patient factor was the most important reason for hospitalization withdrawal of day surgery, accounting for 79.72%; secondly, long waiting time for surgery, abnormal examination results, inadequate preoperative evaluation, medical insurance reimbursement, epidemic situation in 2020 and other reasons had affected the patients’ hospitalization withdrawal of day surgery to varying degrees. Endoscopic lithotripsy accounted for the largest proportion (210 cases, accounting for 20.87%) in the withdrawn procedures from 2019 to 2020, followed by minimally invasive rotary resection for breast lesions (126 cases, accounting for 12.52%).ConclusionImproving preoperative evaluation, strengthening preoperative communication, implementing efficient medical treatment, and shortening the waiting time for surgery can reduce the rate of hospitalization withdrawal of day surgery.
The effects of preoperative selective arterial perfusion chemotherapy (PSAPC) in the treatment of 20 cases of histologically confirmed gastric cancers is reported in which 12 patients were operated on, and a comparison with that of general chemotherapy in 10 cases of gastric cancers (as controls) was made. In the PSAPC group, besides the improvement of clinical symptoms and singns, the cancer cells of lesions in situ and metastatic lymph nodes have different degrees of degeneration and necrosis. This result show significant differences in two group comparison (Plt;O.01). We conclude that the PSAPC has good short-term effect and little side-effect. It can improve the resection rate and radical resection rate, and prevent the iatrogenic metastasis and implantation during operation, and decrease the postoperative recurrence of the patients with gastric cancer.
ObjectiveTo explore the application effect of preoperative health education in patients with glaucoma. MethodsA total of 120 patients with glaucoma who underwent the surgery from February 2013 to December 2014 were randomly divided into control group and observation group, with 60 cases in each. The routine health education was performed on the patients in the control group while the personalized health education (on the basis of adopting the knowledge of the self-designed questionnaire) on the ones in the observation group. The results of Self-rating Anxiety Scale (SAS), Self-rating Depressive Scale (SDS), extent of disease knowledge, and nursing satisfaction were observed. ResultsAfter health education, the scores of SAS and SDS was 29.9±7.6 and 32.0±7.8, respectively in the observation group, which were significantly lower than those in the control group (34.9±7.9 and 35.9±8.3, P<0.05). Awareness of related knowledge and nursing satisfaction were 53 patients (88.3%) and 57 patients (95.0%) in observation group and 49 patients (81.7%) and 53 patients (88.3%) in the control group, (P>0.05). ConclusionPreoperative health education can improve the patients psychology and may reduce the occurrence of complications.
Objective To summarize the current value of neoadjuvant chemotherapy (NAC) for potentially resectable gastric cancer. Methods The recent 5-year literatures searched through the PubMed with the key words: stomach neoplasm, gastric cancer/carcinoma, neoadjuvant therapy/chemotherapy and preoperative therapy/chemotherapy as well as the relevant reports presented in the ASCO Annual Meeting in 2007 and 2008 were analyzed. The present status of NAC for advanced gastric cancer was summarized, the necessity and feasibility were evaluated, and the patients features for selecting, the predictors for response, the mainly existing problems and development trend of NAC were analyzed. Results At present, there were 7 randomized control trails (RCT) published, and among them 3 were phase Ⅲ. It was safe, effective and feasible to most of trails in NAC for gastric cancer. However, it was still little to obtain survival benefit for NAC RCT, and short of randomized trial comparing strict preoperative chemotherapy to surgery alone or perioperative chemotherapy to surgery plus adjuvant chemotherapy. It remained lots of problems such as how to select the appropriate patients, the effective induced regimes and the predicted factors, the evaluated indices for response. Conclusion NAC is a safe, feasible and efficient method to potentially resectable gastric cancer, but strict phase Ⅲ randomized trials are needed. In the future, substantial improvements of treatment outcome will likely depend on the novel drugs and molecular biological targeted therapies.
ObjectiveTo evaluate the prognostic value of preoperative inflammatory indexes in patients with local-advanced esophageal squamous cell carcinoma.MethodsWe retrospectively analyzed the clinical and prognostic data of 150 local-advanced esophageal squamous cell carcinoma patients who were treated by esophagectomy in Guangyuan Central Hospital from July 2014 to July 2015. There were 128 males and 22 females with average age of 62.23±8.48 years. The optimal cutoff value was determined by receiver operation characteristics (ROC) curve analysis. Patients were grouped according to the optimal cutoff values (NLR=3.49, PLR=152.28, MLR=0.36). Log-rank test, and multivariate Cox logistic regression modelling were used to assess the simultaneous influences of prognostic factors for survival outcomes after esophagectomy.ResultsThe patients with higher ratio (NLR>3.49, PLR>152.28, MLR>0.36) had significantly shorter median progression free survival (PFS) and lower postoperative recurrent rate than those of the patients with lower ratio. The stratified analyses found that thelymph node staging and postoperative recurrent rate were positively correlated with the higher ratio. However, the tumor differentiation was negatively correlated with it. In univariate analyses, patients with preoperative NLR>3.49, PLR>152.28 and MLR>0.36 had a poorer prognosis. Furthermore, in multivariate analyses we found MLR>0.36 was also significantly associated with a decreased postoperative recurrent rate (HR=12.945, 95%CI 2.31 to 72.548, P=0.00).ConclusionsThe preoperative NLR, PLR and MLR are useful prognostic markers in patients with stage ⅢA-ⅣA esophageal squamous cell carcinoma who conducted esophagectomy.
ObjectiveTo investigate the negative emotions of patients before cardiac surgery in West China Hospital in order to analyze the related factors.MethodsThe Huaxi emotional-distress index (HEI), a screening tool for mood disorders developed by the Mental Health Center of West China Hospital, was used for preoperative psychological evaluation of 1 968 adult patients hospitalized in cardiac surgery from March 2016 to July 2014. There were 835 males and 1 133 females at age of 49±13 years.Results Fifty-one patients (2.6%) had negative emotions, among whom 6 patients were screened for suicide risk. After intervention, none of them had serious consequences caused by adverse emotions, such as automatic discharge from hospital, avoidance of surgery and suicide.ConclusionThis study found that most of the cardiac surgery patients in West China Hospital have good psychological status before surgery, and a few suffered from negative emotions. “Huaxi emotional-distress index” is simple, effective and worth promoting.
