  • CLINICO-PATHOLOGICAL STUDY OF PREOPERATIVE SELECTIVE ARTERIAL PERFUSION CHEMOTHERAPY IN THE TREATMENT OF GASTRIC CANCERS

    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.

  • Application Value of CT in Preoperative Diagnosis of Omental Torsion

    ObjectiveTo summarize the clinical features and imaging features of CT in the omental torsion, and in order to reduce the misdiagnosis and missed diagnosis rate of imaging features. MethodsThe data of 16 cases of omental torsion (secondary 15 cases, primary 1 case) and 286 cases of acute appendicitis (eliminated the subhepatic and retroperitoneal ectopic appendix) in our hospital from 1998 to 2014 were retrospectively analyzed. ResultsEleven cases of omental torsion suffered from the shifting pain in right lower quadrant. No obvious shifting abdominal pain was observed in other 4 cases whose main manifestations were abdominal tenderness and rebound tenderness around umbilicus. The patient of the remaining 1 case had enclosed mass in the area of left groin with pain and suffered from continuous periumbilical pain. Abdominal spiral CT examination was performed in 16 patients before operation. Increased signal intensity of globular soft tissue, which deviating from McBurney's point, was found at level of distal umbilicus by preoperative spiral CT in 13 cases. One case of omental torsion associated with ncarcerated inguinal hernia was missed. ConclusionsOmental torsion manifests chiefly shifting pain in right lower quadrant, abdominal tenderness, and rebound tenderness around umbilicus. It is easily confused with appendicitis. Abdominal spiral CT should be chosen as a preferred means in preoperative diagnosis of omental torsion.

  • Analysis of current situation of day surgery patients’ withdrawal from hospitalization

    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.

  • Stereotactic EEG-based cortical electrical stimulation in the preoperative evaluation of epilepsy

    Epilepsy is one of the most common neurological disorders, and surgical intervention is usually used for drug-resistant focal epilepsy. Cortical electrical stimulation is widely used in preoperative evaluation of epilepsy to explore the anatomical-clinical electrical correlations between epileptogenic and functional networks through electrical stimulation, and the functional brain maps produced by cortical electrical stimulation depict areas of the functional cortex at an individual level, identifying the functional cortex with greater precision, as well as helping to establish epilepsy network, enabling more precise localization of seizure zones and providing a more accurate localization for surgical resection. Electrical cortical stimulation has become a standard technique for the preoperative assessment of brain region function in brain surgery. It is an indispensable part of preoperative evaluation.The main types of functional mapping by electrical stimulation include stereoelectroencephalography (SEEG) and subdural electrode (SDE), SEEG-guided cortical electrical stimulation is gradually becoming more mainstream compared to subdural electrodes, and is increasingly valuable and important as a preoperative evaluation of epilepsy. It is increasingly demonstrating its value and importance because it avoids craniotomy, takes less time for surgery, has fewer associated complications and infections, and can explore deep lesions, increasing the understanding of human functional neuroanatomy and enabling more precise localization of seizure zones.This article reviews the history of the development of cortical electrical stimulation technology, the intrinsic mechanisms, the value of the application of SEEG, and also provides a comprehensive comparison between SEEG and SDE, despite the irreplaceable advantages of SEEG, attention should be paid to the unresolved clinical and scientific issues of SEEG, and the establishment of a consensus-based clinical guideline, as the application of this technology will be more widely used in both clinical and scientific work.

  • Efficacy of dyclonine and lidocaine for preparation pirior to gastroscopy: a meta-analysis

    ObjectivesTo systematically review the efficacy of dyclonine and lidocaine for preparation before gastroscopy.MethodsPubMed, CNKI, CBM, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) of dyclonine vs. lidocaine for preparation before gastroscopy from inception to December 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 11 RCTs were included. The results of meta-analysis showed that: dyclonine could improve anesthetic effect (RR=1.38, 95%CI 1.31 to 1.47, P<0.000 01), and was more capable to remove bubble (RR=1.40, 95%CI 1.28 to 1.52,P<0.000 01), and had superior textures (RR=1.43, 95%CI 1.18 to 1.74,P=0.000 3).ConclusionsOral dyclonine can improve the visual definition of gastric mucosa and anesthetic effect, and has superior textures. Thus, dyclonine can be regarded as a recommended option prior to gastroscopy. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.

  • Analysis on Effect of Neoadjuvant Chemotherapy of Different Differentiated Grades of Locally Advanced Gastric Cancer

    ObjectiveTo evaluate the influence of pathological differentiation in the effect of preoperative chemo-therapy for patients with locally advanced gastric cancer (LAGC). MethodsThirty-two patients with LAGA received preoperative chemotherapy with oxaliplatin and capecitabine (XELOX regimen).According to the pathological examina-tion, patients were classified into better (well and moderate, 16 cases) and poorly (16 cases) differentiated groups, and the clinical response rate, type of gastrectomy, and negative tumor residual rate were compared between the two groups.Morphological changes and toxic reactions were monitored after chemotherapy. ResultsThe results showed that the clinical response rate in the better differentiated group was significantly higher than that in the poorly differentiated group (100% vs.6.4%, P=0.000).The partial gastrectomy rate in the better differentiated group was significantly higher than that in the poorly differentiated group (87.5% vs.25.0%, P=0.000).A significant shrinking of tumor size and necrosis of tumor tissues caused by chemotherapy could be observed. ConclusionThe better differentiated group with locally advanced gastric cancer is suitable for preoperative chemotherapy with XELOX regimen, and as a result of effective preoperative chemotherapy, much more gastric tissue can be preserved for better differentiated group.

  • Application of preoperative localization coupled with CT three-dimensional reconstruction in pulmonary nodule-centered uniportal thoracoscopic combined subsegmental/segmental resection

    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.

  • Analysis of preoperative left ventricular dysfunction and perioperative complications in coronary artery bypass grafting: A case control study

    Objective To identify the relationship between preoperative left ventricular dysfunction and perioperative risk factors in coronary artery bypass grafting (CABG). Methods The clinical data of 192 patients who underwent CABG from November 2015 to October 2016 were analyzed retrospectively. The patients were divided into three groups by preoperative left ventricular ejection fraction (LVEF) in echocardiography: a serious left ventricular dysfunction group (LVEF≤35%, 23 patients, 15 males and 8 females at age of 63.91±5.36 years), a moderate left ventricular dysfunction group (35%<LVEF<50%, 24 patients, 20 males and 4 females at age of 66.29±6.03 years) and a normal left ventricular function group (LVEF≥50%, 145 patients, 86 males and 59 females at age of 66.60±6.41 years). Results The overall mortality was 4.16% (8/192), 17.39% (4/23) in patients with LVEF≤35% and 2.76% (4/145) in those with LVEF≥50%. Preoperative LVEF≤35%, hypoxia, assisted circulation, acute kidney injury (AKI) and postoperative continuous renal replacement therapy (CRRT) were risk factors of perioperative mortality in coronary artery surgery. LVEF≤35% and CRRT were independent preditors of mortality. There were significant differences in mortality and postoperative complications between the serious left ventricular dysfunction group and other two groups. Conclusion Postoperative mortality and complications are obviously serious in the patients with LVEF≤35%. We should pay more attention to preoperative risk factors. Postoperative individual manipulation, intra-aortic balloon pump and CRRT can enhance survival of those patients.

  • Preoperative inflammatory indexes are useful predictors of postoperative survival in patients with local-advanced esophageal squamous cell carcinoma

    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.
