  • 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.

  • 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.

  • Application Progress of MRI in Assessment of Rectal Cancer Before Surgery

    Objective To summarize the research progress of MRI in the assessment of rectal cancer before surgery. Methods Literatures about the recent studies on the research progress of MRI in the assessment of rectal cancer before surgery were reviewed according to the results searched from Pubmed, CNKI, and WanFang database. Results Preoperative staging, circumferential resection margin, and extramural vascular invasion were closely related to the prognosis of rectal cancer patients, MRI could provide a good assessment of preoperative staging, circumferential resection margin, and extramural vascular invasion for rectal cancer patients, but it still had some deficiencies which needed further studies. Conclusion Application of MRI in the assessment of preoperative staging, circumferential resection margin, and extramural vascular invasion before surgery, is conducive to the development of the most appropriate treatment options for patients with rectal cancer.

  • 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.

  • Research Progress of Preoperative Predictors of New Onset Atrial Fibrillation after Coronary Artery Bypass Grafting

    Atrial fibrillation is one of the most common complications after coronary artery bypass grafting (CABG), with the occurrence rate of approximate 30%, which leads to hemodynamic instability, reduces survival rate, prolongs hospitalization, and increases patients' economic burden. Previous numerous studies have shown lots of preoperative, intra-operative and postoperative factors can predict the occurrence of new onset atrial fibrillation after CABG. If we can identify the specific patients at high risk for developing atrial fibrillation before operation, we may prevent atrial fibrillation more effectively, avoiding unnecessary prophylactic treatment and its risk. This review only focuses on research progress of preoperative predictors.

  • Preoperative Assessment of Vascular Invasion in Pancreatic CancerValue of CT

    Objective To probe CT grading criteria of vascular invasion in pancreatic cancer. Methods Retrieved articles in CNKI and PubMed about value of CT in preoperative assessment of vascular invasion in pancreatic cancer last ten years. Results Multislice helical CT is considered the best imaging method to assess the invaded peripancreatic vessels in pancreatic cancer. There are different CT criteria of vascular invasion in pancreatic cancer based on extension of hypodense tumor and its relation to blood vessels, on the degree of circumferential contiguity of tumor to vessel, on the degree of lumen stenosis, and on the degree of contiguity between tumor and vessels combined vascular caliber. Conclusion CT grading criteria are not uniform, each one has defects.

  • 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.

  • Observation of the clinical effect of preoperative exercise intervention on posterior lateral approach total hip replacement

    Objective To investigate and explore the clinical effect of preoperative exercise intervention on total hip arthroplasty. Methods Seventy-three patients who underwent primary unilateral total hip replacement (THR) in the Orthopedics Department, the Second Hospital of Jilin University between March 2017 and January 2018 were divided into 2 groups: treatment group (n=37) and control group (n=36). Patients in treatment group received exercise intervention and routine education since 4 weeks before surgery; the control group just received routine education before surgery and both groups underwent the same routine rehabilitation training. The Visual Analogue Scale (VAS) was evaluated and compared separately between the two groups at 4 weeks before surgery (T0), 1 day before surgery (T1), before discharge (T2), 1 month after discharge (T3), and 3 months after discharge (T4). The results of Hip Harris score and Time Up and Go test (TUG) were evaluated and compared separately between the two groups at T0, T1, T3 and T4. Results Time of TUG of the treatment group and the control group at T1, T3 and T4 were (14.59±3.15) vs. (16.31±3.31) s, (13.61±2.76)vs. (15.25±3.08) s, (12.49±2.37)vs. (14.22±2.65) s, respectively, and the differences between the two groups at T1, T3 and T4 were all statistically significant (P<0.05). In terms of VAS and Harris scores, both groups showed significant improvement after surgery at different time nodes (P<0.05), but the differences between the two groups was not statistically significant (P>0.05). Conclusion Preoperative exercise intervention can effectively improve the walking ability of THR patients and reduce the risk of falls after discharge, but it did not reduce postoperative pain or improve postoperative hip Harris score after discharge.

  • The Role of Preoperative Evaluation of Serum Tumor Markers in Gastric Cancer

    ObjectiveTo study the preoperative evaluation value of serum tumor markers (CA72-4, CEA, CA199 and CA125) in patients with gastric cancer. MethodsSerum levels of tumor markers (CA72-4, CEA, CA199 and CA125) and clinical pathological data of 70 patients with gastric cancer before operation who underwent surgical treatment in the Gastrointestinal Surgery Department of Second Affiliated Hospital of Kunming Medical University in June 2013 to 2014 June were retrospectively analyzed. ResultsThere were some connection between the concentration of the serum CA72-4 and the tumor diameter, TNM staging, invasion depth, and the number of lymph node metastasis (P < 0.05), between CA199 and tumor size, TNM staging, and invasion depth (P < 0.05), between CEA, CA125 and tumor diameter, TNM staging and distant metastasis (P < 0.05), but the CA72-4, CA72-4, CEA and CA125 had nothing to do with patient' age and gender. ConclusionThe serum tumor markers of CA724, CEA, CA199, and CA125 have clinical application value in preoperative evaluation of gastric cancer.

  • Prophylactic Use of Intra-aortic Balloon Pump Counterpulsation before High Risk Coronary Artery Bypass Grafting Patients: A Meta-analysis

    ObjectiveTo systematically review the efficacy and safety of prophylactic use of intra-aortic balloon pump counterpulsation (IABP) before coronary artery bypass grafting (CABG) in high risk patients. MethodsDatabases including The Cochrane Library (Issue 2, 2014), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were electronically searched from inception to July 2014, to collect randomized controlled trials (RCTs) and cohort studies about prophylactic use of IABP before CABG in high risk patients. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software. ResultsA total of 6 RCTs and 6 cohort studies involving 1 359 patients were included, of which 633 prophylactically used IABP before CABG (the IABP group) and 736 didn't prophylactically use IABP before CABG (the control group). The results of meta-analysis showed that: compared with the control group, prophylactic use of IABP could significantly reduce perioperative mortality (RCT: OR=0.15, 95%CI 0.06 to 0.38, P<0.000 1; cohort study: OR=0.36, 95%CI 0.19 to 0.67, P=0.001) and postoperative LCOS (RCT: OR=0.23, 95%CI 0.12 to 0.43, P<0.000 01; cohort study: OR=0.21, 95%CI 0.10 to 0.43, P<0.000 1); there was no significant difference between two groups in incidence rate of postoperative myocardial infarction (MI) (RCT: OR=0.34, 95%CI 0.10 to 1.11, P=0.07; cohort study: OR=0.56, 95%CI 0.26 to 1.24, P=0.15); the results of combined analyses of RCTs showed that, prophylactic use of IABP could significantly reduce postoperative ICU stay (MD=-42.94, 95%CI -56.11 to -29.76, P<0.000 01) and postoperative hospital stay (MD=-3.83, 95%CI-5.82 to -1.85, P=0.0002), but these differences were not found in the results of combined analyses of cohort studies (MD=-4.68, 95%CI 20.69 to 11.33, P=0.57; MD=-0.77, 95%CI -1.80 to 0.26, P=0.14). ConclusionProphylactic use of IABP before CABG in high risk patients can significantly reduce the perioperative mortality, postoperative LCOS and the length of ICU stay, however it cannot reduce postoperative MI. Due to the limited quantity and quality of included studies, the above conclusions still need to be verified by more high quality studies.
