ObjectiveTo investigate the clinical value of preoperative biliary drainage in patients with malignant obstructive jaundice and its influence on postoperative complications.MethodsThis study retrospectively analyzed patients from June 2006 to June 2018 at Department of Hepatobiliary Surgery of Gaozhou People’s Hospital, Guangdong Medical University, who had underwent pancreaticoduodenal surgery. In this study, bilirubin was divided into bilirubin normal group and bilirubin abnormal group according to the level of bilirubin, then the bilirubin abnormal group was divided into non-drainage group and drainage group. The main observation indexes were the incidence of complications and their severity.ResultsThere was no difference in intraoperative blood loss, operative time, and postoperative hospitalization among the three groups (P>0.05), but there was significant difference among the three groups on incidence of bile leakage, pulmonary infection, and the comprehensive complication index (CCI) value (P<0.05). The trend of clotting time, serum albumin, and hemoglobin in the bilirubin normal group, non-drainage group, and drainage group after operation were basically the same. The transaminase was recovered after operation in the bilirubin normal group and the drainage group, which were better than that of the non-drainage group within 7 days .ConclusionsThe preoperative biliary drainage in patients with malignant obstructive jaundice complicated with hyperbilirubinemia, cholangitis, and hepatic dysfunction do not significantly improve the incidence of complications, but could significantly improve the severity of the overall complication.
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.
ObjectiveTo analyze the relation between preoperative staging and surgical decision-making in rectal cancer patients from the West China Colorectal Cancer Database (DACCA) and to identify key factors influencing the selection of surgical approach. MethodsBased on the updated DACCA dataset as of April 24, 2024, the patients with rectal cancer were included. Chi-square tests and logistic regression analyses were performed to evaluate the correlation between preoperative staging [(y)cTNM stage] and the selection of sphincter-preserving surgery or intersphincteric resection (ISR). Additional factors, including age, body mass index (BMI), tumor location, and nutritional score, were assessed for their impact on surgical choices. ResultsA total of 2 733 rectal cancer patients were included. Preoperative (y)cTNM staging distribution was as follows: 23 (0.8%) at stage 0, 388 (14.2%) at stage Ⅰ, 760 (27.8%) at stage Ⅱ, 873 (31.9%) at stage Ⅲ, and 689 (25.2%) at stage Ⅳ. The preoperative stage Ⅱ–Ⅳ were the independent risk factors for both the choices of sphincter-preserving surgery and ISR [stage Ⅱ: sphincter-preserving surgery: OR(95%CI)=13.634 (4.952, 37.540), P<0.001; ISR: OR (95%CI)=3.097 (2.108, 4.551), P<0.001. stage Ⅲ: sphincter-preserving surgery: OR (95%CI)=14.677 (5.339, 40.345), P<0.001; ISR: OR (95%CI)=2.985 (2.042, 4.363), P<0.001. stage Ⅳ: OR (95%CI)=25.653 (9.320, 70.610), P<0.001; ISR: OR (95%CI)=4.445 (3.015, 6.555), P<0.001]. The low/ultra-low tumor location was an independent risk factor for choice of sphincter-preserving surgery [OR (95%CI)=2.038 (1.489, 2.791), P<0.001], but which was an independent protective factor for the choice of ISR [OR (95%CI)=0.013 (0.009, 0.019), P<0.001]. ConclusionsResults of this study are consistent with clinical practice, indicating that preoperative staging is the core basis for surgical decision-making in rectal cancer. With the progression of staging, patients are more inclined to choose non-sphincter-preserving and non-ISR procedures. Although low/ultralow tumors pose great challenges for anal preservation, the proportion of ISR selection remains relatively high. The anatomical location of the tumor and nutritional status also significantly affect surgical selection, necessitating comprehensive preoperative evaluation.
摘要:目的: 探讨64排多层螺旋CT(MSCT)和血清淀粉样蛋白A(serum amyloid A protein, SAA)联合术前评估直肠癌在肿瘤分期诊断中的作用。 方法 :纳入经根治术治疗的直肠癌患者通过MSCT扫描进行评估,同时取患者静脉血测量术前SAA水平,行MSCT分期与MSCT和SAA联合分期以比较二者的诊断价值。 结果 :本研究纳入患者121例。MSCT检测T分期的准确度为851%。在评估淋巴结转移方面,MSCT和SAA联合分期的准确度为760%,明显高于MSCT分期(595%, 〖WTBX〗P lt;0001)。MSCT正确判断所有远处转移。同单一的MSCT检测相比,MSCT和SAA联合评估能显著的提高术前TNM分期的准确率(785% vs. 636%,〖WTBX〗P =0011)。 结论 :MSCT联合SAA检测比单一的MSCT检测显著提高了直肠癌术前肿瘤分期和淋巴结转移方面的准确度。这种新的术前评估方法的为肿瘤进展评估和术前治疗决策提供了更加可靠的信息。Abstract: Objective: To determine the role of combinative assessment of 64 multislice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) in preoperative rectal cancer staging. Methods : Enrolled consecutive rectal cancer patients undergoing curative surgery were evaluated by MSCT scan. Meanwhile venous blood specimens were taken to measure preoperative SAA concentration. Both MSCT staging and MSCT plus SAA staging were performed to compare with each other. Results : The study population consisted of 121 patients. The accuracy of T staging was 851% for MSCT. The accuracy in evaluating lymph nodes metastases was 760% for MSCT plus SAA compared with 595% for MSCT alone (〖WTBX〗P lt;0001). All the distant metastases were correctly detected by MSCT. The method combining MSCT with SAA led to significant improvement on preoperative TNM staging compared with MSCT alone (785% vs. 636%, 〖WTBX〗P =0011). Conclusion : MSCT plus SAA showed greater accuracy than MSCT alone in rectal cancer staging and lymph node metastases. This novel strategy of preoperative evaluation appears to provide more accurate information on tumor progression and preoperative therapy decisionmaking.
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.
Surgery is an essential method of comprehensive treatment for lung cancer, but it also impairs patients’ cardiopulmonary function. A subset of patients who undergo surgery may suffer from postoperative complications, and even death. Preoperative pulmonary rehabilitation is a part of enhanced recovery after surgery, and can improve patients' cardiopulmonary function, reduce postoperative complication rate and shorten hospital stay. It has been already demonstrated a great value in lung cancer surgery. In this review, we summarized the three important components of preoperative pulmonary rehabilitation, including smoking cessation, chest physical therapy, and preoperative exercise training. Moreover, this review outlined the development of pulmonary rehabilitation for lung malignancies, aiming to promote its application and standardization.
Partial or complete blockage of the bile outflow tract by extrahepatic cholangiocarcinoma often leads to jaundice, which not only causes skin itching in patients, but also destroys the body environment through a series of pathophysiological processes, reduces the surgical tolerance of patients with resectable tumors, and affects the prognosis. Preoperative jaundice reduction can reduce jaundice and relieve biliary obstruction, but the various complications that follow will also adversely affect the treatment. This article elaborates on the disadvantages of different methods for jaundice reduction, the indications for preoperative jaundice reduction, the jaundice reduction options for different types of extrahepatic cholangiocarcinoma, the complications and treatment methods of preoperative jaundice reduction for extrahepatic cholangiocarcinoma, aiming to provide a reference for clinicians, so that patients can better benefit from preoperative jaundice reduction.
Objective To introduce a simple preoperative risk score for esophageal cancer (PRSEC) and its relationship with the prognosis of patients who underwent resection of esophageal carcinoma. Methods We retrospectively analyzed the clinical data of 498 patients receiving resection of esophageal carcinoma between 2005 and 2015 in our hospital. They were divided into three groups (PRSEC1, PRSEC2 and PRSEC3 groups) according to the results of PRSEC (revised cardiac risk index, model for end-stage liver disease score and pulmonary function test). Their overall survival (OS) and disease-free survival (DFS) were measured to find the relationship between the PRSEC and prognosis of patients. Results The mortality, morbidity, DFS and OS were correlative with the PRSEC. Therefore the PRSEC can be used to predict the short-term outcome. The patients with score 2 or 3 had higher risk of mortality and morbidity than those with score 1. In addition, the DFS and OS of patients with higher score were shorter (P<0.001). Conclusion The PRSEC is easy and efficient and can predict the morbidity, mortality, and long-term outcomes for the patients with resection of esophageal carcinoma.
