The precise anatomical division of liver segments is the foundation of liver surgery, while the anatomical division of the S9 segment of liver is a further precise division of the caudate lobe of the liver. This article retrospectively analyzed and summarized the precise minimally invasive ablation and follow-up results of four representative lesions of the S9 segment of liver, including primary liver cancer, recurrent liver cancer, metastatic liver cancer, and focal liver hyperplasia, treated at Affiliated Dongguan Hospital of Southern Medical University. The aim of this study is to explore the minimally invasive ablation effect of lesions located at the S9 segment of liver under CT guidance.
Radiofrequency ablation for hepatic hemangioma is safe and effective, and can obtain the same curative effect as traditional surgical resection. For hepatic hemangiomas with large volume, abundant arterial blood supply and long ablation time, systemic inflammatory response syndrome (SIRS) often occurs after radiofrequency ablation, which can lead to injury or dysfunction of important organs. This paper systematically summarizes the mechanism, prevention and treatment of SIRS after radiofrequency ablation of hepatic hemangioma, so as to provide reference for improving the safety of radiofrequency ablation of hepatic hemangioma.
【Abstract】ObjectiveTo investigate the effect of high intensity focused ultrasound (HIFU) on the immunity of patients with advanced primary liver cancer (PLC). MethodsForty cases of PLC admitted to our institution from Mar. 2003 to Dec. 2003 were included in this study. Patients were divided into 2 groups and received either HIFU or radiofrequency ablation (RFA) treatment randomly. CD3, CD4, CD8, CD4/CD8, NK, IL-2, TNF were chosen to assess the immune status before and after treatment. The results were compared statistically. ResultsThe survival rate after HIFU was 80.0%, 61.1%, 42.9%, 33.3% at 3 months, 6 months, 9 months and 1 year respectively, which was similar to that after RFA treatment. The changes of immunity parameters of CD3, CD4, CD8, CD4/CD8, NK, IL-2 and TNF were not significant after HIFU treatment. In addition, the differences of those parameters between HIFU group and RFA group were insignificant. ConclusionThere are no detrimental effects on immunity in the early period after HIFU treatment.
Malignant airway stenosis generally refers to airway lumen stenosis caused by various primary and metastatic malignant tumors and restricted airflow, which can be manifested as dyspnea to varying degrees or even asphyxia and death. It seriously affects the quality of life of patients with airway stenosis. With the continuous development of bronchoscope interventional techniques, various interventional therapies such as ablation, dilation and stent implantation can be used to reventilate the airway. Among them, ablation treatment is the most commonly used method. The methods of ablation treatment include cold, heat, photodynamic, local chemoradiotherapy, etc. This article will review the new applications of various methods used in the ablation treatment of malignant airway stenosis progress.
Objective To investigate the clinical applicationand curative effect of isoionic microtrauma arthroscope on treatment of knee arthropathy. Methods From May 2003 to November 2004, 52 cases of knee joint injury were cured by using isoionic microtrauma arthroscope, including 30 cases ofknee osteoarthritis, 10 cases of meniscus injury, 5 cases of kneecap dislocation, 5 cases of laxity of anterior cruciate ligation and 2 cases of rheumatoid arthritis. In accordance with Lysholm criterion for knee joint function, the scores were 35.5±4.9 before operation. Results All of these patients were followed up for 2-17 months. The scores of knee joint function was 86.4±5.3 after operation, and there was significant difference (Plt;0.001). Conclusion Isoionic microtrauma arthroscope is characterized by low-temperature hemoagglutination, crimpling,boiling, cutting and hemostasia, which makes kneejoint arthroscope operation easier-to-do, miner histological scathe and lighter side effect; so it is favourable for functional recovery and its curative effect is satisfactory.
Objective To analyze the current status and hotspots of surgical transmural ablation of atrial fibrillation using CiteSpace and VOSviewer. MethodsThe Web of Science Core Collection database was used as the data source. The CiteSpace 5.8.R3 and VOSviewer software were used to analyze the related studies on surgical transmural ablation of atrial fibrillation about the authors, countries/institutions, literature co-citation and keywords. Results A total of 109 articles were enrolled. Damiano RJ was the most prolific researcher, while Cox JL was the author with the highest number of citations. The United States was the leading country in this research field. The University of Washington was an important institution in the study of atrial fibrillation transmural ablation. The main hotpots were the effectiveness of surgical ablation, especially Cox-maze procedure, selection of the energy source of surgical ablation, combination of surgical and catheter ablations, and pulmonary vein isolation. ConclusionThis study visualizes the current research status of surgical ablation of atrial fibrillation. How to improve the effectiveness and transmurality of surgical ablation is a hot research topic in the surgical treatment of atrial fibrillation. The combination of electrophysiology mapping and surgical ablation may be the development direction in the surgical treatment of atrial fibrillation.
Objective To analyze the common post-operative complications of microwave ablation in situ in the treatment of bone tumors and the prevention and control strategies. Methods Between March 2009 and July 2012, 73 cases of bone tumors were treated with microwave ablation in situ, of which 54 cases met the inclusion criteria. There were 31 males and 23 females with a median age of 27 years (range, 9-74 years), including 37 malignant tumors and 17 benign tumors. In 49 primary bone tumors, 17 cases were in stage 3, 13 in stage IIA, and 19 in stage IIB according to Enneking grading system. The postoperative complications, managements, and outcomes in patients were analyzed. Results After operation, 54 patients were followed up 12-40 months (mean, 24 months). Seven kinds of complications occurred in 21 patients (38.9%) with 3 cases suffered from more than one, including pathologic fracture in 4 cases (7.4%), deep infection in 2 cases (3.7%), nerve injury in 7 cases (13.0%), deep vein thrombosis of the lower extremity in 1 case (1.9%), medial collateral ligament heat injury of the knee in 1 case (1.9%), hematoma in 2 cases (3.7%), and fat liquefaction of incision and flap necrosis in 8 cases (14.8%). Conclusion Pathologic fracture is the primary complication which results in a second surgery. Deep infection is the main complication that often leads to failure of the limb salvage. Nerve injury and poor wound healing are the most common complications. Good control of microwave temperature is the key to successful operation, and the related preventive strategies could reduce complications.
