Abstract： Currently, there are two significant tendencies in the advancement and progress of video-assisted thoracoscopic surgery（VATS）, firstly, the widening surgical indications for VATS techniques, and secondly, the use of single-port VATS which is less invasive and more cosmetic. This article focuses in particular on four aspects of single-port VATS, including；（1）the individualized incision approach and its characteristics of single-port VATS；（2）single-port VATS for the treatment of pneumothorax and the development of related techniques and equipment；（3）single-port VATS for the diagnosis and treatment of thoracic diseases such as lung lobectomy；（4）the advantages and disadvantages of single-port VATS in clinical practice.
Abstract: Objective To summarize the clinical experiences of treatment of pulmonary artery dissection, in order to improve the diagnosis and treatment of the disease. Methods We retrospectively analyzed the clinical data of 4 patients including 3 males and 1 female with pulmonary artery dissection who were treated in Fu Wai Hospital between October 1996 and May 2009. Their age ranged from 17 to 45 years with an average age of 31 years. One patient with pulmonary artery dissection with aortic root aneurysm and chronic type Ⅱ aortic dissection was treated with Bentall’s surgery, total arch replacement and pulmonary artery angioplasty under deep hypothermic circulatory arrest. One patient with pulmonary artery dissection with patent ductus arteriosus (PDA) and severe pulmonary hypertension after a failed PDA transcatheter closure was treated with conservative strategy. For the one patient with pulmonary artery dissection with ventricular septal defect (VSD) and severe pulmonary arterial hypertension, VSD was repaired under cardiopulmonary bypass while left pulmonary artery dissection was left untreated. And conservative treatment was carried out for another patient with pulmonary artery dissection with VSD, PDA and Eisenmenger’s syndrome. Results Three patients recovered and 1 patient died of acute pericardial tamponade due to rupture of the dissection within 60 hours after onset of dissection. Followup was done in 3 cases with 1 lost. The followup time was 3 months and 4 years respectively. The New York Heart Association was class Ⅰ and Ⅱ. Conclusion Dissection of the pulmonary artery is a rare disease with a tendency of rupture and bad prognosis. Symptoms of pulmonary artery dissection are nonspecific, which can cause missed diagnosis. In patients with chronic pulmonary hypertension, the sudden seizure of chest pain, exertional dyspnea, and cyanosis, or worsened hemodynamics and cardiac shock may indicate pulmonary artery dissection which can be easily detected with echocardiography, CT scan and magnetic resonance imaging. Corrective surgery or conservative treatment can prevent rupture and possible death based on different causes of pulmonary artery dissection.
Objective To study the diagnosis and treatment of the acute medial collateral ligament ruptures of the knee.Methods From August 1998 to August 2003, 87 cases of acute medial collateral ligament ruptures were examined with physical method and MR imaging. Out of them, 35 cases of Ⅰdegree and Ⅱ degree ruptures were treated with non-surgery and 52 cases of Ⅲ degree ruptures were treated surgically. The torn medial collateral ligaments were mended, 21 of which were strengthened with the anterior partial gracilis muscle tendon after the arthroscopy. Results In 35 cases of Ⅰ and Ⅱ degree ruptures, 32 were followed up 13 months on average. According to Lysholm scoring system, the clinical results were classified as excellent or good in 93.7% of the cases. In 52 cases of Ⅲ degree ruptures, 50 were followed up 16 months on average. The excellent or good result was 90%.Conclusion For Ⅰ and Ⅱ degree ruptures, MR imagimg is an important way to definitely- diagnose medial collateral ligament ruptures. Abduction stress test of knee extension shows that the medial direct instability is a main way to definitely diagnose Ⅲ degree ruptures. The results of conservative treatment of Ⅰ degree and Ⅱ degree ruptures are excellent. Surgical therapy are fitfor the cases of Ⅲ degree ruptures.
ObjectiveRecent advancements in the researches on cholangiocarcinoma (CC) related genes methylation in CC were reviewed and the clinical significances of aberrant DNA methylation for the diagnosis and treatment of CC were discussed. MethodsRelevant literatures about the relation between CC-related genes methylation and CC published recently were collected and reviewed. ResultsThe genesis of CC resulted from abnormal expressions of many genes. Many researches had shown that the abnormal methylation of CC-related genes had a close relation with CC. Epigenetic alteration had been acknowledged as an important mechanism contributing to early CC carcinogenesis. ConclusionsAbnormal methylation of CC-related genes is related with CC. The detection of CC-related genes methylation might provide new specific biomarkers for early noninvasive diagnosis of this disease. Using epigenetic agents such as azacytidine to modulate the activities of DNA methyltransferase and reverse the methylation status of CC-related gene might be an attractive strategy for future treatment of CC, which could be combined with conventional therapies.
ObjectiveTo explore the clinical treatment measures and etiology analysis of lower urinary tract and penile foreign bodies. MethodsWe retrospectively analyzed the etiology and diagnosis of 48 cases of lower urinary tract and penile foreign body in the Department of Urology of our hospital between 1993 and 2012. ResultsNine bladder foreign bodies were removed successfully by using cystoscopy; nine were removed through suprapubic cystotomy; urethral foreign bodies in 10 patients were successfully taken out by urethrascope; five foreign bodies were extracted by hand and forceps; rubber bands in 2 patients were cut off under local anesthesia; fretsaw was used to cut through the nested rings in 7 patients; dental drill was used to cut nesting materials in 3 patients; and 3 patients underwent penis skin circumcision overturn stripping ring extraction. No complications after urethral foreign body extraction occurred. ConclusionThe lower urinary tract and penile foreign bodies are easy to diagnose, but patients often conceal the etiology, so the natural history collection is very important in the diagnosis, and doctors should take appropriate methods to remove the foreign body after the diagnosis is confirmed.
Pulmonary contusion is frequent and a serious injury in the chest trauma patients in emergency department. And it is easy to induce acute respiratory distress syndrome (ARDS) and respiratory failure. Since the development of modern technology and transportation, flail chest with pulmonary contusion happens more frequently than the past. And its complications and mortality are higher. In order to understand it better and improve the effect of the therapy on flail chest with pulmonary contusion, we reviewed the relative literatures. In this article, the main contents are as followed:① The pathophysiological changes of pulmonary contusion; ② The pathophysiological changes of flail chest with pulmonary contusion; ③ Clinical manifestation of flail chest with pulmonary contusion; ④ Imaging change of flail chest with pulmonary contusion; ⑤ progress in diagnosis and treatment.
The high incidence of hydatid disease in seven northwestern provinces, is one of the reason of "Poverty due to illness, and return poverty due to illness" in China. The incidence of chest hydatid disease in China after hepatic hydatid disease ranks second. Department of thoracic surgery in the First Affiliated Hospital of Xinjiang Medical University is on the domestic leading position of the treatment of chest hydatid disease. Since 1956 the first case of pulmonary hydatid cyst were completed, we have successfully finished the surgical treatment of pediatric chest hydatid disease, chest hydatid disease complex, huge pulmonary hydatid cyst, mediastinal and pleural hydatid cyst, and rib hydatid in our department. To further standardize the treatment of chest hydatid disease, a special formulation of "technical specification for chest hydatid disease diagnosis expert consensus" by our department were produced, in order to help clinicians treat chest hydatid disease by more suitable strategies. This consensus was released in July 2015, for the original version. The definition, diagnosis, treatment principle, and prevention of chest hydatid disease were elaborated and clinical experiences of 60 years were combined with in this consensus, in order to help the clinicians for diagnosis, treatment, and prevention of hydatid disease.
Severe/massive ischaemic stroke is difficult to treat and has poor prognosis. There are limited studies for specific treatment of these conditions and no consensus on their definitions. This proposal suggests definitions and a flowchart for the diagnosis and treatment of these conditions. We focus on predicting and preventing malignant oedema at an early stage, monitoring the level of consciousness and vital signs, and the prevention and management of complications (eg. pulmonary infections). We particularly provide suggestions for the treatment with intravenous thrombolysis, endovascular treatment, antiplatelet and anticoagulation. More studies are warranted to support individualised management of infarct swelling, intracranial hypertension and early rehabilitation for severe/massive ischaemic stroke.
