Objective To explore the diagnostic methods, therapy and the prognostic factors for the ruptured abdominal aortic aneurysm (RAAA). Methods The clinical data of 23 patients (males 15, females 8, age range 35-78, mean age 65) with RAAA below the level of renal arteries, who were treated with surgery, were collected from April 1999 to December 2005 and were analyzed retrospectively. Seven cases had a history of RAAA, 6 cases had pulsating abdominal masses; 15 cases were diagnosed by emergency Doppler ultrasonic examination or CT. All of the patients underwent emergency surgical operation: The ruptures of the abdominal aorta below the level of renal arteries were obstructed by using clamp ring or using transluminal ballon according to conditions of each patient. The aritficial vascular graft was then taken after the control of hemorrhage. Results There were 9 (39%) patients died within 30 d after the emergency operation. The causes of death included acute renal failure because of hemorrhagic shock (4 cases), multiple organ failure (3 cases), and respiratory-circulatory failure (2 cases).Conclusion Surgery may be an effective treatment for RAAA. The critical step of the operation was to control hemorrhage by obstructing the proximal end of the aortic rupture according to the conditions of each patient. The main postoperative complications and causes of death include acute cardiovascular and cerebrovascular diseases, renal failure and pneumonia.
ObjectiveTo investigate the clinicopathologic and epidemiological characteristics of patients with gastric cancer at our hospital in the past six years． Methods A total of 958 patients with gastric cancer were selected from January 2004 to December 2009 and clinicopathologic characteristics such as basic data, pathological type, tumor location, and TNM stage were retrospectively analyzed. ResultsOf the 958 patients，697 cases (72.8%) were male and 261 cases (27.2%) were female, and the age ranged from 26 to 91 years old (mean 62.6 years old). The occurrence rate of gastric cancer was higher in the patients of 46-65 years old (49.4%, 473/958) than that in the patients of ≥66 years old (42.3%, 405/958) and ≤45 years old (8.3%, 80/958). Regarding pathologic type, the majority of advanced gastric cancers (70.1%) were Borrmann Ⅱ, the adenocarcinoma and signetring cell carcinoma accounted for 82.3% and 7.8%, respectively. The cancer of gastric cardia accounted for 53.0%. Stagestratified analysis revealed that the majority of gastric cancers (47.4%) were stage Ⅲ. Conclusion①A prevalence of gastric cancer is found in middle, elderly male patients. Poorly differentiated adenocarcinoma in cardia is prominent. ②Patients with high malignant ganstrie cancer are younger. ③The majority of patients who underwent the surgical treatments have advanced or metastatic tumor, therefore it is necessary to improve the early diagnosis of gastric cancer.
Abstract： Objective To explore the optimal timing and treatment of acquired Lutembacher’s syndrome. Methods Sixteen acquired Lutembacher’s syndrome patients were studied retrospectively based on records collected between January 2000 and December 2009 in Beijing Anzhen Hospital. There were 9 males and 7 females at age of （39.45±10.23）years. All of them underwent endotracheal intubation, intravenous general anesthesia, and cardiopulmonary bypass. All patients were operated on through a median sternotomy incision into the chest, the right atrium, atrial septal defect to expand with mitral valve replacement and atrial septal defect repair. Postoperative mortality and perioperative complications were observed. During follow-up, periprosthetic leakage was observed using echocardiography, along with the level of residual atrial septal shunt, ventricular size, pulmonary artery pressure changes, and improvement in cardiac function. Results Two of the 16 patients（12.5%）died, one of renal failure, and one of respiratory failure. One patient required extracorporeal membrane oxygenation for 3 days, one required continuous renal replacement therapy for 11 days because of acute renal failure, and one experienced respiratory failure and used a respiratory machine for 23 days. All three of those patients recovered. Fourteen patients were followed up for between six months and five years, and the follow-up rate was 100%. The left ventricular end-diastolic diameter was （42.1±5.7） mm, as measured by echocardiography six months post-operation. There was no detectable periprosthetic leakage or residual shunt. The ejection fraction was （67.4%±6.7%）, and estimation of pulmonary artery pressure was （23.4±5.4） mm Hg. Twelve patients were class Ⅱ（ New York Heart Association） and two patients were class Ⅲ. Conclusion Acquired Lutembacher’s syndrome should be treated promptly if patients’ left ventricular end stage diastolic volume index is good enough to ensure they can tolerate surgery. Extracorporeal membrane oxygenation （ECMO）should be used early in patients who are anticipated to be difficult to withdraw from extracorporeal circulation perioperatively.
Objective To evaluate the clinical effectiveness of different surgical treatments for recurrent pterygium. Methods Databases such as The Cochrane Library, PubMed (1966 to 2011), EMbase (1989 to 2011), CNKI (1979 to 2011), VIP (1989 to 2011) and WanFang Data (1982 to 2011) were electronically searched for randomized controlled trials (RCTs) on different surgical treatments for recurrent pterygium, and the relevant references were also retrieved. According to the inclusion criteria, we screened literature, extracted data, and critically assessed the quality of RCTs. Then the meta-analysis was conducted using RevMan 5.0 software. Results A total of 19 RCTs were included. The results of meta-analyses showed, limbal stem cell autograft transplantation (LAT) combined with amniotic membrane transplantation (AMT), LAT alone, and intraoperative using of mitomycin C, effectively reduced the recurrence rate of recurrent pterygium. Statistic differences were found (Plt;0.01) when they were compared with conventional pterygium excision alone or plus AMT. Conclusion Current evidence shows LAT+AMT, LAT alone, and intraoperative using of mitomycin C can effectively reduce the recurrence rate of recurrent pterygium. But this conclusion still needs to be proved by large-scale RCTs due to the limited quantity and quality of the included studies.
Objective To investigate the diagnosis and treatment of congenital choledochal cysts(CCC) in children. MethodsThe manifestation, auxiliary examination, mode of operation and effect of 42 patients with CCC in children from Jan., 1980 to June, 1999 were analyzed retrospectively.Results The patients with the triad of jaundice, an abdominal mass, and pain was 38.1% among the 42 patients. B-ultrasonic diagnosis was made with a correct diagnostic rate of 95.2%. The effective rate of internal drainage was significantly lower than that of resection of the cyst(χ2=19.36, P＜0.001) while the reoperation rate and incidence of carcinoma of internal drainage were higher than those of resection of the cyst(χ2=11.59, P＜0.001 and χ2=4.97, P＜0.05). Conclusion B-ultrasonic diagnosis is recommended as the first examination method. Internal drainage should be abandoned. Resection of the cyst with Roux-Y hepaticojejunostomy is recommended as the treatment of choice on extrahepatic cholangiectasis. Liver transplantation is a reasonable choice to treat the diffuse intrahepatic cholangiectasis.
ObjectiveTo summarize our experience of surgical treatment for right pulmonary artery originated from the ascending aorta by using adult diameter artificial vascular and study the operative indication, design, method, and therapeutic efficacy. MethodsWe retrospectively analyzed clinical data of 11 patients with right pulmonary artery originated from ascending aorta in The Second Affiliated Hospital of Harbin Medical University from May 2008 through December 2013, who were treated by using adult diameter artificial vascular. The patients ranged from 4 months to 25 months old, weighted 4-15 kg. Among of them, 4 patients had persistent truncus arteriosus and 7 had aortopulmonary septal defect. All patients were complicated with moderate pulmonary hypertension. All the patients underwent one stage surgical repair under extracorporeal circulation and cardiac arrest. During the surgery, end to side anastomosis was done between the right pulmonary artery and 16-18 mm diameter artificial blood vessels. And artificial blood vessel was connected to the main pulmonary artery or right ventricle outflow tract incision from the aorta above. ResultsThe average operation time was 179-325 (224±68) min. The average cardiopulmonary bypass (CPB) time was 81-208 (117±54) min. The average aortic clamping time was 29-63(42±21) min. The mean residence time in ICU was 71-197 (109±42) hours. The average assisted mechanical ventilator time was 59-191 (91±26) hours. The average length of stay in hospital was 21-39 (28±11) days. Low cardiac output syndromes caused by pulmonary arterial hypertension occurred in 5 patients including 2 deaths and 3 patients with good recovery by reducing the pulmonary arterial pressure and peritoneal dialysis. The result of postoperative cardiac color ultrasound examination of 9 survival patients showed vascular prosthesis, no distortion, no stenosis of the anastomosis, deformity correction satisfaction. Nine patients were followed up for 3-60 months. The results of echocardiography showed no anastomosis and artificial vascular stenosis, and the pulmonary arterial pressure decreased significantly. ConclusionThe right pulmonary artery originated from the ascending aorta in children should be operated as soon as possible. Compared the adult diameter artificial vascular treatment for one stage repair of right pulmonary artery from the ascending aorta with other operation methods, both short-term and long-term effects are good. Postoperative low cardiac output syndrome is a common complication.
Epilepsy is one of the most common neurological diseases in children, about 2/3 can be seizure-free after anti-seizure medications (ASMs) treatment, but there are still some drug-resistant epilepsy (DRE) need surgical treatment, epilepsy surgery including excision surgery, dissociation surgery and palliative surgery, surgery can make 30%~40% DRE fully controlled. Clinicians usually choose to discontinue ASMs after seizure-free for 1 to 2 years after epilepsy surgery, but there has been controversy about whether to discontinue ASMs after surgery in children with epilepsy, how long to discontinue ASMs, the timing of ASMs withdrawal, and there is still a lack of unified guidelines. This article will comprehensively analyze and summarize the risk of recurrence after ASMs withdrawal in children with epilepsy.
With the progress of genetic testing technology, a large proportion of genes associated with epilepsy are revealed. And these genes are often linked to drug-resistant epilepsy (DRE), for which surgical treatment can be an important intervention. This article reviews the progress of surgical treatment for gene-related epilepsy and focuses on influence factors of surgical outcomes, including timing of surgery, extent of lesion resection, and preoperative assessment methods. Through early surgical intervention, some patients with specific gene mutations (eg. TSC), can significantly improve neural development and control epilepsy greatly while some patients with other gene mutations (eg. SCN1A) have less favorable outcomes. Individualized preoperative assessment, accurate localization of the epileptogenic zone, and complete resection of the lesion are key to good prognosis. Although current studies are mostly based on small sample sizes, the existing evidence provides a theoretical foundation for the advancement of epilepsy surgery toward more precise approaches.
Objective To investigate the clinicopathological characteristics and surgical treatment of intrathoracic Castleman disease(CD). Methods Clinical data of 14 cases athologically diagnosed as CD as analysed retrospectively. There were 6 males and 8 females, with an average age of 29 years(17-58). All were undergone surgical resection or biopsy. Among the 12 patients who had unicentric CD, 11 were performed open thoracotomy and lymphadenectomy with posterolateral or sternum approach, and one was treated by video assisted mini thoracotomy(VAMT). For the diagnosis of multicentric CD, one of the 2 patients had video assisted thoracic surgery(VATS) and wedge resection of the lung, and the other had video mediastinoscopy. Results No patient died perioperatively. All were successfully restored except two complications. One had dyspnea in the second postoperative day, as a result of the softening and collapse of bronchial wall in the entrance of the right main bronchus, which revealed by bedside fiberoptic bronchoscopy.One who had lymphadenopathy in the aortopulmonary window suffered from transient hoarseness after surgery. They recovered after symptomatic treatment finally. Regarding pathological classification, there were 11 cases of hyaline vascular type, 2 cases of plasma cell type and 1 case of mixed cellularity type. 13 cases were followed up for 8-110 months and longterm survive was achieved. No recurrence was observed in the 11 cases with unicentric CD and no relapse was occurred in the 2 cases with multicentric CD. Conclusion Both freezing pathology during operation and paraffin pathology postoperation are important for establishing the diagnosis. For unicentric CD, the clinical symptoms are significantly alleviated and it can be universally cured after operation. Multicentric CD needs multiple therapies after the diagnostic procedure and close follow-up.
ObjectiveTo analyze the clinical characteristics and surgical treatment of bicuspid aortic valve combined with thoracic aortic dilation. MethodsWe retrospectively analyzed the clinical data of 68 patients of bicuspid aortic valve combined with thoracic aortic dilation underwent surgical treatment in our hospital between January 2010 and June 2014. There were 47 males and 21 females at age of 26-77(44.5±16.3) years. Different surgical treatments including Wheat procedure(n=22), aortic valve replacement+ascending aortoplasty(n=10), Bentall procedure(n=13), aortic valve replacement+ascending aortic replacement+right hemi aortic arch replacement(n=13), Bentall procedure+ascending aortic replacement+right hemi aortic arch replacement(n=8), Bentall procedure+ascending aortic replacement+total arch replacement+stented elephant trunk(n=2) were carried out according to the type. ResultsAll 68 patients underwent surgical treatment. The mortality in hospital is at 4.4%(3/68). The postoperative complications were neurological and mental complications(n=3), pneumonia(n=2), and exploratory thoracotomy(n=2). We followed up 63 patients for 6 months to 4 years. A total of 62 patients were well without reoperation except one death at the end of following-up 2 years. ConclusionBicuspid aortic valve combined with thoracic aortic dilation has diversiform clinical characteristics. The surgical treatment should be chosen according to the aortic valve and thoracic aortic lesion characteristics.
