ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure （internal drainage or external drainage）. MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.
Abstract:Five eyes of acute retinal necrosis(ARN)with multiple retinal breaks and retinal detachment were treated by closed vetrectomy combined with encircling buckle,gas/fluid exchange,nolaser and cryotherapy.After operation,the detached retinas reattached in 4eyes,and among them th visual acuity was 0.2 in 1 eye,and better than 0.05 in 3 eyes.The follow-up duration in 5 eyes was from 6 to18 months and recurrent retinal detachment was found in one eys. （Chin J Ocul Fundus Dis,1996,12: 20-21)
Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.
Objective To summarize the clinical experience of cardiac valve surgery with minimally invasive procedure. Methods Cardiac valve surgery with less invasive techniques were performed in 134 cases. Five aortic valve operations and 2 mitral valve operations were performed through para-sternotomy. Forty-six mitral valve operations and 15 tricuspid valve operations were performed through right anterolateral thoracotomy. Eleven aortic valve operations were performed through limited reversed Z sternotomy. Fifty-five mitral valve operations were performed through limited lower sternotomy. Results Three cases died postoperatively, the mortality was 2.2%, 2 patients died of low cardiac output syndrome, and one died of acute hepatic and renal failure. One hundred and fourteen patients were followed-up from 2 months to 7 years. The follow-up results were excellently. The scar of minimally invasive valve surgery was limited. Conclusion Minimally invasive valve surgery can accelerate recovery, while maintaining overall surgical efficacy. The advantages include a better cosmetic scar, less surgical trauma, minimal respiratory discomfort and a potentially lower risk of infection. It is extremely effective and has become our current technique of choice in every mitral and aortic valve patient.
Objective To summarize the surgical experiences of ventricular septal rupture (VSR) after acute myocardial infarction (AMI) and investigate the time and methods of surgery. Methods From January 1999 to December 2008, 22 patients with VSR after AMI underwent surgical procedures. There were 17 male and 5 female with a age of 3978 years (mean age of 61.77 years). There were 18 cases with anterior VSR and 4 cases with posterior VSR, all of them combined with left ventricular aneurysm. Twentytwo cases underwent ventricular septal repair and aneurysm resection, 16 cases underwent coronary artery bypass grafting concomitantly with a graft of 2.11±1.57. Results There were 2 perioperative deaths (9.09%), 1 died of severe low cardiac output syndrome and 1 died of massive cerebral embolism. The other 20 cases were all cured and discharged. According to cardiac function classification from New York Heart Association（NYHA）, there were 4 cases in grade Ⅲ, 12 cases in grade Ⅱ and 4 cases in grade Ⅰ. Echocardiography showed that there were no VSR shunt and 2 cases with mild mitral valve regurgitation. Postoperative left ventricular enddiastolic diameter (LVEDD) reduced significantly compared with that before operation (50.27±5.33 mm vs. 57.94±6.79 mm, t=4.437, P=0.000). Sixteen cases were followed up, and the follow-up time was 3.24 months (13.9±6.5 months). Four cases were lost. There was no late death and cardiovascular event during following up. There were 11 cases in cardiac function classification (NYHA) grade Ⅱ and 5 in grade Ⅰ. Echocardiography showed that LVEDD reduced significantly (49.50±4.66 mm vs. 57.94±6.79 mm, t=5.041, P=0.000) and left ventricular ejection fraction (LVEF) increased significantly (55.08%±6.72% vs. 45.57%±11.31%, t=2.719, P=0.013)compared with those before operation. Conclusion VSR after AMI is one of the serious complications of AMI. Proper operation timing, perfect preoperative preparation, appropriate perioperative treatment, right surgical method and the avoidance of complications can effectively reduce the mortality and improve the prognosis.
Objectives To evaluate the effect of preoperative body mass index (BMI) on the perioperative and long-term results in esophageal squamous cell cancer patients. Method We retrospectively analyzed the clinical data of 503 patients with esophageal cancer between January 2001 and December 2009. There were 268 males and 235 females with the median age of 57 years ranging from 32-88 years. The associations between preoperative BMI and clinic patholo-gical characteristics were assessed by using the χ2 or Fisher's exact test. Survival analysis was performed by Kaplan-Meier curves with log-rank tests. ResultsThe 1-year, 3-year, 5-year, and 10-year overall survival rate for the entire cohort of patients was 64.0%, 49.0%, 43.0%, and 41.0% respectively. The occurance rates of weight loss, lymph node metastases, and poorly differentiated tumorigenesis represented statistically higher in patients with BMI≤18.5 kg/m2 than those in the patients with BMI>18.5 kg/m2 (P=0.026, P=0.006, P=0.048). For the cohort, the Kaplan-Meier survival analysis showed a significant trend toward a decreased survival in esophageal cancer patients with underweight (P=0.001). No statistical difference in overall complication, anastomotic leakage, and pulmonary complication rate was detected among the different BMI classes(P=0.162, P=0.590, P=0.376). Univariate and multivariate analysis showed that the drinking status, pathological stage, and underweight were the independent prognostic factors. ConclusionsAfter esophagectomy, BMI is not associated with the incidence of postoperative complications in patients. Patients with underweight are usually diagnosed with advanced stage, therefore tend to have poorer survivals than those with normal or over-weight.
Abstract: Objective To determine the incidence, course, potential risk factors and outcomes of postoperative noninfectious fever in aortic surgical patients. Methods We reviewed 549 patients who received operation for aortic aneurysm or dissection in Beijing FuWai Cardiovascular Disease Hospital from January 2006 to January 2008. After excluding patients with a known source of infection during hospitalization, patients who had preoperative oral temperature greater than or equal to 38.0℃, patients who underwent emergency surgery, patients who died of other reasons other than feverrelated factors, and patients with incomplete data, we finally enrolled a total of 463 patients for final analysis. Depending on whether the patients developed a noninfectious fever after operation, we classified them into the febrile group (n=345, highest oral temperature ranging from 38.0-39.3℃) and the afebrile group (n=118, without postoperative fever). Univariate analysis was performed between these two groups of patients, with respect to demographics, operative data and postoperative conditions. Risk factors for postoperative fever were considered for the multivariate logistic regression model if they had a P value≤0.001 in the univariate analysis. Results After operation, 74.5%(345/463) of the patients had noninfectious fever. The minimum temperature of febrile patients on the operation day and the first postoperative day were both higher than afebrile patients（P=0.000，0.000）. The maximum temperature of febrile patients on the operation day, the first, second，third and fourth postoperative days were also higher than afebrile patients（P=0.000，0.000, 0.047, 0.018）. Univariate analysis demonstrated that weight (P=0.000), surgical type (P=0.000), minimum intraoperative bladder temperature (P=0.000), temperature upon ICU admission (P=0.000) and blood transfusion (P=0.000) were all risk factors for noninfectious postoperative fever. The multivariate logistic regression showed that surgical sites of thoracic and thoracoabdominal aorta (odds ratio: 4861; 95% confidence interval: 3.029，5.801; P=0.004), lower minimum intraoperative bladder temperature (odds ratio: 1.117; 95% confidence interval:1.013，1.244;P=0.040) and higher temperature on admission to the ICU (odds ratio: 2.570; 95% confidence interval:1.280，5.182;P=0.008) were significant predictors for postoperative noninfectious fever. Conclusion Noninfectious postoperative fever following aortic surgery is very common. Predictors of noninfectious postoperative fever following aortic surgery include surgical sites (thoracic or thoracoabdominal aorta), low intraoperative core temperature and temperature elevation in the immediate postoperative period.
Primary bronchopulmonary carcinoma occurs in the bronchial mucosa epithelium, also called lung cancer (LC), and has currently become the first cause of death of malignant tumors in China. With constant efforts of Chinese physicians, the diagnosis and management of LC has made certain progress, but standardized surgery for LC still varies to a great extent due to difference regions, nature of medical centers, and technical levels. Complete and standardized surgical resection can provide good long-term survival for patients with stageⅠ, Ⅱand partly ⅢA LC, and cannot be a substitute for other treatment, which shows the importance of standardized surgery. As the most solid member, surgery plays a decisive role in comprehensive multidisciplinary treatment of LC. Today's medical development requires thoracic surgeons to provide most standardized and individualized treatment with principles of evidence-based medicine. This review focuses on progress of standardized surgery for stage Ⅰto ⅢA LC.
Objective To summarize our experience of using rigid bronchoscopy in the managent of patients with tracheobronchial disease. Methods From Sep.2002 to Nov.2007, 44 patients of tracheobronchial disease（31 men，13 women, median age 51.9 years) underwent rigid bronchoscopic operations. All procedures were carried out under general anesthesia with high frequency jet ventilation. After the rigid bronchoscope was placed in the main trachea through the mouth , the airway was checked out firstly, and then the lesion was removed by repeated freezing, argon plasma coagulation, cauterization or mechanical ablation, and a stent maybe implanted while needed. Results All 54 procedures were accomplished endoscopically without mortality or major morbidity (16 clearence,19 core out,8 scar clearance,3 foreign body removal, 8 stent insert or removal).The lesion located at trachea in 19 cases, at carina in 4 cases,at left main bronchus in 11 cases and at right main bronchus in 10 cases. There were 17 benign diseases and 27 malignant diseases. There were 3 slight complications. 16 patients compliating with benign disease were followed-up and 1 patient was missed,there was no tumor recurrence except 3 patients complicating with tracheal scar who received reoperations during 4-44 (mean 23.0) months follow-up period. Of the 27 malignant cases,23 patients were followed-up and 4 patients were missed, the follow-up period were 5-58(mean 27.1)months.3 patients died in one months after operation of other disease; the other patients all survived more than one month,especially 7 patients who received radical resection of the tumor survived more than one year. Conclusions These data show that rigid bronchoscope can be applied safely and effectively in the management of tracheobronchial disease.
OBJECTIVE:To evaluate the effect and causes of failure of vitreoretinal(VR)surgery in rhegmatogenous retinal detachments associated with choroidal detachment. METHOD:Reviewing the operative effects of the vitreoretinal surgeries in 61patients(61 eyes)with rhegmatogenous retinal detachment associated with choroidal detachment and PVR in this hospital.Vitrectomy,peeling of preretinal membranes,fluid/air echange and inert gas,silicone oil tamponade were used in thesepatients according to need. RESULTS:On discharge from the hospital,the postoperative effect obtained in 40 case(65.57%),and out of 35 eyes receiving the inert gas tamponade 26(74.3%) got effective pesults.Fourteen cases were followed up for 3 months(averge 9.5 months)and 10(7.4%）of themrevealed stable.The factors of influencing VRsurgery seemed to be the range of choroidal detachments,numbers of opreative times,the inert gas tamponede and the time of corticosteroid application.The causes of failure of opreation might relate to severe and antrior PVR,and giant tears. CONCLUSIONS:The VR surgery was thought to be profitable in treating rhegmatogenous retinal detachment associated with choroidal detachment and PVR. （Chin J Ocul Fundus Dis,1996,12: 16-19)
