Objective To explore the perioperative management of the coexisting diseases for the elderly patients with gastric cancer. Methods The clinical data of perioperative management for coexisting diseases in 528 patients with gastric cancer over 70 years old treated in the First Affiliated Hospital of China Medical University from March 1980 to November 2008 were analyzed retrospectively. Results The main coexisting diseases included cardiovascuclar disease (259 cases, 49.05%), respiratory disease (161 cases, 30.49%), diabetes (72 cases, 13.64%). Adjusting blood pressure and blood glucose, improving cardiopulmonary function, and hepatic and renal function were mainly given. The common postoperative complications included intestinal obstruction (10 cases), pneumonia (10 cases), reflux esophagitis (9 cases), functional evacuation disorder of gastric remnant (7 cases), and anastomotic leakage (5 cases). Ten patients died during perioperative period: 6 died of heart and lung failure, 2 of acute myocardial infarction, 1 of anastomotic leakage, 1 of intestinal obstruction. Conclusions The common coexisting diseases in the elderly patients with gastric cancer are hypertension， bronchitis and diabetes. Complete assessment of the patient’s general health before operation and intensive perioperative management of the coexisting diseases not only can decrease the risk of surgical procedures， but also decrease the incidence of complication and perioperative mortality.

Abstract： Objective To explore the impact of obesity on postoperative morbidity and mortality after pneumonectomy. Methods Clinical data of 3 494 patients with pulmonary diseases who underwent pneumonectomy in Shanghai Pulmonary Hospital from September 2003 to December 2007 were retrospectively analyzed. All the 3 494 patients were divided into two groups according to the patients’ preoperative body mass index （BMI）. There were 3 340 patients in the non-obesity group （BMI＜28 kg/m2） including 2 502 males and 838 females with their average age of 61.9±10.7 years， and 154 patients in the obesity group （BMI≥28 kg/m2） including 87 males and 67 females with their average age of 59.7±9.6 years. Univariate analysis and logistic regression were used to analyze the impact of obesity （BMI≥28 kg/m2） on postoperative morbidity after pneumonectomy. Results There were a total of 26 cases of perioperative death， including 23 patients in the non-obesity group and 3 patients in the obesity group. There was no statistical difference in mortality between the two groups ［0.7% （23/3 340） vs. 1.9% （3/154）， P=0.118］. There was no statistical difference in any particular postoperative morbidity or incidence of pulmonary complications between the two groups （P＞0.05）. Other than pulmonary complications， the incidence of postoperative complication in other body systems of the obesity group was significant higher than that of the non-obesity group （P＜0.05）. The incidence of cerebrovascular accidents， myocardial infarction and acute renal failure of the obesity group was significant higher than those of the non-obesity group （P＜0.05）. Logistic regression showed that obesity （BMI≥28 kg/m2） was not an independent risk factor for postoperative morbidity after pneumonectomy ［B=0.648， OR=1.911， 95% CI（0.711， 5.138），P=0.199］. Conclusion Obesity is not a significant risk factor of postoperative mortality or morbidity after pneumonectomy.
Objective To compare surgical outcomes of Stanford type A acute aortic dissection between operations at midnight and daytime. Methods From January 2004 to March 2013，195 patients with Stanford type A acute aortic dissection received surgical treatment in Nanjing Hospital Affiliated to Nanjing Medical University （Nanjing Cardiovascular Disease Hospital）. Patients with identical or similar propensity scores were matched from 127 patients who underwent emergency operation at daytime and 68 patients who underwent emergency operation at midnight. A total of 58 pairs of matched patients which had the same or similar propensity score were selected in daytime surgery group （n=58，43 males and 15 females，47.7±14.6 years） and midnight surgery group （n=58，45 males and 13 females，48.3±14.6 years）. Operation time，postoperative chest drainage，mechanical ventilation time，postoperative incidence of dialysis and tracheostomy，length of ICU stay and in-hospital mortality were compared between the daytime group and midnight group. Results A total of 58 pair of patients were matched in this study. There was no statistical difference in postoperative incidence of tracheostomy ［19.0% （11/58） vs. 6.9% （4/58），P=0.053］ or in-hospital mortality ［8.6% （5/58） vs. 6.9%（4/58），P=0.729］ between the midnight group and daytime group. Operation time （485.7±93.5 minutes vs. 428.5±123.3 minutes，P=0.048），postoperative chest drainage （979.5±235.7 ml vs. 756.6±185.9 ml，P=0.031），mechanical ventilation time （67.9±13.8 hours vs. 55.7±11.9 hours，P=0.025），postoperative incidence of dialysis ［17.2% （10/58） vs. 5.2%（3/58），P=0.039］ and length of ICU stay （89.4±16.2 hours vs. 74.8±12.5 hours，P=0.023） of the midnight group weresignificantly longer or higher than those of the daytime group. A total of 107 patients were followed up for 4-6 months after discharge. During follow-up，there was no late death. Among the 13 patients who required postoperative dialysis，12 patientsno longer needed regular dialysis. Conclusion Emergency operation at midnight does not increase in-hospital mortalitybut increase some postoperative morbidity in patients with Stanford type A acute aortic dissection. Whether at midnight or daytime，better preoperative preparation and surgeons’ vigor are needed for timely surgical treatment for patients with Stanford type A acute aortic dissection.
Objective To investigate clinical outcomes and perioperative management of off-pump coronary artery bypass grafting （OPCAB） for patients following acute myocardial infarction （AMI）.?Methods?From January 2006 to March 2010， 239 consecutive patients underwent OPCAB on the 14-27 （20.55±3.91） d following AMI（AMI group）in Renji Hospital，School of Medicine of Shanghai Jiaotong University. Preoperative MB isoenzyme of creatine kinase（CK-MB） level was （15.82±6.24） U/L and cardiac troponin I（cTnI） was （0.07±0.04） ng/ml. Clinical data of 406 patients without myocardial infarction history who underwent OPCAB during the same period were also collected as the control group for comparison.?Results?The 30-day mortality of AMI group was 2.51% （6/239）. The causes of death were circulatory failure in 4 patients， ischemic necrosis of lower extremity caused by intra-aortic balloon pump （IABP） in 1 patient and pneumonia with septic shock in 1 patient. Dopamine usage in AMI group was significantly higher than that of the control group （61.51% vs. 37.44%， P=0.001）. Intraoperative or postoperative IABP implantation was more common in AMI group， but there was no statistical difference between the two groups（P＞0.05） . Postoperative drainage and blood transfusion in AMI group were significantly larger than those of the control group （385.18±93.22 ml vs. 316.41±70.05 ml， P=0.022；373.68±69.54 ml vs. 289.78±43.33 ml， P=0.005， respectively）. But there was no statistical difference in re-exploration rate between the two groups （P＞0.05）. There was no statistical difference in the incidence of postoperative new onset atrial fibrillation between the two groups （P＞0.05）. Incidence of acute kidneyinjury of AMI group was significantly higher than that of the control group （13.81% vs. 8.62%， P=0.038）. Postoperative 30-day mortality of AMI group was higher than that of the control group， but there was no statistical difference between the two groups （2.51% vs. 1.48%，P＞0.05）. There was no statistical difference in ICU stay time and postoperative hospital stay between the two groups （2.01±0.95 d vs. 1.78±0.98 d；10.33±4.16 d vs. 9.89±4.52 d， respectively， P＞0.05）. A total of 211 patients （88.28%）in AMI group were followed up for 2.89±1.02 years， and 28 patients （11.72%） were lost during follow-up. Twenty-five patients died during follow-up including 14 cardiac deaths. One-year survival rate was 97.63%， and five-year survival rate was 88.15%.?Conclusion?It’s comparatively safe to perform OPCAB for patients at 2-4 weeks following AMI when their CK-MB and cTnI levels have returned to normal range.
Abstract： Objective To analyze risk factors for perioperative mortality in the arterial switch operation (ASO), in order to provide better operation and decrease the mortality rate. Methods We enrolled 208 ASO patients including 157 males and 51 females at Fu Wai Hospital between January 1, 2001 and December 31, 2007. The age ranged from 6 h to 17 years with the median age of 90 d and the weight ranged from 3 kg to 43 kg with the median weight of 5 kg. Among the patients, 127 had transposition of great artery (TGA) with ventricular septal defect (VSD), and 81 patients had TGA with intact ventricular septum (IVS) or with the diameter of VSD smaller than 5 mm. Coronary anatomy was normal (1LCX2R) in 151 patients and abnormal in the rest including 15 patients with single coronary artery, 6 with intramural and 36 with inverse coronary artery. Preoperative, perioperative and postoperative clinical data of all patients were collected to establish a database which was then analyzed by univariate analysis and multivariate logistic regression analysis to find out the risk factors formortality in ASO. Results There were 24 perioperative deaths (11.54%) in which 12 died of postoperative infection with multiple organ failure (MOF), 10 died of low cardiac output syndrome, 1 died of pulmonary hypertension, and 1 died of cerebral complications. Among them, 20 patients (18.30%) died in early years from 2001 to 2005, while only 4 (4.00%) died in the time period from 2006 to 2007, which was a significant decrease compared with the former period (Plt;0.05). The univariate analysis revealed that cardiopulmonary bypass (CPB) time was significantly longer in the death group than in the survival group（236±93 min vs. 198±50 min, P=0.002）, and occurrence of major coronary events (33.3% vs. 2.2%, P=0.000) and unusual coronary artery patterns（33.3% vs. 6.5%,P=0.000） were much more in the death group than in the survival group. Multivariate logistic regression analysis showed that early year of [CM(159mm]operation (OR=7.463, P=0.003), unusual coronary artery patterns (OR=6.303,P=0.005) and occurrence of majorcoronary events (OR=17.312, P=0.000) were independent predictors for perioperative mortality. Conclusion The ASO can be performed with low perioperative mortality in our hospital currently. Occurrence of major coronary events, unusual coronary artery patterns and year of surgery before 2006 are independent predictors for perioperative mortality.
Abstract: Objective To summarize the experience of combined coronary artery bypass grafting(CABG) and valve replacement. Methods From May 1997 to March 2006, the results of 80 consecutive patients undergone valve replacement (MVR) and CABG were analyzed. CABG were performed withtotal grafts in 159 grafts (mean 1.99 grafts), with mitral valve replacement (MVR) in 49 patients, with aortic valve replacement (AVR) in 18 patients, with MVR+AVR in 13 patients(mechanical valve replacement in 68 and biological valve replacement in 12). Results The hospital time after operation was 19.2±13.4d. The hospital mortality rate was 12.5% (10/80). The primary cause of death included low cardiac output yndrome, acute renal failure, nervous system complications ,ventricular fibrillation and cardiac arrest. Multivariate testing of preoperative and operative description identified that preoperative myocardial infarction, worse cardiac function, radiographic cardiac enlargement and low ejection fraction were associated with an increase of hospital mortality (P＜0.05). There were postoperative complications including bleeding, severe ventricular arrhythmia, nervous system complications and incision infection. Followup of 58 patients (82.86%, range 6 to 60 months) showed the symptoms of angina pectoris and heart failure were significantly relieved. There were 2 longterm deaths (cerebral infarction and lung infection). Conclusion Combined CABG and valve replacement is an effective way for treatment of coronary artery and valvular heart disease. Improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for success operation.
Objective To analyze the outcome of arterial switch operation （ASO） for surgical repair of complete transposition of the great arteries （TGA）, and to investigate the risk factors influencing the mortality of ASO. Methods The clinical data of patients suffered from TGA and treated with ASO from the January 2003 to December 2004, and the clinical records in hospital including eehoeardiogram and operation record were collected. The clinical data were analyzed by chi-squared test and logistic muhivariable regression analysis, including the age undergone operation, body weight, diagnosis, anatomic type of coronary artery, cardiopulmonary bypass time, aortic crossclamping time, circulation arrest time, assisted respiration time after operation, the delayed closure of sternum and so on. The risk factors influencing the early mortality of the ASO were analyzed. Results Sixty seven patients were operated with ASO, five patients died during the peri-operative period. The outcome of univariate analysis indicated that risk factors influencing the mortality of ASO included： age（P=0. 004）, body weight （P=0. 042）, anatomic type of coronary artery （P= 0. 006） and extracorporeal circulation time （P= 0. 048）, the length of the CICU stay（P= 0. 004） and the hospital stay（P=0. 007） after operation in the TGA/VSD patients were longer than those in TGA/ IVS patients. The logistic muhivariable regression analysis indicated that the age at operation （P= 0. 012）, coronary arteries anomaly （P = 0.001 ）and the longer cardiopulmonary bypass time （P = 0. 002） were correlated with the increase of death rate. Conclusion It could be good results for TGA patients who was repaired with ASO. The age at operation, the coronary arteries anomaly and the longer cardiopulmonary bypass time are the risk factors influencing the mortality.
