ObjectiveTo investigate the status of undernutrition, nutritional risk as well as nutritional support in patients with gastrointestinal tumor. MethodsIn this prospective cohort study, patients with gastrointestinal tumor were recruited from Septemper 2009 to June 2011. Patients were screened by using Nutritional Risk Screening 2002 (NRS2002) at admission. Data of the nutritional risk, application of nutritional support, complications, and tumor staging were collected. ResultsNine hundred and sixty-one patients with gastrointestinal tumor were recruited, the overall prevalence of nutritional risk was 38.9% (374/961) at admission, 49.2% （176/358） in gastric tumor and 32.8% （198/603） in colorectal tumor, respectively. The highest prevalence was found in stage Ⅳ gastric tumor 〔87.3% (48/55)〕 and colorectal tumor 〔58.8% (50/85)〕 while the lowest prevalence was found in stage ⅡA gastric tumor 〔16.1% (5/31)〕 and stageⅠcolorectal tumor 〔9.8% (6/61)〕. 62.3% (152/244) of gastric tumor patients with nutritional risk while 48.6% (144/296) without nutritional risk received nutritional support. 37.7% (92/244) of colorectal tumor patients with nutritional risk while 51.4% (152/296) without nutritional risk received nutritional support. The ratio of parental nutrition and enteral nutrition was 1.251. The rate of complications in the gastrointestinal tumor patients with nutritional risk was higher than that in the patients without nutritional risk 〔32.4% (121/374) versus 20.4% (120/587), P=0.000 0〕. For the gastrointestinal tumor patients with nutritional risk, the complication rate of the patients with nutritional support was significantly lower than that of the patients without nutritional support 〔27.5% (67/244) versus 40.8% (53/130), P=0.008 6〕. For the gas trointestinal tumor patients without nutritional risk, the complication rate of gastric tumor patients with nutritional support was significantly lower than that of the patients without nutritional support (P=0.039 6), while the complication rate was not significantly different in the colorectal tumor patients with nutritional support or not (P=0.464 7). ConclusionsPatient with gastrointestinal tumor has a high nutritional risk which is related to tumor staging. Patients with nutritional risk have more complications, and nutritional support is beneficial to the patients with nutritional risk by a lower complication rate.
Objective To investigate the early diagnosis and treatment methods of primary duodenal papilla carcinoma. Methods The medical records of 54 patients with primary duodenal papilla adenocarcinoma underwent operation between January 2002 and December 2008 were reviewed. Results Thirty seven cases received fiberduodenoscopy and 35 cases received ERCP, and the accuracy of them were both 100%. Forty four patients received duodenopancreatectomy and 10 patients received jaundice-reducing operation. The 1-, 3-, and 5-year cumulation survival rate was 68%, 50%, and 29%, respectively. Conclusions Fiberduodenoscopy and ERCP are the effective diagnostic methods for duodenal papilla carcinoma. Early diagnosis and early rational radical operation are essential for successful treatment of duodenal papilla carcinoma.
Objective To evaluate the efficiency and safety of combinative use of radiofrequency and transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Methods Three hundred and twenty-one cases of varicose veins of lower extremity were randomly divided into three groups: group A (102 cases)： endovenouser whole range closure in situ for great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; group B (97 cases)： endovenouser whole range closure in situ for upper leg part of great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; 122 conventional treatment cases, which high ligation and stripping of great saphenous vein, blood vessel branches and communicating branches resection and ligation were used, were selected as controlled group (group C). Consequences and complications of operation were checked. Results In all cases, the symptoms of swelling in lower extremity, soreness and infirmity disappeared within one month after operation, skin pigmentation was alleviated within one month after operation, and disappeared gradually within three months. Contrasting three groups in complications of skin numbness of legs, ecchymosis of upper leg, wound hematoma, and swelling below ankle, there was no statistical difference between group A and B, and there was statistical difference between group A and C, and B and C. There were more complications in conventional group than those in mini-invasive groups. There was no statistical difference in leg ecchymosisa between group B and C. No deep vein thrombosis of lower extremity and incision infection was detected in all cases. Conclusion It is simple and definitely efficient to combine radiofrequency with transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Powered phlebectomy is efficient in removal of varicose vein, but not suitable for phlebectomy for trunk of great saphenous vein.
【Abstract】Objective To study the clinical application of laparoscopic operation. Methods The clinical findings from 13 840 cases of laparoscopic surgery in this hospital from 1992 to 2005 were reviewed retrospectively.Results Laparoscopic operation were performed successfully in 13 653（98.6%）,187 cases were transferred to open operation. Complications were occurred in 115 cases, including common bile duct injury in 3 cases. Combined treatment with laparoscope and endoscope were performed in 162 cases. Eleven thousand three hundred and fiftytwo patients had been succeeded in followup survey. Over 90.0 percent of patients recovered smoothly. Conclusion Laparoscopic operation may be applied in a more extensive scope. The major complications can be reduced by strict procedures of laparoscopic operation. The combined treatment of laparoscope and endoscope should be further studied and widely used.
Objective To evaluate the clinical features and complications of bedside tracheal intubation in intensive care unit ( ICU) , and explore the suitable strategy of intubation. Methods In this retrospective study,42 patients who underwent bedside tracheal intubation in ICU during September 2008 and March 2009 were divided into a schedule group ( n =24) and an emergency group ( n =18) . The time to successful intubation, number of intubation attempts, and complications were recorded. The schedule group was defined as those with indications for intubation and fully prepared, while the emergency group was defined as those undergoing emergency intubations without full preparation due to rapid progression of disease and accidental extubation. Results The success rate for all patients was only 57. 1% on the first attempt ofintubation. The main complications during and after induction were hypotension ( 45. 2% ) and hypoxemia ( 50. 0% ) . Compared with the emergency group, the schedule group had fewer attempts to successful intubation ( 1. 71 ±1. 12 vs. 2. 67 ±1. 75) , higher success rate on the second attempt ( 87. 5% vs.61. 1%) , and lower ypoxemia incidence ( 29. 1% vs. 77. 8%, P lt; 0. 05) . Conclusions The tracheal intubation in ICU is a difficult and high risk procedure with obvious complications. Early recognition ofpatients with indications and well preparation are critical to successful bedside intubation.
Objective To evaluate the complication rate of CT-guided percutaneous lung biopsy and determine the risk factors. Methods A retrospective investigation of patients with CT-guided percutaneous lung biopsy in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine between2002 and 2009 was performed. The risk factors for complications were determined by multivariate analysis of variables related to patients’demographics, lung lesions, biopsy procedures, and individual radiological features. Results 281 biopsy procedures were enrolled. The total complication rate was 55. 9% with pneumothorax 32. 4% ( 91/281) , hemoptysis 34. 5% ( 97 /281) , and cutaneous emphysema2. 1% ( 6 /281) , and with no mortality.The pneumothorax rate was correlated with lesion location, lesion depth, and number of pleural passes. The bleeding risk was correlated with lesion size, lesion depth, and age. Prediction models for pneumothorax and bleeding were deduced by logistic regression. The pneumothorax model had a sensitivity of 80. 0% and a specificity of 62. 4% . And the bleeding model had a sensitivity of 67. 4% and a specificity of 88. 8% .Conclusions Lesion location, lesion depth, and number of pleural passes were independent risk factors for pneumothorax. Lesion size, lesion depth, and age were independent risk factors for bleeding. The prediction models for pneumothorax and bleeding will helpfully reduce the complication of CT-guided lung biopsy.
Objective To evaluate the diagnostic value and safety of surgical lung biopsies ( SLB)in patients with interstitial lung disease ( ILD) . Methods A retrospective analysis was performed on patients undergoing SLB, who were obtained from Chinese literatures through searching PubMed, CBM,Wanfang database, VIP information and CHKD from 2000 to 2010. The data from Affiliated Drum Tower Hospital, Nanjing University Medical College from2000 to 2010 was also reviewed. Results A total of 398cases underwent SLB, including open lung biopsy ( OLB) in 221 cases and video-assisted thoracoscopic lung biopsy ( VATLB) in 177 cases. SLB yielded a specific diagnosis for 386 cases. The total postoperative complication rate was 12. 1% and mortality rate was 2. 0% . The diagnostic yield, post-operative complication rate, and mortality rate between VATLB and OLB had no significant difference. Conclusion SLB is a useful and relatively safe procedure for diagnosis of ILD.
Abstract： Objective To summarize the clinical experiences of performing extracorporeal membrane oxygenation (ECMO) on patients with heart and respiratory failure, and compare the clinical outcomes of Medtronic system and Quadrox PLS system. Methods We retrospectively analyzed the clinical data of 121 heart and respiratory failure patients who underwent ECMO treatment in Fu Wai Hospital from December 2004 to December 2009. Based on the different systems used, 121 patients were divided into two groups. In group M, there were 65 patients including 41 males and 24 females, with an age of 26.6±25.9 years; and they accepted Medtronic ECMO system treatment. In group Q, there were 56 patients including 39 males and 17 females, with an age of 32.4±23.9 years and they underwent Quadrox PLS ECMO system treatment. The evaluation of the clinical outcomes of these two different systems was based on the comparison of transmembrane pressure drop (TMPD), anticoagulation, hemolysis, plasma leakage, organ function, complication and hospital mortality between the two groups. Results Compared with group M, ECMO with Quadrox PLS system was associated with lower TMPD (at the beginning of ECMO: 15.0±6.0 mm Hg vs.28.0±5.0 mm Hg, P=0.000; 24 hours later: 16.0±5.0 mm Hg vs. 30.0±7.0 mm Hg, P=0.000) and less thrombus formation(7.1% vs.23.1%, P=0.037), less plasma leakage (0.0% vs. 50.8%, P=0.000), less hemolysis (14.3% vs. 29.2%, P=0.047). There were no significant differences between the two groups in support duration, complication rate, and hospital mortality(Pgt;0.05). Conclusion Both devices have similar effects for safe clinical application, but Quadrox PLS ECMO system has a relatively high biocompatibility with lower TMPD, less plasma leakage, and thrombus formation.
Abstract: Objective To evaluate the prediction validation of European system for cardiac operative risk evaluation （EuroSCORE） in prolonged intensive care unit (ICU) stay, mortality, and major postoperative complications for Chinese patients operated for acquired heart valve disease. Methods Between January 2004 and January 2006, 2 218 consecutive patients treated for acquired heart valve diseases were enrolled in Fu Wai Hospital. All these patients accepted valvular surgery. Both logistic model and additive model were applied to EuroSCORE to evaluate its ability in predicting mortality, prolonged ICU stay and major postoperative complications of patients who had undergone heart valve surgery. An receiver operating characteristic curve（ ROC) area was used to test the discrimination of the models. Calibration was assessed by HosmerLemeshow goodnessoffit statistic. Results Discriminating abilities of logistic and additive EuroSCORE algorithm were 0.710 and 0.690 respectively for mortality, 0.670 and 0.660 for prolonged ICU stay, 0.650 and 0.640 for heart failure, 0.720 and 0.710 for respiratory failure, 0.700 and 0.740 for renal failure, and 0.540 and 0.550 for reexploration for bleeding. There was significant difference between logistic and additive algorithm in predicting renal failure and heart failure (Plt;0.05). Calibration of logistic and additive algorithm in predicting mortality, prolonged ICU stay and major postoperative complications were not satisfactory. However, logistic algorithm could be used to predict postoperative respiratory failure (P=0.120). Conclusion EuroSCORE is not an accurate predictor in predicting mortality, prolonged ICU stay and major postoperative complications, but the logistic model can be used to predict postoperative respiratory failure in Chinese patients operated for acquired heart valve diseases.
Objective To investigate the security and efficiency of endovascular repair for Stanford type B aortic dissection (AD) with severe complications. Methods Between January 2003 and December 2009, 60 patients having Stanford type B AD with severe compl ications were treated, including 39 males and 21 females with an average age of 43.7 years (range, 34-71 years). Severe compl ications included 27 cases of huge hemothorax, 1 case of paraplegia, 7 cases of acute renal failure,10 cases of cel iac trunk ischemia, 10 cases of superior mesenteric artery ischemia, and 5 cases of severe limb schemia. Emergency stent-graft deployment were appl ied in all patients, and 64 stent-grafts were successfully implanted. Results All patients survived and were followed up 3-86 months. Hemothorax disappeared after 28 days to 3 months of operation in all hemothorax patients; renal function returned normal after 1 to 9 days; l imb and visceral ischemia disappeared gradually after 1 to 14 days; and muscular strength of lower limb in the paraplegia patient began to recover after 4 hours of operation. The postoperative CT angiography showed enlarged true lumen and thrombosis in the false lumen. Conclusion Emergency endovascular repair is a safe and effective method to treat Stanford type B AD with severe complications.
