Objective To investigate the joint effects of selective digestive decontamination (SDD) and glutamine (Gln) on preventing intestinal bacterial translocation of orthotopic piggyback liver transplantation and to observe the incidence of postoperative pneumonia in rabbit. Methods Thirty rabbits received orthotopic piggyback liver transplantation and were randomly divided into three groups (SDD group, SDD+Gln group and control group). Mixed emulsion of tobramycin, polymyxin E and nystatin were given to the rabbits in SDD group. Same dosage of the above components plus Gln were given to the rabbits in SDD+Gln group. Samples of portal vein blood, ileum tissue and lung tissue were obtained in each group at different phases during and after operation, the pathological changes of ileum tissue, the bacterial translocation in blood of portal vein and the incidence of postoperative pneumonia were detected. Results The mixing section area of intestinal blood capillaries in SDD+Gln group was smaller compared with control group (P＜0.05， P＜0.01) and SDD group (P＜0.05) while the portal vein was obstructed for 15, 30 and 45 min, and after the operation, respectively. The length of ileum villus in SDD+Gln group was longer than that in control group (P＜0.05) and in SDD group (P＜0.05) before the portal vein was obstructed, but the length of ileum villus in control group gradually became longer and eventually exceeded that in SDD+Gln group at the time of 45 min after the portal vein was obstructed (P＜0.05). After the operation, the length of ileum villus in SDD+Gln group was significantly longer than that in SDD group (P＜0.05) and control group (P＜0.01). At the time of 45 min after the obstruction of portal vein and 30 hours after operation, the positive rate of cultured bacterial in the blood of portal vein in SDD+Gln group was significantly lower than that in control group (P＜0.05, P＜0.01). The incidence of postoperative pneumonia in SDD+Gln group and SDD group were significantly lower than that in control group (P＜0.05,P＜0.01). Conclusion Gln could nourish intestinal epithelium of mucous membrane.When combined with SDD, it could decreased the incidence of intestinal bacterial translocation occurred during the obstruction of portal vein and after operation, so as to decrease the incidence of postoperative pneumonia.

ResultsFor elderly patients with colorectal cancer radical operation, pulmonary infection and wound infection were the common complications.Single factor and logistic regression analysis showed that medical comorbidity, hypoproteinemia, operation time, Dukes staging, and smoking were risk factors of postoperative complications in the colorectal cancer patients. ConclusionFor elderly patients with colorectal cancer underwent radical operation, pulmonary infection and wound infection are the common complications.It's occurrence by various factors.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To explore the factors associated with clinic follow-up of old patients with colorectal cancer and provide more evidence to improve the efficiency and quality of clinic follow-up after sugery. Methods The data of 253 patients who were underwent sugery because of old colorectal cancer in our hospital from January 2009 to May 2010 were reviewed. Data about the rate and times of clinic follow-up within 6 months after operation were collected via Hospital Information Systerm, then the follow-up rate was calculated, and to analyse the possible factors associated with follow-up times and rate. Results The total follow-up rate was 84.2%（213/253）, and the total times of follow-up was between 0 to 24 times per one, （4.08±0.03）times on average. On the times of follow-up, patients inside the city was higher than that outside, patients with medical or postoperative complications were higher than those without, and patients with a stoma was lower than that without, and the differences were statistically significant （P＜0.05）.While on the follow-up rate, patients underwent a radical sugery or with a stoma were lower than those not or without, and the differences were statistically significant （P＜0.05）. Conclusions The clinic follow-up of old colorectal cancer patients is not satisfactory, and the possible factors associated with follow-up times or rate are the distance between residence and hospital, have medical complications or not, have postoperative complications or not, radical sugery or not, and with a stoma or without.
Objective To investigate long-term echocardiography characteristics and their clinical significance of patients after mitral valve replacement （MVR）. Methods We retrospectively analyzed clinical data of 204 patients who underwent prosthetic MVR and finished echocardiography examination at least 5 years after surgery in West China Hospital of Sichuan University. There were 44 male patients and 160 female patients with their age of 23 to 73 （50.9±10.6）years. Postoperatively， all the patients were followed up for 5-15 （7.9±2.3）years and regularly received echocardiography examination at the outpatient department. Analysis variables included left atrium （LA） dimension， left ventricle （LV） dimension，right atrium （RA） dimension， right ventricle （RV） dimension， left ventricular ejection fraction （LVEF） and effective orificearea （EOA） of the mitral valve. Results Long-term echocardiography showed that LA and LV dimensions were signifi-cantly smaller than preoperative dimensions （P＜0.05）， while RA and RV dimensions were not statistically different from preoperative dimensions （P＞0.05）. Long-term LVEF was significantly higher than preoperative value （P＜0.05）. Long-term EOA was 1.1-4.8 （2.3±0.5）cm2， including EOA of 1.1-1.4 cm2 in 7 patients （3.4%，7/204），and 1.6-1.9 cm2in 42 patients （20.6%，42/204）. During long-term follow-up， 7 patients underwent their second heart surgery， including2 patients with prosthetic valve dysfunction， 1 patient with prosthetic perivalvular leak and severe hemolytic anemia，3 patients with severe tricuspid regurgitation which were not improved after medication treatment， and 1 patient with moderateaortic valve stenosis and regurgitation. Two patients had left atrial thrombosis during follow-up， including 1 patient who died of endocarditis 7 years after surgery， and another patient who was still receiving conservative therapy and further follow-up. Conclusion Concomitant tricuspid or aortic valve disease should be actively treated during MVR， and postoperative patients need better follow-up. Many patients after MVR need long-term cardiovascular medication treatment during follow-up in order to improve their heart function and long-term survival rate.
Objective To explore the application of combined optimized machine learning algorithm for predicting the risk model of postoperative infectious complications of gastric cancer and to compare the accuracy with other algorithms, so as to find reliable biomarkers for early diagnosis of postoperative infection of gastric cancer. Methods The clinical data of 420 patients with gastric cancer at the Third Affiliated Hospital of Anhui Medical University from May 2018 to April 2023 were retrospectively analyzed and the patients were randomly divided into training set and validation set. Univariate analysis was used to determine the risk factors of postoperative infectious complications. Six conventional machine learning models are constructed using the training set: linear regression, random forest, SVM, BP, LGBM, XGBoost, and MGA-XGBoost model. The validation set was used to evaluate the seven models through evaluation indicators such as ACC, precision, ROC and AUC. Results Postoperative infectious complications were significantly correlated with age, operation time, diabetes, extent of resection, combined resection, stage, preoperative albumin, perioperative blood transfusion, preoperative PNI, LCR and LMR. Among the seven machine learning models, the MGA-XGBoost model performed best. Among the seven machine learning models, the MGA-XGBoost model performed best, with AUC of 0.936, ACC of 0.889, recall of 0.6, F1-score of 0.682, and precision of 0.79 on the validation set. Diabetes had the greatest influence on the internal structure of the model. Conclusion This study proves that the MGA-XGBoost model incorporating comprehensive inflammation indicators can predict postoperative infectious complications in patients with gastric cancer.
Objective To discuss the pathogeny， treatment and prophylactic measures of postcholecystectomy syndrome (PCS). Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed. Results Etiological factors were found in 131 patients: one hundred and twelve cases were due to the reasons of biliary system, including bile duct residual stones after cystic resection， the injury bile duct stenosis， a long residual cystic canal， nipple benign stricture, bile duct tumor etc; Nineteen examples were due to other reasons, including gallbladder stone merger reflux gastritis, gastroduodenal ulcer， diverticulum beside duodenal nipple, and so on, which resulted in the symptoms un-release after cystic resection. Nineteen cases were not found organic lesion. In ones whose etiological factors were definite, 117 cases were treated with different surgeries according to different etiological factors; another 33 cases were treated with conservative treatment. Total 145 cases were followed up, and 139 cases in them were cured or relieved at different degrees. Conclusion Careful preoperative examination, normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.
Objective To explore the risk factors of postoperative anxiety in patients with pancreatic cancer undergoing total pancreatectomy. Methods A total of 31 patients who underwent total pancreatectomy for pancreatic cancer between July 2011 and December 2016 were collected and analyzed in this retrospective study. The patients’ postoperative Self-Rating Anxiety Scale scores were collected, and the exposure factors were analyzed to identify the risk factors of postoperative anxiety through univariate analysis and multiple logistic regression analysis by SPSS 21.0 statistical software. Results In the 31 patients, there were 17 males and 14 females, with an average age of (66.16±9.09) years, an average body mass index of (21.11±3.10) kg/m2, and an average postoperative hospital stay of (14.58±7.47) days. There were 23 patients (74.2%) with postoperative anxiety, and 30 patients (96.8%) with hyperglycosemia required insulin therapy. The total perioperative mortality was 3.2%. In the univariate analysis, age (P=0.012), smoking history (P=0.043), preoperative diabetes mellitus (P=0.012), postoperative bile leakage (P=0.043), and postoperative abdominal infection (P=0.026) were related factors of the postoperative anxiety. In the multiple logistic regression analysis, patients without preoperative diabetes was an independent risk factor of postoperative anxiety (P=0.013). Conclusions For patients undergoing total pancreatectomy, it is needed to pay attention to the patients’ postoperative psychological conditions and assess the postoperative anxiety, especially for those without preoperative diabetes. To improve the life quality and long-term survival of these patients, health education and psychological intervention are needed.
Objective To understand the urination of orthopedic patients after the catheter is removed, and to explore the influencing factors of urodynia. Methods Convenient sampling was used to select 160 patients who underwent surgical treatment in the Department of Orthopedics of West China Hospital of Sichuan University from May to July 2020. Questionnaires were used to investigate the patients’ urination, and a logistic regression model was used to analyze the factors affecting the patients’ urodynia. Results A total of 157 patients urinated by themselves after the catheter was removed, with 102 cases of dysuria. Logistic regression results showed that male [odds ratio (OR)=0.282, 95% confidence interval (CI) (0.092, 0.863), P=0.027], Huaxi Emotional-Distress Index score [OR=1.407, 95%CI (1.124, 1.760), P=0.003] and intraoperative fluid infusion [OR=1.001, 95%CI (1.000, 1.002), P=0.014] were the influencing factors of urodynia. Conclusion Most orthopedic patients can urinate on their own after the catheter is removed, but more than half of the patients experience urodynia during the first urination. Gender, mental status and intraoperative fluid infusion are the influencing factors of urodynia after urinary catheter removal after surgery. Clinical nursing staff should identify these influencing factors as soon as possible and carry out targeted interventions to improve the success rate of patients with urination after removing the catheter, reduce the incidence of urodynia, and promote the recovery of patients.
