【 Abstract 】 Objective To investigate the features and risk factors of bacterial infection after orthotopic liver transplantation (OLT) and summarize the experiences for prevention and treatment of infection. Methods The clinical materials of 79 patients underwent OLT from December 2004 to January 2007 were reviewed. The incidence and sites of postoperative bacterial infections as well as species of bacteria and the situation of drug resistance were retrospectively analyzed. Results Thirty-two (40.5%) out of 79 patients developed bacterial infections. Infection mainly occurred in lung, abdominal cavity and blood, which were mainly caused by Escherichia coli, staphylococcus aureus, klebsiella pneumoniae, staphylococcus epidermidis and enterococcus bacteria. The main risk factors included delayed restoration of gastrointestinal function (gt;5 d), poorly preoperative liver function (Child C grade), hypoproteinemia and persistent postoperative hyperglycemia (gt;11.0 mmol/L). Perioperative decontamination in digestive tract was a protective factor in the prevention of bacterial infection. Conclusion Bacterial infection is one of the most severe complications after OLT. Therefore, it is very important to remove those risk factors, make early diagnosis and take effective treatment ．
ObjectiveTo explore the effects of modified telescopic embedding anastomosis in surgical treatment of esophageal and cardiac carcinoma. MethodsWe retrospectively analyzed the clinical data of 160 patients with esophageal or cardiac cancer undergoing surgery in our group from January 2014 through May 2015. There were 119 males and 41 females with a mean age of 61.6±7.1 years. Sixty-four patients received Sweet esophagectomy and 96 patients underwent minimally invasive Mckeown esophagectomy, and all the patients received end to side mechanical anastomosis. The patients were divided into a modified group and a traditional group according to the embedding types. There were 34 males and 12 females aged 61.7±6.4 years in the modified group undergoing modified telescopic embedding. There were 85 males and 29 females aged 62.2±7.5 years in the traditional group undergoing traditional interrupted horizontal mattress suture embedding. The anastomostic time and postoperative complications were compared between the two groups. ResultsCompared with the traditional group, obviously lower incidence of anastomotic fistula (0.0% vs. 12.3%, χ2=4.478, P=0.013), shorter anastomosis time (28.9±2.9 min vs. 30.0±3.1 min, t=-1.983, P=0.049), but a higher incidence of anastomotic stenosis (30.4% vs. 3.5%, χ2=23.799, P=0.000) in the modified group were found. There were no significant differences in the incidences of pulmonary complications, cardiovascular complications, laryngeal recurrent nerve injury, or perioperative mortality between the two groups (P>0.05). ConclusionModified telescopic embedding anastomosis is safe and feasible in surgical treatment of esophageal and cardiac carcinoma, and can effectively reduce the incidence of anastomotic fistula.
ObjectiveTo observe the clinical characteristics of patients with familial vitreous amyloidosis (FVA) and the efficacy of vitrectomy (PPV) and the occurrence of complications. MethodsA retrospective clinical study. From June 2009 to March 2020, 32 eyes of 18 patients from 3 FVA families who were diagnosed and treated by PPV at Department of Ophthalmology of Jiaxing TCM Hospital were included in the study. Among them, there were 12 males with 22 eyes and 6 females with 10 eyes. The average age of onset was 42.28±3.25 years; the average duration of disease was 3.75±3.93 years. All the affected eyes underwent best corrected visual acuity (BCVA) and B-mode ultrasound examination. A logarithmic visual acuity chart was used in the BCVA examination, which was converted to the logarithmic minimum angle of resolution (logMAR) visual acuity when recorded. The average logMAR BCVA of the affected eye was 1.72±0.53; the intraocular pressure was less than 21 mm Hg (1 mm Hg=0.133 kPa). The vitreous body of the affected eye was obviously cloudy. All the affected eyes underwent standard three-channel PPV through the flat part of the ciliary body, and vitreous specimens were collected for pathological examination during the operation. Peripheral venous blood of probands from 3 families was collected, and the whole exome gene sequencing was performed. The follow-up time after surgery was ≥6 months. The patient's clinical characteristics, fundus lesions in PPV, changes in BCVA after surgery, and complications was observed. One-way analysis of variance or t test was performed for measurement data comparison; χ2 test was performed for count data comparison. ResultsThe vitreous body of the affected eye showed gray-white dense and thick flocculent changes, and the posterior capsule attached to the lens showed "foot disc-like" turbidity; later the lens was mainly cystic opacity. Pathological examination of the vitreous body showed positive staining of Congo red; under a polarized light microscope, it showed apple green dots and sheet-like birefringence. The genetic test results showed that there was a c.307G>C (p.Gly103Arg) missense mutation in the TTR gene of the proband in Family 2. Peripheral retinal hemorrhages in 4 eyes (12.5%, 4/32), retinal tears in 5 eyes (15.6%, 5/32), retinal degeneration in 4 eyes (12.5%, 4/32), retinal detachment were found in PPV 3 eyes (9.4%, 3/32). The vitreous body was filled with C3F8 and silicone oil respectively for 2, 1 eye. Six months after the operation, the logMAR BCVA of the affected eye was 0.39±0.32, which was significantly higher than that before the operation, and the difference was statistically significant (t=15.131, P=0.000). After the operation, high intraocular pressure occurred in 2 eyes (6.3%, 2/32), secondary glaucoma in 1 eye (3.1%, 1/32), retinal detachment in 2 eyes (6.3%, 2/32), neovascular glaucoma (NVG) in 2 eyes (6.3%, 2/32), cataract in 10 eyes (31.3%, 10/32). ConclusionThe vitreous body of FVA eyes are gray-white dense, thick and flocculent, attached to the posterior lens capsule, showing "foot disc-like" turbidity; PPV treatment can effectively improve the BCVA of the FVA eyes; secondary glaucoma, secondary retinal detachment, NVG can occur after surgery.
Objective To analyze the clinical risk factors of the occurrence of severe proliferative vitreoretinopathy (PVR) after scleral reattachment surgery. Methods A total of 4031 eyes of 4031 consecutive patients with reghmatogenous retinal detachment (RRD) and PVR (grade C1 or less), on whom the scleral buckling was performed, were retrospectively studied. Twenty-two clinical charac teristics of the patients (including the ocular tension, condition of lens and vitreous, characte ristics of retinal detachment, whether or not with choroidal detachment, et al) were recorded.In 4031 patients, 2660 were followed up for more than 3 months, and 72 (in PVR group) of the 2660 patients underwent the second surgery (vitre oretinal surgery) because of the occurrence of postoperative seve re PVR; in the other 2588 patients, 72 (72 eyes) with retinal reattachment for more than 3 months were selected randomly as the control. The data were analyzed in SPSS (10.0) software. Results Logistic regression analysis revealed that the significant risk factors for PVR were incomplete posterior vitreous detachment ( P＜0.001), intraocular pressure lt;7 mm Hg（1 mm Hg=0.133 kPa, P＜0.002）, and large retinal tear (gt;2 DD,P＜0.005). Conclusion Incomplete posterior vitreous detachment, intraocular pressure lt;7 mm Hg and large retinal tear of the patient with RRD may be the major risk factors for PVR.

Objective To investigate the pathogenesis of deep vein thrombosis (DVT) after total hip arthroplasty (THA) and the preventive effectiveness of low molecular weight heparin (LMWH). Methods The occurrence condition of DVT in 90 cases undergoing THA treated with LMWH between February 2003 and March 2004 was restrospectively analyzed. Among 90 cases, 39 were treated with LMWH at a dose of 5 000 U/day (high dose group) and 51 at a dose of 2 500 U/day (low dose group). Another 90 cases undergoing THA without LMWH treating between February 2002 and February 2003 were used as control group. There was no significant difference in gender, age, illness cause, course of disease, or the type of prosthesis among 3 groups (P gt; 0.05). Results DVT occurred in 19 cases (21.1%) of control group, in 2 cases (5.1%) of high dose group, and in 5cases (9.8%) of low dose group, showing significant differences between two treated groups and control group (P lt; 0.05), but no significant difference between two treated groups (P gt; 0.05). There was no significant difference in gender, age (gt; 65 years and ≤ 65 years), pathogen (trauma and bone disease) of each group, as well as of the same type patients within 3 groups (P gt; 0.05). The DVT incidence rate in the patients with bone cement artificial joint was significantly higher than that in the patients with non-bone cement artificial joint (P lt; 0.05), but there was no significant difference in the same type patients within 3 groups (P gt; 0.05). The postoperative blood loss in high dose group, low dose group, and control group was (463.5 ± 234.2), (342.4 ± 231.6), and (288.2 ± 141.6) mL; showing no significant difference between the high and low dose groups, between low dose and control groups (P gt; 0.05), while showing significant difference between high dose and control groups (P lt; 0.05). Conclusion The DVT incidence rate in THA patients with bone cement artificial joint is high; LMWH can reduce the DVT incidence rate and has good safety.
Objective To investigate the effect of CT-guided percutaneous lung puncture biopsy and nursing of postoperative complications. Methods We retrospectively analyzed the clinical data of 522 patients who underwent CT-guided percutaneous lung biopsy between May and August 2014 in the Department of Lung Cancer Center. Effect of the puncture biopsy, postoperative complications and nursing measures were summarized. Results After surgery, 507 cases of diagnosis were confirmed, 10 were not confirmed, and 5 cases of puncture were unsuccessful. There were 203 cases of complications, including 122 cases of pneumothorax (23.4%), 56 of hemoptysis 56 (10.7%), 20 of pleural effusion (3.8%), 4 of pleural reaction (0.8%), and 1 of mediastinal emphysema (0.2%). All the above complications were cured after positive symptomatic treatment and nursing care. There were no such complications as severe hemopneumothorax, severe hemoptysis or needle tract metastasis. Conclusions CT-guided percutaneous lung puncture biopsy is a safe and reliable method, but there are some patients with complications. Observation and postoperative care are particularly important. Timely detection and positive care will achieve satisfactory results.
Abstract: Objective [WTBZ]To evaluate the longterm effects of preoperative glucocorticoid treatment on postoperative complications and survival rates for patients receiving cardiac surgery. Methods [WTBZ] We selected 57 patients including 22 males and 35 females at an average age of 52.3±11.2 years in the First Hospital of China Medical University who took steroids for a long time because of various combined diseases from September 2002 to August 2009 in the trial group, and we chose another 171 patients including 62 males and 109 females at an average age of 53.6±9.2 years who were hospitalized at the same time and had comparative basic features in the control group. There was no statistical difference between the two groups in age, gender, and organ function. Different kinds of surgeries including coronary artery bypass grafting, heart valvuloplasty or valve replacement, coronary artery bypass grafting combined with heart valve replacement, and congenital heart disease surgery were performed on the patients. The proportion of surgeries carried out was similar in the two groups. Postoperative complications were compared between the two groups, and survival rates at the end of 6 months and one year followup were observed. Results [WTBZ]There was no statistical difference between the two groups in complications with respect to cardiopulmonary bypass (CPB) time (t=1.27, Pgt;0.05), reoperation for excessive postoperative bleeding (χ2=0.03, P=0.87), sternal and mediastinal infection (χ2=0.04, P=0.84), stroke (χ2=0.07, P=0.79), and gastrointestinal tract complications (χ2=2.89, P=0.09). The incidence of ventricular arrhythmia and requirement for intraaortic balloon pump in the trial group was higher, but no statistical difference was detected (χ2=2.24, P=0.13; χ2=2.20, P=0.14, respectively). Patients in the trial group were more likely to require prolonged ventilation (t=2.32, Plt;0.05), had higher rate of atrial fibrillation (χ2=4.09, P=0.04), and higher inhospital mortality (χ2=5.35, P=0.02). The sixmonth and oneyear survival rates were 0.79±0.10 and 0.73±0.12, respectively for the trial group, 0.94±0.09 and 0.86±0.10, respectively for the control group. Conclusion Longterm steroid treatment leads to higher atrial fibrillation incidence, longer ventilation time and increases the mortality rate following cardiac surgery.
ObjectiveTo systematically evaluate the influence of posterior mediastinal and retrosternal route on the incidence of complications in patients with esophageal carcinoma after esophagectomy. MethodsA systematic literature search for studies which were published on PubMed, EMbase, CBM, VIP was performed from database establishment to April 2014. We included randomized controlled trials and case control studies related to the influence of two routes on the incidence of complications of patients with esophagectomy. We assessed the methodology quality of included researches, and extracted data. RevMan 5.2 was used for meta-analysis. ResultsA total of 23 studies including 7 randomized controlled trials and 16 case control studies were included in this study. Meta-analysis showed that there was statistically significant difference in case control studies related to anastomotic leakage between two groups[OR=0.39, 95%CI (0.30, 0.50), P < 0.01]. However, no statistical difference in anastomotic stricture was observed between the two groups[randomized controlled trials:RR=0.80, 95%CI (0.49, 1.30), P=0.36; case control studies:OR=0.64, 95%CI (0.40, 1.03), P=0.07]. And there was no statistical difference in cardiac complications[randomized controlled trials:RR=0.70, 95%CI (0.46, 1.06), P=0.09; case control studies:OR=1.13, 95%CI (0.70, 1.81), P=0.62]. There was also no statistical difference in pulmonary complications[randomized controlled trials:RR=1.27, 95%CI(0.92, 1.75), P=0.14; case control studies:OR=0.91, 95%CI (0.66, 1.27), P=0.59]. Besides, there was also no statistical difference in postoperative mortality[randomized controlled trials:RR=0.47, 95%CI (0.19, 1.16), P=0.10; case control studies:OR=0.18, 95%CI (0.03, 1.01), P=0.05]. ConclusionFor patients with esophageal carcinoma undergoing esophagectomy and reconstruction, the incidence of anastomotic leakage was significantly lower with posterior mediastinal route than that of retrosternal route.
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.
ObjectiveTo observe the efficacy of "Fuchuang Xunxi Formula" at different concentrations on patients after mixed hemorrhoidectomy.
