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.

【 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 ．
Objective To analyze the reasons, methods of treatment, and effects on prognosis of vitreous hemorrhage after vitrectomy in patients with diabetic retinopathy. Methods The clinical data of 98 patients (122 eyes) with diabetic retinopathy (VI stage) who had undergone vitrectomy were retrospectively analyzed. Results Post-vitrectomy vitreous hemorrhage (gt;grade 2) was found in 25 eyes with the occurrence of 20.5%, in which the hemorrhage occurred 1 week after the surgery in 8 eyes, 1 week to 1 month in 6 eyes, and more than 1 month in 11 eyes. In the 25 eyes, C3F8 tamponade eyes occupied 31.1%, silicone oil tamponade eyes occupied 6.1%, air tamponade eyes occupied 33.3%, and infusion solution tamponade eyes occupied 26.3%. Peripheral fibrovascular proliferation was found in 9 eyes. In the 3 eyes with silicone oil tamponade, the hemorrhage was absorbed in 2, and epiretinal membrane was found in 1 which was moved when the silicon oil was taken out. In the 22 eyes without silicone oil tamponade, the hemorrhage was absorbed in 6 and aggravated in 2 without any timely treatment, neovascular glaucoma occurred in 1, and wide vitreo-retinal proliferation and retinal detachment was observed in 1 with the visual acuity of no light perception. Operations such as fluid-air exchange, vitrectomy were performed on 14 eyes 2 weeks after the hemorrhage absorption stopped. Recurrent vitreous hemorrhage was not found in 12 eyes after single operation. At the end of the follow up period, the visual acuity was no light perception in 3 eyes, hand moving in 2 eyes, counting finger-0.1 in 10 eyes, under 0.3 in 4 eyes, and over 0.3 in 6 eyes. Conclusion Most of the patients with vitreous hemorrhage after vitrectomy due to DR had peripheral fibrovascular proliferation. The visual prognosis after re-operation is good.

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 compare the effect of intravenous and epidural analgesia on postoperative complications after abdominal and thoracic surgery. Methods A literature search was conducted by using computerized database on PubMed, EBSCO, Springer, Ovid, and CNKI from 1985 to Jan 2009. Further searches for articles were conducted by checking all references describing postoperative complications with intravenous and epidural anesthesia after abdominal and thoracic surgery. All included randomized controlled trials (RCTs) were assessed and data were extracted by the standard of Cochrane systematic review. The homogeneous studies were pooled using RevMan 4.2.10 software. Results Thirteen RCTs involving 3 055 patients met the inclusion criteria. The results of meta-analyses showed that, a) pulmonary complications and lung function: patient-controlled epidural analgesia can significantly decrease the incidence of pneumonia (RR=0.66, 95%CI 0.53 to 0.83) and improve the FEV1 (WMD=0.17, 95%CI 0.05 to 0.29) and FVC (WMD=0.21, 95%CI 0.1 to 0.32) of lung function after abdominal and thoracic surgery, but no differences in decreasing postoperative respiratory failure (RR=0.77, 95%CI 0.58 to 1.02) and prolonged ventilation (RR=0.75, 95%CI 0.51 to 1.13) compared with intravenous analgesia; b) cardiovascular event: epidural analgesia could significantly decrease the incidence of myocardial infarction (RR=0.58, 95%CI 0.35 to 0.95) and arrhythmia (RR=0.64, 95%CI 0.47 to 0.88) than the control group, but could not better reduce the risk of heart failure (RR=0.79, 95%CI 0.47 to 1.34) and hypotension (RR=1.21, 95%CI 0.63 to 2.29); and c) Other complications: epidural and intravenous analgesia had no difference in decreasing the risk of postoperative renal insufficient (RR=0.78, 95%CI 0.53 to 1.14), gastrointestinal hemorrhage (RR=0.78, 95%CI 0.49 to 1.23), infection (RR=0.89, 95%CI 0.70 to 1.12) and nausea (RR=1.03, 95%CI 0.38 to 2.81). Conclusions Epidural analgesia can obviously decrease the risk of pneumonia, myocardial infarction and severe arrhythmia, and can improve the lung function after abdominal or thoracic surgery.
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 assess the safety for removing nasogastric tube(NGT)within postoperative 24 h in Whipple pancreaticoduodenectomy (PD)patients. MethodsThe clinical data of 310 patients performed classic Whipple PD from January 2008 to March 2013 in this hospital were analyzed retrospectively. The patients were divided into early (≤24 h after operation)removing NGT group and late( > 24 h after operation)removing NGT group according to the time of NGT duration. The ratio of NGT reinsertion, time of solid diet tolerance, hospital stay, mortality, and major complications associated with PD were compared between two groups. Results①The demography and preoperative comorbidities characteristics were similar(P > 0.05).②There was no statistical difference of ratio of NGT reinsertion between two groups(P=0.450).③The differences of rates of major complications associated with PD and mortality were not statistically different(P > 0.05)by univariate analysis, but the rate of total complications in the early removing NGT group was significantly lower than that in the late removing NGT group (P=0.014)by multivariate analysis.④The average time of solid diet tolerance(P=0.013)and average hospital stay(P < 0.001)in the early removing NGT group were significantly shorter than those in the late removing NGT group. ConclusionFor patients comfort, NGT following PD should be removed as early as possible even immediately after extubation for selective patients.
Objective To observe the efficacy of vitreoretinal surgery on proliferative diabetic retinopathy (PDR) in patients with type 1 and type 2 diabetes mellitus (DM). Methods Retrospectively analyzed the clinical data of 451 patients with DM (71 with type 1 and 380 with type 2) who underwent PDR from June 1999 to October 2003. The follow-up period was at least 14 months with the average of 29 months. The pre-and post-operative visual acuity, progression and regression of iris neovascular (INV), neovascular glaucoma (NVG), and the reattached and being attached rate of retina were observed and compared between the two groups. The effect of different types of DM on vitreoretinal surgery for PDR were observed. Results The preoperative data showed that the number of type 1 DM patients with severe PDR was more than the type 2 DM patients: the rate of grade VI PDR, the visual acuity lower than 0.1, INV and NVG were all higher that which in type 1 DM patients. The increased ratio of postoperative visual acuity was 64.8% (46/71) in type 1 DM patients and 72.4% (275/380) in type 2 DM patients (P=0.196). There were 75.0% patients with PDR combined with rubeosis iridis in type 1 DM group and 60.0% in type 2 DM group (P＝0.678);the rate of new rubeosis iridis after surgery was 6.3% in type 1 DM group and 5.6% in type 2 DM group (P＝0.822). The intraocular pressure of NVG eyes were all controlled effectively in both type 1 and type 2 DM groups, and INV did not regressed only in one case in type 1 DM group. In the patients with preoperative retinal detachment at the grade VI of PDR, the rate of retinal reattachment after on off operation was 87.2% in type 1 DM group and 89.8% in type 2 DM (P＝0.611); the rate of retina being-attachment after one-off surgery were 90.1% in type 1 DM group and 93.4% in type 2 DM group, respectively (P＝0.323). Conclusion There was no obvious difference of surgical efficacy on the two types of DM in patients with PDR. (Chin J Ocul Fundus Dis,2007,23:248-251)
