This retrospective study compared the immediate post-operative (first month) and mid-term (up to 5 years post-operation) results of 22 patients with isolated ventricular septal defects who underwent surgical correction with bovine pericardium with 57 similar patients who received a polytetrafluoroethylene (PTFE) patch. There were no cases of early (in the first month) mortality in either group and the 3-month post-operative echocardiographical studies showed no evidence of calcification or aneurysm formation around the patch. Recurrent ventricular septal defects due to dehiscence of the patch occurred in the early follow-up period in four patients who had the PTFE patch but this was not statistically significant. Annual echocardiographical examination revealed some calcification in both groups. We conclude that although there are no significant differences between the two materials in outcome after ventricular septal defects closure, we prefer bovine pericardium because of its handling characteristics, elasticity and the lower risk of endocarditis.

Curative resection has to be the goal of surgical management in patients with gastric remnant cancer. Concerning clinician should be sceptical about a newly developing cancer in order to detect it in an early stage and enhance resectability.

SummaryBackgroundProanthocyanidin is a bioflavonoid known to have protective effect against oxidative injury. We investigated the cardioprotective effect of proanthocyanidin.Material/MethodsThirty-two Rattus Norvegicus rats were categorized equally as the control group (CG), proanthocyanidin group (PCG), ischemia group (IG) and proanthocyanidin-treated group (PCT). Rats in CG and IG were fed standard rat food and PCG and PCT were fed standard rat food plus proanthocyanidin (100 mg/kg/day twice a day by oral gavage) for 3 weeks. In CG and PCG the myocardial samples were prepared immediately, and in IG and PCT hearts were placed in transport solution and kept at 4°C for 5 hours, then prepared for evaluation. Malondialdehyde (MDA) level, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities were measured.ResultsMDA levels were significantly higher in IG and PCT than in CG and PCG. The activity of SOD was significantly lower in IG and higher in PCG than in the other groups. The activity of GPx was significantly lower in IG than in the other groups. The activities of CAT were significantly lower in IG and PCT than in the other groups and were significantly lower in IG than PCT. Histopathologic evaluation revealed normal findings in CG and PCG. While ischemic injury was observed in IG, the content of muscle fibers was better preserved in PCT.ConclusionsProanthocyanidin may have a protective effect on myocardial ischemic injury.

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirtyseven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

BackgroundThe aim of the present study was to investigate the cardioprotective effect of Taurine on the donor hearts during cold ischemic period.Methods32 rats were divided into four groups (sham, taurine, ischemia, treatment group, 8 rats in each). All rats were fed with rat food for three weeks. Taurine and treatment groups were given a 200 mg/kg/day dose of Taurine by oral gavage besides rat feed. Cardiectomy was performed in all rats after three weeks. In ischemia and treatment groups, harvested hearts were kept in 0.9% sodium chloride at +4 degrees C for 5 hours. Tissue samples were taken from left ventricle in all groups. These samples were evaluated by histopathologic and biochemical examination.ResultsIn the present study results of the biochemical and histopathological examination reveals the protective effects of Taurine. As a marker of lipid peroxidation, Malondialdehyde (MDA) levels in ischemia group were significantly higher than both Sham and Taurine groups. MDA values were recorded; 3.62 ± 0.197 in the sham group, 2.07 ± 0.751 in the Taurine group, 9.71 ± 1.439 in the ischemia group and 7.68 ± 1.365 in the treatment group. MDA levels decreased in treatment group. (p < 0.05) In accordance with MDA findings, while superoxide dismutase and glutathione peroxidase levels decreased in ischemia group, they increased in treatment group. (p < 0.05) There was no differences in Catalase (CAT) enzyme level between treatment and ischemia group (p = 1.000). CAT level results were recorded; 7.08 ± 0.609 in the sham group, 6.15 ± 0.119 in the Taurine group, 5.02 ± 0.62 in the ischemia group, and 5.36 ± 0.384 in the treatment group. Less intracellular edema and inflammatory cell reaction were observed in histologic examination in favor of treatment group. (p < 0.01)ConclusionTaurine decreased myocardial damage during cold ischemic period following global myocardial ischemia.
