BACKGROUND: An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. METHODS: We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. RESULTS: The patient underwent venography confirming superior vena cava stenosis...

AIMS: Skeletal muscle lipid stores and mitochondrial function have been appointed as key players in obesity-induced insulin resistance. However, there are conflicting reports in the literature based on in vitro quantitative measurements. Here we test the hypothesis that it is not the quantity but the quality that matters. METHODS: The present study combines quantitative and qualitative structural measurements of lipid stores and mitochondrial dynamics in skeletal muscle from lean subjects, and subjects with morbid obesity, with and without type 2 diabetes, before and after gastric bypass surgery...

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) reduces body weight and the comorbidities associated with obesity. The aim of this study was to evaluate whether glucose and lipid profiles were maintained during a 5-year follow-up period after RYGB. SUBJECTS AND METHODS: Anthropometric and laboratory data from 323 patients who had undergone this operation were analyzed. Differences in laboratory variables between the baseline and 12, 24, 36, 48 and 60 months postoperatively (PO) were assessed using a one-way ANOVA test to compare the three groups...

OBJECTIVES: Jejuno-ileal bypass (JIB) was a kind of bariatric surgery performed from 1960s to 1980s, able to induce sustainable weight loss by creating a surgical short bowel syndrome. MATERIALS AND METHODS: We report a case of an octogenarian woman who underwent in the early eighties this kind of surgery with consequent 40 kg weight loss. After 27 years, she first developed a reversible metabolic cardiomyopathy that began with signs and symptoms of heart failure...

BACKGROUND: Results of a previous study revealed an over-ordering of blood products for cardiac surgery and led to the creation of a new blood ordering algorithm. This follow-up study has been conducted to evaluate improvement in ordering practices. METHODS: Retrospective data were collected for 171 patients who underwent coronary artery bypass grafting or valve surgery from March 2015 to March 2016 to determine the crossmatch-to-transfusion ratio (C:tx) and potential cost savings...

BACKGROUND: For many years, the Roux-en-Y Gastric Bypass (RYGB) was considered a good balance of complications and weight loss. According to several short-term studies, single anastomosis duodenal switch or stomach intestinal pylorus sparing surgery (SIPS) offers similar weight loss to RYGB with fewer complications and better diabetes resolution. No one has substantiated mid-term complication and nutritional differences between these two procedures. This paper seeks to compare complication and nutritional outcomes between RYGB and SIPS...

BACKGROUND: Several studies have found that metabolic surgery can significantly improve glucose homeostasis; however, the intrinsic mechanisms remain unclear. Accumulating evidence suggests that duodenal bypass plays a crucial role in the treatment of type 2 diabetes mellitus (T2DM). Here, we aimed to evaluate the effect of duodenal reflux on glucose metabolism in T2DM. METHODS: A high-fat diet and low-dose streptozotocin (STZ) administration were used to induce T2DM in male rats, which were assigned to three experimental groups: sham operation (SO; n = 10), new duodenal-jejunal bypass (NDJB; n = 10), and new duodenal-jejunal bypass with a tube (NDJBT; n = 10)...

BACKGROUND: Bariatric surgery contributes to the improvement in glucose metabolism that may be related to a postoperative increase in serum bile acids (BAs). Three commonly used types of bariatric procedures, laparoscopic sleeve gastrectomy (LSG) (without creation of a bile loop), Roux-en-Y gastric bypass (RYGB), and omega-loop gastric bypass (OLGB) (with creation of shorter 100-150 cm and longer 200-280 cm bile loops, respectively), differ in their effects on glycemic control. The aim of the study was to compare the effects of various bariatric procedures on serum BA concentration and glucose homeostasis...

While percutaneous catheter closure proves an effective treatment for secundum atrial septal defect (ASD2), some child patients require surgical closure. We assessed the risks associated with isolated surgical ASD2 closure by reviewing the outcomes of 120 children operated on between 1999 and 2011 (mean age 4.6 ± 3.9 years, mean weight 17 ± 12 kg). Direct sutures were performed in 4% and patch closures in 96%. The mean cardiopulmonary bypass duration was 38 ± 14 min, aortic cross-clamp time 19 ± 9 min, intensive care unit length of stay 1...

BACKGROUND: Strategies for cardio-protection are essential in coronary artery bypass graft surgery. The authors explored the relationship between cardioplegia volume, left ventricular mass index and ischemia time by means of the infused cardioplegia index and its relationship with post-operative low cardiac output syndrome. DESIGN: All patients undergoing coronary artery bypass graft surgery between January 2013 and December 2015 were included. Low cardiac output syndrome was defined according to criteria of the SEMICYUC's consensus document...

OBJECTIVE: Retrograde cerebral perfusion is becoming less frequently used as a method of neuroprotection during aortic surgery. The present meta-analysis aims to compare outcomes after arch surgery with hypothermic circulatory arrest versus hypothermic circulatory arrest + retrograde cerebral perfusion. METHODS: Electronic searches were performed using 7 databases from their inception to September 2016. Relevant comparative studies that included patient groups who underwent aortic arch surgery using hypothermic circulatory arrest with continuous retrograde cerebral perfusion or hypothermic circulatory arrest alone were identified, and data were extracted by 2 independent researchers...

OBJECTIVE: Introduction: Nowadays operative treatment of corrosive esophageal strictures remains one of the difficult and unsolved problems in surgery. The level of postoperative complications such as anastomotic leak (develops in 7-30% of cases), infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive strictures is still rather high. The aim of our work was to improve the results of surgical treatment of patients with corrosive esophageal strictures by analyzing and refining on conservative therapy options as well as differentiated approach to each operative treatment method...

Occlusive artery disease (CAD) is the leading cause of death worldwide. Bypass graft surgery remains the most prevalently performed treatment for occlusive arterial disease, and veins are the most frequently used conduits for surgical revascularization. However, the clinical efficacy of bypass graft surgery is highly affected by the long-term potency rates of vein grafts, and no optimal treatments are available for the prevention of vein graft restenosis (VGR) at present. Hence, there is an urgent need to improve our understanding of the molecular mechanisms involved in mediating VGR...

Background: Popliteal artery entrapment syndrome (PAES) is a very rare pathology that can cause lower extremity ischemia in healthy young people. Anomalous anatomic relationships between the popliteal artery (PA) and the surrounding musculo-tendinous structures cause PAES. We present 31 patients with PAES in 35 limbs that were treated surgically in our clinic within a 12-year period. Patients and Methods: From 2001 to 2015, 31 patients (mean age: 32 ± 7.4 years) underwent surgery for PAES...

Endovascular techniques have revolutionized the management of deep venous occlusive disease. Open surgery, however, is still required for cases that prove refractory to endovascular interventions. The surgical management of deep venous occlusive disease typically involves venous bypass. Preoperative planning before open venous surgery relies upon dynamic imaging to clarify the location and severity of venous obstruction, the assessment of infrainguinal reflux, and the delineation of bypass origination and target vessels...

Feline obstructive ureteral disease will likely remain a common and frustrating cause of critical illness in cats for the foreseeable future. Since many cats are uraemic and cardiovascularly unstable secondary to obstructive nephropathy, prompt recognition using clinical intuition, blood work and diagnostic imaging is essential to make a timely diagnosis and decision about timing for intervention, if indicated. Multiple surgical and interventional procedures exist for the management of feline ureteral obstructions but there is no ideal technique and all currently available procedures carry risk of infection, re-obstruction, urine leakage and the need for additional procedures in the future...

Considerable variation in the use and duration of antiplatelet medications during the perioperative and postoperative care of patients undergoing coronary artery bypass grafting (CABG) reflects limited studies focused directly on these patients as well as variation in the results reported. In this review we will highlight the incidence and mechanisms of graft closure as well as the evidence in support of antiplatelet therapy that is balanced by the impact of antiplatelet therapy on the risk of bleeding to provide recommendations for the use of antiplatelet therapy in patients undergoing CABG...

Ameliorated renal function has been reported after bariatric surgery, but the mechanisms underlying this phenomenon are not well-studied. To investigate whether the long non-coding RNA (lncRNA) MALAT1 mediates the amelioration of diabetic nephropathy after duodenal-jejunal bypass (DJB) surgery, rats were assigned randomly into four groups: diabetic (DM) group, DM with DJB surgery group, DM with sham surgery group, and healthy control group. Food intake, body weight, oral glucose tolerance test (OGTT), urine albumin excretion rate (UAER), and glomerular filtration rate (GFR) were measured and histological examination of renal sections was performed...

Morbidly obese patients often elect for Roux-en-Y gastric bypass (RYGB), a form of bariatric surgery that triggers a remarkable 30% reduction in excess body weight and reversal of insulin resistance for those who are type II diabetic. A more complete understanding of the underlying molecular mechanisms that drive the complex metabolic reprogramming post-RYGB could lead to innovative non-invasive therapeutics that mimic the beneficial effects of the surgery, namely weight loss, achievement of glycemic control, or reversal of non-alcoholic steatohepatitis (NASH)...
