Life threatening rupture of the diaphragm after Covid 19 pneumonia: a case report.

Background: The incidence of diaphragmatic rupture is low; however, it may be life threatening. Normally caused by blunt trauma, some cases are reported after pulmonary infections with extensive coughing. Covid 19 causes pulmonary infections and pneumonia and has been associated with weakening of the diaphragm after prolonged ventilation.

Sarcopenia and primary tumor location influence patients outcome after liver resection for colorectal liver metastases.

Introduction: Right-sided and left-sided colorectal cancer (CRC) is known to differ in their molecular carcinogenic pathways. The prevalence of sarcopenia is known to worsen the outcome after hepatic resection. We sought to investigate the prevalence of sarcopenia and its prognostic application according to the primary CRC tumor site.

Increased hospital costs are associated with low skeletal muscle mass in patients undergoing elective open aortic surgery.

Objective: Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access.

Effectiveness of porcine dermal collagen in giant hernia closure in patients with deleterious fascia constitution after orthotopic liver transplantation.

Incisional hernias (IHs) occur universally after orthotopic liver transplantation (OLT). This study aimed to investigate the effectiveness of porcine dermal collagen (PDC) as a closing aid in giant hernias after OLT in a prospective trial. If direct closure (DC) was not feasible due to the hernia size and abdominal wall constitution, a PDC mesh was implanted.

The role of serum albumin in the prediction of malnutrition in patients at least five yr after heart transplantation.

Objectives: Malnutrition after heart transplantation (HTX) is related to graft sclerosis. The risk for malnutrition is often underestimated by conventional measurements. We aimed to compare these with objective assessors for malnutrition.

Hepatobiliary transporter expression and post-operative jaundice in patients undergoing partial hepatectomy.

Background And Aims: Post-operative hyperbilirubinaemia in patients undergoing liver resections is associated with high morbidity and mortality. Apart from different known factors responsible for the development of post-operative jaundice, little is known about the role of hepatobiliary transport systems in the pathogenesis of post-operative jaundice in humans after liver resection.

Methods: Two liver tissue samples were taken from 14 patients undergoing liver resection before and after Pringle manoeuvre.

Working conditions and trainee shortage in operative disciplines--is our profession ready for the next decade?

Background: Increasing concern has been expressed worldwide on the problem of finding young doctors to enter a training programme in an operative speciality.

Materials And Methods: A survey comprising 22 questions on working conditions and job satisfaction was placed on the homepage of the Austrian Society of Surgery; 667 questionnaires were completed.

Results: The question whether surgery is threatened by a trainee shortage was answered with "yes" by 68%.

Prospective study comparing standard and robotically assisted laparoscopic cholecystectomy.

Background And Aims: Laparoscopic surgery has become the treatment of choice for cholecystectomy. Many studies showed that while this approach benefits the patient, the surgeon faces such distinct disadvantages as a poor ergonomic situation and limited degrees of freedom with limited motion as a consequence. Robots have the potential to overcome these problems.

Accuracy of preoperative routine MRI for hepatic lesion detection.

Background: The outcome of liver resections depends on complete removal of all detectable foci. Our aim was to determine the value of preoperative routine magnetic resonance imaging (MRI) for complete detection of hepatic lesions.

Methods: We compared 271 lesions seen on MRI in 182 patients to intraoperative findings (including intraoperative ultrasonography) and histology.

Is intraoperative ultrasonography during partial hepatectomy still necessary in the age of magnetic resonance imaging?

Background/aims: The aim of our study was to determine if intraoperative ultrasonography is still necessary in the time of magnetic resonance imaging.

Methodology: Our prospective study comprised 122 patients (82% with malignant tumors) undergoing partial hepatectomy with preoperative magnetic resonance imaging, done at the same institution using a standardized liver protocol as well as intraoperative ultrasonography performed in a systematic fashion.

Results: Seventeen additional malignant lesions in 16/122 patients (13.
