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.

Low skeletal muscle mass outperforms the Charlson Comorbidity Index in risk prediction in patients undergoing pancreatic resections.

Introduction: Low skeletal muscle mass is a known predictor of morbidity and mortality in patients undergoing major pancreatic surgeries. We sought to combine low skeletal muscle mass with established risk predictors to improve their prognostic capacity for postoperative outcome and morbidity.

Methods: As established parameters to predict preoperative mortality risk for patients, the ASA classification and the Charlson Comorbidity Index (CCI) were used.

Laparoscopic versus open appendectomy for complicated appendicitis in high risk patients.

Introduction: Laparoscopic appendectomy is widely used for the treatment of complicated appendicitis. Its use in patients with high operative risk is still on debate. The aim of the presented study was to investigate the benefits of laparoscopic appendectomy in patients with high peri- and postoperative risk factors.
