Primary extraskeletal osteosarcoma of small bowel mesentery presenting with acute bowel obstruction.

Extraskeletal osteosarcoma of the small bowel mesentery is an exceedingly rare condition. It is an aggressive malignant neoplasm of mesenchymal origin characterized by osteoid formation. Final diagnosis is often made by histopathological analysis.

Sequential organ failure assessment score is superior to other prognostic indices in acute pancreatitis.

Background: Acute pancreatitis (AP) is a common surgical condition, with severe AP (SAP) potentially lethal. Many prognostic indices, including; acute physiology and chronic health evaluation II score (APACHE II), bedside index of severity in acute pancreatitis (BISAP), Glasgow score, harmless acute pancreatitis score (HAPS), Ranson's score, and sequential organ failure assessment (SOFA) evaluate AP severity and predict mortality.

Aim: To evaluate these indices' utility in predicting severity, intensive care unit (ICU) admission, and mortality.

Are traditional scoring systems for severity stratification of acute pancreatitis sufficient?

Backgrounds/aims: Ranson's score (RS) and Glasgow score (GS) have been utilized to stratify the severity of acute pancreatitis (AP). The aim of this study was to validate RS and GS for stratifying the severity of acute pancreatitis and audit our experience of managing AP.

Methods: We conducted a retrospective review of patients treated for AP from July 2009 to September 2016.

Is emergency right hemicolectomy still associated with significant morbidity and mortality rates? An institution's experience of 207 cases over 6 years.

Introduction: Emergency right hemicolectomy has been associated with dismal outcome. But, data in Asians is lacking as pathologies that require emergency right hemicolectomy may differ from that in the Western population. The aims of our study were to review our institution's experience with emergency right hemicolectomies and to identify factors that could predict the per-operative outcome.
