Retroperitoneal blue cell round tumor (Ewing sarcoma in a 35 years old male)- case report.

Introduction: Ewing sarcoma is a highly aggressive tumor. It's common presentation is primary bone tumor, but very rarely as soft tissue sarcoma both of which are under the spectrum of Ewing sarcoma family of tumors (EFT).

Case Presentation: A 35 years old male who presented with advanced locally spreading tumor.

Intracardiac Penetrating Injury with Right Femoral Artery Embolism due to Blast Injury.

Embolization due to blast injury with projectiles entering the bloodstream from the heart is a rare event that is unlikely to be suspected during the initial assessment of trauma patients. We report a case in which a missile penetrating the heart chambers managed to embolize and occlude the right common femoral artery. This was successfully managed by means of a multidisciplinary approach that included exploration, cardiorrhaphy, and embolectomy.

Preoperative endoscopy localization error rate in patients with colorectal cancer.

Background: Preoperative repeat endoscopy in colorectal cancer (CRC) patients is considered by many to be an integral component of surgical planning. Little is known, however, about the utility of re-endoscopy.

Methods: A retrospective review of 342 consecutive patients undergoing elective surgical resection for CRC from January 2008 to December 2011 was performed.

Gallstone ileus obstructing within an incarcerated lumbar hernia: an unusual presentation of a rare diagnosis.

We describe an unusual case of a 74-year-old woman who presented with signs and symptoms of small-bowel obstruction and a clinically appreciable, irreducible, left-sided lumbar hernia associated with previous iliac crest bone graft harvesting. Palpation of the hernia demonstrated a small, firm mass within the loops of herniated bowel. CT scanning recognised an intraluminal gallstone at the transition point, establishing the diagnosis of gallstone ileus within an incarcerated lumbar hernia.

Preoperative re-endoscopy in colorectal cancer patients: an institutional experience and analysis of influencing factors.

Background: This study serves to establish the re-endoscopy rate in patients undergoing surgery for colorectal cancer (CRC) at a tertiary academic center and to identify significant factors that may influence the decision for preoperative re-endoscopy.

Methods: A retrospective review of 341 consecutive patients undergoing elective surgical resection for CRC was performed from January 2008 to December 2011. Descriptive statistics were used to define the patient population and to establish the institutional re-endoscopy rate.
