Nephrolithiasis after bariatric surgery: A review of pathophysiologic mechanisms and procedural risk.

Obesity alone is a known risk factor for nephrolithiasis, and bariatric surgery has been linked to a higher incidence of post-operative new-onset nephrolithiasis. The mean interval from bariatric surgery to diagnosis of nephrolithiasis, ranges from 1.5 to 3.

Large bowel obstruction complicating a posttraumatic diaphragmatic hernia.

Posttraumatic diaphragmatic hernia is a rare cause of large bowel obstruction, and can present weeks or years after the initial trauma. Herein, we report the case of a 28-year-old man who presented with signs and symptoms of bowel obstruction nine months after he had a stab wound to his left chest. Chest radiography showed multiple air‑fluid levels in the right upper quadrant, an air-fluid level in the left thoracic cavity and significant free air under the diaphragm.
