Percutaneous retrieval of a biliary stent after migration and ileal perforation

We present a case of a migrated biliary stent that resulted in a distal small bowel perforation, abscess formation and high grade partial small bowel obstruction in a medically stable patient without signs of sepsis or diffuse peritonitis. We performed a percutaneous drainage of the abscess followed by percutaneous retrieval of the stent. The entero-peritoneal fistula closed spontaneously with a drain in place. We conclude, migrated biliary stents associated with perforation distal to the Ligament of Trietz (LOT), may be treated by percutaneous drainage of the abscess and retrieval of the stent from the peritoneal cavity, even when associated with a large intra-abdominal abscess

Catechol-O-Methyltransferase Genotype Predicts Pain Severity in Hospitalized Burn Patients

Increasing evidence suggests that stress system activation after burn injury may contribute to burn-related pain. If this is the case, then genetic variations influencing the function of important stress system components, such as the enzyme catechol-O-methyltransferase (COMT), may predict pain severity after thermal burn injury
