Use of self-expanding covered stent and negative pressure wound therapy to manage late rectal perforation after injury from an improvised explosive device: a case report.

Blast injuries, caused by explosions accompanied by high-pressure waves, produce tissue damage in the acute period, followed in the later period by circulatory disorders due to vascular endothelial damage and related tissue necrosis. Blunt rectal perforation is rare and difficult to diagnose. In the acute period following blast pelvic injuries, the main objectives are to stop bleeding, minimise contamination and preserve the patient's life.

Biliary fistula after treatment for hydatid disease of the liver: when to intervene.

Aim: To determine the outcome of patients with biliary fistula (BF) after treatment for hydatid disease of the liver.

Methods: Between January 2000 and December 2010, out of 301 patients with a diagnosis of hydatid cyst of the liver, 282 patients who underwent treatment [either surgery or puncture, aspiration, injection and reaspiration (PAIR) procedure] were analysed. Patients were grouped according to the presence or absence of postoperative biliary fistula (PBF) (PBF vs no-PBF groups, respectively).
