Biliothoracic Fistula after Microwave Ablation of Liver Metastasis : Literature Review.

Microwave ablation is a safe and effective interventional approach, widely used in the treatment of unresectable primary or metastatic hepatic lesions. Thoracobiliary fistula is a rare postablation complication that can be treated with a conservative or surgical approach. We reviewed aetiology, pathogenesis, clinical picture, diagnostic possibilities, and therapeutic options for biliothoracic fistula developed after microwave ablation of liver metastasis.

Abnormal colonic propagated activity in patients with slow transit constipation and constipation-predominant irritable bowel syndrome.

Background: The pathophysiological basis of constipation is still unclear, and the role of colonic dysfunction is debated, especially in irritable bowel syndrome. Objective data are quite scarce, especially concerning colonic propulsive activity.

Aims: To evaluate high- and low-amplitude colonic propulsive activity in constipated patients (slow-transit type and irritable bowel syndrome) in comparison with normal controls.
