BACKGROUND/AIMS: Anastomotic failure occurs in up to 10% of patients following anterior resection. Selective use of a loop ileostomy may reduce the septic consequences of anastomotic leak. The use of gastrograffin enema to confirm the anastomotic integrity prior to ileostomy closure is still controversial. Our aim was to determine the ...

BACKGROUND & AIMS: Bloating represents a frequent gastrointestinal symptom, but the pathophysiologic mechanism responsible for its onset is still largely unknown. Patients very frequently attribute the sensation of bloating to the presence of excessive bowel gas, but not all patients with gas-related symptoms exhibit increased intestinal production of gas. It ...
