Distinct patterns of myogenic motor activity identified in isolated human distal colon with high-resolution manometry.

Background: Colonic high-resolution manometry (HRM) has been used to reveal discrete, propagating colonic motor patterns. To help determine mechanisms underlying these patterns, we used HRM to record contractile activity in human distal colon ex vivo.

Methods: Surgically excised segments of descending (n = 30) or sigmoid colon (n = 4) were immersed in oxygenated Krebs solution at 36°C (n = 34; 16 female; 67.

Gas in gallbladder-gallstone ileus?

Gallstone ileus is an uncommon presentation among acute surgical patients. Its diagnosis is often delayed due to its non-specific clinical presentation. We report the case of an 81-year-old gentleman with a 2-day history of small bowel obstruction (SBO).
