Document Summary

Large intestine begins right lower quadrant at the ileocecal valve: 1. 5m long, 6 cm diameter. Ugi & small bowel typically combined (follow through- sbft) Small bowel only series- not the stomach/first part of duodenum. All these methods are therapeutic vs diagnostic. Functional study of motility - small bowel. Small bowel obstruction obstructions can be functional or mechanical.
