Manometrically guided colon insufflation during double-contrast barium enemas.
The double-contrast enema's potential for high accuracy depends in part on consistently good inflation of the colon. However, optimal inflation is often not obtained because of deflation during filming, underinflation because of fear of perforating the colon, or patient discomfort. To help meet the dual requirements of ensuring consistently good bowel inflation while avoiding over-inflation, we have designed a modified insufflator which incorporates a manometer and allows accurate readings of intraluminal large-bowel pressures during or following insufflation. In more than 3000 examinations using this method we have experienced no complications.
