The pansigmoidoscope: one year's experience in a gastrointestinal diagnostic unit
Journal of Clinical Gastroenterology
|March 1, 1979
Summary
The Olympus pansigmoidoscope offers a safe and effective tool for examining the lower colon, proving most useful for diagnosing and monitoring inflammatory bowel disease and investigating rectal bleeding. Its adoption led to a significant decrease in the use of older sigmoidoscope and colonoscope models.
Area of Science:
- Gastroenterology
- Endoscopy
- Medical Devices
Background:
- The Olympus pansigmoidoscope was introduced for routine use in May 1976.
- Previous diagnostic tools included rigid sigmoidoscopes and MB2 colonoscopes.
Purpose of the Study:
- To evaluate the utility and safety of the Olympus pansigmoidoscope for routine lower gastrointestinal examinations.
- To compare the usage frequency of the pansigmoidoscope with older endoscopic devices.
Main Methods:
- 265 examinations were performed using the Olympus pansigmoidoscope.
- Patient preparation involved tap water enemas, with exceptions for known inflammatory bowel disease.
- Procedures included biopsies and polypectomies; no sedation was administered.
Main Results:
- Average examination distance was 49 cm, with an average procedure time of 8 minutes.
- The pansigmoidoscope was highly beneficial for inflammatory bowel disease, hematochezia, abnormal barium enemas, left-sided polypectomy, diarrhea, and guaiac-positive stools.
- No complications were reported.
- There was a 50% decrease in rigid sigmoidoscope use and a 98% decrease in MB2 colonoscope use.
Conclusions:
- The Olympus pansigmoidoscope is a safe and effective instrument for lower gastrointestinal endoscopy.
- Its routine use has led to a substantial reduction in the utilization of older sigmoidoscopy and colonoscopy technologies.
- The device is particularly valuable for specific diagnostic indications within gastroenterology.
