Major complications of coloscopy: bleeding and perforation
The American Journal of Digestive Diseases
|March 1, 1975
Summary
Colonic procedures have a 1.3% complication rate, including perforation and bleeding. Most complications occur early in a physician's experience, highlighting the need for standardized coloscopy training programs.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- The frequency and types of complications from diagnostic colonoscopy and colonic polypectomy are not well-documented.
- Assessing these risks is crucial for patient safety and procedural improvement.
Purpose of the Study:
- To determine the morbidity and mortality rates associated with colonoscopy.
- To identify factors contributing to complications and propose preventive measures.
Main Methods:
- A statewide survey of 28 physicians performing colonoscopies was conducted.
- Data from 1,106 colonoscopic procedures were analyzed for complications.
Main Results:
- A 1.3% complication rate was observed, including 9 colonic perforations and 5 episodes of bleeding.
- A mortality rate of 0.09% was recorded due to an unrecognized sigmoid colon perforation.
- 12 out of 14 reported complications occurred during the initial 40 procedures of a physician's experience.
Conclusions:
- Colonoscopy and colonic polypectomy carry a significant complication risk, particularly in early physician experience.
- Establishing standardized training programs for colonoscopy is essential to mitigate morbidity and mortality.
