Meckel's diverticulum. Investigation of 600 patients in Japanese literature
Abstract:
A total of 600 cases, comprising 4 of our cases and 596 others in Japan, was analyzed, and the diagnosis of Meckel's diverticulum was made in only 34 of them. The rate of diagnosis was 5.7 per cent, which is very low. The most common complication of this disease was intestinal obstruction, the second most common was intussusception, the third was inflammation, and the fourth was rectal bleeding. Ectopic tissue, present in ninety-three patients, consisted of ectopic gastric mucosa in fifty-eight. 99mTc-P scanning was performed on fifteen patients. In twelve of them ectopic gastric mucosa was observed. However, it was not found in three, all of whom had false-positive scans.
Insights
Diagnosis of Meckel
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Meckel's diverticulum is a congenital anomaly of the small intestine.
- It is the most common congenital malformation of the gastrointestinal tract.
- Complications include intestinal obstruction, intussusception, inflammation, and rectal bleeding.
Purpose of the Study:
- To evaluate the diagnostic rate of Meckel's diverticulum.
- To identify common complications associated with Meckel's diverticulum.
- To assess the utility of 99mTc-P scanning in diagnosing ectopic gastric mucosa.
Main Methods:
- Retrospective analysis of 600 cases diagnosed with Meckel's diverticulum in Japan.
- Review of patient records to identify complications and presence of ectopic tissue.
- Analysis of 99mTc-P scan results in patients with suspected ectopic gastric mucosa.
Main Results:
- A low diagnostic rate of 5.7% (34 out of 600 cases) for Meckel's diverticulum was observed.
- Intestinal obstruction was the most frequent complication, followed by intussusception, inflammation, and rectal bleeding.
- Ectopic gastric mucosa was present in 58 of 93 patients with ectopic tissue; 99mTc-P scanning correctly identified ectopic gastric mucosa in 12 of 15 patients, with 3 false-positive scans.
Conclusions:
- The diagnosis of Meckel's diverticulum is frequently missed, highlighting a need for improved diagnostic strategies.
- Understanding common complications is crucial for timely intervention.
- 99mTc-P scanning is a valuable tool for detecting ectopic gastric mucosa, although false positives can occur.
