INTRODUCTION: Over 75% of ingested foreign bodies pass the gastrointestinal tract without any complications. Blunt foreign bodies may lead to a disruption of the intestinal passage, mainly in the area of the ileocoecal opening. The size of the reported foreign bodies varies considerably. The aim of this study was the anatomic investigation to clarify the possible causes of obstruction and its influence on the diameter of the ileocoecal opening. MATERIAL AND METHOD: We investigate anatomically and describe the ileocoecal opening on the basis of 27 specimens. RESULTS: We found not a flap mechanism but a valve mechanism in the ileocoecal junction. The median diameter of the formalin-fixated specimens was 10.9 mm respectively 21.8 mm according to an assumed correction factor of 2. The cause for intestinal obstruction most probably is the ingestion of blunt, angular foreign bodies in the ostium ileale. CONCLUSION: The intraindividual differences as well as the considerable size of foreign bodies that pass the ileoceocal opening support the hypothesis, that the complications described are more a consequence of an ingestion of blunt, cornered foreign bodies in the ostium ileale independent ofn the size of the ileocoecal opening itself.
OBJECTIVE: The aim of this study is to determine the colon types, developmental change of the colon morphology during the fetal period. METHODS: The study was realised on 131 human fetuses (male 69, female 62) ages between 10 and 40 weeks, which have no external pathology and anomalies. The colon types were evaluated in two parts. As the first part, the colon part between the ileal orifice and sigmoid colon was typed. The sigmoid colon was typed as the second part. The macroscopic diameters of parts of the colon and the thicknesses of wall layers of ascending and descending colons were measured under the light microscope. RESULTS: For the proximal part of the colon, there were seven types of colon, and there were five types for the sigmoid colon. For the first part, transverse type colon was a rare type during the fetal period (3%). The oblique type colon was observed mostly in the first and second trimester during the fetal period. Adult type colon was the most common type in the third trimester and full-term groups. The pendulous type colon was observed mostly in the third trimester. The development of the haustra and tenia coli in the first trimester was quite slow, but later the development increased more and more, and during the full-term period, the haustra and tenia coli could be seen clearly. CONCLUSION: The percentage distribution of the colon types between the trimesters was significant. It was observed that the maturation of haustra and tenia coli started from the ascending colon and progressed towards the sigmoid colon. The thickness of the tunica mucosa layer both in the ascending and in descending colon part increased considerably in the middle of the second trimester.
