Purpose A study to show the ultrasonographic appearances of the ileocecal valve in normal and abnormal conditions. Methods and Materials The study consisted of two groups comprising 92 patients. Group A:We performed ultrasound in 50 cases which had been prepared for colonoscopy by mechanical bowel wash. We demonstrated an ileocecal valve having a slit/oval appearance. Group B: It comprised of 42 cases with varied pathologies, showing a diseased ileocecal valve. Graded sonographic compression technique was used, with an Aloka Prosound SSD-4000 machine using a convex probe of 2.5-6 MHZ and a linear probe of 8-13 MHZ frequency.

Results The ileocecal valve was seen in 92 patients and in 50 cases the valve showed a normal slit appearance in 30 cases and oval in 20, which was confirmed to be normal on subsequent colonoscopy. In the remaining 42 patients, the valve showed an irregular, thickened, edematous and nodular appearance in Tuberculosis(12cases) and Crohn's disease(8), edematous valve with normal contour in Ileocolitis(4), smooth hypoechoic mass like appearance in Lymphoma(6), irregular shape with destruction of valve in Adenocarcinoma(6) {1}, edematous valve with a normal contour and a featureless ascending colon in Ulcerative colitis(6). These findings were confirmed by colonoscopic biopsy, and surgery in a few cases.

Conclusion The abnormal ultrasound findings of the ileocecal valve in various diseases, correlated well with surgical and colonoscopic findings. Based on the above, it can be said that the usage of ultrasound is a novel way of looking at the ileocecal valve in both normal and abnormal conditions.
