COLONOSCOPIC DIAGNOSIS OF LYMPHOID HYPERPLASIA CAUSING RECURRENT INTUSSUSCEPTION - REPORT OF A CASE

This paper describes a 6-year-old boy with recurrent ileocecal intussu sception due to lymphoid hyperplasia in the terminal ileum, which was diagnosed preoperatively by colonoscopy, At the age of 3 years, he dev eloped diarrhea and a tender abdominal mass, He was diagnosed as havin g intussusception by ultrasound and was treated by hydrostatic barium enema, After resolution, he had three recurrent episodes of intussusce ption, A contrast barium enema revealed a small mass in the ileocecal region, Colonoscopy showed several exaggerated folds of the terminal i leum and a biopsy showed lymphoid hyperplasia, Because the repeated in tussusception seemed to have been caused by the lymphoid hyperplasia i n the terminal ileum, he underwent an ileocecal resection without any subsequent recurrence, Based on the above findings, we conclude that a colonoscopy may thus be useful both for diagnosing lymphoid hyperplas ia in the terminal ileum as a cause of recurrent intussusception and f or deciding how to manage it.
