Unusual Cause of Intestinal Obstruction

Abstract

Acute adult intestinal invagination is rare and often secondary to an organic lesion. It accounts for less than 5% of AIOs in adults. Grelic invagination on polyp is exceptional. We report a case of grelo-grelic polyp invagination in a 19-year-old male. The clinical presentation was that of an occlusive syndrome. The abdominal scanner confirmed the occlusion, specified its seat. The procedure consisted of a resection of 12 cm with the invagination collar and termino-terminal anastomosis. The anatomopathological examination confirmed the diagnosis of a benign tubular adenoma type tumour in low-grade dysplasia. Conclusion: Acute intestinal occlusion by grelic invagination on polyp is rarely encountered in adults. Its symptomatology is non-specific. Its diagnosis is facilitated by abdominal computed tomography. Surgical excision is the treatment of choice.
