ILEAL DUPLICATION CYST IN THE ELDERLY COMPLICATED BY APPENDICITIS: A RARE CASE REPORT AND REVIEW OF LITERATURE

•Duplication cysts seen commonly in the pediatric population is a rare entity in the elderly.•Surgical resection is necessary due to possible complications.•Laparoscopic management aids early recovery and minimum morbidity. Gastrointestinal duplication cysts are rare, generally found in infants and young adults. Adult presentation is rare. We present an elderly lady who presented with right iliac fossa pain. Imaging showed a terminal ileal duplication cyst. Laparoscopic right hemicolectomy was done. Histopathology confirmed ileal duplication cyst with reactive appendicitis. Surgical resection is deemed appropriate management due to known complications like obstruction, hemorrhage, perforation and malignant degeneration. Resection of only the cyst is adequate in completely isolated cases. However, others require resection of adjoining small bowel. We highlight the rare occurrence in elderly and its management laparoscopically.
