Adult ileocecocolic intussusception with mucocele of the appendix: a rare presentation

Intussusception is a condition in which part of the intestine telescopes into an adjacent segment, causing bowel obstruction. It is common in children but rare in adults, comprising only 5% of all intussusceptions and 1-5% of adult intestinal obstructions. Adult cases often have identifiable causes, making early diagnosis and intervention crucial. Appendiceal mucocele is an exceptionally rare lead point for intussusception.

A 53-year-old male presented with abdominal distension and severe periumbilical pain, accompanied by nausea and vomiting. Physical examination revealed tenderness but no mass. Imaging studies identified ileocecocolic intussusception with an appendiceal mucocele as the lead point. Exploratory laparotomy and right limited hemicolectomy were performed. Histopathology confirmed a low-grade appendiceal mucinous neoplasm. The patient recovered uneventfully and was discharged in stable condition.

Adult intussusception is often triggered by bowel wall lesions or luminal irritants that disrupt normal peristaltic activity. Diagnosis is challenging due to non-specific symptoms and requires advanced imaging techniques. Surgical intervention is crucial, especially when there are concerns about malignancy. Prompt treatment is essential to prevent severe complications. Appendiceal mucocele, a rare lead point, necessitates careful surgical management to avoid rupture and ensure successful outcomes.

This case emphasizes the rarity and complexity of ileocecocolic intussusception with an appendiceal mucocele, highlighting the need for prompt diagnosis and surgical intervention. Early detection is crucial to prevent serious complications and improve patient outcomes.
