A rare case of massive colonic distention secondary to undiagnosed colon adenocarcinoma

Introduction

Colonic distention is a critical condition arising from various abdominal pathologies. It necessitates both timely diagnosis and intervention to prevent severe complications such as ischemia or perforation.

Case

We present the case of a 69-year-old male with an 8-month history of progressive abdominal distention, minimal bowel movements, occasional vomiting, and significant weight loss. Imaging revealed high-grade colonic dilatation with a severe diffuse stool burden. Consequently, a self-expandable metallic stent (SEMS) was placed successfully, relieving the obstruction and serving as a bridge to elective surgical management.

Conclusion

This case highlights the subtle and insidious progression of symptoms in some patients with malignant colonic obstruction, sometimes leading to a delayed presentation and diagnosis. It emphasizes the role of SEMS as an effective, minimally invasive intervention as a bridge for definitive surgical management. Early recognition and intervention in cases of progressive colonic distention are critical to optimizing patient outcomes.
