Complicated Diverticulitis: A Rare Long-Term Complication After Esophagectomy With Colon Interposition.

Abstract

Colon interposition, a rare esophageal reconstructive procedure, can lead to late complications such as diverticulitis in the transplanted colon segment. This case involves a 65-year-old man who presented with a neck swelling 60 years after a colon interposition following caustic ingestion. A diagnosis of diverticulitis with an abscess was confirmed on a computed tomography scan after an initial diagnosis of diverticulitis, and subsequent abscess drainage was performed. Despite the development of a colocutaneous fistula, it closed spontaneously after eight weeks. The pathophysiology involves altered colonic conditions postsurgery. Management includes antibiotics and drainage, but treatment for such fistulas remains uncertain, requiring a tailored approach.
