[Colon cancer after colon interposition for oesophageal replacement]

Area of Science:

• Gastroenterology
• Surgical Oncology
• Oesophageal Surgery

Background:

• Corrosive oesophageal injuries can necessitate complex reconstructive surgery.
• Long-term complications of oesophageal reconstruction are not well-documented.
• This case highlights a delayed malignancy in a transposed colonic segment.

Observation:

• A patient with a history of severe corrosive oesophageal, stomach, and laryngeal injuries underwent multiple reconstructive procedures, including ileocolon transposition.
• Forty-four years post-injury, an ulcerated adenocarcinoma developed at the skin-colon anastomosis in the transposed segment.
• The adenocarcinoma was surgically resected.

Findings:

• Successful resection of a late-developing colon adenocarcinoma in a transposed colonic segment.
• Restoration of swallowing function was achieved through microvascular transplantation of an isolated jejunal segment.
• This case demonstrates a rare long-term complication of oesophageal reconstruction.

Implications:

• Highlights the potential for delayed malignancies in transposed gastrointestinal segments.
• Emphasizes the importance of long-term surveillance after complex oesophageal reconstruction.
• Suggests that transposed colonic segments may be susceptible to adenocarcinoma development years after surgery.
