Adenocarcinoma in the Intrathoracic Transposed Colon

Area of Science:

• Gastroenterology
• Surgical Oncology
• Gastrointestinal Surgery

Background:

• Esophagectomy with colon interposition is a common procedure for benign esophageal diseases, offering patients long-term survival.
• While generally safe, the interposed colon segment can be susceptible to neoplastic changes over time.

Observation:

• A 65-year-old female patient presented with an obstructing adenocarcinoma in a left colon segment used for interposition 37 years after the initial esophagectomy.
• The patient had undergone the esophagectomy with colon interposition for lye-induced strictures.

Findings:

• Endoscopic evaluation revealed an obstructing adenocarcinoma within the interposed colon.
• The tumor was completely removed using endoscopic techniques.
• The patient has remained disease-free and in good general condition with a regular diet for 5 years post-procedure.

Implications:

• This case underscores the importance of long-term surveillance for patients with colon interposition after esophagectomy.
• Endoscopic management is a viable option for early-stage adenocarcinoma in interposed colonic segments.
• Surgical reconstruction with colon interposition can lead to favorable long-term outcomes, even with the potential for secondary malignancies.
