    Colon interposition surgery for esophageal cancer, involving irradiation and esophagectomy, presents risks like anastomotic leaks (31.8%) and strictures (59.1%). Ischemia is a common complication, but most defects heal spontaneously.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Radiology

    Background:

    • Esophageal cancer treatment often requires complex surgical reconstruction.
    • Colon interposition is a technique used for esophageal replacement after esophagectomy.

    Purpose of the Study:

    • To evaluate the roentgenographic and surgical outcomes of colon interposition in patients with esophageal carcinoma.
    • To identify common complications and their management in this patient cohort.

    Main Methods:

    • Retrospective review of 44 patients undergoing colon interposition.
    • Staged therapy included mediastinal irradiation, colonic interposition, and total esophagectomy.
    • Analysis of surgical complications, including luminal patency, conduit integrity, and mortality.

    Main Results:

    • 42 of 44 patients had esophageal carcinoma.
    • Complications included anastomotic narrowing (29.5%), proximal anastomotic leaks (31.8%), and fistulous tracts (34%).
    • Strictures (59.1%) and colonic graft ischemia (5 instances) were observed; surgical mortality was 6.8%.

    Conclusions:

    • Colon interposition for esophageal cancer has significant complication rates, particularly related to anastomotic integrity and ischemia.
    • Most leaks and fistulae showed spontaneous healing or resolved with simple drainage.
    • Radiographic evaluation with single contrast barium is recommended, especially when extravasation is suspected.
