Gastric interposition following transhiatal esophagectomy: CT evaluation
Radiology
|April 1, 1985
Summary
Computed tomography (CT) is superior to barium studies for detecting recurrent cancer after transhiatal esophagectomy (THE). CT also aids in managing mediastinal abscesses, offering a valuable tool for post-surgical assessment.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Background:
- Transhiatal esophagectomy (THE) with gastric interposition offers lower morbidity than transpleural esophagectomy.
- Barium examination is the traditional method for detecting complications after THE.
Purpose of the Study:
- To evaluate the utility of computed tomography (CT) scans in detecting postoperative complications following THE.
- To compare the efficacy of CT scans versus barium studies in identifying recurrent neoplasm and other complications.
Main Methods:
- Retrospective review of CT scans from 21 patients who underwent THE.
- Correlation of CT findings with clinical status and barium study results.
Main Results:
- CT detected local mediastinal recurrent neoplasm in seven patients; barium studies missed recurrence in three within 2 weeks.
- CT accurately delineated a mediastinal abscess for percutaneous drainage.
- Water-soluble contrast/barium studies are better for anastomotic leaks.
Conclusions:
- CT is the preferred imaging modality for detecting local recurrence and distant metastases after THE.
- CT is valuable for managing mediastinal abscesses post-THE.
- Understanding normal CT anatomy post-esophagectomy is crucial to avoid interpretation errors.
