- The position in which a patient is treated for pelvic irradiation has been shown to have dramatic significance in regard to the volume of small bowel within the treatment field. Previous studies in the literature have repeatedly supported the fact that volume may be the leading factor in both acute and chronic morbidity. We have prospectively evaluated and treated 30 patients utilizing a custom-made polyurethane foam and styrofoam "belly board" with a dropout cut from the level of the xyphoid process to the superior border of the treatment field, specifically designed to allow maximal superior and anterior displacement of small bowel by bladder distention and gravity, while allowing reliable daily reproducibility, accurate immobilization and equally important, increased patient comfort and compliance. By evaluating all patients (in both the supine position alone, and prone in the "Belly Board") with a dedicated treatment planning CT scanner, we have been able to achieve 80-100% reduction in the volume of small bowel within the radiation portals. We will discuss data on the technical set-up, cost, and variations which allow the "Belly Board" to be specifically tailored for use when treating other intraabdominal sites. This technique is simple, inexpensive, highly reproducible, and permits maximal bowel displacement outside the treatment fields. © 1990.
