bougie calibration
Pronunciation: BOO-zhee kal-ih-BRAY-shun
The process of using graduated dilators to measure and standardize the diameter of surgical connections in bariatric procedures.
Full Definition
Bougie calibration involves using a series of graduated cylindrical dilators to accurately measure the internal diameter of surgical anastomoses or gastric pouches in bariatric surgery. This technique ensures standardized sizing across procedures and helps prevent both excessive restriction and inadequate weight loss. The bougie serves as a guide during stapling to maintain consistent luminal diameter, particularly important in sleeve gastrectomy where the final gastric tube diameter directly impacts restriction and emptying. Proper calibration requires understanding of bougie French sizing, where each French unit equals 1/3 millimeter in diameter.
Usage
Usage note: Critical for standardizing restriction; French sizing system applies.
