Abstract:
Using traditional techniques in novel ways often can improve management of common surgical problems. Additionally, established products may find new utility when deployed in a slightly different fashion to enhance patient care in a clinically relevant way. This article describes endoscopic placement of radiopaque markers into the proximal small intestine as a means to evaluate motility in a focused fashion. A method to delineate the location of dysmotility in a patient with several potential sites is described. This technique is safe, feasible, reasonably inexpensive, and is easily performed by a skilled endoscopist. Moreover, this technique has the added benefit of providing functional data in a timely fashion.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
