Collection of digestive tissues
Digestive tissues will be collected from participants undergoing scheduled (non-emergent) gastrointestinal surgery.
|
The surgeon will resect a sample (approximately 1-5 cm x 1-5 cm) of healthy tissue from the distal margins of the segment and at least 4 cm from the diseased area.
The specimen for research will be obtained from the tissue that would ordinarily be removed during surgery.The tissue collected for our research purposes will be only remnant tissue which is discarded by the surgeon during the surgical intervention and has no diagnostic clinical value.
