Brief summary

The purpose of this study is to help scientists understand how the gut senses ingested nutrients and what kind of processes take place for their absorption in order to establish the association with diabetes and other metabolic diseases Scientists need human specimens to study.

Interventions

PROCEDURECollection of digestive tissues

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.
