Group/Cohort |

Study Group
Patients undergoing surgical full thickness biopsy of the stomach and/or proximal jejunum for the clinical evaluation of GI neuromuscular disorder.
|
Control Group
Patient undergoing esophagectomy, sleeve gastrectomy for obesity, Roux-en-Y gastric bypass, Whipple surgery, transplant surgery. Patients who are organ donors and undergoing surgery are also part of the control group. |
- Clinical data at 4 time periods for study patents will be measured [ Time Frame: 2 years ]
Follow up clinical data will be obtained before, 6 months, 1.5 years, and 2 years after the full thickness biopsy.
Follow up clinical data PAGI-SYM Overall Treatment Effect by Patient Overall Treatment Effect by Physician
- Positive Clinical Outcome to surgical implantation of GES measured by GCSI [ Time Frame: 6 months ]Responders will be defined as >50% improvement of the GCSI total score at 6 month after surgical GES
- Neuromuscular pathology results of the gastric body and proximal jejunum wil be compared between the following groups [ Time Frame: 6 months ]
Patients with gastroparesis from type 1 DM versus patients with idiopathic gastroparesis.
Patients with gastroparesis from type I DM versus gastroparesis from type 2 DM
- Correlation of Pathology Results and Questionnaire [ Time Frame: 6 months ]Neuromuscular pathology results of the gastric body and proximal jejunum will be correlated with the following: Symptom severity (GCSI total score), predominant symptom presentation, severity of delayed gastric emptying.
