Brief Summary:
In this research study, biopsy samples will be collected to provide more insight into the underlying cause of the motility disorders, help direct further investigation into the cause of the underlying condition, provide future prognosis and predict response to gastric electrical stimulation (GES).

Condition or disease
Gastroparesis

Detailed Description:
Biopsies will be collected from patients that have been diagnosed with gastroparesis (having nausea, retching, bloating and fullness of stomach) and are undergoing surgery for the GES implantation. These patients will serve as our study group population. Biopsy samples of those who do not have gastroparesis but are undergoing surgery on the digestive system will be collected after the patients consent to be on the trial. These patients will serve as our control group population. Detailed medical history will be collected and the study group patients will be asked to complete two questionnaire to assess the severity of the symptoms. They will be followed in the clinic at 6, 12, 18 and 24 months post implantation.

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.




Primary Outcome Measures :
  1. 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



Secondary Outcome Measures :
  1. 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

  2. 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


  3. 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.


Biospecimen Retention:   Samples Without DNA
Full thickness biopsies of Gastric body and proximal jejunum obtained.
