Objectives
Definition Epidemiology & Impact Diagnosis & Differential Management
Pharmacologic Surgical Gastric Electrical Stimulation
-
Definition
Objective delay in gastric emptying Absence of gastric outlet obstruction or
ulceration Symptoms
Postprandial fullness (early satiety) Nausea Vomiting Bloating MEG abdominal pain

Epidemiology
Prevalence: 24.2/100,000 9.6/100,000 male 37.8/100,000 female
Incidence 1996-2006 2.4/100,000 male 9.8/100,000 female
-
Epidemiology
Incidence in Olmsted County, MN DM1 4.8% DM2 1% Idiopathic 0.1%
DM gastroparesis Typically develops after DM 10 years Tends to persist despite improved glycemic control More likely to have cardiovascular disease, HTN,
retinopathy

Epidemiology
QOL Hospitalizations have increased since 2000
Poor glycemic control Infection Noncompliance or intolerance of medications
Delayed gastric emptying study predicts: Morbidity Hospitalizations ED and doctor visits

Etiology
Idiopathic (IG) 36% DM (DG) 29% Postsurgical (PSG) 13% Parkinsonism Amyloidosis Paraneoplastic syndrome (SCLC, ovarian, etc.) Scleroderma Mesenteric ischemia
-
Etiology
Extrinsic: Post surgical vagal nerve injury
Fundoplication Peptic ulcer surgery Roux-en-Y bariatric surgery
Roux-en-Y stasis syndrome: Vagotomy predisposes to slowemptying from gastric remnant delayed transit of Rouxalimentary limb

Etiology
Extrinsic: Pharmacological blockade
GLP-1 analogs Exenatide (nausea 43% vomiting 12.8%), liraglutide NOT dipeptidyl peptidase IV inhibitors: sitagliptin, saxagliptin,
linagliptin, alogliptin Amylin analogs
pramlintide Narcotics - -opioid agonist
Less so with tramadol Cyclosporine
NOT tacrolimus (prokinetic properties)
-
Etiology
Enteric & Intrinsic mechanisms Loss of interstitial cells of Cajal (ICC)
pacemaker of the stomach - generate slow waves Loss of neuronal nitric oxide (nNOS)
DM neuropathy oxidative stress loss of ICC and nNOS
-
Etiology
Post Viral Sudden onset after prodrome illness Usually improves by about a year Autonomic neuropathy (CMV, EBV, VZV)
Slower resolution several years Worse prognosis
-
Etiology
Delayed gastric emptying longstanding DM1 Rapid gastric emptying early DM2
Vagal dysfunction due to DM or post surgical fundic accommodation gastric pressure rapid emptying of liquids

Diagnosis
Symptomatic Exclusion of other etiologies and obstruction
with endoscopy or radiological imaging Biochemical screen for hypothyroid & DM EGD Enterography or barium UGI
Delayed gastric empting rather thangastroparesis if asymptomatic
