Cholecystectomy and clinical presentations of gastroparesis.
Parkman, Henry P, Yates, Katherine, Hasler, William L et al. · Digestive diseases and sciences · 2013 · DOI
Quick Summary
This study looked at 391 patients with gastroparesis (a condition where the stomach empties food slowly) to see if those who had their gallbladder removed had different symptoms than those who hadn't. They found that patients who had gallbladder surgery experienced more severe upper abdominal pain and retching, but less constipation. Interestingly, patients with prior gallbladder removal also had more other health conditions, including chronic fatigue syndrome and fibromyalgia.
Why It Matters
Many ME/CFS patients report gastrointestinal symptoms including gastroparesis, and this study reveals that prior gallbladder surgery is associated with distinct symptom patterns and higher rates of comorbid conditions like ME/CFS itself. Understanding these associations may help clinicians better recognize and manage gastroparesis in ME/CFS populations and inform decisions about surgical interventions in patients with multiple concurrent conditions.
Observed Findings
36% (142/391) of gastroparesis patients had prior cholecystectomy; rates varied by diabetic status (46% T2DM, 24% T1DM, 38% idiopathic gastroparesis)
Postcholecystectomy patients had significantly higher rates of chronic fatigue syndrome, fibromyalgia, depression, and anxiety compared to those without surgery
Patients with prior cholecystectomy reported more severe upper abdominal pain (OR=1.21) and retching (OR=1.19), but less severe constipation (OR=0.84)
Postcholecystectomy gastroparesis was associated with insidious symptom onset (OR=2.06) and greater comorbidity burden (OR=1.26 per additional condition)
Less severe gastric retention was independently associated with prior cholecystectomy (p=0.03)
Inferred Conclusions
Prior cholecystectomy is independently associated with a distinct symptom profile in gastroparesis characterized by increased upper abdominal pain and retching but reduced constipation severity
Postcholecystectomy gastroparesis patients experience higher comorbidity burden including notably elevated rates of chronic fatigue syndrome and fibromyalgia
The higher prevalence of comorbid conditions in postcholecystectomy patients suggests shared underlying pathophysiological mechanisms or that systemic illness predisposes to multiple surgical and functional conditions
Remaining Questions
Does prior cholecystectomy causally alter gastroparesis presentation, or do patients with specific GI pathophysiology have increased risk of both conditions?
What This Study Does Not Prove
This study does not prove that cholecystectomy causes gastroparesis or specific symptom presentations—only that they are associated. The cross-sectional design cannot determine causality or directionality: patients may have had surgery because of pre-existing GI dysfunction, or surgery may have altered symptom expression. The high rate of ME/CFS in the postcholecystectomy group raises questions about whether shared underlying pathophysiology predisposes to both conditions rather than one causing the other.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →

Why is chronic fatigue syndrome so overrepresented in the postcholecystectomy group—is there a shared biological mechanism or selective surgical referral pattern?
Do patients with prior cholecystectomy and gastroparesis respond differently to medical or surgical treatments compared to those without prior surgery?
What is the temporal relationship between gallbladder removal and gastroparesis symptom onset in these patients?
