Gastric emptying and bezoars

Endoscopic Gastric Food Retention in Relation to Scintigraphic Gastric Emptying Delays and Clinical Factors

“…Findings from this study show a close association of retained gastric food residue to delays in gastric emptying. This relationship has not always been observed in the [7,16]. However, these older studies had smaller sample sizes and used non-standardized methods to quantify emptying delays.…”

“…As many cases occur after gastric surgery with vagotomy suggests an important role for delayed gastric emptying, but attempts to attribute bezoar formation to impaired motor function have yielded conflicting results. Older studies reported normal gastric emptying in postsurgical patients with versus without bezoars, using non-standardized scintigraphic and nonscintigraphic methods (e.g., acetaminophen absorption) [7,16]. However, others noted delayed emptying in postsurgical and non-operated patients with bezoars using fluoroscopic and other techniques [9,11].…”

Giant Trichobezoar and Gastric Perforation in a Normal Healthy Woman

“…Delayed gastric emptying in patients with vagotomy is one of the hypotheses, 4 although some studies have found no difference in the gastric emptying time for solids in patients with and without surgery. 5 Our patient had no psychiatric history. She was a normal healthy woman with no past surgical or medical history.…”

“…Furthermore the advantage of CT scan over barium enema is to make diagnosis avoiding oral contrast material. 10,16,17 Oesophagogastroduodenoscopy is effective and useful to diagnose gastric bezoars.…”
