Trial of pectin-enriched muffins in patients with severe dumping syndrome after gastric resection. Observations on symptoms and gastric emptying pattern.

Pectin is known to delay gastric emptying and alleviate dumping symptoms when ingested with hyperosmolar, glucose-containing meals. As the treatment of dumping syndrome includes frequent, small dry meals, the effect of pectin ingested in muffins was tested in five patients with severe, intractable dumping syndrome after gastric resection. Ingestion of 99mTc-DTPA-labelled muffins containing 5 g pectin did not alleviate dumping symptoms or delay gastric emptying compared with muffins without pectin. Pectin does not seem to be beneficial as a supplement in the conventional dietary management of post-gastrectomy dumping.
