stoma
Pronunciation: STOH-mah
The surgically created opening or connection between organs, particularly the gastrojejunal anastomosis in bypass surgery.
Full Definition
In bariatric surgery, a stoma refers to the surgical connection between the gastric pouch and small intestine, most commonly the gastrojejunal anastomosis in Roux-en-Y gastric bypass procedures. The stoma diameter is critical for optimal restriction and weight loss, typically measuring 10-15mm. Stoma complications include stenosis (narrowing), which causes vomiting and food intolerance, or dilation, which reduces restriction and may lead to weight regain. Endoscopic evaluation can assess stoma patency and diameter, with therapeutic interventions available for both stenotic and dilated stomas.
Usage
Usage note: Context determines whether referring to general surgical opening or specific bariatric anastomosis.
