Final answer:
Stenosis at the gastrojejunostomy site following LRYGB is typically managed with balloon dilatation, which is generally the first line of treatment over other methods like conservative management, nasogastric tube insertion, or surgical excision. Option c.
Step-by-step explanation:
Stenosis of the gastrojejunostomy in Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is typically managed with balloon dilatation. This is a minimally invasive procedure that involves the insertion of a balloon through an endoscope, which is then inflated to widen the narrow area of the gastrojejunostomy.
The Roux-en-Y Gastric Bypass is one of the most effective medical treatments for obesity, which involves creating a small stomach pouch and attaching it directly to the jejunum, thus bypassing a significant portion of the stomach and duodenum. This alteration limits food intake and nutrient absorption. Conservative management, nasogastric tube insertion, or surgical excision are less commonly employed strategies for this condition and are not the first line of treatment.
