Final answer:
In abdominal procedures for obese patients, additional bariatric surgery, such as the Roux-En-Y procedure, may be performed if new pathologies like gallstones are identified.
Step-by-step explanation:
During abdominal procedures on patients who are obese, an additional procedure that might be performed due to newly identified pathology is bariatric surgery. This surgery modifies the stomach and sometimes the small intestine to help reduce food intake and nutrient absorption, thus aiding in weight loss. The most common form of bariatric surgery is the Roux-En-Y procedure, where a small pouch is created in the stomach and connected directly to the jejunum, bypassing the stomach and duodenum. When abdominal procedures like laparoscopy are conducted, they may reveal issues such as gallstones or other conditions that could necessitate immediate surgical treatment, such as a cholecystectomy.
