Input: Question: Do obese patients have similar short-term outcomes to non-obese in laparoscopic colorectal surgery?
Answer: Obesity (BMI > 25) does not lead to worse short-term outcomes in laparoscopic colorectal surgery and therefore such patients should not be precluded from laparoscopic surgery.
Output:
yes
