Task: Answer Verification
Input (English): Question: Is gynecologic laparoscopic surgery associated with an increase of serotonin metabolites excretion?
Answer: The mechanism leading to the high incidence of postoperative nausea and vomiting after gynecologic laparoscopic surgery is unknown. The excretion of the serotonin metabolite 5-hydroxyindoacetic acid did not increase during the creation of the pneumoperitoneum and the first 9 h postoperatively. Increase of serotonin secretion from the gut may not explain postoperative nausea and vomiting associated with this surgery.
Output (English): no
