Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does incidental parathyroidectomy during thyroid surgery cause transient symptomatic hypocalcemia?
Answer: Unintended parathyroidectomy, although not uncommon, is not associated with symptomatic postoperative hypocalcemia. Modified radical neck dissection may increase the risk of incidental parathyroidectomy. Most of the glands removed were intrathyroidal, so changes in surgical technique are unlikely to markedly reduce this risk.
no

Question: Is previous laparotomy a contraindication to laparoscopy-assisted gastrectomy for early gastric cancer?
Answer: There was no difference in outcome following LAG between the PSURG and NSURG groups in the present study. The PSURG patient is not contraindicated for LAG assuming careful attention is given for all operative procedures, including port insertion and dissection of intra-abdominal adhesions.
no

Question: Does preoperative 6-minute walk test add prognostic information to Euroscore in patients undergoing aortic valve replacement?
Answer: The 6MWT is safe and feasible to carry out in patients with severe aortic stenosis before AVR, and provides potentially important functional and prognostic information to clinical assessment and the Euroscore risk score.

yes
