Definition: 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.
Input: Question: Is initial resection of potentially viable tissue optimal treatment for grades II-IV pancreatic injuries?
Answer: Grade II pancreatic injuries do not require routine surgical exploration in children. Grade III and IV injuries in this series were treated with expeditious drainage of the pancreatic bed and did not require routine pancreatectomy or endoscopic stent [corrected] placement as some have recommended. Early drainage shortens hospital stay, and outcomes from this therapy are excellent. Pancreatic resection of exocrine defunctionalized segments of pancreas may be performed safely electively after acute injury if necessary, but anecdotal information from this series indicates that too may not be necessary. Grade V injuries often are accompanied by multiple other organ injuries and are associated with a significant mortality rate. A multi-institutional investigation is warranted to reassess optimal therapy for pancreatic injury in children.
Output:
no
