<s>[INST] My 16 yr old son had an emergency appendectomy 2 weeks ago and last night had vomiting, diarrhoea and severe abdominal pains and he was admitted to hospital again . A surgeon has said he may have sticky bowels, a common after effect of an appendectomy, what does he mean and could this be a recurrent problem?Ad [/INST] Hello! Thank you for the query. Any complication post appendectomy is rare. If appendix is not perforated, a surgery is quite safe, quick, simple and do not cause any complication. If any complication appears, its wound infection at first. Your sons symptoms indicate partial bowels' obstruction. This is very rare complication of this procedure. Such obstruction can be caused by adhesions or twisted intestine. It can recur. In case of his symptoms he should have abdominal CT done to see if there is no fluid collection in the appendectomy area which can be also a reason of such symptoms. Hope this will help. </s>
