Dear ...! Many thanks for the mail. I have gone through your mail and noted its contents. Blood in sputum a week after laparoscopic cholecystectomy can be many things. Firstly a chest x-ray might have been done just before cholecystectomy and it would have shown anything ominous or unusual to be a cause of hemoptysis (blood in sputum). Secondly the endotracheal tube that might have been introduced through your throat for general anaesthesia could have caused some irritation and caused a little bleed. bronchitis in itself can cause a small amount of hemoptysis. Surgery in general is very unlikely to have caused you this symptom. Either way it is not ideal to ignore any blood in sputum You should be seen by a chest physician at the earliest to make sure everything is alright. Regards
