Hello, it usually takes about half a month to recover before the J tube can be taken out. Of course, the recovery of each patient is different, and it depends on the recovery of patients in all aspects. In particular, the replantation operation is very risky and requires an observation period of 1 week after operation. Therefore, half a month is a conservative estimate, and the specific situation needs to be treated specifically. I hope I can help you and wish you health!
