usually staplers fall off their own around 14th day of the procedure.sometimes, some of them may remain which usully fall off within another 1 wk. I would suggest you to wait for another week and if staples persist even after that you may visit your operating surgeon fo manual removal of staplers. the procedure is usualy painless/ minimally painful.
Next Steps
wait for 1 more week. these should fall off by their own within that period. if not visit operating surgeon.
