Amitabh Bachchan, who has been suffering stomach ailments from quite a long time, says he will be undergoing a minor surgery on February 11.

The 69-year-old actor will undergo a CT Scan tomorrow and the day after, he will be taken for the surgery.

'My stomach which has already been the bed of many complicated battles in the past, shall have to entertain this as well. It's a war zone, my body, and one which has been through a great deal and still does.

'A surgery that I shall be undergoing on the 11th morning and the surgery they say is not too complicated, but then all doctors say the same as you end up on the operating table, and before long the details and the subsequent anxieties begin to rise,' Bachchan posted on his blog.

Bachchan, who is currently shooting a cameo in Bhojpuri film Gangadevi with wife Jaya, blames his late night appearances behind the stomach problem.

'The doc who looks after me was furious at my late night appearances... but what does one do... it is this time of the night or the day when there is freedom and solitude to assuage what I must convey or not. But I do understand his concern and shall abide by it,' he added.
