This 35 year old lady had undergone cholecystectomy at a private facility last month which was complicated by a biliary leak. She was reopened and a T-tube was placed. A post procedure T-tube cholangiogram showed a calculus in the CBD (A: Red arrow). The T-tube was then removed and she was referred to our centre. An MRCP was done which confirmed the cholangiogram findings of a CBD stone (B: White arrow). Contrast injection on ERCP showed a vague negative shadow in the upper CBD (C: Blue arrow indicates the concerned area while white arrow shows an inflated biliary balloon at the distal CBD). Sphinchteroplasty was planned there wasn't margin for a full blooded sphincterotomy and a 12-15mm TTS balloon rated at 3-8 ATM (D) was used to dilate the ampulla (E: Black arrow shows the inflated balloon). The patient experienced pain despite high dose IV analgesics so we restricted ourselves to 12mm dilatation for 10 seconds (F: Black arrow shows the post sphincteroplasty ampulla). At this point we were skeptical as to whether the stone would be retrieved. Nevertheless a sweep was made and successful stone extraction was done (G1 & G2: Black arrows show the stone being retrieved). An occlusion cholangiogram with an inflated ballon at the ampulla (H: White arrow) showed a clear CBD.
