his 80 year old lady had presented with a common bile duct stone (bit unusual in her age group if our past experience was anything to go by). The ampulla was quite swollen (A :white arrow). Contrast injection showed a stone in the upper CBD (B: white arrow). We did a large papillotomy (C: white arrow), keeping in mind the size of the stone. The first attempt at stone extraction was made using a balloon which was maneuvered
across the stone (D: white arrow & E: white arrow shows the balloon inflated behind the stone, marked by the red arrow). The balloon kept slipping past the stone (F: white arrow shows the balloon which has slipped below the stone, marked by the red arrow). We went for the basket next (G: white arrow points to the open basket next to the stone, indicated by red arrow). This was successful and the stone was finally extracted (H1 & H2). Quite large and almost a perfect cylinder (I). Shotgun slugs, anyone?
