Clip-stone and T clip-sinus post laparoscopic biliary surgery: Two case reports and review of the literature

Figure 1  Computed tomography coronal view shows a strip of high-density shadow in the common bile duct.

Figure 2 Magnetic resonance cholangiopancreatography showing a low-signal foreign body in the common bile duct (the external shape is similar to a Hem-o-lok clip). A-C: High-density shadow in the common bile duct.

Figure 3  A high-density strip shadow can be seen near the T-tube sinus.

Figure 4  High-density shadows can be seen.

Figure 5  Endoscopic retrograde cholangiopancreatography shows a stone in the common bile duct centered on the Hem-o-lok clip.

Figure 6  Stone fragments and two large Hem-o-lok clips were removed using a stone balloon.
