Figure 1 Evaluation before endoscopic retrograde cholangiopancreatography. A: Magnetic resonance imaging revealed a right-sided stomach and midline liver placement; B: Computed tomography revealed a right-sided pancreas and left-sided inferior vena cava; C: Magnetic resonance cholangiopancreatography, indicated a midline liver placement and a stone measuring 0.6 cm in the common bile duct; D: Gastroscopy revealed inverted greater and lesser curvatures (view at the cardia, white arrow: Direction of the antrum).

Figure 2 Endoscopic retrograde cholangiopancreatography procedure. A: Papillary oriented at 11 o’clock; B: Accessing the common bile duct (CBD) with an endoscopic retrograde cholangiopancreatography cannula; C: Cholangiography revealed mild CBD dilation with the impacted stone measuring 0.6 cm; D: Endoscopic papillary balloon dilation (6 mm, maximum pressure 35 standard atmospheric pressure); E: Basket used to remove the stone; F: Postoperative cholangiography showed no residual stones and an inverted stomach shape.
