Oddi sphincter preserved cholangioplasty with hepatico-subcutaneous stoma for hepatolithiasis

Figure 1 Connecting the opened neighboring bile ducts to form a “hepatobiliary basin” (A); Obtaining a 12-15 cm free jejunum segment with a vascular pedicle (B); Performing a side-to-end anastomosis between the distal end of the free jejunum segment and the “hepatobiliary basin” (C); and Embedment in the skin after the closure of the free jejunum segment at its proximal end (D).

Figure 2 Oddi sphincter preserved cholangioplasty with hepatico-subcutaneous stoma in which the free jejunum segment served as the subcutaneous stoma (A) or in which the gallbladder served as the subcutaneous stoma (B). AW: Abdominal wall.
