Use of bioabsorbable stent to manage a chronic anastomotic fistula following anterior rectal resection. After drainage of a perianastomotic abscess (not shown), CT (a) showed the persistence of perianastomotic inflammation (thin arrows) with gas bubbles (note the close similarity to Fig. 11b). Repeated CT (b–d) showed decreased perianastomotic inflammation (thin arrows) compared to a and confirmed correct placement of the bioabsorbable stent (thick arrows) which appears as a tubular structure with soft-tissue attenuation, best visible using MIP reconstructions (b).
