Pouchoscopy findings before and after ganciclovir therapy. A and B show endoscopic photographs of the pouch one day after admission to our hospital before treatment with ganciclovir; note the size of the biopsy tweezers in the lower left corner of A. C shows a comparable view into the pouch 25 days after the end of the first hospital stay and after treatment with ganciclovir and valganciclovir. At that time point, the mucosa was smooth and shiny within the whole pouch except for a single small ulceration (about 3×7mm) in the pouch corpus; D shows the view into the pouch on day 6 of the second admission to our hospital. The ulceration, marked with an arrow, is clearly healing.
