Abstract
Aims and background To assess the long-term histological, apoptotic and proliferating alterations of the intestinal mucosa of ileal conduits and orthotopic neobladders. Methods Fifty patients (46 males, 4 females), aged 52–78 years, who underwent urinary diversion with either ileal orthotopic neobladder (group ON, 20 patients) or conduit (group IC, 30 patients) from 2001 to 2005, were included in this prospective study Ileal samples were collected during surgery (controls) and by random mucosal biopsies 6, 12, 24, 36 and 48 months later. Histological (villi height, crypt depth, eosinophil cell count), proliferation (Ki67 immunochemistry), and apoptotic (Bcl-2 immunochemistry TUNEL) parameters were assessed. Results During the 4-year follow-up, we recorded progressive villi area, height and crypt depth reduction, mucosa flattening, and inflammatory and eosinophilic infiltration. Villi height: crypt depth ratio showed a statistically significant difference ( P <0.05) between the two groups from the 6th month. Dysplasia, metaplasia, and neoplasia were not observed. Bcl-2 values showed a progressive increase until 24 months in group ON and 12 months in group IC, followed by a decline thereafter. Ki-67 values showed a progressive increase after 6 months in group ON and an increase until 24 months followed by a decline thereafter in group IC. TUNEL showed two peaks, at 24 and 48 months. Conclusions Histological adaptation was revealed in both groups, with statistically significant differences in favor of orthotopic substitution. Proliferative and apoptotic pathways are implicated as demonstrated by relevant modifications of Bcl-2, Ki-67 and TUNEL, in accord with the histological adaptation.

Abstract
Augmentation cystoplasty operations using segments of gastrointestinal tract are often necessary in neurogenic low-compliance bladders. Patients are usually rehabilitated with an increase in storage volume and normalization of the reduced compliance. However, gut mucosa-related early and late complications are not very uncommon. Malignancy, although rare, is known to occur after enterocystoplasty, but only one such case has been reported for gastrocystoplasty, a single patient who developed urothelial carcinoma. We describe what we believe to be the first case of signet ring cell carcinoma developing after gastrocystoplasty.
