M. Vieth et al., ADENOCARCINOMA IN AN ILEAL POUCH AFTER PRIOR PROCTOCOLECTOMY FOR CARCINOMA IN A PATIENT WITH ULCERATIVE PANCOLITIS, Virchows Archiv, 433(3), 1998, pp. 281-284
We report the first known case of pouch carcinoma in a 35-year-old fem
ale patient following proctocolectomy for adenocarcinoma in ulcerative
pancolitis with backwash ileitis. Pouch cancer was diagnosed 2 years
after the pelvic pouch procedure, illustrating that there might be a r
isk of pouch cancer in such patients. Adenocarcinoma arising in an ile
oanal reservoir is rare. Two other cases have been reported: both pati
ents concerned were believed to have developed cancer in small areas o
f residual remaining rectal mucosa.
