BACKGROUND: The presence of synchronous benign and malignant colonic pathology may influence the magnitude of surgery for @entity14 . The aim of this prospective study was to quantitate the need for a more extensive surgical procedure because of synchronous pathology in @entity14 @entity1 . METHODS: Between 1984 and 1996, 235 consecutive @entity1 were treated for @entity14 . Preoperative survey of the colon in 228 @entity1 included colonoscopy (91%) and double contrast barium enema (35.7%). Seven @entity1 were excluded for incomplete preoperative survey because of perforating or obstructing @entity694 or @entity31 . RESULTS: One hundred four @entity1 (45.6%) had the following synchronous @entity1049 : benign @entity1127 (68 @entity1 , 29.8%), @entity66 (30, 13.1%), @entity31 (10, 4.4%), @entity420 (8, 3.5%), and @entity30 (3, 1.3%). Pathologic examination demonstrated three additional @entity420 for a total of 11 @entity1 (4.9%). Twenty-five (11%) required more extensive surgery than dictated by the primary @entity5 . Of these 25 @entity1 , 17 had a benign or @entity558 associated with their @entity189 and 8 had a @entity189 . Seventeen @entity1 underwent a sphincter-saving procedure. Of the remaining eight @entity1 requiring sphincter ablation, seven were needed because of a synchronous nonmalignant lesion, rather than because of the @entity5 . CONCLUSIONS: In our @entity1 population, the incidence of @entity14 was 45.6%. Synchronous @entity14 occurred in 4.9%. In 11%, the presence of @entity14 made the surgical procedure more extensive than that dictated by the primary @entity5 , and in 3%, the need for a sphincter ablating procedure was dictated by a synchronous nonmalignant lesion.
