The pathophysiology of constipation after rectopexy remains unclear: acquired anorectal dysfunction or preoperative colonic state are, by turns, the supposed culprit. The aim of this prospective study was to characterize the colorectal motility abnormalities encountered after such a surgical procedure. Twelve patients (10 females, 2 males, aged 50.5±5.2 years) complaining of severe constipation or its worsening after orr rectopexy (OR) for rectal prolapse were studied. Each underwent detailed interrogation as to their symptoms, left colonic manometry (basal and postprandial motor indexes and their caudad gradients in the sigmoid), anorectal manometry, evacuation proctography, and colonic transit time with radiopaque markers. Results were compared to those obtained in two control groups: 10 healthy volunteers (HV) and 12 patients complaining of a rectal prolapse (RP) observed consecutively during the same period of evaluation (June 90 to December 91). Before surgery, the OR and RP groups were similar with respect to mean age, sex ratio, weekly stool frequency, subjective dyschezia and manual anal supplies, constipation symptoms, and anal incontinence. OR patients differed significantly from the RP group in having a lower weekly stool frequency (2.5±2.2 vs 5.2±3.7,P

The aim of this study was to determine whether the sensitivity of indium-111 (111In) scanning in the assessment of the activity and extent of Crohn's disease correlates with the severity of intestinal lesions as measured by the newly validated Crohn's disease endoscopic index of severity (CDEIS). Nineteen patients with active (CDAI>200) colonic (N=11) or ileocolonic (N=8) Crohn's disease were assessed by colonoscopy and indium scanning. The intestine was divided into five segments in both studies (rectum, sigmoid and left colon, transverse colon, right colon, and ileum). Seventy of the 86 intestinal segments seen at colonoscopy presented macroscopic lesions of Crohn's disease. On third-hour scintigrams111In uptake was observed in 52 segments, 51 of which were found to be abnormal at colonoscopy. Predictive positive and negative values of scanning with respect to disease extent assessment were equal to 98% and 44%, respectively. Complete agreement between endoscopic and scintigraphic findings was observed in only six of the 19 patients (32%). Segmental endoscopic indexes of severity (SEIS) were significantly (P
