    Notes: Abstract  This retrospective study determined whether a hand-sewn or stapled anastomosis leads to a greater recurrence rate in patients undergoing ileocecal resection for terminal ileal Crohn’s disease. The effects of oral contraceptive use, smoking, and age at onset of disease were also examined. Ninety-two patients with Crohn’s disease of the terminal ileum whose first operation was an ileocecal resection (terminal ileum and right colon up to but not including the hepatic flexure) were studied for symptomatic and operative recurrence. The symptomatic recurrence rates were 15% at 1 year, 31% at 2 years, and 45% at 3 years. The operative recurrence rates were 6% at 1 year, 14% at 2 years, and 22% at 3 years. The type of anastomosis, whether hand-sewn or stapled, did not affect the rates of symptomatic (P=0.3) or operative (P=0.6) recurrence. After the initial resection smoking affected both symptomatic (P=0.03, risk ratio=2.380) and operative (P=0.041, risk ratio=3.13) recurrence, but there was no effect of age at onset of disease or use of the birth control pill.

    Notes: Abstract Between December 1981 and March, 1987, 188 ileal reservoir and ileoanal anastomosis procedures were performed at the University of Toronto. Anal anastomotic complications occurred in 24 (12.8%) patients. There were 19 patients who developed a leak as a result of non-healing of the ileoanal anastomosis (group 1). Late fistulae occurred in 5 patients (group 2). Various treatments were employed. In group 1, 2 of 15 (13%) patients treated with drainage and antibiotics, 3 of 7 (43%) in whom the anastomosis was resutured, and 5 of 7 (71%) in whom repair was performed by advancing the ileal outlet and resuturing the anastomosis, healed their anastomosis. One patient was treated successfully by performing a fistulotomy. Treatment was unsuccessful in one patient in whom the ileal reservoir and ileoanal anastomosis were revised and re-anastomosed. One patient (50%) in group 2 was treated successfully by advancing the ileal outlet and resuturing the anastomosis. Complete healing of the anastomosis was achieved in 12 patients (50%), although 3 patients subsequently required excision of the reservoir because of inability to evacuate spontaneously (1), incontinence (1), or psychological reasons (1). All nine (38%) patients who were functioning with their ileal reservoir were continent. One patient intubated the reservoir. The rate of urgency and soiling, and the number of bowel movements per 24 hours did not differ significantly from those of patients without these anastomotic complications. Our results suggest that early diagnosis and repair of ileoanal anastomotic dehiscence by advancement of the ileal outlet and resuturing of the ileoanal anastomosis results in improved reservoir salvage and satisfactory functional results.

    Description / Table of Contents: Résumé Bien que l'étude scintigraphique de la vidange des poches pelviennes ait été utilisée pour évaluer la fonction du néorectum chez les patients qui ont subi une colectomie ou une proctectomie muqueuse et une anastomose iléo-anale avec réservoir, les études précédentes n'ont pas étudié la valeur de ce test pour mesurer le volume de la poche et sa vidange. Cette étude a donc été entreprise pour déterminer: (1) la valeur de la méthode chez les patients avec un résultat fonctionnel stable: (2) si une vidange fractionnée est corrélée avec le volume de la poche. 10 patients ayant un résultat fonctionnel stable ont eu à deux reprises à une semaine d'intervalle une scintigraphie au technecium 99. Le volume moyen des selles artifielles instillées était de 338±104 CC. La différence moyenne de volume instillé entre le premier et le deuxième scan était de 78±26 CC et la différence moyenne absolue du pourcentage évacué était de 12±9%. Cette différence entre les deux examens n'était pas statistiquement significative (p〉0.05). Il n'y avait pas de corrélation significative entre le volume des selles artificielles instillées dans la poche pelvienne et la fraction spontanément évacuée (r=-0.1). Le résultat suggère que la scintigraphie au technécium 99 de la vidange d'une poche pelvienne est valable chez les patients qui ont un résultat fonctionnel stable. La quantité de matières évacuée est indépendante du volume de la poche.
    Notes: Abstract Although scintigraphic pelvic pouch emptying scans have been used to evaluate neorectal function in patients who have undergone colectomy, mucosal proctectomy, and ileoanal pouch anastomosis, previous reports have not documented the reliability of this test in measuring pouch volume and emptying. Thus, this study was undertaken to determine: (1) the reliability of this test in patients with stable functional results and, (2) whether the emptying fraction correlates with the volume of the pouch. Ten patients who had stable functional results had 99m Tc-sulphur colloid pouch emptying scans performed on two occasions, one week apart. The average volume of artificial stool that was instilled was 338±104 cc. The mean difference in the volume instilled between the initial and repeat scans was 78±26 cc and the mean absolute difference in the percentage evacuated was 12±9 percent. These inter-test differences were not statistically significant (p〉0.05). There was no correlation between the volume of artificial stool instilled into the pelvic pouch and the fraction spontaneously emptied (r=-0.1). Our results suggest that the 99m Tc-sulphur colloid pelvic pouch emptying scan is reliable in patients with stable functional results. Pouch emptying fraction is independent of pouch volume.

    Notes: Abstract. A rare case of chronic intussusception is reported. Radiological investigation including ultrasound, CT and barium enema provided the correct diagnosis. Ultrasound revealed a solid mass near the transverse colon in the right lower abdomen. CT demonstrated the real nature of the solid mass as being the classical ’coiled spring' of intussusception. The barium enema was unsuccessful as an attempt at hydrostatic reduction, but confirmed the diagnosis by a ’crescent-shaped' filling defect in the ascending colon. The patient was discharged after an uneventful surgery and recovery. No organic lesion that precipitated the chronic intussusception was discovered at operation. Radiological findings, the typical clinical picture and adequate treatment are discussed.
