    Notes: Abstract Primary aortoenteric fistula is rare. The most common cause is atherosclerosis, followed by infection and carcinoma of the head of the pancreas. A case of spontaneous aortojejunal fistula due to recurrent colorectal cancer is reported.

    Notes: Abstract PURPOSE: This study examined the effect of blood transfusion on the prognosis of patients undergoing surgery for colorectal cancer. METHODS: Potentially curative resections for colorectal cancer were performed in 266 patients who were followed prospectively, with a minimum follow-up of 41 months. They were divided into transfused (n=121) and nontransfused (n=145) groups according to their perioperative blood transfusion requirements. RESULTS: There were significantly more rectal tumors (χ2=9.5, df=1, P=0.002) and fixed tumors (χ 2 =4.5, df=1,P=0.03) in the transfused group. There was no statistically significant difference between the two groups with regard to recurrence-free survival (χ 2 =1.1, df=1,P=0.3) and overall survival (χ 2 =2.8, df=1,P=0.09). CONCLUSION: In this study we have found no statistically significant effect of perioperative blood transfusion on the prognosis of colorectal cancer patients.

    Notes: Abstract A full first-degree family history was taken from 161 patients with colorectal cancer (Group 1) and from a group of 203 subjects previously investigated and found to have no colorectal neoplasia (Group 2). Twenty-six (16%) of patients in Group 1 compared with 23 (11%) in Group 2 had at least 1 first-degree relative with colorectal cancer (p=0.23). Contact of first-degree relatives was possible in 123 patients in Group 1. Of these, 4 were members of ‘cancer families’ with 26 available first-degree relatives. The remaining 119 patients had 341 contactable first-degree relatives. They were approached by post and offered faecal occult blood (FOB) screening. One hundred and sixty-two (47%) completed FOB tests of which 12 (8%) were positive. Investigation of these individuals detected 4 adenomas. In the subgroup of 20 patients with 1 or 2 first-degree relatives with colorectal cancer, there were 78 potential relatives of whom 71 were contacted. Thirty-two (45%) FOB tests yielded 1 positive found to have an adenoma. A control group of 332 individuals was selected randomly from general practitioners' lists and offered FOB testing. One hundred and fifty-five (47%) complied of whom 7 (4.5%) were positive. Investigation yielded 1 adenoma. Thirteen of the 26 relatives of the 4 ‘cancer family’ patients were investigated by endoscopy and 2 (15%) had large polyps detected. Although there may be an increased risk of colorectal neoplasia in first-degree relatives of patients with sporadic colorectal cancer, this risk is not sufficiently high to justify separate screening.

    Description / Table of Contents: Résumé. La fistule anale est une pathologie commune qui nécessite un diagnostic précis du trajet fistuleux car tout inadéquation de l'évaluation et du traitement chirurgical peut conduire à des interventions multiples inutiles et peut rendre un patient incontinent. Plusieurs études ont suggéré que la résonance magnétique (MRI) permet d'identifier avec précision un trajet fistuleux en relation avec le complexe sphinctérien. Le but de cette étude est d'investiguer l'utilité d'une MRI de routine pré-opératoire, examen totalement non invasif chez des patients suspects d'être atteints d'une fistule anale. Chaque scanner a étéévaluéà deux occasions par un consultant radiologue afin de déterminer si l'opinion du radiologue a été modifiée et/ou si elle devient plus précise par l'expérience acquise. L'évaluation chirurgicale a été réalisée sous anesthésie générale par un chirurgien sans qu'il ne connaisse le résultat de la MRI. Les résultats de l'évaluation chirurgicale et du scanner MRI ont été comparés et l'intervention chirurgicale complétée. Trente-trois patients avec un diagnostic clinique de fistule anale ont été traités et dans 27 cas la fistule anale a été confirmée par la suite. La MRI met en évidence le tractus fistuleux dans 42% des cas de manière correcte à l'évaluation initiale et dans 50% des cas à la fin de l'étude, l'ouverture interne dans 63 et 74% des cas, l'ouverture externe dans 33 et 46% des cas et les abcès dans 50 et 33% des cas. Ces données suggèrent l'existence d'une courbe d'apprentissage pour le radiologue qui investigue des fistules anales à l'aide de la MRI, ceci est probablement dû au fait que la pathologie des fistules anales et l'anatomie du complexe sphinctérien sont des données relativement nouvelles pour les radiologues. L'examen de routine à l'aide de la MRI de patients porteurs de fistule anale n'est pas nécessaire mais peut jouer un rôle pour l'évaluation de fistules complexes ou difficiles.
    Notes: Abstract. Fistula-in-ano is a common condition in which accurate diagnosis of the fistula track is essential as inadequate assessment and surgical treatment may lead to multiple unnecessary operations and may also render the patient incontinent. Several studies have suggested that Magnetic Resonance Imaging (MRI) can accurately identify the fistula track in relation to the sphincter complex. The aim of this study was to investigate the value of the routine use of completely non-invasive pre-operative MRI in patients with suspected fistula-in-ano. Each scan was reported by a consultant radiologist on two occasions to determine whether the radiologist's opinion had changed and/or become more accurate with further experience. Surgical assessment of the fistula was performed under general anaesthesia by one surgeon without knowledge of the result of the MRI scan. The results of the surgical assessment and the MRI scan were compared and the surgical procedure completed. Thirty three patients with a clinical diagnosis of fistula-in-ano were treated and 27 subsequently confirmed to have a fistula. MRI detected 42% of tracks, identified correctly on initial assessment which increased to 50% at the end of the study, 63% and 74% of internal openings, 33% and 46% of external openings and 50% and 33% of abscesses. These data suggest that there is a learning curve for radiologists undertaking MRI scanning for fistula in ano, this is probably because the pathology of fistula in ano and anatomy of the anal sphincter complex are relatively new to radiologists. Routine MRI scanning of patients with fistula-in-ano is not necessary but there may be a role for MRI in assessing complex or difficult fistulae.
