    Notizen: Abstract A rare case of a patient who presented with a presacral tumor is described. The tumor, after complete resection, was shown to be a primary adenocarcinoma. After potential sources such as gastrointestinal, pancreas, or prostate were eliminated, the diagnosis of primary presacral adenocarcinoma was made. Possible origins of this unusual tumor are discussed.

    Notizen: Abstract A multicenter retrospective study was undertaken to assess the efficacy and safety of laparoscopy in colon and rectal surgery. To minimize potential bias in interpretation of the results, all data were registered with an independent observer, who did not participate in any of the surgical procedures. Sixty-six patients underwent a laparoscopic procedure. Operations performed included sigmoid colectomy (19), right hemicolectomy (15), low anterior resection (6), colectomy with ileal pouch-anal anastomosis (IPAA) (5), and abdominoperineal resection (APR) (3). The conversion rate from laparoscopic colectomy to celiotomy was 41 percent. Major morbidity and mortality were 24 percent and 0 percent, respectively. Length of stay, hospital costs, and lymph node harvest were compared between the sigmoid resection and right hemicolectomy subgroups. Data from traditional sigmoid colectomies and right hemicolectomies were obtained from the same institutions for comparison. Mean postoperative stay for laparoscopically completed sigmoid and right colectomies was significantly less than that for either the converted or the traditional groups (P 〈0.02). Total hospital cost for traditional right hemicolectomy was significantly less than that for the converted group (P 〈 0.05) but not the laparoscopic group. Laparoscopic sigmoid resection showed no significant total hospital cost difference among traditional, converted, and laparoscopic groups. Lymph node harvest in resections for carcinoma was comparable in all groups. These preliminary data suggest that laparoscopic colon and rectal surgery can be accomplished with acceptable morbidity and mortality when performed by trained surgeons. Length of stay is shorter, but there is no proven total hospital cost benefit. Appropriate registries will be necessary to adequately assess long-term outcome.

    Notizen: Abstract Anal endosonography is a new technique that is useful in the preoperative assessment of patients with anal fistulas. Endosonographic images are created by the reflection of sound waves from the interfaces between tissues of varying densities. In order to accentuate tissue interface layers at the level of the fistula tract, we introduced hydrogen peroxide into the fistula tract through the external opening during anal ultrasonography in two patients with recurrent anal fistula. Hydrogen peroxide injection resulted in hyperechoic imaging of the preinjection hypoechoic horseshoe fistula tract. Endosonographic findings were confirmed at the time of surgery in both patients. We conclude that hydrogen peroxide enhancement of the fistula tract is a simple, effective, and safe method of improving the accuracy of endoanal ultrasound assessment of recurrent anal fistula.

    Notizen: Abstract  Patients with constipation may have various pelvic complaints of difficult evacuation coexisting with infrequent evacuation and other abdominal complaints, and the overlapping of symptoms makes it difficult to select appropriate therapy based on clinical history and routine office examination alone. Cinedefecography is an objective method for examining patients who have complex subjective symptoms. This study assessed the value of cinedefecography for evaluating patients with constipation with multiple complaints. We divided 185 patients with constipation into two those with (group 1) or without (group 2) cinedefecographic evidence of difficult evacuation. These groups were compared relative to complaints, manometric results, cinedefecography findings, and the success of biofeedback treatment. Group 1 patients were further evaluated according to the type of abnormal findings: sigmoidocele, rectocele, intussusception, and perineal descent. We found no significant differences in patient complaints between the groups. However, there were more patients in group 2 with intussusception than in group 1; there were also significant differences between the groups in mean resting pressure, maximum resting pressure, and maximum squeeze pressure. In group 1 patients with rectocele complained more frequently of excessive straining, and those with intussusception complained more frequently of incomplete evacuation. Sensory threshold and maximal tolerable capacity were significantly higher in patients with intussusception. Rectocele was predominant in women, and biofeedback treatment was extremely advantageous (86%) for patients in group 1 with a rectocele in association with other pathology. Whether the intussusception or the descent causes decreased mean resting and mean and maximum squeeze pressures is unknown but is an additional and potentially important finding which needs further elucidation for it to have therapeutic significance.

    Beschreibung / Inhaltsverzeichnis: Résumé. But: La mortalité réelle, le coût et l'incapacité de travail en cas de traitement médical de la colite ulcéro-hémorragique sont rarement définis et encoure plus rarement comparés à des paramètres analogues associés au traitement chirurgical. Ceci nous a conduit à déterminer et comparer le traitement médical versus le traitement chirurgical chez des patients hospitalisés en raison d'une colite ulcéro-hémorragique. Matériel et méthodes: Les patients ont été comparés quant à l'âge, la durée et la sévérité de la maladie déterminée avec les indexes d'activité de Truelove et Witts, la colonoscopie, l'aspect histologique et le score APACHE. La morbidité, le coût et l'incapacité de travail déterminés chez 20 patients ayant requis au moins une hospitalisation, ont été comparés à ceux mesurés chez 20 patients traités par un procédé en trois temps opératoires. Les données démographiques, le nombre d'admissions hospitalières, la durée du séjour, le coût hospitalier total incluant le chirurgien consultant et l'anesthésiste, la morbidité de chaque traitement et l'incapacité de travail ont étéétablis. Des analyses statistiques ont été réalisées utilisant de test de Mann-Whitney ainsi que le test de Fisher. Le seuil de signification a été déterminéàP〈0.05. Résultats: L'âge moyen était de 53,6 ans dans le groupe traité de manière médicale et de 48,1% dans le group chirurgical (P = NS); la durée moyenne d'évolution de l'affection était de 10,5 et 9,5 ans (P = NS). La sévérité de la pancolite était présente dans les deux groupes. Le score d'APACHE calculéétait respectivement de 13 et 14 dans le groupe médical et le groupe chirurgical. Il n'y avait pas de différence significative entre le taux total d'admission hospitalière et le taux obtenu par séjour des patients dans chacun des deux groupes. Le taux moyen, en case de séjour hospitalier dans le groupe médical, s'établit à $ 28,477.– par patient alors que le taux en cas de traitement chirurgical à trois équipes est de $ 33,041.– en cas de proctocolectomie. La durée moyenne des séjours pré-hospitaliers avant l'intervention chirurgicale est de 5 mois dans le groupe chirurgical (P = NS). Les patients du groupe médical ont requis toutefois plus de transfusion (25%) en comparaison avec le groupe chirurgical (0%) (P〈0.01). Tous les patients du groupe chirurgical recevaient des stéroïdes manière permanente. Par ailleurs, alors que 65% des patients du groupe médical présentaient des complications à mettre en rapport avec la prise de stéroïdes, le taux de complications chirurgicales majeures est restéà 15% (P〈0.01). Conclusion: Le traitement médical est associéà un taux de complications significativement plus élevé que celui résultant de la seule chirurgie. En plus, une proctocolectomie avec restauration de la continuité a été réalisée sans coûts hospitaliers additionnels chez des patientes porteuses d'une colite ulcéreuse. La valeur d'un traitement médical prolongé dans ce groupe sélectionné de patients est discutable.
    Notizen: Abstract. Aim: The true morbidity, cost and disability of medical therapy for ulcerative colitis are seldom delineated and are even less frequently compared to analogous parameters associated with surgical therapy. Therefore, we sought to assess and contrast medical versus surgical therapy for patients hospitalized due to severe ulcerative colitis. Materials and methods: Patients were matched for age, duration and severity of disease based upon Truelove and Witts' activity index, colonoscopic and histologic appearance and APACHE (Acute Psychological and Chronic Health Evaluation) II scores. Morbidity, cost and disability of 20 medically treated patients who required at least one hospital admission were compared to 20 patients treated by a three stage restorative proctocolectomy. Demographic data, number of hospital admissions, length of stay, total hospital charges including consultant's, surgeon's, and anesthesiologist's fees, morbidity of each approach and disability were assessed. Statistical analysis was performed using Mann-Whitney and Fisher exact tests. Significance was considered as P〈0.05. Results: The mean age was 53.6 years in the medical group and 48.1 years in the surgical group (P = NS) and the average duration of disease was 10.5 years and 9.5 years, respectively (P = NS). The same severity of pancolitis was noted in both groups; APACHE scores of 13 and 14 in the medical and surgical groups, respectively, were noted. The total number of hospital admissions and total combined length of stay per patient in each group were not significant. Total mean hospital cost for the medical group was $ 28,477.00 per patient versus $ 33,041.00 for the three stage restorative proctocolectomy (P = NS). The mean duration of disability in the medical group was 6.4 months per patient versus 5.0 months in the surgical group (P = NS). However, patients in the medical group required more transfusions (25%) than did those in the surgical group (0%) (P〈0.05) and significant weight loss was more common in the medical group (45%) compared to the surgical group (5%) (P〈0.01). All patients in the surgical group were permanently weaned from steroids. Furthermore, while 65% of patients in the medical group had significant steroid-related complications, the major surgical complication rate was only 15% (P〈0.01). Conclusion: Medical treatment was associated with a significantly higher overall morbidity than surgical therapy. Additionally, a three stage restorative proctocolectomy was performed at no additional hospital cost or subsequent disability in patients with severe ulcerative colitis. The value of prolonged medical therapy in this select group of patients is questionable.

    Beschreibung / Inhaltsverzeichnis: Résumé. La vidéo-défécographie est une investigation dynamique qui peut conditionner le recours à une sanction chirurgicale chez des patients constipés. Une étude a été entreprise afin de déterminer la variabilité de l'évaluation des vidéo-défécographies inter et intraexaminateurs. Nous souhaitions soumettre l'interprétration de vidéo-défécographies à un groupe d'examinateurs de même niveau de formation en utilisant des directives et des standards communs. Afin de déterminer des différences entre examinateurs, quatre examinateurs ont vu 100 séquences de vidéo-défécographie réalisées chez des patients constipés; deux des quatre examinateurs ne connaissaient pas les données cliniques. Ils ont anoté la présence ou l'absence de sigmoïdocèle, de rectocèle, d'intussusception ou de prolapsus. Ils ont également dû se prononcer sur le fonc-tionnement adéquat ou inadéquat de la sangle pubo-rectale, de l'ouverture du canal anal, de l'angle ano-rectal, du degré d'évacuation du rectum. Deux semaines après l'évaluation initiale, des variations des décisions des observateurs ont été déterminées en soumettant à leur jugement les mêmes séquences de vidéo-défécographie dans un ordre différent et sans repère clinique. Les résultats de la concordance de jugement entre examinateurs quant aux sigmoïdocèles, rectocèles, intussusception, prolapsus du rectum, évacuation du rectum, ouverture du canal anal, contraction de la sangle pubo-rectale et ouverture de l'angle ano-rectal sont respectivement de 89,5%, 46,0%, 87,5%, 97,5%, 86,5%, 88,5%, 83,0% et 80,0%. Les variations de jugement intra-observateur sont respectivement 88,5%, 83,8%, 80,5%, 94,5%, 77,0%, 84,8%, 80,5%, 85,5%. Le fait de connaître l'histoire clinique des patients ne modifie pas de manière significative le jugement. En résumé, la vidéo-défécographie permet une concordance des opinions dans 83,3% des cas et est, par conséquent, un moyen utile d'évaluation des patients constipés.
    Notizen: Abstract. Video defecography is a dynamic investigation which can influence surgical decision making in constipated patients. A study was therefore undertaken to assess the inter and intraobserver variability in video defecography. Specifically, we sought to assess the interpretation of video defecographies by a group of observers with the same training, guidelines and standards. To determine interobserver variation, four independent observers, two blinded to the patient's history, reviewed 100 randomly sequenced video defecographies performed in constipated patients. The presence or absence of sigmoidocele, rectocele, intussusception or prolapse was noted. Adequate or improper function of the puborectalis, anal canal opening, anorectal angle (ARA) and grade of emptying of the rectum were also assessed. Two weeks after the initial assessment, intraobserver variation was determined by a repeat blinded review of unlabelled randomly sequenced studies. The results of interobserver accuracy for sigmoidoceles, rectoceles, intussusception, rectal prolapse, rectal emptying, opening of the anal canal, puborectalis contraction and straightening of the ARA and rectal emptying were 89.5%, 46.0%, 87.5%, 97.5%, 86.5%, 88.5%, 83.0%, and 80.0%, respectively. The intraobserver variations were 88.5%, 83.8%, 80.5%, 94.5%, 77.0%, 84.8%, 80.5% and 85.5%, respectively. Prior knowledge of the patient's history did not significantly influence the outcome. In summery, video defecography has an overall accuracy of 83.3% and as such is a valid tool in assessing constipated patients.

    Notizen: Abstract  This study compared the outcome factors of morbidity and the length of disability in older and younger patients following laparoscopic colorectal surgery. All patients undergoing laparoscopic segmental resection during the study period were included. Morbidity was determined by reviewing the medical records, and disability by a patient-administered questionnaire. The series was divided into two age cohorts (≤64 and ≥65 years), which did not differ significantly in gender or type of procedure. Between these two groups we found no significant differences in mean duration of ileus (3.3 days in both groups), the mean length of hospitalization (5.7 vs. 6.3 days, respectively), morbidity rate (18% vs. 21%), or time until returning to partial activity (1.6 vs. 1.6 weeks) or to full activity (3 vs. 2 weeks). Our findings demonstrate that neither the morbidity rate nor the disability period after laparoscopic techniques differ between elderly and younger patients. We therefore endorse the use of laparoscopy regardless of patient age.
