    Notes: Abstract Esophageal manometry allows to quantify intraluminal pressure changes as the basis of normal or abnormal esophageal motility. It is a complementary diagnostic procedure which should only be performed after endoscopic and fluoroscopic examinations and may be helpful in the detection of various motility disorders like diffuse esophageal spasm, nutcracker esophagus and vigorous achalasia. Manometry is recommendable for therapy control after medical and surgical therapy, and mandatory prior to surgical reflux therapy.

    Notes: Abstract Surgery for the treatment of Zenker's diverticulum was performed at our institution in a total of 43 patients over 6½ years. Cervical myotomy with diverticulectomy was performed in 32 of the patients and myotomy alone in 11. Mortality totaled 0%, with a reversible lesion of the recurrent nerve occurring in 7%. In 60% of the cases investigated preoperatively (N=40), motility disorders of the upper esophageal sphincter (UES) could be demonstrated using manometry as well as with cineradiography in 92% of the patients. Follow-up studies in 39 of the cases 25 months (mean) postprocedure indicated 82% of the patients to be symptom-free, with the remaining 18% demonstrating a marked improvement. Postoperative manometry as well as cineradiography carried out in 12 patients revealed the presence of UES motility dyscoordination in 8% and 25%, respectively. There were, however, no signs of recurrence of the diverticulum. The high number of patients in our study group demonstrating motility disorders of the UES emphasizes the need for cervical myotomy as part of the surgical therapy for Zenker's diverticulum.

    Notes: Abstract Surgical treatment is either the therapy of choice or a facultative procedure in various types of esophageal motility disorders. In achalasia, cardiomyotomy, frequently combined with fundoplasty, achieves good or excellent results in 〉80% of cases, and is, therefore, advised in cases when pneumostatic dilatation fails. Diverticulectomy and myotomy of the upper or lower esophageal sphincter are proven procedures to treat cervical and epiphrenic diverticula, leading to good/excellent results or at least an improvement in more than 95%. If, exceptionally, parabronchial diverticula require therapy, they should be excised transthoracically. Cervical myotomy is indicated in cases of cervical achalasia, when sufficient pharyngeal propulsion is preserved. In systemic diseases like scleroderma reflux induced complications may require surgical intervention in medically intractable cases. In these rather few cases, subtotal gastrectomy with a Roux-en-Y anastomosis is advised. In patients suffering from diffuse esophageal spasm or symptomatic “nutcracker” esophagus, extended esophageal myotomy can relieve symptoms. If a clear diagnosis is provided, about 75% of patients will have an improvement of symptoms.

    Notes: Abstract Barrett's esophagus (i.e. columnar epithelial metaplasia in the distal esophagus) is an acquired condition that in most patients results from chronic gastroesophageal reflux. It is a disorder of the white male in the Western world with a prevalence of about 1/400 population. Due to the decreased sensitivity of the columnar epithelium to symptoms, Barrett's esophagus remains undiagnosed in the majority of patients. Gastroesophageal reflux disease in patients with Barrett's esophagus has a more severe character and is more frequently associated with complications as compared with reflux patients without columnar mucosa. This appears to be due to a combination of a mechanically defective lower esophageal sphincter, inefficient esophageal clearance function, and gastric acid hypersecretion. Excessive reflux of alkaline duodenal contents may be responsible for the development of complications (i.e., stricture, ulcer, and dysplasia). Therapy of benign Barrett's esophagus is directed towards treatment of the underlying reflux disease. Barrett's esophagus is associated with a 30- to 125-fold increased risk for adenocarcinoma of the esophagus. The reasons for the dramatic rise in the incidence of esophageal adenocarcinoma, which occurred during the past years, are unknown. High grade dysplasia in a patient with columnar mucosa is an ominous sign for malignant degeneration. Whether an esophagectomy should be performed in patients with high grade dysplasia remains controversial. Complete resection of the tumor and its lymphatic drainage is the procedure of choice in all patients with a resectable carcinoma who are fit for surgery. In patients with tumors located in the distal esophagus, this can be achieved by a transhiatal en-bloc esophagectomy and proximal gastrectomy. Early adenocarcinoma can be cured by this approach. The value of multimodality therapy in patients with advanced tumors needs to be shown in randomized prospective trials.

    Notes: Abstract Gastroesophageal reflux disease (GERD) is one of the most frequent benign diseases of the gastrointestinal tract and in some cases the diagnosis may be very difficult. There are many diagnostic procedures but none of them could prove or definitely exclude the disease. The 24-h pH-monitoring is the “gold standard” for detection of gastroesophageal reflux and in many patients the reflux correlates with the GERD. The evaluation of a diagnostic method has to be done in a similar manner to the evaluation of therapeutic study (phase 1 to phase 4). For the definition of the “gold standard” for detection of a special diagnosis (e.g., the gastroesophageal reflux disease), the results of phase 3 studies for different methods had to be compared. The method with the best values for sensitivity and specificity is yet to be discovered. Until now, pH monitoring has been the gold standard for the diagnosis of GERD. However, there are many problems connected with using this method in clinical practice.

    Description / Table of Contents: Zusammenfassung Anhand cities Patientenkollektivs von 184 Patienten mit diffuser Peritonitis wurden 46 Variablen in einer uni- und multivariaten Analyse auf ihre prognostische Relevanz für das Überleben der Patienten überprüft. Dabei zeigten in der univariaten Analyse folgende Parameter eine signifikante Korrelation mit dem Verlauf: Lebensalter ≥70 Jahre, heptatogene und kardiale Vorerkrankung, nicht erfolgte Fokussanierung bei 1. Operation wegen Peritonitis, Kreislaufinstabilität, pulmonales Versagen, Hyperbilirubindmie, Thrombozytopenie, erhöhtes Serumkreatinin und eingeschränkte Kreatinin-Clearance zu Behandlungsbeginn sowie der Nachweis von Pseudomonas aeruginosa im Peritonealexsudat und von Candida albicans hämatogen im Therapie verlauf. In der multivariaten Analyse erwiesen sich in hierarchischer Ordnung die chirurgische Fokussanierung bei der 1. Laparotomie wegen Peritonitis, das Serumkreatinin bei Krankheitsbeginn, Patientenalter ≥70 Jahre und die hepatogene Vorerkrankung als unabhängige Variable mit signifikanter prognostischer Relevanz für das Überleben der Patienten.
    Notes: Summary In order to evaluate their prognostic relevance for survival 46 variables were submitted to univariate as well as multivariate analysis in a group of 184 patients with diffuse peritonitis. In the univariate analysis a significant correlation with the outcome was found for the following parameters: age ≥ 70 years, preexisting hepatic or cardiac disease, no eradication of the primary source of infection at first laparotomy for peritonitis, cardiovascular instability, respiratory failure, hyperbilirubinemia, thrombocytopenia, elevated serum creatinine and diminished creatinine clearance at the beginning and proof of pseudomonas aeruginosa in the peritoneal exsudate and of candida albicans in the blood culture during the course of the peritonitis. In the multivariate analysis the surgical eradication of the primary source of infection at the first laparotomy for peritonitis, serum creatinine at the beginning of peritonitis, age ≥ 70 years and a preexisting hepatic disease proved to be the independent variables with significant prognostic relevance for survival of the patients.

    Description / Table of Contents: Zusammenfassung Durch die Einführung der laparoskopischen Cholezystektomie ist die Frage nach dem Einfluß der Gallenblasenentfernung auf die Entstehung von kolorektalen Karzinomen (CR-Ca) erneut aktuell geworden. Bisher vorliegende Studien zeigen widersprüchliche Ergebnisse. Durch eine Metaanalyse getrennt nach Studienart (prospektiv, retrospektiv) wurde die Häuptfragestellung „Wird das Risiko an einem kolorektalen Karzinom zu erkranken durch die Cholezystektomie erhöht?” untersucht. In den prospektiven Matched-pairs-Studien wurden 1 158 Patienten mit Cholezystektomie (CHE) mit 1 222 Kontrollen (Ko) verglichen. Das relative Risiko (RR) war mit 1,48 nicht significant erhöht. In 4 prospektiven Kohortenstudien wurde die Häufigkeit des CR-Ca von 22 783 Patienten mit CHE verglichen mit der zu erwartenden Häufigkeit (RR = 0,99). In den retrospektiven Studien wurde die Häufigkeit einer vorhergehenden CHE bei 11 797 Patienten mit CR-Ca mit der Häufigkeit bei 33 940 Kontrollen ohne CR-Ca verglichen. Die berechnete „odds ratio” (O. R.) der Metaanalyse betrug 1,15, was eine signifikante aber klinisch nichtrelevante Risikoerhöhung darstellt. Ähnliche Werte ergaben sich für die getrennte Auswertung nach Geschlecht sowohl in der Analyse der prospektiven Studien mit einem RR von 0,99 für Frauen and 1,00 für Männer und für die retrospektiven Studien mit 1,17 (p 〈 0,05) für Frauen und 1,09 (n.s.) für Männer. Die Ergebnisse unter Berücksichtigung der Lokalisation des Tumors zeigen für die prospektiven Untersuchungen weder für das Kolon Ca noch für das Rectum Ca signifikante Risikoerhöhungen. Nur in der Analyse der retrospektiven Studien ergibt sich für das Kolon Ca eine signifikante Risikoerhöhung (O. R. = 2,12, p 〈 0,001) und dies läßt sich insbesondere für Karzinome des rechten Hemikolons nachweisen (O. R. = 1,52, p 〉 0,001).
    Notes: Abstract The number of patients subjected to cholecystectomy has increased since the introduction of laparoscopic methods. Therefore, the question of an association between colorectal cancer (CR-Ca) and cholecystectomy (CHE) is again topical. Several studies have been performed investigating the possibility of a link between cholecystectomy and large bowel cancer. The findings recorded in these studies have been varied and in some cases contradictory. In meta-analyses of the different types of studies (prospective and retrospective) the main question, “Is the risk of colorectal cancer higher after cholecystectomy?” was examined. In prospective matched-pairs studies, 1158 patients who had undergone CHE were compared with 1222 controls. The relative risk (RR) was 1.48, and this result was not significant. The four prospective cohort studies compared the frequency of CR-Ca of 22 783 CHE patients with the expected frequency in the population (RR = 0.99). The retrospective studies compared the frequency of previous CHE in 11797 patients with CR-Ca with the frequency in 33 940 controls without CR-Ca. The calculated odds ratio (O. R.) of the meta-analysis was 1.15, a significant but not clinically relevant increase in risk. Similar results was shown for evaluation of sex difference both in the prospective studies, with an RR of 0.99 for women and 1.00 for men, and in the retrospective studies, with a RR of 1.17 (p 〈 0.05) for women and 1.09 (n.s.) for men. The results for different location of the tumour show no significant risk differences in prospective studies either for the colon or for the rectum. Only the meta-analyses of retrospective studies also demonstrate a significant increase in risk of carcinomas of the colon (O. R. = 2.12, p 〈 0.001) and for the right hemicolon (O. R. = 1.52, p 〈 0.001).
