    Description / Table of Contents: Zusammenfassung Drei Verfahren zur Behandlung des chronischen Ulcus duodeni wurden in einer prospektiv-konsekutiven Studie geprüft. Beim Konzept I, der individuellen Ulcuschirurgie, wurde je nach Säureanalyse, Allgemeinzustand und Lokalbefund die selektive Vagotomie mit Drainage, mit Antrektomie (B-I) oder mit 2/3-Resektion (B-II) durchgeführt. Beim Konzept II immer die selektive Vagotomie mit Pyloroplastik und beim Konzept III ausschließlich die proximal-selektive Vagotomie ohne Drainage. Prä- und postoperativ wurden die Patienten in der Follow-up-Klinik untersucht, die Follow-up-Raten lagen dabei über 90 %. Die Diagnosesicherung erfolgte durch Endoskopie, Röntgen und Magensaftanalysen in standardisierter Weise. Die Analyse der Ergebnisse wurde anhand der Therapieversager nach Troidl durchgeführt. Behandelt wurden im Konzept I= 64 Patienten, im Konzept II = 62 Patienten und im Konzept III= 110 Patienten. Die Letalität betrug in allen 3 Konzepten 0 %. Für 1 Jahr Beobachtungszeit ergaben sich: Rezidivulcera bei I = 0 %, bei II= 3 %, bei III= 4,5 %. Beschwerden (Visick III und IV) gaben an bei I = 14 %, II= 12,8 %, III= 4,5 %. Syndromwandel nur 1 %, bei III. Keine Säurereduktion bei I= 0 %, II = 4,9 % und III= 16,4 Die selektiv-proximale Vagotomie ist derzeit als kleinster und schonendster, mit dem geringsten Aufwand verbundener Eingriff und gutem klinischen Erfolg beim chronischen Ulcus duodeni zu favorisieren.
    Notes: Summary In a prospective study 3 surgical concepts were used to treat patients with chronic duodenal ulcer. In concept I 64 patients were treated with ‘individual ulcer surgery’, i. e. depending on the general condition of the patient, the local intraoperative situation and preoperative acid output, either selective vagotomy with pyloroplasty, with antrectomy (B-I) or B-11 gastrectomy were used. In concept II 62 patients were treated with selective vagotomy and pyloroplasty. In concept III 110 patients with highly selective vagotomy were treated without drainage. The conditions were diagnosted and the patients were treated in a standardized manner. Follow-up rates were 90 % and above and the results were analyzed according to Troidl's definition of operative failures after 1-year follow-up. Lethality was 0% in all concepts (I-III). Recurrent ulcer: I = 0 %, II = 3 %, III = 4.5 %. Complaints with Visick-classifications III and IV: I = 14 %, II = 12.8 %, III = 4.5 %. Changing symptoms: I = 0 %, II= 0 %, III =1 %. No acid reduction: I = 0 %, 11= 4.9 %, III =16,4 %. The lowest recurrence rate and best acid reduction was concept I, the best overall clinical outcome concept III. Highly selective vagotomy without drainage is preferred as the least major and most careful procedure at the moment.

    Notes: Summary A retrospective review of 78 patients who had undergone endoscopic gastrostomy and 22 patients who had undergone Stamm gastrostomy was carried out. The mean operative time for the Stamm gastrostomy group was 63 min, while that for the endoscopic gastrostomy group was 26 min. One operative complication — bleeding — requiring reoperation occurred in the Stamm gastrostomy group. The incidences of aspiration, pneumonia, wound infection, and mortality were significantly higher in the Stamm gastrostomy group. We conclude that percutaneous endoscopic gastrostomy is the preferred technique for long-term enteral nutrition.

    Notes: Summary Surgeons are increasingly using endoscopy to place transabdominal feeding tubes for enteral nutrition or gastric decompression. A possible extension for the application of this new technique is the direct placement of the feeding tube into the duodenal bulb. Two patients are presented in whom percutaneous endoscopic duodenostomy was successfully performed, although percutaneous endoscopic gastrostomy was not possible. It shows that this new method is technically possible. In both patients the positive influence of this technique on the patient's quality of life could be shown using the Spitzer Quality of Life Index and the Karnofsky Performance Status. Enteral nutrition was maintained for more than 6 weeks.

    Notes: Summary In a prospective clinical trial, 26 consecutive patients underwent endoscopic pneumatic dilatation over a 10-year period. Dilatation was achieved by means of a ballon attached to a normal gastrointestinal fiberscope. With the endoscope in an inverse position, the device was placed in the cardia and the dilatation process was monitored macroscopically. Before dilatation, patients suffered from dysphagia (92%), reduced speed of swallowing (100%), symptom aggravation under stress (73%), weight loss (50%), aspiration, pain, regurgitation, and vomiting. After dilatation and long-term follow-up (mean of 5 years), symptoms could be markedly reduced, especially the speed of eating and symptom aggravation under stress. Excellent and good results (Visick scale) were achieved in 76%. Fair results were achieved in 20%. To date, perforation and other complications have not occurred. Mortality was zero. Our series was an uncontrolled trial, so the results are hardly comparable to other studies. Furthermore, the small number of patients in our study represents a weak point with regard to complications. We conclude that the main advantages of the procedure are its simplicity and practicability. The simple procedure may be the method of choice in elderly patients. Of course, no final decision can be made until a well-designed controlled trial has been carried out.

    Description / Table of Contents: Zusammenfassung Nach strenger Definition der benignen Magenausgangsstenose durch: verzögertes Erbrechen, Symptomwandel, Gewichtsverlust und intraoperative Prüfung mit Hegarstiften (〈 14) finden sich unter 619 operierten Ulcuspatienten 2,2% echte Stenosen. Operativ werden diese Patienten ausnahmslos durch SPV und digitale Magenausgangsdilatation über eine Gastrotomie behandelt. Bei Follow-up-Untersuchungen bis zu 10 Jahren ergab sich bei keinem Patienten die Indikation zur Reoperation. Alle Patienten zeigten Visick-Klassifikationen von I und II. Zusammen mit der SPV ergibt die digitale Magenausgangsdilatation bei Magenausgangsstenose gute klinische Ergebnisse bei Langzeit-Follow-up.
    Notes: Summary According to a strict definition of a benign gastric outlet obstruction i.e. delayed vomiting, changing of symptoms, weight loss and intraoperative test by Hegardilators (〈 14), 2.2% real stenoses among 619 operative treated duodenal ulcer patients were found. All patients were treated by SPV and digital dilatation of the stenosis through a gastrotomy. During up to a 10 year follow-up no reoperation was necessary. All patients showed Visick-classification of I and II. In conclusion SPV with digital dilatation showed good clinical results for patients with benign gastric outlet obstruction in long-term follow up.

    Description / Table of Contents: Zusammenfassung Die percutane endoskopische Gastrostomie eignet sich für Patienten mit intaktem Gastrointestinaltrakt, die eine Langzeiternährung benötigen. Bei Endoskopie des Magens wird unter Insufflation die Bauchwand transilluminiert. Danach Lokalanaesthesie im linken oberen Abdominalbereich und Probepunktion des Magens. Ein 12 Ch. Foley-Katheter wird durch direkte Punktion des Magens über eine Split-Kanüle eingebracht. Nach Entfernen der Split-Kanüle und Blocken des Katheterballons wird dieser an der Bauchhaut mit leichtem Zug befestigt. Bisher traten bei 8 Patienten keine Komplikationen auf. Ein Patient konnte 1 Jahr über die Gastrostomie ernährt werden.
    Notes: Summary Patients who have an intact stomach and small bowel, and who need long-term enteral nutrition, can be nourished by percutaneous endoscopic gastrostomy. During endoscopy of the stomach, air is insufflated and the abdominal wall is transilluminated. Local anesthesia and test puncture of the stomach in the left upper abdomen are used. A 12 Charriére Foley catheter is introduced through direct puncture of the stomach with a split cannula. After blocking the catheter balloon, the catheter is fixed with slight tension to the skin of the abdominal wall. In eight patients no complications have occurred so far. One patient was fed through the gastrostomy for 1 year.

    Description / Table of Contents: Zusammenfassung Für die chirurgische Therapie von Colon-Carcinomen werden die eigenen Konzepte vorgestellt. Beispielhaft wird im Film eine tiefe anteriore Rectumresektion dargestellt. Ein suprapubischer Blasenkatheter wird angelegt. Die Resektion des Darmes erfolgt nach Darstellung des Ureters and einer ausgiebigen systematischen Lymphadenektomie. Die A. mesenterica inferior wird ursprungsnah ligiert. Die Anastomose wird mit dem EEA-Nahtgerät vorgenommen and auf Wasserdichtigkeit geprüft. Eine Coecalschlauchfistel ergibt eine vorübergehende Entlastung der Anastomose. Für eine enterale Ernahrung wird eine Feinnadelkatheter-Jejunostomie mit einem 10 cm langen Kathetertunnel am oberen Jejunum eingelegt.
    Notes: Summary Our surgical concepts for the treatment of colon cancer are demonstrated. As an example, low anterior resection of a rectal carcinoma is shown. After insertion of a suprapubic bladder drain, resection of the colon starts after identifying the left ureter with extensive systematic lymphadenectomy. The inferior mesenteric artery is ligated near the aorta. The anastomosis is done by an EEA stapling device and is tested to make sure it is water-tight. A coecal fistula divides the fecal stream. For immediate postoperative enteral nutrition a fine-needle-catheter jejunostomy is inserted; therefore, a 10 cm tunnel is constructed with a special split cannula in the upper jejunum.
