Summary 52% of recurrences of the group with regular check-up after curative surgery for colonic carcinoma were diagnosed within the first postoperative year compared to 38% of the patients without medical control. Diagnosis of recurrent disease was made in 75% during a regular check-up, i. e. in state of asymptomatic relapse. Patients without postoperative control attended a physician in 96% because of symptomatic recurrence. 31% of the controlled group were free of lymph node involvement or metastases at the time of secondary procedure as compared to 20% of the group without check-up. 37% of secondary operations could be performed curatively for the patients with examinations compared to 17% of the patients without control. Five-year-survival-rate after secondary procedure was 11 % for the group with check-up and 0% for the patients without control. Therefore the high personal, financial and temporal expense and the handicap of patients by a regular postoperative check-up seems justified in case of colonic carcinoma.

Summary In this study the incidence of recurrence in radical procedure for carcinoma of colon is more than 37.4%. Of 100 patients undergoing second laparotomy because of recurrence 33% could be resected curatively. The rate of recurrence was independent on sex, negatively correlated with age and positively correlated with tumor stage of former operations. Curative operations located at the ascending colon and hepatic flexure had less recurrences than others. Second operations in curative aims were twice as successfull in men than in woman and equally possible in all decades. Results of recurrences of splenic flexure and transverse colon were better than other locations. Tumors of early stages relapsed later. The probability of a radical procedure in recurrence related operations was better in those cases with a long recurrence-free interval. The resectability ± rate and tumor stage of second-look operation were depending on tumor stage in the first operation. This means further history of tumor disease is determined closely by tumor stage in the first operation.

Zusammenfassung: Der Dreipunktsicherheitsgurt stellt unter den handelsüblichen Rückhaltesystemen zur Zeit den besten Schutz vor Verletzungen dar. Die Tatsache, daß ein Fahrzeuginsasse angeschnallt war, bedeutet jedoch nicht, daß er unverletzt ist. Die Kenntnis gurtspezifischer Verletzungen ist besonders im Hinblick auf die gesetzliche Anschnallpflicht in vielen europäischen Ländern wichtig.

Zusammenfassung: Bei 100 kolorektalen Anastomosen wurde das Einmalklammernahtger�t Proximate ILS verwendet. 47mal lag die Anastomose im Sigma, bei 29 Patienten im Rektum und bei 24 zwischen D�nn- und Dickdarm. Radiologisch waren 6 Nahtinsuffizienzen nachweisbar, die jedoch nur 1 mal zur Relaparotomie zwangen. Die Krankenhausletalit�t betrug 5%, t�dliche Komplikationen von seiten der Nahtverbindung wurden bei 1 Patienten beobachtet. Die durchschnittliche Operationszeit betrug 118 Minuten, technische Komplikationen von seiten des Ger�tes traten nicht auf.

Von 235 elektiven Kolonresektionen wurden 28 (11,9%) bei über 80jährigen Patienten durchgeführt. Präoperativ standen kardiale und pulmonale Risikofaktoren im vordergrund. Postoperativ verstarben 2 Patienten (7,1%). Die Letalität elektiver Kolonresektionen im sehr hohen Lebensalter ist der in anderen Altersgruppen vergleichbar.

Summary Of 982 patients with carcinoma of the stomach, radical operations (1970–1980, Surgery Clinic, University of Mainz). A number took part in standardized follow-up (215 patients) including clinical and endoscopic investigations, laboratory reports, carcinoembryonic antigen determinations, and X-ray. Fifty-one patients developed cancer recurrence or metastases, and, 20 patients underwent relaparotomy; however, only 2 of these were be cured by a second radical operation. Thus, the value of follow-up after radical gastric cancer operations seems extremely limited.
