89. Das colorectale Carcinom als chirurgischer Notfall

Paul Hermanek; Manfred Schweiger; F. P. Gall

Summary295 out of 3014 patients (9.8%) treated for colorectal carcinoma between 01/1969 and 12/1983 presented as emergencies. The postoperative mortality rate of 28% was high in the emergency group compared with 6% after elective surgery. The tumor stage was far more advanced with 27% distant metastases. The overall 37% 5-year-survival rate was significantly different from that after elective operations (57%, p.o. deaths not included). Differences were statistically not significant when respective UICC-stages were compared.ZusammenfassungBei 295 von 3014 Patienten (9,8%), die zwischen Januar 1969 und Dezember 1983 wegen eines colorectalen Carcinoms behandelt wurden, lag ein chirurgischer Notfall vor. Die p.o. Letalitat war mit 28% mehr als viermal höher als nach Elektiveingriffen (6%). Das Tumorstadium war mit 27% M 1-Fällen weiter fortgeschritten (15% bei Elektiveingriffen). Trotz einer signifikant schlechteren 5-Jahres-Überlebensrate von 37% vs. 57% fanden sich in vergleichbaren UICC-Stadien annähernd identische Überlebenskurven.295 out of 3014 patients (9.8%) treated for colorectal carcinoma between 01/1969 and 12/1983 presented as emergencies.

Kontinenz nach tiefer rectumresektion

Manfred Schweiger; W. Schellerer; G. Kuypers

In 28 patients we studied the fecal continence after low anterior resection of the rectum. After an usual proctological investigation we did in all patients measurements of the anorectal function, such as pressure measurement, electromyography and determination of the anal-rectal angle. In 12 patients a defecatogram was performed. Of the 28 patients with anastomoses lower than 8 cm only one was after 2 years still incontinent. All the other patients were completely continent. This fact could be proven objectively.SummaryIn 28 patients we studied the fecal continence after low anterior resection of the rectum.

Neben der normalen proktologischen Anamnese und Untersuchung wurde bei allen eine anorectale Funktionsdiagnostik mit Manometrie, Elektromyographie und Bestimmung des anorectalen Winkels durchgeführt. Bei 12 Patienten machen wir zusätzlich ein Defäkatogramm.Von den 28 Patienten mit Anastomosen unter 8 cm hatte nach 2 Jahren nur 1 Patient Kontinenzstörungen. Alle anderen waren voll kontinent. Diese Tatsache konnte objektiv nachgewiesen werden.

80. Das Rectumprolapsrezidiv beim Erwachsenen —Eine Analyse des Msßerfolges

Manfred Schweiger; Robert J. Meister

SummaryBetween 1969 and 1982 179 adults mit rectal prolaps were operated on by transabdominal rectopexy with dura mater implantation (modification according Wells procedure). In 15% recurrent prolapse occurred. The maximum in the development of the recurrences was in the second postoperative year. The patients with recurrence showed much more additional disturbances as constipation, irritable colon, fecal incontinence, psychotic alterations, solitary ulcers and traumas of the pelvic floor. A chance in the surgical technique (marlex instead of dura mater) and a restriction in the indication for transabdominal rectopexy is recommended.ZusammenfassungZwischen 1969 und 1982 wurden 179 Erwachsene mit Rectumprolaps durch eine transabdominelle Rectopexie mit Dura mater Implantation (Modifikation nach Wells) behandelt. In 15% kam es zu einem Prolapsrezidiv. Das Maximum der Rezidiventwicklung fand sich im 2. postoperativen Jahr. Patienten, die ein Rezidiv entwickelten, hatten in viel höherem Maße zusätzliche Störungen, wie funktionelle Dickdarmerkrankungen, Stuhlinkontinenz, psychische Störungen, Ulcus simplex sowie traumatische Beckenbodenveränderungen. Neben einer Anderung der Operations-technik (Marlex-Netz statt Dura mater) wird deshalb eine Einschränkung der Indikation zur transabdominellen Rectopexie empfohlen.

215. Anteriore Resektion statt Exstirpation beim Carcinom des mittleren Rectumdrittels —Erhöht sich mit Änderung des Operationsverfahrens das Risiko?

Manfred Schweiger; F. P. Gall; A. Altendorf

SummaryBetween 1976 and 1981 we increasingly changed our operative procedure in carcinoma of the midrectum from anteroposterior excision to the sphincter-saving anterior resection. There was no increase in postoperative mortality (1969–1975: 7%, 8/115; 1976–1980: 6.6%, 11/167). The 5-year survival rate improved (1969–1975:46% ± 11%;1976–1980:75.8% ± 10%), while the rate of local recurrence decreased (1969–1975: 29.8%; 1976–1980: 18.2%). The tumour stages during the two periods were comparable. In carcinoma of the mid-rectum an anterior resection is therefore possible without increasing the risk.ZusammenfassungIn den Jahren 1976–81 haben wir bei Carcinomen des mittleren Rectumdrittels zunehmend die Exstirpation zugunsten der spinctererhaltenden anterioren Resektion verlassen. Durch diese Änderung der Operationsmethode ist die postoperative Letalität nicht gestiegen (1969–1975 7 %, 8/115; 1976–1980 6,6 %, 11/167). Die 5-Jahres-Überlebensrate (alterskorrigiert nur RO) hat sich verbessert (1969–1975 46 ± 11 %; 1976–1980 75,8 ± 10%). Die Lokalrezidivratefiel in den beobachteten Zeiträumen von 29,8% auf 18,2%. Die Stadienverteilung der Carcinome ist gleich geblieben. Bei Carcinomen des mittleren Rectumdrittels kann daher ohne Erhöhung des Risikos eine anteriore Rectumresektion durchgeführt werden.
