[Comparative studies of local recurrence following sphincter preserving anterior rectal resection and primary rectal excision 1980-1983]. / Vergleichende Untersuchungen der løkalen Rezidive nach sphinktererhaltender anteriorer Rektumresektion und primärer Rektumexstirpation der Jahre 1980-1983.

From May 1980-May 1983, 57 patients suffering from carcinoma of the distal part of the sigmoid colon and the rectum located 7 to 20 cm above the anus had anterior resections, with continuity being restored. 19 local recurrences could be demonstrated by a follow-up made in November 1983. In a group of 23 cases where the tumour was located between 7 to 10 cm above the anus 12 recurrences (56%) were found, which were not caused by the degree of malignancy or carcinous invasion of the intestinal wall. In the other group of 27 cases with the tumour located between 11 and 15 cm above the anus we found 6 local recurrences (22%), mostly in high risk tumours. Comparing the total recurrence rate of 36% within 34 months after anterior resection with a mortality rate of 18% after exstirpation of the rectum (18% within 36 months from 986 patients between 1960 to 1981) we came to the conclusion that tumours situated lower than 15 cm from the anus should only be extirpated, not resected.

[Benign tumors of the esophagus and stomach]. / Die gutartigen Tumoren des Osophagus und des Magens.

From the tumors of the oesophagus studied, 30% were found to be benign. They occurred in a ratio of 2:1 predominantly in men with an average age of 37,1 years compared to 52,5 years in women. The symptoms were unspecific and the prognosis was quo ad sanationem very good. Only in one case did a neurofibroma relapse explosively with in 4 months and was already inoperable at the time, when the new diagnosis was made. The percent of benign stomach tumors amounted to 2,6%. Tumors of the mucous tissue behaved differently than the neurogenic and mesenchymal ones. The former became noticeable mainly due to epigastric complaints, the latter due to haemorrhages. Epithelial tumors occurred, with a ratio of 2:1, more often in women, but without any difference in age. Mesenchymal and neurogenic tumors occurred in almost the same sex ratio, but at an average age, which was 18 years higher in women. Solitary stomach polypi can mostly be removed endoscopically, whilst all other benign oesophagus and stomach tumors must be removed by operation due to the symptoms and the dignity of the tumor, which is seldom clear.

[Intestinal gas gangrene originating from the gallbladder: diagnosis, therapy, report of 2 cases]. / Intestinaeler Gasbrand ausgehend von der Gallenblase: Diagnose, Therapie, Darstellung von 2 eigenen Fälen.

The problems of diagnosis and therapy of gas gangrene of the gastrointestinal tube and the gallbladder are discussed. 2 cases of gas edema of the gallbladder due to clostridium perfringens are reported. One of the patients survived. The early diagnosis of gas gangrene is important because of the extraordinary way of infection and the necessary early surgical and medicamentous therapy.
