[Operative therapy of the pilonidal sinus; 115 controlled patients (author's transl)].

The operative results of 115 patients with pilonidal sinus are described. The patients were controlled in 1977, 2 to 11 years after surgery. Only small, non-infected pilonidal sinuses should be radically excised followed by primary suture and Redon-drainage. For extended sinuses and for recurrences the best results are obtained when the wound is left open or marsupialisation is applied. Pilonidal sinus-abscesses should be incised. This simple procedure resulted in primary healing in 23% of our patients.

[Social medical aspects of patients with a permanent colostomy (author's transl)].

Problems of 39 patients with permanent colostomies/ileostomies are investigated one up to seven years after having got the anus praeternaturalis. The postoperative problems of everyday life are various and often serious, they are the more severe, the less patients had been informed preoperatively and the older the patients are. Younger and more intelligent patients integrate the colostomy easier and more quickly in their everyday life. Very useful for rehabilitation is the close contact between patient and the surgeon, respectively special colostomy-consulting hours.

[Contribution to biliobronchial fistula (author's transl)].

A case report has been made on a bronchobiliary fistula which was caused from an unspecific liver abscess. The causal therapy was the drainage of the liver abscess. The fistula then healed spontaneously. A primary thoracic sanitation of the fistula is in such cases not indicated.

Assay and characterization of serum-stimulated lipolytic activity in homogenates of human adipose tissue.

An assay of lipolytic activity in human adipose tissue is described, in which native homogenates of the adipose tissue yield the enzyme, as well as the triglyceride substrate, and the emulsifying phospholipids. The lipolytic activity in the presence of serum is characterized mainly as lipoprotein lipase activity by a pH-optimum of 8.0, by the fact that serum is necessary for full activity, and that it is inhibited by 1 M NaCl and by protamine. At serum concentrations of higher than 50% a marked inhibition of the lipolysis is observed. Noradrenaline, insulin, and heparin have no effect on the serum-stimulated lipolytic activity.

[The Dieulafoy's ulcer (author's transl)].

In the years 1971-1976 five patients with Dieulafoy's ulcer were operated upon succfully in the Innsbruck University Surgical Clinic. A high consumption of alcohol and tobacco was an outstanding feature in the history of all these patients. Gastroscopy is the diagnostic procedure of choice in this disease; it should be done during the acute phase of hemorrhage since the rather minor morphological changes often cannot be detected when they are not bleeding. Occluding the bleeding vessel by stitches is the therapy of choice. Procedure including resections, especially a socalled "blind" resection, do not seem to be justified. If the bleeding vessel cannot be found during endoscopy a large gastrotomy ought to be done with careful inspection especially of the upper third of the stomach. Our patients were followed up to 64 months; they all are well and without complaints. Prognosis thus seems to be very good if a correct diagnosis is established quickly and if surgery is done adequately.

[Carcinoma in Zenker's diverticulum (author's transl)].

Carcinoma arising in Zenker's diverticulum have to be thought of, if it has been present for long time, if there is blood mixed the food regurgitated, and if there are irregularities of the wall of the diverticulum to be detected radiologically. In most cases resection is the method of choice. A case of a 70 year old patient is reported, who harbored a microcarcinoma in the mucosa of a resected Zenker's diverticulum. Surgery was done 10 years ago and no recurrence or mestastases have been observed since.

[The problem of post-operative complications after colonic surgery because of malignant tumors (author's transl)].

Post-operative complications after colonic surgery because of malignant tumours were analysed in 412 patients from 1961 to 1974 at the Surgical-Clinic of Innsbruck University. 42% of the patients had postoperative complications. 60% of these complications were directly due to surgery, 40% indirectly. Attention should be paid to the fact that colonic surgery in particular has a high rate of complications, i.e. 76% of these cases seen in relation to 38% of routinely operated patients. With reference to all patients 18 different complications were observed. Causes of these complications and prophylactic treatment, likely to decrease the rate of lethality and complications are discussed.

[Drainage-dependent continence disorder after deep resection of the anterior rectum].

Anorectal continence following low anterior resection in 37 controlled patients from the University Hospitals of Innsbruck, Department of Surgery, in the years 1970 to 1974 is described. Of these 37 patients, 10% were partially incontinent for from 18 to 24 months. It is pointed out that the partial incontinence of these patients is due to the extensive perirectal-perianal drainage. The low anterior resection can be called continence-saving, if a too extensive perirectal-perianal drainage is avoided and the criteria of the operation are considered.

[Mathematical-physical deliberations over the development of artificial-anus prolapse (and the therefrom derived attachment technic for the artificial anus)].

It is established that most colostomies which lead to prolapse because of imperfect operative technique are shaped like a truncated cone. Mathematical-physical considerations show mechanisms which in such cases can produce prolapse of the colostomy. Considering these criteria and recent clinical experience, a suitable colostomy is described.

[Malignant tumors of the colon: statistical and clinical aspects (author's transl)].

Between 1961 and 1974 at the University Hospital Surgical Clinic at Innsbruck, 991 cases of malignant tumors of the colon have been treated. Statistically a significant increase is proved in the number of these patients above the age of fifty in the Tyrolean population during this period. On the other hand the percentage of colon-tumors is decreasing with the age in patients younger than fifty. 412 out of these 991 cases could be analysed very carefully. The malignant tumors have been studied, among other respects, in relation to the localisation in the particular part of the colon, the frequency in the different ages and sexes. Specially the symptoms due to the particular localisation of the tumor are stressed. It is also noticed that the long case history, mainly because of the patients' own negligence, plays a decisive part in the unsatisfactoring number of cured. Some measures are mentioned, which with the so far got knowledge and science can improve the final therapeutic results.

[Polychemotherapy of the advanced and metastasizing carcinoma of the breast].

The course of treatment with polychemotherapy for the progressed and metastasized breast-carcinoma is discussed. The therapy with cytostatics must be continued for the patients entire life. A sample of 27 patients from the Chir; Univ.-Klinik Innsbruck with a course of treatment lasting from 15 to 29 months (October 1973 resp; December 1974 to February 1976) showed a success rate of 81%.

[Clinical aspects of Hochenegg's draft procedure].

A report concerning the follow-up examinations of the 14 patients with rectum cancer from the University Surgical Clinic in Innsbruck, Austria, who from 1961-1974 were operated on using Hochenegg's technique. Interestingly enough, it was noticed that when the height of the anastomosis was less than 5 cm from the anal ring, a partial incontinence appeared (in 3 of the 14 patients) and when it was more than 5 cm from the anal ring, a total continence was assured. A relapse was observed three times in the tumor cases type C2 and D (Duke). Post-operative complications occurred in 4 cases, none being life-threatening. The indications of this technique will be discussed.
