[Ultrasonically guided percutaneous fine-needle biopsy (author's transl)].

A new method is described of doing fine-needle biopsies, under continuous visual control with real-time ultrasonic guidance, of the neck, thoracic and abdominal regions. The method decreases the risk of needle puncture and improves the yield of material obtained. It is simple and hardly stresses the patient, pain being only slight and momentary. It can be easily repeated. It is particularly useful for amniocentesis in obstetrics because it employs the shortest possible pathway.

[Salmonella colitis].

Salmonella colitis is defined on the basis of 3 case reports and 75 well-documented cases from the literature. Salmonella colitis is an acute ulcerative colitis occurring in enteric salmonellosis. There is complete clinical and endoscopic remission within 4--8 weeks and no relapse. The disease is to be distinguished from idiopathic ulcerative colitis in a salmonella carrier state. The difficulties of this differential diagnosis are demonstrated in a further case report.

[Drug-induced esophageal ulcers].

In cases without a history of gastrointestinal or cardiac disease, acute odynophagia prompts the tentative diagnosis of drug-induced esophageal ulcer. Possible causes are tetracycline, clindamycin, emepronium bromide, potassium chloride, etc. Other diseases such as carcinoma can be ruled out by endoscopy and biopsy. To avoid such esophageal lesions drugs should be taken with sufficient fluid and not immediately before bedrest.

[Clinical pathology of colonic mucosal polyps].

Of 636 polyps removed during endoscopy between 1973 and 1975 at the University Hospital, Zurich, 36 (5.5%) were of the hyperplastic and 18 (2.8%) of the juvenile type. One polyp was seen in a female patient with Peutz-Jeghers syndrome. The vast majority of the polyps (581, 91.5%) were neoplastic in origin; 70% were tubular adenomas, 16% villous adenomas, and 14% intermediate forms or tubulo-villous adenomas. On the basis of a continuous spectrum in histologic structure and similar cellular dedifferentiation, these three types of adenoma may be viewed as different forms in the development of the same neoplastic process. Hyperplastic and hamartomatous polyps are innocuous, whereas the neoplastic forms may well turn aggressive. Malignant change was observed in 5.1% of our material, particularly in villous adenomas and in polyps exceeding 1 cm in diameter. The presence or absence of invasive growth through the muscularis mucosae is of prime importance for therapy. In accordance with WHO nomenclature, the term carcinoma is used only in the presence of such infiltration. If, in addition, the tumor tissue is not well differentiated, additional segmental resection may be required. The term "focal carcinoma" is no longer in use and has been replaced by "severe focal atypia". In these cases, primary polypectomy for diagnostic purposes is also the optimal therapy, and is as effective here as in cases of benign adenoma.

[Primary malignant lymphoma of the stomach. Analysis of 38 cases].

A retrospective analysis is presented of 38 cases of malignant lymphomas of the stomach, 20 of the reticulum cell type, 6 lymphoblastic, 6 lymphocytic and 4 mixed forms. Two patients had a primary Hodgkin's malignant lymphogranuloma. A follow-up was obtained for 35 patients. There proved to be no significant difference between the symptomatology of carcinoma and lymphoma of the stomach. In patients with lymphomas only signs of stenosis were missing, although the majority of the tumors were located in the antrum. As a consequence of the extreme tendency of the lymphomas to exulcerate (89%), the mean duration of symptoms of 21/2 months (patient's delay) is shorter than that for carcinomas. Malignant lymphomas of the stomach are very difficult to identify as such by radiology and endoscopy, because of their uncharacteristic macroscopic appearance. The best diagnostic method has proved to be endoscopic wire-loop biopsy, which serves to obtain adequate material for histology. An unexpected finding was that at the time of operation half of the patients had clinical stage I E. This indicates that lymphomas remain limited to the stomach longer than carcinomas do. The prognosis depends on both histological type and clinical stage. It is somewhat better than that of nodal malignant lymphomas. The 5-year survival rate of all cases with malignant lymphoma of the stomach is 31%.

[Large colonic polyp: endoscopic or surgical removal?].

93 neoplastic polyps measuring more than 2 cm in diameter have been removed from the colon by endoscopy. 15% of the polyps showed severe atypia (focal carcinoma), and in 15% an invasive carcinoma was found. Polypectomy was complicated in 14 cases by bleeding, in 12 cases it was cured by endoscopy. In 1 case in which the colon was injured by coagulation the lesion healed spontaneously. The surgery rate due to complications of the endoscopic removal procedure or due to invasive carcinoma was 7% for the polyps with a diameter of 2-3 cm, 15% for those of 3-5 cm and 50% for polyps with a diameter of more than 5 cm. It is therefore suggested that neoplastic polyps of more than 5 cm in diameter should be removed by endoscopy in high risk patients only.

[Angiodysplasia of the colon: diagnosis and therapy].

Angiodysplasias of the colon are rare causes of intestinal bleeding. Diagnosis is by angiography or colonoscopy. In 6 patients with severe anemia in whom conventional methods had failed to reveal the source of bleeding, colonoscopy demonstrated angiodysplasias in the cecum or ascending colon. They were treated endoscopically. In a follow-up period of 3 months to 4 years only 1 patient has sometimes suffered occult fecal blood loss, but is adequately treated by oral iron therapy. No patient has had a severe recurrence of bleeding, nor was colonic resection necessary. It is concluded that endoscopic therapy of angiodysplasias is a valuable alternative to surgery with low risk and high efficiency.

[Nonspecific ulcer of the colon: a report on 12 endoscopically diagnosed cases].

Report on 12 patients with nonspecific ulcers of the colon diagnosed by colonscopy and biopsy. In 10 patients the course was favorable with conservative management. In 2 patients the symptoms were aggravated; in both patients this was due to a penetrating malignant tumour diagnosed at laparotomy a few weeks later. It is proposed that nonspecific ulcers of the colon should be managed conservatively. Further investigations and laparotomy are indicated only when symptoms progress.

[Ambulatory management of chronic alcoholism].

Alcoholism frequently goes undiagnosed in day-to-day medical practice because the possibility of successfully treating alcoholics on an out-patient basis is too little known. Concepts of how alcoholism arises usually relate to an isolated individual and, therefore, do not cover the whole reality of this multifactorial disease. Treatment in a "social network" presupposes that the patient's problems are understood as disturbed interactions with his environment. With this concept in mind it is possible to approach the essential conditions of the disease. 484 patients have been treated according to this program. 352 (72.7%) were followed up for an average of 8.3 years (range 2--19 years). 37.4% were in complete remission, 33.7 had markedly improved and 28.9% were unchanged or worse.

[Pseudocysts and retention cysts in acute and chronic pancreatitis (author's transl)].

42 cases of pancreatic cyst in acute (22 cases) pr chronic (20 cases) pancreatitis were seen between 1962 and 1976. Analysis of the case data revealed the following: (1) exact assignment of the cyst to acute or chronic pancreatitis is often possible only by long-term observation; (2) the cysts of chronic pancreatitis are not a uniform group: some (8 cases) apparently occurred in acute pancreatitis through necrotic episodes (pseudocysts), others (12 cases) by a retention mechanism; these "retention cysts" develop later in the course of chronic pancreatitis than the pseudocysts and produce a different clinical picture with better prognosis; (3) barium meal and retrograde cholangiopancreatography proved of diagnostic value' (4) if the cysts persist for more than six weeks operation is indicated because of the high incidence of complications.
