[Colonic diverticulitis: diverticulitis with complications and its treatment (author's transl)].

Complications (stenosis, intestinal obstruction, abscess or fistula formation, inflammation, etc.) of colonic diverticulitis are seen in 35% of patients affected. Multiple operative procedures involve less risk than surgery performed in a single session. The mortality in emergency surgery is reported to be up to 40%, while subsequent resection of the diseased colon involves the usual mortality of surgery on the colon, i.e. 1.5-9%. The vital factor in this illness is the earliest possible surgical treatment of the diseased diverticulum, so that the extremely problematical complications can be avoided.

Investigation of the abnormal low-density lipoproteins occurring in patients with obstructive jaundice.

The abnormal lipoproteins of the density range 1.019-1.063g/cm3 occurring in the plasma of patients with obstructive jaundice were studied. Subfractionation of this density class by combined sodium phosphotungstate precipitation, ultracentrifugation, and column chromatography on hydroxyapatite and agarose gel yielded essentially three fractions: (1) lipoprotein-X, (2) A triglyceride-rich lipoprotein for which we propose the term lipoprotein-Y and (3) an abnormal lipoprotein, lipoprotein-B. Marked differences between these fractions with respect to electron-microscopic appearance, hydrated densities, chemical composition and immunochemical characteristics were observed. The protein moiety of lipoprotein-X consisted primarily of apolipoprotein-C and albumin. Lipoprotein-Y showed, in addition to apolipoprotein-C, the presence of apolipoprotein-B. The 'lipoprotein-B' fraction isolated from sera of these patients had higher triglyceride and free cholesterol contents than that of normal individuals and an unusually high content of apolipoprotein-C. The relative distribution of lipoprotein-X, lipoprotein-Y and 'lipoprotein-B' varied from patient to patient. The importance of considering the existence of lipoprotein-Y in screening patients for cholestasis by the lipoprotein-X test is discussed.

[A prospective study on the occurrence of postoperative thrombosis of leg-veins and the possible influence of aescin in its prevention (author's transl)].

Based on the frequency of subclinical, postoperative thrombosis which we detected using radio-iodine-tagged fibrinogen (125I-fibrinogen) in 2 comparable test groups of 100 female patients each, we were able to compare the effectiveness of Aescin (Reparil) to the untreated group. Whereas only 16 patients in the Reparil group were thrombose-positive we found 27 such cases in the control group. The analysis of these data shows Reparil to be of distinct advantage when compared to the untreated group.

[Endometriosis of the colon (author's transl)].

This report is concerned with a twenty-five year old female with endometriosis of the recto-sigmoid-colon. Due to medication intolerance a trial with hormone therapy had to be discontinued. After several years of illness an ileus and ureter-stenosis developed and several operations were necessary to alleviate these conditions. A survey of the frequency and localization of extragenital endometriosis followed by a discussion of pathogenesis, clinic and alternatives of therapy.

[Gastroscopy -- a routine procedure in the investigation of diseases of the stomach (author's transl)].

After a short review of the development of endoscopic investigations, the technique of gastroscopy is described and the indications for this procedure are pointed out. This procedure is of equal importance as radio-diagnostic measures in the routine investigation of stomach diseases and is of particular value when used as an emergency procedure and in the follow-up of patients after gastric operations. It also offers great advantages in the diagnosis of stomach tumours since biopsy material can be obtained from the lesion. Stomach haemorrhage due to gastric erosion, oesophagitis and the Mallory-Weiss syndrome are best diagnosed by gastroscopy. There are practically no contraindications to gastroscopy. The only precluding factor being an uncooperative patient. It is not contraindicated in patients with oesophageal varices or deformity of the spinal column. Complications are very rare. In the case of emergency gastrocscopy, shock must be counteracted and the blood pressure normalized before the investigation can be performed.

[Carcinoma of the pancreas: curative operations (author's transl)].

In 1898 the first radical operation for carcinoma of the pancreas was performed by Codivilla in Bologna. Kausch followed in 1913 and Whipple perfected the technique of duodenopancreatectomy. The central position of the pancreas causes technical difficulties. Carcinoma of the head of the pancreas frequently causes icterus, which quite often limits the primary radical operation. Radical removal of carcinoma of the head of the pancreas is only possible if the limits of the organ have not been passed. Preservation of a part of the pancreas is essential for the metabolism. The average primary mortality of the radical operation is around 25 percent, having fallen significantly in the last few years. The 5-years recovery rate is a bare 10 percent.
