[Functional and morphological studies on diverticulosis of the large bowel].

In comparison to the normal colon, longitudinal and circular musculature in diverticular disease (DD) was investigated--regarding motility and morphology--and a comparative measurement between musculature and mucosa was also performed with following results: 1. Only the tenia in DD revealed a spastically contracted muscle. 2. There was a ribbon formation due to contraction only in tenias of DD, although there was hypertrophy in both muscle groups. 3. The longitudinal muscle in DD was found to be shortened.

[Immune defect syndrome in Crohn's disease (author's transl)].

In 20 patients suffering for several years from serious chronic relapsing Crohn's disease the following immunological tests were carried out: (1) in-vitro stimulation of blood lymphocytes by PHA-P, (2) identification of T and B cells by formation of spontaneous rosettes and complement receptor rosettes, (3) effect of Crohn's serum on mixed lymphocyte reaction (MLR) of normal allogeneic lymphocytes, (4) in-vitro phagocytosis and intracellular killing of E. coli by polymorphonuclear granulocytes. The results indicate an immune defect of lymphocyte function and the effect of humoral factor(s) on T cell mediated immune reactions: (1) Lymphocyte stimulation by PHA-P was reduced significantly in Crohn's disease. In PHA-P dose response, maximal stimulation has shown a decrease and a shift to higher doses. (2) An increase in the absolute number of B cells caused a decrease in the mean percentage of T cells. The absolute number of T cells did not differ significantly from those of the controls. (3) Crohn's serum has shown an inhibitory effect in MLR of normal lymphocytes. (4) No impairment of phagocytosis or intracellular killing by polymorphonuclear granulocytes has been observed. The results suggest a symptomatic immune defect syndrome in a wasting disease. There is no evidence of a primary immune defect in Crohn's disease.

[Surgical treatment in premalignant lesions of the breast (author's transl)].

Established predisposition to developing of breast cancer is indicative of subcutaneous mastectomy. Subcutaneous mastectomy means a radical biopsy. Histological examination produces the best result by excluding a possible breast cancer in premalignant lesions. When a malignant tumour has been detected the operation can easily be extended to a more radical procedure (Halsted mastectomy). Subcutaneous mastectomy means a radical procedure of treating breast cancer--even with optimal cosmetic results. Early complications are rare, the late results are excellent.

Lesions after sphincterotomy.

Within the last years 70 transduodenal sphincterotomies at stringent indication have been carried out at the Department of Surgery of the RWTH Aachen. This means 9.2% of all operations caused by cholelithiasis. The lethality was 4.2%. The following postoperative complications where stated: a) the bleeding from the divided duct of sphincter with or without haemobile (1.4%), b) the post-sphincterotomy pancreatitis (9.5%) owing to lesion of the pancreatic duct, c) the retroperitoneal abscess with biliary peritonitis (1.8%), d) insufficiency of the duodenal wall or duodenal fistula (1.9%), e) postoperative disturbances of passage of the transsected sphincter Oddi. The haemorrhagic necrosing pancreatitis, the insufficiency of the duodenal wall, the retroperitoneal abscess and the bleeding postsphincterotomy force us to immediate re-operation, while functional disturbances like a spasm or an oedema are controllable pharmacologically and functionally for a short time.

Complications following cava catheterization.

The employment of cava catheterization in intensive care and emergency-treatment has dramatically increased. On the basis of our patients in the Surgical Clinics of the RWTH Aachen risks and complications of the central venous catheterization are explained. Six hundred and eighty-four cases have been examined--categorized according to the method of insertion and according to the technique. In a small randomized study, 60 cava catheters were individually examined bacteriologically.
