[Gambee single modified all-layer suture].

Our modified all-layer suture technique allows surgery of colon and rectum with a low rate of anastomotic leaks (2%). In experimental animal research on pigs we compared the modified all-layer suture with the Gambee and the stapling technique. The circulation was examined by radioactive marked microspheres, by microangiograms and by special injection preparations.

[Computer-assisted drug therapy of incomplete ileus].

Auscultation of bowel sounds has a decisive position in management of intestinal paralysis, although personal bound interpretation and documentation may give rise to problems. Our computerized electronic analysis system of bowel sounds permits easy objectivation of auscultation findings. This noninvasive method is optional a repeatable. We investigated 15 patients suffering from intestinal paralysis using this method. Good correlations between clinical findings and the results of our analysis allow reliable estimations of therapeutic measurements. Dosage of drugs influencing peristalsis is facilitated.

[New aspects of surgical therapy of acute gastroduodenal hemorrhage].

The chances for conservative treatment of bleeding ulcers have been expanded by progress in endoscopic haemostasis. Surgery, nowadays, is in many cases applied only to patients with uncontrollable recurrent haemorrhage, after the internist's efforts have failed. This has increased lethality from 20 to 44 percent. To improve results, elective operation is recommended in the no-bleeding interval, following endoscopic haemostasis.

Tumor markers carcinoembryonic antigen, tissue polypeptide antigen, and carbohydrate antigen 19/9 in liver diseases.

The tumor markers carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), and carbohydrate antigen 19/9 (CA19/9) have been compared with regard to their sensitivity to liver diseases. All three markers have been found to be sensitive to liver diseases, but to a different degree: TPA rises the most; CEA the least. The sensitivities of TPA and CA19/9 are higher in a group of liver diseases than, for comparison, in a group of colorectal carcinomas.

The tumor markers CEA, TPA and CA 19-9 in gastric cancer.

In gastric cancer the tumor markers CEA, TPA and CA 19-9 display relatively low sensitivity, which in relation to a specificity of 90% lies between 20% and 25%. Compared with the simple ESR method, these sensitivities are not remarkably greater. But a combination of parameters based on discriminant analysis achieves distinctly greater sensitivities.

[Late results following conservative treatment of elbow dislocations].

Conservative treatment was applied to 56 cases of elbow dislocation in the surgical department of the Hannover School of Medicine, between 1978 and 1986. Follow-up checks were made on 30 of them. Functional results were found to be good to very good in 27 cases. Hence, conservative treatment is considered to be an appropriate therapeutic approach to simple elbow dislocations.

[Computer-assisted analysis of intestinal sounds for assessing the motility of the gastrointestinal tract].

Intestinal noise analysis by means of a computerized analyser is a method by which various functional states of the gastro-intestinal tract can be diagnosed. Interference noise from respiration and cardiac action can be suppressed by filtering. Frequency patterns determined were in good correlation with the clinical picture and auscultation findings. It is, basically, possible to identify the original causative organ.

Comparison of the tumor markers CEA, TPA, and CA 19-9 in colorectal carcinoma.

In 103 patients with colorectal carcinoma carcinogenic antigen, 19-9 (CEA), tissue polypeptide (TPA) and carbohydrate antigen (CA 19-9) were measured in serum. The values determined in these patients and in a control group have been converted into specificity-sensitivity diagrams. Comparison of diagrams of the three markers showed that CEA has the greatest sensitivity in colorectal carcinoma. Different ways to enhance the sensitivity by combination of the markers have been tried. By combination, however, the sensitivity of the single markers is not essentially enhanced.

Neopterin. A tumor marker in colorectal carcinoma?

Neopterin is compared with other tumor markers in colorectal carcinoma. Its sensitivity is clearly lower than that of CEA, TPA and CA 19/9 and is even lower than the sensitivity of the erythrocyte sedimentation rate. The ability of neopterin to discriminate between different tumor stages is also lower than that of the other markers. The discriminant analysis shows that measurement of neopterin in the serum of patients with colorectal carcinoma gives no essential additional information.

[Therapeutic possibilities in adhesions].

Laparotomy was performed on 36 patients with persistent "adhesion complaints". Good therapeutic success was obtained from detachment of omental adhesions on the abdominal wall and of omental cords from the minor pelvis as well as from adhesiolysis in the hypogastric region. No peritoneal adhesions at all were recorded from nine patients, although they had undergone several operations before. Complaints were removed from one third of all patients, while nearly 20 per cent were improved. One death occurred, following exploratory laparotomy, due to stress-induced ulcer perforation. No peritoneal adhesion had been present in that case. No complications at all were experienced with any of the other patients.

[Diagnostic error: incarcerated hernia].

Reported in this paper are 19 patients on whom incarcerated hernia had been pre-operatively diagnosed, which proved to be wrong during the operation. Various types of inflammation, including appendicitis in the hernial sac, as well as accumulation of pus in the hernial sac and abscesses, were the disorders which had led to false diagnosis in ten cases. Tumours were recorded from four patients and cysts in the round ligament of the uterus from another three, while a funicular hydrocele was detected in one patient. In one case, painful swelling through haematoma in the inguinal region had been caused by ruptured aortic aneurysm. Ultrasonographic diagnosis is recommended for all dubious cases. Surgery should be considered a preferable option in situations of lasting uncertain diagnosis, in order to avoid incarceration from remaining unnoticed.
