[Cemented bipolar prosthesis in multimorbidity patients with coxarthrosis. Short- and intermediate-term results].

The treatment of coxarthrosis with the cemented Duopleet prosthesis represents an efficient alternative to total hip prosthesis in elderly and polymorbid patients. The early results show a tolerable rate of complications. The patients can be mobilized early. The mortality seems to be low. Medium-term results are satisfactory. The rate of protrusions is lower than in patients with common femoral head prosthesis. Paraarticular ossifications are seen frequently. In numerous patients we found pain with projection to the operated hip.

[Ender nailing versus dynamic hip screw--a comparison of early postoperative results].

Proximal fractures of femur may be alternatively treated by implantation of dynamic hip screws or Ender-nails. Estimation of the value of both measures is to be done by analysis of the early postoperative course. Full load bearing capability was obtained in 83% of all cases with Ender-nails as against 68% of all cases after implantation of hip screws. Duration of operation was clearly shorter and the need for blood transfusions was reduced by implantation of Ender-nails. The amount of specific technical complications was equal in both procedures. There were no differences in the postoperative ability to walk.

[Results of cryosurgery in the treatment of inoperable tumor stenoses of the anus and rectum].

Inoperable tumor stenosis of anus and rectum may be treated surgically only by implantation of artificial anus. Cryosurgery proves to be a feasible alternative in order to maintain free passage of the gut. The cryoprobe is introduced through a rectoscopy under direct view. Visible tumor is touched with the tip of the cryoprobe and subsequently temperature is lowered to approximately -19 degrees C. Usually anesthesia is not required. From 1976 to 1989, 213 patients had been treated by cryosurgery in our department. In 23 cases the use of an artificial anus became inevitable afterwards.

[The value of serum endotoxin determination after gastrointestinal interventions].

Serumendotoxins were measured in 11 patients after gut surgery and compared with healthy people as a standard. In cases of uncomplicated course 3 to 4-fold raised serumendotoxin levels were observed in a typical two-peak pattern. It was not before the fifth day following operation that serum levels declined constantly. In contrast to these findings, patients suffering from septic complications showed a permanently raised endotoxin level, which correlated well with their clinical course. Therefore single peaks of serumendotoxin measured after operation should not be overvalued. Constantly raised levels following operation, however, may indicate some kind of septic complication.

[Insulinoma. Results of surgical treatment].

The insulinoma is the most common pancreas tumour with endocrine activity, with more than 2,000 cases being described in the literature worldwide. The first successful extirpation was performed by Graham in 1928. Clinical appearance is characterized by severe paroxysmal hypoglycaemia together with inadequately increased serum insulin levels. Surgery is indicated in such situations because of limited effectiveness of medicamentous therapy. Surgical approach and long-time results are discussed in this paper, with reference being made to 13 cases of the authors.

The serum activities of AP, gamma-GT, GLDH, GPT and CHE after complete biliary obstruction and choledochocaval fistula in the rat.

The activities in serum of alkaline phosphatase, gamma-glutamyltransferase, glutamate dehydrogenase, glutamic pyruvic transaminase and cholinesterase were compared after complete biliary obstruction (CBO) and choledochocaval fistula (CCF) in the rat. CCF was used as a model of complete biliary retention without bile stasis and without increased pressure in the biliary tract. The increases in AP, GLDH and gamma-GT within 24-h post-op. show no difference between the two experimental groups. The conclusion is that the retention of biliary constituents alone is responsible for the increase in the levels of serum activity and that other conditions like bile stasis and increased pressure in the biliary tract do not play an important role in the pathogenesis of these alterations. The rise of GPT activity in CCF is of a lesser degree than in CBO.

Effect of fasting and transportation on various physiological parameters and meat quality of slaughter hogs.

Forty-nine slaughter hogs were transported and fasted or fasted with no transport for 0 (no transport), 24, 48 and 72 h. Blood samples were taken before treatments were imposed and again prior to slaughter. Soft tissues of the ham were chemically analyzed and loin samples were evaluated by a sensory panel. Fasting and transportation decreased plasma triiodothyronine and hematocrit and increased plasma osmolality. Preslaughter treatment did not affect juiciness or desirability of cooked chops or percentage of fat in the ham soft tissues. These data suggest that although fasting and transporting of slaughter hogs may disrupt homeostasis of pigs, such physiological changes do not negatively affect meat quality.

[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.
