Comparison of suture materials for intestinal anastomosis.

Ninety end-to-end entero-anastomoses were prepared in 45 dogs by inverted single row knotted sutures. Half of the anastomoses were carried out on the small intestine, the other half on the colon. Of the two non-absorbable materials that of the polyester type proved to be the best. Of the absorbable materials Dexon can be recommended for intestinal anastomoses, but on the colon Dexon is not reliable. Plain catgut is not recommended for this kind of anastomoses.

Experimental heterotopic pancreas segment transplantation.

Autologous and allogenic transplantations of the caudal part of the pancreas into the omentum and the spleen were performed in 18 dogs. The fate of the transplants was followed histologically. In the grafts the Langerhans-islands preserved their integrity longer than in the other parts of the organ, but in 4 to 6 weeks they, too, necrotised.

[Experimental pancreas transplantation in swine].

After surveying the problem of pancreas transplantation the results of pancreatico-duodenal transplantation attempts performed on dogs and 20 pigs are reported. Surgically, the major pancreatic duct is anastomosed to a Roux' loop using a preserved duodenal patch around the papilla. The graft is sited unto the retroperitoneal space. The animals survived for 6 to 9 months. In some cases an increasing fibrosis of the transplantate was observed. Most often, the animals died from pneumonia. The authors want to continue their research in order to obtain better results.

Treatment with oxidized cellulose of the resection surface of the lung.

Segment resection was performed in 15 dogs. The resected surface was covered with absorbable cellulose bioplast (Surgicel)R and fixed by the tissue adhesive Histoacryl-N-Blau. The results were checked by gross and microscopic examinations which showed that the gradually absorbed material had been replaced by a layer of connective tissue. The method is recommended for use in human operations.

Application of cubital venous graft for double coronary bypass.

In experiments with cadaver hearts the cubital vein was used for aortocoronary bypass anastomosis. The indications, advantages and drawbacks of the use of a venous section of inverted Y shape are discussed. Since 20 to 30% of patients in need of an operation of this type have saphenous veins which cannot be applied as grafts, use of the cubital vein is recommended.

Experimental anastomosis of small vessels with plastic tubing.

Forty experimental anastomoses have been prepared with the help of polyethylene tubes on the hearts of 10 human corpes, 2 pigs and 16 dogs. In dogs the left internal mammary artery was anastomized with one of the coronary branches of the moving heart without extracorporal circulation. The plastic tube was moved in the vessel by means of a thread attached to the end of the tube and the tube was retrieved by the same thread before the closure of one of the suture lines. The method is illustrated on schemiatic diagrams and its advantages are pointed out.

[Management of experimental heart injuries].

Treatment of 28 stabbed heart wounds in 15 dogs was done with traditional suturing or by means of an adhesive and Surgicel. The combination of Surgicel with adhesive ensured adequate closure of the wound and healing. The method is recommended for the treatment of human heart injuries in certain cases.
