[Postgastrectomy syndromes with special reference to reflux esophagitis].

60 patients without suspicion of recurrence of stomach cancer have had a follow-up by mean of 65 months after the procedure of a total gastrectomy. In 16 cases an additional esophagomanometric and endoscopic-bioptic examination was performed. Up to 1975 the operative procedure of stomach replacement was a jejunal interposition, afterwards the technique of a jejunoplicationn. Clinical signs of an esophageal reflux were found in one half of the patients with a jejunoplicatio and in a third of the cases with a jejunal interposition. Endoscopic-bioptic evidence of a reflux-esophagitis has been found in 13 of 16 patients. A functioning sphincter mechanism of the lower esophagus could be demonstrated in 5 of 16 cases. There was no proof of a correlation between the results of endoscopic-bioptic and manometric examinations. A prevention or reduction of esophageal reflux is as well possible by the technique of jejunal interposition as by jejunoplication.

[The trace-element zinc in medial fractures of the collum femoris and in coxarthrosis (author's transl)].

In a comparative study among two groups of patients--persons with a medial fracture of the collum femoris and persons with advanced coxarthrosis--the zinc-content of the femur was measured. For this analysis a bone-biopsy was performed when an endoprothesis was implanted. In some of the patients the zinc-levels in the blood were determined on several occasions. If the zinc-content of the blood was low, similarly the zinc-content of the bone was reduced, especially in patients with medial fractures. In patients with severe coxarthrosis the zinc-content is reduced by 50%.

[Subclavian-carotid transposition in the treatment of obstructive subclavian disease with steal syndrome].

Eleven patients with subclavian steal syndrome underwent end-to-side transposition of the subclavian into the common carotid artery. The post-operative evaluation was done in every case by neurological examination, brachial blood pressure measurement, transcutaneous Doppler examination and by angiography. The operative result of this reconstruction, which was performed mainly on high-risk patients, was excellent. The symptoms of subclavian steal disappeared. In all but one patient the brachial pressure raised to normal. After transposition a blood flow reduction of 20% was measured intraoperatively in the peripheral common carotid artery, while the vertebral blood flow reversed to its natural direction. The peripheral common carotid artery pressure measured simultaneously remained unchanged, and hemodynamic criteria of carotis steal were not detected. The blood flow quality at the anastomosis was measured by the turbulence index in patients with an ideal reconstruction. The amount of blood flow distortion caused by the anastomosis was negligible. Therefore a long patency is expected. In patients with occlusive disease of the proximal subclavian artery we like to recommend the transposition as the procedure of choice, because the method uses one single incision for the extrathoracic exposure and one anastomosis-only without any graft material.

[Treatment of late occlusions and stenoses after an aortofemoral bypass operation].

Thirty-three patients with one or several late occlusions in 43 limbs of aortofemoral dacron grafts underwent 56 reconstructions because of impending limb loss. Thrombectomy alone with patch closure was less successful. Excision of the femoral anastomosis, resection of the distal part of the occluded prosthetic limb and replacement by a new velours graft tube together with profundaplasty and further downstream reconstruction revealed the best results. The early reocclusion rate was 10%, the late reocclusion rate was 10%. There was no operative mortality and no amputation. Two late deaths occurred, in one case due to grade III infection with sepsis. Another late graft infection was successfully managed by an extraanatomic bypass and excision of the infected limb. The reasons for late occlusions of aortofemoral grafts were found to be incomplete reconstruction of the outflow tract, technical failure at the time of primary reconstruction and progressive atherosclerosis. Hypertonus was common in all cases with progression of the disease. Technical details of the operative management for late occlusion are presented.

[Blood rheology in chronic arterial occlusive disease as influenced by vasodilators (author's transl)].

Increased blood and plasma viscosity was found in patients with chronic arterial occlusion in comparison with healthy probands. The measurements were done at high and low shear rates. Parenteral pentoxifylline (Trental) lowered blood and plasma viscosity of patients significantly, especially when measured at low shear rates. Application of bencyclane (Fludilat) produced variable results. A definite connection between rheological changes and alterations of the protein fractions in plasma could not be established.
