[Postoperative syndromes after portacaval shunt in patients with cirrhosis of the liver (author's transl)].

Postoperative care of patients with a portacaval shunt is identical with the perioperative care performed to avoid the dangerous complications of cirrhosis of the liver. Clinical symptoms (edema, ascites, skin changes) and clinical chemistry (prothrombin time, bilirubin, albumin) will allow, to survey liver function appropriately. Neurological examination and simple psychosomatic tests (test of writing, trail making test) will allow to recognize early the occurrence of hepatoportal encephalopathy. EEG examinations done every 4 to 6 months are helpful in diagnosis. X-ray or endoscopic examinations should be done, if gastric ulcers are suspected. A definite warning must be pronounced against using high ceiling diuretics of unnecessarily; diuretics should be given only for short periods of time and in low dosage. Regular measurements of serum electrolytes are mandatory. The patient must be informed about the rationale of the diet restricted in proteins and abstinence from alcohol.

[Recurrent ulcer after stomach resection--its operative therapy with reference to etiology and pathogenesis].

Over a period of 12 years, 100 patients with a confirmed ulcer recurrence after prior gastric resection underwent a standardized surgical procedure. The mortality rate of the electively operated patients amounted to 1 per cent. The follow-up examination yielded satisfactory surgical results in over 80 per cent of the patients treated in this way. We consider the exclusively abdominal procedure suitable in cases of recurrent ulcer in order to ensure adequate diagnosis and therapy.

[Benign tumors in the upper gastrointestinal tract (author's transl)].

Information is given on 113 cases of solitary or multiple benign tumors of the upper gastrointestinal tract. The clinical symptoms and procedures of diagnosis of these rare tumors of esophagus, stomach, and small intestine are discussed. For therapy, surgical intervention is usually required because of malignant degeneration and complications like bleeding or perforation. Mortality was found to be 4.4%, so that the individual indication for operation should be considered.

[Surgical therapy of advanced gastric cancer (author's transl)].

Aggressive approach has been recommended for the treatment of gastric cancer. Therefore, it is justified to carry out total gastrectomy or upper gastric resection as an ultimate palliation in advanced gastric cancer. 214 patients with advanced gastric cancer have undergone such a palliative treatment. The results of these patients, including operative mortality, survival rate and quality of life, will be compared with the results of those patients who underwent other kinds of palliation such as gastroenterostomy, oesophageal intubation, Witzel fistula. A special designed spiral tuber for the treatment of stenosed and inoperable cardiac and oesophageal carcinoma will be described.

[Indwelling venous catheters. Results of a clinical and experimental study].

Six venous indwelling cannulas were observed under constant frame conditions (low osmolar solutions, constant infusion solution, prospective randomized study). There is a close correlation between the complication rate in the vein and quality of the material and puncture. The best results were achieved with Teflon cannulas. Here the condition of the transitional zone between mandrin and synthetic material was of special importance as well as the fact that the form stability also had to be guaranteed after application. The thrombotic dry weights of these cannulas, determined in animal experiments, yielded low values for polytetrafluorethylene (PTFE) or polyethylene (PE), but PTFE and PE cannulas have led to an increase of the thrombotic dry weight in 24 and 48 h of indwelling time.

[Intraoperative open transluminal angioplasty (IOTA)].

Percutaneous transluminal angioplasty (PTA), is a nonsurgical method of treating atherosclerotic ischaemic peripheral vascular disease. This paper describes the technique of intra-operative open transluminal angioplasty (IOTA) as an adjuvant therapy during vascular surgery. The main advantage is the shorter duration of surgical procedures. The procedure is simple and preliminary results are favourable, particularly in elderly patients or in patients reduced physical state. The initial impression of its effectiveness together with the low incidence of complications offers a new dimension for the preservation of the leg, especially in stage III and IV, in unfavourable cases such as recurrent stenosis, insufficient run-in or run-off and acute distal infection of the leg.

[Experimental liver arterialization following portacaval shunt - rehabilitation].

Comparative investigations were carried out on rats with healthy livers and rats with thioacetamide-cirrhotic livers on postoperative days 2 and 21 following end-to-side portacaval anastomosis alone and with additional (documented) flow-limited arterialization of the portal stump. After portacaval anastomosis alone, all the parameters investigated (biochemical, pharmacokinetic, and morphological) were impaired. By means of the additional flow-limited arterialization, the disadvantages can be greatly headed off, more clearly in healthy than in cirrhotic animals.

[Factors influencing anastomotic leakage after total gastrectomy with special reference to ABO blood groups (author's transl)].

One of the hazardous problems of total gastrectomy is anastomotic leakage. A retrospective study was carried out to evaluate the factors which may have an impact on anastomotic leakage. 188 patients who underwent total gastrectomy at the Surgical Department in the Klinikum Steglitz of the Free University of West-Berlin and the Marien-Hospital in Osnabrueck from 1963 to 1979 were investigated. Age, sex preoperative haemoglobin and total protein as well as the dignity of the underlying disease have been found to have no influence on the rate of anastomotic leakage. However, patients with blood group A have a significantly (p less than 0.05) lower leakage rate than patients with blood group 0, and patients with scirrhous carcinoma have also a significantly lower leakage rate than those with adenocarcinoma and solid carcinoma. Possible relationship among ABO blood groups and different kinds of disease are discussed.
