[Congenital dilatation of the common bile duct. Apropos of l6 cases].

Congenital cystic dilatation of the common bile duct, also known as choledochal cyst, is an uncommon malformation, observed mainly in asiatic children, with a 3:1 female--male ratio. The entity is classified into 4 different types according to the anatomy of the malformation, which effects or not the intrahepatic biliary tree. The authors review theirs experience with 16 consecutive patients with choledochal cyst operated between 1971 and 1985. In 12 children (mean age: 5,8 years, 11 girls) without previous surgery, preoperative diagnosis was made with abdominal ultrasonography and, in some cases, endoscopic retrograde cholangio-wirsungography. Peroperative cholangiography demonstrated a common pancreatico-biliary channel associated with high choledochal amylase content in 6 cases. Surgical treatment consisted in cyst excision with hepatico-jejunostomy in those 12 patients. We also discuss the surgical treatment of 4 previously operated patients with postoperative cholangitis or biliary carcinoma. An anomalous pancreatico-biliary ductal junction (long common channel allowing free pancreatico-biliary reflux) is usually observed in these patients; it is considered to play a role in the etiology of congenital choledochal cysts. Appropriate surgical treatment consists in cyst excision with hepatico-jejunostomy as biliary drainage, in order to eliminate bile stasis, to remove the mechanism which allows continuous pancreatico-biliary reflux and to prevent the occurrence of bile duct carcinoma.

[Hormonally active pancreatic tumors (apudomas). A review].

Hormonally active pancreas tumours have ceased to be rare cases, and by means of up-to-date methods they are now more frequently diagnosed than they used to be in the past. An account, based on the authors' own experience, is given in this paper of diagnostic and surgical problems relating to the various hormone-producing tumours of the pancreas. Particular reference is made to the treatment of malignant apudomata and to new concepts which have resulted from the introduction of H2 receptor blockers.

Surgical principle in total artificial heart--an experimental review.

Based on implantation experiments in calves resulted some experiences for the implantation technic of artificial hearts. After resection of the natural ventricles and of the valvular parts of the aorta and pulmonary artery the connectors should be adapted and implanted. The first connected left ventricle get a caudal-lateral traction especially under supervision of the pulmonary veins and optimal development of the aorta. During connection of the right ventricle it is necessary to check up the inflow - and outflow tract situation. May be, the left ventricle get with this maneuver an unfavourable caudal kinking. Careful preparation and splitting of the pericardium is necessary to avoid obstructions for the venous flow. The closing of the chest and initial changes in position of the animal may alternate good positions of the heart, if the resection as well as preparation, adaptation and bedding don't remarked the discussed principles. One of the most relevant aspects in achieving the consistent survival of an animal undergoing the experimental implantation of a total artificial heart is obviously related to the correct anatomic placement of prosthetic ventricles inside the chest. In this case, the skillful surgical procedures based on an established surgical principle are considered to be attributable in obtaining the optimal hemodynamic situation. Description of the surgical procedures has been made elsewhere. However, it has been difficult to find a well defined surgical principle although particular milestone has already been made by a clinical application of the total artificial heart in 1982. Although the presently available prosthetic ventricles generally fit better in the chest, the problems in design and size of the prosthesis still exist.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary cardiac liposarcoma simulating a left atrial myxoma.

This paper reports the case of cardiac tumor which had been diagnosed as a left atrial myxoma but which later on was identified as being a primary cardiac liposarcoma. The clinical characteristics of cardiac liposarcomas, the problems of differential diagnosis, the prognosis and therapy are reviewed.

[The Rostock artificial heart--current status and perspectives].

The authors report on their experiences gained by animal experiments (calf) and their attempts (human corpses) concerning adaptation of the apparatus to the human thorax. At the present time they do not see a chance for its routine clinical use. The main reason why is the impossibility to install the extrathoracic driving system into the thoracic cage and last not least the wear of the material used for the heart chambers.

[New aspects of peritonitis treatment].

Diffuse peritonitis is a dangerous disease still nowadays. Above all endotoxinemia is responsible for the high lethality. The aim of treatment is to eliminate the source of infection by surgical measures, to drainage and eventually to lavage the peritoneal cavity. Further on parenteral application of antibiotics and sufficient liquid supply are recommended.

[Current surgical management of reflux disease].

This disease has not been fully clarified yet. In our opinion, surgery should only be performed in cases of stage IV because of ulcers, irreversible scar formation, metaplasia of the epithelium, endobrachyoesophagus, stenoses or malignant degeneration. 11 patients suffering from severe reflux oesophagitis (stage IV) underwent a combination of supraselective vagotomy (to lower gastric acidity) fundoplication according to Nissen and intraoperative dilatation of the stenosis or stricture. This procedure was effective. Resection of the cardia is a difficult operation full of possible complications and should be reserved only to cases with malignant degeneration (adenocarcinoma).

[Experiences with the Rostock artificial heart].

A totally artificial heart--the Rostock totally artificial heart (Rostock TAH) was implanted in calves. We can give the following deductions after 27 examinations: -- The Rostock TAH was tested successfully in endurance test about 7 months; it show no sign of wear. -- The surgical technique of the implantation was standardised and a successful experimentation is possible. -- The longest survival time was 15 days. The hemodynamic early results were very good in 3 other animals. -- Modifications of the Rostock TAH were taken up relating to the dimensions of the artificial ventriculi and by mounting a screw cap for avoiding an air embolism. -- Adaption tests in the corpse show that the present form of the artificial heart is not ideal for a possible application in man. -- The problem is still existing in developing a suitable drive system locates intrathoracically. The present drive and control system on a pneumatic base is qualified only for the animal experiment but not for a possible application in man.

[Analysis of the surgical therapy of cardia cancer. Surgical approach, upper resection or gastrectomy, early and late results].

The author has performed radical surgery in 45 patients with carcinoma of the oesophageal gastric junction. The abdominal, abdomino-thoracic and thoracic approach are compared. With regard to later survival, the least favorable results were obtained with the abdominal incision, an approach used in 15 patients, none of them survived 5 years. The abdomino-thoracic incision (25 patients) allowed a good view and enabled radical resection. The 5-year-survival rate in these 25 patients amounted to 16%. The left-side thoracic approach had analogous results.

[Immune level in diffuse peritonitis (author's transl)].

In patients suffering from diffuse peritonitis serum levels of Ig A, Ig M and Ig G were examined. In general, there was no decrease of serum concentration. On the contrary an increase of Ig M and Ig A with a concomitant decrease of the serum albumin level could be observed in the postoperative phase. This happened especially in patients with a lethal outcome. The results obtained do not speak for a severe impairment of the humoral immunity in patients with diffuse peritonitis. Final conclusions concerning the evaluation of an additional gammaglobulin therapy in patients with peritonitis cannot be drawn.
