[Percutaneous drainage of abdominal abscesses. I. Technic and results].

88 intraabdominal abscesses in 77 patients were treated by percutaneous drainage. Patients were cured in 63 percent. Complications were observed in 11 percent followed by surgery in two instances. Ten out of 75 patients (13 percent) died in the postprocedural course from multiple organ failure or postoperative complications. A fatal outcome, however, was never attributable to the percutaneous procedure. Technical considerations of percutaneous abscess drainage are described in detail. Its similarities with open drainage and advantages over septic surgery are discussed.

[Percutaneous drainage of abdominal abscesses. II. Value in comparison with septic surgery].

Based on the review of the literature and experience with own cases the current status of the therapy of abdominal abscesses by percutaneous catheter drainage is described. Indications, reasons for failure, complications, and mortality are presented in detail. Compared with surgery percutaneous abscess drainage (PAD) seems to have better results; however, this statement should be viewed with caution since the input of modern imaging techniques might have improved current surgical success rates. A trial of PAD can be recommended in all feasible cases because it offers high curability with little morbidity.

[Non-operative percutaneous cholecystostomy in acute postoperative cholecystitis].

Seriously ill patients with acute postoperative cholecystitis are at high risk from emergency cholecystectomy. A case is presented which shows that non-operative percutaneous cholecystostomy may improve the patient's condition. With continuous percutaneous drainage of the infected bile and selective antibiotic treatment, the patient's condition can be stabilized so that all the necessary preparations for elective cholecystectomy can be made.

[Removal of retained bile duct stones through the T-tube drain].

Within seven years 23 patients were treated postoperatively by percutaneous bile stone extraction. This procedure was successful in 18 patients. Although an interval of 5-7 weeks between choledochotomy and percutaneous extraction is recommended, the procedure was done 11 to 31 days after surgery with no negative effects. In six cases the stones had to be dislodged into a more favorable position with a Fogarty-type balloon catheter. The papilla of Vater was dilated in two cases. With the development of newer techniques trans-T-tube extraction remains the treatment of choice in retained intra- and extrahepatic bile duct stones.

[Self-retaining loop catheter for percutaneous bile duct drainage].

A percutaneous catheter which can be looped by means of a nylon thread was used in 32 patients for percutaneous biliary drainage. The catheter can be fixed in this way and is thereby prevented from migrating from the biliary system. The catheter is not suitable for proximal obstructions. Problems may arise during the removal of the nylon thread and loss of looping of the point of catheter.

[Results of percutaneous abscess drainage].

Between 1978 and 1983 fifty-two abdominal abscesses in 44 patients were drained percutaneously. 79% of the abscesses occurred as postoperative complications. The overall success rate was 60%, whereas only 42% of left subphrenic abscesses were cured. Complications were encountered in 4.5%. Reasons for drainage failures were: liver sequestration, loculation, fistulae and recurrences. Percutaneous abscess drainage is an alternative, and valuable addition, to surgery.

[Diagnosis and therapy of fibular ligament injuries in the ankle joint in children].

Turn fibular ligaments of the ankle go often undetected when not accompanied by osseous lesions. The significance of injuries to the major supporting ligaments of the ankle is underestimated in children. Next to the clinical findings stress radiographs of the ankle joint in two projections are mandatory. Measurements of anterior and lateral displacement under stress and displacement index need to be compared with the healthy ankle. Diagnosis of a fibular ligament rupture is based on clinical findings and on differences between the measurement results (injured compared to healthy) by way of three different techniques. Rupture of a fibular ligament is an absolute indication for surgery--even in children.

Extrabiliary obstructive jaundice.

Extrabiliary obstructive jaundice is only encountered in biliary digestive anastomosis when the draining bowel itself is obstructed. In two patients, the cause of obstruction was a local tumour recurrence.

[Lipohaemarthrosis (author's transl)].

Besides the presence of blood in an injured joint, fat-containing blood can also be found in the joint with intra-articular fractures. This condition, which can be demonstrated by x-ray film, is known as lipohaemarthrosis. We found this to be the case in 8 out of 295 patients with shoulder dislocation. The origin, significance and differential diagnosis of this condition are described.

[Treatment of pains from bone metastases with 90Y (author's transl)].

For palliation of pain caused by bone metastases beta radiation isotope therapy was successful. As shown in experimental work on animals bone uptake of 90Y with its shorter half-life is high when it is administered as a citrate complex. 90Y can be eluted with high purity from a 90Sr "cow". The retention in man was found by whole-body counting to be higher than 80%. In preliminary trials on 16 patients the analgetic effect was the same as that of 89Sr. The properties of 90Y therapy are discussed.
