[Initial experiences with laparoscopic cholecystectomy].

Laparoscopic cholecystectomy was performed in 45 patients for treatment of symptomatic gallbladder disease. The age distribution was 23 to 79 years. In four patients the procedure was not completed and a laparotomy was performed to remove the gallbladder: once because of a defective instrument, once because of bleeding of an omental adhesion and twice because of disturbed anatomy of the cystic duct region by inflammatory tissue. In four cases a laparoscopic cholecystectomy was performed because of an acute cholecystitis and in three cases a laparoscopic cholecystectomy à froid was performed. There were three postoperative complications: one case of bleeding and two cases of leakage of bile during five and ten days, respectively. In all these cases the treatment was conservative and laparotomy was not necessary. The postoperative hospital stay varied between 3 and 11 days with a mean of 4.2 days. The period of unfitness for work after leaving hospital ranged from one to three weeks. If for whatever reason the laparoscopic procedure cannot be completed, a laparotomy to remove the gallbladder should be performed in the same session. Laparoscopic cholecystectomy is a new, safe, less invasive method to remove the gallbladder with significant benefit to the patient. The morbidity is low and the hospital stay is short. A considerable reduction of costs is achieved with this treatment.

Percutaneous transluminal dilatation of the iliac artery: long-term results.

One hundred fifty-four patients with stenosis of the iliac artery underwent percutaneous transluminal angioplasty (PTA). These patients were followed for 1-7 years. The long-term results of the PTAs were analyzed by computer, and life tables were generated for dilatations of the iliac arteries with unimpaired flow and for those with an obstruction in the outflow tract. The accumulative 7-year patency rate was 90%, which agrees with other reports. This study demonstrates that the long-term results of PTA of iliac arterial stenoses are competitive with reconstructive vascular surgery. PTA should be the treatment of choice in patients with iliac arterial stenoses.

Percutaneous transluminal angioplasty of the femoropopliteal artery: initial and long-term results.

Patients with dilated stenoses and recanalized occlusions were evaluated to assess the initial and long-term results of percutaneous transluminal angioplasty (PTA) in the femoropopliteal artery. The follow-up period was at least 1 year. The initial success rate was 84% (128/164). The initial results were influenced by the radiologist's experience, catheter selection, and type of lesion. The 5- and 7-year cumulative patency rates were 70% and 60%. There was no difference in long-term patency between initially successful stenoses and short (less than 3 cm) occlusions. Both the morphology and location of the stenotic lesion influenced the long-term results. Although many factors influence the initial and long-term success rate, results of this study justify PTA in the femoropopliteal artery. Patients with localized stenoses and short occlusions are best suited for this treatment.
