Laparoscopic versus open appendectomy in children: a prospective randomised study.

43 children between the ages of 7 and 15 years with clinical symptoms of acute appendicitis were randomised to an open appendectomy (OA) or a laparoscopic appendectomy (LA). There were 15 acute cases of appendicitis and 5 perforated appendices in the OA group and 17 acute appendicitis, 3 cases of perforated appendices and 3 other diagnoses in the LA group. The operative time was a little shorter in the OA group. There were no differences in hospital stay or the postoperative course of the patients. In the LA group, there were two minor complications, no other complications were seen. When comparing the two surgical methods in the consistent group of patients with non-perforated acute appendicitis no statistical differences were seen in the operative time, hospital stay or in the recovery of the patients between the OA and the LA groups.We conclude that LA has no significant benefit over OA in routine use. In paediatric patients we recommend an open approach for clinically typical acute appendicitis, but there should be no hesitation to choose laparoscopic approach when the clinical diagnosis is unclear.

Simple ligation vs stump inversion in appendicectomy.

Although modern gastrointestinal surgery has abandoned the invagination of stapler closures, the traditional technique for appendicectomy with appendix stump invagination is still in common use. In a prospective study altogether 200 patients operated on for acute appendicitis were treated either by simple ligation or ligation and inversion of the appendix stump. The complication rates between the two groups were equal. Thus, we recommend the simple ligation technique for conventional as well as for laparoscopic appendicectomy because it is simpler and faster, and it preserves the intact anatomy of the caecal wall.

Autotransfusion of drained blood after total knee arthroplasty.

Osteoarthritic knees were treated by cemented (20 knees) or uncemented (five knees) total knee arthroplasty. The drained blood of the first six postoperative hours was collected, filtered and autotransfused. The blood loss of 20 first postoperative hours averaged 970 ml in the cemented and 1360 ml in the uncemented arthroplasties. An average of 60% of the shed blood was returned to the patients. Transient fever reaction took place during the autotransfusion of three patients, all in the cemented arthroplasty subgroup. No other complications were recorded. The amount of drained blood and transfused blood was compared with a similar series of 16 arthroplasties, treated without autotransfusion. Autotransfusion of filtered blood appears safe and useful in arthroplasty of the knee. Marked reduction of foreign blood transfusion but no direct financial benefit was attained by autotransfusion in these cases. Autotransfusion after uncemented arthroplasty of the knee appears advisable, because of the lack of side-effects, possibly caused by acrylic monomers and because the bleeding (and collection of shed blood) was more extensive than after cemented arthroplasty.
