Comparative Study
[Reconstructive surgery using an artificial dermis (Integra): results with 19 grafts].
Integra was initially developed for covering of acute burn wounds. The artificial dermis is a bilayered dermal substitute, the upper layer is a thin silicone layer, which acts as temporary epidermis, the under layer is a collagen network, which functions as the dermis. In the meantime, Integra is applicated in reconstructive surgery. ⋯ The advantages of using Integra in reconstructive surgery are its immediate availability and the availability in large quantities. Disadvantages are the necessity of two operations, risks of infection, the high price and time-consuming dressing changes. Defect covering with Integra should be used in special cases.

Comparative Study
[Open versus laparoscopic operation for perforated appendicitis--a comparative study].
Laparoscopic therapy of complicated appendicitis is still discussed controversially. This retrospective study compared the clinical results of open and laparoscopic appendectomy in a single centre. ⋯ Laparoscopic appendectomy is a safe procedure for the treatment of complicated appendicitis with a significantly decreased complication rate and shorter postoperative stay.
