[Contraindications of combined surgical procedures in abdominal surgery (author's transl)]

Combined surgical procedures can often increase the entire trauma of operation. A comparative study of our patients showed, that small additional procedures did not influence the operative stress and had only few contraindications. On the other hand medium sized and greater simultaneous operations caused an increased number of postoperative complications, which to some extent resulted from additional surgery. Among other risk factors the increased rate of postoperative complications should be considered concerning the performance of combined surgical procedures.
