[Chronic diseases after gastrointestinal surgery].

Gastrointestinal surgery may not only lead to early postoperative complications but also chronic consequences. These have therapeutic implications for affected patients. The kind and extent of surgical intervention determines the spectrum of postsurgical phenomena which may occur. These chronic consequences are due to changes in gastrointestinal anatomy, the synchronization of digestive processes, or the ability to digest and absorb food. In case of transplantation surgery, adverse effects of immunosuppression have to be considered. Sometimes, chronic consequences of surgical procedures are difficult to recognize. The knowledge of typical problems associated with gastrointestinal surgery is necessary to enable early and timely diagnosis and treatment. Some negative effects can be avoided by early therapeutic interventions. This article summarizes typical chronic consequences of gastrointestinal surgery.
