What … for? (Indications)
Implants in the region of the digestive tract serve to repair and restore e. g. the continuity of the gastrointestinal tract (esophageal, biliary, pancreatic, duodenal, colo-rectal).
They help for abdominal wall reconstruction and the gastroesophageal Reflux Disease (GERD), accidental bowel leakage (fecal or bowel incontinence) and hernia repair.
Depending from underlying disease.
- behavioral: Missing, low compliance
- medical: Infectious diseases, comorbidities precluding the expected benefit, frailty, procedure specific impediments, low life expectancy
- during surgery: Unexpected grade of disease.
- during surgery: Impracticability (e.g. inability to pass through), problems with general anesthesia, death.
- short term: Wound infection, no benefit.
- long term: Chronic infection, rejection of the implant, no benefit.
- restrictions: Depending from underlying disease, control regiment.
