Implications of late complications from adhesions for preoperative informed consent

Abstract

Summary The process of informed consent is a critical aspect of the doctor–patient relationship. Doctors have a professional duty to provide patients with sufficient information if a treatment is associated with a significant risk. NHS guidelines advise doctors to mention risks that occur more frequently than 1–2% or risks that are serious even if the likelihood is very small. In the case of abdominal and pelvic surgery, risks can broadly be divided into early and late complications. Early complications, such as bleeding and infection, have a close temporal relationship with the operation. Such complications are routinely mentioned during the consent process. In contrast, postoperative adhesions cause changes in the normal anatomy that can adversely affect function many years and even decades after the original operation, leaving patients at lifelong risk for late complications. These late adhesive complications, namely bowel obstruction, mechanical female infertility and chronic pain, are often neglected during the consent process. However, the risks to patients from late adhesive complications are serious and well in excess of the accepted threshold where it could be considered a breach in the duty of care not to inform patients. This is reflected by a number of claims against the NHS based on consent issues regarding late adhesive complications of surgery. Therefore, late complications of surgery from adhesions should be included in the pre-operative consent process. This would decrease litigation costs but more importantly also underpins the doctor–patient relationship.
