Laparoscopic surgery is performed using thin instruments which are passed through small cuts. In addition, a larger incision (approximately 4 to 7cm) is required to remove the piece of bowel. Occasionally, an operation will have to be converted from a laparoscopic, to a traditional open technique but generally this happens in only 10% of patients.
Anaesthetic techniques have changed so that there are fewer side effects from the anaesthetic agents and patients recover more quickly. In addition, sometimes a fine tube may be placed into the back, known as an epidural catheter, which provides pain relief. The epidural can be continued after the operation so that patients may walk around the ward with minimal discomfort.
