Impact of minimally invasive techniques in colorectal surgery.

Minimally invasive techniques have had a marked impact on colorectal surgery despite the limited adoption of such techniques. Patients stay in the hospital a shorter time, experience less pain, and have less chance of developing a wound infection, an incisional hernia, a bowel obstruction, or difficulty becoming pregnant. Training courses have undergone metamorphosis from ad hoc animate courses to highly defined educational opportunities, and fellowships have had to respond to the educational demands of trainees demanding to be exposed to minimally invasive techniques.
