Abstract
Obesity and, particularly, visceral fat are associated with increased risk of colorectal cancer incidence; furthermore, in the surgeon’s opinion, obesity is commonly related to higher technical difficulties and postoperative complications.
Technical problems in colorectal surgery are specially linked to a difficult exposure and vision of the pelvic and perineal site, with consequent impaired maneuvers of instruments in a restricted working area. Longer operative times and increased rate of conversions are described, but data on outcomes in obese patients are sometimes lacking or controversial. Results on supposed higher postoperative complications are difficult to evaluate: literature data on colon and rectal operations as well as different extent of obesity are often mixed.
Use of appropriate pelvic retractors in open surgery is mandatory. Laparoscopic surgery can lead to important benefits, but it is technically demanding and requires a highly standardized technique and specific surgical instruments, in order to decrease intraoperative difficulties and improve outcomes.
