ABSTRACT

It is well recognized that obesity contributes to multiple co-morbidities, and it would seem intuitive that obese patients experience an increase in post-operative complications after colorectal surgery. Overall, the data examining postoperative morbidity and mortality in the obese colorectal patient is inconsistent. Studies have shown a trend for obese patients have a higher post-operative risk of pulmonary embolism, atelectasis, cardiac complications, and thromboembolic disease. However, even with multiple large trials concluding this, there are also many studies showing no difference. The literature has shown that using laparoscopic techniques is safe and feasible, but there is a higher rate of conversion to open, and longer operative times. In addition, obese patients might have a higher leak rate for distal anastomosis as compared with normal weight patients. These patients also have a higher post-operative rate of stomal complications and fascial dehiscense. In reviewing the literature, at best, the complication rate in obese patients is the same as non-obese patients after colorectal surgery, but there are significant trends that suggest a negative effect of obesity after colorectal surgery.
