Laparoscopic Colorectal Surgery in Patients With Previous Abdominal Surgery: A Single-center Experience and Literature Review.

To present the outcomes of laparoscopic colorectal surgery in colorectal cancer patients with a previous history of abdominal surgery. Data of a total of 121 patients with primary colorectal cancer who underwent laparoscopic surgery were retrospectively analyzed. The patients were divided into 2 groups as those with previous abdominal surgery (PAS, n=34) and those without (non-PAS, n=87). Gastric and colonic surgeries were the most common procedures in the major PAS group, whereas gynecologic and obstetric surgeries and appendectomy were the most common procedures in the minor PAS group. However, there were statistically significant differences in the overall complication rates, wound complications, and anastomotic leaks, although there were no significant differences in the rates of postoperative ileus, pneumonia, port site herniation, and postoperative bleeding between the groups. Our study results suggest that laparoscopic colorectal surgery can be safely performed in patients with colorectal cancer who underwent abdominal surgery previously.
