Background: Single-incision laparoscopic surgery (SILS) was introduced to further the enhanced outcome of conventional multiport laparoscopy (CML). We compared their short- and long-term outcomes in colorectal surgery. Materials and Methods: Retrospective review of patients who underwent elective laparoscopic colorectal surgery during 3-year period. Patients' data, surgery outcomes, and oncological results were compared. Results: Sixty-one patients (33 male, 28 female), mean age 67.4 years, underwent laparoscopic colonic resections: 28 SILS and 33 CML. Twenty-three (37.7%) patients had previous abdominal surgery. There were 19 (31.2%) right, 9 (14.7%) left, and 2 (3.3%) total colectomies, 16 (26.2%) sigmoidectomies, 13 (21.3%) anterior and 2 (3.3%) abdominoperineal resections. Colonic malignancy was a main indication for the surgery in 51 (83.6%) patients. Mean surgery time and postoperative stay were 92.0 minutes and 9 days, respectively. Pathological examination revealed stage I colon cancer in 16 (32%), stage II in 22 (44%), stage III in 10 (20%), and stage IV in 2 (4%) patients. Mean number of retrieved lymph nodes was 19 ± 13.5. No differences were found between groups in demographic data, type of surgery, surgery time and hospital stay, pathological results and tumor staging, and disease-free and overall survivals. In the SILS group, placement of additional trocar was required in 7 (25%) and conversion in 3 (10.7%) cases compared with 1 (3%) case of conversion to formal laparotomy in the CML group. Overall postoperative morbidity was 16.4%. There was no mortality in both the groups. During the study period, 3 patients from the CML group had cancer recurrence. Conclusions: SILS is a feasible and safe technique compared with CML in terms of surgical and oncological outcomes.
