Objective: Single-incision laparoscopic surgery (SILS) represents the recent advance in laparoscopic surgery claiming to be less invasive than conventional laparoscopic surgery. This study investigates the feasibility and safety of the procedure in colorectal surgery and reports the experiences in our center.
Methods: We retrospectively evaluated 41 consecutive patients surgically treated in our institution (February 2011-April 2013). The patient characteristics were evaluated for: gender, age, body mass index and ASA-score. Data included: indication, procedure, intraoperative complications, operation time, number of lymph nodes, postoperative complications, length of stay (LOS), morbidity and cosmesis.
Results: SILS was performed in 41 patients including 9 patients with colorectal cancer resection. We performed 3 ileocaecal resections, 11 right hemicolectomies, 7 sigmoidectomies and 20 rectosigmoidectomies. The operation time ranged from 45-210 min (median 123 min). Number of lymph nodes identified, ranged from 1-37 (median n=8). Six post-operative complications (14%) occurred: 1 gastroparesis, 1 subobstruction, 1 anastomotic leak and 3 patients needed a blood transfusion postoperatively. Median LOS was 6 days (range 4-21 days). One delayed complication (2,4%) occurred (eventration). None of the patients died. All patients had satisfactory cosmetic results.
Conclusions: With the proviso that the study population was limited in size, SILS is feasible and is a save procedure in colorectal surgery and the procedure has an obvious cosmetic benefit. The results are comparable to other international reports. Still the procedure should be restricted to selected patients and performed by experienced surgeons. Additional prospective studies are essential to define the further benefit.
