PURPOSE: To confirm the safety and feasibility of single-incision laparoscopic surgery (SILS) and to compare the patient outcomes of single-incision laparoscopic surgery for laparoscopic appendectomy (SILS-LA) performed by resident doctors vs. staff surgeons. METHODS: We performed a retrospective analysis of patients who underwent SILS between May, 2009 and May, 2015 at Osaka Police Hospital. RESULTS: We analyzed 2172 patients. The operations performed consisted of cholecystectomy (n = 598), appendectomy (n = 202), inguinal hernia repair (n = 301), colorectal surgery (n = 673), and gastrectomy (n = 398). SILS was performed safely for a wide range of procedures with acceptable conversion and perioperative complication rates. The resident doctors in our department operated safely on 77 % (156/202) of patients undergoing SILS-LA. The staff surgeons operated on more elderly patients and patients with complicated appendicitis than did the resident doctors. The operative outcomes of the resident-performed SILS-LAs were better than those of the staff surgeons, although there was a patient selection bias. CONCLUSIONS: SILS seems safe and feasible for a wide range of procedures. Based on our findings, we believe that SILS-LA could be a useful teaching procedure for resident doctors to perform on selected patients, under the guidance of an experienced staff surgeon.
