Olympus reviewed the following literature article: "three-dimensional versus conventional two-dimensional laparoscopic colectomy for colon cancer: a 3-year follow-up study" by yi-wen yang, et al. background: three-dimensional (3d) laparoscopy was developed to overcome the drawbacks of two-dimensional (2d) laparoscopy, namely lack of depth perception.However, the benefit of 3d laparoscopy in colorectal surgery is inconclusive.Here, we compare the 3-year follow-up outcomes of 3d and 2d laparoscopic colectomy.Patients and methods: a total of 91 consecutive patients who underwent either 3d or 2d laparoscopy colectomy from october 2015 to november 2017 by a single surgical team for colon cancer were enrolled.Data were collected from a prospectively constructed database, including clinico-pathological features and operative parameters.The pathological results, recurrence, survival and systemic treatment were collected from the taiwan cancer database.Results: there were 47 patients in the 3d group and 44 in the 2d group.There were no significant differences in characteristics of patients, operation data, pathological results, complications, operative time, blood loss or the number of lymph node harvested between the two groups.In addition, disease-free survival and overall survival were equal between the two groups.Conclusions: this is the first long-term result of a 3d laparoscopic colectomy.In our 3-year follow-up, there was no difference in long-term outcomes between 2d and 3d laparoscopy for colorectal surgery in an experienced centre.The authors used endoeye flex 2d and endoeye flex 3d laparoscope and reported the following: adverse events: 2d scope: ileus n = 2, chyle leak n = 1, wound infection n = 1.3d scope: anastomosis leakage, n=1.Ileus, n = 4.Adhesion obstruction, n = 2.Chyle leak, n = 2.This article includes 2 reports as follows: (b)(6): ltf-s300-10-3d.(b)(6): ltf-s190-10.This is report 1 of 2 for (b)(6): ltf-s300-10-3d.
