Single-Incision Two-Port Laparoscopic Surgery as A Substitute for Single-Port Trans-umbilical Laparoscopic Surgery: Patients who Underwent Laparoscopic Appendectomy Surgery

Laparoscopic management of diseases has now been accepted as a golden standard in international societies. However, there are still many studies on the newest methods of minimally invasive surgery in order to achieve the best surgical procedure with the most favorable perative outcomes of single-port trans-umbilical laparoscopic appendectomy and single-incision two-port laparoscopic appendectomy. In this retrospective study, 77 patients participated who underwent single-port trans-umbilical laparoscopic appendectomy and single-incision two-port laparoscopic appendectomy during one year (May 2017-2018). In single-incision two-port laparoscopic appendectomy group, two 5-mm trocars were implanted in a trans-umbilically, and another hole was used for left-hand instruments. Demographic specifications, operation data, and post-operative results of groups were compared using Chi-squared test or, if necessary, Fisher test. The T-test was used to compare the average of the two target groups that were independent of each other. The significance level of the tests was considered to be 0.05. Statistical analyses were performed using the SAS EG 5.1 server, version 9.3. (SAS Institute Inc., Cary, NC, USA) The total average time of single-incision two-port laparoscopic appendectomy surgery was significantly lower than that of single-port trans-umbilical laparoscopic appendectomy (P = 0.003). The average laparoscopic time was significantly lower in the single-incision two-port laparoscopic appendectomy group (P < 0.001). The average number of postoperative analgesic drugs in the
single-incision two-port laparoscopic appendectomy group was significantly lower than that of single-port trans-umbilical laparoscopic appendectomy (p = 0.002). The average number of hospitalization  post-operative days in the single-incision two-port laparoscopic appendectomy was significantly lower than that of single-port trans-umbilical laparoscopic appendectomy group (P = 0.008). No other statistically significant difference was observed between the two groups. According to the findings of this study, the average number of duration of the single-incision two-port laparoscopic appendectomy was significantly lesser and thus required less pain management; also, in aesthetic point of view, its result was similar to that of single-port trans-umbilical laparoscopic appendectomy.
