title: Transumbilical single port laparoscopic appendectomy using basic equipment: a comparison with the three ports method.
abstract: OBJECTIVE
  Single port laparoscopic surgery is a rapidly evolving laparoscopic surgical approach. We report a comparison of transumbilical single port laparoscopic appendectomy (TUSPLA) and conventional laparoscopic appendectomy (CLA) in a Korean military hospital.
  
  
  METHODS
  This single-center retrospective study of 63 patients who received laparoscopic appendectomy was conducted between May 2011 and October 2011. Nineteen patients received TUSPLA and 44 patients received CLA. Clinical outcomes such as operation time, hospital stay, postoperative pain, diet, and postoperative complication were reviewed.
  
  
  RESULTS
  There were no statistically significant differences between TUSPLA and CLA patients, respectively, in operation time (58.9 minutes vs. 52.3 minutes, P = 0.262), duration of hospitalization (10.2 days vs. 10.6 days, P = 0.782), mean visual analogue scale score (2.6 vs. 2.5, P = 0.894), and return to diet (1.6 days vs. 1.7 days, P = 0.776). There were two cases (10.5%) of short-term complications in the TUSPLA group and four cases (9.1%) of short-term complications in the CLA group. All patients were fully recovered at discharge.
  
  
  CONCLUSIONS
  TUSPLA is a feasible alternative for CLA. When a glove port is used, no special instruments are needed. Thus, it can be performed in a hospital equipped with basic laparoscopic surgical instruments.
