Single-Incision, Two-Port Laparoscopic Appendectomy as an Alternative to Transumbilical Single-Port Laparoscopic Appendectomy.

PURPOSE

We designed a modified technique to perform an advanced procedure using conventional instruments and did not employ specialized single-incision laparoscopic surgery (SILS) port equipment. We compared postoperative results for transumbilical, single-port laparoscopic appendectomy (TUSPLA) and single-incision, 2-port laparoscopic appendectomy (SITPLA).

METHODS

This retrospective study enrolled 77 patients who underwent TUSPLA or SITPLA to provide more minimally invasive surgery between May 2017 and April 2018. TUSPLA was performed in 39 patients and 38 underwent SITPLA. In the SITPLA group, two 5-mm trocars were inserted through the umbilicus and an extra puncture site was used for a left-handed instrument. Demographic characteristics, operative data, and postoperative outcomes were collected and compared between the groups.

RESULTS

The mean total operative time in the SITPLA group was shorter than in the TUSPLA group (=0.003). The mean laparoscopic instrumental time was also shorter (<0.001) in the SITPLA. The number of postoperative analgesics in the SITPLA group was less than in the TUSPLA group (=0.002). The length of hospital day after surgery was shorter in the SITPLA group than in the TUSPLA group (=0.008). There were no other significant differences between the groups.

CONCLUSION

SITPLA had a shorter operative time, required less pain management, and had a similar cosmetic outcome when compared with TUSPLA.
