Single-Incision Plus One Port Laparoscopic Surgery for Myomectomy: A Retrospective Study

Figures & data

Figure 1. (A, B) The condition of the incision after SILS + 1-M operation and drainage tube extraction was improved. (C) Incision condition after LESS-M operation. (D, F) A two-port entry system with a transumbilical single-port technique and an additional 5-mm trocar was used for the extraction of myomas through the transumbilical single-port site. (E) The myoma was removed and the myometrium incision was sutured. SILS + 1-M: single-incision plus one port laparoscopic myomectomy, LESS-M: laparoendoscopic single-site myomectomy.
