  Laparoendoscopic single-site surgery (LESS) has emerged as a minimally invasive surgery in the last few decades. As instruments are placed in-line during LESS, instrument crowding becomes a clinical problem; hence, advanced skills are needed to perform this procedure. However, this in-line placement can produce a new surgical strategy in cases in which it is difficult to perform multiport laparoscopic surgery. We present a case of a large ovarian tumor with adhesions between the tumor and abdominal wall. Since the adhesions surrounded the port site in the umbilicus, we could not observe the abdominal cavity using endoscopy. We inserted the instruments through the umbilical port and completed the dissection of adhesions. Finally, we performed a bilateral salpingo-oophorectomy (BSO) in LESS.
