• INTRODUCTION:

  To evaluate safety and excellent cosmetic outcome with laparoendoscopic single-site surgery (LESS). In this study, we compared the usefulness and efficacy of LESS versus conventional laparoscopic surgery for the treatment of urachal remnants.

  MATERIALS AND METHODS:

  We retrospectively reviewed the medical records of 20 consecutive patients who underwent either conventional laparoscopic surgery or LESS from January 2007 to February 2015 at Kansai Medical University Hospital. Ten patients underwent surgery using the standard laparoscopic 3-port technique, and 10 patients underwent LESS. The patients included 12 males and 8 females (mean age, 24.5 years; range, 10-68 years). The patients' characteristics, surgical data, and postoperative pain assessment results were retrospectively collected and analyzed.

  RESULTS:

  The median operative time, pneumoperitoneal surgery time, and estimated blood loss did not differ between the LESS and conventional laparoscopic groups. However, the total incision length was longer in the conventional laparoscopic group than in the LESS group. The degree of pain at 2 to 5 days postoperatively according to the Wong-Baker FACES Pain Rating Scale was lower in the LESS group than in the conventional laparoscopic group (p < 0.05).

  CONCLUSIONS:

  Less is a possible option in the surgical treatment for urachal remnants. In this very small cohort, there is no conversion to traditional laparoscopic surgery or open surgery. This technique is possibly feasible and may achieve less pain. Accumulation of surgical outcomes especially in safety and cosmesis is required to be an established method.
