INTRODUCTION & OBJECTIVES: Laparoendoscopic single site surgery (LESS) continues to gain prevalence in
urology, with reported equivalent perioperative outcomes and superior cosmesis to conventional laparoscopic surgery
(CLS). The purpose of this study was to evaluate patient-reported satisfaction and cosmesis of LESS in comparison
with that of CLS in Japanese.
MATERIAL & METHODS: A total of 19 and 104 patients who underwent LESS and CLS between May 1996 and June
2011 were included in the study. Questionnaires inquiring about scar pain (0: not painful, 10: very painful), satisfaction
(0: not satisfied, 10: very satisfied), and cosmesis (0: very ugly, 10: very beautiful) on the basis of a visual analogue
scale that was sent to patients postoperatively.
RESULTS: Eleven (4 men and 7 women) and 52 (24 men and 28 women) patients who underwent LESS and CLS,
respectively, responded. The mean follow-up times after surgery were 64.9 (range 18-181) and 11.4 (range 5-19)
months for the CLS and LESS groups, respectively (p < 0.001). There was no significant inter-group difference in age,
male-to-female ratio, affected side, BMI, and blood loss. Insufflation time was significantly longer in the LESS group
than the conventional group (229 vs. 177 min, p = 0.041). Results of patient-reported cosmesis outcomes stratified by
operative approach are shown in Table #1. There was no significant difference in pain (p = 0.393), satisfaction (p =
0.453), and cosmesis score (p = 0.487). In female patients, satisfaction score was significantly higher in the LESS
group than the conventional group (p = 0.049).
