Abstract: This study was designed to evaluate the safety and efficacy of
suprapubic-assisted umbilical laparoendoscopic mini-dual-site surgery
(SAU-LEMDS) with satisfied cosmetic outcome in minimal size of surgical
incision for the treatment of simple kidney cyst at large size. Twenty-six
consecutive patients (16 male and 10 female), aged 48.5 ±
4.1 years (range: 18 to 70 years), were enrolled in this study. All cases had
simple kidney cysts including 18 cases on the left side and 8 cases on the
right, with a mean cyst maximum diameter of 7.5 ± 0.8 cm.
Under general anesthesia, the patients were placed in flank position with
affected side elevated by 70°. Two trocars (5.5 mm in
diameter) were inserted via the umbilical port. The third trocar was inserted
into abdominal cavity above the pubic hairline for the placement of a 5-mm
30° laparoscope. The surgery procedures were
successfully performed in the same manner as standard laparoscope-assisted
kidney cyst decortication in all cases. The specimens were obtained through
either of two umbilical ports without additional enlarge incisions. The mean
operation time was 30 ± 8.2 min and the mean blood loss
was 10.3 ± 2.1 ml. The duration of hospitalization was
4.2 ± 0.9 days, and the mean follow-up was two months
(range: 1 to 3 months). Postoperatively, surgical wounds were small and healed
well and cosmetic outcomes were satisfactory. No recurrent kidney cysts were
found during follow up. SAU-LEMDS appears to be a feasible, safe and effective
surgical option for simple kidney cyst, which not only leads to better cosmetic
effects, but also decreases the complexity of umbilical laparoendoscopic single
site surgery (U-LESS).
