    Abstract:
    OBJECTIVE: The purpose of this retrospective study was to compare our umbilical stalk elevation (USE) technique with the classic Veress needle (VN) technique in obese patients. STUDY DESIGN: The USE technique was performed on 40 patients. One control per case was randomly selected from among those undergoing the classic VN technique using a random number table. In USE technique, a 12 mm skin incision was created at the superior crease of the umbilical fold, and the underlying subcutaneous adipose tissue was bluntly dissected using the tip of a fine clamp until the umbilical stalk was isolated at the inferior and central part of the incision. Next, the umbilical stalk was covered and held by a towel clip, and the abdominal wall was elevated by upward traction. The VN was then inserted nearly perpendicular to the incision and turned toward the pelvis immediately after resistance to the needle had been lost. A post-hoc power analysis was performed. RESULTS: The number of attempts was significantly lower in the USE laparoscopy group than in the classic laparoscopy group (1.2 ± 0.4 vs. 2.1 ± 0.7, respectively; P<0.001). The USE technique group had a slightly shorter abdominal entry time than did the classic technique group (328.52 ± 63.71 vs. 434.95 ± 124.10s; P<0.001). Six (7.5%) failed insufflations occurred in our study (5 patients in the classic group vs. 1 patient in the USE group (P=0.10). CONCLUSION: Our novel USE technique can be an effective means of establishing pneumoperitoneum in obese patients undergoing gynecologic laparoscopic procedures.
