Objective: To evaluate the clinical significance of the umbilical
hole laparoscopic spermatic vein ligation in the treatment of
Methods: Forty-two patients with bilateral varicocele received
bilateral ligation using laparoscopic techniques from January
2010 to September 2010. They included 20 cases of the umbilical
hole laparoscopic group and 22 of the conventional laparoscopic
group The blood loss, testicular artery salvage, operation length,
time to ambulation after surgery, time to intestinal function
recovery and hospital stay were compared in the two groups
with semen quality measured before and one year after the
procedures. Four clinic visits were made at one month, three
months, six months and one year after surgery to evaluate
the incisions and presence of complications related to the
scrotum, spermatic cord and testis. Patients were asked to report
mitigation of discomfort feelings such as scrotum dragging.
Results: All surgeries were successful in both groups without
any event of severe complications. There was no difference in the
blood loss [(5±1) mL/ (5±1) mL, t=–0.452, P>0.05], operation
duration [(41±7) min/ (39±3) min, t=0.686, P>0.05], time
to intestinal function recovery [(11+1) h/ (11+2), t=–1.631,
P>0.05] or postoperative hospital stay [(3.1+0.7) d/ (3.4+0.7),
t=–1.447, P>0.05] between the two groups. One patient in the
hole laparoscopic group required analgesics (5.0%), less than that
(seven, 31.8%) in the conventional laparoscopic group, which was
significantly different (χ2=4.886, P<0.05). Patients who received
the umbilical hole laparoscopic procedure were almost "scarfree".
All patients completed the incision satisfaction survey one
year after the surgery, and statistical analysis revealed significant
difference between the two groups (χ2=7.636, P<0.01).
Conclusions: The umbilical hole laparoscopic surgery
provides comparable effect in bilateral spermatic vein ligation
to traditional laparoscopic surgery while being less invasive and
more aesthetic. It is a promising approach that worth promoting.
