Hernia, Inguinal Clinical Trial
Official title:
Randomised Controlled Trial on Use of Monopolar Energy Versus Blunt Dissection in Totally Extra-peritoneal Hernioplasty (TEP) for Inguinal Hernia - the Effect on the Output of Pre-peritoneal Drain
There is a long debate whether monopoloar or blunt dissection should be adopted in TEP to minimise the chance of seroma formation. This study aims at study the effect on seroma formation (and pre-peritoneal drain output) by 2 techniques in randomised controlled trial.
There is a long debate whether monopoloar or blunt dissection should be adopted in TEP to
minimise the chance of seroma formation. This study aims at study the effect on seroma
formation (and pre-peritoneal drain output) by 2 techniques in randomised controlled trial.
all male and female patients presented with first occurrence, unilateral inguinal hernia
anticipated for laparoscopic TEP are included into study after informed consent. Patients are
randomized into "diathermy-preferred" (DP) group and "blunt dissection-preferred" (BDP) group
just before commence of operation after general anaethesia. Surgeons are instructed to use
monopolar energy as main dissection method for whole operation if possible (DP), where as
blunt dissection is the preferred choice in BDP group but it is allowed to use monopolar
energy if needed. Total energy time is measured by a specially designed device attaching to
the monopolar pedals as accurate as to millisecond (ms). Pre-peritoneal drains are inserted
for drainage and removed 23 hours after operation. Energy time, drainage output, ultrasonic
seroma sizes at day 1, day 6, 1 month post-operations, recurrence are compared between 2
groups.
