Inguinal hernia is one of the most common surgical diseases. Over the past years, the safety
and feasibility of laparoscopy was established and gaining popularity in recent few years.
Laparoscopic inguinal hernia repair was associated with less post operative pain, a shorter
recovery period, earlier return to normal daily activities and work, and better cosmetic
results. The laparoscopic hernia repair usually require three working ports ranging from 5 to
10 mm. However, with each increasing laparoscopic ports usually associated with possible
increasing morbidity and pain related to ports.
Efforts are continuing to further reduce the port related morbidities and improve the
cosmetic outcomes of laparoscopic surgery, including reduction of the size and number of
ports. This has led to the evolution of a novel surgical approach now collectively known as
laparoendoscopic single site surgery. LESS has been performed for variable indications
including extirpative and reconstructive urologic procedure via the transperitoneal approach.
Early experience has demonstrated the feasibility as well as the safe and successful
completion of these LESS procedures. Although these initial reports are promising, the
clinical advantages of LESS procedures over conventional laparoscopic procedures have not
been defined. Therefore, we conducted a single center, randomized trial to compare the safety
and other outcomes after conventional laparoscopic and LESS inguinal hernia repair in adult
