Single-port laparoscopy Single-port laparoscopy Single-port laparoscopy (SPL), is a recently developed technique in laparoscopic surgery. It is a minimally invasive surgical procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient’s navel. Unlike a traditional multi-port laparoscopic approach, SPL leaves only a single small scar. SPL is accomplished through a single 20 mm incision in the navel (umbilicus or belly button), or through only a 11 mm incision in the navel, minimizing the scarring and incisional pain associated with the multiple points of entry used during traditional laparoscopic surgery. Specialized equipment for SPL surgery falls into
Navel to the junction between the L3 and L4 vertebrae, with a normal variation among people between the L3 and L5 vertebrae. Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the scar left by the detachment of the umbilical cord. This is located in the centre of the navel, sometimes described as the "button". Attached round the umbilical cord remnant, is the "umbilical collar", formed by the dense fibrous umbilical ring. Surrounding this is the periumbilical skin. Directly behind the navel is a thick fibrous cord formed from the umbilical cord, called the urachus,
