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.

Cultural views on the navel trikinis for beach or pool scenes. Japan has long had a special regard for the navel. During the early Jōmon period in northern Japan, three small balls indicating the breasts and navel were pasted onto flat clay objects to represent the female body. The navel was exaggerated in size, informed by the belief that the navel symbolizes the center of where life begins. On many middle Jomon figurines, the significance of the navel was emphasized with an indentation or hole. Sometimes, the importance of the navel was further enhanced by connecting with a line from the navel towards the chest.
