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.

Lint (material) abdominal hair often seems to grow in concentric circles around the navel; the scaly structure of the hair enhances the abrasion of minuscule fibres from the shirt and directs the lint towards the belly button. Steinhauser established that shaving one's belly will result in a fluff-free navel but only until the hairs grow back. His other suggestions include wearing old clothes, which tend to shed less lint than newer garments, which can lose up to one-thousandth of their weight to the belly button over the course of a year. A body piercing can also be used, with belly button rings
