Single-port laparoscopy
（重定向自Single Incision Laparoscopic Surgery）
Single-port laparoscopy (SPL), also known as single-port access surgery (SPA), single-port incisionless conventional equipment-utilizing surgery (SPICES), single-incision laparoscopic surgery (SILS), Single-access endoscopic surgery (SAES), laparo-endoscopic single-site surgery (LESS), natural-orifice transumbilical surgery (NOTUS), and one-port umbilical surgery (OPUS), 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.
