First of all, single-hole laparoscopy differs from traditional multi-hole laparoscopic surgery, there are definitely some advantages: 1, minimally invasive: using a single-hole laparoscopic system equipment, entering through a single puncture hole at the mouth of the navel, automatically building the cavity and exposing the operative field; 2, aesthetic: because of the natural depression of the umbilicus, the folds can cover the incision, the incision is hidden in the pore fossa, and the appearance of the umbilicus is restored intact, thus making minimally invasive surgery enter the era of scarlessness; 3, Economy: single-hole laparoscopy allows automatic bed activity and feeding in 8-10 hours after surgery, the incision does not need to be removed, the hospital stay is short, and the medical cost is relatively low. However, single-port laparoscopy is used as a supplement to traditional multi-port laparoscopy, not as a substitute for multi-port laparoscopy.
