The introduction of laparoscopy has ushered in a new era of minimally invasive abdominal surgery. Over the past two decades, laparoscopic techniques have become increasingly mature and have been widely used in abdominal surgery. Almost all abdominal surgeries can now be done laparoscopically. Although laparoscopic surgery has reduced incision-related complications, it still requires a 1C3 cm long incision and 3-5 skin poke holes. The inherent risks associated with this include bleeding, infection, corresponding organ damage, hernia formation, and less than optimal appearance. With the development of medical technology, minimally invasive surgery has entered a new phase of development since the new century. Scarless, less complications, faster recovery, labor-saving and precise, and cost-saving have become the development direction of minimally invasive surgery. In this paper, by reviewing the domestic and foreign literature in recent years, we make a preliminary outlook on the development trend of minimally invasive abdominal surgery and pediatric applications. 1.needle laparoscopy Needle laparoscopy is only 2mm in diameter, so it does not require skin incision, but only direct skin puncture into the abdominal cavity, so there is no need to close the incision, less complications, and aesthetic effect. However, because of the weak strength of the 2 mm instrument, it is difficult to implement abdominal operations independently, and is currently used only in some simple operations. In China, some units have applied needle laparoscopy to treat pediatric inguinal hernia and hypertrophic pyloric stenosis. At present, needle laparoscopy is mainly used to assist single-hole laparoscopy or NOTES surgery to expand its surgical scope and improve surgical results. 2. single-port transumbilical laparoscopy (single-port transumbilical surgery) With the increasing maturity of laparoscopic techniques, new developments are dedicated to further reducing incisions and improving the appearance. One of these efforts includes single-port transumbilical laparoscopic surgery. The umbilicus is the natural orifice of the embryonic remnant, and access to the abdominal cavity is gained through the umbilicus, making abdominal scars imperceptible and avoiding the manipulation of visceral pokes in NOTES surgery. The transumbilical operation, with an entry angle similar to that of a normal laparoscopic operation, is easily accepted by surgeons. In contrast, transvaginal, transgastric or transcystic pathway procedures are more likely to be disoriented. There have been many reports in the literature on the use of a single umbilical incision for various abdominal procedures.Rane et al. pioneered the use of single-port laparoscopy in general and urologic clinical cases, and they had a total of 33 patients, of whom only 2 had nephrectomies that required an extra-umbilical incision for assistance.08 Desai et al. first reported the use of a novel design of single-port access through a single umbilical 1.5-3 cm incision In 2008, Desai et al. first reported a completely transumbilical single-port laparoscopic nephrectomy and pyeloplasty in a clinical patient through a single umbilical 1.5-3 cm incision, using a novelly designed single-port entry. In 2009, they reported more complex urological reconstructive procedures, including two bilateral Anderson-Hynes pyeloplasties, one ileal substitution ureter and one uretero-vesical anastomosis. Intraoperatively, only one 2-mm Veress port was placed through skin puncture to create a pneumoperitoneum, or a needle grasper was selectively placed to assist in the anastomosis.
