单孔腹腔镜腹股沟疝经腹腹膜前修补术兼具微创与美容优势，能实现腹壁"无瘢痕"，适配瘢痕体质和对无瘢痕有要求的患者。该术式与完全腹膜外修补术同为单孔腹膜前修补经典入路，但因操作门槛高、学习曲线陡峭，临床应用中占比仅约1/10。本文结合实践经验与医保按病种付费要求，详解其关键技术：创新穿脐"兔唇"样切口，搭配常规穿刺器，兼顾隐蔽性与经济性；针对视野局限、器械干扰等问题，通过维持微张力、交叉牵引、优化镜头位置应对；采用3-0倒刺线"单手缝合"破解腹膜缝合难点；规范切口消毒、全层关闭及脐部整形以降低并发症。掌握该技术需反复训练，可为患者提供更优质微创体验。

Single-incision laparoscopic transabdominal preperitoneal inguinal hernia repair integrates the advantages of minimal invasiveness and aesthetic outcomes, enabling "scar-free" abdominal wall restoration. It is particularly suitable for patients with scar-hypertrophic diathesis or those with explicit demands for scarless healing. As a classic single-incision preperitoneal repair approach alongside total extraperitoneal repair (TEP), it accounts for merely approximately 10% of clinical applications due to its high technical threshold and steep learning curve. Drawing on practical experience and the requirements of diagnosis-related group (DRG)-based medical insurance payment, this article elaborates on its core technical points in detail: an innovative umbilical "cleft lip-like" incision combined with conventional trocars, balancing concealment and cost-effectiveness; addressing challenges such as limited surgical field of view and instrument interference through maintaining micro-tension, cross-traction, and optimizing laparoscope positioning; utilizing 3-0 barbed suture for "one-handed suturing" to overcome the technical difficulty of peritoneal closure; and standardizing incision disinfection, full-thickness closure, and umbilical plastic surgery to reduce complications. Proficiency in this technique requires repeated training, which can offer patients a superior minimally invasive surgical experience.
