初步探讨后鞘后入路单孔腹腔镜全腹膜外补片修补术（SIL-TEP）治疗腹股沟疝的有效性及安全性。

选择2024年5—8月，皖南医学院第一附属医院实施后鞘后入路SIL-TEP术的腹股沟疝患者20例。收集和分析患者的临床资料，对临床数据进行标准化处理及统计学分析，并分享手术体会和经验。

20例患者中，男性16例，女性4例，年龄（68.10±10.32）岁；所有患者均为单侧腹股沟斜疝（右侧9例，左侧11例）；所有手术均顺利完成，手术时间（55.85±15.89）min，术中出血量（3.85±1.13）ml；术后下地时间（22.50±8.87）h，术后均轻微疼痛，术后第1天视觉模拟评分为（1.20±0.52）分，术后住院时间[1（1，1）]d；术后均无并发症发生。在平均14.5（13~16）个月的随访期内，均无疝复发、慢性疼痛、补片感染或切口疝。

后鞘后入路SIL-TEP术治疗腹股沟疝相对安全、有效，是一种值得推广的可靠术式。

To preliminarily explore the efficacy and safety of posterior sheath posterior approach single-incision laparoscopic totally extraperitoneal mesh repair (SIL-TEP) in the treatment of inguinal hernia.

From May 2024 to August 2024, 20 patients with inguinal hernia who underwent posterior sheath posterior approach SIL-TEP at the First Affiliated Hospital of Wannan Medical College were selected. We collected and analyzed the clinical data of these patients, standardized and statistically analyzed the clinical data, and shared surgical experiences and insights.

Among the 20 patients, 16 were male and 4 were female, with an average age of (68.10±10.32) years. All patients had unilateral indirect inguinal hernia (9 cases on the right side and 11 cases on the left side). All operations were completed successfully, with an average operation time of (55.85±15.89) min and an average intraoperative blood loss of (3.85±1.13) ml. The average time to get out of bed after surgery was (22.50±8.87) h. All patients had mild pain after surgery, with a visual analogue scale (VAS) score of (1.20±0.52) points on the first day after surgery. The average postoperative hospital stay was [1(1, 1)] d. No postoperative complications occurred. During an average follow-up period of 14.5 months (ranging from 13 to 16 months), there was no hernia recurrence, chronic pain, mesh infection, or incisional hernia.

The posterior sheath posterior approach SIL-TEP is a safe, effective, and reliable surgical method for inguinal hernia, which is worthy of promotion.
