探究经脐单孔腹腔镜及常规腹腔镜阑尾切除术对阑尾炎患儿围手术期指标、术后并发症的影响。

回顾性分析2021年9月至2024年12月收治的急性阑尾炎患儿的临床资料，通过倾向评分匹配排除性别、年龄、发病至手术时间等混杂因素，将采用常规腹腔镜阑尾切除术的60例患儿设为对照组，将采用经脐单孔腹腔镜阑尾切除术的60例患儿设为研究组。数据通过SPSS 23.0软件处理分析，并进行正态性检验。符合正态分布的计量资料用（±s）表示，组间比较行独立样本t检验；性别和不良反应等计数资料用[例（%）]表示，行χ²检验，理论频数<5时采用Fisher精确检验；不符合正态分布的数据进行对数变换。P<0.05表示差异有统计学意义。

与对照组相比，研究组患儿手术时间较长，切口长度、术后首次排气时间、术后首次进食时间和术后首次排便时间较短（P<0.05）。两组患儿的术中出血量、住院时间和术后并发症发生率比较差异无统计学意义（P>0.05）。术后3d，两组患儿的降钙素原（PCT）、白细胞介素-6 （IL-6）和C反应蛋白（CRP）水平均升高，但研究组较对照组低（P<0.05）。随访2个月，研究组患儿温哥华瘢痕评价量表（VSS）评分低于对照组（P<0.05）。

相较于常规腹腔镜阑尾切除术，经脐单孔腹腔镜阑尾切除术虽难度更大、时间更长，但该术式能有效减小手术创伤，加快患儿术后肠功能恢复，并有效减轻炎症反应，且安全性较好。

To explore the impact of transumbilical single-port laparoscopic appendectomy and conventional laparoscopic appendectomy on perioperative indicators and postoperative complications in children with appendicitis.

A retrospective analysis was performed on the clinical data of children with acute appendicitis admitted from September 2021 to December 2024. Confounding factors such as gender, age, and time from onset to surgery were excluded by propensity score matching. Sixty children who underwent conventional laparoscopic appendectomy were set as the control group, and 60 children who underwent transumbilical single-port laparoscopic appendectomy were set as the study group. Data were processed and analyzed using SPSS 23.0 software, with normality tests conducted. Measurement data conforming to normal distribution were expressed as (±s), and independent sample t tests were used for intergroup comparisons; gender and adverse reaction data were expressed as [cases (%)], and χ² tests were performed (Fisher’s exact test was used when the theoretical frequency <5); data not conforming to normal distribution were logarithmically transformed. P<0.05 was considered statistically significant.

Compared with the control group, the study group had longer operation time, but shorter incision length, first exhaust time after surgery, first feeding time after surgery, and first defecation time after surgery (P<0.05). There were no significant differences in intraoperative blood loss, hospital stay, or incidence of postoperative complications between the two groups (P>0.05). Three days after surgery, the levels of procalcitonin (PCT), interleukin-6 (IL-6), and C-reactive protein (CRP) increased in both groups, but were lower in the study group than in the control group (P<0.05). After 2 months of follow-up, the Vancouver Scar Scale (VSS) score of the study group was lower than that of the control group (P<0.05).

Compared with conventional laparoscopic appendectomy, transumbilical single-port laparoscopic appendectomy, despite being more difficult and time-consuming, can effectively reduce surgical trauma, accelerate postoperative intestinal function recovery, alleviate inflammatory response, and demonstrate good safety.
