目的

探讨基于CT测量的肥胖指标对腹腔镜括约肌间切除术(Lap-ISR)术后3个月内吻合口并发症的预测价值。

方法

纳入火箭军特色医学中心2022年5月至2024年6月因超低位直肠癌接受Lap-ISR的192例患者,收集术后3个月内吻合口并发症数据。根据并发症发生情况分组,采用单因素分析筛选危险因素,进一步通过多因素Logistic回归、性别分层分析及ROC曲线评估内脏脂肪面积(VFA)与肾周脂肪面积(PFA)的预测效能。

结果

吻合口并发症发生率为18.2%(35/192)。单因素分析显示:男性(P=0.013)、糖尿病(P=0.036)、部分ISR(vs次全/完全ISR,P=0.026)、VFA≥100 cm2P=0.009)、PFA≥25 cm2P=0.007)显著增加并发症风险。多因素Logistic回归证实:男性(OR=2.84,95%CI:1.12~7.21,P=0.042)、VFA≥100 cm2OR=3.12,95%CI:1.15~8.45,P=0.028)、PFA≥25 cm2OR=4.25,95%CI:1.82~9.92,P=0.006)为独立危险因素。性别分层分析:仅在男性中,PFA≥25 cm2与并发症显著相关(P=0.032);女性中无关联(P=0.62)。ROC曲线:PFA预测效能(AUC=0.659,95%CI:0.549~0.769,P=0.003)优于VFA(AUC=0.642, 95%CI:0.530 ~0.754,P=0.009)。

结论

PFA是预测Lap-ISR术后吻合口并发症的可靠指标,对男性患者价值尤为突出。术前PFA≥25 cm2提示高风险,手术建议由经验丰富的医生操作,并需加强围手术期管理。

Objective

To explore the predictive value of obesity-related metrics based on CT measurements for anastomotic complications within three months after laparoscopic intersphincteric resection (Lap-ISR).

Methods

A total of 192 patients who underwent Lap-ISR for ultra-low rectal cancer at the Characteristic Medical Center of PLA Rocket Force from May 2022 to June 2024 were included. Data on anastomotic complications within three months after surgery were collected. The patients were divided into groups based on the occurrence of complications. Univariate analysis was performed to screen risk factors, and further multivariate logistic regression analysis, gender-stratified analysis, and receiver operating characteristic (ROC) curve analysis were conducted to evaluate the predictive effectiveness of visceral fat area (VFA) and perirenal fat area (PFA) for Lap-ISR anastomotic complications.

Results

The incidence of anastomotic complications was 18.2% (35/192). Univariate analysis showed that male gender (P=0.013), diabetes (P=0.036), partial ISR (vs subtotal/complete ISR, P=0.026), VFA≥100 cm2 (P=0.009), and PFA ≥25 cm2 (P=0.007) significantly increased the risk of anastomotic complications. Multivariate logistic regression confirmed that male gender (odds ratio [OR]=2.84, 95% confidence interval [CI]: 1.12~7.21, P=0.042), VFA≥100 cm2 (OR=3.12, 95%CI: 1.15~8.45, P=0.028), and PFA ≥25 cm2 (OR=4.25, 95%CI: 1.82~9.92, P=0.006) were independent risk factors. Gender-stratified analysis showed that PFA≥25 cm2 was significantly associated with complications (P=0.032) only in males, but not in females (P=0.62). ROC curve analysis showed that PFA had a better predictive performance (area under the curve [AUC]=0.659, 95%CI: 0.549~0.769, P=0.003) compared to VFA (AUC=0.642, 95%CI: 0.530~0.754, P=0.009).

Conclusion

PFA is a reliable indicator for predicting anastomotic complications after Lap-ISR, with particular significance for male patients. A preoperative PFA≥25 cm2 indicates a high risk, suggesting that surgery should be performed by an experienced surgeon with enhanced perioperative management.
