Study on the Application Value of Mimics-Based Mono-Modality Three-Di-mensional Gastrointestinal Reconstruction Model in Intestinal Intubation De-compression for Patients with Adhesive Small Bowel Obstruction
目的 分析基于Mimics的单模态胃肠道三维重建模型在粘连性小肠梗阻患者肠插管减压术中的应用效果.方法 选取2023年2月至2024年1月于我院接受肠插管减压术的80例粘连性小肠梗阻患者,按置管方案分为两组各40例.对照组采用常规X线透视引导下置管,实验组术前通过Mimics软件构建胃肠道三维重建模型,评估导管入路并规划操作路径,联合X线透视引导完成置管.记录实验组的平均建模时间以及模型与术中影像的符合率,比较两组的操作时间、置管深度、X线曝光时间、造影剂用量、置管耐受程度、置管成功率、临床疗效及并发症发生情况.结果 实验组的平均建模时间为(20.75±6.44)min,模型与术中影像符合34例,符合率为85.00％.两组的治疗总有效率比较,差异无统计学意义(P＞0.05).与对照组相比,实验组的操作时间、X线曝光时间较短,造影剂用量较少,置管深度较高(P＜0.05).实验组的一次置管成功率高于对照组,并发症总发生率低于对照组(P＜0.05);两组的置管耐受程度分级比较,差异有统计学意义(P＜0.05),其中实验组Ⅰ级耐受占比高于对照组(P＜0.05).结论 基于Mimics的单模态胃肠道三维重建模型与粘连性小肠梗阻患者术中影像符合度较高,应用于肠插管减压术可提升一次置管成功率,延长置管深度,缩短操作时间,减少辐射暴露与造影剂用量,同时降低并发症发生风险,改善患者置管耐受度.
Objective To analyze the application effect of Mimics-based mono-modality three-dimensional gastrointestinal reconstruction model in intestinal intubation decompression for patients with adhesive small bowel obstruction.Methods A total of 80 patients with adhesive small bowel obstruction who underwent intestinal intubation decompression in our hospital from February 2023 to January 2024 were enrolled.According to the catheterization protocol,they were divided into two groups,with 40 cases in each group.The control group received conventional fluoroscopy-guided catheterization.For the experimental group,a three-dimensional gastrointestinal reconstruction model was established using Mimics software before surgery to evaluate the catheter access route and plan the operation path,and catheterization was completed under combined fluoroscopy guidance.The average modeling time and the consistency rate between the model and intraoperative images in the experimental group were recorded.The operation time,catheterization depth,X-ray exposure time,contrast agent dosage,catheterization tolerance,first-attempt success rate of catheterization,clinical efficacy and occurrence of complications were compared between the two groups.Results The average modeling time in the experimental group was(20.75±6.44)min;the model was consistent with intraoperative images in 34 cases,with a consistency rate of 85.00％.No statistically significant difference was found in the total effective rate of treatment between the two groups(P＞0.05).Compared with the control group,the experimental group had shorter operation time and X-ray exposure time,less contrast agent dosage,and greater catheterization depth(P＜0.05).The first-attempt success rate of catheterization in the experimental group was higher than that in the control group,and the total incidence of complications was lower than that in the control group(P＜0.05).Statistically significant difference was found in the grade distribution of catheterization tolerance between the two groups(P＜0.05),among which the proportion of grade Ⅰ tolerance in the experimental group was higher than that in the control group(P＜0.05).Conclusions The Mimics-based mono-modality three-dimensional gastrointestinal reconstruction model has higher consistency with intraoperative images in patients with adhesive small bowel obstruction.Its application in intestinal intubation decompression can improve the first-attempt success rate of catheterization,increase the catheterization depth,shorten the operation time,reduce radiation exposure and contrast agent dosage,lower the risk of complications,and improve patients' catheterization tolerance.
