Abstract

Introduction: The objective of this study was to collect and analyze data on patient demographics, lifestyle, abdominal cavity characteristics, and their impact on intra-abdominal pressure before and after minimally invasive treatment of large parietal defects in hernia pathology. Additionally, the study examines the role of the CT scan as a reliable and valid measure of defect and muscle characteristics, which can help establish the indication for performing Transversus Abdominis Release (TAR) and evaluate the outcomes of this procedure along with differences in intra-abdominal pressure (IAP) and plateau pressure (Pplat). Methods: This prospective study involved 20 patients with parietal defects wider than 10 cm, treated over four years at the Central Military Hospital in Bucharest. All procedures were performed using the laparoscopic TAR technique by the same surgical team. Preoperative assessments included CT imaging to measure defect size, volumes, and IAP. Data including defect dimensions, muscle measurements, IAP, and Pplat were systematically recorded in a dedicated database with a follow-up at 6 months with clinical and imaging evaluations. Results: In our cohort of 20 patients, all female, the mean BMI was 26.81+-3.05, and the hernia sac volume (HSV) averaged 159.01+-189.79 cm³. The defect area was 69.53 cm² (+-30.11). IAP decreased from 5 cmH2O (+-1.28) preoperatively to 1.91 cmH2O (Ã+-1.93) postoperatively. The reduction in Pplat was similarly significant. Pressure variations were influenced by the topographic location of the defect, with higher pressures seen in epigastric defects, and by the characteristics of the peritoneo-fascial defects, including number, size, and localization, which affect pressure outcomes. Additionally, dimensions of the anterior-lateral abdominal muscles correlated with pressure changes. These findings highlight the importance of comprehensive preoperative assessment of defect characteristics, muscular anatomy, and defect location for predicting pressure reductions and guiding surgical planning. Conclusions: Higher BMI and large, multiple parietal defects predict increased IAP and Pplat postoperatively. Preoperative volumetric and morphometric parameters, defect localization, and topographic characteristics significantly influence pressure outcomes. The TAR technique effectively manages large defects while minimizing pressure increases, but consideration of morphological factors is crucial for optimal results. Further research is needed to refine patient selection and surgical strategies.

腹腔镜腹侧松解术对前壁大缺损患者腹内压力的影响。
前言:本研究的目的是收集和分析疝病理大壁缺损微创治疗前后患者人口统计学、生活方式、腹腔特征及其对腹内压的影响。此外,该研究还探讨了CT扫描作为一种可靠有效的缺陷和肌肉特征测量方法的作用,它可以帮助确定腹侧松解术(TAR)的适应症,并评估该手术的结果以及腹内压(IAP)和平台压(Pplat)的差异。方法:这项前瞻性研究纳入了20例在布加勒斯特中央军事医院治疗四年的壁宽缺陷大于10厘米的患者。所有手术均由同一外科团队使用腹腔镜TAR技术进行。术前评估包括CT成像测量缺陷大小、体积和IAP。包括缺陷尺寸、肌肉测量、IAP和Pplat在内的数据系统地记录在专用数据库中,并在6个月后进行临床和影像学评估随访。结果:20例患者均为女性,BMI平均值为26.81+-3.05,疝囊体积(HSV)平均值为159.01+-189.79 cm³。缺陷面积为69.53 cm²(+-30.11)。IAP由术前的5 cmH2O(+-1.28)降至术后的1.91 cmH2O (Ã+-1.93)。Pplat的降低也同样显著。压力变化受缺陷的地形位置(上腹部缺陷的压力较高)以及影响压力结果的腹膜-筋膜缺陷的特征(包括数量、大小和定位)的影响。此外,腹前外侧肌的尺寸与压力变化相关。这些发现强调了全面的术前评估缺损特征、肌肉解剖和缺损位置对预测减压和指导手术计划的重要性。结论:较高的BMI和较大的、多重的顶板缺陷预示着术后IAP和Pplat的增加。术前体积和形态参数、缺陷定位和地形特征显著影响压力结果。TAR技术在最大限度地减少压力增加的同时有效地管理大缺陷,但形态学因素的考虑对于最佳结果至关重要。需要进一步的研究来完善患者选择和手术策略。

期刊介绍: Chirurgia is a bimonthly journal. In Chirurgia, original papers in the area of general surgery which neither appeared, nor were sent for publication in other periodicals, can be published. You can send original articles, new surgical techniques, or comprehensive general reports on surgical topics, clinical case presentations and, depending on publication space, - reviews of some articles of general interest to surgeons from other publications. Chirurgia is also a place for sharing information about the activity of various branches of the Romanian Society of Surgery, information on Congresses and Symposiums organized by the Romanian Society of Surgery and participation notes in other scientific meetings. Letters to the editor: Letters commenting on papers published in Chirurgia are welcomed. They should contain substantive ideas and commentaries supported by appropriate data, and should not exceed 2 pages. Please submit these letters to the editor through our online system.
