The resection margin status is a significant surgical prognostic factor for the long-term outcomes of patients undergoing pancreaticoduodenectomy (Whipple procedure). As a result, surgeons frequently rely on intraoperative consults (IOCs) involving frozen sections to evaluate margin clearance during these resections. Nevertheless, the impact of this practice on final margin status and long-term outcomes remains a topic of debate. This study aimed to assess the impact of IOCs on the clearance rate of resection margins following Whipple procedure and distal pancreatectomy. A retrospective database review of all patients who underwent Whipple procedure or distal pancreatectomy at our institution between 2018 and 2020 was performed to evaluate the utility of IOCs by gastrointestinal surgeons and its correlation with final postoperative surgical margin status. A significant variation in the frequency of IOC requests for margins among surgeons was noted. However, the use of frozen section analysis for intraoperative margin assessment was not significantly associated with the clearance rate of final post-operative margins. More frequent use of IOC did not result in higher final margin clearance rate, an important prognostic factor following Whipple procedure.
切缘状态是接受胰十二指肠切除术(惠普尔手术)患者长期预后的一个重要手术预后因素。因此,外科医生在这些手术中经常依靠术中会诊(IOC)及冰冻切片来评估切缘情况。然而,这种做法对最终切缘状态和长期预后的影响仍是一个有争议的话题。本研究旨在评估术中会诊对惠普尔手术和胰体尾切除术后切缘清除率的影响。对2018年至2020年间在本机构接受惠普尔手术或胰体尾切除术的所有患者进行回顾性数据库分析,以评估胃肠外科医生进行术中会诊的效用及其与术后最终手术切缘状态的相关性。结果发现,外科医生对切缘进行术中会诊的频率存在显著差异。然而,使用冰冻切片分析进行术中切缘评估与术后最终切缘清除率并无显著关联。更频繁地进行术中会诊并不会导致更高的最终切缘清除率,而切缘清除率是惠普尔手术后一个重要的预后因素。
