Abstract

Purpose: This study investigated whether blood loss (BL) was. truly less in patients undergoing laparoscopic pancreaticoduodenectomy (LPD) than in those undergoing open pancreaticoduodenectomy (OPD).

Methods: A total of 98 patients undergoing pancreaticoduodenectomy between 2021 and 2023 were divided into OPD and LPD groups and compared. Estimated BL was calculated from the perioperative changes in hematocrit, hemoglobin, or red blood cell volume. Actual BL was calculated using the conventional method as the sum of the intraoperative aspirated blood volume and surgical gauze weight.

Results: Actual BL was significantly lower in the LPD group than in the OPD group (150 [80-350] ml vs. 345 [150-700] ml, p = 0.003). However, there were no significant differences in the estimated BL calculated from the hematocrit (461 [187-626] ml vs. 351 [153-737] ml, p = 0.972), hemoglobin, or red blood cell volume. Estimated BL showed a stronger linear correlation with actual BL in the OPD group (r = 0.447-0.669) than in the LPD group (r = 0.158-0.417). OPD was not a significant factor in the increased estimated BL.

Conclusions: The conventional method for calculating the BL in LPD may underestimate the actual loss, highlighting the need for a more accurate method of evaluation.

传统的失血量计算方法可能低估了腹腔镜胰十二指肠切除术的真实失血量：一个双研究所的经验。

目的：探讨血量损失（BL）的临床意义。腹腔镜胰十二指肠切除术（LPD）的发生率低于开放式胰十二指肠切除术（OPD）。方法：将2021 ~ 2023年行胰十二指肠切除术的98例患者分为OPD组和LPD组进行比较。根据围手术期红细胞压积、血红蛋白或红细胞体积的变化来计算估计的BL。实际BL采用常规方法计算术中吸血量与手术纱布重量之和。结果：LPD组实际BL明显低于OPD组（150 [80-350]ml vs. 345 [150-700] ml, p = 0.003）。然而，通过红细胞比容（461 [187-626]ml vs. 351 [153-737] ml, p = 0.972）、血红蛋白或红细胞体积计算的估计BL没有显著差异。相比于LPD组（r = 0.158-0.417）， OPD组估计BL与实际BL的线性相关性更强（r = 0.447-0.669）。结论：传统的LPD计算方法可能低估了LPD的实际损失，因此需要一种更准确的评估方法。

期刊介绍： Surgery Today is the official journal of the Japan Surgical Society. The main purpose of the journal is to provide a place for the publication of high-quality papers documenting recent advances and new developments in all fields of surgery, both clinical and experimental. The journal welcomes original papers, review articles, and short communications, as well as short technical reports("How to do it"). The "How to do it" section will includes short articles on methods or techniques recommended for practical surgery. Papers submitted to the journal are reviewed by an international editorial board. Field of interest: All fields of surgery.
