At present, ≥ 20% of patients experience clinically relevant postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP).
We developed a new bioabsorbable pancreatic clip (BioPaC) made of polycaprolactone that does not crush the pancreatic parenchyma during occlusion of the pancreatic stump. We confirmed the efficacy of this BioPac in a porcine DP model and compared it to a linear stapling device (Reinforce®).
Pigs were killed at 1 month after DP. In the BioPaC group, all swine (n = 3) survived well without POPF. In the Reinforce® group (n = 2), one pig died early at postoperative day 7 with Grade C POPF (amylase 43 700 U/l), and the other survived until 1 month at scarification with biochemical leakage of POPF (amylase 3 725 U/l). Pathologically, the main pancreatic duct and pancreatic parenchyma were well closed by BioPaC.
The newly developed BioPaC is effective in a porcine DP model.
目前,在远端胰腺切除术(DP)后,有≥20%的患者出现临床上相关的术后胰瘘(POPF)。
我们开发了一种由聚己内酯制成的新型可吸收性胰腺夹(BioPaC),在夹闭胰腺残端时不会压碎胰腺实质。我们在猪 DP 模型中证实了这种 BioPac 的有效性,并将其与线性吻合器(Reinforce®)进行了比较。
DP 后 1 个月处死猪。在 BioPaC 组中,所有猪(n=3)均无 POPF,且存活良好。在 Reinforce®组(n=2)中,一只猪在术后第 7 天因 C 级 POPF(淀粉酶 43700 U/L)而早期死亡,另一只猪在 1 个月时因生化漏 POPF(淀粉酶 3725 U/L)而存活。病理上,BioPaC 可很好地封闭主胰管和胰腺实质。
新开发的 BioPaC 在猪 DP 模型中有效。
