To observe and count the probability of presence and the anatomy of the vessel arising the inferior margin of the pancreas and traveling within the transverse mesocolon, and analyze its clinical significance.
Patients who underwent radical operation for transverse colon cancer or descending colon cancer from January 2020 to November 2021 and a nonspecific cadaver were included in this study. We observed and recorded intraoperatively for the probability of presence and the anatomy of the vessel arising the inferior margin of the pancreas and traveling within the transverse mesocolon. And its property was determined by tissue slice.
A total of 84 patients were included, of which, the vessel was observed in 72 (85.7%) patients, and its property was confirmed by tissue slice of one patient after surgery. The vessel was also observed in a nonspecific cadaver. Originating from transverse pancreatic artery, often one, occasionally two, rarely three vessels arose the inferior margin of pancreas and supplied the left transverse colon. Artery and vein parallel ran, and it was difficult to separate them due to their small diameter, but the vessels may thicken under certain conditions for increasing blood supply.
The vessel, which is not yet reported and named in the literature, can be called the subpancreatic transverse colon vessel, which has a high probability of presence in humans and may be of great significance to human physiological anatomy, surgery, and oncology, and deserves recognition and attention from surgeons.
观察并计数起自胰腺下缘并走行于横结肠系膜内的血管的出现概率及解剖结构，并分析其临床意义。
本研究纳入了2020年1月至2021年11月期间接受横结肠癌或降结肠癌根治手术的患者以及一具非特异性尸体。我们在术中观察并记录起自胰腺下缘并走行于横结肠系膜内的血管的出现概率及解剖结构。并通过组织切片确定其性质。
共纳入84例患者，其中72例（85.7%）观察到该血管，术后1例患者的组织切片证实了其性质。在一具非特异性尸体中也观察到了该血管。该血管起自胰横动脉，通常为1支，偶尔为2支，很少为3支，起自胰腺下缘并供应左半横结肠。动脉和静脉并行，由于其直径较小难以分离，但在某些情况下血管可能会增粗以增加血供。
该血管在文献中尚未见报道及命名，可称为胰下横结肠血管，在人体中出现概率较高，可能对人体生理解剖、外科手术及肿瘤学具有重要意义，值得外科医生认识和关注。
