Measures to anatomical variation of perigastric vessels during laparoscopic gastric cancer surgery / 中华胃肠外科杂志

ABSTRACT

Laparoscopic gastric cancer surgery, which has been gradually accepted by surgeons and popularized worldwide, is a less invasive alternative compared with an open procedure. However, the lack of cognition of the variation in perigastric vessels, and the difficulty to obtain a full-view image and to estimate the three-dimensional (3D) relationships between organs during laparoscopic procedures may lead to unexpected injuries of these vessels, causing massive bleeding, which would prevent surgeon from having access to a good view of the operative field. We retrospectively summarize the data of laparoscopic gastric cancer operation in our hospital, separate the perigastric vessels into three areas according to the procedure, respectively the inferior pylorus, superior pancreas, and hilum of spleen, and analyze the common anatomical variation of vessels and its characters. We propose that, following the right anatomical spaces, the familiarity of perigastric vessels and skills of treating its common anatomical variations, may contribute to the safe and effective operation, improve the level of lymph node dissection, and reduce the injury in the operation.
