Abstract:
Objective:To analyze the value of abdominal CT angiography (CTA) and three-dimensional reconstruction fusion technology for larger (2 - 5 cm) gastric submucosal tumors (SMT) in the preoperative evaluation of super minimally invasive surgery(SMIS).Methods:A retrospective study was conducted, collecting data from 20 patients with gastric SMTs measuring 2 - 5 cm in diameter who were hospitalized in the the First Medical Center of the Chinese PLA General Hospital from March 2023 to December 2024. All patients underwent abdominal CTA prior to SMIS, and three-dimensional reconstructions of the tumors were performed. Clinical data were collected to analyze the visualization of the tumors and surrounding blood vessels in the fused three-dimensional images and the corresponding surgical plans.Results:In 19 cases, the abdominal CTA and three-dimensional imaging clearly and intuitively displayed the anatomical structures surrounding the tumors and provided panoramic images of small blood vessels around the tumors, enabling the selection of appropriate surgical plans. One case required conversion to laparoscopic surgery due to the intraoperative discovery of a small artery.Conclusions:The abdominal CTA examination and gastric SMT three dimensional reconstruction before SMIS can better display the anatomical location of the tumor and its relationship with surrounding small blood vessels, which is beneficial for gastroenterologists to formulate surgical plans and facilitate the smooth progress of SMIS under endoscopy.
