PURPOSE
To evaluate the feasibility of modified fusion imaging (MFI) combining CT gastrography (CTG) and CT angiography (CTA) in the preoperative mapping and intraoperative localization of small (<3 cm) submucosal lesions (SMLs) during laparoscopic exogastric wedge resection.
METHODS
Thirty consecutive patients scheduled for laparoscopic wedge resection of small SMLs (<3 cm) were enrolled. MFI was reconstructed using a volume rendering of the arterial phase CT data acquired after gastric distension. With MFI, the possibility of preoperative mapping and feasibility for successful intraoperative localization was evaluated using intraoperative findings as the reference standard.
RESULTS
In 21 of 30 patients (70%), preoperative mapping was possible. Preoperative mapping was feasible for successful intraoperative localization in 13 of 14 patients (93%) who underwent exogastric resection.
CONCLUSIONS
MFI combining CTG and CTA is a feasible method for developing preoperative and intraoperative "road maps" for performing laparoscopic exogastric wedge resection of small SMLs.
目的
评估在腹腔镜外胃楔形切除术中，将CT胃造影（CTG）与CT血管造影（CTA）相结合的改良融合成像（MFI）用于术前定位和术中定位小（<3 cm）黏膜下病变（SML）的可行性。
方法
连续纳入30例计划行小SML（<3 cm）腹腔镜楔形切除术的患者。使用胃扩张后采集的动脉期CT数据进行容积再现重建MFI。以术中结果为参考标准，利用MFI评估术前定位的可能性以及成功进行术中定位的可行性。
结果
30例患者中有21例（70%）可行术前定位。在14例行外胃切除术的患者中，13例（93%）的术前定位对于成功进行术中定位是可行的。
结论
CTG与CTA相结合的MFI是一种可行的方法，可为小SML的腹腔镜外胃楔形切除术制定术前和术中“路线图”。
