贲门癌胃癌根治术前动脉灌注美蓝标记的临床应用

Climical Application of Preoperative Arterial Infusion with Methylene Blue Staining as A Marker in Radical Operaton of Gastric and Cardiac Carcinoma

作者采用介入放射学方法，对１２例消化道癌症病人行术前动脉灌注美蓝染色标记，其中胃癌７例，贲门癌５例。除ｌ例胃癌患者，因癌广泛转移未能手术外．其余１１例均行根治手术，术中共清扫淋巴结８４组计１９１个，癌转移淋巴结６８个，占清扫淋巴结的３５．６％，癌转移淋巴结染色率１００％。病灶及淋巴结染色后呈鲜艳水蓝色，本法可清楚显示病灶范围和所在区域淋巴结，可验证术中是否彻底切除病灶，也为清扫范围提供了依据。除以上作用外．对不能做根治手术的病人，可通过导管行动脉药物灌注化疗。此外，作者还对操作方法，标记结果进行了讨论。

A method of interventional rafdiology with methylene blue staining as a marker for arte～tial infusion was used preoperatively in radical operation for l2 cases of gastrie and cardiac carcinomna A-mong them 7 cases were gastric carcinoma,5 cases一cardiac cancer, All patients except one (because ofwide cancerometastasis)underwent:a radical operatiOn. During operation 84 groups numbered 191 lym-phonodes were cleaned up,in which 68(35.6%)lymphonodes were cancerometastatic. The stainig rate ofthe metastatic lymphonodes;was l00%. This method is different from other stainings. Methylene blue staining as a marker for arterial infusioncan clearly show the limits of cancer foci‘and the lymphonodes in relative place In addition, it can checkwhether the cancer foci were cleaned up thoroughly or .not. In non一operationable patients it provides apossibility of performng arterial infusion chemotherapy through catheter.The manipulation and resjlts of labelling are discussed.
