Percutaneous transhepatic gastrostomy was performed in two patients, one with partial gastrectomy and Billroth I anastomosis and one with esophageal reconstruction with subtotal stomach, in whom oral feeding was precluded. In both patients, percutaneous gastrostomy with fluoroscopic guidance was impossible since the gastric remnants were small, had a high subcostal position, and were overlain by the transverse colon, lung and left lobe of the liver. The only route available to avoid the overlying bowel and lung was the transhepatic approach. The gastric remnants were punctured with a 22-gauge PTC needle through the left lobe of the liver with CT guidance, and an 8 Fr. Cope-type catheter was fluoroscopically placed in the gastric remnant or the duodenum after tract dilatation over the guide wire. No complications occurred during or after the procedures, and the condition of both patients was greatly improved. Although gastrostomy in patients with partial gastrectomy is thought to be very difficult, percutaneous transhepatic gastrostomy with CT guidance is easy and may be safe since adhesion between the liver and gastric remnant can prevent massive hemorrhage or displacement of the catheters.
两名患者接受了经皮肝穿刺胃造瘘术,其中一名患者行部分胃切除术及毕Ⅰ式吻合术,另一名患者行食管重建及胃大部切除术,均无法经口进食。由于两名患者的胃残余较小、位于肋弓下较高位置且被横结肠、肺和肝左叶覆盖,因此在透视引导下行经皮胃造瘘术均不可行。避免覆盖肠道和肺的唯一途径是经肝途径。在CT引导下,用22号PTC针经肝左叶穿刺胃残余,在导丝引导下扩张通道后,在透视下将8F的Cope型导管置入胃残余或十二指肠。手术过程中及术后均未发生并发症,两名患者的病情均有明显改善。虽然部分胃切除术后患者行胃造瘘术被认为非常困难,但CT引导下经皮肝穿刺胃造瘘术操作简便且可能安全,因为肝与胃残余之间的粘连可防止大出血或导管移位。
