Recently scholars pay more attention on enteral nutrition(EN).Itis a pity that EN is not prevalent as expected.Sacciform jejunun was applied to 100 cases in clinical practice in our hospital.The catherer is made in Qinxin Medical Catherer Factory.There are two varying size of cateherer-Ⅰ and Ⅱ.Ⅰ catherer has two catherers linked togther,being fit for operations of stomach,liver,pancreatic,esoplagas etc.At the same time,haso-gastric suction is necessary.The saccalus is filled with 3ml NS during operation,then the two catherers are devided naturallyed.The catherer with saccicus is placed in jejunun.Postoperative earlier enteral nutrition support are applicated.EN are satisfy used iva jejunum catherers in complication such as fistula originate from surgical sutrre line,pancreatic,gall bladder et.In our hospital,two patients with oesophagoastric fistulas were treated with EN.They received EN support for 30 days and 61 days before the fistulas healed spontanealsly.The mean duration sacciform jejunum catherers in place before removal is 10 days to 14 days.We believe it is suitable nasogastrojejunal catherers be replaced by sacciform jejunum catherers,because it provide a path for EN and haso-gastric suction.Sacciform jejunum catherer is soft,antiseptic,nonivasive and economical and accepted by patiens generally.Ⅱ catherer is a single catherer withlout the afflitiated nosogastrojejunal,being fit for patients of nonoperation or haso-gastric suction,and the means being used is similar to Ⅰ catherer.It is 10 min to 20 min before Ⅱ catherer enter jejunum.Although easiness,it is nessary to replace nosogastrojejunal with Ⅰ catherer.Patients being suitable for using saciform jejunum cather come from the Gasteroin Surfical Department,Burn Department,veurolgy Department,radio therapy and Chemotherapy Department.Thus we think it shoule be applied wildly.
